Beneficial Effects

[0017] The protective box for electrical equipment according to the various embodiments of the present invention can play a reinforcing role and improve the anti-theft effect of electrical equipment compared with traditional electrical equipment protection boxes. It can also automatically increase the maintenance space when the electrical equipment is repaired, making it convenient for maintenance personnel to operate, and can appropriately adjust the protection effect according to the installation site.

[0018] In addition, when the professional pulls the pulling handle downward, the connecting plate drives the two pushing rods to move upward. At this time, the two pushing rods are separated from the two upper protective plates A and the two upper protective plates B. When the two pushing rods move upward, the two protective rods automatically move upward under the action of the two springs A. At this time, the two protective rods are separated from the two lower protective plates A and the two lower protective plates B, which is convenient for professionals to open the protective cover; because the sliding shaft, pulling handle and wire rope are located on the rear side of the shell, they play a better hiding role, which is not easy for thieves to find, and the anti-theft effect of electrical equipment is improved. When the professional releases the pulling handle, the two pushing rods can automatically move downward under the action of the counterweight bar, thereby realizing automatic reinforcement between the shell and the protective cover.

[0019] In addition, when the professional opens the protective cover, the mounting frame slowly moves forward under the action of the two springs B, which makes it convenient for the professional to repair the electrical equipment on the mounting frame, increases the maintenance space of the electrical equipment, and makes it more convenient for the maintenance personnel to operate. When the professional closes the protective cover, the mounting frame slowly moves backward under the action of the driving shaft, which is convenient for the professional to use.

[0020] In addition, when the present invention is used indoors, the installer can remove the pulling handle and then screw the connecting head onto the bottom of the sliding shaft. Because two limiting holes are penetrated through the pulling plate and a limiting column is fixedly installed on the bottom of the shell, and the diameter of the limiting column is the same as the two limiting holes, it is convenient for the installer to insert the limiting column into one of the limiting holes. At this time, the two pushing rods and the two upper protective plates A and the two upper protective plates B are always in a separated state, and the two protective rods and the two lower protective plates A and the two lower protective plates B are always in a separated state, so that when the present invention is used indoors, professionals no longer need to pull the sliding shaft when opening the protective cover, thereby reducing labor intensity. The present invention can appropriately adjust the protection effect according to the installation site, can prevent electrical equipment from being stolen when used outdoors, can reduce the labor intensity of professionals when used indoors, and is more convenient to use.
