Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model: An electrical engineering distribution box includes a distribution box main body 1, inside which a mounting bracket 7 is arranged through a mounting component, and an electrical component main body 10 (mainly composed of a circuit breaker, an air switch, a leakage protection switch, etc., which is a relatively mature technology and will not be elaborated here) is installed on the mounting bracket 7. A heat dissipation device (such as a heat dissipation fan, etc.) is also arranged inside it, and heat dissipation through holes are opened on the corresponding side walls, which can improve the air fluidity and facilitate ventilation and heat dissipation. The opening end of the distribution box main body 1 is installed with a box door 2 through a fixing component, and the contact part between the two can be sealed through a sealing device (such as the cooperation of a sealing gasket and a sealing groove, etc.). In order to be able to move the mounting bracket 7 out together when the box door 2 is opened, which is convenient for the maintenance or replacement operation of the electrical component main body 10, a reserved hole is also opened on the distribution box main body 1 to facilitate connection wiring, and a certain length of the cable is reserved, which does not affect the removal operation of the mounting bracket 7. This is a relatively mature technology and will not be elaborated here.

[0023] Please refer to Figures 1-5, in order to facilitate the installation and removal of the mounting frame 7, mounting plates 11 are welded equidistantly on the inner wall of the main body 1 of the distribution box. An installation chute 14 is formed inside the mounting plates 11. At both ends of the mounting frame 7, mounting sliders 16 are correspondingly welded, which are convenient for sliding in the installation chute 14. In order to facilitate sliding, balls 17 are rotatably arranged in the middle of the top and bottom ends of the mounting slider 16. A guide groove 15 for facilitating the rolling of the balls 17 is formed in the installation chute 14. In order to facilitate the removal of the mounting frame 7 together with the opening of the box door 2, a sleeve 12 of the connecting component is welded to the front end of the mounting frame 7. An adjustment cavity 8 is formed inside the sleeve 12. An adjustment plate 18 is slidably arranged inside the adjustment cavity 8. An extension rod 13 is welded to the end of the adjustment plate 18. The extension rod 13 slides out of the adjustment cavity 8 and extends to the outside and is welded and fixed to the box door 2, which is convenient for pulling the box door 2 to remove the mounting frame 7 together, facilitating maintenance or replacement operations.

[0024] Please refer to Figures 1-5 , in order to ensure the firmness of the box door 2 during use and avoid the rotation members 3 of the fixing components being welded to both side walls of the main body 1 of the distribution box. A fastening bolt 6 (composed of a screw rod and a nut) is rotatably arranged on the rotation member 3. Fixing blocks 4 are correspondingly welded to both side walls of the box door 2. A clamping groove 5 for facilitating the insertion of the screw rod is formed on the fixing blocks 4, which is convenient for subsequent fastening operations. In order to position and fix the extension rod 13 and the sleeve 12 when the box door 2 is opened, and prevent sliding, which may affect the maintenance operation, a limiting hole 22 of the limiting mechanism is formed on the circumferential surface of one of the sleeves 12 (the position is the sleeve 12 at the top, which can be left or right, and is opened according to the actual installation position of the main body 1 of the distribution box). A limiting member 19 is arranged inside the limiting hole 22. A sliding cavity 9 of the reset component is formed inside the adjustment plate 18. Moving plates 20 are symmetrically arranged in the sliding cavity 9 through springs 21. One end of each moving plate 20 away from each other is fixedly connected to the limiting member 19, and the limiting member 19 slides out of the sliding cavity 9.

[0025] Working principle: When the utility model is in use, the main body 10 of the electrical component is installed on the mounting bracket 7. Through the cooperation of the mounting chute 14 and the mounting slider 16, it can be assembled into the main body 1 of the distribution box. The ball 17 slides in the guiding groove 15 to assist the installation operation. Then, it is spliced with the box door 2 and the main body 1 of the distribution box. Under the action of the rotating member 3, the fastening bolt 6 is rotated into the card slot 5 of the fixing block 4, and tightening can complete the fastening operation without affecting normal use. When it is necessary to repair or replace the main body 10 of the internal electrical component, loosen the fastening bolt 6 and remove it from the card slot 5, and the fixation of the box door 2 can be lost. Pull the box door 2 outwards, the adjusting plate 18 slides in the adjusting cavity 8, and the extension rod 13 moves out of the sleeve 12. When it is pulled to the longest, the mounting bracket 7 can be moved. The mounting slider 16 slides in the mounting chute 14, and the whole can be moved out. When it is pulled to the longest, the limiting member 19 enters the limiting hole 22 to prevent the extension rod 13 from sliding, without affecting the repair or replacement operation. When assembling after the operation is completed, push the box door 2, and the mounting bracket 7 can be moved into the main body 1 of the distribution box. Then, by pressing the limiting member 19, the moving plate 20 can be made to slide in the sliding cavity 9, and the spring 21 contracts to store potential energy. When leaving the limiting member 19 and then pushing the box door 2 again, the splicing of the box door 2 and the main body 1 of the distribution box can be completed, and then fixation is completed through the fastening bolt 6.
