Design and application analysis of door hinge of anti-leakage control box
With the progress of science and technology and the improvement of people's living standards, people's demand for security has gradually increased. In the field of power equipment, how to ensure personal safety and prevent leakage accidents is one of the most important issues. As an important part connecting the box body and the box cover of the control box, the door hinge plays an indispensable role.
I. Preface
At present, the traditional iron or copper hinges are widely used as the door opening and closing devices for the common low-voltage power distribution cabinets/power cabinets with metal shells on the market. However, this kind of material itself does not have insulation performance and is easy to get wet and rust, which leads to the danger of electric shock. For this reason, we put forward a kind of "anti-leakage control box door hinge" which is made of new materials and has excellent heat conduction and anti-corrosion functions, in order to meet the growing safety requirements and solve the shortcomings of traditional products.
Second, the design principle and structural characteristics
This product mainly consists of the following parts:
1. Shell: ABS engineering plastic injection molding, high strength and good corrosion resistance;
2. Inner ring: PVC soft glue is used to wrap the steel ball bearing, and the lubrication degree is increased and the friction force is reduced through special process treatment;
3. Hinge shaft: made of stainless steel, the surface is smooth and burr-free after fine grinding;
4. Locking screw group: all of them are fixed by SUS304 stainless steel screws, which can be disassembled repeatedly without affecting the sealing effect;
Third, the advantage analysis:
(1) Safety: Because the whole hinge is filled with PVC soft rubber layer, there will be no current leakage even in humid environment;
(2) Durability: the outer frame is made of high-strength ABS plastic, which can bear large impact and is not easy to be damaged; At the same time, it contains precision ball bearings to ensure smooth operation for a long time without abnormal sound;
(3) Convenient installation and maintenance: each part is assembled separately for easy replacement and repair in the future. In addition, it is equipped with special tools for quick positioning and debugging;
Fourth, the application scenario
Suitable for all kinds of high and low voltage distribution cabinets, switch cabinets, control panels and other electrical equipment as door opening and closing mechanisms;
V. Summary
To sum up, the "anti-leakage control box door hinge" not only has excellent physical and mechanical properties, but also has good chemical stability and electrical isolation characteristics, which can keep stable operation under various harsh working conditions, effectively avoiding accidents and bringing users a more comfortable and comfortable experience!
