To ensure the quality of installation, the hanging box must be fixed with built-in expansion bolts, and the bolt size must meet the requirements of safety and firmness and outdoor installation conditions;

[0003] In the prior art, as disclosed in announcement No. CN219286976U, a small electric energy meter box based on indoors is proposed. The technical scheme discloses a small electric energy meter box based on indoors, wherein the heat dissipation window embedding groove is slidably embedded with a heat dissipation window outer frame, the top surface of the heat dissipation window outer frame is provided with a drawing groove, and the inner surface of the heat dissipation window outer frame at one end is provided with a plurality of dust block fixing holes, and the dust block fixing rods are slidably embedded in the interior of the plurality of dust block fixing holes, and the surfaces of the plurality of dust block fixing rods are all equipped with dust block merging blocks, and one end of the heat dissipation window outer frame is embedded with a dust block merging block. In order to make it safer and more convenient to use, the heat dissipation window embedding groove, the bottom plate sliding groove, the heat dissipation window outer frame and the drawing groove are provided. Through the provision of the heat dissipation window embedding groove, the bottom plate sliding groove, the heat dissipation window outer frame and the drawing groove, the entire box body can ensure sufficient heat dissipation during daily use while providing sufficient dust protection for the inside of the box body, and the extremely easy-to-remove provision enables it to be removed and cleaned at any time after being used for a long time.

[0004] However, the existing electric energy meter box is generally fixed directly to the wall by bolts. After long-term use, the bolts connecting the electric energy meter box to the wall will become loose, which may cause the electric energy meter box to fall, which will not only cause certain damage to the electric energy meter box, but also pose certain safety hazards.

[0005] In order to solve the above problems, the present application proposes an electric energy metering box with a falling mechanism. Utility Model Content

[0006] The utility model aims to provide an electric energy meter box with a falling mechanism, which is mainly used to solve the problem that the existing electric energy meter box may fall when installed on the wall, thereby causing certain damage to the electric energy meter box and even posing a safety hazard.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] An electric energy metering box with a falling mechanism comprises a box body and a support plate, wherein a symmetrical L-shaped bracket is fixedly connected to the bottom of the support plate, damping rods are fixedly connected to the four corners of the top of the support plate, the upper end of the damping rod is fixedly connected to the buffer plate, the outer wall of the damping rod is sleeved with a spring, the upper end of the spring is fixedly connected to the buffer plate, the lower end is fixedly connected to the support plate, the upper end of the buffer plate is connected to the box body, the bottoms of both sides of the box body are fixedly connected to limiting components, and an alarm component is fixedly connected to the center of the top of the support plate.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When installing the electric energy meter box, first fix the box to the wall with expansion screws, then install the buffer plate to the bottom of the box, fix the box and the buffer plate with the limit assembly, and then fix the L-shaped bracket at the bottom of the support plate to the wall with expansion screws. When the expansion screws on the box and the wall are loose, the box will slide down and drive the buffer plate to move downward. When the buffer plate moves downward to a certain extent, it will trigger the alarm assembly, thereby reminding people to reinforce the box in time.

[0011] 2. Beneficial effect: By setting the box on the top of the buffer plate, a damping rod and a spring are arranged between the buffer plate and the support plate. When the box falls downward, the damping rod and the spring can cooperate to provide better buffering protection for the box. When the box drives the buffer plate to move downward to a certain extent, the alarm component will be triggered to remind people to reinforce the box in time, thereby effectively preventing the box from falling from the wall.

[0012] Preferably, the limiting assembly includes a fixing plate fixedly connected to the bottom of both sides of the box, and a clamping plate matching the fixing plate fixedly connected to both sides of the top of the buffer plate, the clamping plate is penetrated by bolts, and the fixing plate is provided with threaded holes matching the bolts. After the staff installs the box on the wall, the clamping plate on the buffer plate is aligned with the fixing plate on the box, and the buffer plate is pushed to install the buffer plate to the bottom of the box, and then the bolts are installed and tightened to make them threadedly connected with the threaded holes on the fixing plate. The advantage of such a setting is that it not only makes the connection between the box and the buffer plate more stable, but also makes the disassembly between the box and the buffer plate more convenient.

[0013] Preferably, the alarm assembly includes a buzzer fixedly connected at the center of the top of the support plate, a connecting rod fixedly connected at the center of the bottom of the buffer plate, and a contact matching the buzzer fixedly connected to the lower end of the connecting rod. When the collision screw on the box is loosened, the box will move downward under the action of gravity, thereby driving the buffer plate to move downward. When the buffer plate moves downward, it will drive the contact to move downward through the connecting rod, and the contact will contact the buzzer. The buzzer is a contact type setting, and the contact is made of copper and has good conductivity. Therefore, when the contact contacts the buzzer, the buzzer can be energized and make a buzzing sound, thereby reminding people that the electricity meter box is loose and the box needs to be reinforced in time, which can effectively prevent the electricity meter box from falling from the wall.

[0014] Preferably, there are multiple bolts on the pallet, and the bolts are evenly distributed on the pallet in a linear array. By setting the number of bolts on the pallet to multiple, after the staff installs the buffer plate to the bottom of the box, all the bolts need to be installed on the pallet. This can further improve the stability of the connection between the buffer plate and the box, thereby further preventing the electricity meter box from falling.

[0015] Preferably, the bolt is an embedded hexagonal setting, and the upper end surface of the bolt is not higher than the top of the card plate. After the bolt is installed, the upper end surface of the bolt is not higher than the top of the card plate, so that it will not bulge out and cause wear. The bolt is an embedded hexagonal setting, and the bolt with an embedded hexagonal setting can rotate better during installation, reducing the possibility of slip angle.

[0016] Preferably, the L-shaped brackets are fixedly connected with reinforcing ribs, and a triangle is formed between the reinforcing ribs and the L-shaped bracket through the reinforcing ribs arranged on the L-shaped bracket, so that the stability of the L-shaped bracket is higher, thereby providing a better supporting effect for the support plate.

[0017] Preferably, a rubber pad is fixedly connected to the top of the buffer plate, and the thickness of the rubber pad is not less than 1 cm. Since the rubber material has good cushioning and wear resistance, the rubber pad arranged on the buffer plate can effectively avoid hard contact between the box and the buffer plate, thereby providing better protection for the box.
