TECHNICAL FIELD
[0001] The utility model relates to the technical field of shoes, in particular to a lifting-free shock-absorbing shoe sole. BACKGROUND
[0002] In daily life, as a necessity for people to walk, run and carry out various activities, the rationality of the design of shoes is directly related to the comfort and convenience of the wearer. Most of the existing shoe models fail to fully consider the balance between ergonomics and convenience during design, especially in the treatment of the heel part. Traditional sole design often lacks sufficient elasticity or ingenious mechanical structure, so that the wearer has to rely on hand power to lift the heel when wearing shoes to overcome the friction between the shoe opening and the ankle, and then put the foot into the shoe. This process is not only cumbersome, increasing the time cost of putting on and taking off shoes, but also an additional burden for those who have limited hand power, insufficient joint flexibility or are in a hurry.
[0003] In addition, frequent manual lifting can cause unnecessary wear and tear on the structure of the shoe, such as deformation of the heel part, shortening the service life of the shoe, and also affecting the appearance and overall wearing experience of the shoe. In the long run, this unreasonable design may also have a potential impact on the wearer's foot health, such as foot sprain caused by difficulty in putting on and taking off shoes or pain caused by improper posture. SUMMARY
[0004] In view of the deficiencies of the prior art, the utility model provides a lifting-free shock-absorbing shoe sole, which solves the problems raised in the background art.
[0005] To achieve the above purpose, the utility model realizes the following technical scheme: a lifting-free shock-absorbing shoe sole, comprising a shoe sole body, both sides of the shoe sole body are connected with a wrapping part, the tail ends of the wrapping parts are connected with an elastic ring, the elastic ring can be elastically deformed, and a hollow part is reserved between the heel part of the shoe sole body and the elastic ring.
[0006] Further, the upper surface of the shoe sole body is provided with a recessed part, and the height of the recessed part is lower than the height of the edge of the shoe sole body.
[0007] Further, the wrapping part comprises wrapping part one and wrapping part two, and the shoe sole body, wrapping part one, wrapping part two and the elastic ring form an integral whole.
[0008] Further, the elastic ring is inclined as a whole, and the inclination angle of the elastic ring and the opening angle of the hollow part are 10-45°.
[0009] Furthermore, the elastic ring has a "U" shaped structure, and the inner side of the elastic ring is provided with a beveled part, which slopes from the top to the bottom.
[0010] Furthermore, the bottom of the sole body is provided with several shock-absorbing cavities, and the inner diameter of the several shock-absorbing cavities gradually increases from the sole to the heel.
[0011] Furthermore, the bottom of the sole body is provided with several support columns, which are alternately distributed with several shock-absorbing cavities.
[0012] This invention provides a lift-free, shock-absorbing shoe sole. Compared with the prior art, it has the following advantages:
[0013] This hands-free, shock-absorbing sole features an integrated elastic ring, eliminating the need for lifting the heel and significantly improving the ease of putting on and taking off shoes. Specifically, the sole design utilizes a U-shaped elastic ring combined with a slanted surface. During shoe insertion, the heel easily steps down, pushing the elastic ring to deform. The ring then automatically rebounds after the heel passes over it, eliminating the need for hand assistance. This design not only simplifies the process and reduces physical exertion, but also ensures structural stability and durability by providing space for the elastic ring to deform through the hollowed-out sections. Furthermore, the clever combination of the shock-absorbing cavity and support pillars further enhances the sole's shock absorption performance, providing a more comfortable and safer walking experience.

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0021] Please refer to Figures 1-5 The utility model provides a technical scheme: a lifting-free damping shoe sole is formed by a shoe sole main body 1, a wrapping part 2, an elastic ring 3, a hollow part 4, a plurality of damping cavities 5 and a plurality of support columns 6, the upper surface of the shoe sole main body 1 is provided with a recessed part 11, the height of the recessed part 11 is lower than the height of the edge of the shoe sole main body 1, the whole shoe sole is integrally formed through injection molding process, that is to say, the shoe sole main body 1, the wrapping part 2, the elastic ring 3, the hollow part 4, the plurality of damping cavities 5 and the plurality of support columns 6 are a whole, the wrapping part 2 is formed by wrapping part one 21 and wrapping part two 22, wrapping part one 21 and wrapping part two 22 correspond to different side areas of the foot respectively and are also attached to the sides of the foot, so as to provide powerful support for the foot, the elastic ring 3 can be elastically deformed, and in order to facilitate wearing of the shoe, the elastic ring 3 is provided as a "U" shaped structure, and the inner side of the elastic ring 3 is provided with an inclined surface part 31, the inclined surface part 31 is inclined from the top to the bottom, the inclination angle of the elastic ring 3 and the opening angle of the hollow part 4 are 10-45 DEG, when the shoe is worn, the heel part will step down the elastic ring 3, so that the elastic ring 3 is deformed, and the design of the hollow part 4 is to reserve space for the deformation of the elastic ring 3, the tail end of the heel part is inclined from bottom to top, that is to say, the sole of the heel part is convex, so when the sole steps down the elastic ring 3, because of the deformation of the elastic ring 3 and the automatic recovery, when the convex position of the heel part passes the elastic ring 3, the elastic ring 3 is no longer pressed by the heel part, so the elastic ring 3 can automatically rebound, so as to realize lifting-free of the shoe heel.
