AI Technical Summary
Technical Problem
Existing zipper fatigue testing devices can only test straight zippers and cannot effectively test zippers installed on curved suitcases. Furthermore, manual testing is time-consuming and labor-intensive.
Method used
A testing device was designed, comprising a base plate, support column, platform, sliding box, sliding block, upright column, hook, and drive assembly. The sliding box and sliding block are moved by a cylinder and a motor to simulate the opening and closing operation of a zipper, thereby achieving fatigue testing of a bent zipper.
Benefits of technology
This technology enables effective fatigue testing of bent zippers, avoiding the time-consuming and labor-intensive nature of manual inspection and improving testing efficiency.

Abstract
This utility model relates to the field of testing equipment technology and discloses a zipper fatigue testing device. The testing components include a sliding box, a sliding block slidably disposed inside the sliding box, a column fixedly disposed above the sliding block, a hook fixedly disposed on the column, a first driving component disposed on the base plate for driving the sliding box to move back and forth, and a second driving component disposed on the sliding box for driving the sliding block to move left and right. A sliding groove A is formed through the upper and lower parts of the platform, located on the front side of the column. Sliding grooves B are formed through the upper and lower parts of the platform, located on the left and right sides of sliding groove A and communicating with sliding groove A. The column is located in sliding groove B, and the hook is located above the platform. This utility model has the beneficial effect of conducting fatigue testing on zippers on trolley cases, solving the problem that zippers installed on trolley cases are bent, making it impossible to test zippers on trolley cases; and that manual testing would be time-consuming and labor-intensive.
