[0028] Referring to Figure 1 And Figure 2 As shown in an adjustable antiskid force outdoor shoes, including sole 1, and fixed on the top of the shoe 2, the bottom of the shoe 1 injection molding is formed with anti-skid boss 3, in the inside of the shoe 1 embedded with adjustable antiskid device 4, the local outer convex of the adjustable antiskid device 4 to the outside of the shoe 1.

[0029] In the above technical scheme, by adjusting the adjustable antiskid device 4, the grip of the shoe sole 1 can be adjusted, mainly applicable to the use in the stone beach, ice surface and other relatively slippery areas.

[0030] Referring to Figure 3 As shown, the adjustable antiskid device 4 includes box body structure 41, and the slider 42 is slidably arranged in the box body structure 41, and the driving rod 43 is rotationally matched with the box body structure 41, the rotation of the driving rod 43 drives the slider 42 to slide transversely, the box body structure 41 is matched with adjustable antiskid nail structure 44, the sliding of the slider 42 drives the adjustable antiskid nail structure 44 to move out, the box body structure 41 is embedded in the shoe sole 1.

[0031] In the above technical scheme, a plurality of adjustable antiskid nail structures 44 are matched, the displacement of a single slider 42 realizes the outward movement of a plurality of adjustable antiskid nail structures 44, and then increases the grip with the ground.

[0032] Referring to Figure 3 As shown, the bottom of the shoe sole 1 is injection molded with a convex column 121, and the adjustable antiskid nail structure 44 slides out from the position of the convex column 121.

[0033] In the state of the adjustable antiskid nail structure 44 retraction, the convex column 121 itself has antiskid property.

[0034] Referring to Figures 3 to 6As shown, the box structure 41 comprises a box body 411 and a box cover 412, the left side of the box body 411 is provided with an opening, the box cover 412 is fixed at the opening, a sliding groove 413 is processed at the front and rear inner walls of the box body 411, the sliding groove 413 penetrates the opening, the sliding groove 413 is closed by the box cover 412, a bearing 414 is embedded in the right side of the box body 411, the driving rod 43 cooperates with the bearing 414, one end of the driving rod 43 is located in the box body 411, an external threaded part is processed at this end, the other end of the driving rod 43 is processed with a hand screw end 431, the hand screw end 431 is located outside the sole 1; sliding strips 421 matched with the sliding groove 413 are processed at the front and rear sides of the sliding block 42, an internal threaded hole 422 matched with the external threaded part is processed at the right end of the sliding block 42, a driving inclined surface 423 is processed at the bottom of the sliding block 42, the adjustable anti-skid structure 44 is matched with the driving inclined surface 423; a stepped hole 415 is processed at the bottom of the box body 411, the stepped hole 415 corresponds to the protruding column 121, the adjustable anti-skid structure 44 is matched with the stepped hole 415.

[0035] In the above technical scheme, the combination structure of the detachable box body 411 and the box cover 412 is convenient for assembly.

[0036] The box body 411, the box cover 412 and the sliding block 42 are made of super-light aluminum, the overall weight is controllable, and the hardness is sufficient.

[0037] The sliding block 42 slides under the rotating action of the driving rod 43, the adjustable anti-skid structure 44 is driven to move downward by the driving inclined surface 423, and then the grip with the ground is increased.

[0038] As shown in the drawings, Figure 3 As shown, the sole 1 is a double-layer structure, the lower layer is a wear-resistant rubber layer 11, and the upper layer is an EVA layer 12, the driving rod 43 penetrates the EVA layer 12, and the EVA layer 12 elastically wraps the driving rod 43, the protruding column 121 and the wear-resistant rubber layer 11 are integrally formed by injection molding.

[0039] In the above technical scheme, the wear-resistant rubber layer 11 bears the contact with the ground, and the wear resistance is sufficient.

[0040] The EVA material has strong elasticity and high comfort, and as the contact with the sole, the wearing is more comfortable.

[0041] The elasticity of the EVA material contacts the driving rod 43 to complete the wrapping of the driving rod 43, greatly increases the waterproofness, reduces the probability of water entering the box body 411, and increases the rotating damping of the driving rod 43 to reduce the rotation of the driving rod 43 under non-human torsion.

[0042] As shown in the drawings,Figure 3 、 Figure 4 and Figure 7 As shown in FIG. 44, the adjustable stud structure 44 comprises an adjusting screw 441, a spring 442 and a stud 443, the stud 443 is in sliding fit with the convex column 121, the lower end of the stud 443 is a spike part 444, the upper end of the stud 443 is provided with a threaded hole, the adjusting screw 441 is matched with the threaded hole, the upper end of the adjusting screw 441 is a spherical cap 445, the adjusting screw 441 is assembled from the inside of the box body 411 and is screwed into the adjusting screw 441 after passing through the stepped hole downward, the adjusting screw 441 has a light rod part 446 which slides along the stepped hole, the spring 442 is sleeved on the adjusting screw 441 and acts between the spherical cap 445 and the box body 411, the driving slope 423 acts on the spherical cap 445, when the slider 42 slides to the left, the driving slope 423 drives the spherical cap 445 to move downward, at this time, the extension of the stud 443 to the outside of the convex column increases.

[0043] As shown in FIG. 43, the right end of the driving slope 423 is a flat part 433, when the slider 42 slides to the left along the sliding groove to the limit position, the spherical cap 445 is located at the position of the flat part 433, avoiding the spherical cap 445 from sliding out of the driving slope 423. Figure 6

[0044] In the above technical solution, through the rebound of the spring 442, when the slider 42 slides to the right, the stud 443 is automatically retracted upward into the convex column 121, even if the resistance between the convex column 121 and the stud 443 is generated, after the foot sole is stepped on, the stud 443 can also be retracted due to the upper end of the spherical cap 445 losing the pressing.

[0045] When it is needed to increase the grip with the ground, the slider 42 is driven to displace to the left through the rotation of the driving rod 43, and then the spherical cap 445 drives the stud 443 to displace downward under the action of the driving slope 423, so that the spike part 444 moves to the outside of the convex column 121, increasing the grip with the ground.

[0046] It should be noted that the stud 444 can be individually adjusted along the adjusting screw 441, that is, the extension length of each stud 444 can also be individually adjusted, and each stud 444 can also be individually disassembled from the outside, so as to facilitate the maintenance and replacement.

[0047] As shown in FIG. 44, in order to increase the sealing, the device additionally glues and fixes a sealing ring 4444 on the top of the stud 444, and the sealing ring 4444 forms a seal with the inner wall of the convex column 121. Figure 4 ​​
