The horizontal plates 8 on the two support plates 7 are opposite left and right. The top plate 2, the bottom plate 3 and the two side panels 6 are installed on the horizontal plates 8 on the two support plates 7 through sliding parts. At this time, the top plate 2, the bottom plate 3 and the two side panels 6 enclose a rectangular frame, and the three horizontal plates 8 on the support plates 7 are all located within the rectangular frame. One side of the rectangular frame is in contact with the back panel 4, and the door panel 5 is hinged on the side of one of the side panels 6 facing away from the back panel 4.

[0023] like Figure 1 and Figure 2 , remove the two support plates 7 from the back plate 4 through the mounting parts, and then remove the top plate 2, the bottom plate 3 and the two side plates 6 from the horizontal plate 8 through the sliding parts. At this time, the box body 1 formed by the top plate 2, the bottom plate 3, the back plate 4, the door plate 5 and the two side plates 6 can be disassembled, so that it is easy to move and use, and the disassembly is simple and the installation is convenient; like Figure 9 and Figure 10 One side of the back panel 4 is horizontally slidably connected to a first functional area 37 located below the box body 1 , and one side of the back panel 4 is vertically slidably connected to a second functional area 38 located at one side of the box body 1 . The second functional area 38 is vertically slidably connected to the first functional area 37 .

[0024] like Figure 2 and Figure 4 The top plate 2 and the bottom plate 3 are opposite to each other in vertical direction, and the two side plates 6 are opposite to each other in horizontal direction. The sliding member includes three first slide grooves 10 which are all arranged on the side of the two side plates 6 close to each other, and the three first slide grooves 10 are all connected to the side of the side plate 6 away from the back plate 4. The three first slide grooves 10 are all horizontally slidably connected with the first slide plate 12, and the three first slide plates 12 are respectively fixedly connected to the three horizontal plates 8 along the length direction of the horizontal plate 8. The bottom end of the top plate 2 is provided with two opposite second slide grooves 13, and the two second slide grooves 13 are all horizontally slidably connected with the second slide plate 14, and the two first slide grooves 13 are horizontally slidably connected with the second slide plate 14. The two slides 14 are respectively fixedly connected to the uppermost horizontal plates 8 on the two support plates 7, the two second slide grooves 13 are both connected to the side of the top plate 2 facing away from the back plate 4, two opposite third slide grooves 15 are provided at the top of the bottom plate 3, and the two third slide grooves 15 are both horizontally slidably connected with third slides 16, the two third slides 16 are respectively fixedly connected to the lowermost horizontal plates 8 on the two support plates 7, the two third slide grooves 15 are both connected to the side of the bottom plate 3 facing away from the back plate 4, and the two second slides 14 and the third slide 16 are both arranged along the length direction of the horizontal plate 8.

[0025] like Figure 2 and Figure 4 When the top plate 2, the bottom plate 3, the back plate 4, the door plate 5 and the two side plates 6 form the box body 1, the rectangular frame formed by the top plate 2, the bottom plate 3 and the two side plates 6 contacts the back plate 4, and the back plate 4 restricts the sliding of the top plate 2, the bottom plate 3 and the two side plates 6; like Figure 3 and Figure 4, when the two support plates 7 are removed from the back plate 4, the first sliding plate 12 is driven by the two side plates 6 to slide out from the first sliding groove 10 towards the direction close to the support plate 7. At this time, the two side plates 6 can be removed from the horizontal plate 8. Then, the second sliding plate 14 is driven by the top plate 2 to slide out from the second sliding groove 13 towards the direction close to the support plate 7. At this time, the top plate 2 can be removed from the horizontal plate 8. Then, the third sliding plate 16 is driven by the bottom plate 3 to slide out from the third sliding groove 15 towards the direction close to the support plate 7. At this time, the bottom plate 3 can be removed from the horizontal plate 8. The disassembly and assembly are simple.

[0026] As Figure 3 , the mounting member includes two mounting grooves 17 vertically arranged on one side of the back plate 4, and the two mounting grooves 17 are arranged oppositely. Both of the two mounting grooves 17 communicate with the top end of the back plate 4. The two support plates 7 are respectively vertically slidably connected in the two mounting grooves 17. The purpose of this setting is that when it is necessary to remove the support plate 7 from the back plate 4, only by pushing the bottom plate 3 or the two side plates 6 to drive the support plate 7 to move upward until the support plate 7 vertically slides out from the mounting groove 17. At this time, the support plate 7 can be removed from the back plate 4, and then the top plate 2, the bottom plate 3 and the two side plates 6 can be removed from the horizontal plate 8. The disassembly and assembly are simple.

[0027] As Figure 2 , between the two horizontal plates 8 on the left and right sides of one side of the two support plates 7, a hanging plate 19 for installing the electricity meter 18 is slidably connected through a moving member, and the number of the hanging plates 19 is the same as the number of the horizontal plates 8 on the support plate 7. The purpose of this setting is that by moving the hanging plate 19 to the end of the box body 1 far from the back plate 4 through the moving member, it is convenient to wire the electricity meter 18 on the hanging plate 19, and the situation that the box body 1 affects the wiring of the electricity meter 18 is reduced. The use is simple and convenient.

[0028] As Figure 2 , the moving member includes sliding plates 20 horizontally arranged on both sides of the hanging plate 19. Sliding grooves 21 for the sliding plates 20 to horizontally slide into are arranged on the horizontal plates 8 on both sides of the hanging plate 19. Limiting members for restricting the sliding of the sliding plates 20 in the sliding grooves 21 are arranged on the three horizontal plates 8 on one side of one of the support plates 7. The purpose of this setting is that by releasing the restriction of the limiting member on the sliding plate 20 and then pushing the hanging plate 19 away from the back plate 4, at this time, the hanging plate 19 will drive the sliding plate 20 to slide in the sliding groove 21. When moving to a suitable position, the wiring operation of the electricity meter 18 on the hanging plate 19 can be carried out. After the wiring is completed, push the hanging plate 19 close to the back plate 4. When moving to a suitable position, restrict the sliding plate 20 through the limiting member so that it cannot move. The use is simple and the wiring of the electricity meter 18 is convenient.

[0029] As Figure 5 and Figure 6 and Figure 7The limiting member includes a long strip groove 22 arranged at the bottom of the sliding groove 21 along the length direction of the sliding groove 21, and a limiting plate 23 is embedded in the long strip groove 22. A groove 24 is provided on the side of the horizontal plate 8 away from the back plate 4. A connecting groove 25 connected to the groove 24 is opened at the bottom of the long strip groove 22, and a rotating shaft 26 is rotatably connected in the connecting groove 25. A threaded groove 27 is provided at one end of the limiting plate 23 close to the rotating shaft 26, and a screw 28 is threadedly connected in the threaded groove 27. The screw 28 is coaxially fixedly connected to the rotating shaft 26. A power member for driving the rotating shaft 26 to rotate is provided on the horizontal plate 8.

[0030] like Figure 5 and Figure 6 and Figure 7 The rotating shaft 26 is driven to rotate by the power member, and the rotating shaft 26 drives the screw 28 to rotate. At this time, the cooperation between the screw 28 and the threaded groove 27 can push the limiting plate 23 to move away from or close to the bottom of the long groove 22. When the rotating shaft 26 rotates clockwise, the limiting plate 23 is away from the bottom of the long groove 22 until the limiting plate 23 and the sliding plate 20 are tightly pressed. At this time, the sliding plate 20 can be restricted and cannot move. When the rotating shaft 26 rotates counterclockwise, the limiting plate 23 is close to the bottom of the long groove 22 until the limiting plate 23 and the sliding plate 20 are separated. At this time, the restriction on the sliding plate 20 can be released, which is simple and convenient to use.

[0031] like Figure 7 The power part includes a first bevel gear 29 arranged at the end of the rotating shaft 26 away from the screw rod 28, the first bevel gear 29 is located in the groove 24, and the end of the horizontal plate 8 close to the notch of the groove 24 is fixedly connected to a fixing plate 30 located in the groove 24, and a rotation groove 31 is opened at the center of one side of the fixing plate 30, and a column 32 is rotatably connected in the rotation groove 31, one end of the column 32 extends to the outside of the rotation groove 31 and is provided with a second bevel gear 33 meshing with the first bevel gear 29, and the column 32 extends to the outside of the rotation groove 31 away from the second bevel gear 33 One end and a swivel ring 34 is provided. The purpose of this arrangement is that when it is necessary to drive the rotating shaft 26 to rotate, it is only necessary to rotate the swivel ring 34 to drive the column 32 to rotate. At this time, the column 32 drives the second bevel gear 33 to rotate, and the second bevel gear 33 will drive the rotating shaft 26 to rotate through the first bevel gear 29 meshing therewith, which is simple and convenient to use.

[0032] like Figure 2 and Figure 8 A wire threading groove 35 is provided at the lower side of each of the three suspension plates 19. The purpose of this arrangement is that the wire harness used to connect the electric energy meter 18 passes through the wire threading groove 35. At this time, the wire harness can be easily stored through the wire threading groove 35, and at the same time, confusion of the wire harness when connecting the electric energy meter 18 can be reduced, which is simple and convenient to use.

[0033] like Figure 8, on the side of the back plate 4 close to the hanging plate 19, three horizontal columns 36 are detachably connected, and the three horizontal columns 36 correspond to the three hanging plates 19 one by one. The three horizontal columns 36 are misaligned with the three wire troughs 35. The purpose of this setting is that through the horizontal columns 36, there is always a gap between the hanging plate 19 and the back plate 4. The wire harness is stored in the gap between the hanging plate 19 and the back plate 4. When the support plate 7 is removed from the back plate 4, first remove the three horizontal columns 36 from the back plate 4, which is simple and convenient to use.

[0034] Embodiment 2: An installation method according to the above Embodiment 1, detach two support plates 7 from the back plate 4 through the installation parts, and then detach the top plate 2, the bottom plate 3 and the two side plates 6 from the horizontal plate 8 through the sliding parts. At this time, the box body 1 formed by the top plate 2, the bottom plate 3, the back plate 4, the door panel 5 and the two side plates 6 can be disassembled.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
