The springs 3 are movably connected to the outer ends of the adjacent telescopic columns 2. A rubber anti-slip strip 5 is provided on the side of the extrusion seat 4 close to the center of the base 1. A limiting slide 7 is provided on the rear wall of the base 1. A slide groove 8 is provided on the rear side of the fire safety indication shell 6. The limiting slide 7 is slidably connected to the slide groove 8. Evenly distributed mounting seats 12 are provided on the rear side of the base 1. When performing fire safety indication, the device is first fixed to the specified position with screws through the mounting seats 12, and then Then, the fire safety indicator shell 6 is moved vertically downward, and the left and right sides of the fire safety indicator shell 6 are in contact with the adjacent extrusion seat 4. The extrusion seat 4 is compressed, and the telescopic end of the telescopic column 2 and the spring 3 are contracted. As the fire safety indicator shell 6 continues to move downward, the slide groove 8 is in vertical sliding contact with the limit slide seat 7. The fire safety indicator shell 6 is longitudinally limited by the sliding connection between the slide groove 8 and the limit slide seat 7. The compression elastic force of the spring 3 enables the extrusion seat 4 to vertically limit the fire safety indicator shell 6, which is convenient for later disassembly and maintenance. The rubber anti-slip strip 5 further avoids vertical sliding between the extrusion seat 4 and the fire safety indicator shell 6 by increasing the contact friction. The luminous fire safety indicator sign is fixed to the fire safety indicator part by elastic extrusion, which is convenient for later maintenance and replacement.

[0023] Wherein: it also includes a single chip microcomputer 10, which is arranged on the rear wall of the fire safety indication shell 6, the input end of the single chip microcomputer 10 is electrically connected to the external power supply, and the output end of the single chip microcomputer 10 is electrically connected to the input end of the energy-saving lamp 9, which is convenient for controlling electrical components;

The luminous fire safety indication sign adopts dual power supply, and the backup power supply can be used when the power supply fails, which is easy to use.

[0025] The working principle of a luminous fire safety indication sign provided by the utility model is as follows: when performing a fire safety indication, firstly, the device is fixed to the specified position by screws through the mounting seat 12, and then the fire safety indication shell 6 is moved vertically downward, and the left and right sides of the fire safety indication shell 6 are in contact with the adjacent extrusion seat 4, the extrusion seat 4 is compressed, and the telescopic end of the telescopic column 2 and the spring 3 are contracted. As the fire safety indication shell 6 continues to move downward, the slide groove 8 vertically slides in contact with the limit slide 7, and the fire safety indication shell 6 is longitudinally limited by the sliding connection between the slide groove 8 and the limit slide 7, and the spring 3 is used to press the fire safety indication shell 6. The compression elastic force of the spring 3 allows the extrusion seat 4 to limit the vertical movement of the fire safety indicator shell 6, which makes it easy to disassemble and repair later. The rubber anti-slip strip 5 further avoids vertical sliding between the extrusion seat 4 and the fire safety indicator shell 6 by increasing the contact friction.
