[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following describes an embodiment of the wall-mounted power metering box of this utility model with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, the wall-mounted electricity metering box of this utility model embodiment may include: a box body 1, two sets of symmetrically arranged fixing mechanisms 2 and a door body 4.

[0024] Two through holes 11 are symmetrically opened on the box body 1.

[0025] The fixing mechanism 2 includes a rod 21, an expansion assembly 22, and a connecting assembly 23.

[0026] The expansion component 22 and the connecting component 23 are respectively connected to the rod 21. The rod 21 and the expansion component 22 pass through the through hole 11. One end of the expansion component 22 and the connecting component 23 are both located inside the box 1. The connecting component 23 abuts against the corner of the box 1.

[0027] Understandably, the connecting component 23 abuts against the corner of the housing 1, which can distribute the force between the housing 1 and the connecting component 23 to the side wall and the top and bottom walls of the housing 1, thereby ensuring the fixing effect and extending the service life of the metering box.

[0028] The bottom wall of the box 1 has a wire hole 3.

[0029] Understandably, wire hole 3 is used for the wires used by the metering box to pass through.

[0030] The door 4 is pivotally connected to the box 1, and a viewing window 41 is provided on the door 4.

[0031] It should be noted that relevant technicians can observe the status and data of the electricity meter in the metering box through the viewing window 41 on the door 4, which is convenient to use.

[0032] Specifically, when installing this metering box, the relevant technicians first used a hand drill to drill two mounting holes at a preset position on the wall, and then inserted the rod 21 into the mounting holes.

[0033] After the two rods 21 are fixed, the relevant technicians take the measuring box and insert the through hole 11 on the box 1 through the two rods 21.

[0034] The expansion component 22 is connected to the rod 21, which can fix the rod 21 in the mounting hole. Then the connecting component 23 is connected to the rod 21, so that the connecting component 23 abuts against the corner of the box 1, so that the box 1 is evenly stressed, thereby extending the service life of the box 1.

[0035] Finally, the relevant technicians installed the electricity meter in the metering box and connected the wires to it.

[0036] In one embodiment of this utility model, such as Figure 2 As shown, the expansion assembly 22 includes a sleeve 221, a guide portion 223, and a drive nut 224.

[0037] Among them, the sleeve 221 is sleeved on the outside of the rod 21, and multiple openings 222 are opened at one end of the sleeve 221. The guide part 223 is set at one end of the rod 21, and the diameter of the guide part 223 is larger than the diameter of the sleeve 221. The drive nut 224 is threadedly connected to the rod 21, and the drive nut 224 abuts against the other end of the sleeve 221. The drive nut 224 is located inside the housing 1.

[0038] Specifically, when installing the expansion assembly 22, firstly, the sleeve 221 is fitted onto the outside of the rod 21, and then the drive nut 224 is placed on the threaded part of the rod 21. The drive nut 224 is rotated using a tool, and the drive nut 224 pushes the sleeve 221 to move. Under the action of the guide part 223, one end of the sleeve 221 opens and interacts with the mounting hole, thereby fixing the rod 21 inside the mounting hole.

[0039] In one embodiment of this utility model, such as Figure 2 As shown, the connecting assembly 23 includes a ring 231, two hinge rods 232, two right-angle supports 233, and a knob 234.

[0040] Among them, the ring body 231 is slidably disposed on the outside of the rod body 21, one end of the two hinge rods 232 is pivotally connected to the ring body 231, and the other end of the two hinge rods 232 is pivotally connected to the corresponding right-angle support 233, and the two right-angle supports 233 respectively abut against the corner of the box body 1.

[0041] The angle between the hinge rod 232 and the rod body 21 is 45°.

[0042] It should be noted that the angle between the hinge rod 232 and the rod body 21 is 45°, which allows the right-angle support 233 to exert the same force on the side wall, top wall or bottom wall of the box body 1.

[0043] The knob 234 is threadedly connected to the rod 21, and the knob 234 is in contact with the ring 231.

[0044] Specifically, when installing the connecting component 23 and the rod 21, first, the ring 231 is fitted onto the outside of the rod 21, and the ring 231 is pushed so that the right-angle support 233 is close to the corner of the box 1. Then, the knob 234 is rotated so that the knob 234 is connected to the thread on the rod 21. The knob 234 pushes the ring 231 to move. Under the connection of the hinge rod 232, the right-angle support 233 abuts against the corner of the box 1.

[0045] In one embodiment of this utility model, such as Figure 4 As shown, pads 51 are provided at the four corners of the box 1, and rubber pads 52 are installed on the pads 51.

[0046] Understandably, setting the foot 51 allows for a certain distance between the box 1 and the wall, preventing subsequent dampness from the wall from affecting the electrical components inside the metering box.

[0047] The rubber pad 52 can provide a reverse force, making the metering box stable during installation.

[0048] In one embodiment of this utility model, such as Figure 4 As shown, a rubber protective ring 61 is provided on the wire hole 3.

[0049] Understandably, the rubber protective ring 61 is designed to prevent the wire from contacting the inner wall of the wire hole 3, thus protecting the wire.

[0050] In one embodiment of this utility model, such as Figures 1-2 As shown, a rubber plug 71 is fitted on the outside of the sleeve 221. One end of the rubber plug 71 has a tapered structure and is inserted into the through hole 11.

[0051] During the process of the drive nut 224 pushing the sleeve 221 to move, the sleeve 221 drives the rubber plug 71 into the interior of the through hole 11, thereby sealing the through hole 11 and preventing external water from entering the interior of the box 1 through the through hole 11, thus ensuring the normal operation of the metering box.

[0052] In summary, the wall-mounted electricity metering box of this utility model utilizes the connecting components in the fixing mechanism to abut against the corner of the box body, so that the box body is evenly stressed, thereby extending the service life of the box body.
