Description

Technical Field

[0001] This utility model relates to the field of power system technology, specifically to a portable installed electricity meter. Background Technology

[0002] As the core component of power metering equipment, the installation method of electricity meters directly affects the ease of use, maintenance efficiency and long-term stability. Traditional electricity meter installation techniques mostly use bolt fixing or guide rail clamping.

[0003] As disclosed in announcement number CN222618696U, a quick-release energy meter specifically relates to the field of energy meter technology, including an installation component. The installation component has an energy meter assembly embedded in its front side. The installation component includes an installation plate with an installation groove on its front side and a threaded groove on one side of the installation groove. A threaded rod is rotatably installed in the threaded groove. This quick-release energy meter allows the energy meter body to be easily hung on the docking plate by inserting a docking bevel plate into the corresponding docking bevel slot. Then, by rotating the threaded rod, the energy meter is moved into the installation groove, completing the installation. This effectively simplifies the installation steps, reduces installation difficulty, and improves installation efficiency. Furthermore, when the energy meter needs to be disassembled, it can be easily removed from the docking plate by controlling the energy meter to extend out of the installation groove, making disassembly more convenient and faster.

[0004] Another example is the electricity meter disclosed in announcement number CN218240175U, which is designed for quick installation. It includes: a distribution box, an electricity meter body, a sealing strip, and an observation window. The electricity meter body is connected inside the distribution box, which serves as the connection base. A limit frame is connected to one side of the electricity meter body. A telescopic cylinder is connected to one side of the distribution box and engages with a mating groove. A baffle is connected to the top of a spring, and a socket is located above the mating groove. By pushing the socket plate back to its original position with the spring, the socket plate can be inserted into the socket, facilitating the installation and removal of the electricity meter body. Rotating the bidirectional screw moves two sets of clamping plates simultaneously to clamp the wires, ensuring a more secure connection to the bottom of the electricity meter body and preventing them from falling off. The sealing strip is installed on the outside of the observation window through the engagement of the male and female fasteners, preventing it from falling off even after prolonged use.

[0005] In the aforementioned existing technologies, bolt fixing requires multiple bolts to fix the electricity meter to the wall or distribution box, which is cumbersome, relies on professional tools, and is time-consuming. The quick-connect method requires an additional locking mechanism, which in turn requires many components inside the mounting base, increasing the thickness of the mounting base. As a result, the electricity meter may experience unstable connection during the connection process. Utility Model Content

[0006] The purpose of this invention is to provide a portable electricity meter that solves the problems of the prior art, such as complicated fixed connection operation steps, increased wall thickness of the mounting base due to quick snap-fit, and unstable connection.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable energy meter, including a meter body, a locking plate, a mounting base, and a locking component. The locking plate is rotatably connected to the meter body, and the mounting base is installed on a wall. It has an embedded groove that is adapted to the locking plate and is inclined. The locking plate and the mounting base are detachably connected through the cooperation of the locking plate and the embedded groove. The locking component is provided on the mounting base to lock the locking plate and the mounting base after connection.

[0008] Furthermore, the locking component includes a latch that is slidably connected to the mounting base along the direction of the vertical embedded groove sidewall and a locking groove formed on the lock plate and used in conjunction with the latch. The latch is slidably connected to the mounting base via a guide rod that is fixedly connected to the guide seat. A locking spring is sleeved on the outer wall of the guide rod, and both ends of the locking spring are fixedly connected to the latch and the mounting base, respectively.

[0009] Furthermore, it also includes an unlocking component for unlocking the lock plate. The unlocking component includes a winding shaft rotatably connected to the mounting base and a winding rope wound on the winding shaft with its end fixedly connected to the lock tongue. The rotation of the winding shaft drives the winding rope to wind, causing the lock tongue to slide along the installation direction to achieve unlocking.

[0010] Furthermore, a return spring is fixedly connected to the side of the locking plate near the watch body, and the end of the return spring away from the locking plate is fixedly connected to the watch body.

[0011] Furthermore, one end of the winding shaft has a rotating block that extends through and is coaxially fixed to the mounting base.

[0012] In the above technical solution, the portable installation energy meter provided by this utility model has a locking plate that is rotatably connected to the meter body. After aligning the end of the locking plate with the embedding groove and pressing the meter body, the locking plate can slide into the embedding groove along the opening direction of the groove. Compared with the horizontally set embedding groove, the angle of the embedding groove is larger, so the wall thickness of the mounting base can be greatly reduced. This saves raw materials for the mounting base and makes the mounting base occupy very little space, greatly shortening the distance between the energy meter and the wall. Then, with the locking component, the meter body is fixedly connected to the connecting base. The fixed connection method makes the energy meter connection more stable than the snap-fit ​​and hook-fit. Moreover, compared with the bolt fixed connection of the prior art, this technical solution only requires pressing the meter body, which is simple to operate and saves time and effort.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Please see Figures 1-7 This utility model provides a portable energy meter, including a meter body 1, a locking plate 2, a mounting base 3, and a locking member 4. The locking plate 2 is rotatably connected to the back of the meter body 1. The mounting base 3 is mounted on a wall and has an inclined groove 22 that is adapted to the locking plate 2, with the inclination angle between 60° and 80° relative to the horizontal direction. The locking member 4 is provided on the mounting base 3 to lock the locking plate 2 and the mounting base 3 after connection. Since the locking plate 2 is rotatably connected to the meter body 1, by aligning the end of the locking plate 2 with the groove 22 and pressing the meter body 1, the locking plate 2 can be pushed into the groove 22 along its opening direction.

[0018] Compared to the horizontally set embedding groove 22, the setting angle of the embedding groove 22 is larger, which can greatly reduce the wall thickness of the mounting base 3. While saving raw materials, the mounting base 3 occupies very little space, which greatly shortens the distance between the meter body 1 and the wall. Then, with the locking part 4, the meter body 1 is fixedly connected to the connecting base. The fixed connection method makes the meter body 1 more stable than the snap-fit ​​and hook-fit. Moreover, compared with the bolt fixed connection of the existing technology, this technical solution only requires pressing the meter body 1, which is simple to operate and saves time and effort.

[0019] Reference Figure 5-6 The locking component 4 includes a latch 41, a lock groove 42, a guide rod 43, and a locking spring 44. The latch 41 is located above the insertion groove 22 and is slidably connected to the insertion groove 22. It has a guide hole and an inclined surface for the lock plate 2 to slide into the insertion groove 22. The lock groove 42 is formed on the lock plate 2 and its size is adapted to the latch 41. One end of the guide rod 43 is fixedly connected to the guide seat, and the other end is clearance-fitted with the guide hole, and is slidably connected to the latch 41 through the guide hole.

[0020] The locking spring 44 is sleeved on the guide rod 43, and its two ends are fixedly connected to the locking tongue 41 and the mounting base 3, respectively.

[0021] The locking tongue 41 is slidably connected to the mounting base 3 along the direction of the vertical embedded groove 22 side wall. The locking groove 42 is opened on the locking plate 2 and is used in conjunction with the locking tongue 41. The guide rod 43 is fixedly connected to the mounting base 3. The locking tongue 41 has a guide hole. The guide rod 43 is slidably connected in the guide hole. A locking spring 44 is also sleeved on the outer wall of the guide rod 43. One end of the locking spring 44 is fixedly connected to the locking tongue 41, and the other end is fixedly connected to the mounting base 3.

[0022] In the above technical solution, the elastic force of the locking spring 44 is a contraction force, which causes the locking tongue 41 to have a tendency to move towards the locking plate 2. When the watch body 1 is pressed until the locking plate 2 enters the embedding groove 22, the arc-shaped surface of the locking tongue 41 slides away from the locking plate 2 under the squeezing force of the locking plate 2. At this time, the locking spring 44 is stretched and accumulates elastic potential energy. When the locking plate 2 is completely inserted into the embedding groove 22, the locking groove 42 on the locking plate 2 is exactly opposite to the locking tongue 41. At this time, under the action of the elastic potential energy of the locking spring 44, the locking tongue 41 is pushed to slide towards the locking plate 2 and is embedded in the locking groove 42.

[0023] Reference Figure 3-4 as well as Figure 7The mounting base 3 is also provided with an unlocking component 5 for unlocking the lock plate 2. The unlocking component 5 includes a winding shaft 51, a winding rope 52 and a rotating block 53. The winding shaft 51 is rotatably connected to the mounting base 3. The winding rope 52 is wound around the winding shaft 51 and its end is fixedly connected to the lock tongue 41. One end of the winding shaft 51 extends through the mounting base 3 and is coaxially fixedly connected to the rotating block 53.

[0024] Preferably, the rotating block 53 has a circular array with patterns suitable for ergonomics. When the electricity meter needs to be disassembled, the rotating block 53 is rotated, which in turn drives the winding shaft 51 to rotate. The winding shaft 51 winds the winding rope 52 to shorten it, which in turn pulls the locking tongue 41 to slide away from the locking groove 42. At this time, the meter body 1 can be held and moved away from the mounting base 3 to complete the disassembly.

[0025] It is worth mentioning that a return spring 21 is also fixedly connected to the side of the locking plate 2 near the watch body 1. The end of the return spring 21 away from the locking plate 2 is fixedly connected to the watch body 1. Therefore, during the disassembly process, the elastic force of the return spring 21 will also help the disassembly personnel to disassemble the watch body 1. In addition, the return spring 21 will make the locking plate 2 and the watch body 1 form a fixed angle, so that the locking plate 2 is directly facing the entrance of the embedded groove 22, which facilitates the installation work of the next cycle.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
