[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] The present application embodiment discloses a puncture-proof sole. Figure 1 and Figure 2 A puncture-proof sole comprises a sole body 1 and a plurality of supporting protrusions 2, wherein the plurality of supporting protrusions 2 are connected to the lower surface of the sole body 1, and a plurality of avoidance grooves 3 are defined between adjacent supporting protrusions 2, and the hardness of the supporting protrusions 2 is greater than the hardness of the sole body 1. The sole body 1 is provided with a metal sheet 4 at the bottom of the avoidance groove 3. Thus, by providing the supporting protrusions 2 on the sole body 1, the thickness of the sole is thickened at the position where the supporting protrusions 2 are provided, and it is not easy to be punctured; and the supporting protrusions 2 raise the entire sole body 1, so that at the position of the avoidance groove 3, the avoidance groove 3 plays a role in accommodating sharp objects; and the metal sheet 4 is provided at the bottom of the avoidance groove 3, thereby reducing the risk of the sole being punctured, and at the same time making the shoes made of the sole relatively light.
[0032] Specifically, the side wall of the support protrusion 2 is inclined, and the width of the avoidance groove 3 gradually increases from one side close to the sole body 1 to the other side. When the sole steps on a sharp object, the side wall of the inclined support protrusion 2 is used to guide the sharp object to move, so that the bottom of the sharp object box avoidance groove 3 moves, thereby further reducing the risk of sharp objects piercing the sole.
[0033] The bottom of the avoidance groove 3 is arranged in an arc shape, and the depth of the avoidance groove 3 increases first and then decreases from one side to the other side, so as to further enhance the guiding effect of the groove wall of the avoidance groove 3 on sharp objects.
[0034] Reference Figure 3 , wherein the specific connection method of the metal sheet 4 and the sole body 1 is as follows: the metal sheet 4 is penetrated with a plurality of groups of through holes 41, and each group of through holes 41 includes two through holes 41. A metal wire ring 5 is penetrated in each group of through holes 41, and the metal wire ring 5 includes a contact portion 51 and an embedding portion 52, wherein the contact portion 51 contacts the surface of the metal sheet 4 away from the sole, and the embedding portion 52 is embedded in the sole. When the metal sheet 4 is connected to the sole body 1, the two ends of the metal wire ring 5 are respectively passed through the two through holes 41 of a group, so that the contact portion 51 located in the middle of the metal wire ring 5 contacts the surface of the metal sheet 4 away from the sole body 1, and then the support strip protrusion and the sole body 1 are molded, so that the embedding portion 52 of the metal wire ring 5 is embedded in the sole body 1, thereby establishing a stable connection between the metal sheet 4 and the sole body 1.
[0035] In order to further improve the connection strength between the metal sheet 4 and the sole body 1 , metal connecting wires 53 may be provided between the metal wire rings 5 , and the adjacent embedded portions 52 may be connected by the connecting wires 53 .
[0036] Furthermore, an elastic pad 42 is provided on the surface of the metal sheet 4 facing away from the sole body 1, and the elastic pad 42 is used to isolate sharp objects from the metal sheet 4, reduce the noise generated by the friction between the sharp objects and the metal sheet 4, and improve the wearing comfort of the shoes made of the sole.
[0037] In this embodiment, the elastic pad 42 is detachably connected to the metal sheet 4, so that the elastic pad 42 can be replaced after the elastic pad 42 is severely damaged.
[0038] Reference Figure 4 In this embodiment, the specific structure of the detachable connection between the elastic pad 42 and the metal sheet 4 is as follows: the metal sheet 4 is bonded with a Velcro hook surface 43, and the surface of the elastic pad 42 facing the metal sheet 4 is bonded with a Velcro fleece surface 44, and the detachable connection between the elastic pad 42 and the metal sheet 4 is achieved by the cooperation between the Velcro hook surface 43 and the Velcro fleece surface 44. In other embodiments, the elastic pad 42 and the metal sheet 4 can also be connected to each other by double-sided tape.
[0039] The implementation principle of the puncture-proof sole in the embodiment of the present application is as follows: when a wearer walks in the shoes made of the sole, the sole is not easily pierced by sharp objects because the thickness of the sole is thicker at the position where the support protrusions 2 are provided, and at the position where the avoidance grooves 3 are formed between adjacent support protrusions 2, the avoidance grooves 3 serve to accommodate sharp objects, and the metal sheets 4 thereof form an obstacle to sharp objects, thereby reducing the risk of sharp objects piercing the sole, while ensuring the lightness of the sole.
[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
