[0025] like Figures 1 to 4 As shown, the smoke detector which is easy to install comprises a mounting plate 1, a smoke detector body 2 is fixedly mounted on the bottom of the mounting plate 1, a height adjustment mechanism 3 for connecting to the ceiling is arranged above the mounting plate 1, and a docking assembly 4 for connecting to the height adjustment mechanism 3 is arranged on the top of the mounting plate 1. More specifically, the height adjustment mechanism 3 is fixedly mounted on the ceiling, and the length of the height adjustment mechanism 3 can be freely adjusted, thereby changing the installation height of the mounting plate 1 and the smoke detector body 2. When disassembly and maintenance are required, the mounting plate 1 and the smoke detector body 2 can be disassembled by releasing the connection with the height adjustment mechanism 3 through the docking assembly 4.

[0026] The height adjustment mechanism 3 includes a connecting rod 301, a sleeve 302 is movably sleeved on the surface of the connecting rod 301, a support plate 303 is fixedly connected to the top of the sleeve 302, a mounting hole 304 is formed through the surface of the support plate 303, and a locking assembly for limiting the position of the connecting rod 301 is provided on the surface of the sleeve 302. It should be noted that the support plate 303 can be fixed to the ceiling through the mounting hole 304 and the bolt, and the connecting rod 301 can be pulled to slide on the inner wall of the sleeve 302, and the locking assembly is used to limit the position of the connecting rod 301, so that the height of the mounting plate 1 and the smoke detector body 2 can be limited.

[0027] The locking assembly includes a pin 305, and the pin 305 is movably connected to the sleeve 302. The front end of the pin 305 is fixedly connected to a pull rod 306, and a spring 307 is fixedly connected between the back of the pull rod 306 and the front of the sleeve 302. A positioning hole 308 is opened on the front of the connecting rod 301, and the end of the pin 305 is movably connected to the inner wall of the positioning hole 308. More specifically, by pulling the pull rod 306, the pin 305 is driven to move, and the spring 307 is stretched so that the end of the pin 305 is separated from the inner wall of the positioning hole 308, thereby releasing the limit on the connecting rod 301. After the connecting rod 301 is pulled up and down so that the mounting plate 1 and the smoke detector body 2 are at a suitable height, the pull rod 306 is released. Under the action of the elastic force of the spring 307, the pull rod 306 and the pin 305 will be pulled to move, so that the pin 305 is reinserted into the interior of the positioning hole 308, so that the connecting rod 301 can be limited, and the height of the mounting plate 1 and the smoke detector body 2 can be limited.

More specifically, the double-headed screw 402 is controlled to rotate by the adjustment assembly, and the bent rod 403 is driven to slide along the inner wall of the slide groove 404 under the action of the thread, so that the clamping block 405 can be driven to move, so that the inner wall of the clamping block 405 is separated from the surface of the connecting rod 301, and the mounting plate 1 and the smoke detector body 2 can be quickly disassembled.

[0030] The adjustment assembly includes a worm 406, and the worm 406 is rotatably connected to the installation box 401, a knob 407 is fixedly connected to the front end of the worm 406, a worm wheel 408 is fixedly sleeved on the surface of the double-headed screw 402, and the worm wheel 408 is meshed with the worm 406. It should be noted that by rotating the knob 407, the worm 406 is driven to rotate, thereby driving the worm wheel 408 meshed with it to rotate, and the double-headed screw 402 can be controlled to rotate.

[0031] In summary: the height adjustment mechanism 3 is fixedly installed on the ceiling, and the length of the height adjustment mechanism 3 can be freely adjusted, so as to change the installation height of the mounting plate 1 and the smoke detector body 2. When disassembly and maintenance are required, the connection with the height adjustment mechanism 3 is released through the docking component 4, and the mounting plate 1 and the smoke detector body 2 can be disassembled. During use, the effect of freely adjusting the installation height of the smoke detector is achieved, so that it can adapt to ceilings of different heights, so that the smoke detector can obtain a suitable smoke monitoring range, and the practicality is good.
