Description

Technical Field

[0001] The utility model relates to the technical field of soles, in particular to a high-tensile-performance anti-skid rubber sole. Background Art

[0002] The sole is the bottom layer of the shoe that contacts the road surface and is mostly made of rubber. Normally, the sole is subjected to bending and stretching during wear. After prolonged wear, the sole is prone to forming fragile areas of aging and fatigue at the locations where the sole is frequently bent and stretched. These areas are likely to become damaged or even break. Most rubber soles rely solely on tread patterns for anti-slip protection, and these patterns are easily worn, causing the anti-slip properties of the sole to decrease rapidly. All of the above situations will shorten the service life of the sole. Utility Model Content

[0003] The purpose of the utility model is to provide a high tensile strength and non-slip rubber sole to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a high-tensile-resistance anti-slip rubber sole, comprising an anti-bending layer, an anti-stretching layer and an anti-slip bottom layer arranged in sequence from top to bottom, a cavity is provided inside the anti-bending layer, an airbag is provided in the cavity, a plurality of first grooves and a plurality of second grooves are provided on the upper surface and the lower surface of the anti-stretching layer, the plurality of first grooves are extended longitudinally, and the plurality of second grooves are extended transversely, a first anti-tensile rope extending longitudinally is provided in the first groove, a second anti-tensile rope extending transversely is provided in the second groove, and a plurality of anti-slip slide blocks are provided at the bottom of the anti-slip bottom layer.

[0005] By adopting the above technical solution, when the sole body is bent and stretched during wearing, because the cavity in the anti-bending layer is a sealed structure, the cavity in the air cushion cannot be discharged, which can provide a certain resistance to the bending of the sole, thereby improving the anti-bending performance of the sole. At the same time, the first anti-tension rope and the second anti-tension rope can transfer the tensile force to adjacent parts, so that the anti-tension layer is evenly stressed and deformed, and the deformation difference of each part is reduced, thereby enhancing the anti-bending and anti-stretching performance of the sole body. An anti-slip block is set on the anti-slip bottom layer to increase the anti-slip effect of the sole body. Compared with ordinary patterns, the anti-slip block is raised and has a longer service life.

[0006] As a further optimization of the present invention, there are two cavities, which are respectively located at the forefoot position and the rear foot position of the anti-bending layer.

[0007] By adopting the above technical solution, two cavities are set at the front and back, thereby setting two air cushions, so that the front and back soles of the sole can have a certain anti-bending performance.

[0008] As a further optimization of the present invention, the first groove and the second groove are arranged to communicate with each other, and the second tension ropes are arranged in pairs and are respectively located above and below the first tension rope.

[0009] With the above technical solution, the first tensile rope is longer and more prone to large bending. The second tensile rope limits the upper and lower positions of the first tensile rope, reducing the risk of the first tensile rope breaking after being subjected to large bending.

[0010] As a further optimization of the present invention, a number of reinforcement blocks are provided at intervals along the length direction on both sides of the sole body. The reinforcement blocks are cross-shaped, and the upper ends of the reinforcement blocks are fixed to the anti-bending layer and the lower ends are fixed to the anti-stretching layer.

[0011] By adopting the above technical solution, the reinforcement block is provided, which not only makes the anti-tensile layer and the anti-bending layer more tightly connected, but also further improves the tensile and bending resistance of the sole body, thereby enhancing the structural strength of the sole body.

[0012] As a further optimization of the present invention, the cross-sectional shape of the anti-sliding block is a truncated cone that is narrow at the top and wide at the bottom, and an anti-slip groove is provided at the bottom of the anti-sliding block.

[0013] By adopting the above technical solution, the anti-slip block is set to be narrow at the top and wide at the bottom, thereby increasing the contact area with the ground. The anti-slip groove increases the friction between the anti-slip block and the ground, improving the anti-slip effect.

[0014] As a further optimization of the present invention, the anti-slip groove is wavy in shape.

[0015] By adopting the above technical solution, the provision of the wavy anti-skid groove can have a better anti-skid effect when walking, accelerating or on uneven ground.

[0016] The beneficial effects of the present invention are as follows: when the sole body is bent and stretched during wearing, because the cavity in the anti-bending layer is a sealed structure, the cavity in the air cushion cannot be discharged, which can provide a certain resistance to the bending of the sole, thereby improving the anti-bending performance of the sole. At the same time, the first anti-tension rope and the second anti-tension rope can transmit the tensile force to adjacent parts, so that the anti-tension layer is evenly stressed and deformed, and the deformation difference of each part is reduced, thereby enhancing the anti-bending and anti-stretching performance of the sole body. An anti-slip block is arranged on the anti-slip bottom layer to increase the anti-slip effect of the sole body. Compared with ordinary patterns, the anti-slip block is raised and has a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0023] See attached Figure 1-3 , the embodiment disclosed in the present utility model further provides: a high tensile performance anti-skid rubber sole, comprising an anti-bending layer 11, an anti-stretching layer 12 and an anti-skid bottom layer 13 arranged in sequence from top to bottom;

[0024] The anti-bending layer 11 has two cavities 2 formed therein, one at the forefoot and the other at the rear foot of the anti-bending layer 11 . Air bags are provided in the cavities 2 .

[0025] The upper and lower surfaces of the anti-stretch layer 12 are each provided with a plurality of first grooves 3 and a plurality of second grooves 4. The plurality of first grooves 3 are provided in the longitudinal direction, and the plurality of second grooves 4 are provided in the transverse direction. A first tensile cord 31 extending longitudinally is provided in the first groove 3, and a second tensile cord 41 extending transversely is provided in the second groove 4. The first groove 3 and the second groove 4 are provided in communication with each other. The second tensile cords 41 are provided in pairs and are respectively located above and below the first tensile cord 31.

[0026] Furthermore, a plurality of reinforcing blocks 6 are provided at intervals along the length direction on both sides of the sole body. The reinforcing blocks 6 are cross-shaped. The upper ends of the reinforcing blocks 6 are fixed to the anti-bending layer 11, and the lower ends are fixed to the anti-stretching layer 12.

[0027] The bottom of the anti-slip bottom layer 13 is provided with a plurality of anti-slip blocks 5. The cross-section of the anti-slip blocks 5 is a truncated cone with a narrow upper portion and a wide lower portion. The bottom of the anti-slip blocks 5 is provided with an anti-slip groove 51. The shape of the anti-slip groove 51 is wavy.

[0028] The principle of the present invention is as follows: when the sole body is bent and stretched during wearing, because the cavity 2 in the anti-bending layer 11 is a sealed structure, the cavity 2 in the air cushion 21 cannot be discharged, which can provide a certain resistance to the bending of the sole, thereby improving the anti-bending performance of the sole. At the same time, the first anti-tension rope 31 and the second anti-tension rope 41 can transfer the tensile force to adjacent parts, so that the tensile layer is evenly stressed and deformed, and the deformation difference between different parts is reduced, thereby enhancing the anti-bending and anti-stretching performance of the sole body.

[0029] The reinforcement block 6 not only makes the anti-stretching layer 12 and the anti-bending layer 11 more tightly connected, but also further improves the anti-stretching and anti-bending properties of the sole body, thereby enhancing the structural strength of the sole body.

[0030] An anti-slip block 5 is provided on the anti-slip bottom layer 13 to increase the anti-slip effect of the sole body. Compared with ordinary patterns, the anti-slip block 5 is provided in a raised manner and has a longer service life. The anti-slip block 5 is provided to be narrow at the top and wide at the bottom, thereby increasing the contact area with the ground. The anti-slip groove 51 increases the friction between the anti-slip block 5 and the ground, thereby improving the anti-slip effect. The wavy anti-slip groove 51 can have a better anti-slip effect when walking, accelerating or on uneven ground.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications based on the above assumptions should also be regarded as within the scope of protection of the present invention.
