[0024] Referring to Figures 1-6 A zip fastener tensile strength detection device, including table body 1, the upper surface of table body 1 is vertically rotatably installed with rotating rod 2, rotating rod 2 is fixedly sleeved with gear 3, the upper surface of table body 1 is slidably installed with two rack rods 4, which are all meshed with gear 3, as shown in Figure 5 The sliding part includes two pairs of sliding rods 9 fixedly installed at the bottom of the two rack rods 4, the upper surface of table body 1 is symmetrically provided with sliding grooves 10, the bottom ends of the two pairs of sliding rods 9 are slidably installed in the two sliding grooves 10 respectively, the top of rack rod 4 is fixedly installed with L-shaped mounting block 5 through connecting rod 16, the surface of mounting block 5 is vertically provided with vertical opening 6, threaded rod 7 is rotatably installed in vertical opening 6, and T-shaped clamping plate 8 is threadedly connected to threaded rod 7.

[0025] Referring to Figure 6 The surface of mounting block 5 is provided with an adjusting assembly for controlling the rotation of threaded rod 7, the adjusting assembly includes worm wheel 11 fixedly sleeved on threaded rod 7 and worm 12 meshed with worm wheel 11, L-shaped block is fixedly installed on the surface of mounting block 5, worm 12 is rotatably installed on the surface of L-shaped block, and one end of worm 12 penetrates through L-shaped block and is fixedly installed with adjusting wheel, the bottom of table body 1 is provided with a drive assembly for controlling the rotation of rotating rod 2, the drive assembly includes drive motor 13 fixedly installed on the lower surface of table body 1, the output shaft of drive motor 13 penetrates through table body 1 and is fixedly connected with rotating rod 2.

[0026] Before detecting the zipper to be detected, first, the operator places the zipper to be detected and in the fully engaged state horizontally, makes the engaged part of the zipper in the center, puts the two side edges of the zipper on the horizontal end surface of the two L-shaped mounting blocks 5 respectively, ensures that the engaged part of the zipper remains flat, and the positions of the two side edges correspond to the T-shaped clamping plates 8 on the two mounting blocks 5 respectively, and prepares for the subsequent pressing and clamping of the two side edges.

[0027] Then, the operator rotates the adjusting wheel on the surface of one of the mounting blocks 5, since the adjusting wheel is fixedly connected with the worm 12, the rotation of the adjusting wheel drives the worm 12 to rotate horizontally on the L-shaped block, since the worm 12 is engaged with the worm gear 11 fixedly sleeved on the threaded rod 7, the rotation of the worm 12 drives the worm gear 11 to rotate synchronously, and further drives the threaded rod 7 to rotate vertically in the vertical opening 6 on the surface of the mounting block 5, since the T-shaped clamping plate 8 is threadedly connected with the threaded rod 7, and the vertical opening 6 limits the T-shaped clamping plate 8, the rotation of the threaded rod 7 drives the T-shaped clamping plate 8 to move vertically downward along the vertical opening 6, until the lower surface of the T-shaped clamping plate 8 tightly presses the side edge of the zipper, and clamps the side edge of the zipper between the T-shaped clamping plate 8 and the horizontal end surface of the mounting block 5, and the above operation is repeated to rotate the adjusting wheel on the other mounting block 5, so that the corresponding T-shaped clamping plate 8 moves downward and presses and clamps the other side edge of the zipper, and the pressing and clamping of the two sides of the zipper in the engaged state are completed.

[0028] If it is necessary to adjust the horizontal position of the zipper to ensure that the engaged part is in the center horizontal state required for detection, the drive motor 13 fixedly installed on the lower surface of the table body 1 can be started, the output shaft of the drive motor 13 penetrates through the table body 1 and is fixedly connected with the rotating rod 2, the drive motor 13 drives the rotating rod 2 to rotate vertically on the upper surface of the table body 1, the gear 3 fixedly sleeved on the rotating rod 2 rotates synchronously with the rotating rod 2, since the two rack rods 4 are engaged with the gear 3, the rotation of the gear 3 drives the two rack rods 4 to slide reversely in the horizontal direction, at this time, the two pairs of slide rods 9 fixedly installed on the bottom of the rack rod 4 slide synchronously in the two symmetrical slide grooves 10 on the upper surface of the table body 1, and further drives the mounting block 5 fixedly connected with the connecting rod 16 on the top of the rack rod 4 to move reversely synchronously, until the engaged part of the zipper is adjusted to the appropriate horizontal position, and the drive motor 13 is turned off, and the positioning and clamping of the two sides of the zipper in the engaged state are completed, and the subsequent tensile strength detection is prepared.

[0029] Referring to Figure 4 , two fixed blocks corresponding to the positions of the two rack rods 4 are fixedly installed on the upper surface of the table body 1, the tension meters 14 are fixedly installed on the surface of the fixed blocks, the pull rings 15 are fixedly installed on one end of the rack rod 4 close to the tension meters 14, and the hooks of the two tension meters 14 are hung on the two pull rings 15 respectively.

[0030] Before starting the drive motor 13 to detect the tensile resistance, the operator needs to confirm the connection state of the upper surface of the table body 1. The upper surface of the table body 1 is fixedly installed with two fixed blocks, and the two fixed blocks are one-to-one corresponding to the positions of the two rack rods 4. Each fixed block is fixedly installed with a tension meter 14 on the surface, and the end of the rack rod 4 close to the tension meter 14 is fixedly installed with a pull ring 15. It is necessary to ensure that the two tension hooks of the two tension meters 14 are respectively hung on the two pull rings 15, and the tension hook is firmly connected with the pull ring 15 without loosening or falling off risk, so as to make good connection preparation for tensile test.

[0031] Start the drive motor 13 on the lower surface of the table body 1. The drive motor 13 drives the rotating rod 2 and the gear 3 to rotate, and then drives the two rack rods 4 to slide in the horizontal direction in the reverse direction. Since the rack rod 4 is clamped on both sides of the zipper through the installation block 5 and the T-shaped clamping plate 8, the rack rod 4 will exert a horizontal tension on the zipper when it slides in the reverse direction. At this time, the pull ring 15 at one end of the rack rod 4 will pull the tension hook of the tension meter 14 synchronously. After the tension meter 14 is subjected to the tension, it will display the current tension value in real time. The operator can observe the readings of the two tension meters 14 and record the real-time tension change of the zipper during the tension process until the zipper appears disengagement, tooth fracture and other failure conditions. At this time, the maximum value displayed by the tension meter 14 is the tensile strength value of the zipper, and the tensile strength detection is completed.

[0032] After the detection is completed, the drive motor 13 is turned off. After the rack rod 4 stops moving, the operator reversely rotates the adjusting wheels on the two installation blocks 5 to make the T-shaped clamping plate 8 move upward along the vertical port 6, loosen the pressure clamping on both sides of the zipper, take down the detected zipper, and then take down the tension hook of the tension meter 14 from the pull ring 15 of the rack rod 4 to complete the separation of the tension meter 14 and the pull ring 15, and make preparation for the next detection.

[0033] The surface of the clamping plate 8 and the installation block 5 is bonded with a rubber anti-skid layer, and the material of the anti-skid layer is rubber.

[0034] The rubber anti-skid layer bonded on the surface of the clamping plate 8 and the installation block 5 utilizes the characteristic of high friction coefficient of the rubber material itself to greatly increase the contact friction force between the clamping plate 8 and the side edge of the zipper and between the installation block 5 and the side edge of the zipper. During the detection process, when the rack rod 4 drives the installation block 5 to slide in the reverse direction to exert a horizontal tension on the zipper, the rubber anti-skid layer can effectively prevent the zipper from sliding or misplacing between the clamping plate 8 and the installation block 5, so as to ensure that the zipper is always in a stable clamping state and avoid interruption or data deviation caused by slipping during detection.

[0035] The rubber material has good elasticity and flexibility, and when the clamping plate 8 is pressed downward to clamp the side edge of the zipper, the rubber anti-skid layer can play a buffering role, avoiding the direct contact between the clamping plate 8 and the hard surface of the mounting block 5 to cause extrusion damage, especially for the zipper with a surface coating or fabric material, which can reduce scratches and indentation during clamping, thereby ensuring the integrity of the zipper sample after detection and reducing the risk of misjudgment of the zipper tensile performance due to clamping damage.

[0036] In the utility model, the transmission structure formed by the rotating rod 2, the gear 3 and the two rack rods 4, cooperating with the driving assembly at the bottom of the table body 1, can synchronously control the two rack rods 4 to slide reversely along the horizontal direction, and further drive the mounting block 5 at the top to move synchronously, without manually adjusting the positions of the two sides of the zipper in the meshing state, so that the two sides of the zipper can be quickly aligned, meanwhile, the adjusting assembly on the mounting block 5 cooperates with the threaded rod 7 and the T-shaped clamping plate 8, so that the clamping plate 8 can be quickly driven to move vertically, and the two sides of the zipper in the meshing state can be clamped and fixed, the whole positioning and fixing process is simple and easy to operate, and the synchronization is strong, and the problems of complicated positioning and long time of the traditional device are effectively solved.

[0037] In the utility model, unless otherwise clearly defined and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood in a broad sense.

[0038] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
