[0028] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example
[0029] An anti-theft electricity metering box includes a box shell 1. An installation block 2 is fixedly connected to one side of the inside of the box shell 1. An anti-theft box 3 is inserted into the surface of the installation block 2. An insert block 4 is embedded and fixedly connected to one side of the anti-theft box 3. A lock groove 5 is opened on the top of the insert block 4. A rotating rod 6 is rotatably installed inside the installation block 2. A lock block 7 that matches the lock groove 5 is fixedly connected to the surface of the rotating rod 6. Torsion springs 8 are sleeved at both ends of the surface of the rotating rod 6. A slot 11 that matches the lock block 7 is opened inside the installation block 2.
[0030] The specific usage process is as follows: First, the relay switch 17 is fixedly installed inside the anti-theft box 3. Under the protection of the anti-theft box 3, the wire cannot be connected to the relay switch 17 from the outside, thus achieving the purpose of preventing electricity theft. It should be noted that the power meter 19 and other components can also be protected in this way. Furthermore, since the lever 9 can only be operated from inside the anti-theft box 3, the anti-theft box 3 is also difficult to remove, preventing the direct removal of the anti-theft box 3. This sets up layers of restrictions on electricity theft, preventing its occurrence. Therefore, by adding an anti-theft structure outside important electrical components, the important electrical components are individually protected against theft, increasing the difficulty of electricity theft and making it difficult for wires to be connected to important components, thereby limiting electricity theft. This system can delay theft, giving users ample reaction time to respond and reduce property loss, thus achieving the purpose of theft prevention and providing convenience for users' work. Before installing the anti-theft box 3, all relay switches 17 can be installed inside the anti-theft box 3. Then, the wires connected to the relay switches 17 are guided out through the opening on the anti-theft box 3. Next, the anti-theft box 3 is aligned with the mounting block 2 inside the box shell 1 and snapped in place. At the same time, the lever 9 should be aligned with the notch 14 and inserted into the anti-theft box 3. Then, the pin 12 is inserted into the slot 13 for positioning. The mounting slot 15 is designed so that when the anti-theft box 3 is installed, it will snap onto the surface of the mounting block 2, and the mounting block 2 is also inserted into the mounting slot 15. This ensures the anti-theft box 3 is securely fixed. The installation is performed to ensure that the lock block 7 can quickly align with the lock groove 5, thus completing the installation quickly and providing convenience for the user. When installing the anti-theft box 3, the pin 12 can be inserted into the slot 13, thus limiting and positioning the installation of the anti-theft box 3, providing assistance for the lock block 7 to be inserted into the lock groove 5, and providing convenience for the user's installation. At this time, the lock block 7 will also align with the lock groove 5 and be inserted into the lock groove 5, thereby fixing the anti-theft box 3 onto the mounting block 2, completing the installation of the anti-theft box 3. During the process of the lock block 7 being inserted into the lock groove 5, it will first be squeezed upward and flipped by the insert block 4, and then the rotating rod 6 will also rotate in the mounting block 2, while twisting the torsion spring 8. At the same time, the lever 9 will also follow the rotation of the lever 6 in the anti-theft box 3. The anti-theft box 3 and the insert block 4 move accordingly until the locking block 7 is fully inserted into the lock groove 5. At this time, the torsion spring 8 returns to its original state, thereby driving the rotating rod 6 and the locking block 7 to rotate and reset. Finally, the locking block 7 is fully engaged in the lock groove 5, completing the installation of the anti-theft box 3 and the relay switch 17. To unlock, the box door 16 is unlocked and opened. The lever 9 is lifted upward from inside the anti-theft box 3, which in turn drives the rotating rod 6 and the locking block 7 to rotate upward. At the same time, the locking block 7 moves out of the lock groove 5 to unlock. Then, the user can directly remove the anti-theft box 3 from the mounting block 2 to complete the disassembly, thus providing convenience for the user's subsequent maintenance work. This allows the metering box to not only meet the anti-theft requirements but also facilitate user maintenance, providing convenience for the user's work and use.Two fixing blocks 10 are respectively fixedly installed on both sides inside the mounting block 2, and are used to install the rotating rod 6. One end of the torsion spring 8 is also fixed to the corresponding fixing block 10, thus enabling the torsion spring 8 to perform its function. After the rotating rod 6 is used, it drives the rotating rod 6 and the locking block 7 to reset, providing convenience for the user's disassembly and assembly. The lever 9 is used to control the movement of the rotating rod 6 and the locking block 7. The lever 9 is set inside the anti-theft box 3 through the notch 14, so it can only be operated from inside the anti-theft box 3, preventing operation from the outside and thus playing an anti-theft role, preventing the anti-theft box 3 from being arbitrarily removed, and providing convenience for the user's work. The box door 16 covers and locks the anti-theft box 3, protecting the relay switch 17 inside the anti-theft box 3 from being stolen. The relay switch 17 and the power meter 19 are connected by wires through an opening in the anti-theft box 3, ensuring the normal operation of the meter and providing convenience for the user's work.
[0031] Both sides of the mounting block 2 are fixedly connected to the fixing blocks 10. The rotating rod 6 is rotatably installed between the two fixing blocks 10. The two ends of the torsion spring 8 are fixedly connected to the fixing blocks 10 and the locking block 7, respectively.
[0032] Specifically, the fixing blocks 10 are set up such that two fixing blocks 10 are respectively fixedly installed on both sides inside the mounting block 2 and used to install the rotating rod 6. At the same time, one end of the torsion spring 8 is also fixed on the corresponding fixing block 10. In this way, the torsion spring 8 can realize its function, thereby driving the rotating rod 6 and the locking block 7 to reset after the rotating rod 6 is used, providing convenience for the user's disassembly and assembly work.
[0033] One end of the rotating rod 6 extends through the corresponding fixing block 10 to the outside of the mounting block 2 and is fixedly installed with a lever 9. One end of the lever 9 extends into the anti-theft box 3. A notch 14 adapted to the lever 9 is opened on one side of the anti-theft box 3.
[0034] Specifically, the lever 9 and notch 14 are designed so that the lever 9 controls the operation of the rotating rod 6 and the locking block 7. The lever 9 is set inside the anti-theft box 3 through the notch 14, so the lever 9 can only be operated from inside the anti-theft box 3, thereby preventing the lever 9 from being operated from the outside and thus playing an anti-theft role. This prevents the anti-theft box 3 from being arbitrarily removed and provides convenience for users.
[0035] The anti-theft box 3 has a mounting groove 15 on one side that is compatible with the mounting block 2, and slots 13 are provided at both ends of one side of the mounting groove 15.
[0036] Specifically, the mounting slot 15 is designed so that when the anti-theft box 3 is installed, it will be snapped onto the surface of the mounting block 2, and the mounting block 2 will also be inserted into the mounting slot 15. This allows for the positioning of the anti-theft box 3 and ensures that the lock block 7 can be quickly aligned with the lock slot 5, thereby quickly completing the installation work and providing convenience for the user's work.
[0037] Both ends of the bottom side of the mounting block 2 are fixedly connected with pins 12, and the end of the pin 12 away from the mounting block 2 is inserted into the corresponding slot 13.
[0038] Specifically, the design of the pin 12 and the slot 13 ensures that the pin 12 can be inserted into the slot 13 during the installation of the anti-theft box 3, thereby limiting and positioning the installation of the anti-theft box 3, assisting the lock block 7 in being inserted into the lock groove 5, and providing convenience for the user's installation work.
[0039] A door 16 is movably mounted on one side of the anti-theft box 3 via a pivot rod. A mechanical lock is installed through one side of the door 16. The door 16 is locked to the anti-theft box 3 by the mechanical lock. Multiple relay switches 17 are fixedly installed inside the anti-theft box 3.
[0040] Specifically, the door 16 and relay switch 17 are designed so that the door 16 covers and locks onto the anti-theft box 3, protecting the relay switch 17 inside the anti-theft box 3 and preventing it from being stolen. The relay switch 17 and the power meter 19 are connected by wires through an opening in the anti-theft box 3, thus ensuring the normal operation of the meter box and providing convenience for users.
[0041] The inner cavity of the enclosure 1 is fixedly installed with a power meter 19 located above the anti-theft box 3. A heat dissipation vent 18 is opened on one side of the enclosure 1, and a door 20 is hinged to one side of the enclosure 1.
[0042] Specifically, the heat dissipation vent 18, the power meter 19, and the second door 20 are designed so that the second door 20 is closed and locked onto the casing 1, making it impossible to open without a key. The power meter 19 is used to display power data for users to monitor at any time. The heat dissipation vent 18 is used for heat dissipation to prevent internal components from malfunctioning due to overheating and to ensure the normal operation of the metering box. It should be noted that one side of the anti-theft box 3 overlaps with the heat dissipation vent 18, so it can also dissipate heat through the heat dissipation vent 18, providing convenience for users.
[0043] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
