Description

Technical Field

[0001] The present invention relates to an anti-stealing electricity device, and particularly to an electricity meter device with an anti-stealing electricity function, belonging to the technical field of electrical equipment. Background Art

[0002] In industrial production, as a device for measuring power consumption, an electricity meter is often used to monitor and record the power consumed by different devices and production lines, and then accurately calculate the power consumption of users. According to the power consumption, cost settlement is carried out to ensure the fairness and reasonableness of power supply, which is crucial for managing energy costs, optimizing energy use efficiency, and conducting production cost analysis.

[0003] However, the existence of electricity stealing behavior has a great adverse impact on the monitoring and measurement of the electricity meter. Therefore, anti-stealing electricity treatment is very important. Currently, one of the common ways of anti-stealing electricity treatment is to prevent the metering box door from being illegally opened. After retrieval, the Chinese patent publication number: CN212514739U, which relates to the technical field of electrical equipment, discloses a remote anti-stealing electricity device. It is recorded in the patent specification that "the locking mechanism consists of several locking bolts. The head of the locking bolt is provided with a jack, and the jack includes a first guiding hole and a second guiding hole partially overlapping with the first guiding hole. The depth of the first guiding hole is greater than that of the second guiding hole. That is, the jack of the locking bolt is of an irregular shape, and the locking bolt is installed in the screw hole in a sunk manner. Lawbreakers need to be equipped with specific tools to loosen the locking bolt, increasing the difficulty of opening the electricity meter box and improving the anti-stealing electricity performance of the electricity meter box." In the above embodiment, by designing the jack of the locking bolt to be of an irregular shape, the anti-stealing electricity is achieved by requiring lawbreakers to be equipped with specific tools to open it. However, it does not consider the situation that lawbreakers only need to insert the tool into the jack for a part and then can rotate the locking bolt to open the electricity meter box, resulting in poor anti-stealing electricity function of the device. Therefore, an electricity meter device with an anti-stealing electricity function is proposed. Summary of the Invention

[0004] In order to solve the deficiencies of the above-mentioned technology, the present invention provides an electricity meter device with an anti-stealing electricity function.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an electricity meter device with an anti-stealing electricity function, including an electricity meter box body, a box cover hinged to the front side of the electricity meter box body, and an electricity meter installed in the electricity meter box body.

[0016] As a further description of the above technical solution:

[0017] A limiting protrusion is formed at a position in the lock hole cavity facing the unlocking hole, so that the lock hole cavity has a special-shaped shape to meet the quick and accurate unlocking use of the L-shaped unlocking member;

[0018] The protruding height of the limiting protrusion towards the unlocking hole is not higher than the position of the sliding plate when the first spring is in an uncompressed natural initial state; the overall width of the L-shaped unlocking member is not greater than the width of the unlocking hole. The L-shaped unlocking member is inserted into the lock hole cavity from the unlocking hole. When the L-shaped unlocking member abuts against the limiting protrusion, the unlocking member is pushed towards the sliding plate direction so that the L-shaped unlocking member abuts against the sliding plate, and then the L-shaped unlocking member pushes the sliding plate so that the clamping plate disengages from the clamping hole of the insertion plate, and the box cover and the electric meter box body are in an open state.

[0019] As a further description of the above technical solution:

[0020] The side wall of the keyhole cavity where the unlocking hole is located is an outer protective wall;

[0021] When the box cover and the electric meter box body are in a locked state, the insertion plate and the sliding plate are both shielded and protected by the outer protective wall.

[0022] As a further description of the above technical solution:

[0023] A monitoring and alarm component for transmitting signals to a distance is arranged inside the electric meter box body.

[0032] The telescopic support member includes a receiving column, a stress column and a second spring;

[0033] The stress column is fixedly connected with the clamping plate, and the stress column is slidably arranged in the receiving column through a damping structure, and the spring is sleeved outside the receiving column and the stress column and is limited between the clamping plate and the inner wall of the receiving hole;

[0034] One end of the second spring is fixedly connected with the clamping plate, and the other end is fixedly connected with the inner wall of the receiving hole.

[0038] The present invention discloses an electric meter device with an anti-stealing electricity function. Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. In the present invention, the anti-stealing locking mechanism is a hidden structure. Illegal persons cannot view the structural features of the anti-stealing locking mechanism from the outside, so they cannot prepare tools to open the box cover, fundamentally solving the problem that the existing electric meter box cover is easily illegally opened.

[0040] 2. In the present invention, through the engagement between the clamping plate of the anti-stealing locking mechanism and the engagement holes of the insertion plate, the box cover and the meter box body can be closely fitted and locked without external force. Moreover, through the design of the lock hole cavity and the unlocking hole, only an L-shaped plate with a specific shape can press the sliding plate to open the box cover from the outside of the electric meter box. Therefore, a high-level anti-stealing electricity effect can be achieved.

[0041] 3. In the present invention, the lock hole cavity is designed with a special shape to form a limiting protrusion structure, so that the L-shaped unlocking member can quickly and accurately reach the unlocking position. Therefore, while the anti-stealing locking mechanism achieves a high-level anti-stealing electricity effect, it will not cause inconvenient interference to the staff when opening the box cover from the outside.

[0042] 4. In the present invention, through the setting of monitoring and alarm components such as cameras, the personnel entering the inside of the electric meter box can be observed. When the personnel entering the inside of the electric meter box are not staff members, the alarm will sound, and the observed image will be transmitted to a remote terminal through a signal transmitter and stored, thereby further improving the anti-stealing electricity level of this electric meter device.

[0043] 5. In the present invention, through the setting of the telescopic support member and the clamping plate, the lines entering the accommodating holes can be clamped and fixed, thereby preventing the phenomenon that too many lines entering the inside of the electric meter box are wound together, and improving the safety of this electric meter device to a certain extent.

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] Embodiment 1:

[0053] This embodiment discloses an electricity meter device with an anti-stealing electricity function, and the overall structure of the electricity meter device is set as Figure 1 shown, including a meter box body 1. The meter box body 1 serves as the main structure support of the entire device, meeting the installation requirements of other structural components. First, a box cover 7 is hinged at the front side position of the meter box body 1. At the same time, a meter 20 for measuring the electricity consumption is installed inside the meter box body 1.

[0054] Preferably, as Figure 4 shown, the meter 20 is installed on the back inner wall of the meter box body 1.

[0055] Considering the current situation that the existing meter box cover is easily opened by lawbreakers, this embodiment modifies the locking structure between the meter box body 1 and the box cover 7, and designs a hidden anti-stealing locking mechanism, as Figure 2 and Figure 3 shown. The specific setting of the anti-stealing locking mechanism is as follows:

[0056] First, a lock hole cavity 2 is provided at the edge position of the front side wall of the electric meter box body, relying on this lock hole cavity 2 to provide a spatial site for the setting of the anti-theft locking mechanism, so that the anti-theft locking mechanism is set at the place where the lock hole cavity is located;

[0057] Secondly, the anti-theft locking mechanism includes a sliding rod 3, a first spring 4, a sliding plate 5, a clamping plate 6 and an insertion plate 8;

[0058] Among them, the sliding rod 3 is a columnar rod body, the sliding rod 3 is horizontally distributed in the lock hole cavity 2 and is fixedly connected to the side wall of the electric meter box body 1 where the lock hole cavity 2 is located at one end, so that the sliding rod 3 is a fixed structure for supporting and guiding the movement of the sliding plate 5.

[0059] The sliding plate 5 is slidably arranged on the sliding rod 3 by means of a sliding hole structure. At the same time, a clamping plate 6 is fixedly arranged on one side of the sliding plate 5.

[0060] The first spring 4 is sleeved on the sliding rod 3 and is limited between the sliding plate 5 and the side wall of the electric meter box body 1 where the lock hole cavity 2 is located. One end of the first spring 4 is fixedly connected to the side wall of the lock hole cavity 2, and the other end is fixedly connected to the sliding plate 5. The first spring 4 enables the sliding plate 5 to automatically return to the initial position when there is no external force, assisting in locking or unlocking the box cover 7 and the electric meter box 1.

[0061] The clamping plate 6 is a toothed structure, which is fixed in the middle of the right side of the sliding plate 5 and can move synchronously with the sliding plate 5.

[0062] The insertion plate 8 is fixedly connected to the back side of the box cover 7 and is located at the place where the lock hole cavity 2 is located. A clamping hole 9 adapted to the clamping plate 6 is provided on the insertion plate 8; when the clamping plate 6 is clamped and inserted into the clamping hole 9, the box cover 7 and the electric meter box body 1 are in a locked state. Similarly, when the clamping plate 6 disengages from the clamping hole 9, the box cover 7 and the electric meter box body 1 are in an unlocked and open state.

[0063] To achieve unlocking and opening, as shown in Figure 2 and Figure 3 , an unlocking hole 21 communicating with the lock hole cavity 2 is provided on the outer side wall of the electric meter box body 1. The unlocking hole 21 is used for inserting a specific-shaped L-shaped unlocking member to achieve unlocking.

[0064] When unlocking and opening, a specific-shaped L-shaped unlocking member needs to be used. The overall width of the L-shaped unlocking member is not greater than the width of the unlocking hole 21, so that the L-shaped unlocking member can enter the lock hole cavity 2 from the unlocking hole 21.

[0065] Moreover, the side wall of the lock hole cavity 2 where the unlocking hole 21 is located is an outer protective wall 22; when the box cover 7 and the electric meter box body 1 are in a locked state, the insertion plate 8 and the sliding plate 5 are both shielded and protected by the outer protective wall 22.

[0066] Thus, for the electricity meter device with anti-stealing function in this embodiment, its working principle is as follows:

[0067] First of all, the box cover 7 is locked with the clamping plate 6 of the electricity meter box body 1 through the insertion plate 8 by a clamping mechanism. When in the locked state, the first spring 4 is in the natural initial state without being compressed. The first spring 4 presses against the sliding plate 5 to insert the clamping plate 6 into the clamping hole 9 of the insertion plate 8. Since the sliding rod 3 is combined with the first spring 4, a slidable mechanism that can rebound is provided for the sliding plate 5, enabling the precise docking of the clamping plate 6 and the clamping hole 9 on the insertion plate 8. The clamping hole 9 on the insertion plate 8 is precisely docked with the clamping plate 6 on the sliding plate 5 inside the electricity meter box. The sliding plate 5 realizes the rebounding function through the built-in sliding rod 3 and the first spring 4, ensuring that the insertion plate 8 remains in the locked state without external force. This design ensures the tight fit between the box cover 7 and the electricity meter box 1 and effectively prevents unauthorized opening.

[0068] Secondly, to unlock and open the box cover 7 relative to the electricity meter box body 1, the cooperation between the insertion plate 8 and the clamping plate 6 of the electricity meter box body 1 is also utilized to make the clamping plate 6 disengage from the clamping hole 9 of the clamping plate 6. An L-shaped unlocking member with a specific shape is equipped. The L-shaped unlocking member is inserted into the unlocking hole 21 on the outer side wall of the electricity meter box body 1, and then the L-shaped unlocking member is pushed towards the direction of the sliding plate 5 so that the L-shaped unlocking member can contact the sliding plate 5; then, a thrust is applied by the L-shaped unlocking member, and further the sliding plate 5 is pushed to compress the first spring 4 until the clamping plate 6 disengages from the clamping hole 6 of the insertion plate 8, and then the box cover 7 can be opened.

[0069] Similarly, when the box cover 7 needs to be closed again, a thrust is applied to the sliding plate 5 by the L-shaped unlocking member to compress the first spring 4, the box cover 7 is closed, and the thrust applied by the L-shaped unlocking member is removed. The first spring 4 will produce a rebounding sliding mechanism during the restoration of deformation, and then the clamping plate 6 is inserted into the clamping hole 9 on the insertion plate 8 again to realize the closing and locking of the box cover 7.

[0070] Thus, for the electricity meter device with anti-stealing function disclosed in this embodiment, through the innovative design of the locking structure between the box cover 7 and the electricity meter box body 1, the electricity meter device has a higher level of anti-stealing performance. Its anti-stealing advantages are mainly reflected in the following two points:

[0071] First, since the anti-stealing locking mechanism is hidden in the lock hole cavity 2, lawbreakers cannot view the internal anti-stealing locking mechanism only from the unlocking hole 21. Therefore, this greatly increases the difficulty for lawbreakers to open the box cover.

[0072] Second, through the engagement between the clamping plate 6 and the engagement hole 9 of the insertion plate 8, the anti-theft locking mechanism can tightly fit and lock the lid 7 and the meter box body 1 without external force. Moreover, only an L-shaped plate with a specific shape can press the sliding plate 5 to open the lid 7 from the outside of the meter box body 1. Therefore, the opening method of the lid 7 is specific and skillful, further increasing the difficulty for lawbreakers to open the lid. This mechanism not only provides physical security but also prevents the illegal use of ordinary tools through its unique structural design. Thus, the anti-theft effect of the meter device in this embodiment is excellent.

[0073] Embodiment 2:

[0074] This embodiment discloses a meter device with an anti-theft function, and its overall structure is arranged as Figure 1 shown, including a meter box body 1, a lid 7 hinged to the front side of the meter box body 1, and a meter 20 installed in the meter box body 1.

[0075] To solve the problem that the lid of the existing meter box is easily opened by lawbreakers, for the meter device with an anti-theft function disclosed in this embodiment, a hidden anti-theft locking mechanism with a high anti-theft level is used to achieve locking connection between the lid 7 and the meter box body 1.

[0076] As Figure 2 and Figure 3 shown, a lock hole cavity 2 is opened at the edge position of the front side wall of the meter box body, and the anti-theft locking mechanism is arranged at the location of the lock hole cavity;

[0077] The anti-theft locking mechanism includes the following structural components, namely: a sliding rod 3, a first spring 4, a sliding plate 5, a clamping plate 6, and an insertion plate 8;

[0078] The sliding rod 3 is horizontally distributed and fixed in the lock hole cavity, and is used to support and guide the movement of the sliding plate 5.

[0079] The first spring 4 is sleeved on the sliding rod 3, and one end of the first spring 4 is fixedly connected to the sliding plate 5 and the other end is fixedly connected to the side wall of the lock hole cavity. The first spring 4 enables the sliding plate 5 to automatically return to the initial position without external force, assisting in locking or unlocking the lid 7 and the meter body 1.

[0080] The clamping plate 6 is fixed on the sliding plate 5 and can move synchronously with the sliding plate 5.

[0081] The insertion plate 8 is a structural component fixed on the lid 7, and an engagement hole 9 adapted to the clamping plate 6 is opened on the insertion plate 8.

[0082] Thus, the engaging plate 6 is engaged with the inside of the engaging hole 9. At the same time, the sliding rod 3 and the first spring 4 are used in combination to provide a resilient sliding mechanism for the sliding plate 5, and the sliding plate 5 drives the engaging plate 6 to move directionally, which helps to accurately align the engaging plate 6 with the engaging hole 9 on the insertion plate 8. This design enables the box cover 7 to fit tightly with the electric meter box body 1 and prevents unauthorized opening.

[0083] Further, to enable the external opening of the box cover 7, as Figure 2 and Figure 3 shown, an unlocking hole 21 communicating with the lock hole cavity 2 is provided on the outer side wall of the electric meter box body 1. At the same time, an L-shaped unlocking member with a specific shape is equipped. The overall width of the L-shaped unlocking member is not greater than the width of the unlocking hole 21, so that the L-shaped unlocking member can enter the lock hole cavity 2 from the unlocking hole 21.

[0084] The difference from the first embodiment is that, to enable the L-shaped unlocking member to accurately contact the sliding plate to complete the unlocking operation, as Figure 3 shown, the electric meter device with anti-stealing electricity function disclosed in this embodiment designs the lock hole cavity 2 into a special-shaped shape to meet the efficient and accurate unlocking use of the L-shaped unlocking member.

[0085] Specifically: a limiting protrusion 23 is formed at the position of the lock hole cavity 2 facing the unlocking hole 21. The limiting protrusion 22 protrudes into the lock hole cavity 2 to make the lock hole cavity 2 in a special-shaped shape. The protruding height of the limiting protrusion 23 facing the unlocking hole 21 should not be higher than the position of the sliding plate 5 when the first spring 4 is in the natural initial state without compression, so that the L-shaped unlocking member can just act on the sliding plate 5 when pushed in the direction of the sliding plate 5.

[0086] Due to the specific design of the protruding height of the limiting protrusion 23 facing the unlocking hole 21 and the specific design of the length of the first spring 4, when the L-shaped unlocking member abuts against the limiting protrusion 23, it is at the correct unlocking position. Then, when the L-shaped unlocking member is pushed in the direction of the sliding plate 5, it can just be located at the gap between the sliding plate 5 and the insertion plate 8. Then, by pushing the L-shaped unlocking member further, the sliding plate 5 can be pushed.

[0087] Thus, for the electric meter device with anti-stealing electricity function in this embodiment, its working principle is:

[0088] First, the principle of the locking state between the box cover 7 and the meter box body 1 is the same as that in the first embodiment. The locking is achieved through the engagement mechanism by inserting the insertion plate 8 into the engagement hole 9 of the engaging plate 6. When in the locked state, the first spring 4 is in its natural initial state without being compressed. The first spring 4 presses against the sliding plate 5 to insert the engaging plate 6 into the engagement hole 9 of the insertion plate 8. Since the sliding rod 3 is combined with the first spring 4, a sliding mechanism that can rebound is provided for the sliding plate 5, enabling the precise docking of the engaging plate 6 with the engagement hole 9 on the insertion plate 8. The engagement hole 9 on the insertion plate 8 is precisely docked with the engaging plate 6 on the sliding plate 5 inside the meter box. The sliding plate 5 realizes the rebound function through the built-in sliding rod 3 and the first spring 4, ensuring that the insertion plate 8 remains in the locked state without external force. This design ensures the tight fit between the box cover 7 and the meter box 1, effectively preventing unauthorized opening.

[0089] The difference from the first embodiment lies in that there are certain differences in the unlocking and opening process. For the electricity meter device with the anti-stealing function in this embodiment, when performing the unlocking and opening operation of the box door 7 externally, a specific-shaped L-shaped unlocking member is used. The L-shaped unlocking member is inserted into the unlocking hole 21 on the outer side wall of the meter box body 1. As the L-shaped unlocking member penetrates deeper, when the L-shaped unlocking member abuts against the limit protrusion 23, the unlocking member is then pushed towards the sliding plate 5 direction so that the L-shaped unlocking member can contact the sliding plate 5. At this time, the L-shaped unlocking member is exactly located at the gap between the sliding plate 5 and the insertion plate 8. Then, a thrust is applied by the L-shaped unlocking member to push the sliding plate 5 to compress the first spring 4 until the engaging plate 6 disengages from the engagement hole 6 of the insertion plate 8, and then the box cover 7 can be opened.

[0090] Similarly, when the box cover 7 needs to be closed again, a thrust is applied to the sliding plate 5 by the L-shaped unlocking member to compress the first spring 4, close the box cover 7, and remove the thrust applied by the L-shaped unlocking member. The first spring 4 will generate a rebounding sliding mechanism during the recovery of deformation, and then the engaging plate 6 is inserted into the engagement hole 9 on the insertion plate 8 again to achieve the closing and locking of the box cover 7.

[0091] Therefore, for the electricity meter device with the anti-stealing function disclosed in this embodiment, while using the hidden anti-stealing locking mechanism with a higher level of anti-stealing performance to realize the locking connection between the box cover 7 and the meter box body 1, the convenience and efficiency of authorized personnel to open the anti-stealing locking mechanism are also considered. The lock hole cavity 2 is designed with a special shape, and the limit protrusion 23 in the lock hole cavity forms a special-shaped structure. Cooperating with the anti-stealing locking mechanism in this embodiment, the L-shaped unlocking member reaches the correct unlocking position when touching the limit protrusion, enabling authorized personnel to quickly and accurately complete the operation of unlocking and opening the box door 7.

[0092] Although the design of the above keyhole cavity 2 enables authorized personnel to easily complete the unlocking and opening operations, for lawbreakers, since the structural features of the anti-theft locking mechanism cannot be viewed from the outside, they have no idea how to open the box door. Moreover, the electric meter device with the function of preventing electricity theft in this embodiment requires a specific-shaped L-shaped unlocking piece to complete the unlocking and opening operations of the box door 7. This means that lawbreakers cannot open the box door 7 with ordinary tools alone by guessing. Therefore, this embodiment has excellent anti-theft electricity performance and effectively ensures the normal functioning of the monitoring and measurement functions of the electric meter.

[0093] Embodiment Three:

[0094] This embodiment discloses an electric meter device with the function of preventing electricity theft, and the overall structure is set as Figure 1 shown, including an electric meter box body 1 and a box cover 7 hinged to the front side of the electric meter box body 1; at the same time, as Figure 4 shown, an electric meter 20 is installed in the electric meter box body 1.

[0095] To solve the problem that the box cover of the existing electric meter box is easily opened by lawbreakers, for the electric meter device with the function of preventing electricity theft disclosed in this embodiment, first, the structure of the locking connection between the box cover 7 and the electric meter box body 1 is modified, and a hidden anti-theft locking mechanism with a high anti-theft level is designed; second, a monitoring and alarm component for transmitting signals to a distance is also provided inside the electric meter box body 1. The monitoring and alarm component is linked with a remote monitoring center. When it is found that the person opening the box door of the electric meter box is not a staff member, image data can be collected and an alarm can be issued, thereby further improving the anti-theft electricity level of this electric meter device.

[0096] First, for the anti-theft locking mechanism, the same structural form as in Embodiment One or Embodiment Two is adopted. This anti-theft locking mechanism includes: a sliding rod 3, a first spring 4, a sliding plate 5, a clamping plate 6, and an insertion plate 8;

[0097] Among them, the insertion plate 8 is fixed on the box cover 7, and a clamping hole adapted to the clamping plate 6 is provided on the insertion plate 8; the clamping plate 6 is fixed on one side of the sliding plate 5 and can move synchronously with the sliding plate 5; the sliding plate 5 can slide along the sliding rod 3; the sliding rod 3 is fixed in the keyhole cavity 2, and the keyhole cavity 2 provides a fixed setting site for the sliding rod 3; the first spring 4 is sleeved on the sliding rod 3 and is located between the sliding plate 5 and the inner wall of the keyhole cavity 2. The first spring 4 provides a rebounding sliding mechanism, enabling the sliding plate 5 to automatically return to the initial position without external force, and assisting in realizing the locking or unlocking between the box cover 7 and the electric meter box body 1. Thus, when the clamping plate 6 is clamped and inserted into the clamping hole 9, the box cover 7 and the electric meter box body 1 are in a locked state. Similarly, when the clamping plate 6 disengages from the clamping hole 9, the box cover 7 and the electric meter box body 1 are in an unlocked and open state.

[0098] For the specific structural settings and principles of the anti-theft locking mechanism, refer to the descriptions in Embodiment 1 or Embodiment 2, and details will not be elaborated here.

[0099] For the electric meter device with anti-theft power stealing function disclosed in this embodiment, it is further provided with a monitoring and alarm component to enhance the anti-theft power stealing performance. The monitoring and alarm component includes a camera 14, an alarm 13 and a signal transmitter 12;

[0100] As Figure 4 shown, the camera 14 and the alarm 13 are both installed on the inner side wall of the electric meter box body 1 where the lock hole cavity 2 is located; the signal transmission device 12 is installed on the back inner wall of the electric meter box body 1;

[0101] The camera 14 is a commercially available network camera. After the box cover 7 is opened, the camera 14 collects the intrusion images or video data of opening the box cover 7 and transmits them to the signal transmitter 12. The signal transmitter 12 is connected to the remote monitoring center. Then, the signal transmitter 12 sends the monitored data to the remote monitoring center. The remote monitoring center processes the monitored image data. When it is found that the person opening the box cover 7 is not a staff member, the remote monitoring center transmits the processed intrusion signal to the alarm 13 to control the alarm 13 to sound an alarm. At the same time, the staff at the remote monitoring center can also learn about the illegal intrusion situation, and the monitoring data stored in the remote monitoring center can also be used as strong evidence to identify the lawbreakers.

[0102] In summary, for the electric meter device with anti-theft power stealing function disclosed in this embodiment, it has the following technical advantages:

[0103] Since the box cover 7 and the electric meter box body 1 adopt a hidden anti-theft locking mechanism to achieve locking connection through a clamping mechanism, it is extremely difficult for illegal personnel to open the box cover 7 externally. Therefore, the electric meter device with anti-theft power stealing function in this embodiment has a high anti-theft power stealing level.

[0104] On the basis of the anti-theft locking mechanism as the first-level anti-theft protection line, a monitoring and alarm component is further set. The monitoring and alarm component serves as the second-level anti-theft power stealing protection line. Once the electric meter box cover 7 is opened in an unauthorized manner or attempts to be damaged, the internal monitoring system is immediately activated, the camera 14 starts to work, and the internal environment of the electric meter box is monitored in real time. Once abnormal activities are detected, the camera 14 will trigger the alarm 13 to sound an alarm. At the same time, the signal transmitter 12 sends the captured images and alarm information to the remote monitoring center. Therefore, it is possible to respond in a timely manner to possible power stealing behaviors.

[0105] Embodiment 4:

[0106] This embodiment discloses an electric meter device with an anti-stealing electricity function. Based on the structure of the electric meter device with the anti-stealing electricity function disclosed in Embodiment 3, this embodiment further optimizes the internal space design of the electric meter box body 1, sets the arrangement and storage of wires, so as to reduce the maintenance difficulty and potential safety risks of the electric meter device.

[0107] As Figure 4 and Figure 5 shown, a plurality of receiving holes 15 are formed in the inner wall of the back side of the electric meter box body 1, and two groups of clamping plates 19 that are symmetrically arranged up and down are distributed in the receiving holes 15; one group of clamping plates 19 is connected with a telescopic support member, and the clamping plates 19 are driven by the telescopic support member to clamp the wires. Under the up and down telescopic movement of the telescopic support member, a clamping space is formed between the two clamping plates 19, so that the wires can be fixed between the two clamping plates.

[0108] For the telescopic support member, it specifically includes a receiving column 16, a stress column 18 and a second spring 17;

[0109] Among them, the stress column 18 is fixedly connected with the clamping plate 19, and the stress column 18 is slidably arranged in the receiving column 16 through a damping structure. The spring 17 is sleeved outside the receiving column 16 and the stress column 18 and is limited between the clamping plate 19 and the inner wall of the receiving hole 15. One end of the second spring 17 is fixedly connected with the clamping plate 19, and the other end is fixedly connected with the inner wall of the receiving hole 15. Thus, the movement of the stress column 18 in the receiving column 16 enables the clamping plate 19 to adjust its position according to the number of inserted wires, and maintains an appropriate pressure through the elastic force of the second spring 17 to ensure that the wires are safely fixed.

[0110] In summary, for the electric meter device with the anti-stealing electricity function disclosed in this embodiment, a plurality of receiving holes 15 are designed on the back side wall of the electric meter box body. As Figure 5 shown, clamping plates for clamping and fixing wires are distributed in the receiving holes 15. The clamping plates are integrally connected with the stress column 18. The stress column 18 is slidably connected to the inside of the receiving column 16, and the second spring 17 provides an elastic damping effect. The relevant structure settings in the receiving holes are designed specifically for fixing and managing the wires entering through the receiving holes 15. When the wires are inserted, the stress column 18 moves, pushing the clamping plate 19 to adjust its position according to the number of wires. The second spring 17 provides the necessary pressure to ensure that the wires are safely and stably fixed, prevent the wires from being wound around each other due to excessive amount, and reduce the maintenance difficulty and potential safety risks.

[0111] In addition, it should be specially noted that, as Figure 1 shown, a ventilation opening 11 for ventilation and heat dissipation is provided on one side wall of the electric meter box body 1; an observation window 10 for facilitating the observation of the internal situation of the electric meter box body 1 is provided on the surface of the box cover 7.

[0112] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
