Technical Field

[0001] The utility model relates to the technical field of soles, in particular to a sole with adjustable sole thickness. Background Art

[0002] There are many types of sole materials, which can be divided into natural sole materials and synthetic sole materials. Natural sole materials include natural sole leather, bamboo, wood, etc., and synthetic sole materials include rubber, plastic, rubber-plastic composite materials, recycled leather, elastic cardboard, etc. Shoes are a necessity in people's lives. For visual beauty, women usually choose high heels, but wearing high heels for a long time will cause leg pain. Therefore, it is worth studying to develop a shoe whose sole can be changed at any time according to one's wishes;

[0003] In the prior art, for example, announcement No. CN202800340U proposes a shoe with a variable sole thickness. The technical solution relates to a shoe with a variable sole thickness, including an upper and a sole, wherein a zipper is provided on the side wall of the sole, and the interior of the sole is a cavity, wherein a pad is movably provided in the cavity, and the pad is in the shape of a sole and slightly smaller than the size of the sole; a pad is movably provided inside the sole, and the pad can be taken out at any time according to the wearer's wishes, so as to adjust the thickness of the sole, thereby solving the problem of leg soreness caused by long-term wearing of high-heeled shoes, wherein the pad is in the shape of a sole and slightly smaller than the size of the sole, thereby increasing the comfort of the shoe, and the shoe has a simple structure, is convenient and practical;

[0004] However, the existing shoes directly connect the sole to the upper through a zipper, and the pad is taken out by opening the zipper. Such a structure is not only not strong enough, but also after the pad is taken out, the top and bottom of the sole cannot be directly connected, which is easy to increase the wear of the sole when walking and make the wearer feel uncomfortable.

[0005] In order to solve the above problems, the present application proposes a sole with adjustable sole thickness. Utility Model Content

[0006] The utility model is intended to provide a sole with adjustable sole thickness, which is mainly used to solve the problem that the existing shoes directly connect the sole to the upper through a zipper, and the pad is taken out and placed by opening the zipper. Such a structure is not only not strong enough, but also after the pad is taken out, the top and bottom of the sole cannot be directly connected, which is easy to increase the wear of the sole when walking and make the wearer feel uncomfortable.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A sole with adjustable sole thickness comprises an upper and a sole fixedly connected to the bottom of the upper, the bottom of the sole is connected to a thickening pad, the top of the thickening pad is fixedly connected to a positioning assembly, a plurality of screws penetrate the thickening pad, and the screws are threadedly connected to the thickening pad, and a plurality of threaded holes matching the screws are provided at the bottom of the sole.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When people need to increase the thickness of the sole when wearing the shoes, they place the thickening pad on the sole, then install multiple screws on the thickening pad and tighten them to make them threadedly connected with the threaded holes at the bottom of the sole, so that the thickening pad can be fixed on the sole, and the shoes can be used normally. The thickening pad, the sole and the screws are all made of rubber material, thereby ensuring the normal use of the shoes. After removing the screws, the thickening pad can be removed from the sole, and the thickness of the sole can be adjusted.

[0011] 2. Beneficial effects: The thickening pad is connected to the sole by a plurality of screws, which not only makes the connection between the thickening pad and the sole more firm, but also makes it convenient for people to disassemble the thickening pad, thereby making it more convenient to adjust the thickness of the sole. The positioning assembly provided on the thickening pad allows people to better position the thickening pad when installing it. In this way, after the thickening pad is placed on the sole, the screws on the thickening pad can be just aligned with the threaded holes on the sole, thereby making the installation of the thickening pad more convenient.

[0012] Preferably, a symmetrical positioning block is fixedly connected to the top of the thickening pad, a positioning groove matching the positioning block is opened at the bottom of the sole, and a dustproof component is fixedly connected to the top of the inner wall of the positioning groove. When installing the thickening pad, the positioning block on the thickening pad needs to be inserted into the positioning groove on the sole. When the thickening pad fits the sole, the screws can be installed on the thickening pad and tightened to be threadedly connected to the threaded hole at the bottom of the sole. The shoe can then be used normally, which makes the installation of the thickening pad more convenient.

[0013] Preferably, the dustproof component includes a spring fixedly connected to the top of the inner wall of the positioning groove, and the lower end of the spring is fixedly connected to the dustproof block, which is slidably connected to the inner wall of the positioning groove. When installing the thickening pad, after the positioning block on the thickening pad is inserted into the positioning groove on the sole, the positioning block will squeeze the dustproof block and move it into the positioning groove, and at the same time squeeze the spring to put it in a compressed state. After the screws are installed, the shoe can be used normally. After the screws are removed, the dustproof block will push the thickening pad a certain distance under the action of the spring, which makes the disassembly of the thickening pad more convenient. After the thickening pad is removed, the dustproof block is located at the opening of the positioning groove under the action of the spring, which can effectively prevent a large amount of dust from entering the positioning groove during use of the shoe, thereby effectively ensuring the normal use of the shoe.

[0014] Preferably, a magnet is fixedly connected to the top of the positioning block, and an iron sheet attracted to the magnet is fixedly connected to the bottom of the dustproof block. When installing the thickening pad, after the positioning block on the thickening pad is inserted into the positioning groove on the sole, the magnet on the positioning block will be attracted to the iron sheet on the dustproof block, thereby realizing the pre-installation of the thickening pad. After the screws are installed, the shoes can be used normally, which makes the installation of the thickening pad more convenient.

[0015] Preferably, there are four springs, and the springs are symmetrically arranged at the four corners of the top of the inner wall of the positioning groove. By setting the number of springs inside the positioning groove to four, the four springs can exert a greater thrust on the dust block, so that the dust block can be more stable when located at the opening of the positioning groove under the action of the springs, thereby further preventing dust from entering the interior of the positioning groove.

[0016] Preferably, the screw is an embedded hexagonal setting, and the lower end surface of the screw does not exceed the bottom of the thickened pad. After the screw is installed, the lower end surface of the screw does not exceed the bottom of the thickened pad, so that it will not bulge out and cause wear. The screw is an embedded hexagonal setting. The screw with an embedded hexagonal setting can rotate better during installation, reducing the possibility of slip angle.

[0017] Preferably, the corners at the opening of the positioning groove are all chamfered. By setting the corners at the opening of the positioning groove as chamfers, it is easier to insert the positioning block into the positioning groove, thereby making the installation of the thickening pad easier.
