[0031] As shown in Figures 1-8 , theft-proof brake assembly 4 further includes pulling pin 408, pulling rod 409, front and rear slide rails 411, pulling pin 408 is fixed on ratchet bar 407, front and rear slide rails 411 are fixed on the inner wall of lateral extension theft-proof cover 101, pulling rod 409 is slidably arranged on front and rear slide rails 411, pulling groove 410 is vertically arranged on pulling rod 409, pulling pin 408 is engaged in pulling groove 410.

[0032] As shown in Figures 1-8 , lateral extension theft-proof cover 101 is detachably provided with side sealing plate 5, two limit clamping plates 501 are fixed on side sealing plate 5, pulling rod 409 is engaged between the two limit clamping plates 501.

[0033] As shown in Figures 1-8As shown, the bottom of the lateral extension anti-theft cover 101 is fixedly provided with an extension bottom plate 103, the lower guide rod 3 is slidably connected with the extension bottom plate 103, the bottom end of the inner slide rod 401 is fixedly arranged above the extension bottom plate 103, and the anti-theft brake assembly 4 further comprises a press-type alarm 412, which is fixedly arranged above the extension bottom plate 103 and located below the height-limiting plate 405.

[0034] As shown in Figures 1-8 , the bottom of the height-limiting plate 405 is provided with a thinning groove 406.

[0035] As shown in Figures 1-8 , the top end of the lower guide rod 3 is fixedly provided with a connecting magnetic sheet 413, and the connecting magnetic sheet 413 has a magnetic attraction force with the brake seat 402.

[0036] As shown in Figures 1-8 , the connection between the lateral extension anti-theft cover 101 and the lower slide cover 2 is provided with a lower lead seal lock 6, and the connection between the lateral extension anti-theft cover 101 and the side seal plate 5 is provided with an upper lead seal cap 502.

[0037] As shown in Figures 1-8 , the side surface of the lower slide cover 2 is provided with a wire outlet 201.

[0038] Embodiment one, this embodiment is used to describe the running state of the anti-theft brake assembly 4 when the lower slide cover 2 is correctly removed to adjust the lower wiring condition of the electric energy meter main body 1.

[0039] Before removing the lower slide cover 2 and the lower lead seal lock 6, the electrician first removes the upper lead seal cap 502, and exposes the connection between the side seal plate 5 and the lateral extension anti-theft cover 101. Then, the side seal plate 5 is removed from the lateral extension anti-theft cover 101, and the front and rear limiting of the pulling rod 409 by the limiting clamping plate 501 is released. After the side seal plate 5 on the lateral extension anti-theft cover 101 is removed and the pulling rod 409 is exposed, the electrician pushes the pulling rod 409 backward, so that the pulling rod 409 moves backward along the front and rear slide rails 411. During this process, the vertically arranged pulling groove 410 on the pulling rod 409 drives the pulling pin 408 to move backward synchronously with the ratchet bar 407, and the contact relationship between the ratchet bar 407 and the brake ratchet pawl 403 is disconnected.

[0040] After the electrician removes the lower lead seal lock 6, the lower slide cover 2 is pulled downward. At this time, the connecting magnetic sheet 413 at the top end of the lower guide rod 3 drives the brake seat 402 to move downward synchronously with the brake ratchet pawl 403 through the magnetic attraction force. Since the ratchet bar 407 has been moved backward in advance, the downward movement of the brake ratchet pawl 403 will not be hindered. During the process of being pulled downward by the electrician, the brake ratchet pawl 403 will finally be hindered by the extension bottom plate 103, and the magnetic attraction connection of the connecting magnetic sheet 413 to the brake seat 402 will be overcome.

[0041] Finally, the electrician will only pull out the lower sliding cover 2 and the lower guide rod 3, and the anti-theft brake assembly 4 including the brake seat 402, the brake pawl 403 and other components will not be observed, thereby maintaining good concealment and being difficult to be cracked and electricity stolen subsequently.

[0042] In the second embodiment, the working principle of the anti-theft brake assembly 4 is described.

[0043] Since the upper lead seal cap 502 is not in direct contact with the lower sliding cover 2, the electricity thief is difficult to think of removing the opposite side sealing plate 5 and the upper lead seal cap 502 when trying to break the lower lead seal lock 6 and open the lower sliding cover 2.

[0044] When the electricity thief breaks the lower lead seal lock 6 and pulls down the lower sliding cover 2, the downward pulling force of the lower guide rod 3 and the lower sliding cover 2 is transmitted to the brake seat 402 and the brake pawl 403 on the brake seat 402 through the connecting magnetic sheet 413. Under the constraint of the tooth profile of the brake pawl 403 and the ratchet bar 407, the brake pawl 403 connected between the brake seat 402 and the ratchet bar 407 by the compression spring 404 cannot directly move downward, and the downward force is transmitted to the ratchet bar 407, so that the height limiting plate 405 below the ratchet bar 407 can be easily broken due to the pre-set thinning groove 406, and no longer blocks the ratchet bar 407. Then the ratchet bar 407 and the broken pieces of the height limiting plate 405 trigger the press alarm 412.

[0045] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
