[0001] This utility model relates to the technical field of electricity metering box equipment, and more specifically to a multi-position electricity metering box in which the incoming line room and the metering room share a single lock. Background Technology

[0002] An electricity metering box is a core device for electricity metering. It contains electricity meters that measure electricity. Multi-meter metering boxes are widely used in multi-user centralized power supply scenarios because they can accommodate multiple meters at the same time.

[0003] The existing multi-position meter box with publication number CN214669238U has advantages such as convenient and simple operation and maintenance, and the ability to operate the outgoing line switch, insert the meter card, and read the meter without opening the box door. However, this utility model also has the following problems: due to the different operating needs of the owner and the staff, when the staff performs maintenance on the meter box, they need to operate the incoming line compartment and the metering compartment at the same time. However, the incoming line compartment and the metering compartment of the existing meter box need to be opened by different door locks, which makes the staff have to repeatedly open and close different box doors, which is cumbersome and seriously affects the maintenance efficiency. Therefore, this utility model proposes a multi-position energy metering box in which the incoming line compartment and the metering compartment share a single lock. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-meter energy metering box that shares a single lock between the incoming line room and the metering room. This single lock can further optimize the spatial zoning, ease of operation, and structural safety in multi-meter scenarios.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multi-position energy metering box that shares a single lock for the incoming line compartment and the metering compartment includes a box body. An upright plate is fixedly installed on the inner side of the box body, which divides the box body into an incoming line compartment and a metering compartment. A main door is hinged to one side of the box body via a hinge. A secondary door is hinged to the main door at the position corresponding to the incoming line compartment via a hinge, and a secondary door is hinged to the main door at the position corresponding to the metering compartment via a hinge. The main door is fixed to the box body by a mechanical lock.

[0006] Furthermore, side columns are fixedly installed inside the main body of the box on both sides of the inlet chamber and both sides of the metering chamber.

[0007] Furthermore, a panel one is fixedly provided on the upper end of the side column of the inlet chamber, and a panel two is provided on the upper end of the side column of the metering chamber. A partition plate is vertically fixed at the center of the upper surface of the panel two.

[0008] Furthermore, each of the panel one, panel two, partition plate and upright plate is provided with a number of wire holes.

[0009] Furthermore, the metering chamber is divided into several meter compartments by panel two and partitions.

[0010] Furthermore, each of the secondary doors is equipped with a viewing window corresponding to the position of each meter room, and the lower end of each viewing window is hinged to the inner door.

[0011] Furthermore, the inner door and the second secondary door, the first secondary door and the main door, and the second secondary door and the main door are all fixed by mechanical locks.

[0012] Furthermore, the inner door, secondary door one, secondary door two, and main door are all equipped with L-shaped recessed handles.

[0013] Beneficial effects: This utility model separates the incoming line room and the metering room by using a vertical plate, and with the main door linked to the secondary doors one and two, the incoming line room and the metering room can share a single lock for control. When the staff is performing maintenance, there is no need to open the locks of the two areas separately, which reduces the number of operation steps, avoids the problems of carrying keys and unlocking errors, and significantly shortens the maintenance time.

Detailed Implementation

[0017] like Figures 1 to 2 As shown in this specific embodiment, a multi-position energy metering box sharing a single lock for the incoming line compartment and the metering compartment includes a box body 1. A vertical plate 17 is fixedly installed on the inner side of the box body 1, dividing the box body 1 into an incoming line compartment 9 and a metering compartment 10. A main door 2 is hinged to one side of the box body 1 via a hinge. The main door 2 is fixed to the box body 1 via a mechanical lock 7. The vertical plate 17 separates the incoming line compartment 9 and the metering compartment 10. Combined with the structure of the main door 2 linking with secondary doors 3 and 4, the incoming line compartment 9 and the metering compartment 10 can share a single lock for control. When it is necessary to simultaneously inspect the power supply line of the incoming line compartment 9 and the meter in the metering compartment 10, the operator uses a special key to open the mechanical lock 7 between the main door 2 and the box body 1, and pulls the main door 2 outward to achieve convenient one-lock opening for maintenance. The main door 2 is hinged to the secondary door 3 at the position corresponding to the incoming line compartment 9, and to the secondary door 4 at the position corresponding to the metering compartment 10. If the incoming line compartment 9 needs to be inspected, the secondary door 3 can be opened alone. If the metering compartment 10 needs to be inspected, the secondary door 4 can be opened alone. It is not affected by the shared lock of the main door 2, and it can also effectively prevent the other incoming line compartment 9 or metering compartment 10 from being exposed when only one of them needs to be inspected.

[0018] With the above-mentioned structure in place, when staff are carrying out maintenance, they can open two areas simultaneously with one lock, or open the corresponding area individually for maintenance as needed, effectively reducing operation steps and significantly shortening maintenance time.

[0019] like Figure 2 As shown, side columns 16 are fixedly installed on both sides of the inlet chamber 9 and the metering chamber 10 inside the main body 1 of the box. The side columns 16 can serve as a support carrier for the panel, and the number and position of the panel can be changed and adjusted according to the number of meters required.

[0020] A panel 15 is fixedly installed on the upper end of the side column 16 of the incoming line compartment 9, and a panel 2 12 is installed on the upper end of the side column 16 of the metering compartment 10. A partition plate 13 is vertically fixed at the center of the upper surface of the panel 2 12. The panel 15 and the panel 2 12 can divide the space of the incoming line compartment 9 or the metering box according to the needs, reducing the problem of equipment clutter. The metering compartment 10 is divided into several meter compartments 11 by the panel 2 12 and the partition plate 13, which can clearly distinguish the meter area of ​​individual users and prevent confusion during maintenance.

[0021] Several wire holes 14 are provided on panel 15, panel 2 12, partition plate 13 and upright plate 17. The wire holes 14 not only solve the heat dissipation needs of the equipment in the box and prevent the meter from being damaged by high temperature, but also provide a unified passage for power lines and signal lines, solving potential problems such as unplanned wiring, easy tangling and wear, and improving the convenience of product operation and maintenance and the service life of equipment.

[0022] like Figure 1 As shown, each meter compartment 11 is equipped with a viewing window 5 on the secondary door 2 4. The lower end of each viewing window 5 is hinged to the inner door 6. The viewing window 5 allows observation of the meter status without opening the door. The inner door 6 allows card insertion and meter reading without opening the secondary door 2 4, making daily inspections and basic operations more convenient. It also reduces the risk of the equipment inside the box being exposed to dust and moisture, thus improving the reliability of the equipment.

[0023] The inner door 6 is fixed to the secondary door 4, the secondary door 3 is fixed to the main door 2, and the secondary door 4 is fixed to the main door 2 by mechanical locks 7. Different permissions can be set according to operational needs. Users can only open the inner door 6 corresponding to the electricity meter, while staff can have the permission to open the main door 2, the secondary door 3, the secondary door 4, and the inner door 6. This effectively solves the safety hazards such as the lack of distinction in door lock permissions, users operating other electricity meters, and non-professionals accidentally operating the high-voltage power supply line of the incoming line room 9.

[0024] The inner door 6, secondary door 1 3, secondary door 2 4 and main door 2 are all equipped with L-shaped recessed handles 8. The recessed design avoids the risk of bumping and snagging that traditional protruding handles have. The L-shaped structure is ergonomic and serves as a handle.

[0025] Working principle: This utility model divides the interior of the box into an inlet chamber 9 (responsible for external power supply line access) and a metering chamber 10 (responsible for the installation of multiple electricity meters) through a vertical plate 17 fixed inside the main body 1. This achieves physical isolation between the power supply and metering functions, avoids mutual interference between the power supply line and the electricity meter, and reduces the risk of electricity safety. At the same time, the metering chamber 10 is further divided into several independent meter chambers 11 by a panel 12 supported by a side column 16 and a partition plate 13 on the panel 12. This ensures that each electricity meter has its own dedicated space, so that the failure or maintenance of a single electricity meter does not affect the normal operation of other electricity meters, thus meeting the core requirement of multi-meter metering.

[0026] The main door 2 on one side of the main body 1 of this utility model is connected to the main body 1 via a hinge. Secondary doors 3 and 4 are hinged to the main door 2 at positions corresponding to the incoming line chamber 9 and metering chamber 10, respectively. The main door 2 is fixed to the main body 1 by only one mechanical lock 7. When the mechanical lock 7 is opened, the main door 2 can be opened and closed as a whole, simultaneously exposing the operating areas of the incoming line chamber 9 and metering chamber 10 to the secondary doors 3 and 4. This eliminates the need to unlock the doors of the two areas separately, structurally solving the problem of repeated unlocking required for maintenance personnel. It achieves convenient operation by controlling both chambers with a single lock. Furthermore, the independent mechanical locks 7 between the secondary doors 3 and the main door 2, and between the secondary doors 4 and the main door 2, can individually control the opening and closing of the incoming line chamber 9 or the metering chamber 10 as needed, thus balancing overall convenience with local controllability.

[0027] The secondary door 4 of this utility model has a viewing window 5 corresponding to each meter compartment 11. The window is made of transparent material, allowing direct observation of the meter's operating status, such as readings and indicator lights. Daily inspections can be completed without opening any doors, reducing contact between the equipment inside the box and external dust and moisture. The inner door 6 at the bottom of the viewing window 5 is connected to the secondary door 4 via a hinge and is equipped with an independent mechanical lock 7. Only the inner door 6 needs to be opened to complete high-frequency operations such as meter card insertion and meter reading, without opening the entire secondary door 4. This minimizes interference with the internal environment of the metering compartment 10 and extends the service life of the equipment. In addition, the wire holes 14 on the first panel 15, the second panel 12, the partition plate 13, and the upright plate 17 not only allow for air circulation and heat dissipation inside the box, preventing the meters from being damaged by high temperatures, but also provide a unified passage for power lines and signal lines, avoiding wear or tangling caused by messy wiring and ensuring the accuracy of electricity metering.

[0028] This utility model features mechanical locks 7 that are separately controlled between the inner door 6 and the secondary door 4, the secondary door 3 and the main door 2, the secondary door 4 and the main door 2, and the main door 2 and the main body 1. Different keys can be assigned according to the user's role. The owner only holds the key to their own inner door 6, while staff hold all the keys. Staff can also be differentiated by level, with corresponding keys assigned to different personnel for meter maintenance and incoming line room 9 maintenance, forming a three-level protection system of "inner door 6 - secondary door - main door 2". This clearly defines the operation boundaries, avoids unauthorized personnel from accidentally operating the high-voltage lines in the incoming line room 9, and reduces safety hazards. The L-shaped recessed handles 8 on the inner door 6, secondary door 3, secondary door 4, and main door 2 not only avoid the risk of bumping or snagging from protruding handles, but also conform to ergonomics, ensuring grip stability during operation and improving safety and comfort.

[0029] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
