Service HotlineKnurled copper nuts are widely used in the following fields: notebook computer plastic casing, desktop computer plastic casing, GPS plastic casing, router plastic casing, mobile phone plastic casing, infinite communication facility plastic casing, home appliance plastic casing, automobile, electrical appliances, medical, electronics, etc. plastic shell.
The gasket is a part that is placed between the connector and the nut, and is generally a flat metal ring. GalwayGaskets 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. GalwayGaskets 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.
At present, in the field of building curtain wall, factory building support structure, shelf structure and other fields of steel structure connection, if closed profiles (such as rectangular steel pipes) are used as the connection structure, welding connection is generally used, and bolt connection cannot be realized. The reason why a bolted connection is not possible is that the profile is a closed structure and it is not possible to place the bolt at the connection location because the size of the bolt head is larger than the thread hole diameter on the profile. Welded connections affect the structural quality of outdoor projects, with poor corrosion resistance, reduced structural strength, and frequent fire accidents. However, the existing non-welded steel structure and the fastening connection of the bracket have complicated T-bolt structure, troublesome processing technology and high production cost.
Most of the existing screws use an integral metal structure, and there are still some problems, such as large weight, high cost of materials, wear resistance, hardness, rust resistance, corrosion resistance, high and low temperature resistance, brittleness, toughness, etc. Many occasions cannot meet the needs of production, and further improvements are needed to improve production efficiency, reduce costs, improve safety, and prolong the service life of screws.
Embedding of fasteners, especially screws. The main point of the structure is that it includes an annular base, one at the base and a plurality of cylindrical tubes on the base, and the cylindrical tubes and the cylindrical tubes on the base are connected by ribs. Cylindrical tubes are used as fixing holes and fastener pre-embedded holes respectively. The product is fixed on the formwork that needs to use screw points through the fixing holes. After the concrete is poured into the floor, the embedded screw parts are pre-embedded, and the floor has embedded screw holes for hanging the installation objects with screws. . Avoid future re-drilling damage to the wall and floor. Guangdong Yueluo Hardware Industry Co., Ltd. has a simple and scientific structure, easy pre-embedding, strong tensile strength and firmness.
