[0025] See also Figures 1 to 4 The present invention provides a structure suitable for the anti-theft function of an electric energy meter, comprising: a housing 1, an electric energy meter 10 is installed in the housing 1, the electric energy meter 10 includes a function display area 101 and a power connection area 102, and a window 11 for observing the function display area 101 and the power connection area 102 is opened on the housing 1; a sliding cover assembly 2, the sliding cover assembly 2 is slidably inserted inside the window 11 to move and close the window 11 to protect the function display area 101 and the power connection area 102; an anti-theft cover assembly 3, an anti-theft cover assembly 3, The cover assembly 3 is slidably inserted inside the window 11 to move and close the power connection area 102 to protect the power connection area 102; the transmission assembly 4, the sliding cover assembly 2 is transmission-connected to the anti-theft cover assembly 3 through the transmission assembly 4, so that when the sliding cover assembly 2 continues to move before opening the window 11, the anti-theft cover assembly 3 is transmitted to the top of the power connection area 102 for protection, and when the sliding cover assembly 2 continues to move after completing the closing of the window 11, the anti-theft cover assembly 3 is transmitted away from the top of the power connection area 102.

[0026] From the above, it is not difficult to find that in the anti-electricity theft functional structure of the present invention, the electric energy meter 10 can be installed in the housing 1, and the housing 1 is installed at a set installation position to prevent electric energy theft. Specifically, a sliding cover assembly 2 is provided on the window 11 of the housing 1. The sliding cover assembly 2 can achieve full closure and opening of the window 11. When opened, the functional display area 101 of the electric energy meter 10 can be opened accordingly. In order to prevent the power connection area 102 from being opened, so that the power thief can use the power connection area 102 to modify and steal electricity, before the sliding cover assembly 2 is opened, and during the movement of the sliding cover assembly 2, the transmission assembly 4 will correspondingly drive the anti-theft cover assembly 3 to arrive at the corresponding upper part of the power connection area 102 in advance, so that when the sliding cover assembly 2 continues to move to open the window 11, the anti-theft cover assembly 3 has already reached the power connection area 102, and the wiring of the power connection area 102 is protected. After opening window 11, the user can operate the function display area 101 of the energy meter 10, for example, by using function display area 101 to charge or pay the electricity card, or by using the query button to query the power consumption. Furthermore, after use, the sliding cover assembly 2 can be pulled down to further seal window 11, achieving dust and water resistance. Furthermore, after the sliding cover assembly 2 completely seals window 11, the anti-theft cover assembly 3 is unlocked and, driven by the transmission assembly 4, moves away from the power connection area 102, allowing the user to observe not only the status of the function display area 101 but also the power connection status of the power connection area 102 through the sliding cover assembly 2.

[0027] like Figure 2 As shown, one side of the bottom of the housing 1 corresponds to the wiring side of the power connection area 102 . A plurality of wire holes 12 are provided on the bottom of the housing 1 , and the wire holes 12 are away from the power connection area 102 .

[0028] In this embodiment, it can be seen that when connecting the power connection area 102 of the energy meter 10, the live and neutral wires of the external power supply and the live and neutral wires of the household can be installed on the power connection area 102 by passing through the wire hole 12 on the bottom side of the housing 1. After installation, because the bottom side of the housing 1 is far away from the power connection area 102, electricity thieves cannot access the power connection area 102, thereby effectively solving the problem of electricity thieves stealing electricity by directly using the power connection area 102.

[0029] like Figure 3 and Figure 4 As shown, the sliding cover assembly 2 includes: a sliding cover 21, a protective window 211 is provided on the sliding cover 21, the protective window 211 is a transparent window, and a push block 212 is installed on the outer surface of the sliding cover 21; and a first support frame 22, the upper end of the first support frame 22 is connected to the sliding cover 21, the lower end of the first support frame 22 is slidably installed in the shell 1, and the lower end of the first support frame 22 is connected to the transmission assembly 4; wherein, the length of the sliding cover 21 is greater than the length of the window 11.

[0030] In the present embodiment, in the specific structure of the sliding cover assembly 2, the user can increase the friction when contacting the sliding cover 21 by holding the push block 212, so that the sliding cover 21 can be easily opened or closed. And when the sliding cover 21 is closed, the user can observe the function display area 101 and the power connection area 102 of the electric energy meter 10 through the protective window 211. The protective window 211 can be made of tempered glass, laminated glass, etc., so as to improve the rigidity of the protective window 211 while ensuring the transparency of the protective window 211. When the sliding cover 21 slides, the first support frame 22 at its bottom can transmit the transmission assembly 4, further driving the anti-theft cover assembly 3 to move back and forth. The length of the sliding cover 21 is set to be greater than the length of the window 11, so that the transmission assembly 4 can be transmitted while the sliding cover 21 is still in a closed state with respect to the window 11, driving the anti-theft cover assembly 3 to isolate the power connection area 102. Similarly, after the sliding cover 21 closes the viewing window 11 , the sliding cover 21 continues to move, driving the anti-theft cover assembly 3 away from the power connection area 102 , so that the corresponding status of the power connection area 102 can be viewed through the protective window 211 .

[0031] Furthermore, the anti-theft cover assembly 3 includes: an anti-theft cover 31, a shock-absorbing pad 311 is installed on one side of the anti-theft cover 31 along the vertical direction of its movement; and a second support frame 32, the upper end of the second support frame 32 is connected to the anti-theft cover 31, the lower end of the second support frame 32 is slidably installed in the shell 1, and the lower end of the second support frame 32 is connected to the transmission assembly 4.

[0032] In this embodiment, when the sliding cover assembly 2 moves, it drives the transmission assembly 4, which in turn drives the second support frame 32 to move, thereby isolating or releasing the anti-theft cover 31 from the power area 102. When the anti-theft cover 31 is isolated from the power area 102, the end side of the anti-theft cover 31 can be pressed against the side of the energy meter 10 via the shock-absorbing pad 311 to reduce the impact of the anti-theft cover 31 on the energy meter 10.

[0033] like Figures 4 to 6As shown, the transmission assembly 4 includes: a slide 41, the slide 41 is connected to the anti-theft cover assembly 3, the top of the slide 41 is provided with a hanging groove 411, and the bottom of the slide 41 is provided with a locking groove 412; a locking assembly 42, the locking assembly 42 is arranged below the slide 41, and the locking assembly 42 is elastically connected to the housing 1; and a moving traction assembly 43, the moving traction assembly 43 is connected to the slide assembly 2, and the moving traction assembly 43 is transmission-connected to the locking assembly 42; wherein, when the slide assembly 2 is pulled toward the side of the window 11, the moving traction assembly 43 is hung in the hanging groove 411 to The anti-theft cover assembly 3 connected to the sliding seat 41 is pulled to the top of the power connection area 102 for protection. After the anti-theft cover assembly 3 reaches the power connection area 102, the locking assembly 42 is locked in the locking groove 412. At the same time, the mobile pulling assembly 43 leaves the hanging groove 411 and continues to move to open the window 11. When the sliding cover assembly 2 completes closing the window 11 and continues to be pulled in the closing direction, the mobile pulling assembly 43 is hung in the hanging groove 411, and the locking assembly 42 leaves the locking groove 412, so as to pull the anti-theft cover assembly 3 connected to the sliding seat 41 away from the top of the power connection area 102 and be protected by the sliding cover assembly 2.

[0034] In this embodiment, when the transmission assembly 4 is transmitting the power of the slide assembly 2 to the anti-theft cover assembly 3, before the slide assembly 2 opens the window 11, the slide 41 pushes the locking assembly 42 away from the locking groove 412 at the bottom of the slide 41. At the same time, the mobile traction assembly 43 connected to the slide assembly 2 is hung in the hanging groove 411, carrying the slide 41 and the anti-theft cover assembly 3 connected to the slide 41 together, so that the anti-theft cover assembly 3 reaches the top of the power connection area 102. After the anti-theft cover assembly 3 is in place, the mobile traction assembly 43 leaves the hanging groove 411, and the locking assembly 42 locks into the locking groove 412, thereby achieving the stability and anti-theft performance of the anti-theft cover assembly 3. The mobile traction assembly 43 then leaves the hanging groove 411 and continues to move with the slide assembly 2 to open the window. Similarly, when the slide assembly 2 returns to close the window 11, the mobile traction assembly 43 is first in a state of leaving the hanging groove 411. After the viewing window 11 is closed, when the sliding cover assembly 2 continues to move, the movable traction assembly 43 will continue to be hung in the hanging groove 411, and then the locking assembly 42 will leave the locking groove 412, so that the sliding cover assembly 2 and the anti-theft cover assembly 3 can be moved away together, so that the status of the energy meter 10 can be observed through the closed sliding cover assembly 2. In this way, the physical lock can be omitted and the energy meter 10 can be directly protected from electricity theft.

[0035] like Figures 4 to 6As shown, the locking assembly 42 includes: a lifting bracket 421; a first spring 422, one end of the first spring 422 is connected to the lifting bracket 421, and the other end of the first spring 422 is connected to the inner wall of the shell 1; a locking head 423, one end of the locking head 423 is installed on the lifting bracket 421, and the other end of the locking head 423 is arranged corresponding to the locking groove 412; and a guide head 424, one end of the guide head 424 is installed on the lifting bracket 421, and the other end of the guide head 424 is movably inserted into the bottom of the movable traction assembly 43, so that the locking head 423 can be inserted into or leave the locking groove 412 when the movable traction assembly 43 moves.

[0036] In this embodiment, when the locking head 423 needs to leave the locking groove 412 during the movement of the movable pulling assembly 43, the movable pulling assembly 43 will push the guide head 424 downward to move downward, and the locking head 423 on the lifting bracket 421 will also move downward, thereby leaving the locking groove 412, thereby unlocking the slide 41, thereby enabling the anti-theft cover assembly 3 to move back and forth. When the slide assembly 2 drives the anti-theft cover assembly 3 to reach above the power connection area 102, the movable pulling assembly 43 will no longer exert pressure on the guide head 424. Therefore, under the elastic force of the lifting bracket 421 and the locking head 423, the locking head 423 is inserted into the locking groove 412, thereby locking the slide 41 and the anti-theft cover assembly 3 in position.

[0037] like Figures 5 to 8 As shown, the movable traction assembly 43 includes: a first guide bracket 431, one end of the first guide bracket 431 is connected to the sliding cover assembly 2, and a first guide rail 4311 is provided at the bottom of the first guide bracket 431 to guide the locking assembly 42 to move up and down; a guide frame 432, the guide frame 432 is installed on the first guide bracket 431; a guide joint 433, the guide joint 433 is installed on the guide frame 432, and one end of the guide joint 433 is arranged corresponding to the hanging groove 411; and a guide seat 434, the guide seat 434 is installed on the shell 1, and a second guide rail 4341 is provided on one side of the guide seat 434, and the other end of the guide joint 433 is slidably arranged in the second guide rail 4341 to guide the guide joint 433 to move up and down.

[0038] The first guide rail 4311 can include a first upper rail 43112 and a first lower rail 43111. There is a height difference between the first upper rail 43112 and the first lower rail 43111, and the first upper rail 43112 and the first lower rail 43111 are smoothly connected via a diagonally arranged first intermediate rail. During operation of the moving and pulling assembly 43, the first guide bracket 431 is driven back and forth by the sliding cover assembly 2. When the sliding cover assembly 2 moves before opening the window 11, the guide head 424 of the locking assembly 42 is within the first upper rail 43112. At this time, the guide head 424 moves upward relative to the first lower rail 43111, causing the locking head 423 to lock into the locking groove 412. When the guide head 424 of the locking assembly 42 is within the first lower rail 43111, it moves downward relative to the first upper rail 43112, causing the locking head 423 to exit the locking groove 412.

[0039] The second guide rail 4341 may include a second upper rail 43412 and a second lower rail 43411. There is a height difference between the second upper rail 43412 and the second lower rail 43411, and the second upper rail 43412 and the second lower rail 43411 are smoothly connected via a diagonally arranged second intermediate rail. When the sliding cover assembly 2 moves before opening the window 11, the guide connector 433 is inserted into the hanging slot 411 within the guide frame 432 and guided by the second lower rail 43411 of the guide seat 434, thereby pulling the anti-theft cover assembly 3 toward the power supply area 102. As the sliding cover assembly 2 continues to open the window 11, it passes through the second intermediate rail and enters the second upper rail 43412. At this point, the guide connector 433 exits the hanging slot 411, restrained by the second guide rail 4341.

[0040] like Figure 7 As shown, the guide frame 432 includes: an installation frame 4321, which is installed on the first guide bracket 431; a lifting block 4322, which is vertically slidably installed in the installation frame 4321; a connecting rod 4323, each end of the connecting rod 4323 is connected to a lifting block 4322, and the guide joint 433 is slidably inserted on the connecting rod 4323; a second spring 4324, which is sleeved on the connecting rod 4323, one end of the second spring 4324 is connected to the lifting block 4322, and the other end of the second spring 4324 is connected to the guide joint 433; and a lifting guide rod 4325, which is vertically slidably installed in the installation frame 4321, and the guide joint 433 is inserted into the lifting guide rod 4325.

[0041] When the guide frame 432 positions the guide joint 433, the connecting rod 4323 is used to limit the guide joint 433 along the length of the first guide bracket 431. Furthermore, the second spring 4324 allows the guide joint 433 to move upward from the hanging groove 411 during the movement of the first guide bracket 431, as the guide joint 433 moves along the second middle rail to the second upper rail 43412 or the second lower rail 43411. During this time, the second spring 4324 stores energy, and when the guide joint 433 completely leaves the hanging groove 411, the guide joint 433 is back in the middle position of the connecting rod 4323. The lifting guide rod 4325 guides the guide joint 433 as it moves up and down, and the lifting block 4322 guides the connecting rod 4323. Specifically, a sliding seat is also provided at the upper and lower ends of the lifting guide rod 4325, and the sliding seat is slidably connected to the mounting frame 4321, so that the lifting guide rod 4325 can move back and forth along the length direction of the first guide bracket 431 following the guide joint 433.

[0042] like Figure 4 As shown, the transmission assembly 4 also includes: an unlocking assembly 44, which is installed on the housing 1, and the power output end of the unlocking assembly 44 is connected to the locking assembly 42; and a controller, which is used to receive maintenance control instructions and pull the locking assembly 42 out of the locking groove 412 through the unlocking assembly 44.

[0043] In this embodiment, maintenance personnel can connect to the network through identity verification or other means. Then, when the controller receives a maintenance control command after successful verification, the unlocking assembly 44 will actively pull the locking assembly 42 downward out of the locking slot 412, thereby unlocking the anti-theft cover assembly 3. Furthermore, after the maintenance is completed, the unlocking assembly 44 will automatically move away from the locking assembly 42 to prevent interference with the normal transmission of the sliding cover assembly 2 and the anti-theft cover assembly 3.

[0044] like Figure 5 As shown, the unlocking assembly 44 includes: a driving member 441, which is installed on the shell 1; an insertion rod 442, the first end of which is connected to the power output end of the driving member 441, and the other end of which passes through the lifting bracket 421; and a limiting plate 443, the second end of which is connected to the limiting plate 443.

[0045] The driving member 441 can be a push rod motor or other linear power mechanism. After receiving the maintenance control command, the controller controls the driving member 441 to pull the insertion rod 442 and the limit plate 443 to move together, thereby driving the lifting bracket 421 to move downward, so that the locking assembly 42 leaves the locking slot 412.

[0046] See also Figure 9 In order to meet the needs of more users, multiple shells 1 can be spliced ​​together, and then the electric energy meter 10 can be installed in each shell 1 respectively, so as to achieve separate protection for all the electric energy meters 10 installed in each shell 1.

[0047] In summary, the structure disclosed in the present invention is suitable for the anti-theft function of an electric energy meter. By utilizing the linkage between the transmission assembly 4 and the anti-theft cover assembly 3 through the sliding cover assembly 2, the power connection area 102 of the electric energy meter 10 can be protected without affecting the user's normal operation of the observation function display area 101 of the electric energy meter 10. This solves the problem that when the traditional electric energy meter box is in an open state, the thief can directly operate the power connection area 102 of the electric energy meter 10 to perform illegal acts such as modifying or stealing electricity. It also achieves the anti-theft function of the electric energy meter 10 without locking the electric energy meter box. Moreover, by utilizing the unlocking assembly 44, it is convenient for maintenance personnel to directly unlock the anti-theft cover assembly 3 according to the maintenance control signal during maintenance, thereby facilitating the maintenance personnel's inspection work. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has high industrial utilization value.
