The bottom plate 111 is provided with a plurality of protruding holes 111a, and the diameter of the protruding holes 111a is slightly larger than the diameter of the spike 123, so that the spike 123 can protrude out. The number and positions of the protruding holes 111a correspond to those of the spikes 123, so that each spike 123 can protrude from or retract into the mounting box 110 through its corresponding protruding hole 111 a. The length of the shoe spike 123 extending out of the extending hole 111a and the retracted length can be selected and designed according to practical needs, and is not particularly limited herein. The plurality of spikes 123 and the spike plate 122 may be integrally formed or may be separately formed. The plurality of spikes 123 may be fixedly attached to the spike plate 122 by welding or the like. It will be appreciated that each spike 123 has a pointed end for gripping the ground to enhance the slip resistance of the shoe. The tips of the plurality of spikes 123 each extend away from the cover plate 112 to extend or retract from the extension holes 111a on the base plate 111. The number of the studs 123 may be 4, 6, 8, 10, 12, etc., and may be specifically selected and designed according to actual use requirements, which is not specifically limited herein. Optionally, a plurality of cleats 123 are evenly spaced across the width and length of cleat plate 122. In order to enhance the structural strength of the spike assembly 120, the spike 123 and the spike plate 122 are made of metal, for example, the spike 123 and the spike plate 122 are made of stainless steel. Optionally, the nail plate 122 is provided with a reinforcing guard towards the wall of the bottom plate 111, the reinforcing guard surrounding and connecting the plurality of nails 123. So, strengthen the backplate and play the connection reinforcing effect to a plurality of spikes 123, promote the joint strength between a plurality of spikes 123 and the nail board 122, and then guarantee spike subassembly 120's overall structure intensity, avoid spike 123 fracture and spike 123 and nail board 122 to break away from. The reinforcing guard plate can be made of metal materials such as stainless steel and the like, and the reinforcing guard plate and the nail plate 122 are integrally formed.

The spike plate 122 is disposed between the cover plate 112 and the base plate 111, and can move up and down between the cover plate 112 and the base plate 111 to drive the plurality of spikes 123 to extend or retract into the extending holes 111 a. The elastic restoring member 121 may specifically include one or more springs, and the elastic restoring member 121 also includes a damper, which only needs to elastically connect the nail plate 122 and the mounting box 110, so that the nail plate 122 can be restored to a position close to the cover plate 112 under the action of the elastic restoring member 121. Optionally, the elastic restoring member 121 extends in the up-down direction. It will be appreciated that the plurality of studs 123 are disposed to extend out of the outlet aperture 111a and the sole 200 when the locking lever 130 is in the locked position. When the locking handle 130 is switched to the unlocking position, the locking surface 40a of the thrust block 131a faces the nail plate 122, that is, the entire thrust block 131a rotates to be away from the nail plate 122 toward the side away from the stop bar 112a, specifically, the side wall surface of the thrust block 131a can be attached to the inner wall surface of the cover plate 112, so that the nail plate 122 returns to the position close to the cover plate 112 under the action of the elastic restoring member 121, and the length of the spike 123 extending out of the extending hole 111a is reduced. When the locking handle 130 is in the unlocked position, specifically, the spike 123 may be retracted into the extending hole 111a, or the spike 123 may be retracted to a position extending out of the extending hole 111a, or retracted to a position away from the extending hole 111a, only by reducing the extending length of the spike 123 compared to the locking position.

The cover plate 112 is provided with a stopper 112a protruding toward the inner wall surface of the bottom plate 111, and the stopper 112a extends in a lateral direction, that is, a horizontal direction. The length of the stop bar 112a protruding from the cover plate 112 may be designed according to the size of the locking handle 130. The stop bar 112a has a limiting surface 10a extending from top to bottom and inclined transversely, and an area of the inner wall surface of the cover plate 112 close to the limiting surface 10a is arranged at an obtuse angle with the limiting surface 10a, that is, arranged toward the bottom plate 111 along the limiting surface 10a extending from top to bottom. In general, in order to provide a sufficient contact area between the stopper surface 10a and the lock surface 40a, the area of the stopper surface 10a is ensured so that the stopper surface 10a is a plate surface with a long stopper bar.

The locking handle 130 is disposed in an elongated shape and extends along the length of the stop bar 112 a. In order to improve the structural strength, the locking handle 130 may be made of a metal material, such as stainless steel, or may be made of hardware. The thrust block 131a is disposed at one side of the rotation shaft 131, and in order to improve the structural strength of the locking handle 130, the thrust block 131a may be optionally integrally formed with the rotation shaft 131. Of course, the thrust block 131a may be formed separately from the rotary shaft 131. One end of the rotating shaft 131 provided with the thrust block 131a protrudes into the mounting case 110 such that the thrust block 131a is located between the cover plate 112 and the nail plate 122, and the other end of the rotating shaft 131 protrudes out of the mounting case 110 to form the operation section 132. The operation section 132 may further extend out of the sidewall surface of the sole 200 for the user to manipulate, and the user may operate the operation section 132 on the outer side of the shoe to switch the locking position and the unlocking position of the locking handle 130.

The thrust block 131a is located at one side of the stop bar 112a, and the thrust block 131a has a locking surface 40a facing the stop bar 112a, so that the locking surface 40a is embodied as a locking plane to be in limit abutment with the limit surface 10a, and the thrust block 131a is prevented from continuing to rotate towards the side where the stop bar 112a is located. And the thrust block 131a has a convex arc surface 30a away from the rotation shaft 131, that is, the free end of the thrust block 131a is arranged in an arc shape. In this way, the thrust block 131a and the nail plate 122 are in line contact or surface contact close to line contact, so that the friction area between the thrust block 131a and the nail plate 122 can be greatly reduced, and the user can switch the unlocking position and the locking position through the locking handle 130 more easily. It is understood that the convex arc surface 30a has a low point region a2, a first high point region a1 and a second high point region a3 located at both sides of the low point region a2, the distance from the low point region a2 to the axis of the rotation shaft 131 is R1, the distances from the first high point region a1 and the second high point region a3 to the axis of the rotation shaft 131 are R2 and R3, respectively, wherein both R2 and R3 are smaller than R1. That is, in the cross section of the thrust block 131a, the low point region a2 is the lowest region of the thrust block 131a, and the first high point region a1 and the second high point region a3 are regions higher on both sides of the lowest region. It should be noted that when the low point region a2 of the thrust block 131a abuts against the nail plate 122, the thrust block 131a is located at the "dead point" position, which can prevent the nail plate 122 from moving upward when being stressed, so that the locking handle 130 locks the nail plate 122. Since the anti-slip device 100 is installed on the sole 200, when the user walks with the shoe, the user inevitably shakes forward, backward, leftward and rightward, and the nail plate 122 also shakes forward, backward, leftward and rightward, so that the user can easily make the thrust block 131a cross the dead point when walking, and then the thrust block 131a can be separated from the nail plate 122, so that the nail plate 122 drives the shoe nail 123 to retract into the extending hole 111a under the action of the elastic restoring piece 121. Thus, the situation that the shoe nails 123 retract back may occur in the walking process of the user, and the situation is uncontrollable, so that the product quality problem is easily caused, and the use experience of the user is affected.

This embodiment is implemented by making the locking surface 40a abut against the stopper surface 10a, the first high point region a1 abut against the nail plate 122, and the second high point region a3 and the low point region a2 disengage from the nail plate 122 when the locking handle 130 is switched to the locking position, i.e. the locking handle 130 actively crosses the "dead point" position when in the locking position, so that the entire thrust block 131a is disposed obliquely toward the stopper bar 112 a. So, can carry out effectual locking to nail board 122, when the locking position, when nail board 122 is inevitable when rocking about, can not make thrust block 131a rotate and break away from nail board 122 towards the direction of keeping away from backstop strip 112a, and spike 123 is in the position of stretching out hole 111a all the time, and then avoids the user to appear the condition that spike 123 retracted in the in-process of walking, improves product quality, promotes customer and uses experience.

The user switches the locking position and the unlocking position of the locking handle 130 by operating the operation section 132 in which the rotating shaft 131 protrudes from the mounting case 110. When the locking handle 130 is switched from the unlocking position to the locking position, the rotating shaft 131 rotates to drive the thrust block 131a to rotate towards the stop bar 112a, so that the low point region a2 of the convex arc surface 30a of the thrust block 131a passes over the nail plate 122, finally the first high point region a1 abuts against the nail plate 122, the locking surface 40a abuts against the limiting surface 10a, and the limiting thrust block 131a rotates, so that the thrust block 131a pushes the nail plate 122 to move downwards to drive the spikes 123 to extend out of the extending holes 111a and the sole 200, and the anti-skid shoe can walk on ice or mountains. When the locking handle 130 is switched from the locking position to the unlocking position, the rotating shaft 131 rotates to drive the thrust block 131a to be away from the stop strip 112a and rotate to the horizontal position, so that the convex arc surface 30a of the thrust block 131a is away from the nail plate 122, and finally the locking surface 40a of the thrust block 131a faces the nail plate 122, at the moment, the nail plate 122 moves towards the cover plate 112 under the action of the elastic restoring piece 121, and then the length of the plurality of shoe studs 123 extending out of the extending holes 111a is reduced, and then the plurality of shoe studs 123 retract into the shoe sole 200, so that the anti-skid shoe can walk as a normal shoe, the ground is prevented from being scratched, and the walking difficulty is reduced.

According to the utility model, by arranging the mounting box 110, the structures such as the shoe spike component 120, the elastic restoring piece 121, the locking handle 130 and the like are integrated on the mounting box 110, so that the whole sole antiskid device 100 is modularized, the batch production of the sole antiskid device 100 is more convenient, and the mounting efficiency of the sole antiskid device 100 in the sole 200 is improved. And can switch spike 123 through locking handle 130 and stretch out sole 200 or retract into sole 200, then when spike 123 stretches out sole 200, make shoes can walk on the special condition such as ice surface or mountain, effectively avoid slipping, and when spike 123 retracts into sole 200, make anti-skidding shoes can regard as normal shoes walking, avoid scraping colored ground, reduce the walking degree of difficulty, thereby satisfy the user to the different user demands of shoes under different scenes.

The cover plate 112 of the mounting box 110 is provided with a stop strip 112a protruding towards the inner wall surface of the bottom plate 111, the stop strip 112a has a limiting surface 10a extending from top to bottom and inclining transversely, and an area of the inner wall surface of the cover plate 112 close to the limiting surface 10a forms an obtuse angle with the limiting surface 10 a. The stop bar 112a is configured to limit the locking handle 130 and prevent the thrust block 131a from continuing to rotate toward the side where the stop bar 112a is located. The convex arc surface 30a of the thrust block 131a makes the thrust block 131a and the nail plate 122 in line contact or surface contact close to line contact, so that the friction area between the thrust block 131a and the nail plate 122 can be greatly reduced, and the user can switch the unlocking position and the locking position through the locking handle 130 more easily. When the locking handle 130 is at the locking position, under the resilience action of the elastic restoring piece 121, the first high point area a1 of the thrust block 131a abuts against the nail plate 122, the second high point area a3 and the low point area a2 are separated from the nail plate 122, so that the thrust block 131a crosses the "dead point" position, and then the nail plate 122 can be effectively locked, when the nail plate 122 inevitably shakes left and right at the locking position, the resilience of the elastic restoring piece 121 enables the nail plate 122 to always abut against the thrust block 131a, the thrust block 131a cannot rotate in the direction away from the stopper bar 112a to separate from the nail plate 122, and the shoe nail 123 is always in the position extending out of the extending hole 111a, thereby avoiding the situation that the shoe nail 123 retracts during the walking process of the user, improving the product quality, improving the use experience of the user, and having a simple and ingenious overall structure, facilitating the switching between the unlocking position and the locking position while preventing the shoe nail 123 from retracting during the walking process, low processing cost, easy molding and manufacture and suitability for mass production.
