background

all the places where people exist can not be kept away from various articles needed by people. In order to be placed neatly and conveniently and to utilize space, people need to hang the objects. Therefore, the hook rack becomes a necessary facility for people. The existing hook rack has more classifications, and the fixing mode is also a five-flower eight-door. The hanger bracket of each mode has its special limitation, can't adjust the transform and adapt to different needs as required. For example, toilet hooks, kitchen hooks, clothing hooks, office hooks, car hooks, cabinet hooks, door hooks, public hooks, etc. are required to be constructed and arranged in various ways. The hook racks are fixed by direct screw fixation, adhesive attachment, suction attachment, 3M double-sided adhesive attachment, hanging attachment, and the like. These numerous categories allow the user to select which hanger bracket he wants and has the ability to secure, depending on his application. But are notoriously difficult to produce and the market cannot fully comply with the requirements of each user. The hanger frame with the function satisfied by the user appears, and the hanger frame can not be installed by the user; the function and appearance of the hook rack which can be installed by a user can not be met; the hook rack can be used temporarily, is convenient to carry and fix, is convenient to fold and can be taken off and taken away; in places where the detergent is used for a long time, the detergent is also required to be convenient to clean, for example, the detergent can be decomposed to come and be cleaned independently; for women and old people and people without technical and manual abilities, the hook rack which can be installed and fixed by themselves needs to be provided; what is needed for the technical personnel is a hanger frame which can be fixed by screws once and for all; the user hopes to use a dead hook, and the hung object is easy to hang up and pick down. The movable hook is inconvenient to use because of easy swinging and rotation; for the distance position between the hooks, a user wants to adjust the distance according to the requirement of the user, and particularly when the hooks are cleaned, the user wants to detach the hooks for cleaning respectively; the hook frame does not completely use the hook itself, and other functions such as hanging objects and supporting are needed. For example, the functions of hanging towels, placing things, hanging garbage bags and the like. The prior art hook can not completely meet the requirements. People need a dead hook when using, because the movable hook is not easy to take up and down due to the activity of the hook, no matter what the object is hung or taken; on the other hand, people hope that the hook is a movable hook, the distance can be adjusted at will, and the hook is convenient to take down for cleaning. Therefore, a movable hook capable of locking reliably is needed; for most of the people, the hooks which are high in quality and low in price are needed most, and the hook structure in the prior art also has the problems of being not simple enough in structure, low in cost, relatively complex in manufacturing process, not convenient enough to install, not beautiful enough in appearance and the like. Thus, the need for a hanger has not been completely met. In addition, the common hook rack is influenced by the length or the number of hooks, and cannot meet the requirements of users.

The flexible hanging arm of patent No. 2012104021614 is a hanger bracket provided with a bar for hanging hand towels, which bar provides convenience to the user. The folding towel bar is folded and attached to the wall under the action of gravity when not in use. This folding requires the hinge holes to be located relatively far from the wall to form a standing angle. When the towel bar (stainless steel tube) is connected to the front end of the wire arm made of steel wire, the towel bar needs to cross 90 degrees to be tightly leaned on the wall by gravity, and the structure causes the slide to extend forwards for a considerable distance, which brings the complexity of the fixing device. In addition, the connection between the towel bar and the steel wire can not form a sleeve shape, which easily causes the distortion of the towel bar in the folding process, therefore, the towel bar connecting device and the pin locking device are relatively unreliable and have poor hand feeling.

The hinge shaft hole 21 is a groove formed on the surface of the adhesive plate 22.

The invention has the technical effects that: the structure with only one fixing device can provide the simplest fixing mode for a user, namely, the fixing device can fix a little under the condition of using the multi-hook functional hook frame, not only occupies less wall space, but also has the characteristic of convenient fixing and has novel and unique appearance; the fixing device is provided with a structure of a slide way front fixing sleeve with reinforcing ribs at the middle end and a rear fixing sleeve at the two ends, so that the slide way has the anti-distortion capability after being fixed, namely when an object is hung on one side, the balance state of the slide way can be still kept, and feasible and reliable technical guarantee is provided for the structure of the single fixing device; the structure can also provide guarantee for the connection of the two slideways in the middle, namely when the slideways need to be connected to form a long slideway erected by two fixing devices, although the connection part is connected in the middle, because the two connected slideways are ensured not to be distorted and drooped by the respective fixing devices, the middle connection part can not be drooped, and the slideways can be connected with one another safely; the method can be suitable for the requirements of the decomposition, storage and postal delivery of the long slideway and the requirement of a user on a transformation combination method of dividing the whole into parts and dividing the whole into parts; the plastic bonding plate and the fixed sleeve are integrated, so that the structure is simplified, parts are reduced, and the manufacturing cost is reduced; the fixing sleeve is divided into a front fixing sleeve structure and a rear fixing sleeve structure, so that the problem that the appearance is influenced by the fact that the fixing sleeve is too wide due to distortion prevention is solved, the fixing sleeve is not visually wide, and the effect of distortion prevention is actually achieved; the front fixing sleeve is provided with a narrow band reinforcement protruding outwards to ensure the bearing capacity without influencing the appearance effect; the structure of the front fixing sleeve and the rear fixing sleeve can simplify the structure of the die, the structure simplifies the process of processing the die and the injection molding process, and reduces the cost; the two sliding sleeves of the two self-locking hooks are respectively inclined outwards by an angle, and can be locked on the slideway by using the limited elasticity of the two steel wire suspension arms extended from the hooks, namely the two sliding sleeves can freely slide and adjust on the slideway by pinching, and the sliding sleeves are tightly locked on the slideway by the limited elasticity after being loosened, and even the circular sliding sleeves are difficult to easily rotate; the structure that the two sliding sleeves respectively incline outwards by an angle is applied to a steel wire hanging and pulling type fixing device, and the locking and sliding adjustment effects are also achieved; the hook sliding sleeve can rotate to form structures installed in different directions, and a common hook can be used as a hook on a fixing device (the hook is used in an inverted mode), so that the hook sliding sleeve is convenient to process and convenient for a user; for the self-locking hook of the prismatic slideway, a straight arm hook which extends upwards can be made, or a hook which is hooked upwards is called, the hook arm length of the structure is long, the overcoat, the cap and the like can be easily hung, and the prismatic sliding sleeve and the prismatic slideway can not rotate and have a bidirectional self-locking function, so the arm length of the hook which extends upwards can not rotate due to the weight of the overcoat, and the hook can slide left and right and can be locked to be a dead hook which can not rotate, and the hook is a structure which can not be realized by a common sliding hook; the main components of the hook rack are only a slideway, a self-locking hook and an external fixing device. The three parts can be standardized, so that the machining is simple, and assembly and welding are not needed; the length of the slide way of the hook frame and the number of the hooks can be selected at will to meet the needs of users; the fixing device is also provided with a sliding sleeve (fixed sleeve) structure as the hook, so that the fixing device becomes a standard part on the hook frame and has good interchangeability. Therefore, the fixing mode can be arbitrarily selected. If hanging can be selected, screw fixation can be selected, adhesion can be selected, namely, what kind of user or what place to use, what kind of fixing device is selected to meet the requirements of various users; for shorter hanger brackets, such as hanger brackets used in kitchen cabinet doors and the like, a balanced fixing effect can be achieved by only selecting one fixing device (described above) to fix the hanger bracket in the middle; compared with a circular slide way, the prismatic slide way has large bearing capacity, if the bearing requirement is high, the prismatic slide way can be selected, and if the bearing requirement is relatively low, the circular slide way can be selected; the self-locking hook on the prismatic slideway has a bidirectional locking function, and the circular hook only has a unidirectional self-locking function, so that users with different requirements can select the hook at will; the hook rack composed of the slideway and the self-locking hook can be arranged on any facility with pipes (equivalent to the slideway). For example, the self-locking hook is arranged on a towel rack and can become a part of racks such as the towel rack and the clothes hanger, or a self-locking hook is worn on a pipe of the racks such as the towel rack and the clothes hanger, which is an embodiment of the hook rack; holes for installing pipes (slide ways) on towel racks, clothes hangers and other racks can be used as fixing devices of the hook racks. Therefore, the self-locking hook can be combined with any rack with a pipe, namely a slideway, and the pipe can be used as the slideway by utilizing the fixing device on the rack to be combined into a standard hook rack. The structure of the hook rack has wide application range; the structure that the steel wire arm hinge shaft arranged in the hinge hole on the fixing device is provided with the convex circular arc (the convex circular arc is arranged in the direction of 45 degrees by taking the hinge shaft and the plane of the connecting sleeve as a reference object) is the simplest locking pin device. When the wire arm is balanced in the horizontal direction, the hinge axis protruding out of the circular arc and the hinge hole are not in a compressed relationship; when the steel wire arm swings upwards to a 45-degree angle area, under the action of an external force of lifting by hands, the protruding circular arc of the hinge shaft is compressed and deformed by the hinge hole (the deformation is the largest when the steel wire arm forms a 45-degree angle with the horizontal plane, so the deformation is an area), and when the steel wire arm exceeds the area under the action of the external force and swings to be vertical to the horizontal plane, the protruding circular arc is not pressed by the hinge hole any more, and the steel wire arm stands to lean against the wall. The steel wire arm (upper connecting towel bar) is beyond the circular arc deformation area of the hinge shaft under the action of self gravity, so that the locked pin is firmly locked to stand against the wall. This effect acts as a pin lock wire arm. That is, the effect is that the towel bar connected with the wire arm is stuck on the wall as soon as the towel bar is pressed on the wall. When a person crosses a 45-degree angle area in the operation process, the hand feeling is particularly comfortable under the action of elasticity; when the towel bar is pressed down by hand, the hinge shaft is restored to the original shape, the towel bar is supported by the high point of the slideway under the action of the gravity of the towel bar, and the steel wire arm can extend forwards to lift the towel bar; the connecting sleeve adopts a spring ring structure to form a long sleeve with a full volume, the central line of the long sleeve can be always parallel to the hinge axis, when the towel bar is inserted into the left and right full sleeve type connecting sleeves, the towel bar can be always parallel to the slideway, the distortion phenomenon of the towel bar can not be generated, the towel bar and the slideway can form a parallelogram plane, and the defect that the prior art is easy to distort can be overcome in the folding process.

Detailed Description

The present invention is described in further detail below with reference to the attached drawing figures.

referring to the attached figure 1, the self-locking hook 1 is formed by folding a steel wire into the top end 2 of a hook, then the bottom of the formed double-strand steel wire is folded into the hook to form a hook 1 hooked downwards, the double-strand steel wire extends upwards to form two suspension arms 3 of the hook, the top ends of the two suspension arms 3 are folded into two sliding sleeves 4, and the two sliding sleeves 4 are outwards inclined by about 5 degrees relative to the suspension arms 3 so as to increase the locking force of the two sliding sleeves 4; on the other hand, the V-shaped opening angle of the two suspension arms 3 can be reduced, and the appearance of the self-locking hook 1 is beautified. When the two suspension arms 3 with the distance are held between the two suspension arms, the central line of the sliding sleeve 4 is just coincident with the central line of the slideway 8, and the hole of the sliding sleeve 4 is in movable fit with the slideway 8, so that the sliding sleeve 4 can freely slide on the slideway 8. When two suspension arms 3 with intervals are loosened and pinched, the elastic force of the steel wires of the suspension arms 3 enables the sliding sleeve 4 to restore to an angle about 5 degrees outwards, and the central line of the sliding sleeve 4 deviates from the central line of the slideway 8, so that the sliding sleeve 6 is clamped on the slideway 4 and locked in the left and right directions.

The sliding sleeve 4 can be prismatic, and the prismatic sliding sleeve 4 can not rotate on the prismatic slideway 8, so the prismatic hook 1 of the sliding sleeve 4 is called as a bidirectional self-locking hook.

The sliding sleeve 4 can also be round, the round sliding sleeve 4 can lock the self-locking hook 1 in the axial direction, and the self-locking hook 1 is not easy to rotate under the normal condition by the locking force of the axial direction, but belongs to a one-way self-locking hook.

Referring to the attached figure 2, the self-locking hook 1 is formed by folding a steel wire into a hook end 2, then two steel wires come out to form two relatively long suspension arms 3, the end parts of the two suspension arms 3 are folded into prismatic sliding sleeves 4, and the two prismatic sliding sleeves 4 are inclined outwards by an angle of about 5 degrees. After the sliding sleeve 4 with the relatively long hanging arm is sleeved on the sliding rail 8, the sliding sleeve is locked in two directions of the sliding rail 8, the sliding sleeve can be upwards lifted by 45 degrees due to the fact that the sliding sleeve is not rotated on the prismatic sliding rail 8, the hook 1 is upwards hooked, the length of the hanging arm 3 can be used for hanging large clothes, hats and other objects, the hook is called a big hook, the hook can be combined with the hook 1 in a lower hook mode, the hook is called a small hook, and the big hook and the small hook are combined on the sliding rail 8, so that a user can conveniently and freely select the big hook and the small hook to hang different objects.

Referring to fig. 3, the cross section of the slide 8 may be prismatic or circular. Under the condition that two ports of the slide way 8 are exposed, when the slide way 8 is prismatic, the shape of the pipe plug 5 is matched with the slide way.

The length of the slide way 8 can be selected, and the two slide ways 8 can be connected and combined together through an insert to prolong the length of the slide way 8. The connecting structure of the insert in the slideway 8 can be conveniently carried. For example, the walking stick can be used in business trips and college students' dormitories, and can be disassembled to be carried when walking and used together when being used. The structure is mainly used for fixing devices with fixing hooks 13 and can also be applied to other fixing devices.

The number and the spacing of the self-locking hooks 1 can be selectively arranged on a slideway 8, the slideway 8 is prismatic, namely the self-locking hooks 1 with prismatic sliding sleeves 4 are arranged, and the slideway 8 is circular, namely the self-locking hooks 1 with circular sliding sleeves 4 are arranged. Of course, the slideway 8 can also be selected with other shapes and is matched with the sliding sleeve 4 with the corresponding shape.

The fixing device 7 is a prismatic or circular fixing sleeve 9 folded by a stainless steel plate, and the fixing sleeve 9 is also sleeved on the slideway 8. Except that the slide way 8 is matched with the slide way by itself or is fastened by screws through screw holes. The two stainless steel plates at the middle end (protruding part) of the fixing sleeve 9 form a hinge hole to be matched with the hinge shaft 31 of the dual-wire arm 27, and the movement change of the hinge shaft 31 of the dual-wire arm 27 and the locking pin principle of the hinge hole are described with reference to fig. 11.

Referring to fig. 4, the fixing sleeve 9 has a fixing plate 11 at the rear end thereof and a fixing hole 10 formed therein, and the fixing device 7 can be directly fixed to a fixture by screws. The plastic bonding plate 6 with a large area can be sleeved (the fixing plate 11 is sleeved on the back surface of the bonding plate 6 and also becomes a glue coating surface) for bonding and fixing, and the bonding area is enlarged by utilizing the plastic plate bonding plate 6 to strengthen the firmness of the plastic plate bonding plate.

The fixing device can also be a hole of a hanging device of any frame, for example, a towel rack, a clothes hanger and the like with a rack capable of fixing a pipe (a slide way), and the extended pipe can be used as a slide way to directly install the self-locking hook, namely, the pipe of the rack is the slide way 8 of the invention, or the hook rack of the invention is used as an accessory to be installed in the hole of the towel rack and the clothes hanger to be fixed. The "hole" or connection at its point of attachment is thus a kind of fixing means 7.

The fixing device 7 may also be a hanging type fixing device formed by folding a steel wire, see fig. 5.

Referring to fig. 5, the fixing device 7 of the hook rack is composed of a fixed hook 13 and a fixed sliding sleeve 12, the fixed sliding sleeve 12 is a structure with the same property as the hook sliding sleeve 4, and can slide and lock on the slideway 8 by folding the angle of about 5 degrees outwards, and the fixed sliding sleeve 12 can be prismatic or circular. The fixed hook 13 arranged on the upper surface can be hung on a door or other hung fixed objects to complete the fixation of the hook rack. The hook 1 on the hook rack is hung on the slideway 8 in a reversed way, so that the common hook 1 becomes a fixed hook 13. The reversed hook 1 has wider application, can be directly hung on a pipe of a towel rack and is changed into a row of hooks 1 formed by a hook rack for use, and is very convenient; or can be hung on a suitable plate-type fixed object, such as a backrest of a chair, a cabinet door and other fixed objects. The fixing hook 13 can be made into various shapes and is suitable for being used by fixtures in different occasions. Because the fixed sliding sleeve 12 arranged below the self-locking hook 1 is standard, the hook type fixing device 7 can be replaced aiming at different fixed objects, the selection of a user is facilitated, and the hook rack becomes a universal hook rack.

referring to fig. 6, the fixing device is formed by combining a fixing sleeve (sleeved on the slideway 19) and a sticky plate 22 into a whole and is formed in one step by injection molding. The fixing sleeve is formed by connecting a front fixing sleeve 15 and two rear fixing sleeves 14 on a bonding plate 22, a fixing hole 18 is formed in the bonding plate 22 and used for fixing by using a screw, and the fixing device can be fixed by using glue or a screw, so that a user can select the fixing device conveniently. The ellipse on the fixing device is the trademark position, the area of the back of the trademark is the adhesive coating surface for expanding adhesion, and the redundant area arranged on the fixing sleeve is from the angle of mechanics, namely the fixing sleeve is hung up, so that the reliability of the bearing of the slide way 19 in the fixing sleeve is ensured.

The inner surface of the front fixed sleeve 15 is in a semicircular shape and is matched with a circular slideway 19; the two rear fixing sleeves 14 are respectively arranged at the left side and the right side of the front fixing sleeve 15, and the outer surface (facing outwards) of the rear fixing sleeve 15 is in a semicircular shape, namely two semicircles formed on different sections are added together to form a package for fixing the circular slideway 19. In order to ensure the bearing capacity of the slideway 19, a sheet-shaped reinforcing rib 17 which protrudes outwards is arranged on the front fixing sleeve 15. The reinforcing ribs 17 can also be in a trapezoidal structure, so that the requirement on strength is met, and the effect of good appearance is achieved. The two ends of the circular slideway 19 are provided with petal-type plugs 16 to plug the ports, so that the appearance effect is good. The fixing device is provided with a hinge hole 21.

referring to fig. 7, the adhesive plate 22 on the back of the fixing device of the circular slideway is provided with a front fixing sleeve through hole 20, that is, the front fixing sleeve hole 20 is communicated with the inner surface of the front fixing sleeve 15, so as to draw out the core of the mold (the inner core of the front fixing sleeve 15) from the back when the plastic part is injection molded, and avoid the complicated structure and process caused by the core pulling from the side. As can be seen here, this structure solves three problems: firstly, the width of the fixing sleeve is increased, so that the slide way cannot be twisted due to one surface bearing; secondly, the appearance is beautiful; thirdly, the process is simplified, the cost is reduced, and the quality is ensured.

The sticky board 22 on the back of the fixing device is provided with a groove to form a hinge hole 21, when the sticky board 22 is attached to a wall, the groove becomes a completely closed hinge hole 21, and the position of the hinge hole 21 enables the steel wire arm 26 to be on a horizontal plane when the steel wire arm 26 is lapped on the slideway 19 or other slideways at the highest point. The structural arrangement of the open hinge hole 21 mainly aims to simplify the processing technology of the mold and avoid the complication of a plastic mold due to the arrangement of a side hole on a fixing device; on the other hand, the hinge shaft 21 can be arranged at the final position, so that the phenomenon that the axial center of the fixing sleeve extends outwards for too long distance to be beneficial to the arrangement of the optimal supporting position can be avoided. The groove may be larger than the diameter of the hinge shaft 26 in the front-rear direction, and insertion holes (holes) are formed in both end surfaces, so that the fixing device is not divided into left and right parts, and the processing and selective combination are facilitated. Of course, it is also an embodiment to provide holes on one side and to close them on the other side.

The fixing sleeve of the fixing device is divided into two parts, namely a front fixing sleeve 15 and two rear fixing sleeves 14, the inner face of the front fixing sleeve 15 and the inner faces of the two rear fixing sleeves are staggered with each other, the core of the inner face of the front fixing sleeve is drawn out from the through hole 20 in the back of the bonding plate 22, and the inner faces of the two rear fixing sleeves 14 arranged on the left side and the right side of the front fixing sleeve 15 are exposed on the front plane, so that the die design is facilitated. The hinge hole 21 is formed as a groove which forms the hinge hole 21 in the true sense when the fixing means 22 is fixed to the wall surface, and this is intended to simplify the mold and the manufacturing process, but this simplification presupposes that the structure and function must be optimized, otherwise it is meaningless. The hinge hole 21 is arranged at the rearmost (close to the wall), so that the distance of the slide way 19 extending forwards is shortened, namely, the force arm for hanging the fixed sleeve is shortened, the defect that the strength of a plastic part is not as high as that of a metal is reduced, and the safe and reliable use of the plastic part is ensured. Therefore, the method is a win-win technical measure.

Referring to fig. 8, the slide 19 is secured by two securing means. One or two slide ways 19 may be inserted into the tube of the slide way through a connecting shaft 23 to connect the slide ways 19. In the case of the prior art, this connection may have a phenomenon of sagging at the joint. However, with the fixing device of the present structure, the problem of joint sagging does not occur with the fixing sleeve having the same width as the adhesive plate, which is provided with the front fixing sleeve 15 and the two rear fixing sleeves 14. Because each slide 19 is firmly fixed by the fixing device, the torsion and sagging are not possible. The combination mode is equivalent to that two independent fixing devices are connected together in the middle, each fixing device is fixed with an independent slide way 19, two pipes (slide ways 19) are inserted into the two pipes by a connecting shaft 23 and connected, and the combination mode is only required by one appearance and is equivalent to that the two pipes are mutually provided with a plug.

Referring to fig. 9, the inner surface of the front fixing sleeve 15 is in a V shape and is matched with the circular slideway 8; the two rear fixing sleeves 14 are respectively arranged at the left side and the right side of the front fixing sleeve 15, and the outer surface (facing outwards) of the rear fixing sleeve 15 is in a V shape, namely, a prismatic slideway 8 is wrapped and fixed on different sections. In order to ensure the bearing capacity of the slideway, a sheet-shaped reinforcing rib 17 which protrudes outwards is arranged on the front fixing sleeve 15, and the appearance of the reinforcing rib is changed along with the change of the V-shaped shape of the front fixing sleeve 15. The reinforcing ribs 17 can also be in a trapezoidal structure, so that the requirement on strength is met, and the effect of good appearance is achieved.

The fixing device of the V-shaped slideway is provided with a front fixing sleeve hole 20 on the back side as the circular slideway, namely the front fixing sleeve hole 20 is communicated with the inner surface of the front fixing sleeve 15, so that when a plastic piece is injected, a core of a mould is drawn out from the back, and the problem that the structure and the process are complicated due to the fact that the core is drawn from the side surface is avoided.

The slide 8 is fixed by two fixing means. One or two slide ways 8 can be inserted into the tube of the slide way through a prismatic connecting shaft 23 to connect the slide ways. In the case of the prior art, this connection may have a phenomenon of sagging at the joint. However, with the fixing device of the present structure, the problem of joint sagging does not occur with the fixing sleeve having the same width as the adhesive plate, which is provided with the front fixing sleeve 15 and the two rear fixing sleeves 14. Because each slide 8 is firmly fixed by the fixing device, the torsion and sagging are not possible. This combination corresponds to two separate fastening devices each fastening a separate runner 8. Hanging ring type plugs 5 are arranged at two ends of the prismatic slideway 8 to keep the appearance good.

Referring to fig. 10, the wire arm 25 is formed by folding a hinge shaft 26 formed by folding a wire in the middle, extending the length of the wire arm 25, and then bending a connecting sleeve 24 wound into a spring shape along the hinge shaft 26, wherein the inner diameter of the connecting sleeve 24 is matched with the outer diameter of a towel bar (pipe). The hinge axis 26 forms a plane with the connecting sleeve 24, and the hinge axis 26 is a circular arc protruding outwards and inwards at an angle of 45 degrees with respect to the plane. When the hinge shaft 26 with the curvature is inserted into the hinge hole 21 of the fixing device in the horizontal plane direction, a circle of the protrusion of the hinge shaft 26 is in an undeformed state in the hinge hole 21; when the steel wire arm 25 is lifted upwards by an angle of 45 degrees, the hinge shaft 26 protrudes a circle arc which is larger than the hinge hole 21, the hinge shaft 26 protrudes a circle arc and can pass through the limitation of the hinge hole 21 through deformation, and the deformation can be continued to pass (rotate) under the action of relatively large external force; when the steel wire arm 25 rotates to be vertical to the horizontal plane, namely when leaning against the wall surface, the hinge shaft 26 protrudes a circle arc, the hinge shaft 26 is in a non-deformation state, and the steel wire arm 25 can not make the hinge shaft 26 protrude a circle arc to deform at all only by the action of the gravity of the steel wire arm 25, so that the steel wire arm is locked by the lock pin to lean against the wall surface and can not fall down. This is the desired effect of the latch with the simplest structure, which feels good as if the towel bar is immediately sucked onto the wall as soon as the towel bar is lifted upwards; the force applied to the towel bar by lightly pressing the towel bar (to the 45 degree region) causes the hinge axis 26 to project a circular arc and to deform beyond the elastic deformation barrier, the wire arm 25 falls down and is supported by the slideway 19, and a balanced state is achieved in the horizontal direction, so that the towel bar is kept in a hanging state extending forwards. It is noted that the deformation of the hinge axis 26 through a circular arc is a gradual deformation and gradual return deformation, with the maximum deformation being at a 45 angle to the horizontal of the towel bar (wire arm). Because the deformation is an area, the towel bar can be attached to a wall.

Referring to fig. 11, the wire arm 27 is formed by extending a small section of wire at the two ends of a wire after the middle of the wire is first folded into a hinge shaft 31, and then bending the wire at 45 degrees (because the hinge hole is located on the center line of the prismatic slideway and is parallel to the highest point of the prismatic slideway after being bent at 45 degrees) forward in the horizontal direction to form a double wire arm 27, the ends of the two wires of the double wire arm 27 are folded into a connecting sleeve 29 connected with the towel bar, and the connecting sleeve 29 is formed by spring-shaped sleeves formed by respectively winding the two wires inwards (wherein the wire at one end is a circular ring). The towel bar is inserted into the spring-like sleeves of the left and right connecting sleeves 29. The fixing device is formed by folding two stainless steel strips, a gap is formed between the two stainless steel strips in the middle, the length of the gap is controlled by a fixing screw (refer to figures 3 and 4), and a hinge hole is formed by the gap at the front end of the screw. The hinge shaft 31 is mounted in a hinge hole formed in the front slit of the fastening screw fixture in a hinged relationship. When the wire arm 27 swings forwards and can be lapped on the prismatic slideway 8, the wire arm 27 extends forwards in the horizontal direction to reach a balanced state, and then the towel bar can hang towels and other articles. When the towel bar is not in use, the wire arm 27 swings upwards and stands up against the wall for the folding function.

The hinge axis 31 between the two wire arms 27 protrudes outward in a circular arc shape (corresponding to a 45-degree angle on the plane formed by the wire arms 27 and the connecting sleeve 29). The structure ensures that when the wire arm 27 is balanced in the horizontal direction, the protruding circular arc shape of the hinge shaft 31 is not changed in the hinge hole; when the wire arm 27 swings upward to 45 degrees, the protruding circular arc of the hinge shaft 31 is compressed by the restriction of the hinge hole, and a force for restricting the continuous rotation is generated. The hinge shaft 31 resumes a convex circular arc shape in the hinge hole when the suspension arm swings upward to a 90 degree angle. Thus, when the folding wire arm 27 is swung up against the wall, the wire arm 27 stands against the wall perpendicular to the horizontal plane. This elastic deformation change of the outwardly projecting circular arc of the hinge axis 31 serves as a locking of the wire arm 27, i.e. when the wire arm 27 stands, it cannot go over the deformation zone of the projecting circular arc in the hinge hole without the action of external force and cannot fall down by itself. The operation is particularly convenient, the towel bar can be attached to the wall only by pressing the towel bar upwards with hands, and particularly, the hand feeling is particularly comfortable as the magnet on the wall under the action of the elastic area during the operation of people.

The middle positions of two steel wires of the steel wire arm 27 are folded into a downward concave semicircle 28, a second towel bar can be placed in the semicircle 28, the number of the towel bars is increased, and a certain density is formed, so that the object placing rack for placing objects such as towels can be placed on the object placing rack.
