Service HotlineGaskets are mechanical components used for cooperation between two objects, which play a role in preventing pressure, corrosion and leakage of pipes from natural thermal expansion and contraction between two objects. By using the gasket in conjunction with the bolt and nut, the gasket can increase the contact area between the bolt and nut and the metal parts, and play the role of buffering and shock absorption to prevent the thread from loosening.
The technical solution of Guangdong Yueluo Hardware Industry Co., Ltd. is: Guangdong Yueluo Hardware Industry Co., Ltd. discloses an anti-dropping nut, which includes a lock, a lock plate, a nut body, a lock ring and a lock claw. The lock ring and the nut body When used together, the lock ring is a circular ring, the inner diameter of the lock ring is larger than the inner diameter of the circumscribed circle of the nut body, the outer diameter of the lock ring is smaller than the inner diameter of the lock buckle, the lock disk is an arc-shaped metal plate, and the number of lock disks is greater than or equal to three. One short side end of the lock plate is connected to the nut body, and the other end of the lock plate is connected to the lock pawl, the lock plate is inclined to the outside of the nut body, and the lock catch is arranged on the outer side of the connection end between the lock pawl and the lock plate. On the side, the lock is a concave arc.
Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread), which needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the slotting device 4 includes a motor 41 and a motor 43, the cutting wheel 42 is fixedly arranged at the output end of the motor 41, and the motor 41 drives the cutting wheel 42 to rotate to open the screw. slot, the motor 43 is fixedly arranged on the workbench 1, the motor 41 is arranged on the motor 43, a track 47 is arranged between the motor 41 and the motor 43, the motor 41 can reciprocate through the track 47, and when the screw is slotted, the motor 41 drives the cutting wheel 42 to move in the direction of the screw. When the slotting is finished, the motor 41 drives the cutting wheel 42 to retract. The fixed wheel 48 is arranged at the output end of the motor 43. The fixed wheel 48 is located directly below the cutting wheel 42. The surface of the middle screw is in contact, and the motor 43 drives the fixed wheel 48 to rotate to grind and polish the surface of the slotted screw to make the surface smooth. Preferably, the direction of rotation of the cutting wheel 42 and the fixed wheel 54 is opposite.
Many standoffs are used in sheet metal and aluminum profile processing. However, the existing pressure riveting nut column generally adopts a clearance fit between the pressure riveting and the pressed plate, which has no effect on the general pressure riveting, but it has high surface quality requirements for aluminum profiles, especially Painting aluminum profiles will have a certain impact. First, because the bottom holes of pressure riveting on aluminum profiles are generally processed on ordinary punching machines, a tapered hole with a horn will be generated, which will further increase the gap between the pressure riveting nut columns. Make the mutual tightening force smaller, causing some aluminum profile components to loosen the riveting nut when installing screws, resulting in unqualified surface quality. Therefore, we urgently need a way to reduce the matching gap with the bottom hole of the aluminum profile pressure riveting. The pressure riveting standoff is used to increase the wrapping force between the pressure riveting standoff and the aluminum profile hole.
