[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 An emergency alarm device with a foolproof structure includes a base shell 1, and further includes: a linkage triggering mechanism 2, a protective mechanism 3, and a fixing mechanism 4. The linkage triggering mechanism 2 is mounted on the base shell 1, the protective mechanism 3 is mounted on the linkage triggering mechanism 2, and the fixing mechanism 4 is mounted on the rear side of the base shell 1. The linkage triggering mechanism 2 includes: an upper shell 21, an irregularly shaped shell 22, a rotating rod 23, a first sliding rod 24, a first spring 25, and a baffle 26. The upper shell 21 is fixedly mounted on the upper side of the base shell 1, and rectangular slots are provided on both the upper and lower sides of the upper shell 21. 27. The irregular shell 22 is fixedly installed on the upper side of the upper shell 21. The middle side of the rotating rod 23 is rotatably connected to the irregular shell 22 through a rotating shaft. The first sliding rod 24 is slidably connected to the left side of the irregular shell 22. The first spring 25 is disposed on the first sliding rod 24. One end of the first spring 25 is fixedly installed on the front side of the first sliding rod 24, and the other end of the first spring 25 is in close contact with the irregular shell 22. The baffle 26 is fixedly installed on the upper shell 21. The linkage triggering mechanism 2 further includes a triggering component, which is installed on the irregular shell 22.

[0031] The protective mechanism 3 is used to prevent accidental activation. When the protective mechanism 3 is activated, it triggers the linkage mechanism 2. After the linkage mechanism 2 is activated, it unlocks some components of the protective mechanism 3, enabling some components in the protective mechanism 3 to trigger an emergency alarm. The fixing mechanism 4 allows the device to be quickly installed on the metal frame without drilling.

[0032] The rotation of the rotating rod 23 of the linkage triggering mechanism 2 causes the rotating rod 23 to leave the position of the first sliding rod 24, and is restored by the first spring 25 which is in a compressed state, thus driving the first sliding rod 24 to move forward.

[0033] The triggering component includes: a moving block 28, a first fixed rod 29, a second sliding rod 210, and a second spring 211. The front side of the moving block 28 is slidably connected to the right side of the rectangular slot 27 on the lower side of the upper shell 21. The moving block 28 has multiple strip-shaped openings 212. The front side of the moving block 28 is provided with a slope 213. Each strip-shaped opening 212 is provided with a first fixed rod 29. The first fixed rod 29 is fixedly installed on the irregular shell 22. The second sliding rod 210 is slidably connected to the right side of the irregular shell 22. The second spring 211 is provided on the second sliding rod 210. One end of the second spring 211 is fixedly installed on the front side of the second sliding rod 210, and the other end of the second spring 211 is in close contact with the irregular shell 22.

[0034] The triggering component further includes a pressing component, which is mounted on the baffle 26. The pressing component includes a fixed base 214, a third sliding rod 215, a third spring 216, and a pressing switch 217. The fixed base 214 is fixedly mounted on the upper side of the baffle 26. The third sliding rod 215 is slidably connected to the fixed base 214. A circular opening 218 is provided on the side wall of the third sliding rod 215. The rear side of the first sliding rod 24 is disposed in the circular opening 218. The third spring 216 is disposed on the third sliding rod 215. One end of the third spring 216 is fixedly connected to the lower side of the fixed base 214, and the other end of the third spring 216 is fixedly connected to the middle side of the third sliding rod 215. The pressing switch 217 is fixedly mounted on the upper shell 21 and is located directly below the third sliding rod 215.

[0035] The moving block 28 of the trigger component moves backward, causing the rotating rod 23 to rotate. The rotation of the rotating rod 23 causes it to leave the position of the first sliding rod 24 and be restored by the first spring 25, which was in a compressed state. This causes the first sliding rod 24 to move forward. The rotation of the rotating rod 23 causes the second sliding rod 210 to move backward. The backward movement of the second sliding rod 210 causes the second spring 211 to undergo elastic deformation and be compressed. The moving block 28 is released, and the second spring 211, which has undergone elastic deformation and been compressed, restores and pushes the second sliding rod 210 back to its initial position. The second sliding rod 210 moves to its initial position, causing the rotating rod 23 to rotate to its initial position. The irregular shell 22 limits the rotation of the rotating rod 23 to its initial position.

[0036] Example 2: In some embodiments, such as Figures 1-8 In a preferred embodiment of the present invention, the protective mechanism 3 includes: a limiting strip 31, a sliding frame 32, and a gas spring 33. The limiting strip 31 is slidably connected to the rectangular slot 27 of the upper shell 21. The sliding frame 32 is fixedly installed at one end of the limiting strip 31 away from the rectangular slot 27. One end of the gas spring 33 is fixedly installed on the upper shell 21, and the other end of the gas spring 33 is fixedly installed on the sliding frame 32.

[0037] Moving the sliding frame 32 to the right causes the gas spring 33 to undergo elastic deformation and be compressed. The movement of the sliding frame 32 to the right drives the limiting strip 31 to move to the right. The limiting strip 31 moves to the rightmost side of the rectangular slot 27 and contacts the inclined surface 213 on the front side of the moving block 28, causing the moving block 28 to move backward. The backward movement of the moving block 28 drives the rotating rod 23 to rotate. The rotation of the rotating rod 23 causes the rotating rod 23 to leave the position of the first sliding rod 24 and be restored by the first spring 25, which was in a compressed state. This causes the first sliding rod 24 to move forward. The first sliding rod 24 moves forward and leaves the position of the circular opening 218 of the third sliding rod 215. At this time, the third sliding rod 215 is unlocked, allowing it to be pressed and moved up and down. Releasing the sliding frame 32 causes the elastically deformed gas spring 33 to restore and push the sliding frame 32 back to its initial position.

[0038] The protective mechanism 3 further includes a reminder component, which is mounted on the bottom shell 1.

[0039] The reminder component includes a controller 34 and a first buzzer 35. The controller 34 is fixedly installed inside the bottom shell 1, and the first buzzer 35 is fixedly installed on the right side of the bottom shell 1. The first buzzer 35 is electrically connected to the controller 34. The controller 34 can be set as an AI-7xx8 series economical multi-loop measurement and control instrument two-in-one controller produced by Xiamen Yudian Automation Technology Co., Ltd.

[0040] The reminder component also includes an audio-visual component, which is installed on the left side of the bottom shell 1. The audio-visual component includes a connecting wire 36, a fixing shell 37, a second buzzer 38, and an LED bead 39. One end of the connecting wire 36 is electrically connected to the controller 34, and the other end of the connecting wire 36 is fixedly installed on the fixing shell 37. The second buzzer 38 is fixedly installed on the front side of the fixing shell 37, and the LED bead 39 is fixedly installed on the lower side of the fixing shell 37. Both the second buzzer 38 and the LED bead 39 are electrically connected to the connecting wire 36.

[0041] Pressing down the third sliding lever 215 causes it to move downward, pressing the push switch 217. The electrical signal from the push switch 217 is transmitted to the controller 34, which is connected to an external power source. The controller 34 controls the first buzzer 35, the second buzzer 38, and the LED beads 39 to activate, providing sound and light alerts. Multiple sound and light components can be distributed and installed at the locations where alarm alerts are needed to increase the alarm range.

[0042] The fixing mechanism 4 includes: a fixing frame 41, a second fixing rod 42, a support plate 43, a sliding plate 44, and a screw 45. The fixing frame 41 is fixedly installed on the rear side of the upper shell 21. The two second fixing rods 42 are fixedly installed inside the fixing frame 41. The support plate 43 is fixedly installed on the right side of the fixing frame 41. The sliding plate 44 is slidably connected to the second fixing rod 42. The two ends of the screw 45 are rotatably connected to the middle side of the fixing frame 41, and the middle side of the screw 45 is threadedly connected to the middle side of the sliding plate 44.

[0043] Rotating the screw 45 causes the sliding plate 44 to move left and right on the second fixed rod 42. The sliding plate 44 and the support plate 43 work together to clamp the equipment onto the steel frame or column, achieving quick installation without drilling.

[0044] The protection mechanism 3 uses a limit bar 31 and a sliding frame 32 to prevent accidental activation. The sliding frame 32 needs to be moved to the rightmost trigger block 28 so that the push switch 217 is unlocked. Only then can the push switch 217 be triggered by the third sliding rod 215 to activate the first buzzer 35, the second buzzer 38, and the LED bead 39 to complete the alarm. While the sliding frame 32 prevents accidental activation, it also needs to cooperate with the linkage triggering mechanism 2 to trigger the alarm. The alarm device achieves its foolproof effect through the cooperation of the sliding frame 32, the limit bar 31, and the linkage triggering mechanism 2.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
