DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0032] Referring to Figure 1 , Figure 4 and Figure 5 , the utility model provides an embodiment: a kind of rebound tester for sports shoes, including shell 1, scale column 3 is fixedly connected in shell 1 interior, scale column 3 requires to have higher hardness and dimensional stability, adjusting assembly is arranged on the outer wall of scale column 3, shock absorbing assembly is arranged in the bottom of shell 1;

[0033] Adjusting assembly includes collar 16, collar 16 can select polytetrafluoroethylene material, collar 16 is slidably connected in the outer wall of scale column 3, connecting block 17 is fixedly connected to the outer wall of scale column 3, connecting block 17 can adopt aluminium alloy material, while reducing overall weight under the condition of guaranteeing certain intensity, eccentric wheel 18 is rotatably connected to the side wall of connecting block 17, wrench 20 is fixedly connected to the outer wall of eccentric wheel 18, wrench 20 can adopt engineering plastics material, clamping plate 19 is slidably connected to the outer wall of scale column 3, clamping plate 19 can select brass material, clamping plate 19 is slidably connected in the interior of connecting block 17, the side wall of clamping plate 19 is arranged on the outer wall of eccentric wheel 18, first connecting column 4 is fixedly connected to the outer wall of collar 16;

[0034] Specifically, when the relevant test work is carried out by using the sports shoe rebound tester, first of all, the height adjusting device of the tester needs to be operated. Specifically, the wrench 20 located at a specific position needs to be manually pulled. After the wrench 20 is stressed, the force is transmitted to the eccentric wheel 18, so as to drive the eccentric wheel 18 to rotate around its axis. During the rotation of the eccentric wheel 18, a specific mechanical relationship is formed between the eccentric wheel 18 and the side wall of the connecting block 17. At the same time, the clamping plate 19 arranged on the outer wall of the eccentric wheel 18 will displace with the rotation of the eccentric wheel 18, until it abuts against the outer wall of the scale column 3, forming a stable limiting state. The connecting block 17 can smoothly slide in the specific track or cavity structure matched therewith. On this basis, the sleeve ring 16 is further pulled, and the sleeve ring 16 moves up and down along the outer wall of the scale column 3. Since the outer wall of the scale column 3 is carefully provided with clear and explicit scale marks, the operator can intuitively and accurately judge the position height of the sleeve ring 16 according to these scales, so as to facilitate manual accurate height adjustment of the relevant components of the tester according to the test requirements, and finally achieve the good effect of facilitating flexible height adjustment to adapt to different sports shoe test requirements, laying a solid foundation for subsequent accurate acquisition of the rebound data of the sports shoes.

[0035] With reference to Figure 1 And Figure 3 The first connecting column 4 is fixedly connected with the second connecting column 9 at the bottom, and the first connecting column 4 and the second connecting column 9 mainly play the role of connecting and transmitting force, and need to have certain strength and toughness, and can be selected from aluminum alloy material. The first gear 10 is fixedly connected to the outer wall of the second connecting column 9, and the first sliding column 11 is slidably connected inside the first gear 10. The first sliding column 11 needs to have good wear resistance and certain strength, and can be selected from chrome-plated alloy steel material. The third connecting column 12 is fixedly connected to the bottom of the first sliding column 11, and also plays the role of connecting and supporting, and aluminum alloy material is more suitable. The first moving plate 13 is slidably connected inside the third connecting column 12, and can be made of aluminum alloy material. The clamping plate 15 is fixedly connected to the bottom of the first moving plate 13. The second gear 14 is rotatably connected to the top of the third connecting column 12, and is engaged with the first gear 10. The handle 8 is fixedly connected inside the second gear 14;

[0036] Specifically, when the clamping operation of the sports shoes is carried out to carry out the subsequent rebound test, first, the clamping mechanism of the tester needs to be operated, and the handle 8 at a specific position is manually rotated. The handle 8 will effectively transmit the rotation power to the second gear 14 connected thereto during rotation, so as to drive the second gear 14 to stably rotate around its axis. Because there is a precise meshing relationship between the second gear 14 and the first gear 10, the rotation of the second gear 14 will drive the first gear 10 meshed therewith to rotate. When the first gear 10 rotates, the first sliding column 11 nested in the inside thereof is driven to make the first sliding column 11 smoothly slide in the specific track or cavity structure designed in the inside of the first gear 10. Then, with the movement of the first sliding column 11, the first moving plate 13 connected to the bottom thereof will be pushed to start moving. In this process, the first moving plate 13 will slide in the inside of the third connecting column 12, and the third connecting column 12 can provide stable support for the first moving plate 13 to ensure the stability and directionality of the movement process. The movement of the first moving plate 13 will further drive the clamping plate 15 installed at the bottom thereof to rotate. When the clamping plate 15 rotates to the appropriate angle, it will be in close contact with the shoe edge and stably clamp the shoe edge, thereby realizing the effect of supporting the inner shoe edge, effectively fixing the sports shoes at the specified position of the tester, creating favorable conditions for accurate rebound test, and ensuring the stability and reliability of the position of the shoes during the test process.

[0037] With reference to Figure 1 and Figure 3 The shock absorbing assembly comprises a second support plate 6 which plays a key role in connection and support. The material of the second support plate 6 can be aluminum alloy. The second support plate 6 is fixedly connected to the bottom of the shell 1. The sidewall of the second support plate 6 is provided with a spring 5, one end of which is fixedly connected to the bottom of the second support plate 6. The top of the second support plate 6 is provided with a first support plate 2 which is connected to the spring 5 and directly or indirectly contacts the test sample. The first support plate 2 can be made of stainless steel. The other end of the spring 5 is fixedly connected to the top of the first support plate 2. The inner wall of the spring 5 is fixedly connected with a fixing column 7, and the outer wall of the fixing column 7 is arranged in the inside of the first support plate 2. The shock absorbing assembly reduces the attraction of the device caused by rebound during the test, thereby improving the test accuracy.

[0038] Specifically, in the specific operation process of carrying out the sports shoes rebound test, when preparing for the test, first of all, the sole part of the sports shoes needs to be accurately placed and gently pressed on the inner wall of the shell 1 at a specific position. With the contact of the sole with the inner wall of the shell 1 and the application of pressure, the shell 1 will produce a corresponding displacement change due to the pressure. This displacement change will be transmitted to the second support plate 6 connected to the bottom, driving the second support plate 6 to move. During the forced movement of the second support plate 6, the spring 5 at the bottom will be further driven. Since the spring 5 has good elastic deformation characteristics, it will start to contract under the action of force. Through the contraction process of the spring 5, the impact force applied by the sole is effectively absorbed and buffered, thereby achieving a significant shock-absorbing effect, making the measurement of the rebound performance of sports shoes during the test more accurate and reliable, and thus improving the accuracy of the entire test. It provides a strong guarantee for accurately evaluating the rebound characteristics and quality level of sports shoes, and helps researchers, manufacturers and other relevant parties to deeply understand the performance of sports shoes in actual use scenarios, so as to carry out subsequent work such as product optimization and quality control.

[0039] Working principle: when using the sports shoes rebound tester, first pull the wrench 20, the wrench 20 drives the eccentric wheel 18 to rotate, the eccentric wheel 18 rotates on the side wall of the connecting block 17, then the eccentric wheel 18 rotates to drive the outer wall of the clamping plate 19 to make it resist against the outer wall of the scale column 3, and the connecting block 17 slides in the connecting block 17. Then pull the collar 16 to move on the outer wall of the scale column 3, and the outer wall of the scale column 3 is provided with scales to facilitate manual height adjustment, achieving the effect of convenient height adjustment. Then when clamping the shoes, directly rotate the handle 8, which drives the second gear 14 to rotate, the rotation of the second gear 14 drives the first gear 10 engaged with it to rotate, the rotation of the first gear 10 drives the first sliding column 11 in the inside of the first gear 10 to slide, and then the movement of the first sliding column 11 drives the first moving plate 13 at the bottom to move. In addition, the first moving plate 13 slides in the third connecting column 12 to support the first moving plate 13. The movement of the first moving plate 13 drives the clamping plate 15 at the bottom to rotate, and then the clamping plate 15 clamps the shoe edge after rotating, achieving the effect of supporting the shoe edge. Then when carrying out the rebound test, first press the sole part on the inner wall of the shell 1, then the shell 1 drives the second support plate 6 at the bottom to move, then the second support plate 6 drives the spring 5 at the bottom to contract, achieving the effect of shock absorption and improving the accuracy of the test.
