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.
Washers are accessories used between the nut and the connecting piece to disperse the pressure of the nut on the connected piece, thereby protecting the connected piece. The general gasket is a flat gasket, which is easy to loosen after long-term use, and the stability is not high. There are also some elastic washers, which have poor elastic stability and short service life.
A medical self-locking screw, wherein the medical self-locking screw is composed of an outer screw and an inner screw, the outer screw includes a fixedly connected fitting body and the front part of the outer screw, and the front part of the outer screw includes a fixed connection The outer screw rod body and the outer screw head are provided with fixed external threads on the periphery of the outer screw rod body, and a backstop ring is provided on the periphery of the matching body;
Supporting T-bolts for pre-embedded channels, including hot-rolled pre-embedded channels, the lower part of the pre-embedded channel is provided with a longitudinal opening, and the head of the T-bolt enters from the opening and is clamped in the pre-embedded channel. There are plane teeth at the connection between the buried channel and the T-bolt, and the T-bolt has a tooth-shaped structure matched with the plane teeth. The direction of the teeth is parallel to the slotting direction, and the tooth-shaped cooperation achieves anti-slip effect. However, when the nut tightened on the T-bolt becomes loose, it will cause the T-bolt to move into the embedded channel and lose the toothed fit, thus changing the fixed position of the T-bolt in the embedded channel.
screw is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the mechanism of the object step by step. A screw is a common term for fasteners, an everyday colloquial language. Screws are indispensable industrial necessities in daily life: tiny screws used in cameras, glasses, clocks, electronics, etc.; general screws in televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large screws are used. Screws and nuts; transportation equipment, airplanes, trams, automobiles, etc. are used together with large and small screws. Screws have important tasks in industry. As long as there is industry on earth, the function of screws will always be important. The screw is a common invention in people's production and life for thousands of years. According to the application field, it is a great invention of human beings.
