[0007] Furthermore, a bayonet is provided on the limit plate, and a limit unit is fixedly connected to the fixed back plate. The limit unit includes a connecting plate fixedly connected to the fixed back plate, an adjusting rod is slidably provided on the connecting plate, a tightening spring is sleeved on the adjusting rod, and a limit block that cooperates with the bayonet is fixedly connected to one end of the adjusting rod.

[0008] Furthermore, the other end of the adjusting rod is fixedly connected to an anti-slip pull rod arranged on the other side of the connecting plate.

[0009] Furthermore, an audible and visual alarm is fixedly connected to the fixed back plate.

[0010] Furthermore, a paraffin support rod penetrates the lower part of the fire alarm body, a trigger rod plugged into the fire alarm body is fixedly connected to the upper end of the paraffin support rod, and an alarm switch matching the trigger rod is fixedly connected to the fire alarm body.

[0011] Furthermore, the alarm switch is electrically connected to the sound and light alarm.

[0012] The beneficial effects achieved by the utility model using the above structure are as follows:

[0013] 1. By setting up an external protection mechanism that is easy to install and disassemble, it can effectively avoid the problem of alarm equipment being damaged by uncertain factors such as wild animals in public environments;

[0014] 2. By setting the paraffin structure to melt to physically trigger the alarm, the timeliness of the alarm affected by equipment damage can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model proposes a fire alarm device for public safety protection, including a mounting base 1, a fixed back plate 2 is fixedly connected to the mounting base 1, a card slot 3 is opened on the fixed back plate 2, an external environment protection grid 4 is inserted into the card slot 3, a limit plate 5 is fixedly connected to the external environment protection grid 4 and is arranged through the card slot 3, a transparent cover plate 6 is fixedly connected to the front of the external environment protection grid 4, a support frame 7 is fixedly connected to the mounting base 1, and a fire alarm body 8 is fixedly connected to the support frame 7.

[0021] The limit plate 5 is provided with a bayonet 9, and the fixed back plate 2 is fixedly connected to a limit unit, and the limit unit includes a connecting plate 10 fixedly connected to the fixed back plate 2, and an adjusting rod 11 is slidably provided on the connecting plate 10, and a tightening spring 12 is sleeved on the adjusting rod 11, and one end of the adjusting rod 11 is fixedly connected to a limit block 13 that is plugged into the bayonet 9; the other end of the adjusting rod 11 is fixedly connected to an anti-slip pull rod 14 arranged on the other side of the connecting plate 10.

[0022] A paraffin support rod 16 penetrates the lower part of the fire alarm body 8, and a trigger rod 17 inserted into the fire alarm body 8 is fixedly connected to the upper end of the paraffin support rod 16. An alarm switch 18 matching the trigger rod 17 is fixedly connected to the fire alarm body 8.

[0023] The fixed back plate 2 is fixedly connected with an audible and visual alarm 15 ; the alarm switch 18 is electrically connected with the audible and visual alarm 15 .

[0024] When in use, after the user has installed and fixed the mounting base 1, the external environment protection grid frame 4 can be assembled and installed by using the limit plate 5 through the card slot 3, and the anti-slip pull rod 14 can be pulled to make the adjustment rod 11 drive the tightening spring 12 to contract. After the anti-slip pull rod 14 is released, the elastic potential energy of the tightening spring 12 pushes the limit block 13 and the adjustment rod 11 outward, so that the limit block 13 is clamped in the bayonet 9 for rapid limit, which is convenient for disassembly and maintenance inspection;

[0025] The sound and light alarm 15 can effectively prevent damage in public environments and external environments, and provide protection functions for the equipment;

[0026] When a fire alarm occurs, the wax support rod 16 melts under the action of heat, and the trigger rod 17 that loses its support falls down, and cooperates with the alarm switch 18 to control the sound and light alarm 15 to turn on, and sound and light alarm is issued;
