These modules can be pre-produced and quality-tested in the factory, ensuring quality while greatly simplifying the on-site installation process. Compared to traditional on-site assembly methods, modular assembly can significantly reduce assembly time and workload, improving overall installation efficiency. This is especially important for situations requiring rapid deployment and installation, such as emergency power repairs and temporary power supplies, thus necessitating a modular, rapid assembly structure for the prepaid meter box.

[0003] The modular and rapid assembly structure of the prepaid meter box aims to simplify the installation and assembly process of the prepaid meter box, and improve installation efficiency and convenience. In the past, the prepaid meter box was limited in terms of expandability and flexibility. Moreover, if a component failed, the entire box needed to be disassembled and inspected, which was not only time-consuming and labor-intensive, but also could damage other components due to improper operation during the disassembly process. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a modular quick assembly structure for the expense control meter box, which aims to improve the limitation of the expense control meter box in terms of expandability and flexibility. Furthermore, if a component fails, the entire meter box needs to be disassembled and inspected, which is not only time-consuming and labor-intensive, but may also cause damage to other components due to improper operation during the disassembly process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular quick-assembly structure for a prepaid meter box, comprising a fixed plate, a fixed cylinder fixedly connected inside the fixed plate, a movable column slidably connected inside the fixed cylinder, a first limiting plate fixedly connected to the outer wall of the movable column, a movable block slidably connected to the outer wall of the first limiting plate, a spring fixedly connected to the outer wall of the movable block, a second limiting plate fixedly connected to the outer wall of the movable block, a limiting column rotatably connected inside the second limiting plate, both ends of the limiting column being fixedly connected to the inside of the fixed cylinder, a limiting block slidably connected to the outer wall of the second limiting plate, a power module fixedly connected to the outer wall of the limiting block, and the outer wall of the limiting block slidably connected to the inside of the fixed plate and the upper surface of the fixed cylinder.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a modular quick-assembly structure for a prepaid meter box, comprising a fixed plate 1, a fixed cylinder 2 fixedly connected inside the fixed plate 1, a movable column 3 slidably connected inside the fixed cylinder 2, a first limiting piece 4 fixedly connected to the outer wall of the movable column 3, a movable block 5 slidably connected to the outer wall of the first limiting piece 4, a spring 6 fixedly connected to the outer wall of the movable block 5, a second limiting piece 7 fixedly connected to the outer wall of the movable block 5, a limiting column 8 rotatably connected inside the second limiting piece 7, both ends of the limiting column 8 being fixedly connected to the inside of the fixed cylinder 2, a limiting block 9 slidably connected to the outer wall of the second limiting piece 7, a power module 10 fixedly connected to the outer wall of the limiting block 9, and the outer wall of the limiting block 9 slidably connected to the inside of the fixed plate 1 and the upper surface of the fixed cylinder 2. A meter box assembly is provided on the outer wall of the fixed plate 1, the meter box assembly being used to protect the internal equipment from the influence of the external environment.

[0024] Specifically, movable columns 3 are provided on both sides of the fixed cylinder 2. By pressing the movable columns 3 on both sides simultaneously, the first limiting plate 4 is moved. The first limiting plates 4 on both sides simultaneously drive the movable block 5 to compress the spring 6. The movable block 5 drives the second limiting plate 7 to rotate on the outer wall of the limiting column 8. The fixed cylinder 2 provides fixed support for the limiting column 8, and the limiting column 8 limits the second limiting plate 7. The second limiting plate 7 slides inside the limiting block 9. The limiting block 9 has a limiting groove inside, which limits the second limiting plate 7. This limits and fixes the limiting block 9, and thus limits and fixes the power module 10.

[0025] Reference Figure 1 and Figure 4 The metering box assembly includes a metering box body 11. The inner wall of the metering box body 11 is fixedly connected to the outer wall of the fixing plate 1. A door 12 is rotatably connected to the outer wall of the metering box body 11. A handle 13 is fixedly connected to the outer wall of the door 12. A first fixing plate 14 is fixedly connected to the outer wall of the metering box body 11. A connecting plate 15 is rotatably connected to the outer wall of the first fixing plate 14. A hydraulic cylinder 16 is fixedly connected to the outer wall of the connecting plate 15. A connecting block 17 is fixedly connected to the output end of the hydraulic cylinder 16. A fixing shaft 18 is fixedly connected inside the connecting block 17. An arc-shaped block 19 is rotatably connected to the outer wall of the fixing shaft 18. A pressing block 20 is fixedly connected to the outer wall of the arc-shaped block 19. The outer wall of the pressing block 20 is slidably connected to the outer wall of the door 12.

[0026] Specifically, by driving the handle 13, the door 12 is rotated on the outer wall of the metering box body 11. The outer wall of the door 12 is provided with a sealing strip. When the pressing block 20 presses the door 12, it seals the metering box body 11. The hydraulic cylinder 16 drives the connecting block 17, which in turn drives the fixed shaft 18 to move. The fixed shaft 18 drives the arc-shaped block 19, which in turn drives the pressing block 20 to press and fix the door 12. When the hydraulic cylinder 16 is activated, it drives the connecting piece 15 to rotate on the outer wall of the first fixed piece 14. The metering box body 11 provides fixed support for the first fixed piece 14. The first fixed piece 14 then limits the connecting piece 15, which in turn limits the hydraulic cylinder 16.

[0027] Reference Figure 4 The inner part of the arc-shaped block 19 is rotatably connected to a limiting rod 21, and the outer wall of the limiting rod 21 is fixedly connected to a second fixing plate 22. The outer wall of the second fixing plate 22 is fixedly connected to the outer wall of the metering box body 11.

[0028] Specifically, the arc-shaped block 19 moves and rotates on the outer wall of the limiting rod 21, thereby limiting the arc-shaped block 19 through the limiting rod 21, fixing the limiting rod 21 through the second fixing plate 22, and fixing the second fixing plate 22 through the metering box body 11.

[0029] Working principle: When this structure is needed, pressing the movable column 3 slides inside the fixed cylinder 2, thereby moving the first limiting plate 4. The first limiting plate 4 moves the movable block 5, which in turn compresses the spring 6. The movable block 5 moves the second limiting plate 7 to rotate on the outer wall of the limiting column 8, and then the second limiting plate 7 slides inside the limiting block 9, thereby limiting and fixing the limiting block 9, and thus limiting and fixing the power module 10. By holding the handle 13, the box door 12 rotates on the outer wall of the metering box body 11. At the same time, the hydraulic cylinder 16 is activated, which moves the connecting block 17, which in turn moves the fixed shaft 18. The fixed shaft 18 moves the arc-shaped block 19, which in turn moves the pressing block 20 to press against the box door 12. 2. Press and fix. While the arc-shaped block 19 moves, it rotates on the outer wall of the limiting rod 21 to limit it. At the same time, the hydraulic cylinder 16 starts and drives the connecting piece 15 to rotate on the outer wall of the first fixed piece 14. This structure can be flexibly configured according to actual needs to adapt to different application scenarios and customer needs. When a module fails, only the module needs to be replaced or repaired. There is no need to disassemble and reassemble the entire fee control meter box, which reduces maintenance costs and time. It can also ensure that the inside of the fee control meter box is protected from interference and damage from the external environment, and prevent dust, moisture, insects and other things from entering the box. This protects the internal metering equipment and electrical components from pollution and corrosion, and helps to improve the operational stability and service life of the equipment.
