DETAILED DESCRIPTION

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Embodiment 1: An insulating protective cover for an electric energy meter box, such as Figure 1-Figure 5 As shown, it includes a box body 1, a door panel 2, a heat dissipation fan 3, a guide rail 4, a mounting plate 5, a mounting seat 51, a first spring 52, a bidirectional screw rod 6, a connecting block 7, a wire barrel 8 and a baffle 9. Ventilation holes are arranged on the left and right sides of the box body 1. The front side of the box body 1 is rotatably connected with the left and right door panels 2. The right door panel 2 is provided with a transparent observation window. The rear side of the box body 1 is fixedly connected with the heat dissipation fan 3. The left and right parts of the inner rear side of the box body 1 are fixedly connected with the guide rail 4. The left and right guide rails 4 are slidably connected with the mounting holes symmetrically arranged in the upper and lower directions. A mounting plate 5 is provided, and four mounting seats 51 are slidably connected to the mounting plate 5. A first spring 52 is connected between the mounting seat 51 and the adjacent mounting plate 5. A bidirectional screw rod 6 is rotatably connected to the middle position of the rear side of the box body 1. A handle is provided in the middle of the bidirectional screw rod 6. The upper and lower parts of the bidirectional screw rod 6 are both connected to connecting blocks 7 by threads. The connecting block 7 is connected to the adjacent mounting plate 5. A left-right symmetrical wire barrel 8 is slidably connected to the lower side of the box body 1. A baffle plate 9 is fixedly connected to the wire barrel 8, and the baffle plate 9 is in contact with the lower side of the box body 1.

[0033] When using the device, the staff controls the door panel 2 to rotate forward and open, and then installs the electricity meter box on the mounting plate 5 through the mounting seat 51. During installation, the bidirectional screw rod 6 can be controlled to rotate to drive the connecting block 7 to move toward or away from each other, thereby driving the mounting plate 5 to slide up and down on the guide rail 4 to adjust the position, thereby adapting to electricity meter boxes of different sizes and models. After installation, the staff passes the wires through the wire barrel 8 to connect the electricity meter box. At the same time, the wire barrel 8 can slide left and right on the lower side of the box body 1 to adapt to the wiring position of electricity meter boxes of different sizes and models, and the baffle 9 can prevent dust from entering the box body 1. After the wiring is completed, the staff controls the door panel 2 to rotate backward and close. During the use of this device, the cooling fan 3 and the vent can ventilate and dissipate heat inside the box body 1, so that it can be adjusted to adapt to electricity meter boxes of different sizes.

[0034] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 7 As shown, it also includes a wire clamping mechanism, which includes a rotating clamping plate 10, a fixed clamping plate 101, a first torsion spring 11 and a closing component. The rotating clamping plate 10 is rotatably connected to the lower side of the baffle 9, and the fixed clamping plate 101 is fixedly connected to the lower side of the baffle 9. The fixed clamping plate 101 and the rotating clamping plate 10 are fitted together to block the lower side of the wire tube 8, and three wiring ports are provided at the fitting point of the fixed clamping plate 101 and the rotating clamping plate 10. A first torsion spring 11 is connected between the rotating clamping plate 10 and the baffle 9, and a closing component for blocking dust is provided on the rotating clamping plate 10 and the fixed clamping plate 101.

[0035] like Figure 6 As shown, the closing assembly includes a fixed rod 12, a closing plate 13 and a second torsion spring 14. The lower sides of the rotating clamp 10 and the fixed clamp 101 are fixedly connected to the fixed rod 12. The closing plate 13 is rotatably connected to the fixed rod 12. The closing plates 13 respectively block an adjacent wiring port. A second torsion spring 14 is connected between the closing plate 13 and the adjacent fixed rod 12.

[0036] By setting up a wire clamping mechanism, the wires connected to the electric energy meter box can be fixed to prevent the wires from being pulled loose. The specific operation is as follows: the staff controls the rotating clamp 10 to rotate forward and open, the first torsion spring 11 is deformed, and then the wires are passed through the wiring port between the rotating clamp 10 and the fixed clamp 101. After passing through, the staff loosens the rotating clamp 10, and under the action of the first torsion spring 11 resetting, the rotating clamp 10 rotates backward and resets to cooperate with the fixed clamp 101 to fix the wires to prevent the wires from being pulled loose. When only one wire needs to pass through the wire tube 8, the staff fixes the wire at the wiring port between the rotating clamp 10 and the fixed clamp 101, and the other wiring ports are blocked by the closing plate 13 for dust prevention. When multiple wires need to be connected, under the action of the second torsion spring 14, the closing plate 13 can also be freely rotated to open and close, so that other wires can be connected to the side wiring ports.

[0037] like Figure 2 and Figure 8 As shown, it also includes a buffer mechanism for buffering the opening and closing of the door panel 2, the buffer mechanism includes a rotating plate 15, a sliding rod 16, a second spring 17 and a limit assembly, the left and right sides of the box body 1 are rotatably connected with the rotating plates 15 which are symmetrical up and down, the rotating plate 15 is slidably connected with the sliding rod 16, the sliding rod 16 is rotatably connected to the adjacent door panel 2, the second spring 17 is connected between the sliding rod 16 and the adjacent rotating plate 15, and a limit assembly is provided on the rotating plate 15 and the box body 1, and the limit assembly is used to limit the rotation angle of the rotating plate 15.

[0038] like Figure 2 and Figure 8 As shown, the limiting assembly includes a connecting rod 18 and a blocking block 19. The connecting rod 18 is fixedly connected between the two vertically symmetrical rotating plates 15. The vertically symmetrical blocking blocks 19 are fixedly connected to the left and right sides of the box body 1. The blocking blocks 19 are in contact with the adjacent connecting rods 18.

[0039] By providing a buffer mechanism, the opening and closing of the door panel 2 can be buffered to prevent the door panel 2 from being damaged by excessive opening and closing force, or causing damage to the electric energy meter box. The specific operation is as follows: the door panel 2 rotates forward to drive the sliding rod 16 and the rotating plate 15 to rotate forward. While the sliding rod 16 rotates forward, it will slide outward in the rotating plate 15, and the second spring 17 will be deformed. The elastic force of the second spring 17 controls the door panel 2 to open smoothly to prevent the door panel 2 from being damaged. When the door panel 2 is rotated backward to close, the sliding rod 16 and the rotating plate 15 will also rotate backward. Under the action of the second spring 17 resetting, the sliding rod 16 slides back into the rotating plate 15 to reset, and at the same time, the connecting rod 18 is blocked by the blocking block 19, thereby limiting the distance that the rotating plate 15 rotates backward to prevent the door panel 2 from hitting the electric energy meter box with excessive force when closing.

[0040] like Figure 1 , Fig. 9 and Fig.10 As shown, a protection mechanism for buffering protection of the electric energy metering box is also included, the protection mechanism includes a telescopic frame 20, a cross bar 21, a plug plate 22 and a third spring 23, the telescopic frame 20 is slidably connected to the upper and lower sides of the box body 1, the telescopic frame 20 is L-shaped, and the vertical end of the telescopic frame 20 is a telescopic structure, the door panel 2 is squeezed and matched with the telescopic frame 20, and the rear part of the telescopic frame 20 is fixedly connected to a left-right symmetrical cross bar 21, four plug plates 22 are slidably connected to the mounting plate 5, the plug plates 22 are stuck on the rear side of the adjacent mounting seat 51, the upper part of the plug plates 22 is an inclined structure, the plug plates 22 are squeezed and matched with the adjacent cross bars 21, and the plug plates 22 and the adjacent mounting plate 5 are connected with a third spring 23.

[0041] When the door panel 2 no longer presses the telescopic frame 20 forward, the plug plate 22 is reset and re-locked to the mounting seat 51 under the action of the third spring 23.

[0042] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
