The Chinese Patent Application No. 201320368989.2 discloses a pin, which includes a pin body and a cylindrical body part integrally provided with the pin body, a convex tip is provided on the cylindrical body part at one end of the pin body, and the convex The tip is horizontally arranged around the cylindrical body part and protrudes from the surface of the cylindrical body part. The connection between the cylindrical body part and the convex tip is provided with an inclined plane. Although this pin solves the problems of easy loosening and falling off to a certain extent, However, this kind of pin still has the problem of loosening and falling off in the case of bad working conditions and severe vibration.

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above shortcomings and provide a limit screw. The technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. is realized in the following way. Its structure is composed of screws, hexagonal copper posts and limit necks. The left end of the limit neck is open, the hexagonal copper column is communicated with the inside of the limit neck, and the inside is provided with screw threads. The design length of the screw thread in the hexagonal copper column is 1/3-2/3 of its own length. The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are (3), which can effectively prevent the problem of poor memory contact caused by the increase of the deformation of the motherboard due to the warping and deformation of the motherboard during installation and fixation, and can effectively control the amount of deformation effect.

Riveting is a method for combining two pieces of metal. Therefore, riveting technology is often used to fasten rivets such as nuts or rivets to metal sheets.

Bolts made of high-strength steel, or bolts that require a large pre-tightening force, can be called high-strength bolts. High-strength bolts are mostly used for the connection of bridges, rails, high-voltage and ultra-high-voltage equipment. The fracture of this kind of bolt is mostly brittle fracture. High-strength bolts applied to ultra-high pressure equipment need to be prestressed to ensure the sealing of the container.

In the current production process, the inner wall of the circlip is quantitatively and evenly lubricated, and then the rotating shaft is inserted into the circlip, so that the rotating axis can rotate in the circlip, thereby realizing the rotation function of the sun visor. However, since the circlip is tightly fitted with the rotating shaft, during the insertion process of the rotating shaft, the front end of the circlip can easily push the grease from the opening at one end of the circlip to the opening on the other end of the circlip, so that the rotating axis and the inner wall of the circlip are easily connected. There is little or no grease left between them, which can easily lead to a lack of lubrication between the shaft and the circlip, and dry friction between the shaft and the circlip, resulting in a series of problems such as abnormal noise, difficult operation, and poor durability.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: GB/T923 cap nuts, black inch screws, color zinc 8.8 screws, triangle / round nuts and other products, we can provide you with The right fastener solution for you.
