Service HotlineGaskets are mechanical seals between two objects, usually used to prevent pressure, corrosion, and natural thermal expansion and contraction of pipes between two objects and leakage. Since machining the surface is not possible, irregularities can be filled with spacers. Gaskets are usually made from sheet materials such as pad paper, rubber, silicone rubber, metal, cork, felt, neoprene, rubber, fiberglass or plastic polymers such as Teflon. Gaskets for specific applications may contain asbestos. The existing gasket is easily deformed for a long time in use, and the gasket cannot play the role of making up the difference. In addition, during the use process of the gasket, the adhesion between the gasket and the nut or the mechanical surface becomes poor, resulting in a poor sealing effect.
structure for concealing installation screws, comprising a locking piece, a driving piece, a bottom plate, a blocking cover and a handle head, the lower ends of the two locking pieces are provided with positioning holes, and the locking pieces pass through the positioning holes and the locking piece positioning posts on the base The occlusal and fixed, the middle of the two locking pieces is provided with a protruding point, the movable groove of the driving piece corresponds to the protruding points of the three locking pieces for fixing, the riveting point holes and screw holes of the bottom plate and the riveting points of the base The position that matches the screw holes and is fixed by screws, the blocking cover is directly inserted into the bottom plate, and the blocking cover is fixed by the rotating drive piece, the handle head is inserted into the base, and the slot of the handle head moves to the locking piece at the locking piece Lock the handle.
The gasket is a part that is placed between the connector and the nut, and is generally a flat metal ring. Gaskets are used for mechanical seals between two objects, usually to prevent pressure, corrosion, and natural thermal expansion and contraction of pipes between two objects and leakage. Since machining the surface is not possible, irregularities can be filled with spacers. Gaskets are typically made from sheet materials such as backing paper, rubber, silicone rubber, metal, cork, felt, neoprene, rubber, fiberglass, or plastic polymers such as Teflon, application-specific gaskets May contain asbestos. Other uses are as spacers, springs (Belleville spacers, wave spacers), wear pads, pre-display devices, lock devices. Rubber gaskets are also used in faucets (valves) to cut off the flow of liquid or gas, and rubber or silicon gaskets are also used to reduce fan vibration. The function of ordinary gaskets is not good, the gaskets are easy to slip during the nut pressing process, the tightening effect is poor, the wear resistance of the gaskets is not good, and it has no anti-interference effect when used in electronic components.
Rivets are widely used in the fixing of product components, and the process of inserting rivets into products is currently mostly done by manpower. However, relying on manpower to insert rivets has low automation and low efficiency, which is not conducive to large-scale Production.
The shaft and gear of financial self-service equipment are often connected by elastic straight groove cylindrical pins. When repairing, the traditional disassembly method is to use the shaft and gear as components. After disassembling together, align the punch with the elastic pin by hand, and use a hammer to remove the elastic pin. Pin out. With this disassembly method, the human hand is easily injured, and the disassembly efficiency is low.
