[0033] The trigger starting mechanism 400 includes a gear 401. The bottom surface of the gear 401 is movably connected to the bottom surface of the inner shell 200 of the distribution box. A threaded post 402 is provided at the upper end of the gear 401. An active column 403 is threadedly connected to the threaded post 402. A side long block 404 is provided on one side of the active column 403. One end of the side long block 404 passing through the side slot 202 on the side of the inner shell 200 of the distribution box is provided with a trigger slot 409. A vertical frame 406 is provided on one side of the side long block 404. The upper end of the vertical frame 406 is movably connected to the upper end of the pressure receiving block 407. An induction chip 408 is provided on the surface of the pressure receiving block 407 that fits the vertical frame 406; the lower end of the pressure receiving block 407 is placed above the side long block 404; an extrusion side groove 405 is also provided on the side long block 404, and the extrusion side groove 405 is located directly below the pressure receiving block 407;

[0034] The diameter of the extrusion side groove 405 is larger than the thickness of the pressure receiving block 407;

[0035] Preferably, an inclined angle opening is provided at the lower end of the side of the pressure receiving block 407 that fits the vertical frame 406, which is convenient for the extrusion side groove 405 to lift the lower end of the pressure receiving block 407; the thickness of the lower end of the pressure receiving block 407 is greater than the thickness of the upper end, which is convenient for the pressure receiving block 407 to return to the state of fitting the vertical frame 406 without being squeezed by the extrusion side groove 405.

[0036] A rack 302 is provided at the lower end of the inner side surface of the door panel 300. A trigger insert block 301 is provided on the outer side surface of the door panel 300. When the side long block 404 is lifted to the highest position under the action of the active column 403, the height of the trigger slot 409 is level with the height of the trigger insert block 301; when the door panel 300 completes a 180-degree flip, the trigger insert block 301 and the trigger slot 409 are exactly docked;

[0037] Preferably, when the door panel 300 is in the closed state, the position height of the trigger insert block 301 is higher than the position of the trigger slot 409;

[0038] Preferably, during the flipping process of the door panel, the extrusion side groove 405 on the side long block 404 first squeezes the pressure receiving block 407. At this time, the induction chip 408 on the pressure receiving block 407 is separated from the corresponding induction chip 408 on the vertical frame 406. At this time, the electromagnet 507 is powered off, and at this time, the lock head 506 can be disengaged from the electromagnet 507; after the door panel 300 completes a 180-degree flip, at this time, the trigger slot 409 is lifted to the highest position, and the trigger insert block 301 and the trigger slot 409 are completed docking, and the drive motor 508 starts to drive the roller 505 to drive the folding grille 502 to gather towards both sides inside the ring frame 501; similarly, when the trigger insert block 301 is separated from the trigger slot 409, the drive motor 508 starts to drive the roller 505 to drive the folding grille 502 to expand towards the middle of the ring frame 501.

[0039] The internal protection mechanism 500 includes a ring frame 501. On both sides inside the ring frame 501, there are folding grilles 502. One end of the folding grille 502 is connected to the inner wall of the ring frame 501, and the other end is provided with a head 503. The lower end of the folding grille 502 is provided with a base 504. On the side of the base 504, there are rollers 505, and the rollers 505 are driven by a driving motor 508; on one side of the base 504, there is a lock head 506. The lower end of the head 503 can move along the bottom surface of the ring frame 501 through the rollers 505. One side of the folding grille 502 can be unfolded at most to the middle of the ring frame 501. At this time, the lock head 506 can be locked with the electromagnet 507 in the middle of the bottom surface of the ring frame 501.

[0040] On both sides at the lower end of the distribution box outer shell 100, there are movable grooves 101. The trigger slot 409 is placed in the movable groove 101, and the trigger slot 409 can move in the movable groove 101.

[0041] At the edge of the end of the distribution box inner shell 200, it is connected to the inner wall of the distribution box outer shell 100 through a connecting block 201. There is a certain gap between the distribution box outer shell 100 and the distribution box inner shell 200; the first movable plate 601 of the outer alarm trigger mechanism 600 is placed in the gap between the distribution box outer shell 100 and the distribution box inner shell 200. One side of the first movable plate 601 is connected to one end of a connecting rod 602. The other end of the connecting rod 602 passes through the outer wall of the distribution box inner shell 200 and is then connected to the second movable plate 604. A spring 603 is provided on the outside of the connecting rod 602 in the outer area of the distribution box inner shell 200. One end of the spring 603 is connected to the first movable plate 601, and the other end is connected to the outer wall of the distribution box inner shell 200.

[0042] When the rack 302 follows the door panel 300 to flip, the rack 302 meshes with the gear 401 to drive the gear 401 to rotate; the rack 302 is an arc-shaped rack.

[0043] On the side and back of the distribution box inner shell 200, there is an outer alarm trigger mechanism 600;

[0044] The outer alarm trigger mechanism 600 is divided into upper and lower parts. One end of the second movable plate 604 in each part of the outer alarm trigger mechanism 600 is provided with an alarm switch 605;

[0045] The alarm switch 605 in the upper half of the outer alarm trigger mechanism 600 is fixed to the top surface of the distribution box inner shell 200, and the alarm switch 605 in the lower half of the outer alarm trigger mechanism 600 is fixed to the bottom surface of the distribution box inner shell 200.

[0046] In actual situations, when the outer shell 100 of the distribution box is damaged by an external force, the external force breaks open the outer shell 100 of the distribution box, a part of the outer shell of the distribution box breaks inwards, and at the same time, the first movable plate 601 is squeezed, and finally the alarm switch 605 is turned on through the second movable plate 604, and each alarm switch 605 controls an alarm mechanism.

[0047] The side card slot 202 can limit the rotation of the side long block 404.

[0048] Preferably, both the electromagnet 507 and the drive motor 508 are controlled by a controller.

[0049] During use, in the state where the door panel 300 is closed, the folding grille 502 is in an unfolded state to protect the electrical appliances in the distribution box; when the door panel 300 is normally opened, the staff needs to flip the door panel 300 by 180 degrees. During the flipping process, the rack 302 drives the gear 401 to rotate, squeezes the side groove 405 to push up the pressure-receiving block 407 first, the electromagnet 507 unlocks the lock head 506, and finally triggers the docking of the insertion block 301 and the trigger slot 409, and the drive motor 508 drives the folding grille 502 to retract;

[0050] When the distribution box is maliciously damaged, if the outer shell 100 of the distribution box is damaged, the alarm mechanism will be triggered by the outer alarm triggering mechanism 600. If the door panel 300 is maliciously removed, the trigger starting mechanism 400 will not be triggered, and thus the internal protection mechanism 500 will not be unlocked, and the electrical components of the distribution box will be protected by the internal protection mechanism 500.

[0051] In summary, an outer alarm triggering mechanism 600 is provided around the distribution box. When the distribution box is maliciously damaged, the external force triggers the movement of the second movable plate 604, and then the alarm switch 605 is turned on to trigger the alarm mechanism; when the distribution box is not opened, the internal protection mechanism 500 will protect the electrical appliances in the distribution box; when the door panel is normally opened without being flipped 180 degrees, the trigger insertion block 301 cannot be paired with the trigger slot 409, and the internal protection mechanism 500 will not be opened, protecting the electrical components in the distribution box.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limitations. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
