Technical Field
[0001] This utility model relates to the technical field of electricity metering boxes, specifically to an anti-theft electricity metering box. Background Technology
[0002] Electricity metering boxes are enclosures used to install electricity metering devices and related equipment. They provide a safe and stable environment for electricity metering, ensuring the accuracy and reliability of electricity metering. They play a vital role in the power system and are widely used in various electricity-consuming locations such as residential buildings, commercial buildings, and industrial plants. In order to prevent illegal electricity theft, tampering with meter data, or damage to power facilities, electricity metering boxes need to be protected against theft.
[0003] Currently, electricity meter boxes are protected against theft using combination locks and fingerprint locks, or by using tamper-evident locks. Equipped with professional-grade tamper-evident locks, these boxes increase the difficulty of unauthorized opening. The tamper-evident locks lock the box body and door, thus achieving theft prevention. However, since the tamper-evident locks are exposed, it is only a matter of time before criminals find their location and pry them open. Current electricity meter boxes do not use concealed locks, and improvements should be made to address this issue.
[0004] Therefore, an anti-theft electricity metering box is proposed. Utility Model Content

[0024] like Figures 1 to 4 As shown, an anti-theft electricity metering box includes a base 1, a box body 2, and a box door 3. A stop bar 4 is fixedly provided on the surface of the box body 2. A telescopic mechanism 5 for opening and closing the box door 3 is provided on the surface of the box body 2, and the box door 3 is slidably installed on the surface of the telescopic mechanism 5. Figure 2 , Figure 3 As shown, specifically, the telescopic mechanism 5 includes a cavity 501, the surface of the box 2 is provided with a cavity 501, a movable plate 502 is slidably installed inside the cavity 501, a groove 503 is provided on one side surface of the movable plate 502, a guide rail 504 is fixedly provided on the surface of the movable plate 502, and the box door 3 is slidably installed with the guide rail 504.
[0025] More specifically, the sliding of the movable plate 502 causes the guide rail 504 and the box door 3 to move. When the movable plate 502 slides into the cavity 501, the box door 3 is in contact with the box body 2. At this time, the stop bar 4 can block one side of the box door 3, thereby restricting the sliding of the box door 3. When the movable plate 502 slides out, the guide rail 504 and the box door 3 move away from the box body 2 and the stop bar 4. At this time, the box door 3 can be slid to one side, and the surface of the movable plate 502 can be temporarily placed with maintenance tools.
[0026] The surfaces of the housing 2 and the base 1 are provided with locking mechanisms 6 for locking the telescopic mechanism 5, such as... Figures 2 to 4 As shown, specifically, the locking mechanism 6 includes a locking plate 601, which is slidably provided on the top of the housing 2. An embedded block 602 is fixedly provided on the surface of the locking plate 601, and the embedded block 602 is adapted to the groove 503. The locking plate 601 is L-shaped. A door lock 603 is provided on the back of the housing 2. A keyhole is provided on the surface of the locking plate 601, and the keyhole is adapted to the door lock 603. A hidden groove 604 is provided on the surface of the base 1, and the hidden groove 604 is adapted to the door lock 603.
[0027] More specifically, by sliding the locking plate 601, the locking plate 601 is moved. When the movable plate 502 slides into the cavity 501, the sliding locking plate 601 makes its surface fit against the surface of the housing 2, thereby causing the embedded block 602 to be embedded into the groove 503, thus locking the movable plate 502. The locking plate 601 and the housing 2 can be locked by the door lock 603 and the keyhole, thereby restricting the sliding of the locking plate 601. When the door lock 603 is located inside the hidden groove 604, the door lock 603 is hidden.
[0028] The surfaces of the base 1 and the housing 2 are provided with a moving mechanism 7 for driving the housing 2 to move horizontally, such as... Figure 1 , Figure 4 As shown, specifically, the moving mechanism 7 includes a slide groove 701. The slide groove 701 is formed on the surface of the base 1. A threaded rod 702 is rotatably provided on the inner wall of the slide groove 701. A slider 703 is threadedly connected to the surface of the threaded rod 702. The slider 703 is slidably installed with the slide groove 701. The top of the slider 703 is fixedly connected to the bottom of the housing 2. One end of the threaded rod 702 passes through the surface of the base 1 and extends to the outside of the slide groove 701. A polygonal groove is formed at this end of the threaded rod 702.
[0029] More specifically, when the threaded rod 702 rotates, the slider 703 slides, the groove 701 can limit the slider 703, the slider 703 can slide inside the groove 701, the polygonal groove at one end of the threaded rod 702 needs to be inserted with a specific wrench, the threaded rod 702 is rotated by the wrench, thereby causing the box 2 to move horizontally.
[0030] In summary: When the box door 3 needs to be opened, the moving mechanism 7 is first used with a specific wrench to drive the box body 2 to move, thereby revealing the hidden lock on the locking mechanism 6. At this time, the locking mechanism 6 releases the lock on the telescopic mechanism 5. After the lock on the telescopic mechanism 5 is released, the telescopic mechanism 5 moves the box door 3 away from the box body 2, thereby releasing the sliding limit of the stop bar 4 on the box door 3. At this time, the box door 3 can slide to one side, thereby opening the box door 3. After the telescopic mechanism 5 is extended, the surface of the telescopic mechanism 5 can be used to temporarily store maintenance tools, thus providing convenience for relevant personnel. This electricity metering box adopts a hidden lock design, hiding the lock inside the base 1. It is difficult to directly find the lock position from the outside, increasing the difficulty of breaking the lock to open the base 1. It can effectively prevent criminals from opening the metering box by force or prying the lock, improving the anti-theft performance. In addition, it adopts a multi-layer protection structure, thereby increasing the difficulty of opening the metering box.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
