Summary of information:We have more than ten years of experience in screw industry production, the main products are: iron galvanized pull rive...

The pull-out type positioning pin and the tie-suspended type positioning pin are in the form of a straight cylindrical shape. The pull-out locating pin is temporarily pulled out from the connected piece of the tooling, and it is in a loose state; the tail of the tie-suspended locating pin is connected with a tie such as iron wire or string to the connecting piece of the tooling. After the locating pin is pulled out, the tie Suspended on tooling. The main disadvantages of the two types of positioning pins are as follows: First, the suspension straps are easy to fall off after long-term wear, and the pull-out positioning pins of the same parts are not convenient for on-site storage and placement, and are usually placed on the nearby ground at will; All kinds of positioning pins are prone to position transfer, forgetting and losing, which affects the reset of the tooling and the subsequent manufacture and assembly of aircraft products.

The technical solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve the problems of the prior art is: a patch nut, which is characterized in that it includes a nut body, and the nut body has a welding end face, and the edge of the welding end face forms a The serrated teeth protruding outwards of the ring.

Stainless steel screw wire is also called stainless steel cold pier wire, which is mainly used for various fasteners, such as mechanical parts, electronic application parts, etc. Corresponding anti-corrosion properties and mechanical properties can be obtained according to different materials. In order to obtain a better formability during cold forging, choose high quality. The appropriate material of the wire is particularly important.

Screws and nuts, as the most commonly used fastening devices, have the defect that they may loosen and fall off, especially those in a long-term vibrating environment are more likely to loosen and fall off. Additional anti-off parts such as anti-off washers and anti-off caps are added, so that an extra anti-off part is used in the fastening process, and these anti-off parts are sometimes difficult to find when they are not always needed and are inconvenient to use.

An anti-falling nut, comprising a lock buckle 1, a lock plate 2, a nut body 3, a lock ring 4 and a lock claw 5, the lock ring 4 and the nut body 3 are used together, the lock ring 4 is a circular ring, and the lock ring 4 is a ring. The inner diameter of the ring 4 is larger than the inner diameter of the circumscribed circle of the nut body 3, the outer diameter of the lock ring 4 is smaller than the inner diameter of the lock 1, the lock plate 2 is an arc-shaped metal plate, and the number of the lock plates 2 is greater than or equal to three. One end of the short side is connected to the nut body 3, the other end of the lock plate 2 is connected to the lock pawl 5, the lock plate 2 is inclined to the outside of the nut body 3, and the lock buckle 1 is provided at the connection end of the lock pawl 5 and the lock plate 2. The outer side of the lock buckle 1 is a concave arc.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: high-tech production, GB70 cup head bolts, national standard 10.9 screws, aluminum sealing rings and other products, we can provide you with suitable fasteners for you solution.
