However, although the existing screw can meet the function of connecting and tightening objects, its structure includes a head and a threaded rod connected with the head. Since it only has one threaded rod, it does not have a two-way connection function and cannot be satisfied with the Some special use requirements bring inconvenience to use.
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.
The function of the waterproof gasket is mainly to prevent the leakage of liquid or gaseous substances and the intrusion of external liquids, and has achieved the effect of sealing. Generally, the waterproof gasket is simply designed in the shape of a rubber ring plate.
It is suitable for plates of various thicknesses, with a minimum thickness of 0.8mm. When using, the tail number Z corresponding to size A must be determined according to the thickness of the plate and the specification of the nut. The user selects samples and orders according to the tail number in the table according to the thickness of the plate; Accurate control, processing according to the tolerance size of 0-+0.075mm, is punching, and the nut should generally be installed from the broken surface of the plate. The installation process is generally achieved through press riveting operations, and must not be impacted and knocked in.
