screw is a common connecting piece, a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the parts of the object step by step. 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. A traditional screw is generally set as a screw head at one end and a screw rod at the other end, which cooperates with an external nut to fasten the connector between the screw head and the nut. However, such as some home appliance modules, chassis and other electrical appliances, the modules and boxes fixed by traditional screws often fasten many parts together by screws. During maintenance, it is necessary to disassemble all parts of the maintenance part, which is very troublesome. Therefore, a new type of screw structure that can be connected at both ends and can realize layered installation is required. During maintenance, only the connecting layer of the maintenance part needs to be disassembled, and neither the exterior nor the interior needs to be disassembled.
Nylon self-locking nut Nylon self-locking nut is a new type of high anti-vibration and anti-loose fastening parts, which can be used in various mechanical and electrical products with a temperature of -50 to 100 °C. Aerospace, aviation, tanks, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products and various types of machinery have a sharp increase in the demand for nylon self-locking nuts, because its anti-vibration and anti-loosening performance is much higher than other Various anti-loose devices, and the vibration life is several times or even dozens of times higher. At present, more than 80% of the accidents of mechanical equipment are caused by loose fasteners, especially in mining machinery, and the use of nylon self-locking nuts can prevent major accidents caused by loose fasteners.

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a new type of open blind rivet suitable for riveting of aluminum Al, steel St, and stainless steel SST sheets with foam material in the middle. The new rivet improves the mandrel process, adopts aluminum mandrel, the head of the mandrel has a pit for easy deformation, and there is a conical stop groove above the breakpoint of the mandrel. The mandrel can be caught by the stopper to prevent the nail head from being exposed. At the same time, lock the core rod not to loosen.
