[0017] Furthermore, the remote surfaces of the two sets of limit plates are both provided with built-in handles.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides an electric meter box with a warning function, which has the following beneficial effects:

[0020] (1) The present invention provides a mobile box. When it is necessary to transport an electric meter box with a warning function, the operator first opens and closes the first sealing door by hand, and then uses two sets of installation screws to cooperate with four sets of installation nut threads. The operator rotates the four sets of installation nuts clockwise and counterclockwise by hand. The four sets of installation nuts respectively drive the four sets of iron pipes to move synchronously. When the gap length between the two sets of installation nuts on the same side reaches a suitable value, the two sets of mobile boxes are moved toward each other. When the four sets of magnet sleeves are adsorbed with the four sets of iron pipes, the two sets of limit plates are respectively in contact with the upper and lower parts of the box body. At this time, the suction force between the four sets of iron pipes and the four sets of magnet sleeves can be used to ensure that the two sets of mobile boxes are stably fixed inside the box body, and then the first sealing door is closed. The door is locked with a set of locks to lock the first sealed door. At this time, the size of the space occupied by the box body and the two sets of mobile boxes is reduced. When the electric meter box with a warning function is needed, the first sealed door is opened and closed again, and the two sets of mobile boxes are moved away from each other. When the four sets of magnet sleeves are in contact with the top and bottom surfaces of the two sets of positioning grooves respectively, the operator rotates the four sets of mounting nuts in reverse by hand. When the four sets of iron pipes are in contact with the four sets of magnet sleeves again, the two sets of mobile boxes are stably fixed. At this time, the two sets of mobile boxes are moved out of the box body. The interior of the box body and the two sets of mobile boxes provide space for the installation and use of the electric meter. By setting up the mobile boxes, more electric meter boxes can be stacked inside the transportation space, which facilitates the transportation of the electric meter boxes with a warning function.

[0021] (2) According to the above operation, after the two groups of mobile boxes are unfolded and installed, the electric meter can be installed inside the box body and the two groups of mobile boxes. When a fire occurs inside the box body and the two groups of mobile boxes, a large amount of heat will be generated. By utilizing the principle of heat transfer, the heat can be transferred to the two groups of heat-conducting rods through the two groups of heat-conducting columns. The heated two groups of heat-conducting rods can melt the two groups of paraffin orifice plates. When the two groups of paraffin orifice plates melt, the water on the upper part can fall into the interior of the two groups of liquid guide buckets. This part of the water then passes through the two groups of drip valves. The dripping water falls on the two groups of metal sheets, which will produce a knocking sound. The knocking sound is then discharged through the two groups of amplifying buckets. When the nearby operating workers hear the knocking, they can respond in time. The operating workers can pull out the four groups of sealing covers by hand and add or discharge the water inside the two groups of installation covers through the four groups of through holes. The installation cover has a prompt structure, which can prompt nearby operating workers whether a fire occurs inside the electric meter box without the help of an electric structure, thereby providing a guarantee for the safe use of the electric meter box with a warning function.

[0022] (3) The present invention provides a clearance groove and a roller. When the electric meter needs to be installed, the operator first moves a group of movable orifice plates on the same side by hand. This group of movable orifice plates can drive a group of serrated plates on the same side to move. Since the group of serrated plates on the same side are meshed with multiple groups of gears on the same side, the moving group of serrated plates on the same side can push the multiple groups of gears on the same side to rotate. The rotating multiple groups of gears on the same side can drive the multiple groups of rollers to rotate. When the multiple groups of rollers on the same side are rotated to a suitable position, the group of positioning screws on the same side cooperate with the threads of the positioning nuts on the same side. The operator can rotate the two groups of positioning nuts on the same side clockwise or counterclockwise by hand. When the two groups of positioning nuts on the same side are rotated to a suitable position, the operator can rotate the two groups of positioning nuts on the same side clockwise or counterclockwise by hand. When the positioning nut contacts with a group of movable orifice plates on the same side, a group of movable orifice plates on the same side, a group of serrated plates on the same side, multiple groups of gears on the same side and multiple groups of rotating shafts on the same side are stably fixed. A group of guide rods on the same side can ensure the stability of the movement of a group of movable orifice plates on the same side. The operation of the remaining groups of rollers can be obtained in the same way. After that, the electric meter can be moved into the box body and the interior of the two groups of movable boxes, and then the screws are used to penetrate the mounting holes of the electric meter, and then the screws are inserted clockwise into the interiors of multiple groups of threaded blind holes. Through the set give way grooves and rollers, the worn or blocked screw hole structure can be quickly replaced, which brings protection for the installation of the electric meter box and the electric meter with warning function.

[0047] Working principle:

[0048] When it is necessary to transport the electric meter box with a warning function, the operator first opens and closes the first sealing door 4 by hand, and then uses the two sets of mounting screws 14 to cooperate with the four sets of mounting nuts 16 threads. The operator rotates the four sets of mounting nuts 16 clockwise and counterclockwise by hand, and the four sets of mounting nuts 16 respectively drive the four sets of iron pipes 17 to move synchronously. When the gap length between the two sets of mounting nuts 16 on the same side reaches a suitable value, the two sets of mobile boxes 2 are moved toward each other. When the four sets of magnet sleeves 15 and the four sets of iron pipes 17 are adsorbed, the two sets of limit plates 3 are respectively in contact with the upper and lower parts of the box body 1. At this time, the suction force between the four sets of iron pipes 17 and the four sets of magnet sleeves 15 can be used to ensure that the two sets of mobile boxes 2 are stably fixed inside the box body 1, and then the first sealing door 4 is closed, and a set of locks 8 are used to lock it. The first sealing door 4 is held, and the size of the space occupied by the box body 1 and the two groups of mobile boxes 2 is reduced. When the electric meter box with a warning function is needed, the first sealing door 4 is opened and closed again, and the two groups of mobile boxes 2 are moved away from each other. When the four groups of magnet sleeves 15 are in contact with the top and bottom surfaces of the two groups of positioning grooves 13 respectively, the operator rotates the four groups of mounting nuts 16 in reverse by hand. When the four groups of iron pipes 17 are in contact with the four groups of magnet sleeves 15 again, the two groups of mobile boxes 2 are stably fixed. At this time, the two groups of mobile boxes 2 are moved out of the interior of the box body 1, and the interior of the box body 1 and the two groups of mobile boxes 2 provide space for the installation and use of electric meters. By setting the mobile box 2, it is ensured that more electric meter boxes are stacked inside the transportation space, which brings convenience to the transportation of the electric meter box with a warning function. At the same time, according to the above-mentioned operation It can be seen from the work that after the two groups of mobile boxes 2 are unfolded and installed, electric meters can be installed inside the box body 1 and the two groups of mobile boxes 2. When a fire occurs inside the box body 1 and the two groups of mobile boxes 2, a large amount of heat will be generated. Using the principle of heat transfer, the heat can be transferred to the two groups of heat-conducting rods 22 through the two groups of heat-conducting columns 21. The heated two groups of heat-conducting rods 22 can melt the two groups of paraffin orifice plates 19. When the two groups of paraffin orifice plates 19 melt, the water on the upper part can fall into the interior of the two groups of liquid guide buckets 36. This part of the water passes through the two groups of drip valves, and the dripping water falls on the two groups of metal sheets 24, which will produce a knocking sound. The knocking sound is then discharged through the two groups of amplifying buckets 27. When the nearby operating workers hear the knocking, they can respond in time. The operating workers manually pull out the four groups of sealing covers 26 , water inside the two sets of installation covers 9 can be added or discharged through the four sets of through holes 25. The installation cover 9 is provided with a prompt structure, which can remind nearby operators whether there is a fire inside the meter box without the help of an electric structure, thereby providing a guarantee for the safe use of the meter box with a warning function. At the same time, when it is necessary to install the meter, the operator first moves a group of movable orifice plates 32 on the same side by hand, and this group of movable orifice plates 32 can drive a group of sawtooth plates 34 on the same side to move. Since the group of sawtooth plates 34 on the same side are meshed with the multiple groups of gears 30 on the same side, the moving group of sawtooth plates 34 on the same side can push the multiple groups of gears 30 on the same side to rotate, and the rotating multiple groups of gears 30 on the same side can drive the multiple groups of rollers 11 to rotate. When the multiple groups of rollers 11 on the same side rotate to a suitable position,By using the threaded cooperation between a set of positioning screws 31 on the same side and the threaded cooperation between the positioning nuts 33 on the same side, the operator can rotate the two sets of positioning nuts 33 on the same side clockwise or counterclockwise by hand. When the two sets of positioning nuts 33 on the same side contact the set of movable orifice plates 32 on the same side, the set of movable orifice plates 32 on the same side, the set of serrated plates 34 on the same side, the multiple sets of gears 30 on the same side and the multiple sets of rotating shafts on the same side are stably fixed. The set of guide rods 35 on the same side can ensure the stability of the movement of the set of movable orifice plates 32 on the same side. The operation of the other sets of rollers 11 can be obtained in the same way. After that, the electric meter can be moved into the box body 1 and the two sets of movable boxes 2, and then the screws are used to penetrate the installation holes of the electric meter, and then the screws are inserted clockwise into the multiple sets of threaded blind holes 29. Through the set give way slots 10 and rollers 11, the worn or blocked screw hole structure can be quickly replaced, which brings protection to the installation of the electric meter box with warning function.
