Description

Technical Field

[0001] The utility model relates to the technical field of safety belt tension detection, in particular to a safety belt tension detector. Background Art

[0002] Seat belts are important devices used to protect the safety of personnel on equipment or vehicles. They are mainly used in high-altitude operations to prevent personnel from being injured due to accidental falls or collisions. At the same time, seat belts also play a vital role in cars and are one of the most important performance features of cars and other means of transportation. As an important device for personal safety protection, seat belts must undergo strict tension testing before being put into use.

[0003] When using existing tension detection equipment, the two ends of the seat belt are usually fixed respectively, and tension is continuously applied to one end, and the tension value is detected by the sensor on the equipment. However, when the seat belt is actually used, it is often not a straight line. Usually, people's bodies bend into different inclination angles, which makes the data detected by the existing detection technology unable to match the actual situation. In addition, the device used to pull the seat belt is usually a hook, which can easily cause the seat belt to detach during the detection process, posing a safety hazard. Utility Model Content

The bottom, the front side of the fixed table 4 is rotatably installed with a turntable 11, the surface of the turntable 11 is fixedly installed with an adjustment frame 12, the front side of the adjustment frame 12 is provided with an adjustment slot 13, the adjustment slot 13 is sleeved on the surface of the adjustment shaft 8, the surface of the turntable 11 is fixedly installed with meshing teeth 14, the meshing teeth 14 and the adjustment frame 12 are staggered, the front side of the fixed table 4 is rotatably installed with a gear 15, the gear 15 and the meshing teeth 14 are meshed and connected, the top of the workbench 1 is provided with a first limiting slot 16, the interior of the first limiting slot 16 is slidably installed with a first limiting block 17, the top of the first limiting block 17 is fixedly connected to the bottom of the movable table 5 Then, a second limiting groove 18 is provided on the right side of the inner wall of the movable platform 5, and a second limiting block 19 is slidably installed inside the second limiting groove 18. The left side of the second limiting block 19 is fixedly connected to the right side of the adjusting platform 6. A motor 22 is fixedly installed inside the fixed platform 4, and the output end of the motor 22 is fixedly connected to the rear side of the gear 15. By setting an adjustment mechanism, clamping devices are installed inside the fixed platform 4 and the adjusting platform 6. The clamping devices are prior art and will not be described here. The two ends of the safety belt are respectively fixed in the two clamping devices. When the safety belt needs to be subjected to tension tests at different angles, the motor 22 is started. The gear 15 is driven to rotate, and the meshing connection between the gear 15 and the meshing teeth 14 causes the meshing teeth 14 to drive the turntable 11 and the adjustment frame 12 to rotate, and the inner wall of the adjustment groove 13 causes compression on the adjustment shaft 8. The movable platform 5 moves to the left and the adjustment platform 6 moves upward, so that the safety belt is tilted. Since the center of the turntable 11 coincides with the clamped end of the safety belt inside the fixed platform 4, the safety belt maintains the initial tension during the tilting process, and there is no need to adjust the fixed length of the safety belt additionally, thereby solving the problem that the prior art only performs a linear tension test on the safety belt, which is not practical.

[0034] Reference Figure 1-4The stabilizing mechanism comprises a connecting rod 9 and an adapting shaft 10. The connecting rod 9 is fixedly mounted on the telescopic rod of the hydraulic rod 3. The adapting shaft 10 is rotatably mounted on the bottom of the connecting rod 9. A first clamping plate 20 is fixedly mounted on the bottom of the adapting shaft 10. A second clamping plate 21 is bolted to the bottom of the first clamping plate 20. By setting the stabilizing mechanism and starting the hydraulic cylinder, the connecting rod 9 drives the adapting shaft 10 and the first clamping plate 20 to move downward until the first clamping plate 20 contacts the top of the safety belt. Then, the second clamping plate 21 is connected by bolts so that the first clamping plate 20 and the second clamping plate 21 clamp and fix the safety belt. Moreover, by rotating the adapting shaft 10, the first clamping plate 20 and the second clamping plate 21 can adapt to the inclination angle of the safety belt to prevent slipping when the safety belt is pulled upward for tension detection, thereby avoiding the problem of unhooking that is easy to occur during the detection process in the prior art.

[0035] Specifically, the working process or working principle of the seat belt tension tester is as follows: when in use, the two ends of the seat belt are fixed in two clamping devices respectively. When the seat belt needs to be tested for tension at different angles, the motor 22 is started to drive the gear 15 to rotate. The meshing connection between the gear 15 and the meshing teeth 14 causes the meshing teeth 14 to drive the turntable 11 and the adjustment frame 12 to rotate. The inner wall of the adjustment groove 13 squeezes the adjustment shaft 8. The movable platform 5 moves to the left while the adjustment platform 6 moves upward to tilt the seat belt. Since the center of the turntable 11 coincides with the clamped end of the seat belt inside the fixed platform 4, the seat belt is tilted. The entire belt maintains its initial tightness during the tilting process, and there is no need to additionally adjust the fixed length of the seat belt. The hydraulic cylinder is started to drive the connecting rod 9 to drive the adaptation shaft 10 and the first clamping plate 20 to move downward until the first clamping plate 20 contacts the top of the seat belt. The second clamping plate 21 is then connected by bolts to clamp and fix the seat belt with the first clamping plate 20 and the second clamping plate 21. The first clamping plate 20 and the second clamping plate 21 can adapt to the tilt angle of the seat belt by rotating the adaptation shaft 10 to prevent slipping when the seat belt is pulled upward for tension testing.

[0036] It should be noted that the hydraulic rod 3 and the motor 22 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
