DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-Figure 5 The shown device is a seat belt destructive force testing device, including a test bench 1, an outer wall of the test bench 1 is provided with a movable hole 5, a motor 2 is fixedly installed at the bottom of the outer wall of the test bench 1, the output end of the motor 2 is fixedly connected to a first threaded rod 7, and the first threaded rod 7 is rotatably connected to the bottom of the outer wall of the test bench 1 through a mounting plate, the outer wall of the first threaded rod 7 is screwed with an adapter seat 8, the top of the adapter seat 8 is fixedly connected to a movable seat 6, and the movable seat 6 is slidably connected to the inside of the movable hole 5, and a top pressure component is provided on the top of the movable seat 6. A pair of fixed components 3 that are far apart are also provided on the top of the outer wall of the test bench 1, and the two ends of the seat belt are fixed by the fixed component 3. The motor 2 drives the first threaded rod 7 to rotate, thereby driving the adapter seat 8 and the movable seat 6 to move synchronously, and correspondingly drives the top pressure component to move along the movable hole 5, thereby being able to perform a tensile test on the entire section of the seat belt.

[0021] The top pressure component includes a reinforcement block 18 fixedly connected to the top of the movable seat 6, and a fixing plate 21 is also fixedly connected to one side of the top of the outer wall of the movable seat 6. The fixing plate 21 and the reinforcement block 18 are both inserted and rotatably connected to the same screw sleeve 20. The end of the screw sleeve 20 is fixedly connected to an adjusting wheel 22, and the interior of the screw sleeve 20 is inserted and screwed with a second threaded rod 19. The end of the second threaded rod 19 is fixedly connected to a fixing head 25. One side of the outer wall of the fixing head 25 is fixedly connected to a deformable top plate 23. The deformed top plate 23 is set to an arc shape, and a plurality of rotatable rollers 24 are fixedly installed on one side of the outer wall of the deformed top plate 23. The screw sleeve 20 is rotated by rotating the adjusting wheel 22. At this time, the user presses the deformed top plate 23 to drive the adjusting wheel 22 out of the second threaded rod 19 inside, thereby adjusting the outward extension distance of the deformed top plate 23, and then forming top pressure on the safety belt to test its tensile strength. The setting of the roller 24 makes the deformed top plate 23 move more smoothly along the safety belt.

[0022] The outer wall of the fixed head 25 is fixedly connected to an adjusting arm 4 on both sides. The adjusting arm 4 consists of two rotating shafts and two connecting arms. The end of the adjusting arm 4 is fixedly connected to a magnetic plate 26. A plugging plate 27 is inserted through one side of the outer wall of the magnetic plate 26 and is slidably connected. An electromagnet 28 is fixedly connected to the bottom of one side of the outer wall of the plugging plate 27, and the electromagnet 28 is magnetically adapted to the magnetic plate 26. The plugging plate 27 is pre-pushed away to form a distance between it and the electromagnet 28. After the safety belt passes through the distance between the electromagnet 28 and the magnetic plate 26, the two are pulled in so that the electromagnet 28 contacts the magnetic plate 26. Then, the electromagnet 28 is energized to form a magnetic force to fix the safety belt. The position and angle of the plugging plate 27 can be adjusted by the adjusting arm 4, and then it is matched with the outward extension length of the deformed top plate 23, so as to facilitate the clamping and fixing of the safety belt. After the safety belt breaks, the magnetic force of the electromagnet 28 can ensure that the broken safety belt will not collapse to the surrounding area, thereby ensuring the safety of the entire test environment.

[0023] The fixing assembly 3 includes a winding shaft 9 fixedly connected to the top of the outer wall of the test bench 1, a cover plate 10 is fixedly connected to the top of the winding shaft 9, a second clamping plate 16 is fixedly connected to the bottom of the outer wall of the cover plate 10, and the second clamping plate 16 is set as an elastic structure. The outer wall of the cover plate 10 is also provided with a first clamping plate 14, and the first clamping plate 14 is fixedly connected to the outer wall side of the second clamping plate 16. A weakening band 17 is provided at one end of the outer wall of the second clamping plate 16. A mounting groove is opened at the top of the outer wall of the cover plate 10, and the inner part of the mounting groove is fixedly connected to the limit plate 12. The outer wall of the limit plate 12 An adjusting column 11 is inserted and rotatably connected, one end of the adjusting column 11 is provided with a thread, and the end of the adjusting column 11 is screwed with a moving block 13, and the moving block 13 is fixedly connected to the top of the outer wall of the first clamping plate 14. The second clamping plate 16 is moved to deform and open along the weakened band 17. The end of the safety belt is pressed against the winding shaft 9 and then released to clamp and fix the end of the safety belt. The safety belt is then wound along the winding shaft 9, and the adjusting column 11 is twisted to adjust the position of the moving block 13 so that the mortgage block 15 forms a mortgage on the outer wall of the safety belt, thereby completing the fixation of the safety belt.

[0024] Working principle:

[0025] By setting up the top pressure component and the fixing component, the entire section of the seat belt can be tensile tested. In addition to measuring the tensile strength of the seat belt, the strength and weakness of the entire section of the seat belt can also be determined. The test data obtained is more accurate and comprehensive.

[0026] By setting up structures such as the electromagnet 28 and the magnetic plate 26, the two ends of the safety belt are clamped in advance. During the movement of the deformed top plate 23, the electromagnet 28 and the second clamping plate 16 move synchronously along the safety belt. After the safety belt breaks, the magnetic force of the electromagnet 28 can prevent the broken safety belt from running out of control and hitting the surroundings, thereby improving the safety level of the test environment.
