The rotation of the half gear 20 also drives the movable rod 19 to rotate. The rotation of the movable rod 19 drives the first reflector 21 to deflect with the movable rod 19 as the axis. The first reflector 21 deflects to the outside of the light-transmitting groove 17. When the second tooth plate 16 is separated from the half gear 20 and no longer meshes, the first reflector 21 deflects to 100° and stops deflecting.

[0040] Siren 22 is fixedly installed inside the four grooves. The size of the four sirens 22 is the same as that of the grooves. The four sirens 22 are all provided with first switches 23. One side of the four first switches 23 extends to one side outside the grooves. The second reflectors 26 are slidably inserted inside the four sliding grooves 25. The reflective surface of the second reflector 26 is green. The second reflector 26 is in contact with the first switch 23. When the second reflector 26 is separated from the first switch 23 and is not in contact, the sirens 22 make a sound. Slide grooves are provided on both sides of the four sliding grooves 25. Slide blocks are slidably connected inside the two slide grooves. The second reflector 26 is fixedly connected between the two slide blocks.

The outer walls of the four first reflectors 21 and the four second reflectors 26 close to the lampshade 1 are all provided with a plurality of concave grooves 32. When the light plate 21 is deflected, the third rotating rod 28 is deflected by the first reflector 21 and tilted from the vertical state. At this time, the third rotating rod 28 moves along the sliding groove 3 27, and the third rotating rod 28 can move the second reflector 26 from the sliding groove 25 to the outside of the sliding groove 25. When the second reflector 26 moves inside the sliding groove 25, the second reflector 26 does not contact the first switch 23, the alarm 22 sounds, and the second reflector 26 is affected by the length of the third rotating rod 28. Due to the limitation of the width, a part of the second reflector 26 is left in the second sliding groove 25 to support the second reflector 26. The first reflector 21 and the second reflector 26 are unfolded to increase the light area reflected by the emergency light 6 when it is irradiated. The second reflector 26 is green in color, making the light more conspicuous and the position of the light can be found more quickly. When the emergency light 6 is irradiated on the surface of the concave groove 32, the light is refracted on the surfaces of multiple concave grooves 32 to increase the diffusion area of ​​the light, and people are evacuated according to the light and sound.

[0041] An L-shaped block 29 is fixedly connected to the top of the first tooth plate 15, and a backup power supply 30 is fixedly connected to the top of the lampshade 1. The backup power supply 30 is connected to the emergency light 6 through a wire. A second switch 31 is provided on the side of the backup power supply 30 close to the L-shaped block 29. When the first tooth plate 15 descends, the L-shaped block 29 is driven to descend at the same time. When the L-shaped block 29 touches the second switch 31, the backup power supply 30 is started to supply power to the emergency light 6 to turn it on.

[0042] Wherein, the first switch and the second switch are both lock-free push button switches;

[0043] A mounting block is provided on the top of the lampshade 1, and a plurality of sound-transmitting grooves 24 are connected with the sliding groove 25.

The lampshade 1 is installed at the bottom of the ceiling through the mounting block. The alarm sound reverberates inside the sliding groove 25 and then diffuses the alarm sound through the plurality of sound-transmitting grooves 24, so that people can hear the alarm sound better.

[0044] Working principle: the lampshade 1 is installed at the bottom of the ceiling through the mounting block. When there is an emergency power outage, the electric telescopic rod 3 has no power supply. The LED light board 4 drives the output end of the electric telescopic rod 3 to descend synchronously through its own gravity. When the LED light board 4 descends, it drives the first tooth plate 15 to descend. When the first tooth plate 15 descends, it also drives the L-shaped block 29 to descend. When the L-shaped block 29 touches the second switch 31, the backup power supply 30 is started to supply power to the emergency light 6 to turn it on. At the same time, the first tooth plate 15 drives the toothed wheel 14 to mesh and drive, thereby driving the toothed wheel 14 to rotate. When the toothed wheel 14 rotates, it drives the second bevel gear 13 to rotate through the rotating rod 12. The rotation of the second bevel gear 13 drives the first bevel gear 11 to rotate. The meshing transmission drives the first bevel gear 11 to rotate, and the rotation of the first bevel gear 11 drives the second rotating rod 8 to rotate at the same time. When the second rotating rod 8 rotates, the first rotating rod 7 is also rotated through the transmission of the belt 10. When the second rotating rod 8 and the first rotating rod 7 rotate, the brush plate 9 is driven to descend to clean the dust on the surface of the emergency light 6, so that the emergency light 6 can provide a good lighting effect. When the first tooth plate 15 descends, the second tooth plate 16 is driven to descend synchronously. When the second tooth plate 16 descends, the half gear 20 is meshed and driven, thereby driving the half gear 20 to rotate. The rotation of the half gear 20 drives the movable rod 19 to rotate at the same time. The rotation of the movable rod 19 drives the first reflector 21 to deflect with the movable rod 19 as the axis. , the first reflector 21 is deflected to the outside of the light-through groove 17. When the first reflector 21 is deflected, the third rotating rod 28 is tilted from the vertical state due to the deflection of the first reflector 21. At this time, the third rotating rod 28 moves along the sliding groove 3 27. The third rotating rod 28 can move the second reflector 26 from the sliding groove 25 to the outside of the sliding groove 25. When the second reflector 26 moves inside the sliding groove 25, the second reflector 26 does not contact the first switch 23, and the alarm 22 sounds. The alarm sound reverberates inside the sliding groove 25 and then diffuses the alarm sound through multiple sound-through grooves 24, so that people can better hear the alarm sound. The second reflector 26 is affected by the length of the third rotating rod 28. Due to the limitation, a part of the second reflector 26 remains in the second sliding groove 25 to support the second reflector 26, and the second tooth plate 16 is separated from the half gear 20 and no longer meshes. At the same time, the first reflector 21 deflects to 100° and stops deflecting. The first reflector 21 and the second reflector 26 are unfolded to increase the light area reflected by the emergency light 6 when it is illuminated, and the second reflector 26 is green in color, making the light more conspicuous and the position of the light can be found more quickly. When the emergency light 6 illuminates the concave groove 32, the light is refracted on the surfaces of multiple concave grooves 32 to increase the diffusion area of ​​the light. People evacuate according to the light and sound. When the power is restored, the electric telescopic rod 3 drives the LED light board 4 to rise and drives the above-mentioned components to reset in sequence.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
