Description

Technical Field

[0001] The utility model relates to the technical field of rubber shoes, in particular to a lightweight rubber sole. Background Art

[0002] Shoes are one of the necessities of people's daily life. Wearing them on the feet can prevent the feet from being hurt and protect the feet. The traditional rubber shoe outsole has the advantages of strong wear resistance, good anti-slip properties, good softness, good extensibility and certain elasticity. Wearing them on the feet can well buffer the pressure of the feet and make the wearer more comfortable.

[0003] However, the unavoidable problem with rubber soles is that the weight of the rubber is too heavy, which easily increases the load on the wearer's feet when worn, thus affecting the wearer's experience. Therefore, in order to reduce the weight of rubber shoes on the market, multiple grooves are often opened inside the shoes, which not only ensures that the soles have sufficient support, but also reduces the overall weight of the shoes.

[0004] However, because the grooves are opened on the sole to make it lighter, as time goes by, once the sole is damaged due to long-term friction, water can directly enter the shoe and soak the insole. In addition, most rubber soles are made in one piece, which is not easy to dry inside the shoe. At the same time, since the inner sole of the shoe is smooth all around, the insole is easy to shift during wearing, affecting the wearer's wearing experience. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0007] A lightweight rubber sole comprises a base, wherein the base is fixedly connected with a bottom upper around the periphery, a grid layer is fixedly connected with the bottom of the base, and an insole layer is arranged on the top of the grid layer;

[0008] The grid layer comprises an outer frame, wherein a reinforcing rib is transversely penetrated and fixedly connected inside the outer frame, and a limiting rib is longitudinally penetrated and fixedly connected inside the outer frame;

[0009] The insole layer comprises a forefoot pad and a rear foot pad, and a connecting pad is fixedly connected between the forefoot pad and the rear foot pad.

[0010] As a preferred solution of the lightweight rubber sole described in the utility model, the grid layer is sewn and fixed to the upper on all sides, and the bottom of the grid layer is welded to the inner bottom of the base. By arranging the grid layer inside the sole, the overall weight of the sole is reduced.

[0011] As a preferred solution of the lightweight rubber sole described in the utility model, a front limiting hole and a rear limiting hole are commonly provided between the reinforcing ribs and the limiting ribs, and limiting blocks corresponding to the front limiting hole and the rear limiting hole are fixedly connected to the bottom of the forefoot pad and the rear foot pad respectively, and the limiting blocks are correspondingly plugged into the front limiting hole and the rear limiting hole. By plugging the limiting blocks at the bottom of the insole layer into the front limiting hole and the rear limiting hole, the insole layer is easily positioned, so that the position of the insole is ensured to be stable when the wearer is wearing it.

[0012] As a preferred solution of the lightweight rubber sole described in the utility model, the insole layer is tightly fitted with the inner wall of the sole. When the sole is damaged, water enters the grille layer. By plugging the limiting blocks and limiting holes, the insole layer is tightly fitted with the sole, which plays a double sealing role, thereby preventing water from entering the shoe and rising to wet the upper surface of the insole layer.

[0013] As a preferred solution of the lightweight rubber sole described in the utility model, the insole layer includes a surface cloth layer and a bottom rubber layer. The upper surface cloth is convenient for providing a better wearing feeling for the user, and the bottom rubber layer is convenient for cooperating with the grid layer, which can not only fix the insole layer, but also play a waterproof and insulating role.

[0014] As a preferred solution of the lightweight rubber sole described in the utility model, the base, the upper and the grille layer are all made of rubber material, the outer sides of the base and the upper are made of vulcanized rubber material, and the grille layer and the inner side wall of the upper are made of the same natural rubber material.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model improves the stability of the insole in the rubber sole through the mutual cooperation between the base, the grid layer and the insole layer, which is not easy to shift during wearing, thereby improving the wearing feeling of the wearer; at the same time, the split sole design is adopted, and the insole is not easy to get damp under the rubber sealing effect inside the shoe body. Even if it gets damp, it can be directly taken out and dried separately, and the drying speed is fast. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1-3 The utility model provides a lightweight rubber sole, comprising a base 1, and a bottom upper 2 is fixedly connected to the base 1 around the periphery.

[0026] The bottom of the base 1 is fixedly connected with a grid layer 3, and the top of the grid layer 3 is provided with an insole layer 4, which includes a surface cloth layer and a bottom rubber layer. The upper surface cloth is convenient for providing a better wearing feeling for the user, and the bottom rubber layer is convenient for cooperating with the grid layer 3, which can not only fix the insole layer 4, but also play a waterproof and insulating role. At the same time, the insole layer 4 is tightly fitted with the inner wall of the bottom 2. When the sole is damaged, water enters the grid layer 3. By plugging the limit block 7 and the limit hole, the insole layer 4 is tightly fitted with the bottom 2, which plays a double sealing role, thereby preventing water from entering the shoe and rising to wet the upper surface of the insole layer 4.

[0027] In this embodiment, the base 1, the bottom 2 and the grille layer 3 are all made of rubber material, the outer sides of the base 1 and the bottom 2 are made of vulcanized rubber material, and the inner side walls of the grille layer 3 and the bottom 2 are made of the same natural rubber material.

[0028] The grid layer 3 is sewn and fixed to the sole upper 2 on all sides, and the bottom of the grid layer 3 is welded to the inner bottom of the base 1. By arranging the grid layer 3 inside the sole, the overall weight of the sole can be reduced.

[0029] The grid layer 3 comprises an outer frame 301 , wherein a reinforcing rib 302 is passed through and fixedly connected to the inner part of the outer frame 301 in a transverse direction, and a limiting rib 303 is passed through and fixedly connected to the inner part of the outer frame 301 in a longitudinal direction.

[0030] The insole layer 4 includes a forefoot pad 401 and a rear foot pad 402 , and a connecting pad 403 is fixedly connected between the forefoot pad 401 and the rear foot pad 402 .

[0031] Among them, a front limiting hole 5 and a rear limiting hole 6 are commonly provided between the reinforcing rib 302 and the limiting rib 303, and limiting blocks 7 corresponding to the front limiting hole 5 and the rear limiting hole 6 are fixedly connected to the bottom of the forefoot pad 401 and the rear foot pad 402 respectively, and the limiting blocks 7 are correspondingly plugged into the front limiting holes 5 and the rear limiting holes 6. By plugging the limiting blocks 7 at the bottom of the insole layer 4 into the front limiting holes 5 and the rear limiting holes 6, it is convenient to position the insole layer 4, so that the position of the insole can be kept stable when the wearer is wearing it.

[0032] When in use, the insole layer 4 is directly placed into the sole 2, and the bottom limiting block 7 of the insole layer 4 is inserted into the front limiting hole 5 and the rear limiting hole 6. When the user wears the shoe, the insole layer 4 is limited by the grid layer 3 and is not easily displaced, thereby ensuring the wearer's usage experience.

[0033] At the same time, when the lightweight shoe base 1 is damaged, water enters the grid layer 3, and the rubber layer at the bottom of the insole layer 4 and the rubber on the inner wall of the sole 2 fit closely together, which together play a certain waterproof sealing effect on the inner bottom of the shoe body, thereby effectively reducing the direct contact between water and the top surface fabric of the insole layer 4, ensuring the wearer's wearing experience. Of course, even if the top surface of the insole layer 4 is wet, the insole layer 4 can be directly pulled out of the shoe body as a whole, and the shoe base 1 and the insole layer 4 can be dried separately, which is easier to dry than traditional one-piece rubber shoes.

[0034] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
