Description

Technical Field

[0002] Sports shoes are designed and manufactured according to the characteristics of people participating in sports or traveling. The soles of sports shoes are different from ordinary leather shoes and rubber shoes. Generally, they are soft and elastic, which can play a certain buffering role, enhance elasticity during exercise, and some can also prevent ankle injuries. Therefore, when doing sports, people mostly wear sports shoes, especially for high-intensity physical activities such as basketball and running. Among them, EVA has the characteristics of light weight, softness, good elasticity, and excellent shock absorption performance, and the cost is relatively low. It is often used as the midsole material of sports shoes, which can provide a comfortable foot feeling and good buffering effect for the wearer.

Through the design of the moving component, the present invention can conveniently adjust the distance between the clamping components according to the size of the shoes, thereby improving the applicability of the device.

However, when detecting the sole made of EVA material, the detection is relatively single, and the performance of the EVA sole cannot be detected more comprehensively.

[0016] The present invention adopts the above technical solution to bring the following beneficial effects:

[0017] 1. A device for detecting the curvature of the sole of a sports shoe can flexibly adjust the inclination angle of the swing arm by providing a first adjusting screw and an adjusting block, thereby accurately adjusting the swing angle of the first swing plate. This design can better simulate the bending degree of the sole when a person walks, and meet the detection requirements of different sole curvatures. The electric push rod, the gear rod and the baffle cooperate with each other to drive the swing arm to swing back and forth, so that the first swing plate also swings back and forth, thereby detecting the number of bending times of the sole. By simulating the actual force and bending of the sole when a person walks, the device can more accurately evaluate the bending performance of the sole and provide more reliable data for the quality inspection of the sole.

[0018] 2. The device for detecting the bending degree of a sports shoe sole, through the meshing design of the first gear and the arc rack, drives the first friction roller to rotate when the first swing plate swings, and performs friction detection on the sole, simulating the friction state between the sole and the ground when a person walks. At the same time, when the moving frame moves, the straight rack drives the third gear to rotate, and then the second gear drives the second friction roller to perform friction detection on the middle position of the bottom of the sole. Multiple friction rollers perform friction on the sole from different positions, which can comprehensively evaluate the wear resistance of different parts of the sole, effectively improving the accuracy of wear resistance detection and providing a more comprehensive basis for the evaluation of the wear resistance performance of the sole.

[0019] 3. The device for detecting the bending degree of a sports shoe sole, through the structure composed of the first disc, the second disc and the connecting rod, drives the second swing plate to swing in the opposite direction when the first swing plate swings. This design can perform bending detection on different positions of the sole, namely the toe and heel parts, at the same time, evaluate the bending performance of the sole from multiple angles, and more comprehensively reflect the bending situation of the sole in actual use, ensuring the integrity of the detection results.

[0020] 4. The device for detecting the bending degree of a sports shoe sole, through the setting of the ultraviolet lamp and the heating plate, can simulate the external high-temperature environment and detect the influence of the high-temperature environment on the EVA sole. During the detection process, start the ultraviolet lamp and the heating plate to simulate the high-temperature situation that the sole may encounter in the actual use scenario, and observe the performance changes of the sole under high temperature, such as whether it is deformed or aged. This helps to evaluate the quality stability of the sole under different environmental conditions and provides an important reference for product research and development and quality control.

[0021] 5. The device for detecting the bending degree of a sports shoe sole, with the cooperation of components such as the second adjusting screw, the moving seat, the moving rod and the pressing frame on the base, can be adjusted and fixed according to the sizes of different soles. By rotating the second adjusting screw to drive the moving seat to move, the moving rod moves along the inclined groove, and then drives the pressing frame to move downward to firmly fix the sole sample on the middle plate. This design enhances the applicability of the device to different specifications of soles, ensures the stability of the sole during the detection process, and improves the reliability of the detection.

[0038] Working principle: Place the EVA sole sample to be detected on the middle plate 3, with the toe of the EVA sole on the first swing plate 4 and the heel of the EVA sole on the second swing plate 5. Rotate the second adjusting screw 14 to drive the moving seat 15 to move, thereby driving the moving rod 17 to move along the inclined slot 12. The moving rod 17 will drive the pressing frame 18 to move downward, thus fixing the EVA sole sample on the middle plate 3. Separate one end of the swing rod 65 from the first rotating shaft. By rotating the first adjusting screw 63, the first adjusting screw 63 drives the adjusting block 64 to move left and right, thereby adjusting the inclination angle of the swing rod 65. By adjusting the inclination angle of the swing rod 65, the inclination angle of the first swing plate 4 is adjusted. When the adjusting block 64 moves to the left, the inclination angle of the first swing plate 4 increases. When the adjusting block 64 moves to the right, the inclination angle of the first swing plate 4 decreases. After the adjustment of the adjusting block 64 is completed, the swing rod 65 is snapped onto the first rotating shaft to fix the swing rod 65. By starting the electric push rod 61 to drive the moving frame 62 to move to the right, when the shift lever 66 contacts the baffle 67, the electric push rod 61 drives the moving frame 62 to move to the left, and so on. Thus, the swing rod 65 is driven to swing by the adjusting block 64, and then the first swing plate 4 is driven by the first rotating shaft to bend the toe of the sole. At the same time, when the first swing plate 4 swings, the first gear 610 will move on the arc rack 611, thereby driving the first rotating rod 68 to rotate, and then driving the first friction roller 69 to rotate to friction the bottom of the sole, so as to simulate the state of human walking and detect the bending and wear resistance of the sole. At the same time, when the moving frame 62 moves, it will drive the straight rack 75 to move, thereby driving the second gear 73 to rotate through the third gear 74, and then driving the second friction roller 72 to friction the middle position of the bottom of the sole, so as to detect the wear resistance of different positions of the sole and improve the accuracy of detection.

An installation groove is formed in the top of the second swing plate 5, and a heating plate 812 is fixedly installed on the inner wall of the installation groove.

[0040] Working principle: When the first swing plate 4 swings, it will drive the first disc 82 to rotate, thereby driving the second disc 83 to rotate in the opposite direction through the connecting rod 84, and then driving the second swing plate 5 to swing in the opposite direction to further detect the bending of the shoe sole. At the same time, by starting the ultraviolet lamp 811 and the heating plate 812, it is used to simulate the influence on the shoe sole under the external high-temperature environment. At the same time, when the second swing plate 5 swings upward, it will drive the side rod 810 to move to the right under the action of the first sliding rod 86, thereby driving the moving frame 89 to move, and then driving the ultraviolet lamp 811 to move, so that the ultraviolet light can irradiate the heel part of the shoe comprehensively, and check the influence of the environment on the EVA shoe sole by simulating the external high-temperature environment.
