[0025] 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.

[0026] Example

[0027] like Figure 1-4 As shown in the figure, an alarm device according to one embodiment of the present invention includes an alarm body 2 and an alarm button 8 installed at the front end of the alarm body 2. The front end of the alarm body 2 is also equipped with a microphone port 4 and a sound receiving port 5. The alarm body 2 adopts the existing known internal structure of an alarm, such as a power module, a network communication module core processing unit, and a sound pickup unit. A flashing light 3 is set on the top of the alarm body 2. The front end of the alarm body 2 is provided with a control cavity 6. The opening of the control cavity 6 is provided with a rotatable transparent cover plate 7. An alarm button 8 that can trigger an alarm is installed in the groove of the control cavity 6. The transparent cover plate 7 can be completely covered by the rotation axis at the top of the transparent cover plate 7. The bottom of the transparent cover plate 7 is provided with a protrusion. In actual operation, the transparent cover plate 7 can be flipped outward by pushing the protrusion upward.

[0028] The difference is that a set of fixed back plates 1 connected to the alarm body 2 are installed on the back of the alarm body 2. The fixed back plate 1 adopts a plate structure. Back plate mounting strips 9 are symmetrically installed on the upper and lower parts of the fixed back plate 1. Each set of back plate mounting strips 9 has a straight mounting groove on its surface. In actual installation, the back plate mounting strips 9 and the fixed back plate 1 are fixed to the mounting surface at the designated mounting point by expansion bolts or other locking structures through the mounting grooves at the back plate mounting strips 9.

[0029] A symmetrically designed shell slot 11 is provided at the bottom rear of the alarm body 2. The lower half of the front end of the fixing plate 10 is fixed with the fixing plate 10, and both ends of the fixing plate 10 are adapted to the groove shape of the shell slot 11. This allows the alarm body 2 to stand vertically, with the shell slot 11 inserted into the top of the fixing plate 10. A slot top hole 13 is also provided at the top of the groove in the shell slot 11, and a top protrusion 12, which can be inserted into the slot top hole 13, is fixed to the top of the fixing plate 10. In actual connection, the top protrusion 12 needs to be aligned with the slot top hole 13, and the alarm body 2 needs to be pressed down until the top protrusion 12 is fully inserted into the slot top hole 13, and the shell slot 11 and fixing plate 10 are engaged, thus fixing the position of the alarm body 2.

[0030] To further improve the stability of the connection between the alarm body 2 and the fixed back plate 1, the fixed block plate 10 is also provided with a locking mechanism for locking the top protrusion 12 into the slot top hole 13. The locking mechanism includes a rotating screw 14, a screw sleeve 15, and a locking link 16. The rotating screw 14 is installed at the center of the front end of the fixed block plate 10, the screw sleeve 15 is threaded onto the outside of the rotating screw 14, and the locking link 16 is fixed to the side wall of the screw sleeve 15. The fixed block plate 10 has a cavity inside. The rotating screw 14 is rotatably connected to the fixed block plate 10, and the handle of the rotating screw 14 is located on the outside of the fixed block plate 10. The inner wall of the slot top hole 13 has a side hole. The locking link 16 is placed inside the top protrusion 12, and the top of the locking link 16 has an extension that can be inserted into the side hole. When the top protrusion 12 is fully inserted into the slot top hole 13, the extension at the top of the locking link 16 is connected to the side hole of the slot top hole 13. Located on the same straight line, the screw 14 can be rotated by a tool through the exposed handle of the rotating screw 14, allowing the threaded sleeve 15, which is threaded outside the rotating screw 14, to move radially along the rotating screw 14. This causes the locking link 16 to move inside the top protrusion 12. The surface of the top protrusion 12 has an opening that allows the extension of the locking link 16 to slide. Therefore, the extension of the locking link 16 can slide out from the opening and be inserted into the side hole of the top hole 13 of the slot, thus locking the alarm body 2 onto the fixing plate 10. This achieves the combination of the fixing back plate 1 and the alarm body 2. The above method enables the quick installation and disassembly of the alarm body 2 and the fixing back plate 1, facilitating subsequent maintenance of the alarm body 2. A wire hole is provided on the surface of the fixing back plate 1 (not shown in the diagram). The wire hole is used for the circuit connected to the alarm body 2 to pass through and connect to a specific line.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
