Technical Field

[0001] This utility model relates to the field of IoT electricity metering instruments, and in particular to an IoT electricity metering instrument that is easy to install. Background Technology

[0002] Electricity metering devices are instruments used to measure and record power generation, power supply or mutual power supply, plant power consumption, line loss power, and user power consumption. Electricity metering devices refer to the overall system consisting of electricity meters, active and reactive power meters, maximum demand meters, multi-rate electricity meters, etc. Metering transformers include voltage transformers, current transformers, and secondary connecting wires.

[0003] However, most IoT power metering instruments on the market currently use traditional bolt fixing methods, requiring the use of multiple tools such as wrenches and screwdrivers, making the operation cumbersome and complicated. Installers need to spend a considerable amount of time tightening the bolts, resulting in low installation efficiency and inconvenience. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Reference Figures 1-3An easy-to-install IoT power metering instrument includes a mounting plate 1 with four mounting holes 2. A square cover 3 is fixedly installed on one side wall of the mounting plate 1. A meter 7 is provided on one side of the square cover 3. A mounting frame 5 is fixedly installed on one side wall of the meter 7. The mounting frame 5 is adapted to the square cover 3 so that the mounting frame 5 can accurately align with the square cover 3, ensuring the accuracy and stability of the installation. Limiting holes 11 are provided on the four inner walls of the mounting frame 5. The square cover 3 is provided with mounting components.

[0024] The mounting assembly includes a rotating shaft 8 rotatably connected between a square cover 3 and a mounting plate 1. A worm gear 9 is fixedly mounted on the outer wall of the rotating shaft 8. A worm 10 is rotatably connected between the inner walls of the two sides of the square cover 3, meshing with the worm gear 9. One end of the worm 10 passes through one inner wall of the square cover 3 and is fixedly mounted with a knob 4 located outside the square cover 3. A rotating block 18 is fixedly mounted on the outer wall of the rotating shaft 8. The rotating block 18 has four sliding grooves 17, all of which are arc-shaped. The arc-shaped sliding grooves 17 allow the sliding column 16 to slide along a specific trajectory within the sliding grooves 17. Each of the four sliding grooves 17 has a sliding column 16 slidably connected to it. Each of the four sliding columns 16 has a moving block 15 rotatably connected to the side away from the worm gear 9. The upper part has four mounting slots 14, and guide rods 13 are fixedly connected between the inner walls of the two ends of the four mounting slots 14. Four moving blocks 15 are slidably fitted on the four guide rods 13 respectively. The four moving blocks 15 are slidably connected to the inner walls on both sides of the four mounting slots 14 to prevent the moving blocks 15 from shifting or shaking during sliding. The four outer walls of the square cover 3 are provided with through holes 12 that communicate with the interior. Limiting rods 6 are fixedly installed on the side wall of the four moving blocks 15 away from the rotating shaft 8. The diameter of the through hole 12 is the same as the diameter of the limiting hole 11. The limiting rod 6 is adapted to the limiting hole 11 to ensure that the limiting rod 6 can be smoothly inserted into the limiting hole 11, so as to achieve a firm limit on the mounting frame 5 and ensure the stability and reliability of the meter 7 installation.

[0025] In use, the mounting plate 1 is fixed by the mounting hole 2 and bolts. When installing the measuring instrument 7, first, the mounting frame 5 on the measuring instrument 7 is engaged with the square cover 3. Then, the knob 4 located outside the square cover 3 is rotated. The knob 4 drives the worm gear 10 to rotate. Through the meshing transmission between the worm gear 10 and the worm wheel 9 fixed on the rotating shaft 8, the rotating shaft 8 rotates between the square cover 3 and the mounting plate 1, thereby driving the rotating block 18 to rotate. The sliding column 16 in the arc-shaped sliding groove 17 on the rotating block 18 slides accordingly, pushing the moving block 15, which is slidably connected to the inner wall of the mounting groove 14 and is slidably sleeved on the guide rod 13, to move outward. This causes the limiting rod 6 on the moving block 15 to extend through the through hole 12 and insert into the limiting hole 11 of the mounting frame 5, completing the installation. When disassembling, the knob 4 is rotated in the opposite direction. Through the above transmission process, the rotating block 18 rotates in the opposite direction. The sliding column 16 drives the moving block 15 to move inward. The limiting rod 6 is pulled out from the limiting hole 11 and retracts into the square cover 3, allowing the measuring instrument 7 to be removed.

[0026] 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.
