Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, and in particular to a shoe sole with thickness adjustment function. Background Technology

[0002] There are many types of materials used for shoe soles, which can be divided into natural and synthetic materials. Natural sole materials include natural leather, bamboo, and wood, while synthetic sole materials include rubber, plastics, rubber-plastic composites, recycled leather, and flexible cardboard. With the continuous development of society, people's requirements for shoes are also increasing. For example, some people prefer thicker soles for rubber shoes for the elderly, while others prefer thinner soles. Others prefer soles that can be easily adjusted to different road conditions. Currently, the sole thicknesses on the market are all fixed, which makes it difficult to meet the different thickness needs of different wearers.

[0003] Based on the above background, a sole with adjustable thickness is proposed, which can switch the thickness according to personal preference or different road conditions to improve wearing comfort. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a shoe sole with thickness adjustment function.

[0006] To achieve the above objectives, the technical solution of this utility model is: a shoe sole with thickness adjustment function, comprising: a shoe sole body, an insole, an adjusting lower sole, a bolt, a threaded sleeve, and an insertion hole. The threaded sleeve is installed on the shoe sole body. The adjusting lower sole has several layers stacked on the underside of the shoe sole body. An insertion hole is provided on the adjusting lower sole for the threaded sleeve to pass through. The diameter of the insertion hole is smaller than that of the threaded sleeve. The bolt is threadedly connected to the threaded sleeve. The insole is placed on the shoe sole body and covers the bolt.

[0007] As a preferred option, the insoles are made of a soft material.

[0008] Preferably, threaded sleeves are installed on both the forefoot and heel of the sole.

[0009] As a preferred option, the threaded sleeve has several recessed holes.

[0010] Preferably, an elastic ring is inserted into the socket.

[0011] Preferably, the inner wall of the elastic ring has a raised ring.

[0012] Preferably, the elastic ring engages with the concave hole.

[0013] Preferably, the adjusting lower sole is fixed to the underside of the shoe sole body by inserting a threaded sleeve through the insertion hole.

[0014] Preferably, several layers of adjustable bottoms are connected by Velcro.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows: When it is necessary to adjust the thickness of the sole, an adjustment undersole is directly torn off downwards. The adjustment undersole is detached from the threaded sleeve by external force, and the thickness of the adjustment undersole remaining on the threaded sleeve becomes thinner. Since tearing off the adjustment undersole will expose part of the threaded sleeve and make walking inconvenient, the threaded sleeve can be rotated. Under the action of the bolt, the threaded sleeve moves upward until it retracts upward and is flush with the adjustment undersole under the sole body. This process can achieve the adjustment of the sole thickness by adjusting the addition or subtraction of the undersole. It has the function of conveniently switching the sole thickness to adapt to different road conditions, enhancing applicability and improving wearing comfort.

[0028] The following detailed description of the embodiments of this utility model, in conjunction with the accompanying drawings, will provide a thorough understanding of how this utility model uses technical means to solve technical problems and achieve technical effects, enabling its implementation. It should be noted that, provided there is no conflict, the various embodiments and features within them can be combined with each other, and all resulting technical solutions are within the protection scope of this utility model.

[0029] Furthermore, numerous specific details are set forth in the following description for illustrative purposes to provide a thorough understanding of the embodiments of this invention. However, it will be apparent to those skilled in the art that this invention may be practiced without the specific details or particular methods described herein.

[0030] Please see Figure 1-5 This utility model provides a shoe sole with thickness adjustment function, including: shoe sole body 1, shoe insole 2, adjusting lower sole 3, bolt 4, threaded sleeve 5, and insertion hole 6. The threaded sleeve 5 is installed on the shoe sole body 1. The adjusting lower sole 3 is provided with several layers and is stacked on the lower side of the shoe sole body 1. The adjusting lower sole 3 has an insertion hole 6 for the threaded sleeve 5 to pass through the lower side. The diameter of the insertion hole 6 is smaller than that of the threaded sleeve 5. The bolt 4 is threadedly connected to the threaded sleeve 5. The shoe insole 2 is placed on the shoe sole body 1 and covers the bolt 4.

[0031] When adjusting the sole thickness, simply tear off the adjusting lower sole 3. The adjusting lower sole 3 will detach from the threaded sleeve 5 under external force, and the adjusting lower sole 3 remaining on the threaded sleeve 5 will become thinner. Since tearing off the adjusting lower sole 3 will expose part of the threaded sleeve 5 and make walking inconvenient, the threaded sleeve 5 can be rotated. Under the action of the bolt 4, the threaded sleeve 5 will move upward until it retracts upward and is flush with the adjusting lower sole 3 under the sole body 1. Then, place the insole 2 on the sole body 1 to achieve the sole thickness adjustment function.

[0032] According to some embodiments of this application, the insole 2 may optionally be made of a soft material. This makes it more comfortable for the wearer's foot to rest on the insole 2 and provides separation from the bolt 4.

[0033] According to some embodiments of this application, optionally, threaded sleeves 5 are installed on both the forefoot and heel of the sole body 1. This makes the adjusting undersole 3 more stable on the underside of the sole body 1.

[0034] According to some embodiments of this application, optionally, the threaded sleeve 5 has several recessed holes 7, and an elastic ring 8 is inserted into the insertion hole 6, which engages with the recessed hole 7. When it is necessary to increase the thickness of the sole and add an adjustable undersole 3, the insertion hole 6 on the adjustable undersole 3 is connected to the threaded sleeve 5. During connection, the elastic ring 8 is deformed by the compression of the threaded sleeve 5, and then returns to engage with the recessed hole 7, thus completing the fixed connection between each layer of adjustable undersole 3, which has the function of limiting each other and preventing them from easily separating.

[0035] According to some embodiments of this application, optionally, the inner wall of the elastic ring 8 has a convex ring. The convex ring is engaged with the concave hole 7, which enhances the fastening effect; it can only be removed by external force.

[0036] According to some embodiments of this application, optionally, the adjusting lower sole 3 is fixed to the lower side of the sole body 1 by inserting a threaded sleeve 5 through the insertion hole 6. Since the diameter of the threaded sleeve 5 is larger than that of the insertion hole 6, the threaded sleeve 5 is squeezed into the insertion hole 6. After squeezing, the inner wall of the insertion hole 6 will be tightly attached to the threaded sleeve 5, and the adjusting lower sole 3 will be tightly attached to the lower side of the sole body 1.

[0037] According to some embodiments of this application, optionally, several layers of adjustable bottoms 3 are connected by Velcro. This provides a certain degree of adhesion between the adjustable bottoms 3.
