DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figure 1 , Figure 3 and Figure 6 , the present application provides a technical solution: an anti-theft power meter, comprising a power meter body 1 and an anti-theft shell 2, the outer side of the power meter body 1 is provided with the anti-theft shell 2, one side of the anti-theft shell 2 is connected with the power meter body 1 through connecting bolts, the side of the anti-theft shell 2 away from the power meter body 1 is provided with an anti-theft door 201, the anti-theft shell 2 and the anti-theft door 201 are both used for hiding and protecting the power meter body 1.

[0022] The anti-theft power meter effectively avoids the direct contact of the thief with the power meter body 1 for stealing by setting the anti-theft shell 2 and the anti-theft door 201 on the outer side of the power meter body 1 to hide and protect the power meter body 1.

[0023] In Figures 2-6Inside the anti-theft housing 2, an operation box 202, a camera 203, and a drive motor 3 are installed via locking bolts. The bottom of the drive motor 3 is connected to an adjusting screw 301 via a coupling. The outer side of the adjusting screw 301 is threadedly connected to an adjusting rod 302. One side of the adjusting rod 302 is welded to the top of the anti-theft door 201 to drive the anti-theft door 201 to move.

[0024] This anti-theft electricity meter uses an operation box 202 to control a drive motor 3. The output of the drive motor 3 drives an adjusting screw 301 to rotate via a coupling. Through the threaded action with the adjusting screw 302, the adjusting screw 302 moves vertically, which in turn moves the anti-theft door 201 welded to the adjusting screw 302 downwards to open the operation channel, allowing the user to operate the electricity meter body 1. After the operation is completed, the drive motor 3 is restarted. The output of the drive motor 3 drives the adjusting screw 301 to rotate via a coupling. Through the threaded action with the adjusting screw 302, the adjusting screw 302 moves vertically, which in turn moves the anti-theft door 201 welded to the adjusting screw 302 upwards to close the operation channel. This completely protects the electricity meter body 1 inside the anti-theft casing 2 and the anti-theft door 201, and, in conjunction with a camera 203, monitors the surrounding environment of the electricity meter body 1.

[0025] exist Figure 3 and Figure 4 In the anti-theft outer shell 2, a guide groove 404 and a plug-in groove are provided inside. A plug-in block 4 is welded to the top of the anti-theft door 201. The outer side of the plug-in block 4 is plugged into the plug-in groove inside the anti-theft outer shell 2. A positioning groove 401 is provided inside the plug-in block 401. A positioning block 402 is inserted into the positioning groove 401. One side of the positioning block 402 is elastically connected to the guide groove 404 through a return spring 405.

[0026] In this type of anti-theft power meter, when the anti-theft door 201 moves upward until the plug-in block 4 is fully plugged into the plug-in slot on the top of the anti-theft housing 2, the positioning block 402 will be pushed by the return spring 405 in the guide groove 404 and plugged into the positioning slot 401 opened inside the plug-in block 4. Under the thread action of the drive motor 3 driving the adjusting screw 301 and the adjusting rod 302, the anti-theft door 201 is limited a second time.

[0027] exist Figure 3 and Figure 4 In the middle: one side of the positioning block 402 is connected to one end of the pull rope 403, and the other end of the pull rope 403 passes through the guide groove 404 and is bolted to the winding roller 406. The middle part of the winding roller 406 is connected to the adjusting screw 301 for adjusting the position of the positioning block 402.

[0028] In this type of anti-theft power meter, when the drive motor 3 drives the adjusting screw 301 to rotate via the coupling, it will drive the winding roller 406 to rotate, winding the pull rope 403. In turn, the pull rope 403 will drive the positioning block 402 to move into the guide groove 404, so as to avoid the positioning block 402 interfering with the downward movement of the anti-theft door 201. When the anti-theft door 201 moves upward and is fully inserted into the insertion groove, the winding roller 406 will release the pull on the positioning block 402 via the pull rope 403, so that the positioning block 402 can be smoothly inserted into the positioning groove 401 under the action of the return spring 405.

[0029] exist Figure 3 , Figure 4 , Figure 6 and Figure 7 In the middle: a movable block 5 is slidably inserted into the positioning groove 401, and a reserved groove 501 is opened inside the anti-theft shell 2. The outer side of the movable block 5 is inserted into the reserved groove 501 to limit the anti-theft door 201 again. One side of the movable block 5 abuts against the positioning block 402.

[0030] In this type of anti-theft power meter, when the positioning block 402 is inserted into the positioning groove 401 under the pushing action of the reset spring 405, it will push the movable block 5, which is slidably connected inside the positioning groove 401, to be inserted into the reserved groove 501, thereby limiting the anti-theft door 201 again. When the anti-theft door 201 needs to move downward, the movable block 5 is pushed into the positioning groove 401 through the reserved groove 501 until the movable block 5 is completely disengaged from the reserved groove 501 and the positioning block 402 is squeezed out of the positioning groove 401, at which point the drive motor 3 can be started to drive the anti-theft door 201 downward.

[0031] exist Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In the middle: both sides of the anti-theft shell 2 are welded with slide rails 6, and both sides of the anti-theft door 201 are provided with slide grooves 601. The two slide grooves 601 are connected to guide rails 602 inside. The two slide rails 6 are slidably connected to the slide grooves 601 on the outside. The two guide rails 602 are slidably connected to the grooves inside the slide rails 6, which is used to improve the stability of the anti-theft door 201 when it moves.

[0032] This type of anti-theft electricity meter features an anti-theft door 201 that moves along the slide rails 6 on both sides of the anti-theft housing 2 via the sliding grooves 601 and guide rails 602 on both sides. This effectively enhances the stability of the anti-theft door 201 during use. Furthermore, the plug-in design reduces the number of external installation parts, making it difficult to disassemble the anti-theft door 201 on the outside of the anti-theft housing 2. This, in turn, ensures the safety of the electricity meter body 1 inside the anti-theft housing 2.

[0033] exist Figure 2 , Figure 5 and Figure 6 In the middle: the security door 201 has a reserved groove 2 7 inside, and the outer side of the security door 201 is arc-shaped, and the reserved groove 2 7 is located on the inner side of the arc-shaped surface of the security door 201.

[0034] This type of anti-theft electricity meter features an arc-shaped anti-theft door 201 that allows the door to disperse force to both sides when impacted, achieving a pressure relief effect. In addition, the pre-reserved groove 7 allows for slight deformation upon impact to offset the impact force, enhancing the overall force-dissipating effect of the anti-theft door 201 and reducing the likelihood of thieves disassembling or breaking the anti-theft door 201.

[0035] Working principle: When using this anti-theft electricity meter, the movable block 5 is pushed from the reserved slot 501 to the positioning slot 401 until it completely disengages from the reserved slot 501 and pushes the positioning block 402 out of the positioning slot 401. Then, the drive motor 3 is controlled by the operation box 202. The output of the drive motor 3 drives the adjusting screw 301 to rotate via a coupling. Through the threaded action with the adjusting rod 302, the adjusting rod 302 moves vertically, thereby causing the anti-theft door 201 welded to the adjusting rod 302 to move downwards, opening the operating channel. Simultaneously, the rotation of the adjusting screw 301 drives the winding roller 406 to rotate, winding the pull rope 403. The pull rope 403 then drives the positioning block 402 to move into the guide groove 404, allowing the user to operate the electricity meter body 1. After completing the operation of the power meter body 1, start the drive motor 3. The output end of the drive motor 3 drives the adjusting screw 301 to rotate through the coupling. Through the thread action with the adjusting rod 302, the adjusting rod 302 moves vertically, thereby driving the anti-theft door 201 welded to the adjusting rod 302 to move upward along the slide rail 6 through the inner slide groove 601 and guide rail 602 to close the operation channel. When the anti-theft door 201 moves upward until the plug block 4 is fully plugged into the plug groove at the top of the anti-theft housing 2, the winding roller 406 will release the pull on the positioning block 402 through the pull rope 403, so that the positioning block 402 can be smoothly plugged into the positioning groove 401 under the action of the return spring 405. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
