Description

Technical Field

[0001] This application relates to the field of electricity metering boxes, and more particularly to a modular electricity metering box. Background Technology

[0002] Electricity metering boxes are essential devices before power lines enter households. With economic development, accelerated urbanization, and industrial upgrading, especially the widespread use of household appliances, the proportion of electricity consumption in the tertiary sector and by residents continues to increase, leading to a continuous increase in electricity demand. The country is increasing its investment in power infrastructure, including rural power grid renovation and urban reconstruction. Therefore, electricity metering boxes, as terminal metering devices for electricity products, have broad development prospects.

[0003] Electricity meter boxes are usually installed on the walls of buildings. When inspecting electricity meter boxes, maintenance tools are required. However, personnel working at heights need to carry the maintenance tools in bags on their backs, which not only increases the burden on maintenance personnel but also makes it inconvenient to access the maintenance tools. Summary of the Invention

[0004] To improve ease of maintenance, this application provides a modular power metering box.

[0005] This application provides a modular energy metering box, which adopts the following technical solution: A modular electricity metering box includes a box body, on which a shelf is movably disposed. The shelf has a placement slot. The shelf can be moved to a position below the box body with the opening of the placement slot facing upwards. The shelf can also be moved to a position above the box body and placed on the top wall of the box body.

[0006] By adopting the above technical solution, the shelf is designed to be movable to the bottom or top of the box, allowing operators to flexibly adjust its position according to actual needs. When maintenance personnel are repairing the electricity metering box, rotating the shelf to the bottom of the box with the slot opening facing upwards provides a stable and convenient temporary working platform for tools. When the electricity metering box is working normally, rotating the shelf to the top of the box and placing it on the top wall protects the top wall, reducing damage from falling objects and improving the functionality of the shelf.

[0007] Optionally, a vertically extending groove is formed on the outer surface of the box body, a movable rod is fixedly connected to the end of the shelf, and a rotating block is fixedly connected to the end of the movable rod away from the shelf. The rotating block can slide in the groove and can also rotate in the groove. The rotation axis of the rotating block extends along the width direction of the box body.

[0008] By adopting the above technical solution, a vertically extending slide groove is set up to cooperate with a movable rod with a rotating block. When the electricity metering box is working normally, the shelf is placed on the top wall of the box and can achieve self-locking. When the electricity metering box needs to be repaired, the shelf is first raised so that the rotating block slides upward along the slide groove. Then the movable rod is rotated so that the rotating block rotates in the slide groove, thereby driving the shelf to rotate to the bottom of the box. Then the shelf is lowered so that the rotating block slides along the slide groove to the bottom of the slide groove. When the hand is released, the shelf can remain in the state of being below the box under the action of gravity. Even if there is a slight shaking of the shelf, it will not affect the use. This application enables the shelf to slide smoothly along the height of the box and adjust its posture at appropriate positions by rotating the rotating block around the width axis. This combination of sliding and rotating connection not only allows for flexible switching and reliable fixing of the shelf in the upper and lower positions of the box, but also makes the shelf move more smoothly and stably, improving the overall ease of operation and mechanical reliability of the structure. Furthermore, the structure is simple, easy to process, and reduces processing costs.

[0009] Optionally, the slide groove is formed on the opposite side walls of the box body along the width direction, the slide groove penetrates the top wall of the box body, and two movable rods are provided, which are respectively fixedly connected to the two ends of the shelf along the width direction of the box body.

[0010] By adopting the above technical solution, sliding grooves penetrating the top wall are opened on opposite side walls in the width direction of the cabinet, and two movable rods are respectively set to connect the two ends of the shelf, realizing synchronous guidance and support on both sides during the lifting and lowering process of the shelf. This symmetrical layout effectively enhances the balance and stability of the shelf during movement, preventing jamming or tilting caused by uneven force on one side. At the same time, the sliding groove design penetrating the top wall facilitates the insertion of the rotating block into the groove, simplifying the installation steps and enabling the shelf to be detached.

[0011] Optionally, a folding plate is rotatably provided on the shelf, the rotation axis of the folding plate extends along the width direction of the box, and the folding plate can be rotated to be parallel to the shelf.

[0012] By adopting the above technical solution, a foldable panel is rotatably installed on the shelf, further expanding the shelf's functionality. When the shelf is located above the box, the foldable panel can rotate to be parallel to the shelf, thus providing a rainproof effect and improving the rain protection of the electricity metering box.

[0013] Optionally, there is a distance between the shelf and the front wall of the box, and when the folding plate is rotated to be parallel to the shelf, the folding plate abuts against the top wall of the box.

[0014] By adopting the above technical solution, when the shelf is above the cabinet, the folding panel can contact the top wall of the cabinet when rotated to be parallel to the shelf. This allows the folding panel to receive top support from the cabinet in the unfolded state, keeping it in a horizontal position. This contact structure effectively prevents the folding panel from accidentally flipping or vibrating due to external forces, while eliminating the need for complex locking mechanisms, simplifying the structure and improving safety during use.

[0015] Optionally, a fixing structure is also included, wherein a door is rotatably provided on the front wall of the box, and when the storage panel is located below the box, the folding panel can keep the door in the open state through the fixing structure.

[0016] By adopting the above technical solution and setting a fixed structure, the folding plate can keep the cabinet door open when the storage plate is below the cabinet body, preventing the cabinet door from accidentally closing due to wind or vibration during maintenance and affecting operation. This design organically combines the fixing functions of the folding plate and the cabinet door, achieving temporary fixation of the cabinet door without additional operation or tools, further improving the continuity and efficiency of the maintenance process, and demonstrating the multi-functional integrated characteristics of the structure.

[0017] Optionally, the fixing structure includes a transmission rod, a connecting rod, and an abutment rod. A through hole is vertically provided on the bottom wall of the box for the transmission rod to pass through and slide. The two ends of the connecting rod are rotatably connected to the transmission rod and the abutment rod, respectively. The abutment rod slides on the inner wall of the box along the thickness direction of the box. When the shelf is located below the box, the folding plate can be rotated to be placed vertically and abut against the end of the transmission rod away from the connecting rod. The end of the abutment rod away from the connecting rod can extend out of the inner cavity of the box and abut against the box door.

[0018] By adopting the above technical solution, a linkage-type fixing structure composed of a transmission rod, a connecting rod, and an abutment rod is used to realize the mechanical transmission and control of the folding plate's door holding mechanism. When the transmission rod is raised, it can drive the connecting rod to swing, ultimately causing the end of the abutment rod to extend out of the inner cavity of the box. The abutment rod can abut against the box door, so that the box door opens 90° without closing (it can also be greater than 90°, in short, with the abutment rod abutting, the box door will not close). When the folding plate rotates to the vertical position and abuts against the transmission rod, it can limit and lock the transmission rod. This structure uses a simple rod system transmission to realize automatic linkage from the movement of the folding plate to the fixing of the box door. It is intuitive to operate, mechanically reliable, and requires no electricity or complex control. It also keeps the abutment rod in the state where its end extends out of the inner cavity of the box, making it suitable for various field environments.

[0019] Optionally, a locking block is provided at the end of the transmission rod away from the connecting rod, and a slot for inserting the locking block is provided on the folding plate.

[0020] By adopting the above technical solution, a locking block is set at the end of the transmission rod to cooperate with the locking groove on the folding plate, so that the folding plate can form a stable locking relationship with the transmission rod when in the vertical position. This locking structure not only enhances the connection between the folding plate and the transmission rod and prevents accidental disengagement, but also provides a clear action holding position for the transmission rod, ensuring that the fixing structure can accurately and reliably perform the door locking function and maintain it after the folding plate is in place, thereby improving the accuracy and stability of the entire linkage process.

[0021] Optionally, a resetting elastic element is connected between the abutment rod and the housing to retract the end of the abutment rod into the inner cavity of the housing.

[0022] By adopting the above technical solution, a reset elastic element is installed between the abutment rod and the housing, so that after the folding plate is retracted and the abutment against the transmission rod is released, the abutment rod can automatically retract into the housing cavity under the action of elasticity. This automatic reset mechanism ensures the timely release of the fixed state of the housing door, allowing the housing door to close normally, while avoiding interference or damage that may be caused by the long-term exposure of the abutment rod, thus improving the durability of the structure and the ease of restoration after use.

[0023] Optionally, the folding plate is provided with multiple casters.

[0024] By adopting the above technical solution, multiple casters are installed on the folding panel, allowing the entire electricity metering box to be moved flexibly using the casters when the shelf is located below the box and the folding panel is folded. This design greatly enhances the portability and adaptability of the modular electricity metering box, making it easier for installers to move the electricity metering box to a suitable location before installing it on the wall.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The storage board is designed to be movable to the bottom or top of the box, allowing operators to flexibly adjust its position according to actual needs, thus improving its functionality. 2. The shelf can slide smoothly along the height of the box, and its posture can be adjusted at appropriate positions by rotating the rotating block around the width axis. This not only enables flexible switching and reliable fixing of the shelf in the upper and lower positions of the box, but also makes the shelf move more smoothly and stably, improving the ease of operation and mechanical reliability of the entire structure. In addition, the structure is simple, easy to process, and reduces processing costs. 3. By using a simple linkage transmission, automatic linkage from the movement of the folding plate to the fixing of the box door is realized. The operation is intuitive and mechanically reliable. It does not require electricity or complex control and keeps the abutment rod in the state of extending out of the box cavity at the end. It is suitable for various field environments.

Detailed Implementation

[0032] The following combination Figures 1-5 This application will be described in further detail.

[0033] This application discloses a modular power metering box. (Refer to...) Figure 1 and Figure 2 The modular energy metering box includes a box body 1 and a shelf 2. The shelf 2 has a slot 21 for placing maintenance tools. The shelf 2 is movably mounted on the box body 1. This movable connection allows the shelf 2 to be positioned either below the box body 1 with the opening of the slot 21 facing upwards, or above the box body 1 and placed on the top wall of the box body 1. This flexible adjustment of the shelf 2's position facilitates maintenance operations and protects the box body 1.

[0034] Reference Figure 1 The enclosure 1 is typically made of engineering plastics (such as PC or ABS, which are corrosion-resistant and have good insulation) or galvanized steel sheet (high strength, used for outdoor or large enclosures). Multiple ventilation holes (actually louvered holes, represented as through holes in the diagram) are provided on both side walls of enclosure 1. Functional modules (not shown in the diagram) are installed inside the enclosure 1. These modules include a metering module, an incoming line switch module, an outgoing line protection module, and auxiliary function modules. Each module uses standardized modular components (such as rail-mounted modular electrical appliances) and a unified electrical interface, thus achieving a modular design for the electricity metering box.

[0035] Reference Figure 1 and Figure 2Two doors 7 are rotatably installed on the front wall of the box 1. The rotation axis of the doors 7 extends along the height direction of the box 1, and the two doors 7 are symmetrically arranged. The doors 7 can be opened to expose the inner cavity of the box 1, and the doors 7 can also be closed to completely seal the box 1.

[0036] Reference Figure 2 The storage slots 21 on the shelf 2 can be rectangular, circular, or other shapes, and their function is to provide storage space for tools and other items. For example, the storage slots 21 can be designed as compartments of different sizes for classifying and storing different tools. The shelf 2 can be made of high-strength plastic or metal to ensure sufficient strength and durability.

[0037] Reference Figure 3 and Figure 3 Movable rods 3 are fixedly connected to both ends of the shelf 2, which is arranged along the width direction of the box body 1. The movable rods 3 can be fixed to the shelf 2 by welding or bolting. The movable rods 3 extend along the thickness direction of the shelf 2. Rotating blocks 4 are fixedly connected to the opposite surfaces of the two movable rods 3, and the rotating blocks 4 are located at the ends of the movable rods 3 away from the shelf 2. The rotating blocks 4 can also be connected to the movable rods 3 by welding or integral molding. The rotating blocks 4 are cylindrical, and their surfaces can be polished. The material of the rotating blocks 4 can be a wear-resistant metal material, such as stainless steel.

[0038] Reference Figure 2 and Figure 3 The outer surfaces of the two opposite sidewalls of the housing 1, arranged along the width direction, are each provided with a vertically extending groove 11. The groove 11 penetrates the top wall of the housing 1. The groove 11 can be machined to ensure a smooth surface. Two different rotating blocks 4 are inserted into the two grooves 11 respectively. The rotating blocks 4 can slide and rotate within the grooves 11, and their rotation axis extends along the width direction of the housing 1. The depth and width of the insertion into the grooves 11 should be rationally designed according to the dimensions of the rotating blocks 4 to ensure smooth sliding and rotation within the grooves 11.

[0039] In other embodiments, only one slide 11 may be provided, and only one movable rod 3 may be provided. In other embodiments, the slide 11 may not penetrate the top wall of the housing 1. In other embodiments, the slide 11 may not be provided, and the rotating block 4 may be detachably installed on the housing 1, allowing the rotating block 4 to be detached from the housing 1 to change the state of the shelf 2.

[0040] Reference Figure 3A folding plate 5 is rotatably mounted on the shelf 2, and the rotation axis of the folding plate 5 extends along the width direction of the box body 1. The rotatable connection between the folding plate 5 and the shelf 2 can be achieved through a rotating component located between the folding plate 5 and the shelf 2. Both ends of the rotating component are rotatably connected to the folding plate 5 and the shelf 2 respectively, ensuring that the folding plate 5 can rotate flexibly, allowing it to rotate 360° relative to the shelf 2. The material of the folding plate 5 can be the same as that of the shelf 2 to ensure overall harmony and durability.

[0041] Reference Figure 1 When the shelf 2 is above the box 1, there is a distance between the shelf 2 and the front wall of the box 1. When the folding plate 5 rotates to be parallel to the shelf 2, the folding plate 5 abuts against the top wall of the box 1. This abutment between the folding plate 5 and the top wall of the box 1 allows the folding plate 5 to be supported by the top of the box 1 in the unfolded state, thus maintaining a horizontal position. This eliminates the need for a complex locking mechanism, simplifying the structure and improving safety during use. In other embodiments, a locking structure can be provided on the folding plate 5 and the shelf 2 to keep the folding plate 5 in a horizontal position.

[0042] Reference Figure 2 and Figure 4 The housing 1 is also equipped with a fixing structure 6, which includes a transmission rod 61, a connecting rod 62, and an abutment rod 63. The transmission rod 61 extends vertically, and a through hole 12 is provided vertically on the bottom wall of the housing 1 for the transmission rod 61 to pass through and slide. The size of the through hole 12 is designed according to the diameter of the transmission rod 61 to ensure that the transmission rod 61 can slide smoothly within the through hole 12. The two ends of the connecting rod 62 are rotatably connected to the transmission rod 61 and the abutment rod 63, respectively. This rotatable connection can be achieved by a pin to ensure that the connecting rod 62 can rotate flexibly. The abutment rod 63 is slidably installed on the inner wall of the housing 1 along the thickness direction. A U-shaped plate is fixedly connected to the inner wall of the housing 1 by welding or bolting. The abutment rod 63 slides within the hole of the U-shaped plate to ensure that the abutment rod 63 can slide smoothly.

[0043] Reference Figure 2 and Figure 4 When the transmission rod 61 is raised, it can drive the abutment rod 63 to slide outward of the box body 1 through the connecting rod 62, so that the end of the abutment rod 63 extends out of the inner cavity of the box body 1. If the box door 7 is rotated to close, the end of the abutment rod 63 can abut the box door 7, so that the box door 7 can rotate up to 90° with the front wall of the box body 1, preventing the box door 7 from closing.

[0044] Reference Figure 2 and Figure 4When the storage plate 2 is located below the box body 1, the folding plate 5 can be rotated to be placed vertically and abut against the end of the transmission rod 61 away from the connecting rod 62, thereby locking the transmission rod 61 and keeping the abutting rod 63 in a state where its end extends out of the inner cavity of the box body 1.

[0045] Reference Figure 3 and Figure 4 A locking block 8 is integrally formed on the end of the transmission rod 61 away from the connecting rod 62, and a slot 51 for inserting the locking block 8 is provided on the folding plate 5. The shapes of the locking block 8 and the slot 51 can be designed as rectangular or circular, etc. After the locking block 8 is inserted into the slot 51, it enhances the connection between the folding plate 5 and the transmission rod 61, prevents accidental disengagement, provides a clear action holding position for the transmission rod 61, and ensures that the fixing structure 6 can accurately and reliably perform the locking function of the door 7 and maintain it after the folding plate 5 is in place, thereby improving the accuracy and stability of the entire linkage process.

[0046] Reference Figure 2 and Figure 4 A resetting elastic element 9 is connected between the abutment rod 63 and the U-shaped plate installed on the housing 1 that guides the abutment rod 63, causing the end of the abutment rod 63 to retract into the inner cavity of the housing 1. The resetting elastic element 9 can be a spring, and the spring constant should be reasonably selected according to actual needs. A protrusion is integrally formed on the outer surface of the abutment rod 63. The resetting elastic element 9 is a compression spring, with one end of the compression spring abutting against the protrusion on the abutment rod 63 and the other end abutting against the U-shaped plate.

[0047] Reference Figure 5 Multiple casters 100 are installed on the folding plate 5. The casters 100 can be fixed to the folding plate 5 by bolts or welding. The number and distribution of the casters 100 should be reasonably designed according to the size and weight of the folding plate 5 to ensure that the entire electricity metering box can be moved flexibly by the casters 100. When the shelf 2 is located under the box body 1 and the folding plate 5 is folded, the entire electricity metering box can be moved flexibly by the casters 100, which greatly enhances the portability and adaptability of the modular electricity metering box, making it easier for installers to move the electricity metering box to a suitable position before installing it on the wall.

[0048] The assembly principle of a modular electricity metering box according to an embodiment of this application is as follows: When the electricity metering box is working normally, the shelf 2 is placed on the top wall of the box body 1, which can achieve self-locking and protect the top wall of the box body 1. The folding plate 5 can be rotated to be parallel to the shelf 2, thereby providing a rainproof effect. When the electricity metering box needs to be repaired, the box door 7 is opened, the shelf 2 is first raised, so that the rotating block 4 slides upward along the slide groove 11, and then the movable rod 3 is rotated, so that the rotating block 4 rotates in the slide groove 11, thereby driving the shelf 2 to rotate below the box body 1. At the same time, the folding plate 5 is rotated 90°, so that the folding plate 5 is above the shelf 2. At the same time, the transmission rod 61 is raised, so that the end of the abutment rod 63 extends out of the inner cavity of the box body 1. At this time, the locking block 8 is inserted into the locking slot 51 to lock the transmission rod 61 and the folding plate 5. When the storage plate 2 is located below the housing 1, the rotating block 4 is located at the bottom of the slide 11. The storage plate 2 can be kept below the housing 1 under the action of gravity, providing maintenance personnel with a stable and convenient temporary working platform for picking up and putting down tools.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
