Technical Field

[0001] This utility model relates to the field of smart energy meter technology, and in particular to a three-phase harmonic smart energy meter. Background Technology

[0002] With the continuous development of society and the continuous progress of technology, the technology related to smart energy meters is also constantly improving, and the types of smart energy meters are also increasing. At present, three-phase harmonic smart energy meters have high intelligence and are widely used. They can be used to measure electrical energy.

[0003] The three-phase harmonic smart energy meters currently in use are inconvenient to inspect and repair. The front cover of the energy meter is fixed with multiple screws. When inspecting, it is not only time-consuming and laborious to unscrew multiple screws, but also easy to strip the screw threads during the operation, which is not conducive to the use of the three-phase harmonic smart energy meter. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: the three-phase harmonic smart energy meter currently in use is inconvenient to repair. The front cover of the energy meter is fixed by multiple screws. During repair, it is not only time-consuming and laborious to unscrew multiple screws, but also easy to strip the screw threads during the operation, which is not conducive to the use of the three-phase harmonic smart energy meter. Therefore, a three-phase harmonic smart energy meter is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A three-phase harmonic smart energy meter includes an energy meter body, a front cover is provided on one side of the energy meter body, a plurality of U-shaped plates are fixedly connected to the surface of the front cover near the energy meter body, and a plurality of symmetrically arranged bent rods are installed on the energy meter body by a plurality of first springs, and a pressing block is fixedly connected to one end of each bent rod.

[0007] A sliding assembly is provided on the main body of the electricity meter. The sliding assembly includes a fixed frame that is slidably installed on the main body of the electricity meter. A plurality of pressing rods are fixedly connected to one side surface of the fixed frame. Two mounting holes are opened on the main body of the electricity meter. A fixed plate is fixedly connected to each mounting hole. A sliding rod is slidably arranged on each fixed plate. The sliding rod is fixedly connected to the fixed frame.

[0008] Preferably, each of the slide bars is fitted with a second spring, one end of the second spring is fixedly connected to the slide bar, and the other end of the second spring is fixedly connected to the fixing plate.

[0009] Preferably, the cross-section of each extrusion block is arranged in a right-angled triangle, and one end of each extrusion rod is in contact with the inclined surface of the corresponding extrusion block.

[0010] Preferably, the inside of the electricity meter body is fixedly connected with multiple positioning rods with an L-shaped cross-section, and multiple positioning grooves are opened on one side surface of the front cover.

[0011] Preferably, a rotating block with a T-shaped cross-section is threadedly connected to the upper fixing plate, and one end of the rotating block is in contact with the surface of the fixing frame.

[0012] Preferably, the back of the electricity meter body is provided with multiple threaded grooves, and the multiple threaded grooves are arranged symmetrically.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] After the rotating block separates from the fixed frame, the fixed frame is pushed to move closer to the fixed plate. When each pressing rod moves against the inclined surface of the corresponding pressing block, the pressing block will move, which in turn causes the bending rods to slide relative to the energy meter body. After multiple bending rods move, they will separate from each U-shaped plate. Then, the front cover can be pulled outward to separate it from the energy meter body. This makes it easy and quick to separate the front cover from the energy meter body, which is convenient for maintenance of the energy meter body. The operation is relatively simple but convenient, saving time and effort, which is beneficial to the use of three-phase harmonic smart energy meters. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0022] Reference Figures 1-4 A three-phase harmonic smart energy meter includes an energy meter body 1, a front cover 2 on one side of the energy meter body 1, a plurality of U-shaped plates 12 fixedly connected to the surface of the front cover 2 near the energy meter body 1, a plurality of symmetrically arranged bent rods 11 mounted on the energy meter body 1 by a plurality of first springs 13, a pressing block 14 fixedly connected to one end of each bent rod 11, a sliding assembly on the energy meter body 1, the sliding assembly including a fixed frame 3 slidably mounted on the energy meter body 1, a plurality of pressing rods 6 fixedly connected to one side surface of the fixed frame 3, two mounting holes 9 on the energy meter body 1, a fixed plate 7 fixedly connected in each mounting hole 9, a sliding rod 4 slidably mounted on each fixed plate 7, and the sliding rod 4 and the fixed frame 3 fixedly connected.

[0023] Each slide rod 4 is fitted with a second spring 8. One end of the second spring 8 is fixedly connected to the slide rod 4, and the other end of the second spring 8 is fixedly connected to the fixing plate 7. The cross-section of each pressing block 14 is set in a right-angled triangle. One end of each pressing rod 6 is in contact with the inclined surface of the corresponding pressing block 14. When the fixing frame 3 is pushed to move closer to the fixing plate 7, the second spring 8 deforms. When each pressing rod 6 moves against the inclined surface of the corresponding pressing block 14, the pressing block 14 will move, thereby causing each bent rod 11 to slide relative to the energy meter body 1. Since one end of each first spring 13 is fixedly connected to the corresponding bent rod 11, and the other end of each first spring 13 is fixedly connected to the energy meter body 1, multiple first springs 13 will deform.

[0024] The inside of the electricity meter body 1 is fixedly connected with multiple positioning rods 10 with an L-shaped cross section. Multiple positioning grooves are opened on one side surface of the front cover 2. When the front cover 2 is installed with the electricity meter body 1, one end of each positioning rod 10 will be inserted into the corresponding positioning groove to perform preliminary positioning treatment for the installation of the front cover 2.

[0025] A rotating block 5 with a T-shaped cross-section is threaded onto the upper fixed plate 7. One end of the rotating block 5 is in contact with the surface of the fixed frame 3. In the initial state, the end face of the rotating block 5 is in contact with the surface of the fixed frame 3, which can prevent the fixed frame 3 from moving closer to the fixed plate 7. At this time, one end of each bent rod 11 passes through the corresponding U-shaped plate 12, and the positioning rod 10 is engaged with the positioning groove. That is, the front cover 2 is firmly connected to the energy meter body 1. Multiple threaded grooves are opened on the back of the energy meter body 1. The multiple threaded grooves are symmetrically arranged. The multiple threaded grooves facilitate the use of bolts to fix the energy meter body 1.

[0026] In this invention, during disassembly, the rotating block 5 is first rotated. During the rotation of the rotating block 5, one end face of it moves against the surface of the fixed frame 3. When the rotating block 5 rotates upward 90 degrees, it disengages from the fixed frame 3 and cannot prevent the fixed frame 3 from moving closer to the fixed plate 7. Then, the fixed frame 3 is pushed to move closer to the fixed plate 7, causing the second spring 8 to deform. When each pressing rod 6 moves against the inclined surface of the corresponding pressing block 14, the pressing block 14 will move, thereby causing... Each bent rod 11 slides relative to the energy meter body 1. In the initial state, one end of each bent rod 11 passes through the corresponding spiral plate 12, which prevents the spiral plate 12 from moving. After multiple bent rods 11 move, they will detach from each spiral plate 12. Then, pull the front cover 2 outward to detach it from the energy meter body 1. This makes it easy and quick to detach the front cover 2 from the energy meter body 1, which is convenient for maintenance of the energy meter body 1. The operation is relatively simple but convenient, saving time and effort, which is beneficial to the use of three-phase harmonic smart energy meters.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
