Once a fire occurs, it is easy to encounter unfavorable factors such as untimely firefighting, lack of fire-fighting equipment, panic of people on the scene, and slow escape. In addition, a large amount of coal is often stored in ports and power fields, and the stored coal may also catch fire due to spontaneous combustion. In these occasions, smoke alarms that detect smoke are very necessary. Smoke alarms usually consist of two parts: one is the induction sensor for detecting smoke, and the other is an electronic speaker with a very loud sound.

[0022] It should be noted that a spring telescopic rod 53 is rotatably connected between the anti-seismic plate 51 and the base plate 55. When people are active in the upper floor, the bottom of the ceiling will vibrate slightly. At this time, through the setting of the spring telescopic rod 53, the spring telescopic rod 53 can buffer the vibration force applied to the smoke alarm body 3, effectively avoiding the smoke alarm body 3 from loosening due to shaking back and forth and affecting its later use, thereby extending the service life of the smoke alarm body 3 and greatly improving the safety performance of the entire device.

[0023] Furthermore, the clamping mechanism 6 includes a handle 61, a transmission worm 62, a transmission worm wheel 63, a bidirectional screw 64 and a movable seat 65.

[0025] Furthermore, the swing mechanism 7 includes a swing ball 71, a limit spring 72, a limit column 73, a sliding bar 74, a rotating shaft 75, a torsion spring 76 and a ratchet plate 77. The limit springs 72 are fixedly connected to the inner walls of the left and right sides of the fixed frame 4 on the upper side of the mounting plate 1, and the swing ball 71 is fixedly connected between the two limit springs 72. The upper part of the outer wall of the swing ball 71 is fixedly connected to the limit column 73, and the front side of the lower end of the limit column 73 is fixedly connected to the sliding bar 74. The right side of the inner cavity of the sliding bar 74 is fixedly connected to the rotating shaft 75, and the middle part of the outer wall of the rotating shaft 75 is rotatably connected to the ratchet plate 77.

A limiting groove 41 is provided on the side wall of the fixing frame 4 , and the limiting column 73 slides in the inner cavity of the limiting groove 41 .

[0026] When the sliding bar 74 moves to the right, under the action of the torsion spring 76, the ratchet plate 77 can drive the ratchet wheel 82 to rotate the bidirectional threaded groove rod 81. When the sliding bar 74 moves to the left, under the action of the torsion spring 76, the ratchet plate 77 cannot drive the ratchet wheel 82 to rotate the bidirectional threaded groove rod 81, so that the bidirectional threaded groove rod 81 can always rotate in one direction.

[0027] Further, the cleaning mechanism 8 includes a bidirectional threaded groove rod 81, a ratchet 82, a sliding sleeve 83, a limit block 84, a cleaning brush 85, a limit rod 86 and a limit sleeve 87. The bidirectional threaded groove rod 81 is rotatably connected between the upper and lower fixed frames 4, and the limit rod 86 is rotatably connected between the upper and lower fixed frames 4. The ratchet 82 is fixedly connected to the upper part of the outer wall of the bidirectional threaded groove rod 81, and the ratchet 82 is meshed and connected with the ratchet plate 77. The limit block 84 is slidably connected to the inner cavity of the threaded groove wall of the bidirectional threaded groove rod 81, and the sliding sleeve 83 is slidably connected to the middle part of the outer wall of the bidirectional threaded groove rod 81, and the limit block 84 is fixedly connected to the inner cavity of the sliding sleeve 83.

[0028] It should be noted that when the bidirectional threaded groove rod 81 rotates, the limit block 84 is connected by slidingly connecting the inner cavity of the threaded groove wall of the bidirectional threaded groove rod 81, and the limit block 84 is fixed to the inner cavity of the sliding sleeve 83 and the setting of the limit rod 86 and the limit sleeve 87. When the bidirectional threaded groove rod 81 rotates, the limit block 84 can drive the sliding sleeve 83 to slide back and forth on the outer wall of the bidirectional threaded groove rod 81, and a cleaning brush 85 is fixedly connected to the left side of the outer wall of the sliding sleeve 83. At this time, the cleaning brush 85 will also reciprocate to realize the function of cleaning the surface of the smoke alarm body 3, ensuring that it always detects the environment with high performance, avoiding the need for manual regular maintenance of the smoke alarm body 3, saving resource loss, and greatly improving the practicality of the entire device.

[0029] Working principle: When installing the smoke alarm body 3, the worker needs to place the smoke alarm body 3 on the end face of the adjustment box 2. At this time, turning the handle 61 can rotate the transmission worm 62, and the transmission worm 62 is meshed with the transmission worm wheel 63, and the transmission worm wheel 63 is fixedly connected with the bidirectional screw 64. At this time, the transmission worm 62 will drive the transmission worm wheel 63 to rotate the bidirectional screw 64. The threads on both sides of the bidirectional screw 64 are in opposite directions, and the moving seat 65 is threadedly connected with the bidirectional screw 64. At this time, under the limiting constraint of the slide groove 21 on the slide column 22, the moving seats 65 on the left and right sides will be able to drive the slide column 22 to approach each other. At this time, the preliminary installation of the smoke alarm body 3 can be achieved in conjunction with the shockproof mechanism 5. Then, through the positioning holes 11 set around the lower end face of the mounting plate 1, the worker can quickly fix the entire device under the ceiling of the building, which greatly improves the work efficiency of the workers. A spring telescopic rod 53 is rotatably connected between the anti-vibration plate 51 and the base plate 55. When people move in the upper floor, the bottom of the ceiling will vibrate slightly. At this time, the spring telescopic rod 53 can buffer the vibration force applied to the smoke alarm body 3, effectively avoiding the smoke alarm body 3 from loosening due to shaking back and forth, which affects the subsequent use, prolongs the service life of the smoke alarm body 3, and greatly improves the safety performance of the entire device; When the ceiling of the building vibrates slightly, the swing ball 71 will swing left and right under the soft force of the limit spring 72 through the setting of the limit spring 72. Since the limit column 73 slides in the inner cavity of the limit groove 41, the limit column 73 is fixedly connected to the sliding bar 74, and the swing ball 71 can drive the limit column 73 to move the sliding bar 74 left and right. When the sliding bar 74 moves to the right, under the action of the torsion spring 76, the ratchet plate 77 can drive the ratchet 82 to rotate the bidirectional thread groove rod 81. When the sliding bar 74 moves to the left, under the action of the torsion spring 76, the ratchet plate 77 cannot drive the ratchet 82 to rotate the bidirectional thread groove rod 81, so that the bidirectional thread groove rod 81 can always rotate in one direction. When the bidirectional threaded groove rod 81 rotates, the limit block 84 is slidably connected to the inner cavity of the threaded groove wall of the bidirectional threaded groove rod 81, and the limit block 84 is fixed to the inner cavity of the sliding sleeve 83 and the setting of the limit rod 86 and the limit sleeve 87. When the bidirectional threaded groove rod 81 rotates, the limit block 84 can drive the sliding sleeve 83 to slide back and forth on the outer wall of the bidirectional threaded groove rod 81, and a cleaning brush 85 is fixedly connected to the left side of the outer wall of the sliding sleeve 83. At this time, the cleaning brush 85 will also reciprocate to realize the function of cleaning the surface of the smoke alarm body 3, ensuring that it always detects the environment with high performance, avoiding the need for manual regular maintenance of the smoke alarm body 3, saving resource loss, and greatly improving the practicality of the entire device.

Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
