[0002] The tensile strength test of the car seat belt webbing is a mandatory requirement of the state. The commonly used strength test method is to cut the seat belt webbing of appropriate length, fix the two ends of the seat belt webbing on the testing machine, and then conduct a tensile test. However, the choice of clamp has a great influence on the tensile strength test of the seat belt webbing. Most of the existing tensile tests on the seat belt are to clamp and fix the two ends of the seat belt, and then pull the clamp for testing. However, the clamping fixation is not only prone to the situation that the seat belt and the clamp slip and fall off, which easily leads to test failure, but also the seat belt cannot be twisted during the pulling process, and the testing method is relatively single.

[0003] To this end, the utility model provides a vehicle safety belt strength detection fixture. Utility Model Content

The utility model can roll up and pull the two ends of the seat belt. Compared with clamping and pulling, rolling up and pulling is more anti-slip and the force applied can be greater, thereby ensuring the detection effect; the seat belt can also be twisted to detect the anti-torsion effect of the seat belt and expand the detection range.

[0023] Specifically, when it is necessary to twist the seat belt 13 for detection, the seat belt 13 can be clamped and fixed by the clamping frame 4 and the clamping plate 5, and then the third motor 11 is started, so that the third motor 11 drives the first motor 9 to rotate through the connecting rod 12, thereby driving the upper clamp assembly 2 to rotate. At this time, the lower clamp assembly 3 remains stationary, which can drive the seat belt 13 to twist, so that the twisting of the seat belt 13 can be detected.

[0024] The output end of the first motor 9 is fixedly connected to the clamping frame 4 in the upper clamp assembly 2 , the output end of the second motor 10 is fixedly connected to the clamping frame 4 in the lower clamp assembly 3 , and the second motor 10 is fixedly connected to the support frame 1 .

[0025] Specifically, when it is necessary to perform a pulling test on the seat belt 13, the seat belt 13 is clamped and fixed between the clamping frame 4 and the clamping plate 5, and then the first motor 9 and the second motor 10 are started to drive the upper clamp assembly 2 and the lower clamp assembly 3 to rotate, thereby rolling up the two ends of the seat belt 13 until the seat belt 13 is straightened. At this time, the upper clamp assembly 2 and the lower clamp assembly 3 continue to be rolled up to perform a pulling test on the seat belt 13.

[0027] Specifically, when the safety belt 13 needs to be clamped and fixed, the safety belt 13 only needs to be placed between the clamping frame 4 and the clamping plate 5, and then the threaded rod 7 is rotated so that the threaded rod 7 pushes the slider 8 to move, thereby pushing the clamping plate 5 close to the clamping frame 4, and the safety belt 13 can be clamped between the clamping frame 4 and the clamping plate 5. At this time, the first anti-slip pattern 14 and the second anti-slip pattern 15 can play a certain anti-slip effect to ensure that the safety belt 13 will not fall off.
