It should be noted here that when the meshing resistance of the active gear 16 and the two sets of driven gears 17 is greater than the sliding friction force between the limit member 21 and the positioning groove of the power member 18 and the elastic force of the spring 22, the limit member 21 slides out of the positioning groove of the power member 18 to enable the power member 18 and the transmission member 19 to rotate relative to each other, preventing the meshing force between the driven gear 17 and the active gear 16 from being too large to cause damage to the drive motor 15. At the same time, it should be noted here that the device can perform two sets of tests on the seat belt, namely, a tension test in a stable state and a tension test under impact.

[0030] like Figures 1 to 4 As shown, as a preferred solution, a limiting member 9 is rotatably provided on the conductive member 10, a damping member 24 is provided on the limiting member 9, a positioning member 25 is slidably provided on the damping member 24, and the positioning member 25 is plugged and connected with the positioning hole of the hanging member 6; the positioning member 25 is positioned and slidably installed on the limiting member 9 by the damping member 24, the positioning member 25 is matched with the positioning hole of the hanging member 6 to lock the connection position of the limiting member 9 and the conductive member 10, the safety belt hung at the conductive member 10 is limited by the limiting member 9 to prevent slipping and improve safety, and the positioning member 25 is plugged and connected with the positioning hole of the hanging member 6 to facilitate disassembly and assembly.

[0031] like Figures 1 to 4 As shown, as a preferred solution, a follower 26 is provided on the limit member 9, and the follower 26 is located inside the limit hole of the conductive member 10; the limit member 9 and the conductive member 10 are connected to the sliding interval for limiting through the follower 26, thereby improving the convenience of device operation.

[0032] like Figures 1 to 4 As shown, as a preferred solution, two sets of protective members 27 are symmetrically arranged on the operating table 3, and the screw 13 is located inside the cavity of the protective member 27; the protective member 27 isolates and protects the screw 13 from the transmission of the moving member 7, thereby increasing work safety.

[0033] like Figures 1 to 5 As shown, as a preferred solution, its working process is as follows:

[0034] First, the safety belt is hung on the connecting member 4 on the tension test assembly 2 through the hook 5. Since the hook 5 can rotate, the difficulty of hanging the safety belt is greatly reduced. Then, the safety belt is guided to the appropriate position through the conductive member 10. The damping member 24 and the positioning member 25 on the limit member 9 work together to ensure that the safety belt is firmly hung and can be quickly inserted and removed to prevent it from slipping during the test.

[0035] Adjustment stage: Start the driving assembly, the driving motor 15 drives the driving gear 16 to rotate through the protection assembly, the driving gear 16 is meshed with the two sets of driven gears 17, driving the lead screw 13 to rotate, the lead screw 13 is threadedly connected with the moving part 7, so as to adjust the position of the moving part 7 and the hanging part 6. In this process, the auxiliary part 14 enhances the rotation stability of the lead screw 13 to ensure smooth and accurate movement.

[0036] Testing phase: When the driving motor 15 drives the lead screw 13 to rotate through the transmission mechanism, the moving part 7 moves accordingly, indirectly adjusting the distance between the hanging part 6 and the hook 5, thereby applying different pulling forces to the safety belt for testing. The power part 18, transmission part 19, limit part 21 and spring 22 in the protection component together constitute an overload protection mechanism. When the pulling force exceeds the set threshold, the limit part 21 will automatically slide out under the action of the elastic force of the spring 22 and the sliding friction force of the positioning groove, avoiding damage to the driving motor 15.

[0037] Steady state test and impact test: The device can perform two modes of testing. One is a tension test in a stable state, which is achieved by finely adjusting the position of the moving part 7; the other is an instantaneous tension test simulating an impact, which uses the drive motor 15 to quickly drive the seat belt to measure the instantaneous force change.

[0038] The utility model provides an intelligent safety belt tension testing tool, and its installation method, connection method or setting method are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
