The circlip is also called a retaining ring or a retaining ring. It is a kind of fastener and is installed in the shaft groove or hole groove of the machine and equipment to prevent the axial movement of the parts on the shaft or hole. The circlip includes an arc-shaped elastic bending portion and a circlip protrusion at the end of the elastic curved portion, and the circlip protrusion is provided with a small hole for matching with needle-nose pliers or circlip pliers. This part is a commonly used part on the equipment. Once the assembly is not in place, it will affect the overall performance of the equipment and cause safety hazards. At present, the most common assembly method is to manually clamp and deform the circlip with circlip pliers or needle-nose pliers, put the circlip into the annular groove of the inner hole of the end cover, and then release the needle-nose pliers or circlip pliers. . The assembly of the circlip is very troublesome, labor-intensive, and has low assembly efficiency. Once mass production is required, this process often becomes a bottleneck restricting production.

Alloy Steel Nuts Hexagon Nuts (GB6170/DIN934, GB6175), Flange Nuts (GB6177/DIN6923) Round Nuts (GB812), Small Round Nuts (GB810), American Square Nuts, American Hex Nuts (NI/MEB18.2.2), Heavy Duty Nuts (Metric, US). Specifications: 5/16-4. Nut Specifications Nut specification table is to unify all kinds of nuts in detail, and use the table to subdivide some specifications of nuts. There are many types of nuts, and there are nuts of different materials. Each type of nut has different specifications, and each type of screw also has its mechanical properties and functions.

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.

shaft retaining ring installation tool and an installation method thereof relate to an assembly tool and an installation method thereof, comprising a pressing cylinder and a taper sleeve. The maximum diameter of the tapered end is slightly smaller than the inner diameter of the circular straight hole of the pressing cylinder, and the lower end of the tapered sleeve has a positioning structure matched with the shaft of the shaft retaining ring to be installed. The method includes the following: place the taper sleeve on one end of the shaft where the shaft retaining ring is to be installed and position it well, then place the shaft retaining ring on the tapered end of the taper sleeve, and finally press down the pressure cylinder to make the shaft Use the retaining ring to slide down the conical surface of the taper sleeve to the shaft to be installed with the retaining ring for the shaft, and finally get stuck in the groove of the shaft. Yueluo does not need to open the retaining ring for the shaft, which reduces the operation force and labor intensity. The operation method is simple, the structure is simple and reliable, the cost is low, and it is easy to popularize and use.
