[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0038] Figure 1 It is a schematic diagram of the overall structure of the utility model, and combined with Figure 2As shown, the indoor concealed distribution box includes an outer box body 1, an inner box body 2 and a limit assembly. A convex edge 14 is fixed at the front edge of the outer box body 1, and a cover 3 is hinged on the front of the outer box body 1. The inner box body 2 is used to install various electrical equipment. The inner box body 2 is arranged inside the outer box body 1. Both side walls of the outer box body 1 and the inner box body 2 are provided with threading holes 4, and a movable structure is provided between the upper and lower walls of the inner box body 2 and the outer box body 1. The inner box body 2 can move in and out of the outer box body 1 through the movable structure. The limit assembly is arranged at the upper end of the inner box body 2, and the limit assembly is used to limit the position of the inner box body 2 after the inner box body 2 moves into the outer box body 1.

[0039] Among them, in the specific implementation of the present utility model, refer to Figure 5-Figure 6 As shown, there are four groups of mobile structures, which are distributed in pairs on the upper and lower surfaces of the inner box 2, and the mobile structures include:

[0040] A second groove 10, which is opened on the upper and lower surfaces inside the outer box body 1 along the depth direction of the outer box body 1;

[0041] A guide rod 11, wherein the guide rod 11 is connected to the second groove 10;

[0042] The guide block 12 is slidably connected to the outside of the guide rod 11 , and the guide block 12 is fixed to the inner box body 2 .

[0043] Through the above technical solution:

[0044] During use, when it is necessary to inspect the inner box 2, the staff can open the cover 3, first release the restriction of the limit assembly, and then pull the inner box 2 outward, and use the sliding of the guide block 12 on the outside of the guide rod 11 to move the inner box 2 partially or completely out of the outer box 1 according to the inspection needs, so that the staff does not need to lean against the wall or curl up in a corner for inspection, which is more convenient and quick, and greatly improves the inspection efficiency.

[0045] The structure of the second groove 10 can be described in the following two ways:

[0046] 1. The front end of the second groove 10 is not connected to the outside world. Figure 5 and Figure 6 As shown in the figure, the front end of the second groove 10 is blocked. When the guide block 12 slides outside the guide rod 11 to the front end blocking position of the second groove 10, this is the maximum outward movement space of the inner box 2 (that is, the inner box 2 is partially moved out of the outer box 1). This second groove 10 structural setting can prevent children from accidentally pulling and moving the inner box 2 out of the wall.

[0047] 2. The front end of the second groove 10 is connected to the outside (not shown). At this time, only the inner end of the guide rod 11 is connected to the outer box body 1, and the guide block 12 can slide out of the guide rod 11 to make the entire inner box body 2 completely separated from the outer box body 1. This second groove 10 structure is more convenient for maintenance personnel to operate.

[0048] In addition, it should be noted that sufficient length needs to be reserved between the cable connected into the inner box 2 and the outer box 1 to ensure that the cable has sufficient length to be pulled out when the inner box 2 is moved out.

[0049] See also Figure 1 and Figure 2 As shown, a gap is left between the outer wall of the inner box body 2 and the inner wall of the outer box body 1 to form a ventilation slot.

[0050] Specifically, the ventilation slots facilitate air circulation and are beneficial for heat dissipation.

[0051] See also Figure 2-Figure 4 As shown, there are two groups of limit assemblies, each group of limit assemblies includes:

[0052] A first groove 5, which is opened in the middle of the upper front end of the inner box body 2;

[0053] A through groove 8, which is formed on the inner wall of the first groove 5;

[0054] A positioning groove 9 is provided at the front side of the upper end of the inner wall of the outer box body 1;

[0055] The positioning rod 6 passes through the through groove 8 , one end of the positioning rod 6 located in the first groove 5 is connected to the pressing block 13 , and the other end of the positioning rod 6 away from the pressing block 13 is inserted and matched with the positioning groove 9 .

[0056] A spring 7 is provided outside the positioning rod 6 and between the pressing block 13 and the inner wall of the first groove 5 . The outer diameter of the spring 7 is greater than the inner diameter of the through groove 8 .

[0057] Through the above, before the inner box body 2 needs to be pulled out, the staff first presses the two pressing blocks 13 relative to each other to make the end of the positioning rod 6 disengage from the positioning groove 9, and then the inner box body 2 can be pulled out.

[0058] Before returning the inner box body 2 to its original position, the two pressing blocks 13 are also brought close to each other so that the spring 7 is in a stretched state. After the inner box body 2 reaches its original position, the pressing block 13 is released. During the process of the spring 7 returning to its original state, the end of the positioning rod 6 can be driven to be embedded in the positioning groove 9, thereby limiting the inner box body 2 and preventing it from being moved out at will.

[0059] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
