Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and more specifically, it relates to a zipper head anti-single tooth displacement testing device. Background Technology

[0002] Currently, when testing the anti-displacement performance of a single zipper tooth, there is a lack of dedicated fixing structures; the zipper tape is often directly clamped using the conventional fixtures of a tensile testing machine. This method is prone to two major problems: first, the fixtures tend to fix both the zipper tape and the zipper tooth simultaneously, making it impossible to apply force to a single tooth individually, resulting in dispersed test force and inaccurate testing of the single tooth's resilience; second, the clamping force is difficult to control. Too loose a clamp will cause the zipper tape to slip, while too tight a clamp will damage the zipper tape or the single tooth, causing deviations in test results and failing to meet the accurate requirements for testing the performance of a single zipper tooth, resulting in poor overall performance. Therefore, this utility model proposes a zipper head anti-displacement testing device. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a zipper head anti-single tooth displacement testing device, which is highly specialized and easy to operate.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is as follows: The utility model relates to a zipper head anti-single tooth displacement testing device, which includes a tensile testing machine, an upper clamp and a lower clamp, a single tooth fixing clamp on the upper clamp and a zipper tape fixing clamp on the lower clamp.

[0005] The present invention is further configured such that: the single tooth fixing clamp includes an upper clamp body, the side of the upper clamp body is provided with a groove with the opening facing outward and extending horizontally inward, the two ends of the groove are not connected to the outside, a first clamping tooth and a second clamping tooth extending out of the groove are slidably connected in the groove, an elastic element is provided between the second clamping tooth and the first clamping tooth, and an adjusting screw with its end abutting against the first clamping tooth or the second clamping tooth is threadedly connected to the end face of the upper clamp body.

[0006] The present invention is further configured such that: the end of the first clamping tooth facing the second clamping tooth and the end of the second clamping tooth facing the first clamping tooth are respectively provided with positioning grooves for the elastic element to be partially embedded.

[0007] The present invention is further configured such that the elastic element is a compression spring.

[0008] The present invention is further configured such that the adjusting screw is a hand-tightening adjusting screw.

[0009] The present invention is further configured such that: the zipper tape fixing clip includes a lower clamp body, the top of the lower clamp body is provided with an upwardly extending movable clamp piece and a fixed clamp piece, the fixed clamp piece is connected to the lower clamp body, and the movable clamp piece moves toward or away from the fixed clamp piece.

[0010] The present invention is further configured such that: an adjusting screw is threadedly connected to the fixed clamping piece, one end of the adjusting screw is rotatably connected to the movable clamping piece, and the other end is provided with a handle for controlling the rotation.

[0011] In summary, this utility model has the following beneficial effects: 1. The single-tooth fixing clamp allows only the movement of a single tooth, while permitting the movement of the zipper tape. It can apply force to a single tooth individually, avoiding force dispersion or damage, and accurately measuring the force value against displacement or tooth dislodgement of a single tooth.

[0012] 2.

[0016] Example 1 See Figures 1 to 4 As shown in the figure, the zipper head anti-single tooth displacement testing device involved in this embodiment includes a tensile testing machine 1, an upper clamp 2 and a lower clamp 3 on the tensile testing machine 1, a single tooth fixing clamp 4 on the upper clamp 2, and a zipper tape fixing clamp 5 on the lower clamp 3.

[0017] Furthermore, the single-tooth fixing clip 4 includes an upper clamp body 401. The side of the upper clamp body 401 is provided with a sliding groove 402 that extends outward and horizontally inward. The two ends of the sliding groove 402 are not connected to the outside. A first clamping tooth 403 and a second clamping tooth 404 extending out of the groove are slidably connected in the sliding groove 402. An elastic element 405 is provided between the second clamping tooth 404 and the first clamping tooth 403. The elastic element 405 is a compression spring. An adjusting screw 406 with its end abutting against the first clamping tooth or the second clamping tooth is threadedly connected to the end face of the upper clamp body 401. The adjusting screw 406 is a hand-tightening adjusting screw.

[0018] Furthermore, the zipper tape fixing clip 5 includes a lower clamp body 501. The top of the lower clamp body 501 is provided with an upwardly extending movable clamp piece 502 and a fixed clamp piece 503. The fixed clamp piece 503 is connected to the lower clamp body 501. The movable clamp piece 502 moves towards or away from the fixed clamp piece 503. An adjusting screw 504 is threadedly connected to the fixed clamp piece 503. One end of the adjusting screw 504 is rotatably connected to the movable clamp piece 502, and the other end is provided with a handle 505 for controlling rotation.

[0019] In this implementation scheme, the single-tooth fixing clamp is first installed on the upper clamp of the tensile testing machine, and the zipper tape fixing clamp is installed on the lower clamp; then, one end of the zipper tape is placed between the two teeth of the single-tooth fixing clamp, and the adjusting screw is used to restrict the movement of the target single tooth and allow the zipper tape to move, while the other end is clamped with the zipper tape fixing clamp; finally, the tensile testing machine parameters are set and started, and the force value when the single tooth shifts or dislodes is detected after the equipment applies force.
