[0020] In order to better understand the technical solution of the present invention, the following is a detailed description through specific embodiments:

[0021] See also Figures 1 to 6 , the utility model provides an electrical box for a shield door or a safety door.

[0022] See also Figure 1 The box body 4 is fixed to the top box 1, which is located on top of the security door body 2. The top of the box body 4 is equipped with hanging ears on both sides, and the top box 1 is equipped with hooks that dock with the hanging ears. In addition to being connected to the platform side cover, the box body is also hung inside the top box, increasing the overall connection strength. A shock-absorbing pad is installed at the connection between the box body 4 and the top box 1 to reduce vibration caused by the door opening and closing, ensuring that the electronic equipment inside the box is protected from vibration and improving reliability.

[0023] See also Figure 2 and Figure 3 The platform side cover 3 is closed from the front of the box body 4.

[0024] Furthermore, an embedding groove is provided on the inner side of the platform side cover 3, and the front end of the box body 4 is snapped into the embedding groove, thereby limiting the installation position of the box body 4 and ensuring convenient and reliable installation. A compression sealing strip 5 is provided at the connection between the box body 4 and the platform side cover 3.

[0025] Specifically, the box body is made of aluminum, steel, or plastic. The platform side cover is made of aluminum alloy, steel, glass, or stainless steel. The compression seal is made of EPDM rubber, silicone rubber, or foam.

[0026] See also Figure 4 The two top corners of the platform side cover 3 are connected to the top box pivot and can be flipped open or closed, making it easy to inspect and repair the equipment in the box.

[0027] See also Figure 5 A lock 32 is installed at the connection between the lower edge 31 of the platform-side cover 3 and the top box. This lock connects the platform-side cover to the top box structure, preventing unauthorized personnel from opening the platform-side cover at will, ensuring safety. The lock also restricts the platform-side cover from turning over and applies force to the cover, compressing it against the rubber strip on the electrical box, achieving a good sealing and protective effect.

[0028] See also Figure 6 A cable entry 41 is provided on the side of the housing 4, through which external cables connect to the circuit components within the housing. Cable entry 41 can be a gland or other suitable cable entry product. Connecting the electrical components directly through the cable entry, rather than directly connecting the cables, further enhances the protective effect.

[0029] This utility model secures the electrical box, housing the electrical components, within the top box structure, enclosing the box from the front with a platform-side cover. Cables entering and exiting the box connect to the terminal blocks and other components within the box via cable entry components installed on the box. The platform-side cover locks securely to the top box structure with a lock at its lower end, simultaneously compressing the cover against the rubber strips on the box to provide effective protection. For maintenance, the platform-side cover can be opened by unlocking the lock to access and maintain or replace electrical components and wiring.

[0030] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
