The embodiments described below by reference to the drawings are exemplary, only for explaining the present application, and cannot be understood as limiting the present application.

[0025] Please refer to Figures 1-4This utility model discloses a zipper pull strength testing device, including a mounting frame 1, which is the mounting structure of the device and is used to install the overall structure. A first sliding groove 11 is provided on the inner side of the upper part of the mounting frame 1. A second sliding groove 2 and a third sliding groove 3 are respectively provided on both sides of the first sliding groove 11. The first sliding groove 11, the second sliding groove 2, and the third sliding groove 3 are all mounting structures. A sliding block 12 is slidably arranged inside the first sliding groove 11. The sliding block 12 is locked in the first sliding groove 11 and slides. An installation post 13 is provided on the top of the sliding block 12. The installation post 13 is used to install the zipper pull tab, that is, the pull tab can be inserted into the installation post 13. A sliding component 31 is slidably arranged inside the third sliding groove 3. The sliding component 31 is locked in the third sliding groove 3 and slides. An installation component 33 is provided on the top of the sliding component 31. The installation component 33 is used to install the zipper pull, that is, the zipper pull is inserted into the installation component 33, thereby completing the installation of both ends of the zipper pull.

[0026] A sliding frame 21 is slidably disposed inside the second sliding groove 2. The sliding frame 21 is engaged in the second sliding groove 2 and slides. A detection component is disposed inside the sliding frame 21 to detect the tensile strength of the zipper head. The detection component includes a tension gauge 22. A connecting rod 14 is disposed on one side of the sliding block 12. The tension gauge 22 is connected to the connecting rod 14 at the test point. A threaded tube 24 is disposed at the bottom of the sliding frame 21. A threaded rod 23 is disposed at the bottom of the second sliding groove 2. The threaded rod 23 is threadedly connected to the threaded tube 24. A knob 25 is disposed on the outside of the threaded rod 23. That is, by rotating the knob 25 on the outside, the sliding frame 21 slides inside the second sliding groove 2 through the threaded transmission. The tension gauge 22 is connected to the connecting rod 14 at the test point, so that the tension gauge 22 pulls the sliding block 12 and the mounting post 13, thereby detecting the tensile strength of the zipper head.

[0027] The mounting component 33 has an insert 35 at its bottom, and the sliding component 31 has a slot 34 inside. The insert 35 is installed and removed in the slot 34. The mounting component 33 includes multiple models to match different zipper heads, while the insert 35 is of a uniform model. It is removed and replaced in the slot 34 by inserting the insert 35, which facilitates the testing of different models of zipper heads. The bottom side of the third sliding groove 3 has an electric telescopic rod 32, which is connected to the sliding component 31. The electric telescopic rod 32 drives the sliding component 31 to extend and retract, thereby adjusting the distance between the mounting component 33 and the mounting post 13, which facilitates the testing of zipper heads of different lengths. The inside side of the slot 34 has a fixing component for fixing the insert 35. The fixing component includes a mounting groove 4, and a spring 44 is installed inside the mounting groove 4. A mounting plate 41 is provided on the spring 44, and the mounting plate 41 is slidably connected to the mounting groove 4. A slanted insert 42 is provided on one side of the mounting plate 41, and a rectangular groove 45 is provided on one side of the insert 35. The slanted insert 42 is installed and removed in the rectangular groove 45. A pull rod 43 is provided on the other side of the mounting plate 41. When the insert 35 is inserted into the slot 34, the slanted surface on the slanted insert 42 causes the insert 35 to press against the slanted insert 42, thereby pushing the slanted insert 42 into the mounting groove 4. After the insert 35 is installed, the spring 44 pushes the mounting plate 41 and the slanted insert 42, so that the slanted insert 42 is inserted into the rectangular groove 45, thus fixing the insert 35 to the mounting part 33. By pulling the pull rod 43 from the outside, the slanted insert 42 can be removed in the rectangular groove 45, which facilitates the disassembly and replacement of the mounting part 33.

[0028] The working principle of this utility model is as follows: When using the equipment, the pull tab is inserted into the mounting post 13, and the pull head is inserted into the mounting piece 33, thereby completing the installation of both ends of the zipper head. By rotating the knob 25 on the outside, the sliding frame 21 slides inside the second sliding groove 2 through threaded transmission. The connecting rod 14 is connected to the test point of the tension gauge 22, causing the tension gauge 22 to pull the sliding block 12 and the mounting post 13, thereby detecting the tensile strength of the zipper head. The sliding piece 31 is extended and retracted by the electric telescopic rod 32, thereby adjusting the mounting piece 33. The distance from the mounting post 13 facilitates the inspection of zipper heads of different lengths. The insert 35 is disassembled and replaced in the slot 34, which facilitates the inspection of different models of zipper heads. When the insert 35 is inserted into the slot 34, the inclined surface on the inclined insert 42 causes the insert 35 to press against the inclined insert 42, thereby pushing the inclined insert 42 into the mounting groove 4. After the insert 35 is installed, the spring 44 pushes the mounting plate 41 and the inclined insert 42, so that the inclined insert 42 is inserted into the rectangular groove 45, that is, the insert 35 is fixed to the mounting part 33.
