Fasteners play a very important role in the installation of the main engine. Complex products such as airplanes, automobiles, trains, elevators, air conditioners, and computers all have the problem of installing components on thin plates. There are two traditional installation processes. One is The first is to tap the internal thread on the thin plate, but when the internal thread is tapped on the thin plate below 6 mm, the installation is often not firm because the number of threads is too small, and even the connection fails due to the broken thread when the force is applied; the second way It is a process of welding nuts on a thin plate, which easily leads to deformation of the thin plate and uneven welding surface. Sometimes the welding is not strong and the nut falls off when the force is applied, resulting in damage to the installation. The development of rivet nuts has solved the problem of installing components on thin plates, because rivet nuts combine the characteristics of nuts and rivets, and play an increasingly important role in fastener products. However, with the extensive use of rivet nuts in the electromechanical and mechanical industries such as automobiles, aviation, railways, refrigeration, elevators, etc., ordinary rivet nuts can no longer meet the special assembly requirements of many mechanical and electromechanical products, such as good sealing during assembly.

The tie rod and joint of the high-voltage isolating switch are often connected by driving an elastic cylindrical pin into the connecting pin hole. The traditional assembly method is to prevent the tie rod and joint from the V-block, and hold the elastic cylindrical pin to align the connecting pin hole. Then hit it with a hammer. Since the elastic cylindrical pin is small, it is easy to injure people's hands by adopting this assembly method, and at the same time, the elastic cylindrical pin is not positioned accurately, which causes large assembly errors and low assembly efficiency.

At present, the screws used by people are not provided with a device that does not loosen, especially in some key parts, if the screws are loosened, it will cause heavy losses. In order to overcome the current situation, there is no device on the screw to prevent the screw from loosening, which may cause heavy losses. Guangdong Yueluo Hardware Industry Co., Ltd. The inner part will not be loose, and it will save people the trouble of maintenance and reduce the hidden danger of accidents. The solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve its technical problems is to make a special screw and nut, set a stop groove on the screw, and then set a stop rod on the nut. After the screw is tightened , let the backstop rod be stuck in the backstop groove to prevent the screw from loosening. The beneficial effect of Guangdong Yueluo Hardware Industry Co., Ltd. is to ensure that the screws will not loosen during the service period, reducing the hidden danger of accidents and reducing the maintenance rate. Guangdong Yueluo Hardware Industry Co., Ltd. is further described below in conjunction with the accompanying drawings and embodiments

Claw ingot screw

In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. discloses a tamper-proof nut, which includes an upper part, a lower part, and an inner threaded hole penetrating the upper part and the lower part. The cross section of the inner threaded hole is circular, so the The lower part is an equilateral triangle cylinder, and the apex of the equilateral triangle cylinder has an arc structure, and the arc structure includes a left arc part and a right arc part with the angle bisector as the center of symmetry, and the lower part has an arc structure. A tamper-proof portion protruding from the lower surface is formed, and the tamper-proof portion is arranged at the left arc portion or the right arc portion.
