Description

Technical Field

[0001] This utility model relates to the field of anti-slip shoe sole technology, specifically a retractable anti-slip shoe spike. Background Technology

[0002] The construction of shoe soles is quite complex. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole, and heel. In a narrow sense, it refers only to the outsole. Common characteristics of shoe sole materials should include abrasion resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy adaptation to foot shape, resistance to deformation after shaping, heat retention, and easy absorption of moisture. At the same time, it should work with the midsole to provide braking effect when changing feet to prevent slipping and to facilitate stopping. There are many types of shoe sole materials, which can be divided into natural sole materials and synthetic sole materials. Natural sole materials include natural leather, bamboo, wood, etc., while synthetic sole materials include rubber, plastic, rubber and plastic composite materials, recycled leather, and flexible cardboard.

[0003] In environments where strong grip is required, users typically need to wear spiked shoes to improve traction. As a result, various anti-slip products have been invented. For example, there is an anti-slip shoe sole that uses threaded conical anti-slip studs. However, anti-slip studs are not easy to disassemble and replace, and they are often fixed, affecting the comfort of use. Utility Model Content

[0015] Compared with the prior art, this utility model provides a retractable anti-slip shoe spike, which has the following beneficial effects:

[0016] This type of retractable anti-slip shoe spike is easy to install. Simply press the flange of the fastening block into the pre-made annular groove on the sole to secure it. Disassembly is quick and easy; the spike head protrudes from the sole and fastening block, sliding along the inside of the support base. This causes the telescopic spring to expand and contract, allowing the spike head to extend and retract. This provides a safer and more comfortable walking experience, especially on slippery surfaces like mountains, fishing, and ice, increasing safety and comfort. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: Please refer to Figures 1-2 A retractable anti-slip spike includes an anti-slip spike structure 1, which includes a support base 11, a fastening block 12, a telescopic spring 13, a spike body 14, and a conical anti-slip spike head 15. The support base 11 is fitted with the bottom of the fastening block 12. The fastening block 12 is made of plastic and has a flange structure on its top for embedding into the groove of the sole. The telescopic spring 13 is fixedly installed in the inner cavity of the fastening block 12. The spike body 14 is fixed to the lower end of the telescopic spring 13, and the upper end of the spike body 14 is embedded in the inner cavity of the fastening block 12. The spike body 14 slides within the middle cavity of the support base 11. The spike body 14 can retract into the inner cavity of the fastening block 12 when compressed and return to its original position after the pressure is released by the telescopic spring 13. The spike body 14 is fixed to the upper end of the conical anti-slip spike head 15.

[0033] In some embodiments, the flange structure of the fastening block 12 is an annular buckle with an outer diameter larger than the main body diameter of the fastening block 12. It is used to make an interference fit with the pre-set annular groove 2 of the sole 3, so as to realize the tool-free disassembly and assembly of the sole 3. The conical anti-slip nail head 15 has a cone angle of 30°-45° and the surface of the nail head is provided with anti-slip texture to prevent slipping while walking and enhance grip. The inner cavity of the fastening block 12 is provided with a wear-resistant bushing made of polytetrafluoroethylene or ceramic.

[0034] In this application, the fastening block 12 is injection molded from nylon 66, and the outer diameter of the flange structure can be 12mm and the thickness can be 2mm; the telescopic spring 13 is made of 304 stainless steel with a wire diameter of 0.8mm and a free height of 15mm; the conical anti-slip nail head 15 of the nail body 14 has a cone angle of 40°.

[0035] During installation, the flange structure of the fastening block 12 is pressed into the pre-made annular groove 2 of the sole 3 to complete the fixation. During disassembly, the flange can be pried off with a tool.

[0036] When in use, the anti-slip spike head 15 protrudes from the sole 3 and the buckle block 12, and slides on the inside of the support seat 11 through the spike body 14, so that the telescopic spring 13 is compressed and extended, allowing the anti-slip spike head 15 to extend and retract, making it convenient for users to walk on slippery roads and ice surfaces, playing an anti-slip role and increasing the safety and comfort of walking.

[0037] Example 2: Please refer to Figure 3 A retractable anti-slip shoe spike, wherein the anti-slip shoe spike structure 1 is provided in two sets, and the anti-slip shoe spike structure 1 is fixed by connecting block 4 and connected together to form a synchronous anti-slip function.

[0038] In this application, the connecting block 4 is made of the same material as the fastening block 12, and the connecting block 4 is fixed to the support base 11 of the two sets of anti-slip shoe nail structures 1 and is flush with the lower end of the support base 11, so that the sole 3 is provided with two sets of protruding conical anti-slip nail heads 15, which is more conducive to anti-slip. Of course, the anti-slip shoe nail structure 1 can also be provided with three or four sets, depending on the actual situation, and is not limited here.

[0039] Example 3: Please refer to Figure 4 A retractable anti-slip shoe nail, wherein the surface of the conical anti-slip nail head 15 is provided with vertically distributed arc-shaped inner grooves, which increase the friction with the ground and thus play an anti-slip role.

[0040] Example 4: Please refer to Figure 5 A retractable anti-slip shoe nail, wherein the surface of the conical anti-slip nail head 15 is vertically distributed with anti-slip protrusions, which increase the friction with the ground and thus play an anti-slip role.
