DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-6 The utility model provides a technical solution: a low-voltage power distribution cabinet, comprising a first cabinet 1 and a second cabinet 2, the first cabinet 1 is detachably installed on both sides of the second cabinet 2, and sealing blocks 4 are fixedly installed on the top and bottom of the second cabinet 2;

[0022] A sealing groove 5 is provided on the adjacent surface of the first cabinet 1 and the second cabinet 2, a connecting rod 6 is detachably installed at the inner corner of the adjacent surface of the first cabinet 1 and the second cabinet 2, and a socket matching the connecting rod 6 is provided at the inner corners of the top and bottom of the second cabinet 2, and positioning bolts 7 are respectively installed at the outer inner corners of the connection between the first cabinet 1 and the second cabinet 2;

[0023] Specifically, connecting rods 6 are installed through threads at the inner corners of the adjacent surfaces of the two groups of first cabinets 1 and second cabinets 2, so that the adjacent surfaces of the two groups of first cabinets 1 and second cabinets 2 can be quickly connected through the connecting rods 6 and the sockets, and can be penetrated and positioned through the positioning bolts 7 outside the cabinets.

[0024] Specifically, the adjacent surfaces of the two groups of first cabinets 1 and second cabinets 2 can be sealed and connected through the sealing blocks 4 and the sealing grooves 5, and the adjacent surfaces of the first cabinet 1 and the second cabinet 2 can be plugged into the corresponding sockets through the connecting rods 6, and can be fixed by the positioning bolts 7 on the outside of the cabinets. In this way, when the low-voltage distribution cabinet is assembled and used on site, the first cabinet 1 and the second cabinet 2 can be integrally formed by processing and can be directly transported to the site for on-site assembly. Compared with the existing low-voltage distribution cabinets, the cabinets formed by processing can be stacked as a whole for easy transportation. At the same time, when assembled on site, multiple groups of single-grid cabinets are assembled into a low-voltage distribution cabinet, which is convenient for quick assembly and use on site.

[0025] Among them, the first cabinet body 1 and the second cabinet body 2 are respectively hinged with a first movable door 11 and a second movable door 21 on the front side, and the first movable door 11 and the second movable door 21 are fixedly installed with a handle 3 on the front side. The inner side of the handle 3 on the front side of the movable door can be installed with an anti-theft lock sealed between the cabinets, and the anti-theft lock on the handle 3 can be locked with the cabinet. The technical solution for installing the anti-theft lock is a prior art and will not be elaborated here.

[0026] Among them, the adjacent surfaces of the first cabinet 1 and the second cabinet 2 are sealed and connected through the sealing block 4 and the sealing groove 5, and the inner corners of the adjacent surfaces of the first cabinet 1 and the second cabinet 2 are plugged into each other through the connecting rod 6 and the socket. The inner corners of the adjacent surfaces of the two groups of the first cabinet 1 and the second cabinet 2 are equipped with connecting rods 6 through threads, so that the adjacent surfaces of the two groups of the first cabinet 1 and the second cabinet 2 can be quickly plugged into each other through the connecting rods 6 and the sockets.

[0027] Among them, locking mechanisms 8 are respectively installed at the inner corners of the front faces of the first movable door 11 and the second movable door 21, and movable grooves 81 are respectively opened at the inner corners of the front faces of the first movable door 11 and the second movable door 21. The locking mechanism 8 includes a pin shaft 82 that slides in the inner wall of the movable groove 81, and a positioning spring 83 is installed between the pin shaft 82 and the inner wall of the movable groove 81. Pin holes matching the pin shaft 82 are respectively opened at the inner corners of the top and bottom of the second movable door 21, and the pin shaft 82 on the second movable door 21 is inserted into the corresponding pin holes. In the embodiment, after the first cabinet body 1 and the second cabinet body 2 are assembled and positioned, the protrusion of the pin shaft 82 in the locking mechanism 8 can be moved on the movable door of the adjacent cabinet body, so that the pin shaft 82 squeezes the positioning spring 83 on the protrusion, so that the pin shaft 82 is inserted and positioned with the pin hole on the adjacent movable door. In this way, after the first cabinet body 1 and the second cabinet body 2 are assembled into a low-voltage distribution cabinet, the movable doors on the front of the cabinet body can also be assembled and positioned by the locking mechanism 8 to form movable doors on the same plane, so that after multiple groups of movable doors are assembled and positioned, they can be used in conjunction with the low-voltage distribution cabinet as a whole.

[0028] Working principle: When in use, first separate the two sets of first cabinets 1 from the second cabinets 2, and then assemble four sets of connecting rods 6 at the inner corners of the adjacent surfaces of the two sets of first cabinets 1 and the second cabinets 2 through threads;

[0029] Then, the adjacent surfaces of the two sets of first cabinets 1 and second cabinets 2 can be sealed and connected through the sealing block 4 and the sealing groove 5, and the adjacent surfaces of the first cabinet 1 and the second cabinet 2 can be correspondingly plugged into the jack through the connecting rod 6, and the positioning bolts 7 are used to penetrate and position the cabinet outside. In this way, when the low-voltage power distribution cabinet is assembled and used on site, the first cabinet 1 and the second cabinet 2 can be directly transported to the site after being integrally formed through processing, and assembled on site;

[0030] Finally, after the first cabinet 1 and the second cabinet 2 are assembled and positioned, the protrusion of the pin shaft 82 in the locking mechanism 8 can be moved on the movable door of the adjacent cabinet, so that the pin shaft 82 squeezes the positioning spring 83 on the protrusion, so that the pin shaft 82 is inserted and positioned with the pin hole on the adjacent movable door. In this way, after the first cabinet 1 and the second cabinet 2 are assembled into a low-voltage distribution cabinet, the movable doors on the front of the cabinets can also be assembled and positioned by the locking mechanism 8 to form movable doors on the same plane, so that after multiple groups of movable doors are assembled and positioned, they can be used in conjunction with the low-voltage distribution cabinet as a whole.
