[0013] 1. In the utility model, by setting a limit device, when the alarm body needs to be repaired, first slide the T-plate to make the T-plate move inside the slide groove. The movement of the T-plate inside the slide groove will squeeze the spring, so that the spring is compressed. At the same time, the movement of the T-plate inside the slide groove also drives the insertion rod to move. The movement of the insertion rod causes it to move out of the inside of the socket. The separation of the insertion rod and the socket causes the L-shaped limit plate to lose its limit inside the limit frame. At this time, the L-shaped limit plate can be pulled downward to make the L-shaped limit plate detach from the inside of the limit frame, thereby completing the disassembly operation of the alarm body. Through the cooperation of the above-mentioned structure, the purpose of disassembling the alarm body is achieved, the operation is simple, and various disadvantages brought about by the installation method using screws and threads are avoided.

A slide plate 42 is slidably connected inside the vertical groove 41, and a limit frame 43 is fixedly installed on the surface of one end of the slide plate 42 away from the vertical groove 41.

[0027] In this embodiment, the provision of the L-shaped limiting plate 3 and the limiting frame 43 plays a role in preliminarily installing the alarm body 2 and the mounting bracket 1 .

[0028] Specifically, both side surfaces of the limit frame 43 are provided with slide grooves 44, a T-shaped plate 45 is slidably connected between the two slide grooves 44, an insertion rod 46 is fixedly installed on the surface of the T-shaped plate 45, and a plug hole 47 is provided on the surface of the vertical end of the L-shaped limit plate 3.

[0029] In this embodiment, the arrangement of the insert rod 46 and the insert hole 47 has the effect of limiting the L-shaped limiting plate 3 inside the limiting frame 43 .

[0030] Specifically, a spring 48 is fixedly mounted on the surface of one end of the T-shaped plate 45 away from the insertion rod 46, and the end of the spring 48 away from the T-shaped plate 45 is fixedly connected to the inner wall of one side of the limit frame 43. The setting of the spring 48 has the effect of limiting the position of the T-shaped plate 45 inside the slide groove 44.

[0031] In this embodiment: a support device 5 is provided on the surface of the mounting frame 1, and the support device 5 includes a hollow plate 501, the hollow plate 501 is fixedly mounted on the surface of the mounting frame 1, an extension plate 502 is slidably connected inside the hollow plate 501, and a support plate 503 is fixedly mounted on the surface of the end of the extension plate 502 away from the hollow plate 501. When the L-shaped limiting plate 3 needs to be supported, the hand wheel 506 is first rotated, and the rotation of the hand wheel 506 drives the threaded rod 505 to rotate, and the rotation of the threaded rod 505 drives the moving plate 508 to move inside the groove 507, and the moving plate 508 moves inside the groove 507 to drive the limiting rod 509 to move, and the limiting rod 509 moves to move itself out of the limiting hole 510, and the limiting rod 509 and the limiting hole 510 are separated to make the extension plate 502 lose its limit inside the hollow plate 501, and then the extension plate 502 can be moved. The extension plate 502 moves, driving the support plate 503 to move. When the support plate 503 moves to the bottom of the L-shaped limit plate 3, the hand wheel 506 is reversed to reinsert the limit rod 509 into the corresponding limit hole 510 to fix the position of the extension plate 502 at this time. Through the cooperation of the above structure, the support plate 503 can support the L-shaped limit plate 3, thereby providing convenience for the staff when using the limit device 4 to install between the alarm body 2 and the mounting frame 1.

[0032] Specifically, a U-shaped plate 504 is fixedly installed on the side of the hollow plate 501 , a threaded rod 505 is rotatably connected between the inner walls at both ends of the U-shaped plate 504 , and a hand wheel 506 is fixedly installed at one end of the threaded rod 505 .

[0033] In this embodiment, the setting of the hand wheel 506 plays the effect of driving the threaded rod 505 to rotate.

[0034] Specifically, a groove 507 is formed on the inner wall surface of the U-shaped plate 504 , a movable plate 508 is threadedly connected to the surface of the threaded rod 505 , a limiting rod 509 is fixedly installed on the surface of the movable plate 508 , and a plurality of limiting holes 510 are evenly formed on the side surface of the extension plate 502 .

[0035] In this embodiment, the setting of the limiting rod 509 and the limiting hole 510 has the effect of limiting the position of the extension plate 502 .

[0036] Working principle: by setting the limit device 4, when the alarm body 2 needs to be repaired, first slide the T-plate 45 to make the T-plate 45 move inside the slide groove 44. The movement of the T-plate 45 inside the slide groove 44 will squeeze the spring 48, so that the spring 48 is compressed. At the same time, the movement of the T-plate 45 inside the slide groove 44 also drives the insertion rod 46 to move. The movement of the insertion rod 46 makes it move out from the inside of the socket 47. The insertion rod 46 and the socket 47 separate to make the L-shaped limit plate 3 lose its limit inside the limit frame 43. At this time, the L-shaped limit plate 3 can be pulled downward to make the L-shaped limit plate 3 detach from the inside of the limit frame 43, thereby completing the disassembly operation of the alarm body 2. Through the cooperation of the above-mentioned structure, the purpose of disassembling the alarm body 2 is achieved, the operation is simple, and the various disadvantages brought about by the installation method using screws and threads are avoided. When the L-shaped limit plate 3 needs to be supported, the hand wheel 506 is first turned. The rotation of the hand wheel 506 drives the threaded rod 505 to rotate. The rotation of the threaded rod 505 drives the movable plate 508 to move inside the groove 507. The movable plate 508 moves inside the groove 507 and drives the limit rod 509 to move. The limit rod 509 moves to move itself out of the limit hole 510. The limit rod 509 and the limit hole 510 are separated, so that the extension plate 502 loses its limit in the hollow plate 501. At this time, the extension plate 502 can be moved. The extension plate 502 moves, driving the support plate 503 to move. When the support plate 503 moves to the bottom of the L-shaped limit plate 3, the hand wheel 506 is reversed to reinsert the limit rod 509 into the corresponding limit hole 510 to fix the position of the extension plate 502 at this time. Through the cooperation of the above structure, the support plate 503 can support the L-shaped limit plate 3, thereby providing convenience for the staff when using the limit device 4 to install between the alarm body 2 and the mounting frame 1.
