Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electricity metering boxes, specifically a new type of 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] Currently, most electricity metering boxes on the market are made of stainless steel, and their cable inlets are usually located at the bottom of the box. Since there are no protective devices installed at this cable inlet, when the cable enters from the bottom and is bent, the edge of the inlet is very easy to scratch or even cut the cable, posing a certain safety hazard and risk of cable damage. Summary of the Invention
[0004] The purpose of this utility model is to provide a new type of 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: A novel electricity metering box includes a box body, an installation cavity is provided inside the box body, and an installation port is provided on the bottom surface of the box body, the installation port communicating with the installation cavity. An inlet assembly is installed in the installation port, the inlet assembly including an installation plate and an inlet cylinder. The installation plate is installed on the inner wall of the installation cavity at the installation port, and multiple inlet ports are provided on the surface of the installation plate. An inlet cylinder is installed in each inlet port. The installation plate and the inlet cylinder are designed at an inclined angle. Connection holes are provided on the surface of the installation plate at both ends of the inlet ports, and installation holes are provided on the inner wall of the installation cavity at positions opposite to the connection holes. The installation holes and connection holes are connected by fastening bolts.
[0006] Preferably, the inner wall surface of the infeed cylinder is coated with a wear-resistant layer.
[0007] Preferably, an electrical mounting bracket is fixedly installed in the mounting cavity at a position relative to the incoming line assembly, and a door is fixedly connected to the front surface of the housing at a position relative to the mounting cavity via a hinge. Beneficial effects
[0008] Compared with existing technologies, the beneficial effects of this utility model are as follows: This invention features a cable inlet assembly consisting of a mounting plate and a cable inlet tube at the bottom mounting port of the enclosure. The cable enters the enclosure through the cable inlet tube. The cable inlet tube's structural design effectively wraps and guides the cable, preventing direct contact between the cable and the edge of the mounting port. This fundamentally solves the problem of cable scratching and cutting caused by the lack of protection at traditional cable inlets, significantly reducing safety hazards caused by cable damage and ensuring the stable operation of the electricity metering box. The mounting plate of this utility model is designed with an inclined angle between it and the cable inlet tube. This inclined structure provides more space for cable bending operations, making it easier for the cable to smoothly transition during the cable entry process and reducing operational resistance during installation. At the same time, the mounting plate is detachably connected to the inner wall of the housing mounting cavity via fastening bolts. When it is necessary to replace or maintain the cable inlet assembly, the mounting plate can be easily removed simply by unscrewing the bolts, simplifying the installation and maintenance process and improving the operational efficiency of the staff.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0013] like Figure 1-3 This is a structural schematic diagram of a novel energy metering box according to a preferred embodiment of the present invention. In this embodiment, the novel energy metering box includes a box body 1, which serves as the main body supporting the entire metering box. An installation cavity 11 for installing various electrical components is provided inside. A door 4 is fixedly connected to the front surface by a hinge, which can realize the closing and opening of the installation cavity 11 to ensure the safety protection of the internal components.
[0014] In this embodiment, the inlet assembly 2 is the core innovative part of this metering box. It consists of a mounting plate 21 and an inlet tube 22, and is installed at the mounting port 12 at the bottom of the box body 1. The mounting plate 21 is fixed to the inner wall of the mounting cavity 11 at the mounting port 12 by fastening bolts. Multiple inlet ports 211 are opened on its surface, and an inlet tube 22 is installed in each inlet port 211. In this embodiment, the mounting plate 21 and the cable inlet 22 are designed with an inclined angle. This special structure provides ample space for cable bending operations, allowing for a smooth transition during cable entry and effectively reducing operational resistance during installation. Simultaneously, the surface of the mounting plate 21 has connecting holes 212 at both ends of the cable inlet 211, and corresponding mounting holes 13 are provided on the inner wall of the mounting cavity 11. Fastening bolts passing through the connecting holes 212 and mounting holes 13 enable a detachable connection between the mounting plate 21 and the housing 1. This connection method allows for easy removal of the mounting plate 21 simply by unscrewing the bolts when the cable inlet assembly 2 needs replacement or maintenance, greatly simplifying the installation and maintenance process and significantly improving the operational efficiency of staff.
[0015] In this embodiment, a wear-resistant layer is attached to the inner wall surface of the cable inlet drum 22. This wear-resistant layer is made of high-strength wear-resistant material, which can effectively improve the wear resistance of the cable inlet drum 22. During long-term use, it can reduce frictional loss between the cable and the inner wall of the cable inlet drum 22, extend the service life of the cable inlet drum 22, and prevent the cable from being damaged by friction, thus further ensuring the stable operation of the metering box.
[0016] In this embodiment, an electrical mounting bracket 3 is fixedly installed in the mounting cavity 11 at a position opposite to the incoming line assembly 2, providing a stable mounting platform for metering electrical components such as electricity meters, making the installation layout of electrical components more reasonable, and facilitating cable connection and subsequent maintenance and repair.
[0017] Working principle First, determine the direction from which the cable enters from the bottom of the metering box. Tilt the cable inlet tube 22 towards the cable direction. Place the mounting plate 21 on the inner wall of the mounting cavity 11 at the mounting opening 12, aligning the connection hole 212 on the surface of the mounting plate 21 with the mounting hole 13 on the inner wall of the mounting cavity 11. Securely fix the mounting plate 21 to the box body 1 using fastening bolts passed through the connection hole 212 and the mounting hole 13. Install the cable inlet tube 22 inside the cable inlet 211 of the mounting plate 21, ensuring proper installation. After completing the installation of the cable inlet assembly, install electrical components such as the energy meter on the electrical mounting bracket 3 and connect the cables. The cables enter the mounting cavity 11 through the cable inlet tube 22 and connect to the electrical components. Finally, close the door 4 to complete the installation of the entire new energy metering box.
[0018] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
