Problems solved by technology

[0004] A zipper is very small, but the production process of the zipper is very complicated. In order to ensure that the zipper produced can enter the market for sale, the zipper needs to be inspected. Through the comparison of various indicators, it is often necessary to judge whether the quality of the zipper is qualified. It is to do a tear test on the zipper, and the zipper clamping device is usually used in the test. The clamping device currently used for the zipper tear test has the following disadvantages: 1. During the clamping process of the zipper chain belt, the chain belt The two ends are tightly clamped, the middle is loose, and the force is uneven, which affects the quality of the test. 2. The clamping force of the chain belt is small, and the chain belt is easy to loose during the tear detection process. 3. It is impossible to know the accuracy of the test. , inconvenient to use

Abstract

The invention discloses a clamping device for zipper tearing tests. The clamping device comprises: a base, clamping structures and locking structures. A front end plate is fixed to the top of the front side of the base, a rear end plate is fixed to the top of the rear side of the base, a sliding groove is formed in the top face of the base, two mounting frames are slidably connected into the sliding groove, two clamping structures are correspondingly mounted on the front sides of the two mounting frames, and the two clamping structures are symmetrically arranged, the locking structures corresponding to the clamping structures are mounted on the rear sides of the mounting frames; and each clamping structure comprises mounting bases, cams, a rotating shaft, matching wheels, end blocks, firstsliding rods, an upper pressing plate, a flange and a lower pressing plate. According to the clamping device for zipper tearing tests, a zipper belt is stressed evenly, the detection quality is improved, the zipper belt is large in clamping force and not prone to loosening, the detection accuracy can be known, and use is more convenient.

Description

technical field [0001] The invention relates to the technical field of zipper tear testing, in particular to a clamping device for zipper tear testing. Background technique [0002] With the development of human social economy and science and technology, zippers have developed from the original metal materials to non-metal materials, from a single variety with a single function to a multi-species and multi-specification comprehensive function. In the evolution process, its performance, structure, and materials are changing with each passing day, and it has a wide range of uses. It has penetrated into various fields such as aerospace, aviation, military, medical, and civil. Its importance and vitality, the zipper, as one of the ten most practical inventions for mankind in this century, has been recorded in the annals of history; [0003] The chain (zipper) is a connecting piece that relies on the chain teeth arranged continuously to make the items merge or separate. ) or lo...
