Service HotlineThe general nut will loosen itself due to vibration and other reasons during use. In order to prevent this phenomenon, the self-locking nut was invented. The main functions of self-locking nuts are anti-loose and anti-vibration. For special occasions. Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with nylon rings, those with neck closures, and those with metal anti-loosening devices. They are all effective torque type lock nuts (refer to GB/T3098.9-2002 national standard)
In view of the above situation, the technical problem to be solved by Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a self-expanding semi-solid installation rivet, the purpose is to solve the existing connection between plastic shells, lightweight plates, insulating materials, circuit boards, or any other In the case of thin, light-weight materials, the grip and bonding force of the rivet itself on the mounting surface is weaker than that of the rivets that are screwed and installed by manual operation. The rivet structure needs to be improved and strengthened when the material is installed.
A nut provided by Yueluo. The nut is in the shape of a casing and is provided with a threaded section. One end of the threaded section is provided with a protrusion on the wall of the hole. The nominal size of the segment or the distance from the rear end of the lug to the hole core in the screw-in direction is smaller than the nominal size of the threaded segment.
In order to overcome the above problems, Guangdong Yueluo Hardware Industry Co., Ltd. provides a screw that can be quickly installed and removed. Using the principle of lever, press the handle downward, and the screw can form a backward force through the connecting piece. Press the screw and nut tightly; lift the handle, the screw forms a forward force, and the screw can be removed. Thus, the time and manpower for screwing during installation and disassembly are reduced. The solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve its technical problems is that the entire screw includes a screw rod, a nut, a connecting piece, a circlip, a positioning pin, a small shaft, a fixed piece, a base, and a handle; the screw is connected by the small shaft at the upper end. At the upper end of the connecting piece, the handle is connected to the lower end of the connecting piece, and the front end of the handle is connected to the base fixing piece through a positioning pin. There are gaps at both ends of the small shaft, and the small shaft is installed through the circlip. The front end of the handle can only be rotated on the positioning pin. Due to the lever principle, when the handle is pressed down, it will drive the screw at the front end of the connecting piece, so that the screw generates a backward force and tightens the screw and the nut. On the contrary, when the handle is pulled up, the screw generates a forward force, so that the screw can be easily removed. The beneficial effect of Guangdong Yueluo Hardware Industry Co., Ltd. is that the quick-opening screw saves the time and labor of repeatedly twisting the nut during installation and disassembly. The installation and removal process is simple.
The hexagonal nut is used in conjunction with screws, bolts and screws to connect and fasten parts. Among them, the Type 1 six-purpose nut is the most widely used. The C-level nut is used for machines, equipment or structures with rough surface and low precision requirements; A-level and B-level nuts are used for relatively smooth surfaces and high precision requirements. machine, equipment or structure. The thickness M of the type 2 hexagon nut is thicker, and it is mostly used in occasions where assembly and disassembly are often required. The thickness M of the hexagonal thin nut is relatively thin, and it is mostly used in situations where the surface space of the connected parts is limited.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: hexagonal K-type nut with teeth, anti-slip flanged nut with gasket, DIN935 nut, 8-grade fine pitch black hexagonal nut and other products , we can provide you with a fastener solution that suits you.
