[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] like Figures 1-8 As shown, a smoke alarm for disassembly and maintenance includes a mounting bracket 1 and a smoke alarm body 2. The smoke alarm body 2 is detachably mounted on the mounting bracket 1. The smoke alarm body 2 is a prior art device, which mainly consists of a housing 21, a smoke sensor, an electronic speaker, a battery, a microprocessor, and other components.

[0026] Specifically, a connecting platform 22 is provided on the top of the housing 21. The connecting platform 22 is integrally formed and fixed to the housing 21. A connecting hole 11 is opened at the center of its top surface. A locking hole 12 is opened at the bottom of the connecting hole 11 and is concentrically arranged with the connecting hole 11. The locking hole 12 and the connecting hole 11 form a stepped hole. The diameter of the locking hole 12 is larger than the diameter of the connecting hole 11. A guide groove 3 is opened on one side of the connecting hole 11 and the locking hole 12. The guide groove 3 is opened from one side wall of the connecting platform 22 towards the center of the connecting platform 22. It communicates with the connecting hole 11 and the locking hole 12. Its cross-section is inverted "T" shaped, that is, the guide groove 3 is a stepped groove. The stepped surface of the stepped hole formed by the locking hole 12 and the connecting hole 11 is higher than the stepped surface of the stepped groove of the guide groove 3. The stepped surface of the stepped hole and the stepped side of the guide groove 3 surround each other to form an upwardly concave circular limiting groove 13.

[0027] Specifically, the mounting bracket 1 includes a top plate 41 and a connecting column 51. The top plate 41 is a quadrilateral thin plate, and its material can be stainless steel or other metal materials, or a high-strength plastic plate. Four mounting holes 43 are evenly distributed around its center circumference. Bolts and nuts are inserted through the mounting holes 43 to fix the top plate 41 to the wall. The connecting column 51 is fixedly connected to the bottom center of the top plate 41. The connecting column 51 is a circular column, and a mounting bracket 52 is rotatably mounted on it. The mounting bracket 52 is a circular platform with a mounting... The mounting cavity 53 houses a bearing 54. A socket 55 is provided at the top of the mounting cavity 53. The connecting post 51 passes through the socket 55 and transitions into the bearing 54. The diameter of the socket 55 is smaller than the outer diameter of the connecting post 51, and the area smaller than the diameter of the socket 55 forms a fastening part 56. A fastening groove 57 is provided on the side wall of the connecting post 51. The fastening groove 57 is an annular groove circumferentially formed along the connecting post 51. The fastening part 56 can be inserted into the fastening groove 57 to prevent the connecting post 51 and the retaining plate 52 from separating.

[0028] Furthermore, the connecting post 51 is inserted into the connecting hole 11, and the locking platform 52 is installed in the locking hole 12, with its top inserted into the limiting groove to restrict the sliding of the locking platform 52 relative to the connecting platform 22.

[0029] Furthermore, a stop block 61 is provided in the guide groove 3. The stop block 61 is generally made of hard rubber or plastic. Its main body, which is inserted into the guide groove 3, is a stepped block with an inverted "T" shaped cross section. The stop block 61 can be inserted into the guide groove 3 from the side opening of the guide groove 3. A retaining groove 62 is provided at one end of the stop block 61 inserted into the guide groove 3. The retaining groove 62 is semi-circular in shape, and its two sides are provided with rounded chamfers to avoid the side edge of the retaining groove 62 being squeezed and deformed, which would affect the installation and assembly of the stop block 61 and the locking platform 52. A lever 63 is integrally fixed at the end of the stop block 61 away from the connecting platform 22. The lever 63 extends to both sides of the stop block 61 and its width is greater than that of the stop block 61. At the same time, there is a lever gap between it and the connecting platform 22 to facilitate lever 63 during disassembly. Multiple parallel friction grooves 64 are provided on the two end faces of the lever 63.

[0030] The specific implementation process of this utility model is as follows: When installing the smoke alarm body 2, the mounting bracket 1 is pre-installed and fixed on the corresponding wall. Then, the smoke alarm body is inserted along the guide groove 3, and the mounting plate 52 is inserted into the mounting hole 12. By inserting the stop block 61 into the guide groove 3, the mounting plate 52 is pressed down, thus completing the installation of the smoke alarm body 2. At the same time, due to the weight of the smoke alarm body 2, the smoke alarm body 2 will move down a certain distance. The top of the mounting plate 52 is inserted into the limiting groove to restrict the sliding of the mounting plate 52 relative to the connecting platform 22.

[0031] When performing maintenance or replacement, pull the lever 63 to remove the stop block 61, then lift the smoke alarm body 2, and move the smoke alarm body 2 laterally to separate it from the connecting column 51, thus completing the quick disassembly.

[0032] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. The present utility model can be used in similar products. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
