[0002] With the development of economy and society, fires have also increased. Fire management and fire technology have kept pace with the times and continued to develop. The fire prevention and control of fires have become increasingly important. Fire safety alarm devices are key life safety equipment. They are mainly used to detect fire or smoke and sound an alarm when a fire is found to remind people to evacuate in time and notify relevant rescue departments. The fire alarm device is one of the most important means to prevent fires.

[0003] Smoke detectors, sound and light alarms, etc. are the most common fire safety alarm devices. Existing fire alarm devices are installed by fixing with bolts during installation, and the alarm devices are directly installed on the wall or ceiling. When the alarm device is damaged and needs to be repaired or replaced, multiple bolts need to be removed, which takes a lot of time. There is a problem that disassembly and maintenance are more troublesome, which is not conducive to rapid repair and replacement operations. For this reason, we propose a fire safety alarm device to solve the above problems. Utility Model Content

The bottom surface of the connecting tube 3 is fixedly connected with An alarm monitoring body 6 is connected, and two sound and light alarms 7 are fixedly connected to the outer surface of the alarm monitoring body 6. The bidirectional screw 13 can be rotated by using the turning handle 9, so that the threaded square plate 14 and the clamping plate 15 can be moved closer to or away from each other, thereby achieving the purpose of limiting or releasing the limit of the L-shaped support plate 11, facilitating the disassembly and replacement of the alarm monitoring body 6 and the connecting tube 3, and facilitating the rapid maintenance and replacement operations thereon. It has the advantage of simpler replacement operations, greatly saving maintenance and replacement time, and ensuring that the alarm monitoring body 6 can be used normally, so as to ensure the effectiveness and reliability of the alarm device.

[0022] The inner bottom wall of the connecting tube 3 is fixedly connected with a signal transceiver module 4 and a control processor 5, respectively. The alarm monitoring body 6 and the sound and light alarm 7 are electrically connected to the control processor 5 through wires. The signal transceiver module 4 is electrically connected to the control processor 5 through wires. By connecting with the external background through the signal transceiver module 4, the signal monitored by the alarm monitoring body 6 can be quickly transmitted to the background personnel and related personnel, so that it is convenient to timely understand the alarm information and play a better alarm reminder role. The outer surface of the top installation box 1 is fixedly connected with two mounting frames 10, which is convenient for fixing the use position of the top installation box 1 and improving the stability of use. The inner bottom wall of the top installation box 1 is fixedly connected with two support rods 16, and the top ends of the two support rods 16 are fixedly connected with a circular sleeve 17, and the outer surface of the bidirectional screw 13 is rotatably connected to the inside of the circular sleeve 17. The thread directions of the front and rear ends of the bidirectional screw 13 are in opposite directions, and it is rotated in the circular sleeve 17, which can support it and ensure the stability of the bidirectional screw 13.

[0023] Two guide rails 20 are fixedly connected to the inner wall of the top installation box 1, and two transmission connecting plates 21 are slidably connected inside each guide rail 20.

[0025] The top installation box 1 is installed in the use position through the installation frame 10. During installation, the support plate 2 and the L-shaped support plate 11 can be moved into the top installation box 1 through the through opening 8, and the positioning plug rod 19 will be inserted into the plug-in cylinder 18. Then, the bidirectional screw 13 is rotated by the turning handle 9. Since the two thread directions of the two bidirectional screws 13 are in opposite directions, the two threaded square plates 14 can be moved closer to each other or away from each other, so that the two clamping plates 15 can be used to move closer to each other, so that the clamping plates 15 can be moved below the L-shaped support plate 11, and then the L-shaped support plate 11 can be limited, so that the installation is more convenient. During use, the alarm monitoring body 6 is used to monitor the on-site situation. When an abnormal situation occurs, the monitoring signal will be sent to the control processor 5, and the signal transceiver module 4 will issue an alarm notification to the relevant parts after processing, and then the sound and light alarm 7 will sound an alarm, so as to realize the alarm reminder to the personnel. When replacement and maintenance are required, the bidirectional screw 13 is rotated in the opposite direction to disassemble the alarm monitoring body 6 and the connecting cylinder 3.
