[0002] A meter box is a housing used to fix and install electrical instruments such as meters and current transformers, providing them with protection and insulation. A pluggable meter box is a specially designed meter box that allows meters to be installed and removed by plugging and unplugging, simplifying the installation and replacement process and improving work efficiency and safety.

[0003] Currently, pluggable meter boxes on the market simplify the installation and replacement process of meters through a series of standardized interfaces and guide rails, enabling operators to quickly and accurately plug and unplug meters, thereby improving work efficiency. However, because they fail to fully consider the needs of meters of different sizes, they cannot provide effective fixing solutions when faced with meters of various sizes. This results in a lack of flexibility and adjustability in the meter boxes, making it impossible to ensure the stable installation of meters, thus limiting the versatility and wide applicability of the meter boxes. Utility Model Content

[0004] The purpose of this utility model is to provide a pluggable meter box that can fix meters of different sizes, improve the versatility and wide applicability of the meter box, meet diverse meter installation needs, simplify the meter replacement process, reduce the difficulty of operation, and improve work efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A pluggable meter box includes a meter box body, with multiple sets of slots fixedly connected to the inner wall of the meter box body. Multiple connecting plates are installed on the inner side of the meter box body. Each connecting plate has a plug block fixedly connected to one of its four corners near the slot. One side of each plug block is inserted into the slot. A clamping assembly is provided on the connecting plate.

[0007] Preferably, the clamping assembly includes a sliding groove formed on the side of the connecting plate away from the insert block. Multiple T-shaped grooves are formed within the sliding groove. A first clamping plate and a second clamping plate are respectively installed on both sides of the connecting plate. A first gear is rotatably connected within the sliding groove. A rack is meshed with the top and bottom of the first gear, and one side of the rack is slidably connected within the T-shaped groove. One rack is fixedly connected to the bottom of one side of the first clamping plate, and the other rack is fixedly connected to the top of one side of the second clamping plate. A strip plate is attached to the side of the two racks away from the first gear, and one side of the strip plate is slidably connected within the T-shaped groove. One end of one strip plate is fixedly connected to the top of one side of the first clamping plate, and one end of the other strip plate is fixedly connected to the bottom of one side of the second clamping plate. A second gear is rotatably connected to the end of the connecting plate away from the sliding groove. A handle is installed on one side of the second gear, and a fixing device is provided on the top of the second gear.

[0008] Preferably, the fixing device includes an N-shaped plate fixedly mounted on the side of the connecting plate near the top of the second gear, the N-shaped plate being internally threaded with a threaded rod, the bottom of the threaded rod being rotatably connected to a toothed plate, and the bottom of the toothed plate being meshed with the top of the second gear.

[0009] Preferably, the first clamping plate and the second clamping plate have circular grooves on the top and bottom of the side away from the first gear. Two L-shaped plates are installed on the side of the first clamping plate and the second clamping plate away from the first gear. A spring is fixedly connected to the side of the L-shaped plate that is close to the first clamping plate and the second clamping plate. The end of the spring away from the L-shaped plate is fixedly connected in the circular groove.

[0010] Preferably, an L-shaped block is fixedly connected to the bottom of one side of the first clamping plate and the second clamping plate, and the L-shaped block has an L-shaped structure.

[0011] Preferably, the bottom of the meter box body near the connecting plate is equipped with a wire groove, the bottom of the meter box body is provided with multiple round holes, a moisture-absorbing plate is inserted into the bottom of the inner cavity of the meter box body, and multiple wire passage holes are installed on one side of the inner cavity of the meter box body.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a pluggable meter box for installing an electricity meter. By incorporating a clamping assembly, when the meter needs to be clamped, rotating the second gear via a handle causes the first gear to rotate within a sliding groove. This rotation, in turn, causes the racks and strip plates on both sides to slide in opposite directions within T-slots. This facilitates the adjustment of the relative positions of the first and second clamping plates via the racks, enabling them to clamp the meter. Subsequently, manually rotating the threaded rod moves the rack plate downwards, bringing it into close contact with the top of the second gear, thus clamping the second gear... Sufficient friction is generated between the toothed plate and the connecting plate to prevent the second gear from rotating, so that meters of different sizes can be clamped onto the connecting plate by the first and second clamps. When it is necessary to remove the meter, the first and second clamps are moved in opposite directions by turning the handle until the meter is released, thus making the installation and removal of the meter simple and quick. This device can fix meters of different sizes, improve the versatility and wide applicability of the meter box, meet diverse meter installation needs, simplify the meter replacement process, reduce the difficulty of operation, and improve work efficiency.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1 one Figure 4 As shown, a pluggable meter box includes a meter box body 1. Multiple sets of slots 2 are fixedly connected to the inner wall of the meter box body 1. Multiple connecting plates 3 are installed on the inner side of the meter box body 1. Each connecting plate 3 has four corners fixedly connected to plugs 4 near the slots 2. One side of each plug 4 is inserted into the slot 2. Clamping components are provided on the connecting plates 3.

[0022] The meter box body 1 is used to install and protect the electricity meter, effectively protecting the internal meter equipment from damage by the external environment. The connecting plate 3 is inserted into the slot 2 via the plug 4 for fixed installation of the electricity meter, making the installation and removal of the electricity meter more convenient. The plug 4 is shaped and sized to match the slot 2. The holding component can accommodate electricity meters of different sizes and clamp and fix them. When it is necessary to install the electricity meter into the meter box body 1, simply clamp the electricity meter onto the connecting plate 3 via the clamping component, then align the plug 4 on the connecting plate 3 with the slot 2 and insert it. The installation process is simple and quick, and the plug-in installation method also facilitates the removal and maintenance of the electricity meter, improving work efficiency.

[0023] like Figure 3 and Figure 4 As shown, the clamping assembly includes a sliding groove 5 on the side of the connecting plate 3 away from the insert block 4. Multiple T-shaped grooves 6 are formed within the sliding groove 5. A first clamping plate 7 and a second clamping plate 8 are respectively installed on both sides of the connecting plate 3. A first gear 9 is rotatably connected within the sliding groove 5. A rack 10 is meshed with the top and bottom of the first gear 9, and one side of the rack 10 is slidably connected within the T-shaped groove 6. One rack 10 is fixedly connected to the bottom of one side of the first clamping plate 7, and the other rack 10 is fixedly connected to the top of one side of the second clamping plate 8. A strip plate 11 is attached to the side of the two racks 10 away from the first gear 9, and one side of the strip plate 11 is slidably connected within the T-shaped groove 6. One end of one strip plate 11 is fixedly connected to the top of one side of the first clamping plate 7, and one end of the other strip plate 11 is fixedly connected to the bottom of one side of the second clamping plate 8. A second gear 12 is rotatably connected to the end of the connecting plate 3 away from the sliding groove 5, and one side of the second gear 12 is fixedly connected to the first gear 9. A handle is installed on one side of the second gear 12, and a fixing device is provided on the top of the second gear 12.

[0024] Specifically, by rotating the handle, the second gear 12 is fixedly connected to the first gear 9. The rotation of the second gear 12 will drive the first gear 9 to rotate within the sliding groove 5. The rotation of the first gear 9 will then drive the racks 10 and strip plates 11 on both sides to slide in opposite directions within the T-groove 6. This will cause the first clamping plate 7 and the second clamping plate 8 to adjust their relative positions via the racks 10, facilitating relative or opposite movements of the first clamping plate 7 and the second clamping plate 8. When it is necessary to clamp the meter, by rotating the handle, the first clamping plate 7 and the second clamping plate 8 will move relative to each other until the meter is tightly clamped between the first clamping plate 7 and the second clamping plate 8. The positions of the first clamping plate 7 and the second clamping plate 8 will be fixed by the fixing device to facilitate clamping meters of different sizes onto the connecting plate 3. Conversely, when it is necessary to disassemble the meter, by rotating the handle, the first clamping plate 7 and the second clamping plate 8 will move in opposite directions until the meter is released. This makes the installation and disassembly of the meter simple and quick, improving work efficiency.

[0025] like Figure 3 As shown, the fixing device includes an N-shaped plate 13 fixedly mounted on the side of the connecting plate 3 near the top of the second gear 12. The N-shaped plate 13 is internally threaded with a threaded rod 14. The bottom of the threaded rod 14 is rotatably connected to a toothed plate 15, and the bottom of the toothed plate 15 is engaged with the top of the second gear 12.

[0026] The first clamping plate 7 and the second clamping plate 8 are clamped on both sides of the meter by rotating the second gear 12 with the handle. The N-shaped plate 13 serves as a fixed fulcrum, allowing the threaded rod 14 to rotate smoothly and drive the toothed plate 15 to move downward until the toothed plate 15 is in close contact with the top of the second gear 12 and generates sufficient friction. This effectively prevents the second gear 12 from rotating unintentionally, so as to fix the first clamping plate 7 and the second clamping plate 8 in the required position. This ensures that the meter is safely and stably clamped on the connecting plate 3, thereby ensuring that the clamping assembly remains stable after the meter is fixed and effectively preventing the meter from loosening.

[0027] like Figure 4 As shown, the top and bottom of the first clamping plate 7 and the second clamping plate 8 away from the first gear 9 are provided with circular grooves 16. Two L-shaped plates 17 are installed on the side of the first clamping plate 7 and the second clamping plate 8 away from the first gear 9. A spring 18 is fixedly connected to the side of the L-shaped plate 17 that is close to the first clamping plate 7 and the second clamping plate 8. The end of the spring 18 away from the L-shaped plate 17 is fixedly connected in the circular groove 16.

[0028] Specifically, after the meter is clamped by the clamping assembly, the L-shaped plate 17 is manually stretched. The stretching of the spring 18 pulls the L-shaped plates 17 on both sides of the meter towards both sides until the spring 18 is in contact with one side of the meter. This makes the L-shaped plate 17 fit tightly against both sides of the meter, enhancing the clamping assembly's fixing effect on the meter. The L-shaped plate 17 further limits and fixes the meter. The design of the spring 18 allows the L-shaped plate 17 to automatically reset when not in use, facilitating the next meter installation operation.

[0029] like Figure 1 As shown, an L-shaped block 19 is fixedly connected to the bottom of one side of the first clamping plate 7 and the second clamping plate 8. The L-shaped block 19 has an L-shaped structure.

[0030] The L-shaped block 19 has an L-shaped structure, which can effectively increase the contact area between the clamping component and the bottom of the meter box, and improve the stability of the clamping component. The L-shaped block 19 can also serve as a support point, further enhancing the clamping force of the clamping component on the meter and ensuring the meter's firmness after installation.

[0031] like Figure 1 As shown, wire grooves 20 are installed on the bottom of the meter box body 1 near the connecting plate 3. Multiple round holes 21 are opened on the bottom of the meter box body 1. A moisture-absorbing plate 22 is inserted into the bottom of the inner cavity of the meter box body 1. Multiple wire passage holes 23 are installed on one side of the inner cavity of the meter box body 1.

[0032] Specifically, the wire trough 20 is used to clamp and fix the wires at the bottom of the meter, so that the meter's wires are neatly arranged, avoiding the safety hazards caused by messy wiring, and the wires are transported to the outside of the box through the wire hole 23; the design of the round hole 21 is used to ventilate and dissipate heat in the inner cavity of the meter box body 1, effectively preventing problems such as circuit aging or short circuits caused by humid or high-temperature environments inside the meter box body 1, improving the service life and safety of the meter box; the moisture-absorbing plate 22 is used in conjunction with the round hole 21 to keep the inside of the meter box body 1 dry, effectively removing moisture inside the box, and further preventing the circuit from being damaged by a humid environment; when outside air enters the inner cavity of the meter box body 1 through the round hole 21, the moisture-absorbing plate 22 can absorb the moisture in the air, keeping the environment inside the box dry, ensuring that the meter and its wiring operate in good working condition, thereby improving the safety and reliability of the entire meter box.

[0033] The working principle of this utility model is as follows: First, the second gear 12 is rotated by the handle. The rotation of the second gear 12 drives the first gear 9 to rotate in the sliding groove 5. The rotation of the first gear 9 then drives the racks 10 and strip plates 11 on both sides to slide in opposite directions in the T-shaped groove 6, so that the first clamping plate 7 and the second clamping plate 8 produce relative movement, and the meter is clamped between the first clamping plate 7 and the second clamping plate 8. Next, the threaded rod 14 is manually rotated until the toothed plate 15 moves downward and makes tight contact with the top of the second gear 12. Sufficient friction is generated between the second gear 12 and the toothed plate 15 to prevent the second gear 12 from rotating, and the meter is firmly clamped on the connecting plate 3. Finally, the plug 4 on the connecting plate 3 is inserted into the slot 2 in the meter box body 1, thereby completing the fixing of the meter.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
