[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figure 1-3The explosion-proof sound and light alarm lamp shown in the figure is easy to disassemble and assemble, including a connecting plate 1, a base 6, an alarm light 7 and an alarm 8. The alarm light 7 and the alarm 8 can emit light and sound to remind people around. A fixed plate 2 is fixedly connected to one side of the connecting plate 1. A dust cover 3 is fixedly connected to the upper end of the fixed plate 2. The dust cover 3 can reduce the direct contact between the steel cable 5 on the winding roller 4 and dust. A driving motor is fixedly connected to one side of the dust cover 3. The output end of the driving motor is fixedly connected to the winding roller 4. The driving motor can drive the winding roller 4 to rotate to realize the reeling and unreeling of the steel cable 5. The winding roller 4 is sleeved with a steel cable 5. The steel cable 5 is fixedly connected to the base 6 at the bottom end, and the bottom end of the base 6 is fixedly connected to the alarm light 7. The two sides away from each other in the dust cover 3 are fixedly connected to the limit rod 9, and the limit rod 9 is sleeved with a guide block 10. The two guide blocks 10 are in contact with a spring 11 on the side away from each other. The spring 11 is used to drive the guide blocks 10 to move relative to each other, so that the steel cable 5 is evenly distributed on the winding roller 4. The spring 11 is sleeved on the limit rod 9, and the two ends of the spring 11 contact the guide block 10 and the dust cover 3 respectively. The upper end of the fixed plate 2 is fixedly connected to the card plate 13, and the card wheel 14 is rotatably connected in the card plate 13, and the card wheel 14 is in contact with the steel cable 5.

[0018] The dust cover 3 contacts the supporting ball 12 , and the supporting ball 12 is rotatably embedded in one side of the guide block 10 . The friction between the dust cover 3 and the guide block 10 is reduced by providing the supporting ball 12 .

[0019] A synchronization rod 17 is provided on the bottom side of the winding roller 4 , and the synchronization rod 17 is fixedly connected between the two guide blocks 10 . By providing the synchronization rod 17 , the two relative guide blocks 10 can move synchronously.

[0020] Among them, the buffer sheet 15 is fixedly connected to the upper side of the base 6, and the buffer sheet 15 contacts the bottom side of the steel cable 5. The buffer sheet 15 is made of rubber material. By providing the buffer sheet 15, the collision between the base 6 and the fixed plate 2 is reduced.

[0021] A card slot 16 is provided on the bottom side of the fixing plate 2 , and the card slot 16 contacts the buffer sheet 15 . By providing the card slot 16 , part of the base 6 is adapted to contact the card slot 16 , thereby increasing the stability of the base 6 .

[0022] Working principle: When the alarm light 7 and alarm 8 need to be maintained, the drive motor (drive motor Bluetooth connection controller) can be started to drive the winding roller 4 to rotate, and the steel cable 5 is unwound and moved downward. Under gravity conditions, the base 6 moves downward, and the alarm light 7 and alarm 8 move downward, so as to facilitate maintenance. When the maintenance is completed, the rotation of the winding roller 4 can be used to shrink the steel cable 5, and promote the base 6, alarm light 7 and alarm 8 to move upward, and then the base 6 gradually enters the card slot 16, and the buffer sheet 15 fits the card slot 16, and then part of the base 6 fits the card slot 16, so as to maintain the stability of the alarm light 7 and alarm 8.
