Description

Technical Field

[0001] This utility model relates to the technical field of electricity metering boxes, specifically to an electricity metering box. Background Technology

[0002] An electricity metering box is a device for measuring electrical energy. After an electricity meter is installed inside the box, the electricity energy is converted into an electrical signal and displayed on the dials of an ammeter and a voltmeter. This allows users to understand various electrical energy indicators such as current, voltage, and power in real time.

[0003] Traditional electricity metering boxes have certain limitations in their structural design: the connection between the box body and the door is not equipped with a damping device, which directly results in the lack of buffer adjustment capability during the opening and closing of the door. It is impossible to achieve stable hovering or adjustment at multiple angles according to actual operation needs. During operation, it often requires additional fixing or faces the problem of the door closing by itself, which affects the ease of use to some extent. Summary of the Invention

[0004] The purpose of this utility model is to provide an electricity metering box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electricity metering box, comprising a box body, wherein a first chamber and a second chamber are respectively formed on the front surface of the box body, and a first door and a second door are respectively fixedly connected to the front surface of the box body in the first chamber and the second chamber via hinge assemblies, respectively, and a mounting position is formed on the surface of the box body at a position opposite to the hinge assembly, and a rotating block is fixedly connected to the first door and the second door at a position opposite to the hinge assembly, and a rotating cavity is formed in the middle of the surface of the rotating block, the hinge assembly comprising a mounting base and a pin, the rear end of the mounting base being installed in the mounting position by fasteners, the front end of the mounting base being rotatably connected to the rotating cavity, a first rotating hole being formed on the front surface of the mounting base, and a second rotating hole being formed on the surface of the rotating block at a position opposite to the first rotating hole, and the first rotating hole and the second rotating hole being connected by a pin.

[0006] Preferably, the inner wall of the first rotating hole is provided with a plurality of limiting grooves evenly distributed, and the front and rear ends of the pin surface are provided with snap-fit ​​grooves symmetrically distributed, and a limiting strip that is movably engaged with the limiting groove is snapped into the snap-fit ​​groove.

[0007] Preferably, an installation plate is installed at the top of the first chamber, and a plurality of shorting connector assemblies are installed on the surface of the installation plate, with an electricity meter connected to each shorting connector assembly.

[0008] Preferably, the shorting connector assembly includes a support base and a socket. The support base is fixedly installed on the surface of the mounting plate, and the socket is rotatably connected to the lower part of the support base surface. An electricity meter is connected to the socket.

[0009] Preferably, a guide rail frame is fixedly installed in the first chamber below the mounting plate, and a miniature circuit breaker is snapped onto the guide rail frame at a position opposite to the shorting connector assembly, and the miniature circuit breaker and the shorting connector assembly are connected by a wire.

[0011] Beneficial effects

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model innovatively improves the connection structure between the box body and the door body. By setting a hinge assembly consisting of a mounting base, a pin, and a rotating block, and cooperating with the limiting groove in the first rotating hole and the limiting strip on the pin, a reliable damping adjustment structure is formed. When the first and second doors are opened and closed, the movement of the limiting strip in the limiting groove provides stable buffering and limiting for the rotation of the doors, achieving stable suspension of the doors at multiple angles. This design completely changes the situation where traditional metering box doors lack buffering and cannot be stably suspended. It allows the door to remain stable at the required angle without additional fixing, greatly improving the convenience of operation and avoiding interference caused by the door closing itself.

[0014] 2. This utility model brings significant advantages through the application of the short-circuit connector assembly. The short-circuit connector assembly consists of a support base and a rotatable socket. The electricity meter is quickly connected via the socket. Compared with the traditional wire connection method, it simplifies the installation and replacement process of the electricity meter. Operators do not need to perform complicated wiring operations, which significantly improves the efficiency of electricity meter installation and subsequent maintenance and replacement, and reduces the difficulty of operation.

[0015] 3. This utility model plays a crucial role in the design of the guide rail frame and the miniature circuit breaker. The miniature circuit breaker is mounted on the guide rail frame via a snap-fit ​​mechanism and connected to the shorting connector assembly via wires. This modular installation structure not only makes the circuit layout more organized and orderly but also facilitates the quick installation, disassembly, and replacement of the miniature circuit breaker. Simultaneously, the maintenance port and cover on the first door allow operators to perform routine inspections and maintenance on the miniature circuit breaker without opening the entire first door, further enhancing the convenience of maintenance.

[0029] like Figure 1-5 This is a schematic diagram of the structure of an electricity metering box according to a preferred embodiment of the present invention. In this embodiment, the electricity metering box includes a box body 1, which serves as the supporting foundation for the entire device. The front surface of the box body 1 has a first chamber 11 and a second chamber 12 for installing different components. To protect the internal components of the chambers, a first door 21 and a second door 22 are movably connected to the front surface of the box body 1 at the first chamber 11 and the second chamber 12 respectively via hinge assemblies 3. By opening and closing the first door 21 and the second door 22, the operation and protection of the internal components of the first chamber 11 and the second chamber 12 can be achieved.

[0030] In this embodiment, the electricity metering box features an innovative design in its connection structure between the housing 1 and the door. A mounting position 16 is provided on the surface of the housing 1 at a position opposite to the hinge assembly 3, providing a stable foundation for the installation of the hinge assembly 3. Simultaneously, a rotating block 213 is fixedly connected to the first door 21 and the second door 22 at a position opposite to the hinge assembly 3. A rotating cavity 214 is formed in the center of the surface of the rotating block 213, providing space for the rotation of the door.

[0031] The hinge assembly 3 is the core structure for achieving stable rotation and hovering of the door, consisting of a mounting base 31 and a pin 32. The rear end of the mounting base 31 is securely installed in the mounting position 16 with fasteners, ensuring the stability of the connection between the hinge assembly 3 and the housing 1.

The electricity meter 14 is connected to the short-circuit connector assemblies 13 via a plug-in method. Each short-circuit connector assembly 13 includes a support base 131 and a socket 132. The support base 131 is fixedly mounted on the surface of the mounting plate 111, and the socket 132 is rotatably connected to the lower part of the support base 131. This structural design allows the electricity meter 14 to be quickly connected via the socket 132. Compared to traditional wire connection methods, this simplifies the installation and replacement process of the electricity meter 14. Operators do not need to perform complex wiring operations, significantly improving the efficiency of installation and subsequent maintenance and replacement, and reducing operational difficulty.

[0034] In this embodiment, a guide rail frame 112 is fixedly installed below the mounting plate 111 in the first chamber 11. A miniature circuit breaker 15 is snapped onto the guide rail frame 112 at a position opposite to the shorting connector assembly 13, and the miniature circuit breaker 15 is connected to the shorting connector assembly 13 by a wire. The miniature circuit breaker 15 is installed on the guide rail frame 112 by snapping, which not only makes the circuit layout more orderly, but also facilitates the quick installation, disassembly and replacement of the miniature circuit breaker 15.

[0035] In addition, a maintenance opening 211 is provided on the first door 21 opposite to the miniature circuit breaker 15, and a maintenance cover 212 is rotatably connected to the inner wall of the maintenance opening 211. This design allows operators to perform routine inspections and maintenance on the miniature circuit breaker 15 without opening the entire first door 21, further improving the convenience of maintenance.
