[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples consistent with some aspects of this invention as detailed in the appended claims.

[0049] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on or indirectly on the other component. When a component is referred to as "connected to" or "laid on" another component, it can be directly connected to or indirectly connected to the other component.

[0050] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0052] Smoke detectors prevent fires by monitoring smoke concentration and are widely used in various fire alarm systems. They automatically emit alarm signals during the smoke-generating stage when a fire hazard exists, promptly alerting people to extinguish the fire before it escalates. Currently, the installation and removal of existing smoke detectors typically involves using specific tools to install and remove multiple mounting screws. However, the frequent adjustment of these screws during installation or removal is time-consuming and inconvenient for maintenance personnel.

[0053] To solve the aforementioned technical problems, this utility model proposes the following technical approach: Considering that directly installing and disassembling the smoke alarm using mounting screws results in a lengthy installation and disassembly process, the inventor devised a method using a mounting plate and a positioning groove for installation and disassembly of the smoke alarm. A fixing plate is provided on the top of the smoke alarm, with arc-shaped locking blocks on each of the four sides of the fixing plate. A positioning groove is provided above the fixing plate; a positioning ring is provided at the bottom of the positioning groove, with arc-shaped openings on all four sides and arc-shaped grooves adjacent to the arc-shaped openings; a mounting plate is provided on the top of the positioning groove; threaded holes are provided at both ends of the mounting plate, and positioning bolts are installed within the threaded holes. Install the positioning bolts on the mounting plate onto the ceiling through the threaded holes. Then, manually insert the arc-shaped locking block on the fixing plate into the arc-shaped opening on the positioning ring, allowing the arc-shaped locking block to enter the positioning groove. Rotate the fixing plate to move the arc-shaped locking block above the arc-shaped groove, allowing it to enter the groove and receive the locking block. This supports the fixing plate and the smoke alarm, completing the installation. The reverse process is for disassembly. This method avoids frequent adjustments of multiple mounting screws during smoke alarm installation and disassembly, reducing installation and disassembly time and providing convenience for maintenance personnel.

[0054] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that can be solved by the smoke alarm device provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0062] In this embodiment, a positioning ring (201) is provided at the bottom of the positioning groove (200), and the positioning ring (201) is heat-fused to the positioning groove (200). The positioning ring (201) is provided with an arc-shaped opening (202) that matches the arc-shaped locking block (102). The arc-shaped opening (202) is used for the arc-shaped locking block (102) to enter the positioning groove (200) from the positioning ring (201), and then the arc-shaped locking block (102) is moved into the arc-shaped groove (203) by rotating the fixing plate (101). An arc-shaped groove (203) is provided on the adjacent side of each arc-shaped opening (202). The arc-shaped groove (203) is used to receive the rotated arc-shaped locking block (102). The arc-shaped groove (203) matches the arc-shaped locking block (102), and the arc-shaped opening (202) penetrates the upper and lower surfaces of the positioning ring (201).

[0063] The mounting plate (300) has threaded holes (301) at both ends, and positioning bolts (302) are installed in the threaded holes (301).

[0064] In this embodiment, a mounting plate (300) is provided on the top of the positioning groove (200). The mounting plate (300) is used to connect the positioning groove (200) to the ceiling.

The positioning bolts (302) pass through the threaded holes (301) to connect and fix the mounting plate (300) to the ceiling.

[0065] In summary, when installing a smoke alarm, the installation process involves first installing the positioning bolts on the mounting plate onto the ceiling through the threaded holes. Then, manually insert the arc-shaped locking block on the fixing plate into the arc-shaped opening on the positioning ring, allowing the block to enter the positioning groove. Rotating the fixing plate moves the block above the arc-shaped groove, allowing it to fit into the groove and support the block. This provides support for the fixing plate and the smoke alarm, completing the installation. The reverse process is the disassembly step. This method avoids frequent adjustments of multiple mounting screws, reducing installation and disassembly time and providing convenience for maintenance personnel.
