[0002] Smart meters are one of the basic devices for data acquisition in smart grids. They are responsible for the collection, measurement, and transmission of raw electrical energy data, and are the foundation for information integration, analysis, optimization, and presentation. In addition to the basic electricity metering function of traditional meters, smart meters also possess intelligent functions such as bidirectional multi-rate metering, user-end control, bidirectional data communication with multiple data transmission modes, and anti-theft features to adapt to smart grids and the use of new energy sources.

[0003] When installing existing electricity meters, they are generally mounted inside the distribution box or on the wall using at least two or more screws. After installation, the screws used for disassembly are directly exposed, making them easy for non-professionals to disassemble, posing a safety hazard. While some electricity meters are installed with multiple lead seals, making them difficult for non-professionals to disassemble, the lead seals are often made of soft metal or plastic. Once cut or opened, they cannot be restored. Even if a professional removes the meter, a new lead seal must be applied after each disassembly and repair, increasing the cost of meter maintenance. Utility Model Content

[0006] As a further improvement of this utility model, the top two sides of the guide rail are integrally formed with first locking blocks, and the top two sides of the slider are integrally formed with second locking blocks. When the slider slides to the preset position, the upper surfaces of the first locking blocks and the second locking blocks are located on the same horizontal plane, and the locking holes are located on the opposite sides of the two first locking blocks.

[0007] As a further improvement of this utility model, a pinhole is provided in the center of each of the two snap-fit ​​holes in a transverse direction. The pinhole is connected to the snap-fit ​​hole, and the diameter of the snap-fit ​​hole is larger than the diameter of the pinhole.

[0008] As a further improvement of this utility model, the second card block has a movable cavity for the card connector to move laterally, the card connector is movably engaged in the movable cavity, and a magnetic block is embedded in the side of the card connector away from the movable cavity.

[0009] A magnetic absorbing piece is fixedly connected inside the snap-fit ​​hole. The magnetic absorbing piece and the magnetic block are attracted to each other by opposite polarities. A through hole with the same diameter as the pinhole is opened through the center of the magnetic absorbing piece. The magnetic block and the magnetic absorbing piece have the same diameter.

[0010] As a further improvement of this utility model, limit grooves are formed through both sides of the inner wall of the slide groove in a vertical direction, and limit strips are fixedly connected to both sides of the sliding member at positions corresponding to the limit grooves. The shape and size of the limit strips are adapted to the limit grooves.

[0011] As a further improvement of this utility model, a hanging hole is provided through the front of the slider near the top, and the inner walls of the hanging hole are rounded and chamfered on both sides. The hanging hole is used to hook the slider for sliding.

[0012] As a further improvement of this utility model, threaded holes for fixing are provided through the four corners of the mounting plate, and docking blocks are fixedly connected to the four corners of the meter body near the mounting plate. The mounting plate has docking slots at the positions corresponding to the docking blocks, and the size of the docking blocks and the docking slots are adapted to each other.

[0013] As a further improvement of this utility model, the mounting plate is fixedly connected to the plug block at the central position between the guide rails, and the meter body is fixedly connected to the mounting plate on the side close to the mounting plate. The fixing plate is fixedly connected to the plug sleeve, and the meter body is connected to the mounting plate through the plug sleeve and the plug block.

[0014] After the plug-in block and the plug-in sleeve are connected, a first insertion hole and a second insertion hole are opened in the vertical direction to penetrate the plug-in block and the plug-in sleeve.

[0015] This utility model also provides an electricity meter, including a detachable meter fixing structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this invention, the locking component is hidden in a non-visible area on the back of the meter. Combined with a magnetic snap-fit ​​and a pinhole, disassembly requires inserting a pin into the pinhole to actuate the magnetic component, thus reducing the possibility of accidental operation by non-professionals. While the lead seal needs to be replaced if damaged, the magnetic snap-fit ​​assembly and the limiting plate in this solution are reusable metal components. During professional repairs, after releasing the magnetic lock with tools, the slide rail assembly can completely remove the plate. The entire disassembly process does not cause any component damage, saving on repair costs. Attached Figure Description

[0033] Please see Figure 1-9This utility model discloses a detachable electricity meter fixing structure, comprising: an electricity meter body 1 and a mounting plate 2, wherein the electricity meter body 1 and the mounting plate 2 are detachably connected; a sliding assembly 3, the sliding assembly 3 including a guide rail 31 and a sliding member 32, the guide rail 31 being fixed to the mounting plate 2 and forming a sliding groove 33 together with the mounting plate 2, the sliding member 32 being slidably connected to the sliding groove 33 and being detachable from the sliding groove 33, the guide rail 31 being provided with a snap-fit ​​hole 312 communicating with the sliding groove 33, and the sliding member 32 being provided with a snap-fit ​​member 323 that can reciprocate relative to the sliding member 32. The snap-fit ​​component 323 includes an installation position 4 and a snap-fit ​​position 41. When the snap-fit ​​component 323 is in the installation position 4, the slider 32 can slide in the slide groove 33. When the slider 32 moves to the preset position, the snap-fit ​​component 323 can move from the installation position 4 to the snap-fit ​​position 41 and snap into the snap-fit ​​hole 312, so that the slider 32 is relatively fixed in the slide groove 33. The slider 32 and the guide rail 31 are both made of aluminum alloy that cannot be magnetically fixed with a magnet, so as to prevent their own material from affecting the magnetic fixation between the magnetic block 324 and the magnetic sheet 314.

[0034] Please see Figure 6 and Figure 8 In this embodiment, the guide rail 31 has a first locking block 311 integrally formed on both sides of its top end, and the slider 32 has a second locking block 321 integrally formed on both sides of its top end. When the slider 32 slides to the preset position, the upper surfaces of the first locking block 311 and the second locking block 321 are on the same horizontal plane, and the locking hole 312 is located on the opposite surface of the two first locking blocks 311. This design allows the slider 32 to lock and limit itself by the shape structure between the first locking block 311 and the second locking block 321 when it slides down to lock, making the locking more convenient and quick, without having to consider where to stop sliding.

[0035] Both snap-fit ​​holes 312 have a pin hole 313 extending laterally through their centers. The pin hole 313 communicates with the snap-fit ​​hole 312. The diameter of the snap-fit ​​hole 312 is larger than the diameter of the pin hole 313. This design allows the snap-fit ​​part 323 to be pushed back into the movable cavity 322 by inserting a pin into the pin hole 313 when disassembly and maintenance are required. This causes the sliding part 32 to lose its restriction and return to a sliding state.

[0036] The second card block 321 has a movable cavity 322 for the card connector 323 to move laterally. The card connector 323 is movably engaged in the movable cavity 322. A magnetic block 324 is embedded in the side of the card connector 323 away from the movable cavity 322. In some embodiments, a spring can also be provided in the movable cavity 322. The spring's rebound force pushes the magnetic block 324 into the card hole 312 to achieve card engagement and fixation.

[0037] A magnetic absorbing piece 314 is fixedly connected inside the snap-fit ​​hole 312. The magnetic absorbing piece 314 is fixed by adhesive. The magnetic absorbing piece 314 and the magnetic absorbing block 324 are attracted by opposite polarities. A through hole with the same diameter as the pinhole 313 is opened through the center of the magnetic absorbing piece 314. The magnetic absorbing block 324 and the magnetic absorbing piece 314 have the same diameter. This design allows the snap-fit ​​member 323 to be brought into the snap-fit ​​hole 312 by the magnetic attraction between the magnetic absorbing piece 314 and the magnetic absorbing block 324 when it moves to the snap-fit ​​hole 312, so as to achieve snap-fit ​​limiting.

[0038] Limiting grooves 37 are vertically opened on both sides of the inner wall of the slide groove 33. Limiting strips 36 are fixedly connected to the positions on both sides of the sliding member 32 corresponding to the limiting grooves 37. The shape and size of the limiting strips 36 are adapted to the limiting grooves 37. This design allows the sliding member 32 to be better limited when sliding in the slide groove 33, preventing it from deviating during sliding.

[0039] A hanging hole 38 is provided through the front of the slider 32 near the top. The inner walls of the hanging hole 38 are rounded and chamfered on both sides. The hanging hole 38 is used to hook the slider 32 to slide. This design allows the operator to push the locking piece 323 back into the movable cavity 322 through the L-shaped pin, and then lock one end of the L-shaped pin into the hanging hole 38 again to pull the slider 32 upward, making it more convenient to pull up the slider 32.

[0040] Please see Figure 1 and Figure 5 It should be noted that threaded holes 21 for fixing are provided through the four corners of the mounting plate 2. The four corners of the meter body 1 near the mounting plate 2 are fixedly connected with mating blocks 11. The mounting plate 2 has mating slots 22 at the corresponding positions of the mating blocks 11. The mating blocks 11 and mating slots 22 are matched in size. The mounting plate 2 is installed and fixed to the wall or the distribution cabinet through the threaded holes 21 and screws or expansion bolts. The mating blocks 11 and mating slots 22 can be set as magnetic attraction kits that attract each other, or they can be snapped together by interference fit, so that the force points of the meter body 1 are more stable and even after installation, making the installation of the meter body 1 more stable.

[0041] Mounting plate 2 is fixedly connected to the center position between guide rails 31 with plug block 23. The meter body 1 is fixedly connected to the side of mounting plate 2 with fixing plate 12. Plug sleeve 13 is fixedly connected to fixing plate 12. The meter body 1 is connected to mounting plate 2 through plug sleeve 13 and plug block 23. After mounting plate 2 is fixed, plug sleeve 13 on the back of meter body 1 is aligned with plug block 23 on mounting plate 2 for connection, so that plug sleeve 13 is fitted on the outer surface of plug block 23, and the second socket 231 and first socket 131 on plug block 23 and plug sleeve 13 are aligned.

[0042] After the plug-in block 23 and the plug-in sleeve 13 are connected, a first insertion hole 131 and a second insertion hole 231 are opened in the vertical direction to penetrate the plug-in block 23 and the plug-in sleeve 13. A limiting plate 35 is inserted into the first insertion hole 131 and the second insertion hole 231. One side of the limiting plate 35 is connected and fixed to the sliding member 32 through the connecting block 34. When the plug-in sleeve 13 and the plug-in block 23 are connected, the sliding member 32 is slid down, which drives the connecting block 34 and the limiting plate 35 to move down at the same time, so that the limiting plate 35 is inserted into the first insertion hole 131 and the second insertion hole 231 on the plug-in sleeve 13 and the plug-in block 23, thereby realizing the insertion and fixing of the plug-in block 23 and the plug-in sleeve 13 and preventing the plug-in sleeve 13 from detaching from the plug-in block 23.

[0043] Before the slider 32 moves down, the locking member 323 on the second locking block 321 needs to be pressed into the movable cavity 322, so that the locking member 323 is in the installation position 4. At this time, as the slider 32 moves down, it will drive the second locking blocks 321 on both sides to move down and engage with the first locking block 311. At this time, the position of the locking member 323 corresponds to the position of the locking hole 312. Attracted by the magnetic force of the magnetic block 324 and the magnetic sheet, the locking member 323 pressed into the movable cavity 322 will be sucked into the locking hole 312, so that the locking member 323 moves to the locking position 41, thus locking the slider 32.

[0044] This utility model also provides an electricity meter, including a detachable meter fixing structure.

[0045] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
