Abstract

The present invention relates to a rotatable anti-slip device and an all-terrain anti-slip shoe sole. By installing a rotating part, the anti-slip mechanism can be inverted relative to the mounting base. Specifically, by installing a sphere, the rotation axis can rotate along the spherical surface. Simultaneously, by installing the rotation axis between the sphere and the friction part, the rotation direction of the rotation axis can be restricted, allowing the friction part to invert along the rotation axis. The friction part has a first friction surface and a second friction surface. By flipping and adjusting the friction part according to the terrain, the user can adapt to the anti-slip needs of various terrains, thereby effectively improving the anti-slip effect on various terrains. Furthermore, since the anti-slip device can be easily replaced, the loss of the shoe's anti-slip function due to unexpected accidents or damage is prevented.

Description

Rotatable Anti-Slip Device and All-Terrain Anti-Slip Shoe Sole The present invention belongs to the field of shoe manufacturing technology and, in particular, relates to a rotatable anti-slip device and an all-terrain anti-slip shoe sole. The sole is an important component of a shoe and possesses characteristics such as wear resistance and pressure resistance, among which the anti-slip function is one of the main functions of the sole. In conventional technology, slipping was generally prevented on hard surfaces by increasing friction through the pattern of the sole. However, slipping is difficult to prevent with the sole pattern alone when the road surface freezes due to rain or snow, or during outdoor activities (hiking, fishing). In such cases, slipping is generally prevented by driving spikes into the ground, but walking on hard surfaces while wearing spiked shoes can cause discomfort to the feet and easily lead to damage to the spikes. In conventional sports such as hiking, one must cope with complex terrain and carry two pairs of shoes with different sole structures, which is inconvenient. Among the prior art, publication numbers US7269916B2 (2005.04.19), EP1558103A1 (2005.08.03), and CN117617628A (2022.08.11) are all sole patents including anti-slip devices. However, the anti-slip device and sole among these are fixed in a dual-axis connection position, and assembly is inconvenient. Therefore, it is very necessary to design a rotatable anti-slip device and an anti-slip shoe sole.

The friction part (121) has a first friction surface (125) and a second friction surface (126). The user can adapt to the anti-slip needs in various terrains by flipping and adjusting the friction part (121) according to the terrain, thereby effectively improving the anti-slip effect in various terrains. The above anti-slip part (127) includes a spike or a spike patch, and in the anti-slip mechanism (12), the friction part (121) and the rotating part (122) are made of TPU material, and the anti-slip part (127) is made of tungsten steel material, and the friction part (121), the rotating part (122), and the anti-slip part (127) are integrally molded through mold processing, and in the actual implementation process, the anti-slip part (127) strengthens the gripping force of the second friction surface (
