Description

Technical Field

[0001] This utility model belongs to the field of footwear technology, and in particular relates to a shoe sole with a changeable shape. Background Technology

[0002] In the footwear manufacturing industry, as people's functional demands for shoes continue to increase, the single structure and fixed shape of traditional soles are gradually failing to meet diverse usage scenarios. In daily walking, sports, special working environments, and different road conditions, people expect soles to have adjustable shapes to provide better comfort, stability, and adaptability.

[0003] When driving, the heel of high heels reduces the contact area between the foot and the pedal. When pressing the pedal, the foot cannot fully conform to the pedal as it can with flat shoes. When pressing the brake pedal, it may be difficult to accurately control the pressure applied, which is very dangerous. In daily life, if you need to drive while wearing high heels, you must change your shoes, which is very inconvenient. Therefore, we provide a shape-changing sole to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a shape-changing sole that solves the problem that existing shoe heels cannot be used in various environments through the cooperation of the first connecting block and the limiting member.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a shape-changing shoe sole, comprising a sole plate and a heel. The heel is located at the bottom of the sole plate.

An elastic support rod is fixedly connected to one side of the first slider. Both the spring and the elastic support rod are located in the cavity of the second through hole. A second slider is fixedly connected to one side of both the spring and the elastic support rod. The second slider is slidably connected to the surface of the through groove. The sole plate and the supporting plate are glued together. The first through hole is located at the top of the through groove. The first connecting block is located on the opposite side of the connecting member and is glued together with the heel.

[0007] The present invention is further configured such that a first limiting block is fixedly connected to the bottom of the first groove, and a second limiting block is fixedly connected to one side of the heel, with the first limiting block located at the top of the second limiting block and the second limiting block located at the top of one side of the heel.

[0008] The present invention is further configured such that a movable block is fixedly connected to the bottom of the first groove, the movable block is snapped into the heel, and two movable blocks are provided, located on both sides of the bottom of the first groove respectively.

[0009] The present invention is further configured such that a connecting rod is fixedly connected to the bottom of the supporting base plate, and a rubber pad is connected through the bottom of the connecting rod, and the connecting rod is glued to the supporting base plate.

[0010] The present invention is further configured such that a second groove is provided on the top of the rubber pad, and a second connecting block is fixedly connected to the bottom of the support base plate.

[0012] The present invention has the following beneficial effects.

[0013] 1. The first connecting block and its connecting structure of this utility model are used to transform the shape of the shoe sole, which is suitable for a variety of usage environments. The setting of the first limiting block and the second limiting block restricts the range of motion of the heel, preventing the heel from shifting or shaking excessively during the shape change process, and ensuring that the shoe sole can maintain stable support under various conditions.

[0014] 2. The protective sleeve on the inner surface of the third through hole of this utility model can reduce friction and wear between the heel and the rubber pad, prevent damage to the components due to long-term use, thereby extending the overall service life of the sole, reducing the frequency of sole replacement, saving costs and resources, and also playing a certain role in fixing and limiting the heel. The stable connection and reasonable design between the various components also reduce the occurrence of situations where the performance of the sole is affected by loose or damaged components, ensuring that the sole can always maintain a good working condition during long-term use.

[0022] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0023] Please see Figure 1-5 This utility model is a shape-changing shoe sole, including a sole plate 1 and a heel 2. The heel 2 is located at the bottom of the sole plate 1. A supporting base plate 3 is fixedly connected to the bottom of the sole plate 1. A first groove is opened at the bottom of the supporting base plate 3. A limiting member 4 is fixedly connected to the bottom of the first groove. A first through hole 5 is opened on one side of the limiting member 4. A through groove 6 is opened on one side of the limiting member 4. A rotating rod 7 is connected through the first through hole 5. A first connecting block 8 is connected through the rotating rod 7 on one side. The bottom of the first connecting block 8 is fixedly connected to the top of the heel 2. A second through hole 9 is opened on one side of the first connecting block 8. A first slider 10 is connected through the inner cavity of the through groove 6. A spring 11 is fixedly connected to one side of the first slider 10. An elastic support rod 12 is fixedly connected to one side of the first slider 10. The spring 11 and the elastic support rod 12 are both located in the inner cavity of the second through hole 9. A second slider 13 is fixedly connected to one side of both the spring 11 and the elastic support rod 12. The second slider 13 is slidably connected to the inner surface of the through groove 6.

[0024] Specifically: the shoe heel 2 moves, causing the first connecting block 8 to move. The limiting member 4 limits the movement trajectory of the first connecting block 8. The movement of the first connecting block 8 causes the rotating rod 7 to rotate. The first through hole 5 limits the movement trajectory of the rotating rod 7. The movement of the first connecting block 8 causes the spring 11 and the elastic support rod 12 to move. The second through hole 9 limits the movement trajectory of the spring 11 and the elastic support rod 12. The movement of the spring 11 and the elastic support rod 12 causes the first slider 10 to move. The first slider 10 and the second slider 13 compress the spring 11 and the elastic support rod 12. When the first slider 10 and the second slider 13 move to the designated position, the spring 11 and the elastic support rod 12 release elastic potential energy, pushing the second slider 13 to move. The second slider 13 moves and locks into the through groove 6, thus fixing the position of the shoe heel 2. Example 2

[0025] Please see Figure 1-5 Based on Embodiment 1, a first limiting block 14 is fixedly connected to the bottom of the first groove, a second limiting block 15 is fixedly connected to one side of the heel 2, a movable block 16 is fixedly connected to the bottom of the first groove, the movable block 16 is snapped into the heel 2, a connecting rod 17 is fixedly connected to the bottom of the supporting base plate 3, a rubber pad 18 is connected through the bottom of the connecting rod 17, a second groove is opened on the top of the rubber pad 18, a second connecting block 19 is fixedly connected to the bottom of the supporting base plate 3, the second connecting block 19 is snapped into the second groove, a third through hole is opened at the bottom of the rubber pad 18, the third through hole is connected through the heel 2, and a protective sleeve 20 is fitted on the inner surface of the third through hole.

[0026] Specifically: the movement of heel 2 causes the second limiting block 15 to move. The first limiting block 14 and the second limiting block 15 cooperate to limit the movement trajectory of heel 2. When heel 2 is retracted into the inner cavity of the first groove, heel 2 is pushed forcefully, and heel 2 is locked with the movable block 16. Rubber pad 18 increases friction, reduces the impact during use, and improves the comfort of walking. After heel 2 is retracted, rubber pad 18 is moved. Connecting rod 17 limits the movement trajectory of rubber pad 18. After the second groove and the second connecting block 19 are aligned, they are snapped together to fix the position of rubber pad 18. When heel 2 is lowered, heel 2 is aligned with the third through groove 6. The size of the protective sleeve 20 is designed to fit heel 2 and the second limiting block 15, so that heel 2 can be firmly locked.

[0027] The working principle of this utility model is as follows: The top of the heel 2 is connected to the rotating rod 7 through the first connecting block 8. The rotating rod 7 passes through the first through hole 5, so that the heel 2 can rotate at a certain angle around the rotating rod 7. During the rotation of the heel 2, the spring 11 and the elastic support rod 12 in the second through hole 9 drive the first slider 10 and the second slider 13 to move, so that the spring 11 and the elastic support rod 12 will stretch and deform in the second through hole 9. When the first connecting block 8 moves to the designated position, the spring 11 and the elastic support rod 12 push the second slider 13 to move. The second slider 13 is locked with the through groove 6, fixing the position of the heel 2.
