Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: An electricity metering box, such as Figure 1 and Figure 2The enclosure includes a box 1, which includes a top plate 2, a bottom plate 3, a back plate 4, a door panel 5, and two side plates 6. Two opposing support plates 7 are mounted on one side of the back plate 4 via mounting components. Three horizontal plates 8 are horizontally arranged on the side of each support plate 7 away from the back plate 4, and the three horizontal plates 8 are spaced apart from top to bottom. The horizontal plates 8 on the two support plates 7 are opposite each other. The top plate 2, the bottom plate 3, and the two side plates 6 are mounted on the horizontal plates 8 on the two support plates 7 via sliding components. At this time, the top plate 2, the bottom plate 3, and the two side plates 6 form a rectangular frame, and the three horizontal plates 8 on the support plate 7 are all located within the rectangular frame. One side of the rectangular frame is in contact with the back plate 4. The door panel 5 is hinged to one of the side plates 6 on the side away from the back plate 4.

[0034] like Figure 1 and Figure 2 The two support plates 7 are removed from the back plate 4 by the mounting parts, and the top plate 2, bottom plate 3 and two side plates 6 are removed from the horizontal plate 8 by the sliding parts. At this time, the box 1 formed by the top plate 2, bottom plate 3, back plate 4, door plate 5 and two side plates 6 can be disassembled, which makes it easy to move and use. Disassembly is simple and installation is convenient.

[0035] like Figure 9 and Figure 10 The back panel 4 is horizontally slidably connected to a first functional area 37 located below the box body 1, and the back panel 4 is vertically slidably connected to a second functional area 38 located on one side of the box body 1. The second functional area 38 is vertically slidably connected to the first functional area 37.

[0036] like Figure 2 and Figure 4 The top plate 2 and the bottom plate 3 are vertically opposite each other, and the two side plates 6 are horizontally opposite each other. The sliding component includes three first sliding grooves 10, each disposed on one side of the two side plates 6 close to each other, and each of the three first sliding grooves 10 is connected to the side of the side plate 6 away from the back plate 4. Each of the three first sliding grooves 10 is horizontally slidably connected to a first sliding plate 12, and the three first sliding 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 opposing second sliding grooves 13, and each of the two second sliding grooves 13 is horizontally slidably connected to a second sliding plate 14. The two slide plates 14 are fixedly connected to the uppermost horizontal plates 8 on the two support plates 7 respectively. The two second slide grooves 13 are connected to the side of the top plate 2 away from the back plate 4. The top of the bottom plate 3 is provided with two opposing third slide grooves 15, and the two third slide grooves 15 are horizontally connected to the third slide plates 16. The two third slide plates 16 are fixedly connected to the lowermost horizontal plates 8 on the two support plates 7 respectively. The two third slide grooves 15 are connected to the side of the bottom plate 3 away from the back plate 4. The two second slide plates 14 and the third slide plates 16 are both set along the length direction of the horizontal plate 8.

[0037] like Figure 2 and Figure 4When the top plate 2, bottom plate 3, back plate 4, door plate 5, and two side plates 6 form the box 1, the rectangular frame formed by the top plate 2, bottom plate 3, and two side plates 6 contacts the back plate 4. At this time, the back plate 4 restricts the sliding of the top plate 2, bottom plate 3, and two side plates 6.

[0038] like Figure 3 and Figure 4 After the two support plates 7 are removed from the back plate 4, the two side plates 6 drive the first slide plate 12 to slide out from the first slide groove 10 towards the support plate 7. At this time, the two side plates 6 can be removed from the horizontal plate 8. Then, the top plate 2 drives the second slide plate 14 to slide out from the second slide groove 13 towards the support plate 7. At this time, the top plate 2 can be removed from the horizontal plate 8. Then, the bottom plate 3 drives the third slide plate 16 to slide out from the third slide groove 15 towards 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.

[0039] like Figure 3 The mounting components include two mounting slots 17 vertically arranged on one side of the back plate 4, with the two mounting slots 17 facing each other. Both mounting slots 17 are connected to the top of the back plate 4. Two support plates 7 are vertically slidably connected in the two mounting slots 17. The purpose of this arrangement is that when it is necessary to remove the support plates 7 from the back plate 4, it is only necessary to push the bottom plate 3 or the two side plates 6 to move the support plates 7 upward until the support plates 7 slide vertically out of the mounting slots 17. At this time, the support plates 7 can be removed from the back plate 4. 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.

[0040] like Figure 2 Two horizontal plates 8 on opposite sides of the two support plates 7 are slidably connected by a movable component to a suspension plate 19 for installing an energy meter 18. The number of suspension plates 19 is the same as the number of horizontal plates 8 on the support plates 7. The purpose of this setting is to slide the suspension plate 19 to the end of the housing 1 away from the back plate 4 by the movable component, which facilitates the wiring of the energy meter 18 on the suspension plate 19 and reduces the possibility of the housing 1 affecting the wiring of the energy meter 18. It is simple and convenient to use.

[0041] like Figure 2The moving part includes sliding plates 20 horizontally arranged on both sides of the suspension plate 19. Each horizontal plate 8 on both sides of the suspension plate 19 is provided with a sliding groove 21 for the sliding plate 20 to slide horizontally. Each of the three horizontal plates 8 on one side of one of the support plates 7 is provided with a limiting member to restrict the sliding plate 20 from sliding in the sliding groove 21. The purpose of this setting is to release the restriction of the sliding plate 20 by the limiting member and then push the suspension plate 19 away from the back plate 4. At this time, the suspension plate 19 will drive the sliding plate 20 to slide in the sliding groove 21. After moving to a suitable position, the electricity meter 18 on the suspension plate 19 can be wired. After the wiring is completed, push the suspension plate 19 closer to the back plate 4. After moving to a suitable position, the limiting member will restrict the sliding plate 20 so that it cannot move. It is simple to use and the electricity meter 18 is easy to wire.

[0042] like Figure 5 and Figure 6 and Figure 7 The limiting component includes an elongated groove 22 arranged along the length of the sliding groove 21 at the bottom of the sliding groove 21, and a limiting plate 23 embedded in the elongated 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 communicating with the groove 24 is opened at the bottom of the elongated groove 22, and a rotating shaft 26 is rotatably connected in the connecting groove 25. A threaded groove 27 is provided at the end of the limiting plate 23 near 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 component for driving the rotating shaft 26 to rotate is provided on the horizontal plate 8.

[0043] like Figure 5 and Figure 6 and Figure 7 The rotating shaft 26 is driven by a power component to rotate, which in turn drives the screw 28 to rotate. The screw 28, in conjunction with the threaded groove 27, pushes the limiting plate 23 to move away from or towards the bottom of the elongated groove 22. When the rotating shaft 26 rotates clockwise, the limiting plate 23 moves away from the bottom of the elongated groove 22 until it abuts against the sliding plate 20, thus restricting its movement. When the rotating shaft 26 rotates counterclockwise, the limiting plate 23 moves towards the bottom of the elongated groove 22 until it separates from the sliding plate 20, releasing the restriction on the sliding plate 20. This method is simple and convenient to use.

[0044] like Figure 7The power component includes a first bevel gear 29 located at the end of the rotating shaft 26 opposite to the screw 28. The first bevel gear 29 is located in the groove 24. A fixed plate 30 located in the groove 24 is fixedly connected to the end of the horizontal plate 8 near the opening of the groove 24. A rotating groove 31 is opened at the center of one side of the fixed plate 30. A column 32 is rotatably connected in the rotating groove 31. One end of the column 32 extends outside the rotating groove 31 and is provided with a second bevel gear 33 that meshes with the first bevel gear 29. The end of the column 32 opposite to the second bevel gear 33 extends outside the rotating groove 31 and is provided with a rotating ring 34. 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 rotating ring 34 to drive the column 32 to rotate. At this time, the column 32 drives the second bevel gear 33 to rotate. The second bevel gear 33 will then drive the rotating shaft 26 to rotate through the first bevel gear 29 that meshes with it. It is simple and convenient to use.

[0045] like Figure 2 and Figure 8 Each of the three suspension plates 19 has a wire channel 35 on one side below. The purpose of this setting is to allow the wire harness used to connect the energy meter 18 to pass through the wire channel 35. At this time, the wire harness can be easily stored through the wire channel 35, and the wire harness will be less likely to get confused when the energy meter 18 is wired. It is simple and convenient to use.

[0046] like Figure 8 Three horizontal posts 36 are detachably connected to the side of the back plate 4 near the suspension plate 19, and the three horizontal posts 36 correspond one-to-one with the three suspension plates 19. The three horizontal posts 36 are offset from the three wire grooves 35. The purpose of this setting is to ensure that there is always a gap between the suspension plate 19 and the back plate 4 through the horizontal posts 36, and the wire harness is stored in the gap between the suspension plate 19 and the back plate 4. When removing the support plate 7 from the back plate 4, the three horizontal posts 36 are removed from the back plate 4 first, which is simple and convenient to use.

[0047] Example 2: An installation method according to Example 1 above, the two support plates 7 are removed from the back plate 4 by the installation component, and then the top plate 2, bottom plate 3 and two side plates 6 are removed from the horizontal plate 8 by the sliding component. At this time, the box 1 formed by the top plate 2, bottom plate 3, back plate 4, door plate 5 and two side plates 6 can be disassembled.

[0048] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
