[0002] An alarm is an electronic product that uses sound, light, air pressure, etc. to remind or warn us that we should take certain actions in order to prevent or prevent the consequences of an event. Alarms are divided into mechanical alarms and electronic alarms. With the advancement of technology, mechanical alarms are increasingly replaced by advanced electronic alarms and are often used in system failures, security precautions, transportation, medical rescue, emergency rescue, induction detection and other fields. Alarms are prone to explosion during use. Most of the existing alarms have low explosion-proof strength during use and are easily damaged under high impact conditions, making them unable to work, affecting their use. They do not have sufficient protection and have poor safety performance. Moreover, the protective cover cannot be replaced alone after being damaged and needs to be replaced together with the alarm body, and the replacement cost is high. Utility Model Content

[0023] Furthermore, a slide groove 10 is provided on the surface of the connecting plate 4 and runs through the surface. A second slide bar 12 is fixedly connected inside the slide groove 10 . A movable plate 11 is slidably connected outside the second slide bar 12 . The movable plate 11 moves along the second slide bar 12 .

[0024] Furthermore, a second spring 13 is fixedly connected between the bottom of the movable plate 11 and the slide groove 10. The protective cover 5 moves with the movable plate 11 along the second slide rod 12. The movable plate 11 moves in the direction of the second spring 13 to squeeze the second spring 13. The second spring 13 is squeezed to generate elastic force, which further buffers the impact force.

[0025] Furthermore, clamping holes 15 are provided on both sides of the connecting plate 4 , and a clamping block 16 is slidably connected inside the fixing seat 2 . The clamping block 16 enters into the clamping hole 15 to limit the position of the connecting plate 4 .

[0026] Furthermore, a third sliding rod 18 is fixedly connected to the interior of the fixing seat 2 , and a limiting plate 19 is slidably connected to the outer side of the third sliding rod 18 , and the limiting plate 19 moves along the third sliding rod 18 .

[0027] Furthermore, one end of the limiting plate 19 away from the third sliding rod 18 is fixedly connected to the clamping block 16 , and the clamping block 16 moves with the limiting plate 19 .

[0028] Furthermore, a third spring 17 is fixedly connected between one side of the limit plate 19 and the fixed seat 2. The block 16 is squeezed and moves with the limit plate 19 along the third slide rod 18 in the direction of the third spring 17. The third spring 17 is squeezed to generate elastic force. When the hole 15 moves to one end of the block 16, the third spring 17 loses its pressing force. Under the action of the elastic force, the third spring 17 pushes the limit plate 19 to move. The limit plate 19 moves with the block 16, so that the block 16 enters the hole 15 to limit the position of the connecting plate 4.

[0029] Furthermore, one end of the clamping block 16 away from the clamping hole 15 passes through one side of the fixing seat 2 and is fixedly connected to a fixing plate 20 , and the fixing plate 20 moves with the clamping block 16 .

[0030] Furthermore, the fixing plate 20 is detachably connected to the fixing seat 2 via the first bolt 21 to prevent the fixing plate 20 from moving during use.

[0031] Furthermore, the two ends of the base 1 are detachably connected with a second bolt 22, so that the alarm can be better installed on an object or wall. A plurality of sound outlets are provided on the outside of the protective cover 5. The protective cover 5 is made of transparent material, so that people can better see the warning light, and the sound outlets can better allow people to hear the warning sound of the alarm.

[0032] Specifically, when using the utility model, the base 1 is first installed on an object or wall through the second bolt 22, and the bottom of the connecting plate 4 is inserted into the fixing seat 2. When the connecting plate 4 enters the fixing seat 2, the block 16 is squeezed. The block 16 is squeezed and moves with the limiting plate 19 along the third slide bar 18 toward the direction of the third spring 17. The third spring 17 is squeezed and generates elastic force. When the clamping hole 15 moves to one end of the block 16, the third spring 17 loses its pressing force. Under the action of the elastic force, the third spring 17 pushes the limiting plate 19 to move. The limiting plate 19 moves with the block 16, so that the block 16 enters the clamping hole 15 to limit the position of the connecting plate 4, and the first bolt 21 is rotated to connect the fixing plate 20 with the fixing seat 2 to prevent the fixing plate 20 from moving with the block 16 out of the clamping hole 15 during use to loosen the restriction on the connecting plate 4. When the protective cover 5 is hit, the protective cover 5 moves in the direction of the damper 14, and the damper 14 buffers the impact force. The protective cover 5 moves with the moving plate 11 along the second sliding rod 12, and the moving plate 11 moves in the direction of the second spring 13 to squeeze the second spring 13. The second spring 13 is squeezed and generates elastic force to further buffer the impact force. When the protective cover 5 is impacted from the left and right, the fixed seat 2 squeezes the first spring 9 along the first sliding rod 8, and the first spring 9 generates elastic force to apply thrust to one side of the fixed seat 2, thereby reducing the impact force on the protective cover 5 and protecting the alarm body 3 in the protective cover 5. When a fire occurs, the lamp body on the alarm body 3 lights up and radiates from the protective cover 5. The alarm body 3 emits a sound that radiates from the sound outlet on the surface of the protective cover 5 to remind people who have not seen the light.
