Description

Technical Field

[0001] This utility model is a shape retention force testing device for knee protection, belonging to the field of shape force testing devices. Background Technology

[0002] Occupational safety equipment (OSB) refers to essential protective gear for workers' personal safety and health during the production process. It plays a crucial role in reducing occupational hazards. Knee braces are items used to protect the knees, providing protection during exercise, warmth, and joint support. They are categorized into sports knee braces and general health knee braces, suitable for athletes, the elderly, and those with knee problems. Furthermore, during the production of occupational safety knee braces, force testing devices are used to check the shape retention of the braces.

[0003] Traditional knee brace force testing devices, when used to test knee braces, prevent the internal air from escaping easily because the knee brace is placed in an arched position. This affects the testing results. Furthermore, when the vent holes are placed downwards, impurities and dust in the air can easily fall onto the lifting structure, increasing workload and reducing the lifespan of the equipment. In addition, conventional testing devices apply pressure to the knee brace from above, with a fixed platform at the bottom, which limits the effectiveness of the testing and indirectly reduces work efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a shape retention force testing device for knee braces. This addresses the problems of traditional knee brace force testing devices, where the knee brace is placed in an arched position, making it difficult for internal air to escape during testing, thus affecting the testing results. Furthermore, when the ventilation holes are placed downwards, impurities and dust in the air easily fall onto the lifting structure, increasing workload and reducing the equipment's lifespan. Additionally, conventional testing devices apply pressure to the knee brace from above, with a fixed platform at the bottom, which limits the testing effectiveness and indirectly reduces work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a knee brace shape retention force testing device, comprising a base, a lifting structure, a support plate, a limiting sleeve, a first support rod, a second support rod, a top plate, a motor, a fixing plate, a third support rod, a lifting device, and a pressure plate. The top of the base is fixedly integrated with the lifting structure, the top of the lifting structure is connected to the support plate, and the bottom left and right ends of the support plate are fixedly integrated with the limiting sleeve. The upper and lower ends of the first support rod pass through the top plate and the support plate respectively, and the bottom of the first support rod is vertically fixed to the base. A motor is installed on the top of the top plate, and the lower end of the motor is connected to the fixing plate. The components are fixed together. The bottom of the fixed plate is vertically fixed to the third support rod. A lifting device is provided on the top of the top plate. The lower end of the lifting device is fixed to the pressure plate. The lifting structure includes a fixed seat, a base, a separate connecting rod, a lead screw, a fixed block, a screw rod, and a handwheel. The top of the fixed seat is fixed to the base. The front and rear ends of the inner side of the base are connected to the separate connecting rod. The inner side of the separate connecting rod is connected to the screw rod. The right end of the screw rod is movably fitted with the fixed block. The front end of the fixed block is connected to the screw rod. The right end of the fixed block is fixed to the handwheel. The bottom of the fixed seat is vertically fixed to the base. The top of the separate connecting rod is connected to the support plate.

[0006] Furthermore, the support plate includes a plate body, a vent hole, an air outlet hole, a barrier plate, and a convex plate. The top of the plate body has a vent hole, and the left and right ends of the plate body have air outlet holes. A barrier plate is provided above the air outlet hole. The middle of the bottom inner side of the plate body is fixed to the convex plate. The left and right ends of the bottom of the plate body are vertically fixed to the limiting sleeve. The left and right ends of the plate body are connected through the first support rod. The bottom of the plate body is connected to the lifting structure.

[0007] Furthermore, slots are provided at the center of both the left and right ends of the plate, and the slots are connected through the first support rod.

[0008] Furthermore, the convex plate is arc-shaped, and its surface is polished.

[0009] Furthermore, the detachable connecting rod includes a first connecting rod, a second connecting rod, a rotating shaft, and a support block. The outer right end of the first connecting rod is movably connected to the second connecting rod. The rear end of the rotating shaft passes through the inner front end of the first and second connecting rods and is located in the middle of the inner side of the support block. The outer sides of the first and second connecting rods are connected to the base, and the top of the support block is fixed to the plate.

[0010] Furthermore, there are two air vents, which are located at the front and rear ends of the plate.

[0011] Advantages: This utility model provides a shape retention force testing device for knee braces. By setting a lifting structure on the top of the base, the screw can lift the plate after the handwheel is turned, thereby improving the ability to test different knee braces. At the same time, the ventilation holes and air vents inside the plate facilitate the discharge of residual air inside the compressed knee brace, and also prevent residues and dust in the air from falling and accumulating on the lifting structure, reducing workload and increasing the service life of the equipment.

Next, place the knee pad to be processed on the top of the plate 31, and then start the motor 8 to work, so that the lifting device 11 drives the pressure plate 12 to lift and lower. Then the force of the knee pad can be tested. During the process of the pressure plate 12 pressing down, the compressed air at the bottom of the knee pad can enter the plate 31 through the vent 32, and then the air is discharged from the air outlet 33 opened at the left and right ends of the plate 31 by the convex plate 35, thereby avoiding affecting the service life of the lifting structure 2.

[0026] Second, before testing the knee brace, the staff can also rotate the handwheel 27 to make the lead screw 24 rotate in the base 22, which in turn makes the first connecting rod 231 and the second connecting rod 232 work together to achieve the effect of lifting and lowering the plate 31, thereby improving the limitations of the test.
