Screw head table

The retaining ring with an open ring structure is a commonly used mechanical part. It has standardized design standards. Its main function is to fasten the ring-shaped parts on the shaft, which can prevent other parts mounted on the shaft from moving. kinds of fasteners. In the prior art, the retaining ring is mainly processed by stamping, which has the following defects: 1. The material utilization rate is low;

Compared with the prior art, the technical effect of Yueluo Company is: during the screwing process of the nut, the tube wall of the nut is elastically deformed so that the convex ring on the screw is matched with the groove on the nut, and the slope of the convex ring matches the groove. The groove wall is abutted against to limit the relative position of the nut tube and the screw shaft in the axial direction, which not only ensures the reliability of the threaded connection, but also achieves a significant anti-loosening and anti-falling effect. After the threaded connection, excessive force is applied to remove the nut and screw, so that it can be reused to save costs.

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.

At present, in the production workshop, there is no special tool for removing rivets such as skew, wrong rivets, and multiple rivets. When removing these rivets, workers use homemade rivet removal tools, use a sledgehammer to remove the rivet head, and then use a sharp tool to remove the rivet rod. eject. During the removal operation, sometimes the rivet head will fly out, the speed is high, the danger is extremely high, and the labor intensity is high, which has caused many industrial accidents.
