[0002] An automotive seatbelt tensile tester is a device specifically designed to test and evaluate the performance of automotive seatbelts. Its primary function is to measure the strength and durability of seatbelts under tension, thereby ensuring their reliability and safety during actual use. This device typically consists of a tensile testing machine, a fixture, and a data acquisition system. The tensile testing machine applies a specified tensile force and accurately measures the belt's deformation and breaking strength under varying loads. The fixture secures the belt at both ends, ensuring stability and consistency during testing. The data acquisition system records various parameters in real time during testing, providing a basis for subsequent analysis.

[0003] When using a car seat belt tension test device, most of them clamp and fix the two ends of the seat belt to enable the seat belt to undergo tension testing. However, some existing clamps are manually operated by workers when in use, which causes the seat belt to loosen during the test, resulting in deviations in the test results. Therefore, there is a need to solve this problem. Utility Model Content

[0024] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: the first clamp 104 and the second clamp 105 are respectively installed on the top of the base 1, and the clamps 409 are respectively installed inside the first clamp 104 and the second clamp 105, and the clamps 409 are connected to the clamps through the tension spring 407, so that when the two ends of the safety belt are placed inside the first clamp 104 and the second clamp 105, the safety belt can be simply clamped and fixed by the clamps 409. When the fixation is completed, the motor 2 can be started, and the first screw rod 201 is installed on the output shaft of the motor 2. Therefore, when the motor 2 is started, the first screw rod 201 will rotate synchronously. An adjustment plate 3 is sleeved on the surface of the first screw rod 201, and the adjustment plate 3 slides inside the gantry 101. Therefore, under the constraint of the gantry 101, when the first screw rod 201 rotates, the adjustment plate 3 can be driven to move upward. A rack 303 is installed at the bottom of the adjustment plate 3, and the rack 303 cooperates with the gear 401 on one side of the fixture. As the adjustment plate 3 continues to move upward, the rack 303 can make the gear 401 rotate. A worm 4 is installed on one side of the gear 401, and the worm 4 is in contact with the second screw rod. The worm gear 402 on the surface of 403 cooperates, so that when the gear 401 rotates, the second screw rod 403 will rotate synchronously. A push plate 404 is provided on the surface of the second screw rod 403, so that when the second screw rod 403 rotates, the push plate 404 will move forward, and as the push plate 404 moves, it will squeeze the splint 409, so that the splint 409 can be more firmly connected to the safety belt. A fixed cone 405 is installed on one side of the push plate 404. When the push plate 404 and the splint 409 are in close contact, the fixed cone 405 will protrude from one side of the splint 409 to achieve direct contact with the safety belt. For the purpose of contact, the seat belt can be further fixed by setting the fixed cone 405, and a pressure sensor 304 is installed on the top of the adjustment plate 3. When the seat belt is fixed, the pressure sensor 304 will contact the second clamp 105. Because the second clamp 105 is sliding, when the pressure sensor 304 contacts the second clamp 105, it will drive the second clamp 105 to move upward. When the second clamp 105 moves upward, the test starts, and as the second clamp 105 continues to move upward, it will apply pressure to the pressure sensor 304, thereby achieving the purpose of detecting the pulling of the seat belt.
