Problems solved by technology

This method can only measure the fatigue strength and service life of the zipper when it is arranged in a straight line (that is, the zipper is arranged in a straight line after the zipper slider is opened), but the existing zippers are widely used, and more are used in curved arrangements such as Tents and other occasions, so the fatigue strength and service life measured by this method do not match the fatigue strength and service life in actual applications

Embodiment Construction

[0017] A method for measuring the fatigue strength of a zipper. The zipper includes a first tape with a zipper tooth row, a second tape and a slider; the first tape is fixed on the device in an arc, and the second tape passes through the The equipment is subjected to a predetermined tension; the upper ends of the first tape and the second tape are fixed on the equipment; the equipment drives the zipper head to reciprocate, so as to measure the fatigue strength and service life of the zipper.

[0018] Depending on the type of zipper, the reciprocating stroke of the zipper head, the clamping width of the first and second spring clips, the distance between the first spring clip and the second spring clip, and the weight of the weight can be adjusted separately.

[0019] The equipment drives the zipper head to reciprocate at a constant speed, 30 reciprocating movements per minute, and records the time and times of reciprocating movements, so as to measure the fatigue strength and s...

Abstract

This invention discloses a chain fatigue strength method and device, wherein the method can ensure the fatigue strength and the usage life measured match the real situations; and the device is processed by the above method, which can easily measure the accurate fatigue strength and usage life.

Description

technical field [0001] The invention relates to a method and equipment for measuring the fatigue strength of a zipper. Background technique [0002] The existing social method for measuring the fatigue strength of zippers is generally to fix the upper ends of the first tape and the second tape of the zipper on the equipment, and the first tape and the second tape are respectively subjected to a predetermined tension through the equipment. , through the equipment to drive the zipper head to reciprocate, so as to measure the fatigue strength and service life of the zipper. This method can only measure the fatigue strength and service life of the zipper when it is arranged in a straight line (that is, the zipper is arranged in a straight line after the zipper slider is opened), but the existing zippers are widely used, and more are used in curved arrangements such as Tents and other occasions, so the fatigue strength and service life measured by this method do not match the fa...
