Description

Technical Field

[0001] This utility model belongs to the technical field of electricity metering boxes, specifically an electricity metering box with a hanging structure. Background Technology

[0002] Electricity metering boxes are devices used to measure and record electricity consumption. They accurately measure and record users' electricity consumption, providing a basis for power companies to settle electricity bills. They can monitor parameters such as load, voltage, current, and frequency in the power system, promptly detect abnormal loads and power quality problems, realize load management and dispatch, and ensure the stable operation of the power system. Through the communication network in the smart grid, they upload electricity consumption data, load data, and power quality data to the power company's server, realizing remote meter reading, billing, monitoring, and management functions. In residential communities, they are used for electricity metering and billing for households. In industrial enterprises, they can measure and manage the electricity consumption of various workshops and equipment within the enterprise, helping enterprises to conduct energy cost accounting and energy-saving management. In commercial buildings such as shopping malls and office buildings, they can separately meter and charge the electricity consumption of different tenants. They can also be used in electric vehicle charging stations to monitor the electricity consumption and charging status of electric vehicle charging stations, realizing remote billing and management.

[0003] In existing technologies, electricity metering boxes are typically installed on walls using bolts. This connection method makes subsequent disassembly and reassembly of the electricity metering box inconvenient. Some electricity metering boxes can also be installed by hooking them, for example, by setting hooks on the back or side of the metering box. The metering box is then hooked onto a pre-installed hanging rod or ring. However, this simple hooking method lacks positioning for the electricity metering box. The metering box can be removed simply by lifting it upwards, which poses certain safety hazards.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 6 As shown, this utility model provides an energy metering box with a hanging structure, including a fixing plate 1, and the fixing plate 1 is connected to the box body 3 through a hanging assembly 2;

[0030] The mounting assembly 2 includes two symmetrically arranged hook plates 21 installed on the fixed plate 1. A hanging frame 22 is hung on the hook plate 21 and the hanging frame 22 is fixedly connected to the box body 3. A positioning assembly 23 is provided between the hook plate 21 and the hanging frame 22. When the metering box needs to be inspected, maintained or replaced, the mounting assembly 2 facilitates the quick disassembly and installation by the staff, improves maintenance efficiency, shortens power outage time, and can be positioned and fixed to prevent easy removal from the box body 3.

[0031] The positioning component 23 includes a mounting groove 231 on the hook plate 21, a movable plate 232 is provided in the mounting groove 231, and an insertion groove 233 is provided on the inner wall of the hanging frame 22 at a position corresponding to the movable plate 232. A toothed plate 234 is fixedly connected to the side of the movable plate 232 away from the insertion groove 233. A toothed column 235 is engaged with the toothed plate 234. A rotating rod 236 is fixedly connected to the toothed column 235. A knob 237 is fixedly connected to the top of the rotating rod 236 through the hook plate 21, which positions and fixes the hanging frame 22, that is, positions and fixes the box 3, and can prevent the box 3 from being accidentally removed.

[0032] Specifically, fixing bolts 4 are provided at the four corners of the fixing plate 1 to fix the fixing plate to the wall. Weight reduction holes 5 are provided on the fixing plate 1 to reduce the weight of the fixing plate 1.

[0033] Furthermore, a positioning groove 6 is provided on the fixed plate 1 at the position corresponding to the hook plate 21. The positioning groove 6 is slidably connected to the hook plate 21 through the positioning slider 7. A telescopic component 8 is connected between the hook plates 21, which can adjust the distance between the two hook plates 21 to realize the hanging of boxes 3 of different sizes, expand the applicability of the hanging component 2, and facilitate the use of the hanging structure.

[0034] Furthermore, the telescopic component 8 includes a threaded tube 81, which is connected to a fixing block 82 via a bearing. The fixing block 82 is fixedly connected to the fixing plate 1. Threaded rods 83 are threadedly connected to both ends of the threaded tube 81, and hook plates 21 are fixedly connected to the ends of the threaded rods 83.

[0035] It is worth noting that the front of the box 3 is connected to the box door 9 by a hinge, and the box door 9 is equipped with a handle 10 and an observation window 11.

[0036] It is worth noting that the enclosure 3 is equipped with current transformers, metering instruments, switching equipment, and protection devices. The enclosure 3 has a metal shell. Current enters the enclosure 3 through the busbar, and after being transformed by the current transformer, the signal is transmitted to the metering instrument. The metering instrument measures and records the electrical energy. This is existing technology and will not be elaborated further.

[0037] Working principle and process: Fixing plate 1 and hook plate 21 and positioning component 23 of the hanging assembly 2 are fixed by fixing bolt 4 on the fixing plate 1. The hanging frame 22 of the fixed connection box 3 is hung on the hook plate 21. Rotating the knob 237 of the positioning component 23 will rotate the rod 236 and drive the tooth column 235 to rotate, which will cause the meshing tooth plate 234 to move, thereby driving the movable plate 232 to move and extend into the groove 233 inside the inner wall of the hanging frame 22, thus fixing the hanging frame 22, which is also fixing the box 3. When installing boxes 3 of different sizes, rotating the threaded tube 81 of the telescopic component 8 will change the length of the threaded rod 83 extending out of the threaded tube 81, thereby adjusting the distance between the two hook plates 21, and thus installing boxes 3 of different sizes.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
