The storage battery 8 is a small lead-acid battery and is used for storing electricity for the warning device. A quick-disassembly component is arranged on the right side inside the housing 1, and the quick-disassembly component is used for disassembling and replacing the storage battery 8. A plurality of evenly distributed first tenons 6 are slidably connected to the upper part of the housing 1. The first tenons 6 are made of aluminum alloy material and are used for fixing the warning light 2. The adjacent sides of the plurality of first tenons 6 abut against the lower part of the warning light 2. A first gear 13 is rotatably connected inside the housing 1. The first gear 13 is made of stainless steel material and is used for driving other components inside the warning device. The top of the first gear 13 meshes with the bottom of the first tenon 6. When the first gear 13 rotates, it can drive a plurality of first tenons 6 to move. A plurality of evenly distributed second gears 14 are rotatably connected to the lower side inside the housing 1. The second gears 14 are used for driving the first gear 13 to rotate. The second gears 14 are made of stainless steel material, and the second gears 14 mesh with the bottom of the first gear 13. An internal hexagonal groove 9 is opened at one end of one of the second gears 14, and the internal hexagonal groove 9 is used for driving the component to operate with a hexagonal wrench. A first slot 5 is opened at the lower part of the warning light 2, and the first slot 5 is used for enhancing the connection stability between the warning light 2 and the plurality of first tenons 6. The adjacent sides of the plurality of first tenons 6 abut against the inside of the first slot 5. A lamp cover 4 is sleeved on the outer periphery of the warning light 2. The lamp cover 4 is made of aluminum alloy material and is used for protecting the warning light 2 to prevent it from being damaged by collision. A plurality of evenly distributed sliding grooves 15 are opened at the upper part of the housing 1. The first tenons 6 slide inside the sliding grooves 15. The sliding grooves 15 are used for guiding the sliding track of the first tenons 6 and preventing them from shaking, so as to firmly fix the warning light 2. A first positioning groove 10 is opened inside the housing 1. The first gear 13 rotates inside the first positioning groove 10. The first positioning groove 10 is used for limiting the movement range of the first gear 13 and enabling it to operate stably inside the warning device. A plurality of evenly distributed second positioning grooves 11 are opened at the lower side inside the housing 1. Two positioning rods 12 are installed inside the second positioning grooves 11.

The upper part of the spring 17 abuts against the bottom of the button 7. A battery compartment 18 is opened on the right side of the housing 1, which is used to place and fix the storage battery 8. The storage battery 8 abuts against the inside of the battery compartment 18. On both the front and rear sides of the storage battery 8, there are second slots 20. The second tenons 19 abut against the inside of the second slots 20. The second slots 20 are used to allow the second tenons 19 to insert into the storage battery 8 to fix it. When the storage battery 8 fails or runs out of power, the quick-disassembly component can enable maintenance personnel to quickly replace the storage battery 8, ensuring that the fire alarm sound and light warning device will not stop working due to problems with the storage battery 8, and ensuring that effective warning signals can always be emitted in case of an emergency, providing key time guarantee for personnel evacuation and fire rescue.

[0033] Working principle: When the warning light 2 needs to be installed, first place the warning light 2 on the upper part of the housing 1. Insert a hexagonal wrench into the internal hexagonal groove 9 and rotate the hexagonal wrench to drive the second gear 14 to rotate. The second gear 14 cooperates with the other two second gears 14 to drive the first gear 13 to rotate. The first gear 13 can drive a plurality of first tenons 6 to slide on the upper part of the housing 1 through the spiral tooth grooves opened on its upper side, so that the adjacent sides of the plurality of first tenons 6 abut against the inside of the first slot 5 opened on the lower part of the warning light 2, thus completing the quick installation of the warning light 2.

[0034] After the warning light 2 is installed, if the storage battery 8 needs to be disassembled and replaced, press the button 7 to make its bottom squeeze the two springs 17, which can make the button 7 slide on the outer periphery of the two slide rods 16. The button 7 can drive the two second tenons 19 to descend, so that they no longer lock the second slot 20 inside the storage battery 8, thus releasing the fixation of the storage battery 8 and enabling the replacement of the storage battery 8.
