[0002] Zipper durability detection devices are generally used to evaluate the performance and durability of zipper products after repeated use and opening / closing operations. The design and function of these devices are aimed at simulating the operations in the real usage environment so that manufacturers and testing institutions can evaluate the quality and durability of zipper products.

[0003] The patent with the patent publication number CN205849443U relates to a zipper detection device, which includes a bracket, a feeding device arranged on the bracket, and a detection camera for detecting the zipper. The feeding device is provided with a guiding track for the zipper to pass through and a detection hole for facilitating the zipper detection. The detection hole penetrates through the feeding device and is communicated with the guiding track, and the lens of the detection camera is directly opposite to the detection hole. When using the zipper detection device provided by this patent to detect the zipper, the zipper moves along the guiding track of the feeding device to the detection hole, and the detection camera can directly detect each component such as the teeth, top stop, bottom stop, and pull head of the zipper through the detection hole. This zipper detection device uses a detection camera to replace manual detection, changes the zipper detection method in the prior art, can save manpower, improve the detection efficiency and accuracy of the zipper, and thus makes the zipper detection time-saving and labor-saving.

[0004] In the above patent, each component such as the teeth, top stop, bottom stop, and pull head of the zipper can be directly detected by the camera through the detection hole, which changes the zipper detection method in the prior art, can save manpower, improve the detection efficiency and accuracy of the zipper, and thus makes the zipper detection time-saving and labor-saving. However, the detection result is relatively single, and it is difficult to effectively detect the zipper at different opening / closing angles, which further affects the reliability of the detection result. Therefore, a durability detection device for manufacturing new energy vehicle seat zippers with an adjustment function is designed. Summary of the Invention

[0021] Four measuring devices 8 are provided. Adjustment grooves are formed on the surface of the mounting plate 7. The middle two measuring devices 8 are slidably mounted inside the adjustment grooves. Card slots are formed on the surface of the adjustment plate 9. The measuring devices 8 are in contact with the card slots. Positioning grooves are formed on the surface of the mounting plate 7. The detection ends of the measuring devices 8 are sleeved under the lifting plate 11. The detection ends of the two outer measuring devices 8 are fixedly connected to the side clamps 6 through metal wires. The measuring ends of the measuring devices 8 move up and down to record data. At the same time, the side clamps 6 move under the action of the metal wires to drive the measuring ends of the measuring devices 8 to move and record data, thereby realizing the durability detection of the zipper.

[0022] A first spring 15 is arranged between the limiting rod 10 and the adjustment plate 9. The metal mechanism is in contact with the fixed pulley 14. The upper part of the adjustment plate 9 is slidably connected to the receiving plate 13. The first spring 15 can drive the limiting rod 10 to reset.

[0023] During the operation of this embodiment: Fix the upper part of the zipper to the upper clamp 5, fix the slider of the zipper to the slider clamp 4, fix the side of the zipper to the side clamp 6, and fix the two lower ends of the zipper to the lower clamp 12. Then start the electric push rod 2. The output end of the electric push rod 2 moves up and down to drive the lifting frame 3 to move up and down. The lifting frame 3 moves up and down to drive the slider clamp 4 to move up and down. The slider clamp 4 moves up and down to drive the slider to move up and down and detect the zipper. During the up and down movement of the zipper slider, the opening and closing drive the lower clamp 12 to swing. During the swinging process of the lower clamp 12, it will drive the lifting plate 11 to move up and down, thereby causing the measuring ends of the measuring devices 8 to move up and down and record data.

After releasing the limit, move the adjustment plate 9 to drive the measuring device 8 to move. When it moves to the appropriate position, the limiting rod 10 resets under the action of the first spring 15 and contacts the card slot again. By adjusting the distance between the adjustment plates 9, the detection angle of the zipper is changed, thereby better simulating the different opening and closing angles of the zipper in actual use, more realistically evaluating the durability and reliability of the zipper under different use conditions, and preventing the position of the adjustment plate 9 from changing during the detection process due to accidental touch, thereby affecting the accuracy of the detection result. At the same time, it provides more data support for product design to optimize the structure, material selection or production process of the zipper to improve the overall quality and performance of the product.

[0024] Please refer to Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, a detection device is further included. The detection device is arranged on the surface of the equipment frame 1. The detection device includes a lifting rod 161 and a clamping block 162. The lifting rod 161 is slidably installed on the outer wall of the equipment frame 1, and the clamping block 162 is fixedly installed on the surface of the lifting rod 161. The detection device further includes an L-shaped plate 163, a connecting rod 164, an arc-shaped plate 165, a sliding plate 166 and a pressing block 167. The L-shaped plate 163 is slidably installed above the receiving plate 13. The connecting rod 164 is rotatably installed above the lifting rod 161. The arc-shaped plate 165 is slidably installed inside the first chute. The sliding plate 166 is slidably installed inside the lifting frame 3. The pressing block 167 is fixedly installed on one side of the upper fixture 5 close to the arc-shaped plate 165. The pressing block 167 moves up and down to contact the arc-shaped plate 165 and makes a lateral movement under its action, and is reset under the action of the second spring 169. Thus, while the vertical detection of the zipper is realized, the lateral detection is also carried out, further evaluating the functionality and durability of the zipper in different usage scenarios, and ensuring the stability and reliability of the zipper under various usage conditions.

[0025] The sliding plate 166 is fixedly connected to the upper fixture 5. One end of the connecting rod 164 away from the lifting rod 161 is rotatably connected to the arc-shaped plate 165. When the lifting rod 161 moves, it drives the arc-shaped plate 165 to move through the connecting rod 164 and enters the movement track of the pressing block 167.

[0026] A first telescopic spring rod 168 is fixedly installed above the receiving plate 13. The free end of the first telescopic spring rod 168 is fixedly connected to the lifting rod 161. The first telescopic spring rod 168 can drive the lifting rod 161 to reset. A second spring 169 is arranged between the sliding plate 166 and the inner wall of the lifting frame 3. The second spring 169 can drive the sliding plate 166 to reset.

[0027] A tension control device is further included. The tension control device includes a sliding block 171 and a driven wheel 172. A first chute is formed on the surface of the equipment frame 1. The sliding block 171 is slidably installed inside the first chute. The driven wheel 172 is rotatably installed on the surface of the sliding block 171. The tension control device further includes a cross bar 173 and a pressing rod 174. The cross bar 173 is fixedly installed on one side of the sliding block 171 close to the arc-shaped plate 165. The pressing rod 174 is fixedly installed on one side of the arc-shaped plate 165 close to the sliding block 171. The metal wire contacts the driven wheel 172. When the driven wheel 172 moves downward, the tension of the metal wire is reduced, avoiding excessive tension on the zipper due to the increased moving distance of the side fixture 6 during the lateral detection of the zipper, which may cause the zipper to break under excessive stress, maintaining the stability of the tension on the zipper during the detection process, and more accurately evaluating the durability and stability of the zipper.

[0028] A telescopic elastic rod 2 175 is fixedly installed at the bottom of the inner wall of the slide groove 1, and the free end of the telescopic elastic rod 2 175 is fixedly connected to the sliding block 171. The telescopic elastic rod 2 175 can drive the sliding block 171 to reset. The upper side of the squeezing rod 174 close to the cross bar 173 is set as an oblique surface, and the squeezing rod 174 squeezes the cross bar 173 through the oblique surface to move upward.

[0029] When the present embodiment is working, the L-shaped plate 163 is moved to be out of contact with the block 162 and the limit of the lifting rod 161 is released. After the limit is released, the lifting rod 161 moves upward under the action of the telescopic spring rod 168, and the lifting rod 161 moves upward to enter the motion trajectory of the adjustment plate 9. Then the adjustment plate 9 moves to contact and squeeze the lifting rod 161 to move upward. The lifting rod 161 moves upward to drive the connecting rod 164 to move. The movement of the connecting rod 164 drives the arc plate 165 to move in the direction close to the chain head clamp 4 and enter the motion trajectory of the extrusion block 167. At the same time, the chain head clamp 4 moves up and down to drive the extrusion block 167 to move up and down. The moving contact arc plate 165 moves laterally under its action, the extrusion block 167 moves laterally to drive the chain head clamp 4 to move laterally, the chain head clamp 4 moves laterally to drive the sliding plate 166 to move laterally inside the lifting frame 3, the sliding plate 166 moves to squeeze the second spring 169 and reset under its action, thereby realizing the lateral detection of the zipper while detecting it in the vertical direction, further evaluating the functionality and durability of the zipper in different usage scenarios, ensuring the stability and reliability of the zipper under various usage conditions, and after the lifting rod 161 moves upward, the L-shaped plate 163 is moved to contact the block 162 again and limit it, thereby improving the stability of the zipper during the detection process.

[0030] When the arc plate 165 moves toward the direction close to the chain head clamp 4, it drives the squeezing rod 174 to move. The squeezing rod 174 moves out of contact with the cross bar 173 and releases the limit on it. After the limit is released, the sliding block 171 moves downward under the action of the telescopic elastic rod 175. The sliding block 171 moves downward and drives the driven wheel 172 to move downward. The driven wheel 172 moves downward to reduce the tension on the metal wire, thereby avoiding excessive tension on the zipper due to the increase in the moving distance of the side clamp 6 when the zipper is horizontally inspected, causing the zipper to collapse under excessive stress, maintaining the stability of the tension on the zipper during the inspection process, and more accurately evaluating the durability and stability of the zipper. At the same time, when the arc plate 165 moves to reset in the direction away from the chain head clamp 4, the squeezing rod 174 moves to contact and squeeze the cross bar 173 to move upward, and the cross bar 173 moves upward and is limited again, thereby avoiding affecting subsequent zipper inspections and reducing subsequent maintenance costs.

[0031] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and permutations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
