[0002] An energy meter box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy. It includes an energy meter, voltage and current transformers and their secondary circuits, an energy metering panel, cabinets, and boxes. It combines a combination transformer with measuring instruments and meters. A sealed box is attached to the oil tank side of the combination transformer, housing the measuring instruments and meters. The secondary outgoing wires of the combination transformer are connected to the wiring terminals of these instruments and meters in a prescribed manner.
[0003] However, some existing meter boxes need to be installed on the wall with expansion bolts when in use. During the installation process, the position of the meter box's own fixings needs to be adjusted after measuring the distance between the expansion bolts. However, the fixings are not convenient to adjust the position, which requires the staff to make multiple adjustments, reducing the installation efficiency of the meter box. In addition, the inaccurate position of the fixings will cause the meter box to be unevenly stressed, and it is easy to tilt to one side, affecting the installation effect.

Under the action of the threads on the surface of the two-way threaded rod 3, the two sleeves 4 can be moved in opposite directions at the same time when rotating, which not only facilitates the subsequent installation of the meter box, but also makes the force on both sides more uniform after installation, thereby improving the fixing effect of the meter box, one end of the two-way threaded rod 3 is fixedly connected to the bearing seat 12, and one side of the bearing seat 12 is fixedly connected to the inner wall of the mounting shell 2, and under this action, the two-way threaded rod 3 can be limited by the action of the bearing seat 12, so that the two-way threaded rod 3 can be fixed to the mounting shell 2. The screw rod 3 can be more stable when rotating, avoiding the two-way screw rod 3 being unstable when rotating and affecting the threaded connection between it and the sleeve 4. The other end of the two-way screw rod 3 is fixedly connected to a rotating seat 13, and one side of the rotating seat 13 penetrates the outer side of the mounting shell 2 and is rotatably connected to the inner wall of the penetration point. Under this action, it is convenient for the staff to use auxiliary tools to drive the two-way screw rod 3 to rotate under the action of the rotating seat 13, providing an effective force point for the staff to rotate the two-way screw rod 3, thereby making the two-way screw rod 3 easier to rotate. The surface of the sleeve 4 is fixedly connected to a guide block 14, and the surface of the guide block 14 is slidably connected to the inner wall of the mounting shell 2. Under this action, it can be guided when the sleeve 4 moves, thereby The sleeve 4 can be made more stable when moving, and the sleeve 4 can be prevented from rotating in place under the action of the two-way threaded rod 3 due to being unstable when moving, which effectively improves the stability of the sleeve 4 when moving. A positioning frame 5 is fixedly connected to one side of the sleeve 4, and a positioning hole 6 is opened on one side of the positioning frame 5. The positioning hole 6 cooperates with the bolt to facilitate the fixation of the metering box. Under the action of the two-way threaded rod 3, the position of the positioning hole 6 is conveniently adjusted, so that the metering box can be more convenient to install. The surface of the mounting shell 2 is provided with a scale line 11, and the scale line 11 is used in conjunction with the positioning frame 5. Under this action, the positioning frame 5 can cooperate with the scale line 11 when moving, which is convenient for the staff to recognize the position of the positioning frame 5 more accurately. , to further facilitate the convenience of the staff when installing the metering box, the surface of the positioning frame 5 is fixedly connected to the connecting block 7, and the surface of the connecting block 7 is slidably connected to the sliding shell 8. One side of the inner cavity of the sliding shell 8 is fixedly connected to a tension spring 9, and the other end of the tension spring 9 is fixedly connected to one side of the connecting block 7. Under this action, the tension spring 9 can cooperate with the sliding shell 8, and after the positioning frame 5 is fitted with the wall through the positioning hole 6, the sliding shell 8 can also be brought into contact with the wall under the action of the tension spring 9, thereby blocking rainwater when it rains, thereby reducing the contact between the bolts and rainwater, and reducing the situation where rainwater corrodes the bolts and affects the stability of the metering box. One side of the sliding shell 8 is fixedly connected to a connecting plate 10, and the connecting plate 10 is a flexible structure design.Under this action, when the sliding shell 8 squeezes the wall, the connecting plate 10 can be deformed under the action of pressure, so that the connecting plate 10 fits more closely to the wall, effectively reducing the gap between the connecting plate 10 and the wall, and improving the rainwater blocking effect. The inner cavity of the sliding shell 8 is fixedly connected to the guide rod 15, and the other end of the guide rod 15 passes through the other side of the connecting block 7 and is slidably connected to the inner wall of the penetration point. Under this action, the tension spring 9 can be limited in the process of stretching or rebounding with the cooperation of the guide rod 15, so that the tension spring 9 is more stable when in use, and the tension spring 9 is prevented from being significantly offset in use and affecting the squeezing effect on the connecting plate 10.
[0023] It is worth noting that the technical features such as the metering box body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.
[0024] Working principle: First, when the meter box needs to be installed, the staff first drives the expansion bolts into the wall, and then measures the distance between the expansion bolts, and then drives the two-way threaded rod 3 to rotate through the rotating seat 13. Under the action of the thread on the surface of the two-way threaded rod 3, the sleeve 4 will move, and the sleeve 4 will drive the positioning hole 6 to move through the positioning frame 5 during the movement. With the cooperation of the scale line 11, it is convenient for the staff to know the exact position of the positioning hole 6, and then move the positioning hole 6 to the appropriate position according to the cooperation of the scale line 11 and fix it through the cooperation of the positioning hole 6, so that it is convenient for the staff to install the meter box, and the position is more accurate. Under the cooperation of the expansion bolt and the positioning hole 6, the positioning frame 5 will gradually approach the wall, and then under the action of the tension spring 9, a reaction force will be applied to the sliding shell 8, so that the sliding shell 8 can make the connecting plate 10 fit on the wall, and under the action of the connecting plate 10 and the sliding shell 8, the expansion bolt is blocked, thereby improving the stability of the meter box.
