Description

Technical Field

[0001] This utility model relates to the field of zipper zipper smoothness testing technology, and in particular to a clamping device for a zipper zipper smoothness testing pull tab. Background Technology

[0002] Currently, the standards QB / T2171, QB / T2172, and QB / T2173 for testing the smoothness of zipper closure for nylon, injection molded, and metal zippers all use the same type of smoothness tester. Some zipper closure smoothness testing equipment on the market uses hook-type clamping devices for the zipper pull tabs, which achieve zipper closure by hooking onto the holes in the zipper pull tab. Such clamping devices cannot guarantee smooth clamping for zipper pull tabs without holes. Some clamps cannot move vertically, and when the zipper pull tab is of a certain length, the clamp cannot achieve stable clamping through vertical movement. Some two-piece clamping devices require manual joining of the two different clamping surfaces during sample loading, which is time-consuming, labor-intensive, and inconvenient for testing technicians. Furthermore, for some thinner zipper pull tabs, the clamping device is prone to slippage. For some irregularly shaped, three-dimensional, or doll-shaped zipper pull tabs, the clamping device may not be suitable, failing to achieve stable clamping and hindering the diversification and promotion of product testing.

[0017] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a clamping device for a zipper pull tab for testing the smoothness of zipper closure. It includes a smoothness tester body 1, a zipper body 10, and a pull tab body 11. A protruding rod 2 is installed on one side of the top of the smoothness tester body 1. A clamping mechanism is provided on one side of the protruding rod 2. The clamping mechanism consists of a clamping main plate 4 and a clamping panel 5. A threaded groove is formed on one side surface of the protruding rod 2, and an internally threaded nut 3 is installed inside the threaded groove. A longitudinal sliding groove 15 is formed on the surface of the clamping main plate 4. The clamping main plate 4 and the protruding rod 2 are locked and fixed together by the internally threaded nut 3. A slot 13 is horizontally formed on one side of the main board 4. A protrusion 14 corresponding to the position of the slot 13 is fixedly set on one side of the clamp panel 5, with one end of the protrusion 14 inside the slot 13. A threaded hole 17 is formed on the surface of the main board 4, and a long screw 6 is installed inside the threaded hole 17. A round hole 18 corresponding to the position of the threaded hole 17 is formed on the surface of the clamp panel 5. A wing nut is fixedly set on one end of the long screw 6 through the outer surface of the round hole 18. A telescopic spring 9 is sleeved on the surface of the long screw 6 between the clamp main board 4 and the clamp panel 5. Clamping blocks are fixedly installed on the opposite sides of the bottom of the main board 4 and the clamping panel 5. The two clamping blocks are bent inward at a certain arc to form a gripper. The bottom of the gripper is equipped with a zipper body 10, and the pull tab body 11 on the surface of the zipper body 10 is located inside the gripper. By longitudinally opening a sliding groove 15 on the surface of the clamping main board 4, the sliding groove 15 on the clamping main board 4 can be moved up and down on the side of the protrusion 2 on the body of the light slip tester according to the length of the pull tab body 11 to control the clamping position of the main board. The combination of the slot 13 and the protrusion 14 facilitates the clamping of the main board. The clamp panel 5 is inserted into the slot 13 on one side of the clamp main board 4. Through the combination of the elongated screw 6, the telescopic spring 9, the threaded hole 17, the round hole 18 and the wing nut, it is easy for personnel to quickly limit the installation of the zipper pull body 11 between the two clamping blocks at the bottom of the clamp main board 4 and the clamp panel 5. This clamping device has a simple structure, is easy to operate, and saves time and effort. It is conducive to the testing agency to efficiently and accurately clamp the zipper pull body 11, so as to obtain accurate and stable test results. It is beneficial to its application and promotion in the zipper testing market.

[0018] like Figure 1 , Figure 2As shown, a platform 12 is fixedly installed on one side of the bottom of the main body 1 of the slip tester. A pressure block 7 is provided on one side of the top of the platform 12. Two threaded through holes are opened on the surface of the pressure block 7. A Torx screw 8 is installed inside the two threaded through holes. A threaded groove corresponding to the position of the threaded through holes is opened on one side of the platform 12. The bottom end of the Torx screw 8 passes through the threaded through hole and extends to the inside of the threaded groove. One end of the zipper body 10 is located between the platform 12 and the pressure block 7. A groove is opened at the position of the zipper body 10 at the top of the platform 12. The combination of the pressure block 7, Torx screw 8, platform 12, threaded through holes and threaded groove makes it easy for personnel to limit and fix one end of the zipper body 10, and avoid the zipper body 10 from shifting during the slip test, which would lead to inaccurate testing.

[0019] like Figure 1 As shown, when the gripper formed by the clamping block at the bottom of the clamping main board 4 and the clamping panel 5 holds the object, a hollow structure is formed on the inner side of the top. The hollow structure can accommodate the irregularly shaped or doll-shaped pull tab body 11 with a three-dimensional tail end, thus promoting the applicability of firmly clamping the diverse pull tab body 11 and meeting the diverse testing needs of customers for the pull tab body 11.

[0020] like Figure 3 As shown, anti-slip strips are provided on the relative clamping surfaces of the gripper; by providing anti-slip strips on the relative clamping surfaces of the gripper, the gripper can hold the pull tab body 11 more firmly and is less likely to shift.

[0021] like Figure 2 As shown, four reserved mounting holes 16 are provided on the surface of the placement platform 12; by providing four reserved mounting holes 16 on the surface of the placement platform 12, it is convenient for the placement platform 12 to be installed on the designated testing platform.

[0022] Specific working principle:

[0023] The clamping main board 4 and clamping panel 5 are connected by a long screw 6. The operator can tighten the clamp by rotating the wing nut at one end of the long screw 6 clockwise and loosen it by rotating it counterclockwise. The surface of the long screw 6 between the clamping main board 4 and clamping panel 5 is fitted with a protrusion 14. When the clamp is loosened by rotating the long screw 6 counterclockwise, the spring relaxes in the length direction and pushes the clamping main board 4 and clamping panel 5 to move left and right, which can help loosen the clamped pull tab body 11, thus reducing the need for manual movement of the two clamping panels. The long screw 6 passes through the clamping main board 4 for a certain length. When the clamp is loosened by rotating the long screw 6 counterclockwise, the clamping main board 4 and clamping panel 5 of the clamp are still on the long screw 6, maintaining the state of waiting for the next clamping of the pull tab body 11, thus reducing the manual operation of aligning the screw with the clamping panel 5 and initially screwing the screw into the clamping main board 4, realizing simple and efficient clamping of the pull tab body 11.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
