Embodiment Construction
[0027] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0028] refer to figure 1 , figure 2 , image 3 and Figure 4 . A zipper self-locking strength measuring device 1, comprising a frame body 2, a fixed part 3 is installed on one side of the frame body 2, and a guide channel 4 is arranged on the other side, and a movable part is slidably installed in the guide channel 4 5. There is an elastic piece 6 used to drive the two to move apart between the movable piece 5 and the fixed piece 3. The fixed piece 3 is provided with a first clamp for clamping the cloth belt 71 on one side of the zipper 7. part 8, the movable part 5 is provided with a second clamping part 9 for clamping the cloth tape 72 on the other side of the zipper 7, and the elastic force of the elastic part 6 is the same as the maximum self-locking strength of the zipper 7 to be measured quite. The elastic part 6 is at least one fourth compre...

A device for measuring zipper self-locking force comprises a frame body, a fixing member which is arranged at one side of the frame body, a guide channel which is arranged at the other side of the frame body, a moving member which is arranged inside the guide channel in a slidable mode, an elastic member which is arranged between the moving member and the fixing member and drives the two members to move in opposite directions. The fixing member is provided with a first clamping part which is used for clamping a strap of one side of the zipper; the moving member is provided with a second clamping part which is used for clamping a strap of the other side of the zipper; the elastic force of the elastic member equals to the maximum self-locking force of the zipper to be measured. According to the device, a user only needs to set a rated elastic force value which equals to the maximum self-locking force of a zipper to detect whether the self-locking force of the zipper meets a required self-locking force or not; the device is simple to use and easy to carry, and has strong mobility and applicability.
Description
technical field [0001] The invention relates to a zipper characteristic testing device, in particular to a zipper self-locking force measuring device. Background technique [0002] Self-locking zippers are composed of chain teeth, sliders, limit codes or locking pieces. Among them, the chain teeth are the key part, which directly determines the side pull strength of the zipper. Generally, the zipper has two chain belts, each of which is made with a row of chain teeth, and the two rows of chain teeth are arranged alternately. The slider clamps the chain elements on both sides, and the chain elements on both sides can be engaged or disengaged by sliding with the aid of the slider. [0003] For now, one of the most important indicators in evaluating the quality of self-locking zippers is the self-locking strength. Many zippers need to measure their self-locking strength in order to know whether the zipper meets the relevant industry standards. [0004] For now, the existing ...
