Description

Technical Field

[0001] This utility model relates to the field of expandable electricity meter technology, specifically to an expandable electricity meter with a pluggable module. Background Technology

[0002] As smart grids evolve towards digitalization and intelligence, power metering equipment needs to meet diverse functional requirements and rapid upgrade and iteration demands. Plug-in modular expandable meters, with their flexible functional expandability and convenient maintenance, are widely used in power monitoring, load management, and demand-side response scenarios. Through modular design, users can quickly replace or add communication modules, metering modules, protection modules, etc., according to actual needs, significantly improving the flexibility and economy of meter usage.

[0003] In practical applications of extended-range electricity meters, their functional expansion primarily relies on the plug-in connection between the meter module and its corresponding slot. However, existing slots generally lack effective fixing structures, relying solely on simple mechanical connections to maintain the connection. Under external impacts or vibrations, the meter module is highly susceptible to detaching from the slot. This unstable connection not only leads to interrupted metering data and functional failure but also poses safety hazards, severely impacting the reliability and safety of the meter's operation, necessitating urgent technological improvements. Utility Model Content

[0004] The purpose of this invention is to provide an expandable electricity meter with a pluggable module to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes an expandable electricity meter with a pluggable module, including an electricity meter box, an electricity meter body inside the electricity meter box, a fixing mechanism inside the electricity meter box, and an anti-accidental contact mechanism on one side of the fixing mechanism; The fixing mechanism includes a support frame fixedly connected to the inner wall of the meter box. The support frame has grooves on both sides and multiple limiting grooves at equal intervals at both ends. Each limiting groove has a limiting block on its inner wall. A first connecting rod is fixedly connected between every two limiting blocks and is located inside the groove. One end of each of the two first connecting rods is fixedly connected to a gear, and the two gears are meshed. A second connecting rod is fixedly connected to the center of one side of one of the gears, and a handle is rotatably connected to the other end of the second connecting rod.

[0006] In one example, a rotating shaft is fixedly connected to one side of the support frame, and a retaining ring is rotatably connected to the outer wall of the rotating shaft.

[0007] In one example, the anti-accidental touch mechanism includes a plurality of first strip-shaped holes formed at the bottom of the inner wall of the support frame, each first strip-shaped hole having a first fixing seat fixedly connected to its inner wall, and each first fixing seat having a first baffle rotatably connected to one side.

[0008] In one example, the top of the inner wall of the support frame is provided with a plurality of second strip-shaped holes at equal intervals, and a second fixing seat is fixedly connected to the inner wall of each second strip-shaped hole.

[0009] In one example, a second baffle is rotatably connected to the top of each of the second fixing seats.

[0010] In one example, a torsion spring is embedded at the top of each of the second fixing bases.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. When the meter body reaches the designated position, a second connecting rod located on one side of the gear, with a handle on one side of the second connecting rod, will rotate when the handle is pulled. This will cause the internal gear to rotate, and the two gears will rotate in opposite directions. This will cause the limiting block located inside the support frame to change from horizontal to vertical, thus fixing the meter body in place. This prevents the meter body from falling off due to external forces during use, improving the safety of the meter body during use.

[0012] 2. The first strip-shaped hole on one side of the support frame is the insertion port for the contact point of the meter body. A first baffle is provided on its inner wall through the first fixing seat. The function of the first baffle is to prevent accidental electric shock during installation. A second strip-shaped hole is provided inside the support frame. A second fixing seat is provided on the inner wall of the second strip-shaped hole. A second baffle is provided on the top of the second fixing seat. The second baffle is perpendicular to the first baffle, so that when the second baffle is slid and pressed, the first baffle will open accordingly, thereby facilitating the insertion of the meter body into the interior.

The connecting rod 307 has a handle 308 on one side. Pulling the handle 308 will cause the second connecting rod 307 to rotate, which in turn will cause the internal gear 306 to rotate. Under the rotation of the two gears 306, the two gears 306 will rotate in opposite directions, which will drive the limiting block 304 located inside the support frame 301 to change from horizontal to vertical, thereby fixing the meter body 2 and preventing the meter body 2 from falling off due to external force during use, thus improving the safety of the meter body 2 during use.

[0018] Furthermore, a rotating shaft 309 is fixedly connected to one side of the support frame 301, and a fixing ring 310 is rotatably connected to the outer wall of the rotating shaft 309; The rotating shaft 309 located on one side of the support frame 301 and the fixing ring 310 on one side of the rotating shaft 309 allow the fixing ring 310 on one side to be rotated down after the meter body 2 is fixed, thereby fixing the handle 308 and preventing the handle 308 from springing back.

[0019] Furthermore, the anti-accidental touch mechanism 4 includes a plurality of first strip holes 401 formed at the bottom of the inner wall of the support frame 301. Each first strip hole 401 has a first fixing seat 402 fixedly connected to its inner wall, and each first fixing seat 402 has a first baffle 403 rotatably connected to one side.
