[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 As shown, a mounting base includes a support plate 1 with a mounting groove 2 inside. An alarm device body 3 is mounted on one side of the support plate 1, and the alarm device body 3 can be inserted into the mounting groove 2. A positioning mechanism 4 is provided inside the mounting groove 2, which limits the position of the alarm device body 3 and prevents it from easily detaching from the mounting groove 2. A fixing frame 6 is provided at the bottom of the support plate 1, and a protective cover 7 is bolted to the top of the fixing frame 6. The bottom of the support plate 1 is rotatably connected to the top of the protective cover 7. A transmission disc 8 is rotatably connected to one side of the top of the fixing frame 6. The other side of the transmission disc 8... The end is bolted to the bottom of the support plate 1. When it is necessary to adjust the direction of the horn of the main body 3 of the alarm device, rotating the support plate 1 can rotate the transmission plate 8, which can also drive the main body 3 of the alarm device to rotate. The protective cover 7 is equipped with a limit mechanism 9. The limit mechanism 9 works in conjunction with the transmission plate 8. Under the action of the limit mechanism 9, the transmission plate 8 can be limited. Under this action, the main body 3 of the alarm device can be prevented from rotating easily. A slide groove 10 is opened on one side of the top of the fixed frame 6. A slider 11 is slidably connected to the inner wall of the slide groove 10. The limit mechanism 9 works in conjunction with the slider 11. Under the action of the slider 11, the internal parts of the limit mechanism 9 can run more stably.

[0023] The positioning mechanism 4 includes two positioning plates 41. One side of the surface of each positioning plate 41 is slidably connected to one side of the inner wall of the mounting groove 2. Two first compression springs 42 are fixedly connected to the surface of each positioning plate 41, evenly distributed on both sides of the surface. The other end of each first compression spring 42 is fixedly connected to one side of the inner wall of the mounting groove 2. A pull ring 43 is bolted to one side of the surface of one positioning plate 41. When the pull ring 43 moves, the positioning plate 41 on that side can move. A rack plate 44 is bolted to one side of the surface of each positioning plate 41. One side of the rack plate 44 is slidably connected to one side of the inner wall of the mounting groove 2. When one positioning plate 41 moves, the rack plate 44 on that side can move. One side of the rack plate 44 has a T-shaped design and is connected to the mounting groove. 2. One side of the inner wall is T-shaped, which makes the movement of the rack plate 44 more stable. The opposite sides of the rack plates 44 are meshed with a spur gear 45. When one rack plate 44 moves, the spur gear 45 can rotate. When the spur gear 45 rotates, the other rack plate 44 can drive the positioning plate 41 on the other side to move in the opposite direction. When the positioning plates 41 on both sides move to the appropriate position, the obstruction to the inside of the mounting groove 2 can be released. After the alarm device body 3 is placed inside the mounting groove 2, the positioning plates 41 on both sides can return to their original positions under the action of the four first compression springs 42. Under this action, the alarm device body 3 can be prevented from moving. One side of the surface of the pull ring 43 is provided with an anti-slip sleeve 5. The anti-slip sleeve 5 is made of anti-slip rubber. Under the action of the anti-slip sleeve 5, the pull ring 43 can be pulled easily.

[0024] The limiting mechanism 9 includes an external gear ring 91. The inner wall of the external gear ring 91 is bolted to one side of the surface of the transmission disk 8. When the transmission disk 8 rotates, the external gear ring 91 can rotate. Second compression springs 92 are fixedly connected to both sides of the inner wall of the protective cover 7. Half-gear rings 93 are fixedly connected to the other end of the surfaces of the second compression springs 92 on both sides. The half-gear rings 93 and the external gear ring 91 are located on the same horizontal plane. Under the action of the second compression springs 92 on both sides, the half-gear rings 93 can engage with one side of the surface of the external gear ring 91, thus allowing the external gear ring 91 to rotate. The limit is set to prevent the transmission disc 8 from rotating easily. A pull rod 94 is bolted to one side of the surface of the half-tooth ring 93. One side of the surface of the pull rod 94 is slidably connected to one side of the surface of the protective cover 7. When the pull rod 94 moves, the half-tooth ring 93 can move. When the half-tooth ring 93 moves, the second compression springs 92 on both sides can be compressed. When the half-tooth ring 93 moves to the appropriate position, the limit on the outer tooth ring 91 can be released. The bottom of the half-tooth ring 93 is bolted to the top of the slider 11. Under the action of the slider 11, the movement of the half-tooth ring 93 can be made more stable.

[0025] Working principle: When it is necessary to remove the main body 3 of the alarm device, pull the pull ring 43. When the pull ring 43 moves, it can move the positioning plate 41 on one side. When the positioning plate 41 moves, it can move the rack plate 44 on one side. Then, the movement of the rack plate 44 on one side can drive the spur gear 45 to rotate. Next, the rotation of the spur gear 45 can drive the other rack plate 44 to move the other positioning plate 41 in the opposite direction. At the same time, when the positioning plate 41 moves, it can compress the first compression spring 42. Then, when the positioning plates 41 on both sides move to the appropriate position, they can release contact with the main body 3 of the alarm device. Under this action, the main body 3 of the alarm device can be removed. When it is necessary to change the direction of the horn of the main body 3 of the alarm device, pull the pull rod 94. When the pull rod 94 moves, it can move the half-tooth ring 93. Then, the movement of the half-tooth ring 93 can compress the second compression springs 92 on both sides. Next, when the half-tooth ring 93 moves to the appropriate position, it can disengage from the outer tooth ring 91. Under this action, the limit of the outer tooth ring 91 can be released. Then, the direction of the main body 3 of the alarm device can be rotated.
