Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] A kind of flame-retardant environmentally friendly electric energy metering meter box, as shown in Figure Figures 1-5 It includes box 1, the box door 2 is rotatably installed in one side of box 1 by hinge, the heat dissipation port 7 is formed in one side of box 1, the baffle assembly for closing heat dissipation port 7 is fixedly connected to the inner wall of box 1, the baffle assembly includes shaft seat 8, the shaft seat 8 is fixedly connected to the inner wall of box 1, the rotating shaft 9 is rotatably installed in the shaft seat 8, the baffle 10 is fixedly connected to the side of rotating shaft 9, the sealing block 11 is fixedly connected to one side of baffle 10, the sealing block 11 is used to close heat dissipation port 7, the rectangular frame 12 is rotatably installed at the end of baffle 10, one end of rectangular frame 12 is slidably connected to the inner wall of box 1, the drive assembly for sliding one end of rectangular frame 12 is fixedly connected to the inner wall of box 1.

[0025] When there is no fire phenomenon in box 1, heat dissipation port 7 is in open state, which is convenient for internal heat dissipation of the present flame-retardant environmentally friendly electric energy metering meter box, box 1 and baffle assembly are made of resin-based composite material, which has flame-retardant environmental protection, box 1 is provided with smoke sensor (model MQ-2) for detecting whether it is on fire and controller for controlling the operation of drive assembly, the controller is prior art, the controller is connected with smoke sensor and drive assembly, the smoke sensor detects the smoke generated by fire and transmits the signal to the controller to control the operation of drive assembly.

[0026] By rotatably installing baffle 10 on the position corresponding to heat dissipation port 7 of the inner wall of box 1, when the fire occurs in box 1, the drive assembly pulls rectangular frame 12 to slide, so that rectangular frame 12 pulls baffle 10 to rotate, and sealing block 11 starts to close heat dissipation port 7, the number of heat dissipation ports 7 is the same as that of baffle assemblies, the drive assembly simultaneously drives multiple sets of baffle assemblies to operate to close multiple heat dissipation ports 7, the present meter box can timely close heat dissipation port 7 after internal fire, which has the ability to block the spread of flame and avoid the spread of flame in box 1 to the outside to cause fire.

[0027] As Figures 3-5 shown, the drive assembly includes an electric push rod 19, one end of which is fixedly connected to the inner wall of the box 1, and the output end of the electric push rod 19 is inserted and installed with a pull ring 20, the side of the pull ring 20 is fixedly connected with a pull rod 16, and the side of the pull rod 16 is fixedly connected with a sliding block 15 for pulling the rectangular frame 12 to slide.

[0028] The output end of the electric push rod 19 (model TA-01-30) pulls or pushes the pull rod 16, so that the pull rod 16 lifts or lowers in the inner wall of the box 1, and the pull rod 16 pulls the rectangular frame 12 through the sliding block 15, so that the rectangular frame 12 starts to slide from the end of the inner wall of the box 1. Since the rectangular frame 12, the baffle 10 and the inner wall of the box 1 form a triangle, one end of the rectangular frame 12 slides, one end rotates, the angle between the rectangular frame 12 and the baffle 10, and the angle between the baffle 10 and the inner wall of the box 1 are changed, so that the baffle 10 drives the sealing block 11 to approach until the sealing block 11 closes the heat dissipation port 7.

[0033] As shown in Figures 1-2 , the box door 2 is fixedly connected with an observation window 3 for observing the inside of the electric meter box, the observation window 3 is in a closed state, the back of the box 1 is fixedly connected with a mounting bracket 5, and the mounting bracket 5 is provided with a mounting hole 6.

[0034] The observation window 3 is convenient for observing the electric meter display and state inside the box 1, the mounting bracket 5 is inserted and installed with the wall surface through expansion bolts and the mounting hole 6, so as to hang the box 1 on the wall surface.

[0035] As shown in Figure 2 , the back of the box 1 is fixedly connected with a plurality of protrusions 4, and the plurality of protrusions 4 are used to form a space between the box 1 and the wall surface.

[0036] The convex 4 makes the back of the box 1 not adhere to the wall, and facilitates heat dissipation of the back of the box 1.

[0037] The working principle of the flame-retardant and environmentally-friendly electric energy metering meter box is as follows:

[0038] When the box 1 is on fire, the electric push rod 19 pulls down the pull rod 16, the pull rod 16 pulls one end of the rectangular frame 12 through the sliding block 15, the rectangular frame 12 slides, the rectangular frame 12 pulls the baffle 10 to rotate, the sealing block 11 starts to approach the heat dissipation opening 7, the heat dissipation opening 7 is closed, the driving assembly drives multiple sets of shielding assemblies to operate at the same time, and the multiple sets of heat dissipation openings 7 are closed.
