[0031] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0032] The present utility model provides a kind of electric energy metering box convenient for maintenance as Figure 1-6 shown, which includes a box body 1, two plate bodies 2 installed inside the box body 1, a mounting plate 3 arranged between the two plate bodies 2, and a plurality of electric energy meters 4 installed on the mounting plate 3;

[0033] A driving assembly is provided on the plate body 2 located below, and the driving assembly includes a makeshift groove 7 opened on the top of the lower plate body 2, a moving block 71 arranged inside the makeshift groove 7, a screw rod 72 transversely passing through the moving block 71, a first bevel gear 73 installed at the end of the screw rod 72, a second bevel gear 74 meshing with the first bevel gear 73, a rotating rod 75 connected to the bottom of the second bevel gear 74, and a push plate 76 arranged on the top of the moving block 71 and connected to the rear side of the mounting plate 3, which is used to drive the mounting plate 3 to translate between the two plate bodies 2 so that the electric energy meter 4 moves out of the box body 1.

[0034] In one embodiment, heat dissipation windows 5 are installed on both sides of the box body 1, so that the heat in the box body 1 can be dissipated in time, avoiding the temperature inside the box body 1 from being too high. The mounting plate 3 is located below each electric energy meter 4 and is provided with a plurality of threading holes 6 to facilitate the installation and use of the electric energy meter 4.

[0035] In one embodiment, a bearing is provided at the connection between the screw rod 72 and the plate body 2, the first bevel gear 73 is provided at an end of the screw rod 72 away from the mounting plate 3, and the plate body 2 is provided with a cavity 77 located at the first bevel gear 73 for accommodating the first bevel gear 73 and the second bevel gear 74. The bottom end of the rotating rod 75 passes through the plate body 2 and a bearing is provided at the connection with the plate body 2. A handle 78 is also installed at the bottom end of the rotating rod 75 to facilitate the staff to control the translation of the mounting plate 3.

[0036] In one embodiment, T-shaped blocks 8 are installed at left-right symmetrical positions on the top and bottom of the mounting plate 3, and the top of the T-shaped block 8 is connected to a limiting block 9. The adjacent side surfaces of the two plate bodies 2 are provided with a sliding groove 10 for the T-shaped block 8 to slide, and a limiting groove 11 adjacent to the sliding groove 10 for the limiting block 9 to slide, so that the mounting plate 3 has high stability when translated and will not tilt or get stuck.

[0037] In one embodiment, the front side surface of the T-shaped block 8 is flush with the front side surface of the mounting plate 3, and the length of the T-shaped block 8 is greater than the thickness of the mounting plate 3, so that the mounting plate 3 can be moved out to the outside of the box body 1, thereby making the electric energy meter 4 fully exposed to the field of vision of the staff, and the limit block 9 is arranged on an end of the T-shaped block 8 away from the mounting plate 3, the slide groove 10 extends to the front side surface of the plate body 2, and the slide groove 10 is adapted to the T-shaped block 8, and the length of the limit groove 11 is less than the length of the slide groove 10, so as to limit the translation stroke of the mounting plate 3 and prevent the mounting plate 3 from being separated from the box body 1.

[0038] The specific implementation mode is as follows: when the utility model is in use, multiple electric energy meters 4 are installed on the mounting plate 3, and the wiring harness is passed through the wire threading hole 6 to the rear side or the left and right sides of the mounting plate 3, and a sufficient length is reserved so that the wiring harness will not be broken when the mounting plate 3 moves;

[0039] Specifically, when the electric energy meter 4 in the box body 1 needs to be repaired, the staff opens the box door and rotates the handle 78 at the bottom of the lower plate body 2 in the forward direction, driving the rotating rod 75 to rotate in the forward direction, thereby rotating the second bevel gear 74, and further driving the first bevel gear 73 to rotate. At this time, the screw rod 72 will rotate about its own axis, forcing the moving block 71 to slide toward the cabinet door, that is, forward along the yielding groove 7, further causing the push plate 76 to slide forward, thereby causing the mounting plate 3 to slide forward along the plate body 2. At this time, multiple electric energy meters 4 slide forward together, and as the mounting plate 3 continues to move forward, they can eventually slide out to the outside of the box body 1, fully exposed to the staff's sight, avoiding the obstruction of the box body 1, so that the staff can quickly complete the maintenance;

[0040] When the push plate 76 pushes the mounting plate 3, the T-shaped block 8 will move forward along the slide groove 10, thereby ensuring the stability of the mounting plate 3 when moving, and the T-shaped block 8 is located at the rear side of the mounting plate 3, so that the mounting plate 3 can slide out from between the two plate bodies 2 and slide to the outside of the box body 1, and the limit block 9 limits the sliding stroke of the mounting plate 3 to prevent the mounting plate 3 from separating from the plate body 2 and the box body 1. The design of the T-shaped block 8 and the slide groove 10 makes the mounting plate 3 have high stability when it is outside the box body 1, so that it is convenient for the staff to perform maintenance. At the same time, by rotating the handle 78 in the opposite direction, the mounting plate 3 can drive the electric energy meter 4 to reset, so that the box body 1 and the electric energy meter 4 can continue to be put into use;

[0041] This embodiment specifically solves the problem in the prior art that the current electric energy meter 4 is usually directly fixed in the box body 1 of the electric energy meter box. When the electric energy meter 4 needs to be repaired, the operation is inconvenient due to the limited size of the box body 1, and there are many components inside the box body 1, and the staff's line of sight is easily obstructed, which greatly reduces the staff's work efficiency and urgently needs to be improved.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
