Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to a transportable electricity metering box. Background Technology

[0002] In the construction and operation and maintenance system of smart grids, electricity metering boxes are core terminal equipment for realizing electricity data collection, metering monitoring, and electricity management. Their installation form and structural design directly affect the stability of grid operation and the convenience of operation and maintenance. Wall-mounted electricity metering boxes are widely used in residential buildings, commercial complexes, and industrial plants due to their advantages such as small space occupation, convenient installation, and strong adaptability. These metering boxes need to meet the requirements of long-term stable operation in complex outdoor or indoor environments, while also taking into account the ease of operation for later inspection and maintenance. They are an important part of the standardized and regulated construction of smart grid terminal facilities.

[0003] The typical structure of existing wall-mounted electricity metering boxes mainly includes a box body and a door rotatably connected to the front of the box. To ensure heat dissipation during equipment operation, ventilation openings are provided on both the left and right sides of the box body. For cable access and wiring management, a dedicated wiring port is provided on the bottom of the box body. In actual installation, construction personnel rigidly fix the back of the box body to the wall using expansion screws. At the same time, installation specifications must be strictly followed to ensure that the bottom of the box body maintains the specified safe height from the ground. This prevents damage to the equipment from ground moisture, water accumulation, and external impacts, ensuring that the installation accuracy and operational safety of the metering box meet the operation and maintenance standards of the smart grid.

[0004] During routine inspections, troubleshooting, or component replacements of wall-mounted electricity metering boxes, workers generate a large amount of debris, such as cable cutting scraps, small metal parts like screws, aging seals, and disassembled used components. Workers typically discard this debris or waste directly on the ground. However, this not only creates a messy work environment but also increases the difficulty and time cost of subsequent cleanup, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an easily transportable electricity metering box, which solves the problem in the above-mentioned related technologies that when wall-mounted electricity metering boxes are operated and maintained, the direct disposal of debris can easily cause clutter in the work area, increasing the difficulty of cleaning and time costs.

[0006] The electricity metering box that is easy to transport provided in this application adopts the following technical solution: An easily transportable electricity metering box includes a box body and a door rotatably mounted on the front side of the box body. The left and right sides of the box body have heat dissipation vents, and the bottom surface has a wiring port. Two vertically downward connecting rods are detachably mounted on the rear edge of the bottom surface of the box body. The lower end of the connecting rods is detachably mounted with a horizontally forward-facing receiving rod. A flexible collection bag with an upward-facing opening is provided below the box body. Fasteners for fixing the upper edge of the opening of the flexible collection bag are provided on the top surface of the receiving rod.

[0007] By adopting the above technical solutions, the flexible collection bags can temporarily and systematically collect cable scraps, screws, and discarded components during subsequent maintenance operations. This avoids the problem of cluttered work areas caused by direct disposal of debris, significantly reducing the difficulty and time cost of subsequent cleanup and improving the efficiency and standardization of maintenance operations. Meanwhile, the detachable design of the connecting rods and receiving rods facilitates later maintenance and replacement without occupying additional installation space. This adapts to the installation needs of wall-mounted metering boxes in various scenarios, ensuring a balance between equipment operational stability and ease of maintenance.

[0008] Optionally, the fastener includes a fastening rod with one end rotatably connected to the rear edge of the top surface of the receiving rod, and a torsion spring disposed at the junction of the fastening rod and the receiving rod, the torsion spring being used to keep the fastening rod and the receiving rod elastically pressed against each other.

[0009] By adopting the above technical solution, the torsion spring drives the fastening rod and the receiving rod to elastically clamp together, which can quickly clamp the opening edge of the flexible collection bag. The fixing operation is convenient and stable, and it can prevent the collection bag from falling off when storing debris. At the same time, the rotating connection structure facilitates opening and closing operations, adapts to the edge of collection bags of different thicknesses, improves the efficiency of collection bag assembly and disassembly, and ensures smooth operation and maintenance of storage.

[0010] Optionally, the upper end of the connecting rod is rotatably connected to the bottom surface of the box, and the lower end is rotatably connected to the receiving rod. The rotation surfaces of the connecting rod and the receiving rod are parallel to the left and right sides of the box. A vertically downward limiting rod is fixed at the lower edge of the end of the receiving rod, and the back of the limiting rod is flush with the back of the box.

[0011] By adopting the above technical solution, the rotating connection between the connecting rod and the receiving rod enables flexible switching between multiple states, adapting to different scenarios such as storage and movement. The limiting rod can precisely limit the receiving rod, keeping it stably horizontal and forward-facing, ensuring the flexible collection bag is firmly supported. The structural design is simple and highly reliable, improving the flexibility and stability of the equipment.

[0012] Optionally, a number of movable wheels are fixed on the side of the fastening rod away from the receiving rod, and a traction handle is rotatably connected on the side of the two limiting rods that are close to each other. The traction handle is parallel to the rotation surface of the connecting rod. The connecting rod and the receiving rod can rotate to a horizontal state that abuts against the bottom surface of the box. At this time, the movable wheels are on the side of the fastening rod facing the ground. The traction handle is used to drive the box to move a short distance using the movable wheels.

[0013] By adopting the above technical solution, utilizing the movable wheels on the fastening rod and the traction handle on the limiting rod, combined with the rotation function of the connecting rod and the receiving rod, the mobile component can be flexibly stored and deployed. When no movement is needed, the component can be stored flush with the bottom of the housing, without affecting normal installation and maintenance; when short-distance movement is required, simply rotate the connecting rod and the receiving rod to a horizontal position so that the movable wheels touch the ground, and the staff can easily move the housing using the traction handle, without the need for additional handling equipment, significantly reducing labor costs, improving the convenience of equipment transfer, and adapting to the needs of short-distance movement scenarios such as construction sites and maintenance adjustments.

[0014] Optionally, the traction handle is an elastic structure that can be elastically extended, and a fixing block is fixedly provided at the rear edge of the bottom surface of the box; the traction handle can be rotated to a vertically upward state when the connecting rod is in a vertically downward state, and a fixing slot for the fixing block to be inserted is provided on the top surface of the traction handle at this time.

[0015] By adopting the above technical solution, and utilizing the elastic telescopic characteristics of the traction handle and the snap-fit ​​cooperation of the fixing block and fixing slot, the positions of the connecting rod and the receiving rod can be quickly locked during maintenance, preventing component shaking and displacement, and ensuring the stable support of the flexible collection bag. The ingenious structural design and convenient operation require no additional tools, improving the safety and efficiency of maintenance work.

[0016] Optionally, the fixing block has a first inclined surface at its outer edge away from the housing.

[0017] By adopting the above technical solution, the first inclined surface of the outer edge of the fixed plug can guide it to smoothly snap into the fixed slot, reduce the resistance of the snap-fit ​​operation, realize the quick locking of the traction handle state, and improve the convenience of fixing the parts during maintenance operations.

[0018] Optionally, the outer peripheries of the two receiving rods, which are far from the limiting rod, are rotatably connected to each other, and are provided with elastic fixing rods with elastic elongation properties. The end faces of the elastic fixing rods that are far from each other are fixed with fixing protrusions and fixing grooves. When the connecting rod is in a vertical downward state, the two elastic fixing rods can rotate to a coaxial abutting state, and the fixing protrusion on one of the two elastic fixing rods is inserted into the fixing groove on the other elastic fixing rod.

[0019] By adopting the above technical solution, a rotatable and elastically extendable fixing rod is set at the end of the receiving rod. Combined with the snap-fit ​​structure of the fixing protrusion and fixing groove, the two elastic fixing rods can be rotated to coaxial contact and locked during maintenance. This structure provides stable bottom support for the flexible collection bag, preventing it from collapsing or falling off due to excessive weight of collected items. Simultaneously, the telescopic performance of the elastic fixing rod can adapt to collection bags of different sizes, improving the structure's versatility. The entire locking process requires no additional tools, is convenient and efficient, and further ensures the orderly conduct of maintenance and repair work.

[0020] Optionally, a second inclined surface is provided on the outer edge of the side of the fixing protrusion away from the elastic fixing rod.

[0021] By adopting the above technical solution, the second inclined surface of the outer edge of the fixed protrusion can guide it to smoothly insert into the fixed groove, reduce the clamping resistance, realize the rapid coaxial docking of the elastic fixing rod, and improve the assembly efficiency of the collection bag support structure during maintenance.

[0022] Optionally, a first slot is provided on both the left and right sides of the fixing block; the two elastic fixing rods can rotate to a coaxial state when the moving wheel is facing down, and the fixing protrusion is inserted into the corresponding first slot at this time.

[0023] By adopting the above technical solution, after the elastic fixing rod is coaxially connected, the locking cooperation between the fixing protrusion and the first slot of the fixing plug can further lock the relative position of the connecting rod and the receiving rod during short-distance movement of the box, avoid the shaking and displacement of the parts during the movement, improve the structural stability during the movement, and no additional tools are required, making the operation convenient and efficient.

[0024] Optionally, when the connecting rod is rotated to a horizontal state and the receiving rod is rotated to a vertical downward state, the traction handle can be rotated to a tilted backward state. At this time, a second slot is provided on the outer side of the traction handle facing forward. The two elastic fixing rods can be rotated to a parallel side-by-side state. The fixing protrusion can be inserted into the second slot to fix the state of the traction handle.

[0025] By adopting the above technical solution, and through the engaging engagement of the elastic fixing rod and the second slot of the traction handle, the traction handle can be securely locked in a tilted, rearward position during normal installation of the metering box. This structure allows the traction handle to provide diagonal support to the box body, effectively dispersing the stress on the bottom of the box and resisting the risk of shaking caused by minor external impacts or wind, significantly improving the installation stability of the box. Furthermore, this locking method requires no additional tools; it can be completed using the elasticity of the fixing rod itself, making it convenient and efficient. The interconnected locking of all components, coupled with a compact design, saves space and is suitable for wall-mounted metering box installation scenarios.

[0026] In summary, this application includes the following beneficial technical effects: In this application, during later maintenance operations, the flexible collection bag can temporarily and systematically collect cable waste, screws, scrap components and other debris, avoiding the problem of messy work areas caused by direct disposal of debris from the source, greatly reducing the difficulty and time cost of subsequent cleaning, and improving the efficiency and standardization of operation and maintenance.

Detailed Implementation

[0029] The present application will be further described in detail below with reference to all the accompanying drawings. Example

[0030] Reference Figure 1 and Figure 2A transportable electricity metering box includes a box body 1 and a door 2 rotatably installed on the front side of the box body 1. The box body 1 has heat dissipation vents 11 on the left and right sides and wiring ports 12 on the bottom surface. Two vertically downward connecting rods 3 are detachably installed at the rear edge of the bottom surface of the box body 1, and a horizontally forward receiving rod 4 is detachably installed at the lower end of the connecting rods 3. The fastener 6 includes a fastening rod 61 with one end rotatably connected to the rear edge of the top surface of the receiving rod 4, and a torsion spring (not shown in the figure) located at the junction of the fastening rod 61 and the receiving rod 4. The torsion spring is used to keep the fastening rod 61 and the receiving rod 4 elastically pressed against each other, thereby clamping the opening edge of the flexible collection bag 5. A flexible collection bag 5 with its opening facing upwards is provided at the bottom of the box body 1, and a fastener 6 is provided on the top surface of the receiving rod 4; during later maintenance, the upper edge of the opening of the flexible collection bag 5 is fixed by the fastener 6, and then the flexible collection bag 5 is used to temporarily store the disassembled or replaced waste parts.

[0031] Reference Figure 2 The upper end of the connecting rod 3 is rotatably connected to the bottom surface of the box 1, and the lower end is rotatably connected to the receiving rod 4. The rotating surfaces of the connecting rod 3 and the receiving rod 4 are parallel to the left and right sides of the box 1. A vertically downward limiting rod 41 is fixed at the lower edge of the end of the receiving rod 4. The back of the limiting rod 41 is flush with the back of the box 1. The limiting rod 41 is used to limit and fix the state of the receiving rod 4, so that the receiving rod 4 remains horizontal and forward.

[0032] Reference Figure 3 Two movable wheels 62 are fixed on the side of the two fastening rods 61 away from the receiving rod 4. A traction handle 7 is rotatably connected on the side of the two limiting rods 41 that are close to each other, and the traction handle 7 is parallel to the rotation surface of the connecting rod 3. When the electricity metering box needs to be moved a short distance, the staff can rotate both the connecting rod 3 and the receiving rod 4 to a horizontal position that is in contact with the bottom surface of the box 1, and the moving wheel 62 is at this time on the side of the fastening rod 61 facing the ground. The staff can then use the traction handle 7 to drive the box 1 to move a short distance using the moving wheel 62.

[0033] Reference Figure 3 , Figure 4 and Figure 5 The traction handle 7 has a fixed slot 71 on its outer periphery, and the traction handle 7 is a conventional elastic telescopic structure with an internal spring that can elastically extend. A fixed plug 13 is fixed at the rear edge of the bottom surface of the box 1, and the fixed plug 13 has a first inclined surface 131 at the outer edge away from the box 1. During later maintenance, when the connecting rod 3 is in a vertical downward position, the staff can turn the traction handle 7 to a vertical upward position. At this time, the fixing slot 71 is located directly below the fixing block 13. With the help of the elasticity of the traction handle 7, the fixing block 13 can be inserted into the fixing slot 71, thereby locking and limiting the state of the connecting rod 3 and the receiving rod 4.

[0034] Reference Figure 6 and Figure 7 Two receiving rods 4 are rotatably connected to each other on their outer periphery, away from the ends of the limiting rod 41. The elastic fixing rod 8 is a conventional telescopic structure with an internal spring, which will not be described in detail here. A fixing protrusion 81 and a fixing groove 82 are fixed on the end faces of the elastic fixing rod 8 away from each other. A second inclined surface 811 is provided on the outer edge of the side of the fixing protrusion 81 away from the elastic fixing rod 8. When the connecting rod 3 is in a vertical downward position (i.e., during later maintenance), the two elastic fixing rods 8 can rotate to a coaxial abutting state. At this time, the fixing protrusion 81 on one of the two elastic fixing rods 8 is inserted into the fixing groove 82 on the other elastic fixing rod 8, so as to better support and limit the flexible collection bag 5.

[0035] Reference Figure 8 The left and right sides of the fixed plug 13 are provided with first slots 132; when the moving wheel 62 is facing down (that is, moving a short distance), the two elastic fixing rods 8 can rotate to the coaxial state. Using the elastic force of the elastic fixing rods 8, the fixing protrusion 81 is inserted into the corresponding first slot 132 at this time, thereby enhancing the installation stability of the box 1 and the supporting rod 4.

[0036] Reference Figure 9 and Figure 10 When the connecting rod 3 is rotated to a horizontal state and the receiving rod 4 is rotated to a vertical downward state, the traction handle 7 can be rotated to a tilted backward state. At this time, a second slot 72 is provided on the outer side of the traction handle 7 facing forward. When the metering box is in normal use, first turn the traction handle 7 to the tilted rear position, turn the connecting rod 3 to the horizontal position and the receiving rod 4 to the vertical downward position, and then turn the two elastic fixing rods 8 to the parallel side by side. At this time, the fixing protrusion 81 can be inserted into the second slot 72 to further fix the traction handle 7. The traction handle 7 is used to provide tilt support for the box body 1, thereby enhancing the installation stability of the box body 1.

[0037] The implementation principle of this application embodiment is as follows: When moving short distances, both the connecting rod 3 and the supporting rod 4 rotate to a horizontal position that abuts against the bottom surface of the box 1, the moving wheel 62 faces downwards, the two elastic fixing rods 8 are coaxial, and the fixing protrusion 81 is inserted into the first slot 132 of the fixing block 13 to enhance stability. The staff can move the box 1 with the help of the moving wheel 62 by pulling the handle 7.

[0038] During normal use, the connecting rod 3 is rotated to the horizontal position, the receiving rod 4 is rotated to the vertical downward position, the traction handle 7 is rotated to the tilted rear position, the two elastic fixing rods 8 are rotated to the parallel side-by-side position, the fixing protrusion 81 is inserted into the second slot 72 of the traction handle 7 to fix the state of each component, and the traction handle 7 provides tilt support to the box 1 to improve installation stability.

[0039] During maintenance, the connecting rod 3 is vertically downward and the receiving rod 4 is horizontally forward. The limiting rod 41 is used to initially limit and fix this state. The traction handle 7 is turned vertically upward, and the fixing block 13 is inserted into the fixing slot 71 by its own elasticity to further lock the component. The two elastic fixing rods 8 are coaxially abutted, and the fixing protrusion 81 is inserted into the corresponding fixing groove 82 to support and limit the flexible collection bag 5. The opening of the flexible collection bag 5 is elastically clamped and fixed by the fastening rod 61 and the receiving rod 4, which can temporarily store waste parts.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
