Description

Technical Field

[0001] This utility model relates to the field of shoe sole structure technology, specifically to a PU shoe sole with good anti-slip effect. Background Technology

[0002] PU soles are a lightweight, durable, elastic, and aesthetically pleasing material suitable for various types of shoes, offering a comfortable wearing experience and making them popular with consumers. However, PU soles also have drawbacks such as poor slip resistance and susceptibility to hydrolysis. Therefore, a PU sole with superior slip resistance has been developed. Utility Model Content

[0003] The purpose of this invention is to provide a PU shoe sole with good anti-slip effect, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a PU shoe sole with good anti-slip effect, comprising a shoe sole body, a first anti-slip pad and a second anti-slip pad, wherein the shoe sole body is provided with a thickened part at the rear foot position, and the first anti-slip pad, the second anti-slip pad and the thickened part are arranged sequentially from front to back at the bottom of the shoe sole body;

[0005] The first anti-slip mat is provided with multiple strip grooves, each strip groove is V-shaped and the opening of the V-shaped strip groove faces backward, and the multiple strip grooves are arranged sequentially from front to back;

[0006] The second anti-slip pad has multiple rectangular countersunk holes arranged in an array;

[0007] The thickened part is integrally formed with the main body of the sole. The thickened part has a diamond-shaped groove and an elliptical protrusion in the center of the groove. The bottom surface of the protrusion is flush with the bottom surface of the thickened part.

[0008] Preferably, each of the strip grooves has a slope that gradually slopes from front to back towards the main body of the sole at the edge near the front side.

[0009] Preferably, the first anti-slip pad is made of rubber.

[0010] Preferably, the edges of the rectangular countersunk hole are all chamfered, and the opening of the rectangular countersunk hole gradually increases from the inside to the outside.

[0011] Preferably, the second anti-slip mat has a rubber sole.

[0012] Preferably, the main body of the sole and the thickened part are made of PU material.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting a first anti-slip pad, when the user walks forward normally, a backward force is generated on the forefoot. Through multiple V-shaped grooves with the openings of the V-shaped grooves facing backward, this structure can increase the contact area between the road surface and the main body of the shoe sole, improve friction, and enhance the anti-slip effect when walking.

[0015] 2. By adding a thickened section, this utility model ensures that when a user stands, most of their weight is concentrated on the heel. This thickening not only guarantees user comfort but also prevents excessive wear and tear that could render the sole unusable. Furthermore, the grooves and protrusions on the thickened section form a suction cup structure, creating negative pressure between the sole and the smooth ground when the user stands, further enhancing stability. When the user walks, the entire sole bends and deforms, easily and quickly detaching from the negative pressure on the ground without affecting normal walking. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1 to 3 The present invention provides an embodiment of a PU shoe sole with good anti-slip effect, comprising an integrally molded shoe sole body 1 and a thickened part 4, as well as a first anti-slip pad 2 and a second anti-slip pad 3 disposed at the bottom of the shoe sole body 1. The thickened part is located below the heel position of the shoe sole body 1, and the first anti-slip pad 2, the second anti-slip pad 3 and the thickened part 4 are disposed sequentially from front to back at the bottom of the shoe sole body 1.

[0023] The first anti-slip pad 2 and the second anti-slip pad 3 are set in sections. When the user walks, the main bending position of the sole body 1 is between the first anti-slip pad 2 and the second anti-slip pad 3. The section setting can reduce the bending deformation of the first anti-slip pad 2 and the second anti-slip pad 3, reduce wear, and further improve the service life of the sole body 1.

[0024] The first anti-slip pad 2 is made of rubber. A rubber sole refers to a shoe sole made of rubber, which can be broadly categorized into natural rubber and synthetic rubber. Natural rubber is advantageous because it is very soft and has excellent elasticity, making it suitable for various sports and providing shock absorption. This increases the wear resistance and anti-slip properties of the sole structure. The first anti-slip pad 2 has multiple grooves 5, each groove 5 being V-shaped with its opening facing backward. These grooves 5 are arranged sequentially from front to back. This structure increases the contact area between the road surface and the main body of the sole, enhancing friction and improving the anti-slip effect during walking.

[0025] Furthermore, each groove 5 has a slope 9 near its front edge that gradually slopes towards the sole body 1 from front to back. This structure increases the contact area between the sole body 1 and the ground when the user walks, thereby increasing friction and improving the anti-slip effect.

[0026] The second anti-slip pad 3 is a tendon sole. Tendon soles can be made of rubber or plastic, but thermoplastic rubber (TPR) is the most convenient. It is named for its resemblance in color and texture to beef tendon. This material enhances the anti-slip and support properties of the main sole 1, further improving user comfort.

[0027] Furthermore, the second anti-slip pad 3 is provided with an array of rectangular countersunk holes 6, the edges of which are all beveled. The openings of the rectangular countersunk holes 6 gradually increase from the inside to the outside. This structure can increase the contact area between the sole body 1 and the ground, improve friction, and enhance the anti-slip effect.

[0028] The thickened part 4 is integrally formed with the main body of the sole 1. The thickened part 4 has a diamond-shaped groove 7, and an elliptical protrusion 8 is provided in the center of the groove 7. The bottom surface of the protrusion 8 is flush with the bottom surface of the thickened part 4. By thickening, user comfort is ensured while preventing the main body of the sole 1 from becoming unusable due to excessive wear. At the same time, the groove 7 and the protrusion 8 on the thickened part 4 form a suction cup structure. When the user stands, the main body of the sole 1 generates negative pressure adsorption with the smooth ground, which further improves the stability of the user when standing. When the user walks, the entire main body of the sole 1 will bend and deform accordingly, which can easily and quickly detach from the ground and the negative pressure state of the main body of the sole, without affecting the user's normal walking.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
