Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0037] In addition, the components in the present utility model are referred to as "fixed to" or "disposed on" another component. It can be directly on another component or there can be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0038] Please refer to Figures 1 - 8 , in an embodiment of the present utility model, a multi-dimensional warning switch cabinet integrating system alarm and buzzer includes a cabinet body 1 and a cabinet door 3 rotatably connected to the cabinet body 1 through a hinge 2. A lock core 4 is rotatably installed on the cabinet door 3, and an L-shaped rod 5 is provided at one end of the lock core 4;

[0039] A base 6 is provided on the cabinet body 1. A first switch 7 and a second switch 8 are vertically symmetrically provided on the base 6. A warning component is provided on the cabinet body 1, and the first switch 7 and the second switch 8 are respectively connected to the warning component;

[0040] A trigger component cooperating with the L-shaped rod 5 is provided on the base 6. The first switch 7 and the second switch 8 are respectively connected to the trigger component through two sets of transmission structures. The trigger component will, under the interaction of the L-shaped rod 5, cause the first switch 7 and the second switch 8 to be turned on through the two sets of transmission structures, so as to cause the warning component to operate.

[0041] In this solution, when the cabinet door 3 is violently pulled, the L-shaped rod 5 will cooperate with the trigger component under the drive of the cabinet door 3 and the lock core 4, so that the two sets of transmission structures will respectively turn on the first switch 7 and the second switch 8 under the action of the trigger component, thereby causing the warning component to operate. On the one hand, the warning component can notify relevant maintenance personnel, and on the other hand, it can play a deterrent role against lawbreakers.

[0042] As a further solution of the present utility model, the trigger component includes a slider 9 slidably matched with the base 6 horizontally. One end of the slider 9 is in contact with the L-shaped rod 5;

[0043] Limit posts 10 are provided on both sides of the slider 9. A limit groove 11 is horizontally opened on the base 6, and the limit posts 10 are slidably matched with the limit groove 11.

[0044] In this embodiment, since the slider 9 is in contact with the L-shaped rod 5, when an illegal person violently pulls the cabinet door 3, the cabinet door 3 will drive the L-shaped rod 5 through the lock core 4 to push the slider 9, so that the slider 9 slides in cooperation with the base 6 in the direction of the cabinet door 3. During this process, the limit post 10 will also slide in cooperation with the limit groove 11 under the drive of the slider 9.

[0045] As a further solution of the present utility model, the trigger assembly further includes a slide rod 12 that is horizontally slidably matched with the base 6, and a circular plate 13 connected to one end of the slide rod 12. The circular plate 13 is located inside the base 6 and is in contact with the inner wall of the base 6 away from the slider 9.

[0046] A spring 14 is arranged inside the base 6, and both ends of the spring 14 are respectively abutted against the circular plate 13 and the slider 9.

[0047] In this embodiment, due to the existence of the spring 14 and it being in a compressed state, and both ends of the spring 14 are respectively abutted against the circular plate 13 and the slider 9, the slider 9 needs to overcome the elastic force of the spring 14 during the movement process, so as to compress the spring 14. Also, because the circular plate 13 is located inside the base 6 and is in contact with the inner wall of the base 6 away from the slider 9, the base 6 will support the circular plate 13.

[0048] As a further solution of the present utility model, the transmission structure includes two vertical rods 15 respectively connected to the first switch 7 and the second switch 8. A roller 16 is rotatably arranged at the end of the vertical rod 15.

[0049] An L-shaped plate 17 is arranged on the slider 9. The roller 16 abuts against the L-shaped plate 17. A chute 18 is formed on the base 6, and the L-shaped plate 17 is slidably matched with the chute 18.

[0050] In this embodiment, since the L-shaped plate 17 is arranged on the slider 9 and the roller 16 rotatably arranged on the vertical rod 15 abuts against the L-shaped plate 17, during the movement of the slider 9, the roller 16 will perform relative rolling cooperation with the slider 9. At the same time, the L-shaped plate 17 will also perform sliding cooperation with the chute 18.

[0051] As a further solution of the present utility model, a trapezoidal block 1701 is arranged on the L-shaped plate 17, and the inclined surface of the trapezoidal block 1701 corresponds to the roller 16.

[0052] The outer wall of the vertical rod 15 and the other end of the slide rod 12 are rotatably connected by a connecting rod 19.

[0053] In this embodiment, since the trapezoidal block 1701 is provided on the L-shaped plate 17 and the inclined surface of the trapezoidal block 1701 corresponds to the roller 16, when the roller 16 contacts the trapezoidal block 1701, the roller 16 will drive the vertical rod 15 to move vertically, thereby activating the first switch 7 and the second switch 8 respectively;

[0054] Since the sliding rod 12 is connected to the circular plate 13 and the outer wall of the vertical rod 15 is rotationally connected to the other end of the sliding rod 12 through the connecting rod 19, during the vertical movement of the vertical rod 15, the sliding rod 12 will move towards the spring 14 under the drive of the connecting rod 19, thereby driving the circular plate 13 to move towards the spring 14, and further compressing the spring 14, so that the slider 9 needs to overcome greater resistance when moving;

[0055] Through the mutual cooperation between the trigger assembly and the transmission structure, the compression of the spring 14 in the initial state does not have to be too large. Only when the cabinet door 3 is violently pulled, the spring 14 will be further compressed, thus avoiding the spring 14 being in an over-pressured state for a long time, resulting in mechanical fatigue of the spring 14, and thus prolonging its service life.

[0056] As a further solution of the present invention, the warning assembly includes a three-color buzzer alarm 20 provided on the top of the cabinet body 1 and a PLC controller 21 installed inside the cabinet body 1;

[0057] The three-color buzzer alarm 20 is electrically connected to the first switch 7, and the PLC controller 21 is electrically connected to the second switch 8. Among them, the three-color buzzer alarm 20 and the PLC controller 21 can adopt existing technologies.

[0058] In this embodiment, since the three-color buzzer alarm 20 is electrically connected to the first switch 7, when the first switch 7 is turned on, the three-color buzzer alarm 20 will start and emit a flash and a buzzer sound, thus playing a deterrent role against illegal personnel;

[0059] Also, because the PLC controller 21 is electrically connected to the second switch 8, when the second switch 8 is turned on, the PLC controller 21 will operate and send an electrical signal to the maintenance personnel to remind people that the switch cabinet is being damaged.

[0060] As a further solution of the present invention, a handle 301 is provided on the cabinet door 3, a limiting rod 22 is horizontally provided on the base 6, and the L-shaped rod 5 abuts against the top surface of the limiting rod 22.

[0061] In this embodiment, the provided handle 301 facilitates the opening and closing of the cabinet door 3; the limiting rod 22 is used to support and limit the L-shaped rod 5, so that the L-shaped rod 5 can be accurately attached to the slider 9; when normally opening, insert the key into the lock core 4 and drive the lock core 4 to rotate 90 degrees, so that the L-shaped rod 5 is separated from the slider 9, and then the cabinet door 3 can be normally opened.
