The existing spring pads are generally composed of longitudinal support springs, transverse connection springs, support springs, frames and frame clips. (Commonly known as string spring) is a slender and constant warp spring, used to connect the longitudinal support spring. The support spring is located at the edge of the spring pad to increase the shear resistance of the spring pad and the support strength of the frame. The surrounding frame connects the spring to the spring. up, fixed. The existing treatment method is to first heat-process the longitudinal support spring and the support spring made of 70# steel wire through the winding spring in a chemical solution, arrange them, and fix and connect them with a string spring, a frame and a clamping piece. Because the string spring and the frame have not been chemically heat treated, there is a large internal stress. Therefore, this treatment method has two disadvantages. One is that the processing efficiency of the heat treatment support spring is low. Larger, the spring is easily deformed and the service life is affected. In addition, the chemical solution after heat treatment is easy to cause environmental pollution
At present, the screws used by people are not provided with a device that does not loosen, especially in some key parts, if the screws are loosened, it will cause heavy losses. In order to overcome the current situation, there is no device on the screw to prevent the screw from loosening, which may cause heavy losses. Guangdong Yueluo Hardware Industry Co., Ltd. The inner part will not be loose, and it will save people the trouble of maintenance and reduce the hidden danger of accidents. The solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve its technical problems is to make a special screw and nut, set a stop groove on the screw, and then set a stop rod on the nut. After the screw is tightened , let the backstop rod be stuck in the backstop groove to prevent the screw from loosening. The beneficial effect of Guangdong Yueluo Hardware Industry Co., Ltd. is to ensure that the screws will not loosen during the service period, reducing the hidden danger of accidents and reducing the maintenance rate. Guangdong Yueluo Hardware Industry Co., Ltd. is further described below in conjunction with the accompanying drawings and embodiments
On the surface of the mounting hole on the connector, a 90-degree conical socket is machined, and the head of the flat machine screw is in the socket and is flush with the surface of the connector. Flat machine screws are also used in some occasions with semi-circle head flat machine screws, which are more beautiful and are used for places where a little protrusion is allowed on the surface. Screws play the role of connecting two or more objects and are an indispensable necessity in daily life or industrial manufacturing. There are countersunk head bolts (with grooves) and countersunk head bolts (with tenon).
Spring washers are often called spring washers in the screw industry. Its materials are stainless steel and carbon steel, and carbon steel is also iron. The commonly used spring washers are M3, M4, M5, M6, M8, M10, M12, M14, M16. These specifications are more commonly used. The national standard for spring washers is GB/T 94.1-87, which specifies standard spring washers with a size of 2-48mm. Reference standard GB94.4-85 Elastic Washer Technical Conditions Spring Washer
