In the prior art, the independent pocketed spring is to encapsulate the springs in bags independently, connect each independent pocketed spring side by side, and then cover it with a large non-woven fabric to form a Spring cushions. This spring mat structure has many disadvantages: 1. Uneven force and low hardness; 2. Easy to deform, pit, low flatness and unsightly; 3. The spring directly contacts the non-woven fabric, causing wear and tear, and the life of the spring mat relatively short.

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.

The key connection is a typical mechanical connection, which is usually used to connect the parts on the shaft and to fix them circumferentially and realize torque transmission. Key connection can be divided into flat key connection, semicircular key connection, wedge key connection and tangential key connection, among which flat key connection is widely used in practical engineering because of its simple structure, good alignment and convenient manufacturing. During operation, torque is transmitted through the contact between the sides of the key and the sides of the shaft and hub grooves. In order to ensure the transmission accuracy, the flat key structure generally adopts the transition fit. Due to its structural characteristics and working conditions, it is difficult to use ordinary mechanical tools to lift and pull out during the maintenance process. If forcibly removed, the key and the mating shaft will be destroyed.

The process factors that affect the quality of high-strength fasteners include steel design, spheroidizing annealing, peeling and dephosphorization, drawing, cold heading, thread processing, heat treatment, etc., and sometimes the superposition of various factors.

The design of the existing shaft circlip is relatively simple, and the circlip is not fast enough to be fixed in the shaft groove. When the shaft circlip receives the repeated action of radial impact load, it is prone to loosening, which affects the use of the circlip.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: TA2 titanium nuts, large standard bolts, hexagonal thickened nuts, small flat washers and other products, we can provide you with suitable fastener solutions for you Program.
