A rotating clamping block 3014 is installed on the outer side of the sleeve 3011, and a plurality of elastic components 4 are installed on the docking ring 202. The elastic component 4 includes a limit block 403 slidably installed between the upper clamping seat 301 and the lower push block 302. The upper clamping seat 301 is limited by the limit block 403 to complete the fixation of the lower plate 1, and a fire alarm 5 is installed at the lower end of the lower plate 1.

[0023] Reference Figure 2The push-down block 302 includes an extrusion sleeve 3021 installed on the lower plate 1, and an arc-shaped surface is cut on the upper end of the connecting ring 3012, and an arc-shaped groove adapted to the extrusion sleeve 3021 is provided at the bottom of the connecting ring 3012, so as to facilitate the fitting of the extrusion sleeve 3021 and the connecting ring 3012 to avoid a gap. A rotation slot 3022 is provided on the inner side of the extrusion sleeve 3021, and the fitting and separation of the extrusion sleeve 3021 and the connecting ring 3012 can be achieved by rotating the rotation slot 3022 and the rotation block 3014. The disassembly failure caused by the downward movement of the upper clamping seat 301 and the push-down block 302 can be avoided.

[0024] Reference Figure 3 The upper clamping seat 301 includes a positioning ring 3013 slidably installed in the extrusion sleeve 3021. The positioning ring 3013 is provided with a plurality of positioning grooves adapted to the positioning block 3023. By docking the positioning block 3023 with the positioning grooves on the positioning ring 3013, relative rotation between the upper clamping seat 301 and the lower push block 302 can be avoided after installation.

[0025] Reference Figure 3 The elastic component 4 includes a supporting ear 401 installed on the mounting plate 201, and a reset spring 402 is installed between the limit block 403 and the supporting ear 401. The reset spring 402 allows the elastic force of the reset spring 402 to drive the limit block 403 to reset, thereby allowing the limit block 403 to be engaged and fixed with the connecting ring 3012.

[0026] Reference Figure 2 The limit block 403 includes a block 4031 that slides through the docking ring 202. The lower side of the block 4031 is installed with an inclined surface to facilitate the block 4031 to slide and avoid when it is squeezed and contacted with the connecting ring 3012 and the extrusion sleeve 3021. An arc-shaped protrusion 4032 is installed on the block 4031. The bottom circumference of the connecting ring 3012 is provided with a tooth groove that is compatible with the connecting ring 3012. After the limit block 403 is engaged with the upper clamping seat 301, the docking ring 202 and the upper clamping seat 301 can be prevented from relative rotation.

[0027] The implementation principle of the alarm device for building security that is easy to maintain in the embodiment of the present application is as follows: during installation, the lower plate 1 is pushed up by the tool rod so that the upper arc surface of the upper clamping seat 301 is docked with the docking ring 202, which can facilitate the upper clamping seat 301 to slide into the docking ring 202 for easy positioning. The upper clamping seat 301 continues to move upward, so that the limit block 403 on the outer side of the squeeze is moved outward, and then the tool rod is retracted, and the push-down block 302 moves downward, and the push-down block 302 is supported by the elastic force of the support spring 303, so that the support spring 303 is separated from the push-down block 302. At this time, the limit block 403 is clamped with the upper clamping seat 301 under the elastic force of the reset spring 402, and the positioning block 3023 is aligned with the positioning ring 3013 through the rotating clamping block 3014 and the rotating clamping groove guide. The groove is connected so that the upper clamping seat 301 and the lower push block 302 form a horizontal limit. Due to the characteristics of the arc-shaped protrusion 4032, under the action of gravity of the connecting ring 3012, the arc-shaped protrusion 4032 slides into the tooth groove to form a positioning. When disassembling, the lower plate 1 is pushed up through the tool rod so that the upper arc surface of the lower push block 302 is docked with the limit block 403, so that the limit block 403 on the outside of the squeeze is moved outward, and the upper clamping seat 301 is fitted with the lower push block 302. Then the tool rod is rotated so that the rotating clamping block 3014 enters the horizontal section of the rotating clamping slot, and the lower push block 302 and the upper clamping seat 301 are formed into one body. The tool rod is retracted, and the lower push block 302 and the upper clamping seat 301 move downward synchronously, which can prevent the limit block 403 from entering between the upper clamping seat 301 and the lower push block 302, and the operation is more convenient.
