Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, specifically to a shoe sole flexural strength testing machine. Background Technology
[0002] The construction of shoe soles is very complex. They are generally made of natural rubber or synthetic rubber. Shoe soles generally have properties such as wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, flexural resistance, good elasticity, resistance to deformation, heat insulation, and easy absorption of moisture. The flexural resistance of shoe soles is a mandatory test item for all footwear performance testing and a key indicator for evaluating the durability of shoes.
[0003] Existing shoe sole flexural endurance testing machines can only test the flexural endurance of one side of the sole when bending it, which is quite limited. Furthermore, they can only test the flexural endurance of soles with a fixed thickness, and cannot test soles of various thicknesses, resulting in low applicability. In addition, they cannot fix the sole securely, which can easily cause the sole to slip off, affecting the flexural endurance test. Therefore, we propose a shoe sole flexural endurance testing machine. Utility Model Content
[0004] In view of the problems existing in the current shoe sole flexural endurance testing machine, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a shoe sole flexural endurance testing machine, which solves the problem that existing shoe sole flexural endurance testing machines can only test the flexural endurance of one side of the shoe sole when bending it, which has great limitations. Furthermore, they can only test the flexural endurance of shoe soles of a fixed thickness and cannot test shoe soles of various thicknesses, resulting in low applicability. At the same time, they cannot fix the shoe sole securely, which can easily cause the shoe sole to slip off, affecting the flexural endurance testing.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A shoe sole flexural endurance testing machine includes a base, a fixed frame, and a placement plate. Fixed frames are provided at both ends of the top surface of the base. Support blocks are slidably arranged inside multiple fixed frames. A fixed plate is fixedly installed on the top of each of the support blocks. A rotating shaft is rotatably arranged between opposite ends of two fixed plates on one side. Fixed rings are fixedly installed on the surfaces of the two rotating shafts. A placement plate is fixedly installed on the surfaces of the two fixed rings. A support plate is fixedly installed at one end of the base. A top plate is fixedly installed on the surface of one end of the support plate. A telescopic rod is fixedly installed at the bottom of the top plate. A limit frame is fixedly installed at the moving end of the telescopic rod.
[0008] Preferably, a bidirectional lead screw is rotatably provided between the top and bottom of the inner side of the limiting frame, and a sliding plate is threaded to both the top and bottom of the bidirectional lead screw, with a limiting post fixedly installed at one end of each of the two sliding plates.
[0009] Preferably, a limiting plate is fixedly installed on the top of each of the two placement plates, and an installation plate is fixedly installed on one side of each of the two limiting plates.
[0010] Preferably, both mounting plates are threadedly connected to adjusting columns, and both adjusting columns are rotatably provided with clamping plates at their bottoms.
[0011] Preferably, a motor is fixedly installed at the bottom of the limiting frame, and the output end of the motor is fixedly connected to the bottom of the bidirectional lead screw.
[0012] Preferably, both of the limiting posts are located between the two placement plates.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] This utility model features multiple fixed frames on the base surface, a placement plate on the top of two fixed frames on one side, a limiting frame at the bottom of the top plate, and a limiting post inside the limiting frame. This design not only facilitates clamping shoe soles of different sizes and thicknesses but also securely fixes the shoe soles to prevent them from slipping during testing. Furthermore, it allows for simultaneous testing of both sides of the shoe sole, improving testing efficiency and increasing the practicality of the device. Attached Figure Description
