[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 、 2 As shown in Figures 3, 4 and 5, the utility model provides a technical solution: an indoor distribution box that is easy to inspect and maintain, comprising: a fixed support portion, the fixed support portion has a fixed plate 1 connected to the wall, and the bottom of the fixed plate 1 is vertically welded with a bottom plate 3; the box body 4 is an N-shaped structure and the bottom opening is rotatably mounted on the outside of the bottom plate 3 through a rotating shaft, and the inner wall of the box body 4 is welded with a limiting rod 7; the locking portion is placed on the outside of the fixed plate 1, and the locking portion includes a support frame 10 fixed to the outside of the fixed plate 1, and the middle part of the support frame 10 is rotatably connected to a lock hook 13 interlocked with the limit rod 7. When the box body 4 is rotated upward to a state of cooperation with the fixed plate 1, the limit rod 7 pushes open the lock hook 13 and is stuck inside it.

[0024] It should be noted that, when the present invention is under maintenance, the lock hook 13 is pushed upwards, and the bottom of the box body 4 is rotated downwards along the rotating shafts on both sides of the bottom plate 3. Because there is a position difference between one side of the fixed plate 1 and the end of the box body 4, the corners of the box body 4 will not contact the wall when the box body 4 is rotated, so that the box body 4 is rotated to the bottom of the bottom plate 3. At this time, the electrical appliances inside the fixed plate 1 are exposed to the outside, so as to prevent the electrical appliances from being inconvenient to operate due to the small space when being repaired, and to prevent the box body 4 from blocking the light and detection tools, thereby affecting their maintenance.

[0025] See also Figure 1 、 2 As shown, a mounting frame 2 is fixed to one side of the fixed plate 1, a box door 5 is hinged on the outside of the box body 4, and L-shaped guide side plates 15 are fixed to one side of the fixed plate 1 and on both sides of the mounting frame 2 for supporting and guiding the box body 4.

[0026] It should be noted that the mounting bracket 2 of the present invention is used to fix and install electrical appliances. A plurality of mounting holes are installed in the middle of the mounting bracket 2 to facilitate cooperation with the fastening screws of the electrical appliances. When the box body 4 is rotated to cooperate with the fixing plate 1, the two sides of the inner wall of the box body 4 are in contact with the guide side plates 15. The guide side plates 15 can support the box body 4 from the inside and also guide the box body 4 to rotate to the specified position to cooperate with the fixing plate 1.

[0027] See also Figure 2As shown, a plurality of cable holes 14 are equidistantly provided in the middle of the bottom plate 3 , and a rubber strip 6 is fixedly connected to the side of the bottom plate 3 facing away from the fixed plate 1 , and the end of the rubber strip 6 is an arc-shaped structure.

[0028] It should be noted that the wiring hole 14 of the utility model can introduce the bottom of the wiring harness dynamic base plate 3 into the interior of the mounting frame 2. When the box body 4 is rotated to a position that cooperates with the fixed plate 1 and the box body 4 is closed, the rubber strip 6 is an elastic structure, which can be squeezed and matched with the box body 4, and the connection can be sealed to reduce the entry of dust.

[0029] See also Figure 2 、 4 As shown in Figure 5, the middle part of the limit rod 7 is fixedly connected to the limit ring 8, the end of the limit rod 7 is threadedly connected to the fastening nut 9, and the top of the support frame 10 is fixed with a bracket 11 for supporting the lock hook 13 and limiting the position of the limit rod 7. A reset spring 12 is fixed between the bottom of the lock hook 13 and the top of the support frame 10.

[0030] It should be noted that, when the box body 4 is rotated upward to cooperate with the fixed plate 1, the end of the lock hook 13 is a sloped structure, and the limit rod 7 hits the slope of the lock hook 13, pushing the lock hook 13 from one end, so that the lock hook 13 stretches the reset spring 12 upward. When the limit rod 7 and the hook tip of the lock hook 13 are misaligned, the reset spring 12 pulls the lock hook 13 to hook the limit rod 7, and under the obstruction of the bracket 11, the limit rod 7 is locked in the space formed by the lock hook 13, the support frame 10 and the bracket 11, and then the fastening nut 9 is rotated to tighten the support frame 10 by the fastening nut 9. Under the action of the friction force of the frosted surface on one side of the fastening nut 9, the limit rod 7 is prevented from being easily separated from the support frame 10.
