Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to a strength testing device for bulletproof vests. Background Art

[0002] Bulletproof vests, also known as bulletproof vests, bulletproof vests, bulletproof vests, bulletproof clothing, individual body protection equipment, etc., are used to protect the human body from damage caused by bullets or shrapnel. Bulletproof vests are mainly composed of two parts: a cover and a bulletproof layer. The cover is usually made of chemical fiber fabrics. The bulletproof layer is made of metal (special steel, aluminum alloy, titanium alloy), ceramic sheets (corundum, boron carbide, silicon carbide, aluminum oxide), fiberglass, nylon (PA), Kevlar (KEVLAR), ultra-high molecular weight polyethylene fiber (DOYENTRONTEXFiber), liquid protective materials, polyimide fiber (PI) and other materials to form a single or composite protective structure.

[0003] The Chinese utility model patent with patent number CN216847202U discloses a strength test device for bulletproof vests. When in use, the bulletproof vest is placed on the shell, the push rod is pressed to push the matching rod into the protective cover, the matching rod slides downward on the inner wall of the protective cover, and then the sliding rod is pushed downward, and the sliding rod pushes the positioning block to disengage from the pushing rod to unlock, and then the pushing rod is pushed into the shell to rotate the rotating rod on the clamp, the top of the rotating rod slides on the top inner wall of the shell, and the top of the rotating rod presses down the clamp to clamp the bulletproof vest, the push rod is released on the pushing rod, and then the matching rod and the sliding rod are released, the sliding rod releases the positioning block, and the positioning spring rebounds to perform the test. After resetting, the positioning block will be inserted into the positioning groove on the push rod, which can block the movement of the push rod and realize the positioning of the push rod. Then the push rod can continuously push the rotating rod. The clamp on the right adopts the same operation method. Since the two clamps fall asynchronously, the bulletproof vest with irregular surface can be stably clamped. The hydraulic device is started, and the hydraulic device presses the bulletproof vest. The pressure on the bulletproof vest is detected by the pressure sensor. When the bulletproof vest is penetrated, the current value of the pressure sensor is recorded, and the strength of the bulletproof vest is tested. To release the clamp, you only need to press the push rod to unlock the push rod first, and then the clamp can release the bulletproof vest through the rebound of the reset spring.

[0004] When actually testing the bulletproof vest, the bulletproof vest will have different protective effects due to testing at different angles. Therefore, it is usually necessary to perform strength tests on the bulletproof vest at different angles. However, when the device completes clamping and testing the bulletproof vest, it can often only perform strength tests on the bulletproof vest in a direction perpendicular to the hydraulic device, resulting in incomplete test data.
