Description
Technical Field
[0001] This utility model relates to the field of power metering technology, specifically to an anti-tampering intelligent metering box. Background Technology
[0002] As the carrier and protection device for electricity meters, the security and tamper-proof performance of the metering box directly affect the accuracy and fairness of electricity metering.
[0003] Traditional metering boxes have two major problems: First, the locking structure of most metering boxes is simple and easily pried open or opened illegally, leading to tampering with the internal electricity meter, damage to wiring, and distortion of metering data, causing economic losses to the power supplier or users. Second, in order to read data such as electricity consumption and operating status of the electricity meter, staff need to frequently open the metering box cover, which not only increases the complexity of operation, but also damages the original sealing structure due to repeated opening, further reducing the anti-tampering capability. At the same time, frequent operation may also cause accidental damage to the internal components of the box. In view of this, we propose an anti-tampering smart metering box to solve the existing problems. Utility Model Content
[0004] The purpose of this invention is to provide a tamper-proof intelligent metering box to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tamper-proof smart metering box, comprising a metering box, an electricity meter, a cover plate, an observation window, a limiting mechanism, a mounting groove, and mounting components. The metering box has an mounting groove inside, and mounting components are symmetrically arranged in the mounting groove. The electricity meter is detachably mounted on the mounting groove through the mounting components. A cover plate is movably connected to one side of the metering box. The cover plate and the groove opening cooperate with each other, and a gear-driven limiting mechanism is provided in the mounting groove.
[0006] Preferably, the limiting mechanism includes a rotating rod, a first bevel gear, a second bevel gear, a movable rod, a first synchronous pulley, a synchronous belt, a limiting chamber, a rotating disk, a driving component, a second synchronous pulley, a driving groove, a top rod, a limiting groove, a limiting block, a return spring, a limiting component, and a driving chamber. The limiting chamber is fixedly connected in the mounting groove. A driving groove is opened in the inner chamber. The second synchronous pulley is movably connected in the driving groove. A rotating disk is fixedly connected to the second synchronous pulley. Driving components are respectively arranged on both sides of the rotating disk. A limiting block is movably connected to one side of each driving component. A top rod is fixedly connected to one side of each limiting block.
[0007] Preferably, the limiting chamber has limiting grooves on both sides, one end of the top rod is located in the limiting groove, and a limiting component is fixedly connected to the top rod. A reset spring is sleeved on the top rod between the limiting component and the limiting groove.
[0008] Preferably, the mounting slot is fixedly connected to a drive chamber on one side of the limiting chamber, a movable rod is movably connected inside the drive chamber, a first synchronous pulley is fixedly connected to the movable rod, a synchronous belt is sleeved on the first synchronous pulley and the second synchronous pulley, and a second bevel gear is fixedly connected to the movable rod.
[0009] Preferably, the cover plate is provided with a rotating rod, and a first bevel gear is fixedly connected to the rotating rod, with the first bevel gear and the second bevel gear meshing with each other.
[0010] Preferably, an observation window is provided on one side of the cover plate, and the observation window cooperates with the electricity meter.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. When the cover plate closes downwards, the rotating rod on the cover plate rotates synchronously with the cover plate, driving the first bevel gear fixed on the rotating rod to rotate. The first bevel gear meshes with the second bevel gear in the drive chamber, driving the movable rod coaxial with it to rotate. The first synchronous wheel on the movable rod rotates with the movable rod, and through the sleeved synchronous belt, the power is transmitted to the second synchronous wheel in the limiting chamber, driving the rotating disk fixedly connected to it to rotate synchronously. The driving components on both sides of the rotating disk push the limiting blocks on both sides, forcing the limiting blocks to move outwards. The limiting blocks drive the top rod to extend outwards along the limiting groove. The end of the top rod abuts against the corresponding locking position of the cover plate, forming a mechanical limit, so that the cover plate cannot be illegally opened.
[0013] 2. The location, size, and shape of the observation window on the cover plate are precisely aligned with the electricity meter in the installation slot, allowing direct reading of data such as electricity consumption and operating status from the electricity meter. This avoids the risk of tampering caused by opening the cover plate. The presence of the observation window ensures that the cover plate remains in a closed state locked by the limit mechanism for an extended period. Attached Figure Description

[0020] like Figures 1-4 As shown, the present invention proposes an anti-tampering smart metering box, comprising a metering box 1, an electricity meter 2, a cover plate 3, an observation window 4, a limiting mechanism 5, a mounting groove 6, and mounting components 7. The metering box 1 has an mounting groove 6 inside, and mounting components 7 are symmetrically arranged in the mounting groove 6. The electricity meter 2 is detachably connected to the mounting groove 6 through the mounting components 7. The cover plate 3 is movably connected to one side of the metering box 1. The cover plate 3 and the groove of the mounting groove 6 cooperate with each other, and the mounting groove 6 is provided with a gear-driven limiting mechanism 5.
[0021] In an optional embodiment, the limiting mechanism 5 includes a rotating rod 501, a first bevel gear 502, a second bevel gear 503, a movable rod 504, a first synchronous pulley 505, a synchronous belt 506, a limiting chamber 507, a rotating disk 508, a driving component 509, a second synchronous pulley 510, a driving groove 511, a top rod 512, a limiting groove 513, a limiting block 514, a return spring 515, a limiting component 516, and a driving chamber 517. The limiting chamber 507 is fixedly connected in the mounting groove 6. A driving groove 511 is opened in the inner chamber. The second synchronous pulley 510 is movably connected in the driving groove 511. The rotating disk 508 is fixedly connected to the second synchronous pulley 510. Driving components 509 are respectively arranged on both sides of the rotating disk 508. A limiting block 514 is movably connected to one side of each driving component 509. A top rod 512 is fixedly connected to one side of the limiting block 514.
[0022] In an optional embodiment, the limiting chamber 507 has limiting grooves 513 on both sides, one end of the push rod 512 is located in the limiting groove 513, and a limiting member 516 is fixedly connected to the push rod 512. A return spring 515 is sleeved on the push rod 512 between the limiting member 516 and the limiting groove 513.
[0023] In an optional embodiment, the mounting groove 6 is fixedly connected to a drive chamber 517 on one side of the limiting chamber 507. A movable rod 504 is movably connected inside the drive chamber 517. A first synchronous pulley 505 is fixedly connected to the movable rod 504. A synchronous belt 506 is sleeved on the first synchronous pulley 505 and the second synchronous pulley 510. A second bevel gear 503 is fixedly connected to the movable rod 504.
[0024] In an optional embodiment, a rotating rod 501 is provided on the cover plate 3, and a first bevel gear 502 is fixedly connected to the rotating rod 501. The first bevel gear 502 and the second bevel gear 503 mesh with each other.
[0025] When the cover plate 3 is closed downwards, the rotating rod 501 on the cover plate rotates synchronously with the cover plate 3, driving the first bevel gear 502 fixed on the rotating rod 501 to rotate. The first bevel gear 502 meshes with the second bevel gear 503 in the drive chamber 517, driving the movable rod 504 coaxial with it to rotate.

[0027] The position, size, and shape of the observation window 4 on the cover plate 3 are precisely aligned with the electricity meter 2 in the mounting slot 6, allowing direct reading of data such as electricity consumption and operating status of the electricity meter 2. This avoids the risk of tampering caused by opening the cover plate. The presence of the observation window ensures that the cover plate 3 can remain in a closed state locked by the limiting mechanism 5 for an extended period of time.
[0028] The working principle of this utility model is as follows: When the cover plate 3 is closed downwards, the rotating rod 501 on the cover plate rotates synchronously with the cover plate 3, driving the first bevel gear 502 fixed on the rotating rod 501 to rotate. The first bevel gear 502 meshes with the second bevel gear 503 in the drive chamber 517, driving the movable rod 504 coaxial with it to rotate.

The limiting blocks 514 drive the top rod 512 to extend outwards along the limiting groove 513. The end of the top rod 512 abuts against the corresponding locking position of the cover plate 3, forming a mechanical limit, so that the cover plate cannot be illegally opened.
