And the clamping block 121 is slightly inclined from top to bottom to outside relative to the connecting seat 11, so that difficulty in separating one end of the clamping block 121 with the hook part from the clamping hole 111 can be increased, and connection stability of the clamping block 121 and the clamping hole 111 can be improved.

Referring to fig. 2 and 3, the fixing cover 12 and the latch 121 may be made of plastic with elastic deformation, the adjacent side walls of the two latching holes 111 are provided with protrusions 112 protruding toward the central axis of the corresponding latching holes 111, and the distance between the protrusions 112 and the opposite side walls of the latching holes 111 is not greater than the width of the lead angle of the latch 121. The distance between the ends of the two clamping blocks 121 with the hook parts is larger than the distance between the two clamping holes 111; when the clamping block 121 passes through the clamping hole 111 and is clamped on the connecting seat 11, the hook part is positioned on one side of the connecting seat 11 far away from the fixed cover 12 and is abutted against the connecting seat 11; and the protrusion 112 can further limit the latch 121 to be separated from the latch hole 111 by engaging with the hook, so that the fixing cover 12 is fixedly connected with the connecting seat 11. In this embodiment, the fixing cover 12, the latch 121 and the hook are integrally formed by injection molding of a resin material.

Referring to fig. 1 and 2, the upper surface of the connecting seat 11 is provided with a clamping column 113 protruding towards the fixing cover 12, and the upper part of the clamping column 113 is a cone. The clamping column 113 is located between the two clamping holes 111, and is used for making the middle part of the lifting belt 3 located between the fixing cover 12 and the connecting seat 11 more firmly. The side wall of the fixing cover 12 is provided with a through hole for the pull-up belt 3 to pass through, and the upper side of the through hole is provided with a convex tooth 122 protruding downwards. The convex teeth 122 cooperate with the clamping posts 113 to further clamp and fix the middle part of the lifting belt 3. When in use, the lifting belt 3 can be an annular belt, and the middle part of the lifting belt is overlapped up and down and is positioned between the fixed cover 12 and the connecting seat 11.

Referring to fig. 3 and 4, two opposite sides of the connecting base 11 are respectively provided with a catching piece 13, each catching piece 13 is provided with a drawing hook groove 131, and the drawing hook groove 131 is located at the lower portion of the connecting base 11. In this embodiment, the connecting seat 11, the protrusion 112, the clip 13 and the clamping column 113 are made of resin material by integral injection molding.

Referring to fig. 1 and 4, each of the towing hook grooves 131 is provided with a notch; the notches of the two towing hook grooves 131 are oppositely arranged. Each traction assembly 21 includes an annular collar member 211; the collar member 211 has a pull out detent 2111 on one side. The traction clamping rod 2111 is clamped in the traction hook groove 131 from the interval between the two clamping pieces 13 and the notch of the traction hook groove 131 in sequence and is hinged with the clamping pieces 13.

Referring to fig. 4, when the fixing cover 12 is fastened to the upper surface of the connecting base 11, the lower end of the latch 121 passes through the fastening hole 111 and is located between the two fastening pieces 13, the minimum distance between the latch 121 and the fastening piece 13 is smaller than the outer diameter of the traction clamping rod 2111, that is, the latch 121 located between the two fastening pieces 13 limits the traction clamping rod 2111 to be separated from the fastening piece 13 through the interval between the two fastening pieces 13, so that the connection stability of the assembled slack adjuster is improved.

Referring to fig. 4, the side of the collar member 211 remote from the distraction rod 2111 is a spacer 2112, and the collar member 211 has an annular ring between the distraction rod 2111 and the spacer 2112. A pulling eye 212 is connected to the side of the collar piece 211 close to the spacer bar 2112, the pulling eye 212 being located on the upper side of the spacer bar 2112, the pulling eye 212 having a pulling eye through which the end of the pull tape 3 is passed. In use, the end of the lifting strap 3 is positioned through the pulling hole of the pulling eye piece 212 on the side of the pulling assembly 21 remote from the attachment socket 11. The collar member 211 and the pull collar member 212 are integrally injection-molded from a resin material.

Referring to fig. 1 and 4, the sliding assembly 22 divides the annular hole of the loop member 211 into two belt holes 2113 through which the shoelace 4 is threaded; two band holes 2113 are located between the spacer bar 2112 and the distraction clip bar 2111.

When in use, the end part of the shoelace 4 firstly passes through the lace hole 2113 close to the traction clamping rod 2111 from the lower part of the lantern ring piece 211 upwards; and then passes around the sliding component 22 and passes through the band hole 2113 near the spacing rod 2112 from the upper part of the ring component 211 downwards, so that one end of the outer belt segment 42 of the shoelace 4 near the elastic middle section 41 is pressed between the sliding component 22 and the spacing rod 2112, and the other end of the outer belt segment 42 is positioned at the outer side of the traction component 21.

Referring to fig. 2 and 4, glide assembly 22 includes two glide members 221 and an outwardly pushing resilient member 222; the sliding member 221 has a sliding hole 2211 in the middle for the collar member 211 to pass through, that is, the sliding member 221 has an annular structure. The two sides of the outward pushing elastic piece 222 are both provided with a connecting block 2221 clamped in the sliding hole 2211, and the outward pushing elastic piece 222 is positioned between the two sliding pieces 221 through the connecting block 2221; pushing out spring 222 normally forces slides 221 to move away from each other.

During assembly, one side of the collar member 211, which is provided with the traction clamping rod 2111, penetrates through the two sliding members 221, and then the outward-pushing elastic member 222 is firmly connected between the two sliding members 221 through the connecting block 2221, so that the two sliding members 221 reduce the aperture of the two holes 2113, and the shoelace 4 passing through the holes 2113 is clamped by the sliding members 221 and the collar member 211.

Referring to fig. 4, the side of glide 221 above collar member 211 is an upper slide bar 2212. In this embodiment, the middle portion of the upper slide bar 2212 is recessed into the annular hole, such that the upper surface of the upper slide bar 2212 is recessed, and the lower surface of the upper slide bar 2212 is recessed toward the sliding hole 2211. When the shoelace 4 passes by the sliding components 22, the shoelace 4 can be abutted against the concave part of the upper sliding rod 2212, so that the phenomenon that the shoelace 4 slides out of the sliding components 22 is reduced. The upper sliding rod 2212 is concave downwards to the sliding hole 2211, so that the distance between the upper part and the lower part of the sliding hole 2211 can be reduced; when the ring member 211 is inserted into the sliding hole 2211, the concave portion of the upper slide bar 2212 can be partially located in the ring member 211, thereby increasing the difficulty of separating the sliding member 221 inserted into the ring member 211 from the ring member 211. Meanwhile, the connecting block 2221 of the outward pushing elastic member 222 can be stably clamped in the sliding hole 2211.

Referring to fig. 2 and 4, in the present embodiment, the outward pushing elastic member 222 includes two V-shaped elastic pieces 2222 stacked one above another, a tip of the upper V-shaped elastic piece 2222 faces upward, and a tip of the lower V-shaped elastic piece 2222 faces downward. The two sides of each V-shaped elastic sheet 2222 are provided with the connecting blocks 2221, so that the upper and lower V-shaped elastic sheets 2222 can be conveniently stacked, and the connecting blocks 2221 on the same side of the two V-shaped elastic sheets 2222 are matched with each other and fixedly clamped in the sliding holes 2211. The outward pushing elastic member 222 is made of an elastic material, and the sliding member 221 has elasticity, and the elastic performance of the outward pushing elastic member 222 is greater than that of the sliding member 221. In this embodiment, the V-shaped resilient tab 2222 may be made of steel. The sliding member 221 may be made of a resin material by injection molding.

After the shoe is adjusted by the shoelace 4, the outward pushing elastic part 222 of the sliding assembly 22 pushes the two sliding parts 221 to move away from each other, and the aperture of the two belt holes 2113 is reduced, so that the middle elastic part 41 is clamped between the clamping part 13 and the sliding part 221, or the outer belt section 42 is clamped between the spacing rod 2112 and the sliding part 221. Therefore, the shoelace 4 is limited to move relative to the tightness adjusting device, the length change of the middle tightness section 41 is reduced, and the adjustable range of the shoe is stable.

The embodiment of the application discloses an elasticity adjusting device of shoelace.

Referring to fig. 2 and 5, the difference from embodiment 1 is that the structure of the outward pushing elastic member 222 is different from that of embodiment 1. In this embodiment, the outward pushing elastic member 222 is an elastic body having a rectangular longitudinal section; the outward pushing elastic member 222 may be made of rubber, silica gel, or a bellows section with an internal spring, which has a material or structure with a flexible elastic function. The two sides of the outward pushing elastic member 222 are also provided with a connecting block 2221 clamped in the sliding hole 2211, and the outward pushing elastic member 222 is located between the two sliding members 221 through the connecting block 2221. The upper surface of the connecting block 2221 is provided with a connecting block concave portion for the upper sliding rod 2212 to be embedded in. The outward pushing elastic piece 222 is firmly clamped with the connecting block 2221 in the sliding hole 2211 through the connecting block recess and the upper sliding rod 2212.

Referring to fig. 6 and 7, the traction mechanism 2 of the present embodiment further includes a limiting component 23 according to embodiment 1. The limiting member 23 is connected between the two pulling members 21 or between the pulling members 21 and the connecting base 11 for forcing the two pulling members 21 to be disposed obliquely downward with respect to the connecting base 11.

The limiting member 231 is disposed on the collar member 211 and is located on a side of the draw bail 2111 adjacent to the glide assembly 22. A restricting elastic member 232 is connected between the restricting members 231 of the different collar members 211.

Referring to fig. 6 and 7, in the present embodiment, the portion of the collar member 211 passing through the sliding member 221 is a collar rod segment 2114, and the number of the collar rod segments 2114 is two, and both the collar rod segments 2114 are located between the traction card rod 2111 and the spacing rod 2112. The outer wall of each thimble rod section 2114 is provided with a limiting groove 2115, the limiting groove 2115 is close to the traction card rod 2111, and the lower side wall of the limiting groove 2115 is a through opening. One end of the limiting member 231 is fixed at the bottom of the limiting groove 2115, so that the limiting member 231 is positioned between the traction clamping rod 2111 and the sliding component 22. The restricting member 231 has a convex cap 233 at an end thereof remote from the bottom of the restricting groove 2115, the convex cap 233 having an outer diameter larger than that of the restricting member 231, and the convex cap 233 having an outer diameter smaller than the width of the restricting groove 2115. The convex cap 233 is not exposed out of the limiting groove 2115, so as to reduce the influence on the penetration of the collar member 211 into the sliding member 221.

The elastic member 232 is a string having elasticity such as a rubber string or an elastic string. In this embodiment, there are two limiting elastic members 232, and each limiting elastic member 232 passes through the limiting groove 2115 and is sleeved on the limiting member 231 of the two sets of ring members 211. Namely, the two elastic limiting members 232 are connected with the two traction assemblies 21 and arranged in parallel; or two elastic restraining members 232 are connected to the two traction assemblies 21 and arranged crosswise. In this embodiment, the two elastic limiting members 232 are disposed in parallel.

Referring to fig. 6 and 8, in order to further improve the movement of the shoelace 7 relative to the slack adjuster due to the free movement of the shoelace 4, when the pulling member 21 is inclined downward relative to the connecting base 11, the spacer 2112 closest to the outer surface of the shoe may be further provided with a gravity ring 238 having a protrusion 239.

Referring to fig. 8, in particular, a concave ring groove 2117 for the gravity ring 238 to clamp is recessed in the middle of the spacer bar 2112; the gravity ring 238 can freely rotate around the axis of the spacing rod 2112, the outer diameter of the gravity ring 238 is not smaller than the diameter of the spacing rod 2112, one side of the gravity ring 238 is provided with a notch 2381 matched with the middle part of the spacing rod 2112, and the gravity ring 238 can be smoothly clamped and sleeved on the spacing rod 2112 through the notch 2381. A balancing weight 2382 is arranged in the gravity ring piece 238, so that the balancing weight 2382 is normally positioned below the axis of the spacing rod 2112; the outer wall of the gravity ring 238 is provided with a spur 239; the spur 239 is fixed in position relative to the weight 2382, and the spur 239 is normally located on the side of the gravity ring 238 adjacent to the aperture 2113. In this embodiment, the spur 238 is disposed just opposite the notch 2381.

The implementation principle of the tightness adjusting device of the shoelace in the embodiment of the application is as follows:

referring to fig. 1 and 6, under the stretching action of the elastic limiting element 232, the loop element 211 can rotate around the traction hook slot 131 to incline downwards in the normal state of one side of the loop element 211 away from the connecting seat 11, so that the tightness adjusting device can be integrally attached to the outer surface of the shoe, the outer belt section 42 of the shoelace 4 can be pressed between the traction assembly 21 and the outer surface of the shoe, and the risk of movement of the shoelace 4 relative to the tightness adjusting device caused by free shaking of the shoelace 4 can be reduced.

Referring to fig. 9, after the shoelace 4 is adjusted in position relative to the slack adjuster, the spacing rods 2112 of the loop member 211 are normally close to the outer surface of the shoe and abut against the shoelace 4 under the action of the restriction member 23; meanwhile, the gravity ring 238 sleeved on the spacing rod 2112 is gravity-downward in a normal state, so that the spurs 239 are normally abutted against the shoelace 4. At this time, if the free end of the shoelace 4 swings and the end of the shoelace 4 moves towards the lace holes 2113, the barbs 239 will be tied into the shoelace 4 to restrict the movement of the shoelace 4; if the free end of the shoelace 4 shakes to cause the end of the shoelace 4 to move away from the tightness adjusting device, the burs 239 will also be tied into the shoelace 4, and further reduce the gap between the traction assembly 21 and the outer surface of the shoe, and increase the difficulty of moving the shoelace 4; thereby further improving the risk of movement of the shoelace 4 relative to the slack adjuster as a result of the shoelace 4 freely swaying.

Referring to fig. 10, when the tightness adjusting device needs to be moved toward the end of the shoelace 4, the pulling assembly 21 can be pulled by the pulling strip 3, so that the pulling assembly 21 is tilted upward relative to the connecting seat 11, the distance between the pulling assembly 21 and the upper surface of the shoe is increased, the protruding thorns 239 are arranged toward the holes 2113, and when the free end of the shoelace 4 moves toward the middle tightness section relative to the tightness adjusting device, the gravity ring 238 can be driven to rotate, so that the shoelace 4 can be separated from the protruding thorns 239, and the positions of the shoelace 4 and the tightness adjusting device can be smoothly adjusted.

Referring to fig. 11, when the tightness adjusting device needs to be moved away from the end of the shoelace 4, the two lifting straps 3 can be pulled away from each other to make the traction assembly 21 approach to the same plane with respect to the connecting base 11, so as to increase the distance between the traction assembly 21 and the upper surface of the shoe; at this time, the end of the shoelace 4 is pulled to drive the gravity ring 238 to rotate around the axis of the spacing rod 2112, so that the shoelace 4 is separated from the spurs 239, and the positions of the shoelace 4 and the tightness adjusting device can be smoothly adjusted.

Example 4

The embodiment of the application discloses an elasticity adjusting device of shoelace.

Referring to fig. 12 and 13, based on embodiment 3, the embodiment of the present application is different from embodiment 3 in that the structure of the restricting member 23 is different.

In this embodiment, the limiting member 231 is an annular member sleeved on the outer periphery of the collar member 211, and the limiting member 231 is located between the sliding assembly 22 and the traction clamping rod 2111; each collar member 211 has a limiting member 231; the limiting elastic member 232 is located below the connecting seat 11, and the limiting elastic member 232 is located between the two limiting members 231 and connected to the two limiting members 231 one by one.

The limiting elastic member 232 may be fixedly connected to the two limiting members 231 at the position below the collar member 211, or may be connected to the two limiting members 231 in a snap-fit manner. In this embodiment, the limiting member 231 and the limiting elastic member 232 are connected in a snap-fit manner.

Specifically, the two sides of the elastic limiting element 232 are respectively provided with a hook 234 for the limiting element 231 to penetrate through, and the hooks 234 are connected to one side of the limiting element 231 close to the upper surface of the shoe. The limiting elastic member can be made of elastic materials such as rubber or silica gel. Thereby limiting the elastic member 232 to pull the two limiting members 231 towards each other, and bringing the side of the collar member 211 away from the connecting member to incline downwards.

Example 5

This embodiment discloses an elasticity adjusting device of shoelace.

Referring to fig. 14 and 15, the present embodiment is different from embodiment 3 or 4 in that the structure of the restricting member 23 is different based on embodiment 3 or 4.

The limiting component 23 comprises a limiting elastic column 235 which is convexly arranged on the peripheral wall of the traction clamping rod 2111; the included angle between the normal axial direction of the limiting elastic column 235 and the length direction of the ring-shaped piece 211 is an acute angle; the side of the limiting elastic column 235 far away from the traction clamping rod 2111 is provided with a fixing clamping part 236. The fixing clip 236 is provided with a embedding portion 237 protruding from the outer wall of the collar member 211.

A clamping groove 132 for clamping the fixing clamping part 236 is concavely arranged on the inner wall of the traction hook groove 131, and the clamping groove 132 is positioned at the lower part of the traction hook groove 131; the retainer clip portion 236 is normally located within the clip slot 132.

A caulking groove 133 is arranged on the side wall of the clamping groove 132 far away from the notch of the traction hook groove 131; the insertion groove 133 is for inserting the insertion portion 237. The fixing clip part 236 may be made of a material having a smaller elasticity than the restricting elastic pillar 235, for example, the restricting elastic pillar 235 is made of a high elastic rubber material, and the fixing clip part 236 is made of a plastic material. Thus, when the elastic limiting post 235 deforms along with the rotation of the traction locking bar 2111, the fixed locking portion 236 can be relatively stably connected to the locking slot 132. The fixing clip portion 236 and the clip groove 132 can be further connected firmly by the embedding portion 237 and the embedding groove 133.

The limiting elastic column 235 and the fixing clamping portion 236 can also be used for limiting the traction clamping rod 2111 to be stably positioned in the traction hook groove 131, so that the effect of reducing the risk that the traction clamping rod 2111 is separated from the clamping piece 13 is achieved.

Referring to fig. 15 and 16, in the present embodiment, the number of the limiting elastic columns 235 may be one or multiple, and the number of the slots 132 is the same as the number of the limiting elastic columns 235. The number of the limiting elastic columns 235 in this embodiment is three. The three limiting elastic columns 235 can be arranged side by side along the axial direction of the traction clamping rod 2111 and are positioned on the peripheral wall of the traction clamping rod 2111.

The elastic limit posts 235 and the fixing clip portions 236 cooperate with the clip slots 132 to force the traction clip bar 2111 to drive the collar member 211 to rotate downward in a normal state, so as to achieve the effect of enabling the traction assembly 21 to be inclined downward in a normal state away from one side of the connecting member.

When the pulling assembly 21 is pulled by the pulling belt 3 to rotate upwards or horizontally, one end of the elastic limiting column 235 is connected to the clamping groove 132 along with the fixing clamping part 236, and the other end rotates along with the pulling clamping rod 2111; at this time, the elastic limiting column 235 is elastically deformed, and the elastic limiting column 235 partially abuts against the outer peripheral wall of the traction clamping bar 2111.

Referring to fig. 15 and 16, in order to improve the efficiency of the elastic limit column 235 driving the traction card bar 2111 to return, an avoidance groove 2116 for winding the elastic limit column 235 may be further disposed on the side of the traction card bar 2111 away from the collar member 211, and the elastic limit column 235 is located on one side of the avoidance groove 2116. The number of the avoiding grooves 2116 is consistent with that of the limiting elastic columns 235. That is, when the pulling assembly 21 rotates relative to the connecting seat 11, the elastic limiting column 235 abuts against the escape groove 2116, and the elastic limiting column 235 is clamped between the pulling rod 2111 and the pulling hook groove 131.

The restricting members 23 of embodiment 5, embodiment 3 or embodiment 4 may also be used in combination. For example, the slack adjuster of the present application may have two kinds of restricting units 23 in the embodiments of the present application and embodiment 3, or the slack adjuster of the present application may have two kinds of restricting units 23 in the embodiments of the present application and embodiment 4, or the slack adjuster of the present application may have three kinds of restricting units 23 in the embodiments of the present application, embodiment 3, and embodiment 4.
