Summary of information:We have more than ten years of production experience in the screw industry. The main products are: internal cross pocket...

Anchor bolts can be divided into fixed anchor bolts, movable anchor bolts, expansion anchor anchor bolts and adhesive anchor bolts. According to the different shapes, it is divided into: L-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welded embedded bolts, and bottom plate embedded bolts.

With the popularization of electrical equipment, the door cover that integrates the panel, the controller, the sealing and waterproof function and the appearance decoration has gradually been required for equipment matching. The head directly affects the appearance, and for kitchen equipment such as dishwashers, the fixing screws of the door cover are easily rusted in direct contact with the washing water, which urgently needs a door cover structure that is easy to disassemble but does not affect the appearance.

The equipment is tightened and fixed by screws during assembly. During high-speed operation, the equipment will generate high-frequency micro-vibration. This micro-vibration can easily lead to loosening of screws, resulting in weak connection of components and easy to cause safety accidents. Fastening is attached great importance. Many companies even directly weld the screw caps after using screws to fasten the components. However, this practice greatly hinders the subsequent maintenance and also seriously affects the maintenance and maintenance of the equipment; The emergence of tightening screws has attracted the attention and favor of enterprises; however, the self-tightening screws I use are mainly imported, and when the trade war begins, the shortage of this autonomous technology will severely limit my defense.

In addition, in the prior art, rivets are also used to riveted screws on metal plates. The rivets are nail-shaped objects with a cap at one end. In riveting, the riveted parts are connected by their own deformation or interference. When using rivets, it is necessary to set moderately sized positioning holes in the corresponding positions of the two metal plates, and the rivets directly penetrate into the positioning holes and then riveted. Because this riveting method does not require welding, it will leave a hole on the back of the metal plate. Therefore, in the prior art, the surfaces of the two metal plates after riveting are covered with a layer of smooth metal skin to cover the riveting marks, which will also increase the overall cost, including metal The cost of the skin and the increase in the manufacturing process, while the riveting process is limited, the connection between all metal plates cannot be universal.

[In a preferred example of Guangdong Yueluo Hardware Industry Co., Ltd., the cone includes a large diameter end and a small diameter end, the diameter of the large diameter end is the same as the diameter of the inner hole in the middle of the nail body, and the diameter of the small diameter end is Two-thirds of the diameter of the large diameter end.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: European standard T-nut, pressure riveting column SOS pressure riveting stud, set of 304 stainless steel screws, bolt cylindrical pins and other products, we can provide you with Provide the right fastener solution for you.
