[0026] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that on the premise of no conflict, the following described embodiments or technical features can be combined arbitrarily to form new embodiments.

[0027] Please refer to Figures 1-5 , A power distribution cabinet in this embodiment includes a cabinet body 1. The cabinet body 1 is arranged in a "C" shape. On both sides of the cabinet body 1, cabinet door assemblies are symmetrically arranged to facilitate maintenance personnel to perform maintenance on the power distribution cabinet. On one side of each of the two cabinet door assemblies, a closing assembly is provided to facilitate the closing and fixing of the cabinet door assemblies. The cabinet door assembly includes a first cabinet door 201 rotatably installed on one side of the cabinet body 1. On one side of the first cabinet door 201, a second cabinet door 202 is rotatably installed. Inside the cabinet body 1, two support columns 4 are fixedly installed. On one side of each of the two support columns 4, it is in contact with the adjacent first cabinet door 201.

[0028] When the staff carries out the power distribution cabinet maintenance, only needs to open two second cabinet doors 202 normally, then moves the closing assembly on both sides, removes the locking effect of the closing assembly to the first cabinet door 201, can also open two first cabinet doors 201, so that the maintenance surface of the whole power distribution cabinet is increased from one surface to three surfaces, so as to facilitate the staff to carry out the maintenance, and when closing the power distribution cabinet, only needs to close the first cabinet door 201 first, the first cabinet door 201 is locked by the closing assembly automatically, then closes the second cabinet door 202, can complete the closing of the whole power distribution cabinet, so that the power distribution cabinet is set to be convenient to open and to carry out the maintenance inside.

[0029] The closing assembly comprises a fixed plate 301 fixedly installed on one side of the first cabinet door 201, a limiting plate 302 in the shape of a Chinese character "fang" is fixedly installed on one side of the support column 4, the limiting plate 302 is internally provided with a locking plate 303, a plurality of inclined tooth grooves 5 are formed on one side of the fixed plate 301 close to the locking plate 303, a clamping groove is formed on one side of the locking plate 303 close to the fixed plate 301, and one side of the locking plate 303 is arranged in an inclined manner.

[0030] When the tooth groove 5 of the fixed plate 301 abuts against the clamping groove of the locking plate 303, the fixed plate 301 is fixed by the locking plate 303, so that the fixed plate 301 cannot be moved, thereby fixing the position of the first cabinet door 201.

[0031] One side of the two limiting plates 302 is provided with a limiting column 6, one end of each limiting column 6 penetrates through the adjacent limiting plate 302 and the locking plate 303 and is fixedly installed, a pushing spring 7 is sleeved on each limiting column 6, both ends of each pushing spring 7 abut against the adjacent locking plate 303 and limiting plate 302 respectively, and the other end of each limiting column 6 is fixedly installed with a limiting plate.

[0032] The pushing spring 7 always pushes the locking plate 303, so that after the first cabinet door 201 is closed, the locking plate 303 can be kept in the state of abutting against the fixed plate 301, thereby avoiding that the movement of the fixed plate 301 can open the locking plate 303.

[0033] The implementation principle of the power engineering power distribution cabinet in the embodiment of the application is that when the staff needs to maintain the power distribution cabinet, only needs to normally open two second cabinet doors 202, then pulls the locking plate 303 on both sides by hand, separates the locking plate 303 from the fixed plate 301, so that the clamping groove of the locking plate 303 and the tooth groove 5 of the fixed plate 301 are separated, at this time the pushing spring 7 is in a compressed state, then rotates two first cabinet doors 201, and the fixed plate 301 is extracted from between the support column 4 and the locking plate 303 when the first cabinet door 201 is opened, so that the opening of the first cabinet door 201 is not limited.

[0034] In this way, after the first cabinet door 201 and the second cabinet door 202 are opened, the power distribution cabinet has three exposed surfaces, facilitating maintenance and repair of the power distribution cabinet from the front and the left and right sides.

[0035] When the power distribution cabinet needs to be closed after maintenance, only the first cabinet door 201 needs to be rotated to be attached to the support column 4. During the rotation, the fixed plate 301 contacts the inclined surface of the locking plate 303, thereby pushing the locking plate 303 away and into the space between the locking plate 303 and the support column 4. The spring 7 continuously pushes the locking plate 303, so that the clamping groove of the locking plate 303 is attached to the tooth groove 5 of the fixed plate 301. In this way, the fixed plate 301 cannot be pulled out from between the support column 4 and the locking plate 303 due to the clamping of the inclined tooth groove 5 and the clamping groove, so that the position of the fixed plate 301 is fixed, and the position of the first cabinet door 201 is fixed, and the first cabinet door 201 cannot be rotated and opened. Finally, closing the second cabinet door 202 can close the entire power distribution cabinet.

[0036] In this way, the power distribution cabinet can be maintained from multiple directions when needed, improving the maintenance efficiency of the staff, and avoiding the need for the staff to enter the interior of the power distribution cabinet for maintenance, thereby ensuring the safety of the staff.

[0037] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by those skilled in the art based on the present application are within the scope of protection of the present application.
