Service HotlineIn 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 flat gasket is a gasket whose upper and lower end faces are flat. The flat gasket used in the automobile differential is installed between the casing and the gear of the differential like the spherical gasket to reduce friction and reduce friction. Improve lubrication. The differential should accommodate severe bumps and be able to operate at high speeds for long periods of time in high and low temperature environments. Since both ends of the flat gasket currently used in the differential are smooth, or only one side end face of the flat gasket is provided with small concave points, during the high-speed operation of the differential, the flat gasket The lubrication of the contact surfaces is not ideal, and the friction between the contact surfaces is large, which is prone to failure.
T-bolts are a common type of bolts that tend to be used with rails when used. When the existing rail is in use, the T-shaped bolts are easily stuck and cannot reach the designated position well, and the use is not convenient enough, so that the T-shaped bolts cannot be well fixed.
A pull rivet, this kind of pull rivet has good installation performance, firm connection and long service life, but the defects are: first, after installation and use, if it is damaged, it cannot be reused; second, it is convenient to disassemble, and it also increases the possibility of theft ,. It is not conducive to safety; 3. There is still the possibility of movement in the circumferential direction of the collar, which will affect the riveting effect.
Screws are one of the most common fasteners in people's work and life. Because of their simple structure and low manufacturing cost, they are deeply loved by people. In many positions that need to be tightened, people use screws as fasteners; general screws It consists of a screw and a nut. The screw is provided with an external thread. The nut is generally a regular hexagonal body, which is convenient for people to tighten or loosen the screw with a wrench or other tools.
