Description

Technical Field

[0001] The utility model relates to the technical field of shoemaking, in particular to an anti-skid device and an all-terrain anti-skid sole which are convenient to assemble and disassemble. Background Art

[0002] As an important part of shoes, the sole has the characteristics of wear resistance and pressure resistance, among which anti-skid function is one of the main functions of the sole. In the prior art, the sole pattern is generally used to increase friction on hard roads to achieve the purpose of anti-skid; but when encountering rainy and snowy weather that causes icy roads or outdoor sports (mountain climbing, fishing), it is difficult to prevent slipping only by the sole pattern. The usual practice is to insert spikes into the ground to prevent slipping. However, when wearing spiked shoes on hard roads, it makes the feet feel uncomfortable and easily causes the spikes to be damaged.

[0003] In existing sports such as mountaineering, it is necessary to deal with complex road surfaces, and carrying two pairs of shoes with different soles will also bring great inconvenience. In the prior art, publication numbers US7269916B2 (2005.04.19), EP1558103A1 (2005.08.03), and CN117617628A (2022.08.11) are all patents for soles with anti-skid devices. The connection between the anti-skid device and the sole is a biaxial connection positioning, which is inconvenient to assemble. Therefore, it is very necessary to design an anti-skid device and an anti-skid sole to solve the above problems. Utility Model Content

[0078] The mounting groove 21 includes a seat groove section 211 matched with the mounting seat 11, a limiting retaining wall 212 surrounding the outer side of the seat groove section 211, and a clamping hole 213 arranged at the bottom of the seat groove section 211; the clamping hole 213 is used to fix the clamping cone head 115. In the actual implementation process, the mounting seat 11 is conveniently installed through the cooperation of the clamping hole 213 and the clamping cone head 115, so that the connection of the mounting seat 11 is more firm and reliable.

[0079] The installation groove 21 also includes an anti-skid groove section 214 that cooperates with the anti-skid mechanism 12; the anti-skid groove section 214 includes a friction groove section 215 that cooperates with the friction strip 129.

The side wall 216 is higher than the friction strip 129, and the height difference between the side wall 216 and the friction strip 129 is 2-3.5 mm.

In the actual implementation process, when the friction strip 129 is installed in the friction groove section 215, the friction strip 129 can be effectively fixed, making the installation of the friction strip 129 more firm and reliable. At the same time, when the friction groove section 215 is deformed by force, the thick convex section 1293 and the thin concave section 1294 form a wavy surface, which can effectively increase the friction area and prevent the friction strip 129 from slipping out of the friction groove section 215.

[0082] The friction groove section further includes an insertion hole 218 disposed on the groove bottom surface 217; the insertion hole 218 cooperates with the anti-slip accessory 127.

In actual implementation, the ejection point 1296 is set on the same plane as the ground of the anti-skid sole. When the sole contacts the ground, the ejection point 1296 contacts the ground before the second end 1292, effectively preventing the second end 1292 from unintentionally escaping from the friction groove section 215, thereby making the anti-skid device firmly and reliably fixed on the anti-skid sole during walking.

[0087] The mounting slot 21 further includes a clearance slot 2101; the friction slot section 215 is connected between the clearance slot 2101 and the rotation slot section 2141. In actual implementation, the clearance slot 2101 can accommodate a finger to facilitate the second end 1292 to escape and switch the first friction surface 125 or the second friction surface 126.
