[0020] 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.

[0021] like Figure 1-6 As shown, this embodiment proposes a fire alarm device for detection, including a smoke alarm 1. The top of the smoke alarm 1 has a mounting groove 8 and a mounting plate 2, with the bottom of the mounting plate 2 located in the mounting groove 8. The surface of the mounting plate 2 has several L-shaped grooves 5. The inner wall of the mounting groove 8 is fixedly connected to a locking block 9 corresponding to each L-shaped groove 5, and the locking block 9 is slidably disposed in the corresponding L-shaped groove 5. With the above structure, simply insert the locking block 9 into the corresponding L-shaped groove 5 and then rotate it counterclockwise to position the locking block 9 in the L-shaped groove 5, effectively preventing the smoke alarm 1 from falling off, thus quickly assembling and fixing the smoke alarm 1. The structure is simple, convenient for subsequent replacement, and also saves production costs. Each L-shaped groove 5 is provided with a positioning mechanism for limiting the locking block 9. With the setting of the positioning mechanism, the locking block 9 can be prevented from easily sliding in the L-shaped groove 5, thus ensuring the stability of the smoke alarm 1 after it is fixed on the mounting plate 2.

[0022] like Figure 2 and Figure 6As shown, the positioning mechanism includes a top groove 14, which is formed on the inner top wall of the L-shaped groove 5. A limiting block 6 is slidably provided on the inner wall of the top groove 14. A second compression spring 15 is fixedly connected to the top of the limiting block 6, and the second compression spring 15 is fixedly connected to the inner top wall of the top groove 14. The limiting block 6 extends into the L-shaped groove 5. Both sides of the limiting block 6 are inclined. With the above structure, when the locking block 9 slides in the L-shaped groove 5, the locking block 9 will push the limiting block 6 to slide into the top groove 14 until the locking block 9 is located on the left side of the limiting block 6. Then, the limiting block 6 can extend into the L-shaped groove 5 under the elastic force of the second compression spring 15, which plays a blocking role on the locking block 9 and prevents the locking block 9 from sliding easily in the L-shaped groove 5. Only by manually twisting the smoke alarm 1 clockwise can the locking block 9 be moved in the L-shaped groove 5.

[0023] like Figures 1 to 5 As shown, the side of the mounting plate 2 is fixed with a first indicator plate 3 corresponding to each L-shaped slot 5, and the side of the smoke alarm 1 is fixed with a second indicator plate 4 corresponding to each locking block 9. With the above structure, it is easier for personnel to insert the locking block 9 into the corresponding L-shaped slot 5. When the first indicator plate 3 and the second indicator plate 4 are aligned, the locking block 9 is aligned with the corresponding L-shaped slot 5.

[0024] like Figure 2 and Figure 5 As shown, a bottom groove 10 is provided on the bottom surface of the mounting plate 2. A first compression spring 13 is fixedly connected to the inner top wall of the bottom groove 10. A pressing plate 7 is fixedly connected to the bottom end of the first compression spring 13. The pressing plate 7 is slidably disposed in the bottom groove 10 and is pressed into the mounting groove 8. With the above structure, when the smoke alarm 1 is fixed on the mounting plate 2, the pressing plate 7 is pressed downward into the mounting groove 8 by the elastic force of the first compression spring 13, which further improves the limiting stability of the locking block 9 in the L-shaped groove 5 and prevents the smoke alarm 1 from easily rotating on the mounting plate 2.

[0025] like Figure 5 As shown, two opposing guide plates 11 are fixedly connected to the inner wall of the bottom groove 10, and two guide rods 12 are fixedly connected to the extrusion plate 7. The two guide rods 12 are slidably disposed in the two guide plates 11 respectively. With the above structure, the stability of the extrusion plate 7 during the up and down movement can be guaranteed, and the extrusion plate 7 will not swing when it extends below the mounting plate 2. The extrusion plate 7 is guided and slid within the guide plates 11 by the guide rods 12, and the extrusion plate 7 is extruded into the bottom groove 10 by the subsequent smoke alarm 1.

[0026] The working principle and usage process of this utility model are as follows: First, the smoke alarm 1 is installed in the mounting hole of the building using screws. Then, a person holds the smoke alarm 1 and clips it onto the bottom of the mounting plate 2. At this time, the person observes that the second indicator plate 4 is aligned with the first indicator plate 3, so that the locking block 9 can be smoothly inserted into the L-shaped groove 5. At this time, the smoke alarm 1 pushes the pressing plate 7 upward and moves it. Then, the smoke alarm 1 is rotated counterclockwise, so that the locking block 9 will push the limiting block 6 into the top groove 14 during the movement. Once the locking block 9 is away from the limiting block 6, the smoke alarm 1 can be assembled and fixed. The operation is more convenient. When the smoke alarm 1 needs to be disassembled, replaced or maintained in the future, it is only necessary to rotate the smoke alarm 1 clockwise, so that the locking block 9 pushes the limiting block 6 into the top groove 14. Finally, the smoke alarm 1 is pulled downward. The operation is more convenient and no additional tools are required.

For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
