Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, specifically to a wear-resistant and lightweight rubber foam shoe sole. Background Technology

[0002] The sole is the bottom layer of the shoe that comes into contact with the ground, so it needs to play a good role in slip resistance and wear resistance. Most existing soles are made of rubber foam, which has advantages such as excellent elasticity, good tear resistance, and aging resistance. However, with the improvement of living standards, consumers have also put forward higher requirements for the performance of shoes. They need soles to be not only lightweight, but also more wear-resistant. In particular, when the anti-slip effect of the sole is insufficient, the sole will tilt to the outside when walking. When tilting, the front, back and outside of the sole are prone to contact and scratching with steps, railings, etc., which can easily lead to unsightly damage to the sole and reduce its service life. Utility Model Content

[0003] The purpose of this invention is to provide a wear-resistant and lightweight rubber foam shoe sole to solve the problems mentioned in the background art.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: a wear-resistant lightweight rubber foam shoe sole, including a shoe sole body, the shoe sole body including a mid-bottom layer and a bottom layer, the front end, rear end and outer side of the mid-bottom layer are provided with anti-abrasion plates, the front end, rear end and outer side of the upper surface of the mid-bottom layer are provided with a plurality of grooves spaced along the edge, the bottom layer includes a front bottom, a mid-bottom and a rear bottom, the front bottom is provided with a front anti-slip plate and a plurality of horizontally arranged first anti-slip strips, the plurality of first anti-slip strips are arranged close to the outer side and extend along the longitudinal direction, the rear bottom is provided with a central groove, a rear anti-slip plate and a plurality of horizontally arranged second anti-slip strips, the plurality of second anti-slip strips are arranged close to the outer side and extend along the longitudinal direction.

[0005] By adopting the above technical solutions, front and rear anti-slip plates are set to enhance the wear resistance of the front and rear sides of the outsole. The first and second anti-slip strips are set longitudinally to improve the anti-slip performance of the front and rear soles. The anti-abrasion plates can protect the front, rear, and outer sides of the midsole, preventing the front, rear, and outer sides of the sole from being damaged and unsightly due to scratches. Several grooves are set to reduce the mass of the midsole, thereby reducing the overall mass of the sole and improving the conveyor belt during wear. Moreover, when the front, rear, or outer side of the sole is squeezed and scratched, the grooves can produce a certain amount of collapse deformation, buffering and reducing the squeezing force, thereby reducing the scratch force on the sole.

[0006] As a further optimization of this utility model, the front anti-slip sheet, the first anti-slip strip, the rear anti-slip sheet and the second anti-slip strip are respectively provided with a first anti-slip protrusion, a second anti-slip protrusion, a third anti-slip protrusion and a fourth anti-slip protrusion.

[0007] By adopting the above technical solutions, the anti-slip protrusions can enhance the wear resistance and anti-slip coefficient of the front anti-slip sheet, the first anti-slip strip, the rear anti-slip sheet, and the second anti-slip strip.

[0008] As a further optimization of this utility model, the first anti-slip protrusion, the second anti-slip protrusion, the third anti-slip protrusion and the fourth anti-slip protrusion are all V-shaped and have different orientations.

[0009] By adopting the above technical solution, the first, second, third, and fourth anti-slip protrusions are oriented in different directions, which can improve the anti-slip performance of the bottom layer in multiple directions and enhance the overall wear resistance of the sole.

[0010] As a further optimization of this utility model, the cross-sectional shape of the groove is D-shaped with the straight edge facing outward.

[0011] By adopting the above technical solution, the groove cross-section is set in a D shape. The straight edge of the groove deforms less when subjected to force, while the curved edge will deform to a certain extent when subjected to force. This allows the groove to be compressed and buffered inward after being subjected to force, reducing the situation where the sole of the shoe tilts outward.

[0012] As a further optimization of this utility model, the wear-resistant sheet is made of thermoplastic polyurethane.

[0013] Using the above technical solutions, thermoplastic polyurethane material has good elasticity, excellent physical properties, and good mechanical strength.

[0014] As a further optimization of this utility model, the front end of the central groove extends forward to the bottom of the middle, and the bottom of the middle is provided with a plurality of anti-slip blocks, which are arranged circumferentially with the front end of the central groove as the center.

[0015] By adopting the above technical solutions, the central groove and anti-slip blocks can increase the structural strength of the midsole, making it more resistant to torsion and deformation. Arranging the anti-slip blocks circumferentially can further improve the anti-slip performance of the midsole in multiple directions and enhance the overall abrasion resistance of the sole.

[0016] The beneficial effects of this utility model are as follows: setting front and rear anti-slip plates enhances the wear resistance of the front and rear sides of the sole; setting the first and second anti-slip strips longitudinally improves the anti-slip performance of the front and rear soles; setting anti-abrasion plates can protect the front, rear, and outer sides of the midsole, preventing the front, rear, and outer sides of the sole from being damaged and unsightly due to scratches; setting several grooves reduces the mass of the midsole, thereby reducing the overall mass of the sole and improving the conveyor belt during wear; and when the front, rear, or outer side of the sole is squeezed and scratched, the grooves can produce a certain amount of collapse deformation, buffering and reducing the squeezing force, thereby reducing the scratching force on the sole.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0022] See appendix Figure 1-3 The present embodiment of this utility model further includes: a wear-resistant lightweight rubber foam shoe sole, including a shoe sole body, the shoe sole body including a mid-bottom layer 11 and a bottom layer 12, the front end, the rear end and the outer side of the mid-bottom layer 11 are provided with anti-abrasion sheets 3, specifically, the anti-abrasion sheets 3 are made of thermoplastic polyurethane material.

[0023] The upper surface of the middle and bottom layer 11 has several grooves 9 spaced along the edge at the front end, rear end and outer side. Specifically, the cross-sectional shape of the grooves 9 is D-shaped and the straight edge faces outward.

[0024] The bottom layer 12 includes a front bottom 21, a middle bottom 22 and a rear bottom 23. The front bottom 21 is provided with a front anti-slip sheet 51 and a number of horizontally arranged first anti-slip strips 41. The number of first anti-slip strips 41 are arranged close to the outside and extend along the longitudinal direction. The rear bottom 23 is provided with a central groove 7, a rear anti-slip sheet 52 and a number of horizontally arranged second anti-slip strips 42. The number of second anti-slip strips 42 are arranged close to the outside and extend along the longitudinal direction.

[0025] Furthermore, the front anti-slip plate 51, the first anti-slip strip 41, the rear anti-slip plate 52, and the second anti-slip strip 42 are respectively provided with a first anti-slip protrusion 61, a second anti-slip protrusion 62, a third anti-slip protrusion 63, and a fourth anti-slip protrusion 64. The first anti-slip protrusion 61, the second anti-slip protrusion 62, the third anti-slip protrusion 63, and the fourth anti-slip protrusion 64 are all V-shaped and have different orientations.

[0026] Furthermore, the front end of the central groove 7 extends forward to the bottom 22, and the bottom is provided with several anti-slip blocks 8, which are arranged circumferentially with the front end of the central groove 7 as the center.

[0027] The principle of this utility model is as follows: setting a front anti-slip plate 51 and a rear anti-slip plate 52 enhances the wear resistance of the front and rear sides of the bottom layer 12; setting the first anti-slip strip 41 and the second anti-slip strip 42 longitudinally improves the anti-side slip performance of the front bottom layer 21 and the rear bottom layer 23; setting anti-slip protrusions can enhance the wear resistance and anti-slip coefficient of the surfaces of the front anti-slip plate 51, the first anti-slip strip 41, the rear anti-slip plate 52 and the second anti-slip strip 42; the first anti-slip protrusion 61, the second anti-slip protrusion 62, the third anti-slip protrusion 63 and the fourth anti-slip protrusion 64 have different orientations, which can improve the anti-slip performance of the bottom layer 12 in multiple directions and enhance the overall wear resistance of the sole.

[0028] The anti-abrasion plate 3 provides protection for the front, back and outer sides of the midsole 11, preventing the front, back and outer sides of the sole from being damaged and unsightly due to scratches. Moreover, the thermoplastic polyurethane material has good elasticity, good physical properties and good mechanical strength.

[0029] The presence of several grooves 9 reduces the mass of the mid-bottom layer 11, thereby reducing the overall mass of the sole and improving the conveyor belt during wear. Furthermore, when the front, rear, or outer side of the sole is subjected to compression and scratching, the grooves 9 can undergo a certain degree of collapse deformation, buffering and reducing the pressure and thus reducing the scratching force on the sole. The grooves 9 have a D-shaped cross-section. The straight edges of the grooves 9 deform less under force, while the curved edges deform to a certain extent under force, allowing the grooves 9 to compress and buffer inwards under force, reducing the tendency of the sole to tilt outwards.

[0030] The center groove 7 and the anti-slip block 8 can increase the structural strength of the midsole 22, and resist torsion and deformation. The anti-slip block 8 is arranged in a circumferential direction, which can further improve the anti-slip performance of the midsole 22 in multiple directions and enhance the overall wear resistance of the sole.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
