All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to the attached drawings 1-5, a soft film installation structure comprises a filler strip keel 1 and a filler strip 2, wherein the filler strip keel 1 and the filler strip 2 are both linear structures, the filler strip keel 1 is made of alloy materials and is fixedly connected with a wall body through screws in general, the filler strip keel is an integrally formed structure to increase structural strength, the filler strip 2 is made of PVC materials and is low in cost and widely used in the decoration field, the filler strip 1 has good elasticity and can play a flame retardant role, the notch of the groove 11 faces upwards, the filler strip 2 is matched with the groove 11 to clamp a soft film 3, two first pressing structures 12 which are mutually inclined are arranged in the groove 11, the first pressing structures 12 have certain distances from the groove bottom and the notch of the groove 11, and an assembly space 16 for accommodating the filler strip 2 is formed between the two first pressing structures 12, the tampon 2 is completely covered and wrapped by the soft membrane 3 and clamps and fixes the soft membrane 3 with the two first pressing structures 12, a narrow opening 17 and a wide opening 18 are defined between the two corresponding ends of the two first pressing structures 12, and the soft membrane 3 enters the assembly space 16 from the narrow opening 17.

In this embodiment, the filler strip keel 1 further has a fixing plate which is used for being connected with a wall body and is vertically arranged, the fixing plate is connected with one end of the groove 11 through a horizontal transition connecting plate, and a part of the fixing plate, the transition connecting plate and one of groove walls forming the groove 11 jointly form an edge folding structure, so that the wall board can be inserted into the edge folding structure to be folded.

The clamping of the soft membrane 3 by the tampon 2 and the first pressing structure 12 allows the soft membrane 3 to be well fixed for a stable connection. After the installation, the mantle 3 can be to the notch direction slippage because of self gravity, drive the tang 17 removal that stuff 2 is injectd to two first oppression structures 12 at this in-process for stuff 2 receives the further extrusion of first oppression structure 12, increased the clamping-force between stuff 2 and the first oppression structure 12, thereby make mantle 3 by further clamp, and then not only can prevent the slippage of mantle 3, can also form the effect that mantle 3 pulled tighter more.

In addition, the mounted tampon 2 is completely wrapped by the soft membrane 3, and compared with a comparison document, the aging speed of the tampon 2 can be greatly reduced, and even after the long-term use, the tampon 2 still has good elasticity, can provide enough supporting force to be matched with the first pressing structure 12 to clamp the soft membrane 3, so that the soft membrane 3 is prevented from slipping.

Referring to fig. 4, the furring strip keel 1 further has an inclined connection portion 13 connected to the first pressing structure 12, and a horizontal connection portion 14 connected to the groove edge of the groove 11, wherein the inclined connection portion 13 is connected to the horizontal connection portion 14, and the inclined direction of the inclined connection portion 13 is the same as that of the corresponding first pressing structure 12. The plug-in space 15 is formed between the two inclined connecting parts 13, and the connecting parts of the two horizontal connecting parts 14 and the inclined connecting parts 13 together form a plug-in port 151 for the plug strip 2 to pass through, namely the real notch of the groove 11, which aims to reduce the size of the real notch of the groove 11 as much as possible, firstly, the air plugged into the space 15 is difficult to circulate with the outside air, and a stable environment is formed in the plug-in space 15, so that the aging speed of the plug strip 2 is further reduced, secondly, the dust entering the plug-in space 15 is reduced, and further, the deposition of the dust on the surface of the soft membrane 3 and the gap between the soft membrane 3 and the first pressing structure 12 is reduced, because the substances forming the dust are complex, on the acid and alkali, acid radical ions are sometimes provided in an acid form, metal ions are sometimes provided in an alkali form, and the specific surface area of the dust is large, the dust accumulated on the surface of the soft membrane 3 is wetted to form a good chemical reaction condition when the humidity is high, the surface of the soft membrane 3 is corroded, the stability of the soft membrane 3 is affected, the soft membrane 3 is not beneficial to being stably clamped after long-time use, large particles exist in the dust in the particle size, after the dust enters between the soft membrane 3 and the first pressing structure 12, the contact area between the soft membrane 3 and the first pressing structure 12 is reduced, the friction force is reduced, meanwhile, the static friction force between the soft membrane 3 and the first pressing structure 12 is converted into the rolling friction between the soft membrane 3, large-particle dust and the first pressing structure 12, the friction force is further reduced, and in combination with the characteristic that the dust is easy to absorb water, the moisture further serves as a lubricant, the friction force is further reduced, so that the soft membrane 3 is easy to slip off, and therefore, the size of a real notch of the groove 11 needs to be reduced as much as possible, the dust is reduced to influence the stable clamping of the soft film 3.

In this embodiment, the inclined connection portion 13 is connected to one end of the first pressing structure 12 forming the wide opening 18, so that firstly, deformation of the first pressing structure 12 caused by extrusion is restricted by the inclined connection portion 13, and even if the first pressing structure 12 is subjected to large deformation, a narrow opening end of the first pressing structure 12 is directly contacted with the inclined connection portion 13 and does not exceed the range of elastic deformation, so that when the tampon 2 enters from the narrow opening 17, the support of the inclined connection portion 13 on the first pressing structure 12 is not damaged; secondly, the inclined connecting part 13 and the first pressing structure 12 form an ash deposition groove 19 for depositing ash, dust is particles suspended in air and does brownian motion in the air, so the dust is uniformly distributed in the plugging space 15, when the dust is deposited, the narrow opening end of the first pressing structure 12 separates an ash deposition area, and the ash deposition groove 19 plays a role of reducing the dust entering the plugging space 15 to be accumulated to the narrow opening 17 as much as possible, so that the dust at the narrow opening 17 is less, and the slipping of the soft membrane 3 after long-time use is further prevented.

In this embodiment, the outer surface of the junction of the inclined connecting portion 13 and the horizontal connecting portion 14 is in smooth transition, and the soft film 3 is attached to the soft film after being tensioned, so that the soft film 3 is prevented from being scraped to form burrs in the installation process, and the appearance is not affected.

Referring to fig. 5, the surfaces of the two first pressing structures 12 clamping the soft membrane are provided with saw-toothed protrusions 121 for increasing the friction force with the soft membrane 3. Specifically, the protrusion 121 has three circularly continuous surfaces, namely a first slope 1211 close to the narrow opening 17, a second slope 1213 close to the wide opening 18, and a second curved surface 1212 connecting the first slope 1211 and the second slope 1213, and the deviation angle of the first slope 1211 is smaller than that of the second slope 1213 relative to the surface for holding the soft membrane, when the soft membrane 3 is wrapped by the tampon 2 and is inserted, the resistance is smaller because the deviation angle of the first slope 1211 is smaller, the soft membrane 3 and the tampon 2 are more easily inserted, and when the soft membrane 3 slips, the soft membrane 3 is less likely to slip because the deviation angle of the second slope 1213 is larger.

Referring to fig. 2 and 3, the tampon 2 includes two elastic structures 21 integrally formed and forming a break angle with each other, the elastic structures 21 abut against the corresponding first pressing structures 12, during installation, a user wraps the tampon 2 with the flexible film 3 and folds the tampon 2 by applying pressure in the horizontal direction, after the tampon 2 is plugged in, the two elastic structures 21 abut against the corresponding first pressing structures 12 by restoring elastic deformation and expanding, so as to cooperate with the first pressing structures 12 to clamp the flexible film 3. Compared with other structures, the folding structure can be better extruded and is easy to be plugged into the groove 11, and after the folding structure is unfolded due to the recovery of elastic deformation, the folding structure can occupy larger space and provide enough support for clamping the soft membrane 3.

The thickness of the tampon 2 becomes thinner from the folding angle to the two ends, so that after the tampon 2 is folded, the width of the folding angle of the two tampon 2 is larger than the width formed by the two ends. The width formed by the two ends can be easily inserted into the narrow opening 17 of the first pressing structure 12 when inserting into the groove 11.

Two the surface that elastic construction 21 is relative has the first curved surface 211 of hunch-up the stuff back 2 is used for pressing from both sides tightly when being folded the mantle 3, because stuff back 2 can receive powerful extrusion in the process of stuffing into, consequently stuff back 2 is folding back, can prevent that mantle 3 from sliding relative stuff back 2, and the inside dog-ear department of stuff back 2 is formed with a closed space who holds mantle 3 bending part simultaneously for mantle 3 can not form the crease.

The surface that elastic construction 21 faced first oppression structure 12 is bellied curved surface, because in the in-process that stuff 2 was pull to mantle 3, according to the size of traction force, two the contained angle that forms between the elastic construction 21 can change, simultaneously the inclination of first oppression structure 12 also can change, consequently elastic construction 21 faces the change of various angles can be adapted to the curved surface of first oppression structure 12 for elastic construction 21 has great area of contact with first oppression structure 12 all the time, thereby prevents the slippage of mantle 3.

The mounting method of the soft film mounting structure comprises the following steps:

s1: fixing the filler strip keel 1 on a wall body;

s2: completely cover-wrapping the soft film 3 on the tampon 2;

s3: folding the stopper strip 2 to clamp the soft film 3;

s4: the stopper 2 and the soft membrane 3 folded in the step S3 are inserted into the assembling space 16, and the stopper 2 cooperates with the first pressing structure 12 to clamp the soft membrane 3 under the action of elastic force.

Firstly, the elastic line of the wall surface is well bounced on the wall surface, the filler strip keel 1 is aligned with the elastic line of the wall surface, then the filler strip keel 1 is fixed with the wall body through a screw to ensure that the filler strip keel 1 is in a preset position, then irregular and redundant soft films 3 are cut off, the cork strips 2 are completely covered and wrapped by the soft films 3, then the cork strips 2 are folded to clamp the soft films 3, and the fact that the soft films 3 are soft needs to be noticed, the flexible film 3, which is covered between the opposite surfaces of the two elastic structures 21, is easily creased during folding, making it possible to fold the flexible film 3 after it has been gripped by the tampon 2, so that, during folding, a thin rod can be used, the soft film 3 is propped against the folding corner of the tampon 2, so that the soft film 3 is tightly attached to the surface of the tampon 2, then the soft film 3 and the thin rod are clamped together, and then the thin rod is drawn out, so that the wrinkles generated in the folding process of the soft film 3 can be reduced. In the process of plugging the assembling space 16, because the narrow opening 17 is far away from the notch, at the beginning, the narrow opening end of the first pressing structure 12 interferes with the tampon 2, the narrow opening end of the first pressing structure 12 extrudes two ends of the tampon 2, and then the tampon 2 is pushed into the narrow opening 17 direction through the notch until the tampon 2 is completely positioned in the assembling space 16.

In the actual installation, the first time the soft membrane 3 is not installed in place, the soft membrane 3 is folded, the clamping position of the soft membrane 3 needs to be adjusted again, in this embodiment, only the traction of the soft membrane 3 on the tampon 2 needs to be loosened, because the wide-mouth end of the first compression structure 12 is still at a certain height from the groove bottom of the groove 11, the tampon 2 can be further pressed towards the groove bottom of the groove 11, so that the tampon 2 is separated from the first compression structure 12, the soft membrane 3 can freely slide between the first compression structure 12 and the tampon 2, the proper clamping position of the soft membrane 3 can be adjusted, and after the adjustment is completed, the tampon 2 is driven to be clamped into the assembly space again by lifting the two sides of the soft membrane 3 wrapping the tampon 2 upwards together. Compare in the comparison file, this embodiment need not take out the stuff when the adjustment again, and then the step when repeated card, has avoided stuff 2 to be folded repeatedly, leads to stuff 2 to lose the elastic deformation ability when initial. In addition, during adjustment, if the soft membrane 3 and the tampon 2 are completely separated from the groove 11, a user cannot easily judge the clamping position before adjustment, so that the clamping position after adjustment cannot be determined.

Example two

The difference between this embodiment and the first embodiment is that a connecting arm 41 with one end connected to a groove wall is further symmetrically disposed in the groove 11, one side of the connecting arm 41 abuts against one end of the first pressing structure 12 forming the wide opening 18, one end of the connecting arm 41 away from the groove wall of the groove 11 is connected to a second pressing structure 42 forming a bevel relationship with the connecting arm 41, the second pressing structure 42 is disposed corresponding to the first pressing structure 12, a surface of the second pressing structure 42 opposite to the first pressing structure 12 has a second sawtooth-shaped protrusion, and a structure of the second protrusion is the same as the protrusion, which is not described herein again. In this embodiment, when the tampon 2 and the flexible membrane 3 are inserted into the assembly space 16, the first pressing structure 12 and the inclined connecting portion 13 are deformed under force, so as to press the connecting arm 41 to deform, and it should be noted that the connecting point of the connecting arm 41 and the groove wall of the groove 11 should be higher than the end of the second pressing structure 42 away from the connecting arm 41, so as to prevent the two second pressing structures 42 from interfering with each other when the two pressing structures 42 are deformed under force. The tampon 2 with after the installation of mantle 3 is accomplished, second oppression structure 42 can press from both sides tightly with the cooperation of first oppression structure 12 elasticity structure 21 further prevents the slippage of mantle 3, makes the mantle 3 that is located between two elasticity structures 21 also can hug closely tampon 2 simultaneously, avoids locating after the installation that two elasticity structures 21 are relative surface and air contact, restriction tampon 2's oxidation.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments can be modified, or some technical features can be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
