[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments. The present utility model provides the following embodiments.

[0025] Such as Figure 1As shown in the figure, it is a schematic structural diagram of an adjustable electric energy metering box according to a preferred embodiment of the present utility model. The adjustable electric energy metering box of this embodiment includes a C-shaped main frame 100. Side frames 101 are rotatably connected to both sides of the C-shaped main frame 100. Rotating door panels 102 are rotatably connected to the outer walls of the two side frames 101 close to the C-shaped main frame 100. An installation plate 103 is arranged inside the C-shaped main frame 100, and the electric meter is installed on the surface of the installation plate 103. In this embodiment, through the rotatably connected side frames 101, the side frames can be rotated and opened to both sides when overhauling the electric meter box, thereby increasing the space on both sides, facilitating the overhaul personnel to carry out the overhaul, and enabling the light in the corridor to shine into the interior of the electric meter box.

[0026] As Figure 2 shown, it is a schematic structural diagram of the C-shaped main frame in this embodiment. Elastic members 104 are fixedly connected to the inner wall of the C-shaped main frame 100 near the four corners. Each elastic member 104 is provided with a through circular groove, and a notch communicating with the circular groove is arranged on the outer wall of each elastic member 104. Plug-in circular rods 105 are fixedly connected to the outer walls on both sides of the installation plate 103, and the two plug-in circular rods 105 on both sides are respectively inserted into the interiors of the two limiting bosses 106 on both sides. In this embodiment, the electric meter is installed on the outer wall of the installation plate 103, and the connecting wire passes through the installation plate 103 and leaves enough length on the back of the installation plate 103. By bending one side of the plug-in circular rod 105 outward to slightly deform the limiting boss 106, one side of the plug-in circular rod 105 can be detached, and the other side of the plug-in circular rod 105 is still rotatably connected to the two limiting bosses 106 on the other side, so that the installation plate 103 can be rotated in different directions according to the actual overhaul situation, facilitating the overhaul of the back of the electric meter and enabling the electric meter to be overhauled in all aspects.

[0027] As Figure 2 shown, in order to prevent the plug-in circular rod 105 on the other side from falling off after one side of the plug-in circular rod 105 is bent out, in this embodiment, limiting bosses 106 are fixedly connected to the upper and lower ends of the two plug-in circular rods 105. In this embodiment, through the arrangement of the limiting bosses 106, the limiting bosses 106 can be firmly stuck inside the elastic members 104, making the fixing effect on the electric meter better.

[0028] As Figure 2-3 shown, plug-in holes 107 are arranged on both sides of the upper and lower horizontal plates of the C-shaped main frame 100 close to the vertical plates. Plug-in shafts 110 are fixedly connected to both the upper and lower sides of the side frames 101, and the plug-in shafts 110 are inserted into the plug-in holes 107. In this embodiment, through the rotational connection between the plug-in shafts 110 and the plug-in holes 107, the two side frames 101 can be rotated outward.

[0029] As Figure 3-4As shown in the figure, sliding grooves 108 are provided on the outer walls of the two side frames 101 close to the bottom of the C-shaped main frame 100. A sliding rod 109 is fixedly connected inside the sliding groove 108. A sliding block 112 is inserted into the sliding groove 108. The sliding block 112 is slidably connected to the outer wall of the sliding rod 109. Return springs 113 are sleeved on the outer walls of the two sliding rods 109 close to the rotating door panel 102. U-shaped frames 111 are fixedly connected to the outer walls of the opposite faces of the two sliding blocks 112. The openings of the two U-shaped frames 111 face each other. A rotating shaft 115 is rotatably connected inside the two U-shaped frames 111. Connecting rods 114 are fixedly connected to the outer walls of the two rotating shafts 115. The ends of the two connecting rods 114 away from the U-shaped frames 111 are inclined towards the center of the C-shaped main frame 100. A connecting member 116 is provided above the ends of the two connecting rods 114. The connecting member 116 is rotatably connected to the two connecting rods 114. In this embodiment, by pushing the connecting member 116 towards the vertical plate of the C-shaped main frame 100, the two connecting rods 114 are rotated through the rotating shaft 115, and thus the side frames 101 can be pushed outwards. The sliding block 112 slides inside the sliding groove 108 and compresses the return spring 113. After the maintenance is completed, the connecting member 116 is reset, and thus the two side frames 101 can be rotated back to seal the two sides of the C-shaped main frame 100.

[0030] It should be noted that the above-mentioned connecting rod 114, connecting member 116, U-shaped frame 111, sliding block 112, return spring 113 and sliding groove 108 are the unfolding components in this embodiment. The unfolding components include but are not limited to the connecting rod 114, connecting member 116, U-shaped frame 111, sliding block 112, return spring 113 and sliding groove 108. As long as the components that can make the two side frames 101 unfold outwards can be applied to this embodiment.

[0031] As Figure 1 and Figure 4 As shown in the figure, a sliding track 117 extending towards the vertical side of the C-shaped main frame 100 is fixedly connected to the bottom of the C-shaped main frame 100. The connecting member 116 is slidably connected to the inside of the sliding track 117. An adjusting screw 118 is rotatably connected to the inside of the sliding track 117. The adjusting screw 118 is threadedly connected to the connecting member 116. One end of the adjusting screw 118 away from the vertical side of the C-shaped main frame 100 passes through the sliding track 117, and a hexagonal head 119 is fixedly connected to the passing end of the adjusting screw 118. In this embodiment, a tool is clamped on the outer wall of the hexagonal head 119 and rotated, and thus the adjusting screw 118 can be driven to rotate, so that the connecting member 116 can slide inside the sliding track 117.

[0032] It should be noted that the above-mentioned adjusting screw 118 and hexagonal head 119 are the driving components in this embodiment. The driving components include, but are not limited to, the adjusting screw 118 and hexagonal head 119. As long as the component can make the connecting piece 116 slide along the inside of the sliding track 117, it can be applied to this embodiment.

[0033] The above content further elaborates on the present utility model in combination with specific implementation manners. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as falling within the protection scope determined by the claims submitted for the present utility model.
