Description

Technical Field

[0001] This utility model relates to the field of power distribution technology, specifically to a combined meter box. Background Technology

[0002] In power infrastructure, modular meter boxes play a crucial role in centralized meter management. However, their fixed internal structure limits the number of meters they can accommodate from the outset. When electricity demand increases slightly, requiring the addition of a few meters, the lack of scalability of the existing box necessitates replacing the entire box. In this situation, the cost of purchasing the new box and the labor costs for dismantling and installation are extremely low compared to the actual need for a few additional meters, resulting in resource waste and an unnecessary economic burden on power management.

[0003] Patent publication number CN222618697U discloses a combined electricity meter box, including an inlet box module, a busbar box module, an electricity meter box module, an outlet box module, and a line box module. The inlet box module, busbar box module, electricity meter box module, outlet box module, and line box module are flexibly assembled and detachably connected by connecting components. Adjacent inlet box modules, busbar box modules, electricity meter box modules, outlet box modules, and line box modules are connected by knock-out inlet and outlet components. The electricity meter box module includes several flexibly combined electricity meter boxes, which are used to install electricity meters of different models. Adjacent electricity meter boxes are connected, and the electricity meter boxes located at the edge are connected to the line box module.

[0004] The aforementioned device has multiple boxes inside for placing electricity meters. However, the number of electricity meters that can be installed in each box is fixed. This leads to the problem that when more electricity meters are needed, a new box needs to be replaced. If the number of electricity meters to be added is small, the cost of replacing the box is too high and the economic efficiency is low. Utility Model Content

[0005] The purpose of this utility model is to provide a modular meter box to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A modular meter box includes a meter box, with a partition fixedly connected inside the meter box, the partition dividing the inside of the meter box into three chambers, with a meter, a main power switch and a user power switch respectively fixedly connected to the three chambers inside the meter box, and a protective door hinged to the front of the meter box;

[0008] It also includes a meter position adjustment mechanism, an expansion mechanism, a fixing mechanism, and a quick connection mechanism;

[0009] The meter position adjustment mechanism is used to fix the meter and adjust the distance between adjacent meters;

[0010] The expansion mechanism is located on the left side of the meter box and is used to expand the meter box.

[0011] The fixing mechanism is located on the back of the meter box and is used to fix the longitudinal position of the expansion mechanism.

[0012] The quick-connect mechanism is located on the side of the meter box and is used to fix the lateral position of the expansion mechanism.

[0013] A further improvement of this utility model is that: the meter position adjustment mechanism includes a fixed guide rail and a fixed lug. The fixed guide rail is fixedly connected to the inner wall surface of the meter box. The fixed guide rail is arranged in a linear array. Limiting holes are opened on the surface of the fixed guide rail. The fixed lug is hinged to the left and right sides of the meter. A fixing bolt is inserted into the inside of the fixing lug. The fixing bolt is threaded into the inside of the limiting hole. The meter is fixedly connected to the fixed guide rail through the fixing lug and the fixing bolt.

[0014] A further improvement of the present invention is that the fixing mechanism includes a fixing block and a sliding groove, the fixing block and the sliding groove are fixedly connected to the back of the meter box, a connecting slide rail is slidably connected inside the sliding groove, and bolt holes are provided on the surface of the bolt holes.

[0015] A further improvement of the present invention is that: the expansion mechanism includes a fixed slide groove, the fixed slide groove is slidably connected to the surface of the connecting slide rail, an expansion meter box is fixedly connected to the front of the fixed slide groove, an expansion fixed guide rail is fixedly connected inside the expansion meter box, an expansion meter is fixedly connected to the front of the expansion fixed guide rail, an expansion gate is fixedly connected to the bottom of the inner wall of the expansion meter box, and a second protective door is hinged to the front of the expansion meter box.

[0016] A further improvement of this utility model is that: a plug is fixedly connected to the right side of the expansion meter box, the plug is electrically connected to the expansion meter, a slot is fixedly connected to the left side of the meter box, the slot is electrically connected to the main power switch, and a groove for the plug is provided inside the slot.

[0017] A further improvement of this utility model is that the quick connection mechanism includes a limiting block, which is inserted into the side of the expansion meter box. The limiting block extends through the side of the expansion meter box and the meter box into the interior of the meter box. A connecting column is fixedly connected to the right side of the limiting block. A loading and unloading groove is provided on the side of the connecting column. A connector is inserted into the outside of the connecting column. The connector is located inside the meter box. A cam block is rotatably connected inside the connector. The diameter of the cam block at its maximum point is slightly larger than the diameter of the connecting column. A pressure rod is fixedly connected to the surface of the cam block.

[0018] A further improvement of this utility model is that the second protective door and the first protective door are made of transparent material.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model provides a modular meter box. By installing the meter box on the wall, during use, as the number of residents increases, the internal space of the meter box is insufficient to accommodate more meters. Replacing it with a larger meter box would be too costly. This device expands the meter box quickly by unfolding and fixing the fixing mechanism, then inserting the expansion mechanism into the fixing mechanism, and fixing the expansion mechanism to the meter box through a quick-connect mechanism. The original meter box can still be used, thereby reducing the cost of expansion. When the number of residents decreases, the expansion mechanism can be quickly removed by disassembling the quick-connect mechanism to avoid wasting space. The meter position adjustment mechanism can adjust the distance between adjacent meters during maintenance, thus facilitating maintenance.

[0021] 2. This utility model provides a combined meter box. The meter box is fixed to the wall by a fixing block. The connecting slide rail is pulled out and fixed to the wall. Then, the expansion mechanism is taken out, the fixing slide groove is aligned with the connecting slide rail, and inserted into the inside of the connecting slide rail, thereby fixing the longitudinal position of the expansion meter box. At the same time, as the expansion meter box and the meter box move closer together, the plug will be inserted into the slot, thereby connecting the circuit. Then, the limiting block is inserted into the side of the expansion meter box, and the connector is inserted into the connecting post. Then, the pressure rod is bent to the right, and the pressure rod drives the cam block to rotate. As the cam block rotates, the diameter of the contact point between the cam block and the connecting post gradually increases, thereby squeezing the connecting post. The squeezing force fixes the limiting block and the connector together, thereby quickly fixing the expansion meter box and the meter box.

[0022] 3. This utility model provides a combined meter box. By leaving a certain margin when wiring the meter to the user's circuit breaker, when the meter needs to be repaired, the fixing bolts on the adjacent meter are unscrewed to release the meter from the fixed guide rail, and then the meter is moved to the side, thus providing a large space for meter repair, so that the problem can be quickly found and repaired.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figure 1-6 As shown, this utility model has the following three specific embodiments.

[0039] Example 1

[0040] This utility model provides a combined meter box, including a meter box 11. A partition 12 is fixedly connected inside the meter box 11, which divides the inside of the meter box 11 into three chambers. A meter 13, a main switch 14 and a user switch 15 are respectively fixedly connected to the three chambers inside the meter box 11. A protective door 16 is hinged to the front of the meter box 11.

[0041] It also includes a meter position adjustment mechanism 2, an expansion mechanism 6, a fixing mechanism 3, and a quick connection mechanism 4;

[0042] The meter position adjustment mechanism 2 is used to fix the meter 13 and adjust the distance between adjacent meters 13;

[0043] The expansion mechanism 6 is located on the left side of the meter box 11 for expanding the meter box 11;

[0044] The fixing mechanism 3 is located on the back of the meter box 11 and is used to fix the longitudinal position of the expansion mechanism 6.

[0045] The quick-connect mechanism 4 is located on the side of the meter box 11 and is used to fix the lateral position of the expansion mechanism 6.

[0046] In this embodiment, as Figure 1As shown, by installing the meter box 11 on the wall, during use, due to the increase in the number of residents, the space inside the meter box 11 is insufficient to accommodate more meters 13. If replacing it with a larger meter box 11 is too costly, this device can quickly expand the meter box 11 by unfolding and fixing the fixing mechanism 3, then inserting the expansion mechanism 6 into the inside of the fixing mechanism 3, and fixing the expansion mechanism 6 to the meter box 11 through the quick connection mechanism 4. The original meter box 11 can still be used, thereby reducing the cost of expansion. When the number of residents decreases, the expansion mechanism 6 can be quickly removed by disassembling the quick connection mechanism 4 to avoid wasting space. The distance between adjacent meters 13 can be adjusted during maintenance by the meter position adjustment mechanism 2, thereby facilitating maintenance.

[0047] Example 2

[0048] The difference from Embodiment 1 is that this embodiment discloses an expansion mechanism 6, a fixing mechanism 3, and a quick-connect mechanism 4.

[0049] Preferably, the fixing mechanism 3 includes a fixing block 31 and a slide 32. The fixing block 31 and the slide 32 are fixedly connected to the back of the meter box 11. A connecting slide rail 33 is slidably connected inside the slide 32. Bolt holes 34 are provided on the surface of the bolt holes 34.

[0050] The expansion mechanism 6 includes a fixed slide 66, which is slidably connected to the surface of the connecting slide rail 33. An expansion meter box 61 is fixedly connected to the front of the fixed slide 66. An expansion fixed guide rail 62 is fixedly connected inside the expansion meter box 61. An expansion meter 63 is fixedly connected to the front of the expansion fixed guide rail 62. An expansion gate 64 is fixedly connected to the bottom of the inner wall of the expansion meter box 61. A second protective door 65 is hinged to the front of the expansion meter box 61.

[0051] A plug 51 is fixedly connected to the right side of the power meter box 61. The plug 51 is electrically connected to the power meter 63. A slot 52 is fixedly connected to the left side of the power meter box 11. The slot 52 is electrically connected to the main power switch 14. The slot 52 has a groove for the plug 51.

[0052] The quick connection mechanism 4 includes a limiting block 41, which is inserted into the side of the expansion meter box 61. The limiting block 41 passes through the side of the expansion meter box 61 and the meter box 11 and extends into the interior of the meter box 11. A connecting post 42 is fixedly connected to the right side of the limiting block 41. A loading and unloading groove 43 is opened on the side of the connecting post 42. A connector 44 is inserted into the outside of the connecting post 42. The connector 44 is located inside the meter box 11. A cam block 45 is rotatably connected inside the connector 44. The diameter of the cam block 45 at its maximum point is slightly larger than the diameter of the connecting post 42. A pressure rod 46 is fixedly connected to the surface of the cam block 45.

[0053] Protective door 2.65 and protective door 1.16 are made of transparent material.

[0054] In this embodiment, as Figure 4-6 As shown, the meter box 11 is fixed to the wall by the fixing block 31. The connecting slide rail 33 is pulled out and fixed to the wall. Then, the expansion mechanism 6 is taken out, the fixing slide groove 66 is aligned with the connecting slide rail 33 and inserted into the inside of the connecting slide rail 33, thereby fixing the longitudinal position of the expansion meter box 61. At the same time as fixing, as the expansion meter box 61 and the meter box 11 move closer to each other, the plug 51 will be inserted into the inside of the slot 52, thereby connecting the circuits. Then, the limiting block 41 is inserted into the side of the expansion meter box 61, and the connector 44 is inserted into the connecting post 42. Then, the pressure rod 46 is bent to the right, and the pressure rod 46 drives the cam block 45 to rotate. As the cam block 45 rotates, the diameter of the contact point between the cam block 45 and the connecting post 42 gradually increases, thereby squeezing the connecting post 42. The squeezing force fixes the limiting block 41 and the connector 44 to each other, thereby quickly fixing the expansion meter box 61 and the meter box 11.

[0055] Example 3

[0056] The difference from Embodiment 2 is that this embodiment discloses a meter position adjustment mechanism 2.

[0057] Preferably, the meter position adjustment mechanism 2 includes a fixed guide rail 21 and a fixed ear 22. The fixed guide rail 21 is fixedly connected to the inner wall surface of the meter box 11. The fixed guide rail 21 is arranged in a linear array. Limiting holes 23 are opened on the surface of the fixed guide rail 21. The fixed ear 22 is hinged to the left and right sides of the meter 13. A fixing bolt 24 is inserted into the inside of the fixing ear 22. The fixing bolt 24 is threaded into the inside of the limiting hole 23. The meter 13 is fixedly connected to the fixed guide rail 21 through the fixing ear 22 and the fixing bolt 24.

[0058] In this embodiment, as Figure 2 and 3 As shown, by leaving a margin when wiring the meter 13 to the user's circuit breaker 15, when the meter 13 needs to be repaired, the fixing bolts 24 on the adjacent meter 13 are unscrewed to release the fixing between the meter 13 and the fixed guide rail 21, and then the meter 13 is moved to one side, thus providing a lot of space for the meter 13 to be repaired, so that the problem can be found and repaired quickly.

[0059] The working principle of this utility model is as follows.

[0060] The meter box 11 is fixed to the wall using the fixing block 31. The connecting slide rail 33 is pulled out and fixed to the wall. Then, the expansion mechanism 6 is taken out, the fixing slide groove 66 is aligned with the connecting slide rail 33, and inserted into the inside of the connecting slide rail 33, thereby fixing the longitudinal position of the expansion meter box 61. At the same time, as the expansion meter box 61 and the meter box 11 move closer to each other, the plug 51 will be inserted into the inside of the slot 52, thereby connecting the circuits. Then, the limiting block 41 is inserted into the side of the expansion meter box 61, and the connector 44 is inserted into the connecting post 42. Then, the pressure rod 46 is bent to the right, and the pressure rod 46 drives the cam block 45 to move. As the cam block 45 rotates, the diameter of the contact point between the cam block 45 and the connecting column 42 gradually increases, thereby squeezing the connecting column 42. The squeezing force fixes the limiting block 41 and the connector 44 together, thus quickly fixing the expansion meter box 61 and the meter box 11. By leaving a certain margin when wiring the meter 13 and the user's circuit breaker 15, when the meter 13 needs to be repaired, the fixing bolts 24 on the adjacent meter 13 are unscrewed to release the fixing between the meter 13 and the fixed guide rail 21, and then the meter 13 is moved to one side, thus providing a lot of space for the repair of the meter 13, so that the problem can be quickly found and repaired.

[0061] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. The selection and detailed description of these embodiments in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
