In pressure vessels such as oil cylinders, the existing sealing structures are all seals (such as O-rings, etc.) plus a retaining ring. The cross-sectional shape of the retaining ring is generally rectangular. The retaining ring of this shape is limited in the sealing structure. It protects the sealing ring and does not participate in the sealing effect.
screw is a type of fastener that cooperates with threaded holes for combining various parts into one assembly and making the parts easy to assemble or disassemble. However, when the assembly containing the screw is used in a special environment, such as outdoor use or use in a liquid environment, there are requirements for preventing the leakage of liquid through the screw joint and preventing the screw from loosening at the screw joint. The screw structure does not have such a function. In the prior art, when there is a need for leakage prevention and loosening of the screw, a rubber washer is usually added between the screw head of the screw and the locking surface of the locked part, or the thread part of the screw is wrapped to prevent Leakage tape and then add anti-loose washers between the screw head of the screw and the locking surface of the locked part, so as to achieve the purpose of preventing leakage and loosening. However, the use of washers not only increases the thickness and weight of the assembly, but also requires an additional process during assembly, which is labor-consuming and labor-intensive. In the process of screwing, it is easy to cause uncertainty to the rubber washers due to the shear stress of the screws. Leakage occurs due to damage and deformation, and the practice of wrapping leak-proof tape around the screw teeth is often prone to damage to the threaded holes.
In view of the deficiencies of the prior art, a simple structure is provided, which can ensure that the nut body and the washer are assembled together during the production of the wheel nut, and will not be separated from each other in any occasion, so as to ensure the reliability of the assembly, and the nut will no longer appear. The wheel nut assembly that needs to be reassembled after use or placement saves time and effectively improves the convenience of the wheel nut when it is used or placed
In the prior art, there are also automated equipment for riveting and assembling of hardware and handles; however, for the existing automated equipment, how to automatically and efficiently realize rivet feeding is particularly important.
