Service Hotlinescrew is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the mechanism of the object step by step. When using screws to fasten objects and parts, it is often necessary to use screws with spring washers and flat washers to lock and fix the relative position, so as to improve the stability of the fastening connection and make the screws less prone to loosening. However, in the prior art, the method of manually inserting the spring washer and the flat washer in sequence is generally used, which not only increases the workload of the staff, but also makes the installation efficiency relatively low. On the other hand, the traditional screw with a gasket only has the function of fixing, Without the function of sealing, it cannot be applied to special equipment such as oil tanks and airtight cabins. Therefore, it is necessary to design a screw that can reduce the workload and have its own sealing structure.
The technical solution adopted by Yueluo to solve its technical problems is: a cabinet with a hidden screw type installation structure. The cabinet includes corner fittings, frame profiles and plates. Connecting slot, the plate installation slot is U shaped, the plate installation slot on the frame profile can be set with one or two, the insertion slot is located on the inner side of the plate installation slot; the main body of the corner fitting is fixed in three directions. The plug connector, the outer side of the plug connector is provided with auxiliary plate installation grooves, and the auxiliary plate installation groove is provided with side baffles; the plug connectors on the corner fittings are correspondingly inserted into the plug connectors on the frame profile, and the cross section of the plug connector Consistent with the cross-sectional size of the corresponding insertion slot, the plate is inserted between the plate installation slots on the frame profile.
In the household and industry, when installing furniture, home appliances, electrical appliances, equipment and other objects, the objects are uneven or uneven due to the uneven bottom of the object, or because the placement surface or installation surface is uneven, or because the two surfaces are different and do not fit together. stable, produce vibration, shaking or sliding, affecting the use effect and service life. Sometimes two items need to be placed next to each other, but their surfaces cannot be in direct contact, otherwise the surfaces will be damaged. For these two cases, the common solution is to install gaskets. There are two types of gaskets: wedge and flat. The wedge-shaped gasket adjusts the actual thickness by adjusting the length of the insertion gap, but the contact surface and load-bearing surface of this method are small, and due to its wedge-shaped structure, the gasket may withdraw after being stressed for a long time. Flat gaskets are generally made from local materials, using waste paper, plastic, rubber, metal and other materials to form the required thickness by folding or stacking. Such gaskets are often not quickly assembled to the exact desired thickness, are not aesthetically pleasing, and are not reusable. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a product that can keep furniture, home appliances, equipment, electrical appliances and other objects horizontal, vertical or stable, prevent them from vibrating, shaking or sliding, and can provide appropriate thickness and beautiful appearance. gasket. The purpose of Yueluo is to realize a gasket that can be combined at will. The sheet 1 is provided with small holes 3 , and the connecting device 2 connects a plurality of sheets 1 together through the small holes 3 . The connecting device 2 is a rivet or a screw. The material of the sheet 1 can be plastic, metal, paper card or rubber. The gaskets provided by Yueluo can be combined at will. Multiple sheets are connected together by rivets or screws. By opening or closing the sheets, or dismantling the screws, the sheets are reassembled to obtain a combination of gaskets with different thicknesses and elasticity. The space between the installation object and the installation surface to keep the object horizontal, vertical or stable and prevent it from vibrating, shaking or sliding.
Nuts and bolts are one of the most widely used fasteners in modern mechanical structures. At present, the common metric bolts and nuts are generally trapezoidal in cross-section. The connection between the bolt and the nut is prone to loosening under severe vibration, or even falls off by itself, and the tightening force of the bolt and nut thread is mainly concentrated in the bolt thread and Between the teeth of the first few threads where the threads of the nut are in contact, resulting in loosening of the fastener and sliding pressure of the threads
[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: hexagonal thin nuts, sanitary fluoroplastic quick-install washers, flanged car nuts, corrosion-resistant screws and other products, we can provide you with products suitable for you fastener solutions.
