Service Hotlinescrew is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the mechanism of the object step by step. When using screws to fasten objects and parts, it is often necessary to use screws with spring washers and flat washers to lock and fix the relative position, so as to improve the stability of the fastening connection and make the screws less prone to loosening. However, in the prior art, the method of manually inserting the spring washer and the flat washer in sequence is generally used, which not only increases the workload of the staff, but also makes the installation efficiency relatively low. On the other hand, the traditional screw with a gasket only has the function of fixing, Without the function of sealing, it cannot be applied to special equipment such as oil tanks and airtight cabins. Therefore, it is necessary to design a screw that can reduce the workload and have its own sealing structure.
The lifting ring nut is a part that tightly connects the mechanical equipment. It can be connected together through the inner thread, the lifting ring nut and the screw of the same specification. Lifting ring nuts are often used in conjunction with externally threaded columns to lift various equipment, such as molds, chassis, motors, etc.
hand screw is a screw with a plastic head, and the user fixes the hand screw by turning the plastic head by hand. At present, a hand-tight screw is disclosed in the market publication number CN202203253U, which includes a plastic head and a screw rod, the plastic head and the screw rod are connected together, and the height of the plastic head is higher than that of ordinary screws, and the height is 9cm. The screw of the hand screw is fixed in the plastic head by glue. After a period of use, the aging of the glue leads to the loosening of the screw and the plastic head. When the plastic head is stressed, the screw rod comes out of the plastic head, which affects the normal use of the hand screw.
Two combination screws are mostly used for the connection between thin metal plates, and play a connecting role. When connecting, first make a threaded bottom hole for the connected piece, and then screw the combination screw into the threaded bottom hole of the connected piece. Since the threaded surface of the combination screw has high hardness, the inner thread can be tapped in the threaded bottom hole of the connected piece to form a connection.
Guangdong Yueluo Hardware Industry Co., Ltd. provides a nut provided by Yueluo, which includes an internal thread. is an arc curve. Compared with the nut of the same type, the normal pressure and friction force of the nut are increased, the thread is not easy to loosen, and the bolt and nut are in surface contact, so it is not easy to cause stress concentration and local material yield, which effectively improves the tightening force of the bolt and nut. Stability, increase fastening reliability.
