Referring to FIG. 1 , in order to lock the workpiece 3 ′ on the injection molded part 2 ′, the screw 5 ′ passes through the through hole on the workpiece 3 ′ and is screwed into the screw hole of the embedded nut 1 ′ to fix the workpiece 3 ′. The embedding between the embedded nut 1' and the injection-molded part 2' generally includes two ways. One is to heat the embedded nut 1' and then insert it into the injection-molded part 2' by hot pressing; the other is to insert the embedded nut into the injection-molded part 2'. 1' and the injection part 2' are integrally injection-molded. In order to ensure the bonding strength between the inner nut 1' and the injection molded part 2', knurling is provided on the outer peripheral surface of the inner nut 1'.
The nuts of some products must be installed on the outside, but due to the small internal space, when the indenter of the riveting machine cannot meet the strength requirements by methods such as riveting and budding, riveting and riveting are impossible. Rivets to be nailed. Applicable to the fixed field of each thickness plate and tube (0.5MM-6MM). Using pneumatic or manual riveting equipment, rivet once and it is easy to secure. Replacement of the existing welding nut to supplement the metal plate, the thin tube welding is easy to melt, and the welding nut is not smooth.
In the prior art, there are two ways to feed the screws of the locking screw machine, the air blowing type and the air suction type. The air suction type is suitable for relatively small screws. If the screw size is larger than M2, smaller than M5, and the length-diameter ratio is larger than 1.7, the air-blown screw machine can be selected.
screw with a gasket aims to provide a screw with a gasket that improves installation efficiency. The technical solution of the screw is that after the screw cap, the connecting rod and the screw rod are processed, the gasket with the installation through hole is processed. The installation through hole is drilled through the connecting rod, and then the end of the screw rod opposite to the connecting rod is processed to form a convex tooth structure by extrusion. At the same time, the outer diameter of the tooth peak of the convex tooth is larger than the inner diameter of the installation through hole, so that the gasket is not easy to be installed. Falling off, the step of manually wearing the gasket is reduced, that is, the workload of the staff is reduced, and the installation efficiency is relatively high. The flange increases the contact area between the screw cap and the gasket, and enhances the friction between the screw cap and the gasket, which can prevent the screw from loosening easily after being fastened and installed, thereby improving the connection stability of the screw. When installing the screw, the fixing part can be snapped into the fixing groove on the installation plane, so as to avoid the washer from rotating with the rotation of the screw when the screw is tightened, which is convenient for the tightening and installation of the screw.
In the installation of the external electrical components of the high-voltage electrical box, generally, the whole aluminum alloy profile with a T-slot is laid on the shell of the high-voltage electrical box, and then the upper nut is placed in the T-slot, and the bottom of the square nut is provided with a spring , When installing the electrical components, align the mounting holes with the screw holes of the square nut, then screw and tighten the screws to achieve the installation of electrical components. The biggest defect in the above installation process is that the alignment of the mounting hole and the screw hole is not very convenient, and the spring at the bottom of the square nut is easy to be missing. Once the spring is missing or damaged, the square nut cannot be effectively positioned in the T-slot. It makes the alignment of the mounting hole and the screw hole more difficult. Third, the above-mentioned connection and fixing method itself is not particularly ideal.
