Zipper is a connector that connects or separates articles through continuously arranged chain teeth. Now it is widely used in clothes, bags, tents and so on. Zipper consists of components, sliders, upper and lower blocks (front code and back code) or locking pieces. The zipper teeth are the key parts, which directly determine the lateral tensile strength of the zipper. Generally, a zipper has two belts, each belt has a row of fastener elements, and the two rows of fastener elements are staggered. The pull head clamp that chain teeth on both sides and slide through the pull piece, so that the chain teeth on both sides can be engaged or disengaged.
The zipper consists of a fixing block, a zipper strip, a zipper head, a hand-pulled block, a fixing frame, a fixing groove, a buckle block, a buckle groove and a rotating shaft, and is characterized in that the fixing block is arranged at one end of the zipper strip, and the zipper head is arranged on the zipper strip; The hand pull block is arranged in the middle of the zipper head through a rotating shaft, and the upper part of the hand pull block is arranged as a fixing frame; The clam block is arranged at one end of that fix block through a rotating shaft, the other end of the fixed block is arranged as a clamping groove, and the clamping block is match with the clamping groove; The lower part of the buckle block is provided with a fixing groove, and the fixing frame is matched with the fixing groove.
Although the production cost of the zipper disclosed in this patent is low, the structure of the zipper is too simple and can only be used in a simple environment, so it is necessary to design a zipper.
Technical realization elements:
The purpose of the present invention is to solve the above problems in the prior art and provide a zipper with strong practicability.
