The hexagonal flange surface nut mainly includes a nut body, a flange surface is fixed at one end of the nut body, and a cap is fixed at the other end of the nut body. Has good sealing and corrosion resistance. The hexagonal flange surface nut mainly includes a nut body, a flange surface is fixed at one end of the nut body, and a cap is fixed at the other end of the nut body; since the cap is set on the nut body, it has the Better sealing can effectively prevent rain, moisture, dust and other harmful substances from immersing in the nut body, prevent the nut body from rusting, and greatly extend the service life of the hexagonal flange nut.
In the existing production technology, such as construction machinery, double nuts are often used to fasten the workpiece. With the long-term vibration in the working environment, there is a thread gap between the nut and the bolt, and there is no self-assembly between the nut and the bolt. Locking action, the relative displacement between the nut and the bolt will occur under the action of vibration, resulting in the loosening of the nut and the bolt and the loss of the tightening effect.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is a kind of anti-loosening cylindrical pin with grooves specially designed for the multi-link transmission paint mixing mixer, which is specially designed for the problems existing in the above-mentioned prior art. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to realize through the following technical solutions: a kind of anti-loose cylindrical pin with groove, wherein: a plurality of axial V-shaped grooves are provided on the cylindrical pin, and the V-shaped groove Arrange evenly on cylindrical pins. There are three to four axial V-shaped grooves on the cylindrical pin. When Guangdong Yueluo Hardware Industry Co., Ltd. is in use, the cylindrical pin with V-shaped groove is installed in the vertical shaft, and cooperates with the U-shaped groove on the connecting rod to transmit torque. The cylindrical pin of the V-groove structure is an interference fit with the mounting hole of the vertical shaft. The biggest feature of Guangdong Yueluo Hardware Industry Co., Ltd. compared with the existing technology is that the cylindrical pin is used as a vertical shaft to connect with the connecting rod for torque transmission, which gives full play to the impact resistance and fatigue resistance of the cylindrical pin. The cylindrical pin has an interference fit with the pin hole, and each edge of the V-groove structure distributed on the cylindrical pin body will penetrate into the inner wall of the pin hole to prevent loosening.
