[0022] The following further details the present utility model:

[0023] As Figures 1 to 5 Shown, the present utility model provides an alarm device for chemical safety management, including a fixed plate 1 and an alarm 4. The bottom of the fixed plate 1 is fixedly connected with a fixed component 2. The fixed component 2 includes an inner connecting cylinder 21. The inner side of the inner connecting cylinder 21 is equidistantly provided with limit card slots 23. The bottom of the inner connecting cylinder 21 is provided with a limit boss 24 adapted to the limit card slots 23. The inner part of the inner connecting cylinder 21 is movably clamped with a docking housing 3. The docking housing 3 includes an outer shell 31. The outer side of the outer shell 31 is fixedly connected with a limit card block 33. The limit card block 33 is movably clamped inside the limit card slots 23. The alarm 4 is fixedly installed inside the outer shell 31. The outside of the fixed plate 1 is movably installed with an outer protection frame 6 located outside the outer shell 31.

[0024] By inserting the outer shell 31 from the inner connecting cylinder 21 so that the limit card block 33 is inserted into the position of the bottom opening of the limit card slots 23, the card column 27 is pushed into the mounting hole 25 by the outer shell 31. The outer shell 31 is rotated towards the side of the limit boss 24, so that the limit card block 33 is clamped inside the limit boss 24, and the card column 27 slides along the ring groove 34 to the fixed groove 35. The card column 27 is pushed by the elastic force of the spring 26 and clamped into the inside of the fixed groove 35. The outer shell 31 is limited and fixed by the cooperation of the card column 27 and the limit boss 24. Thus, screws are not needed during disassembly and assembly, which is convenient for disassembly, assembly and maintenance work. At the same time, through the connecting ring 61, it is fixedly installed outside the docking housing 3 by using the internal thread 62 to cooperate with the external thread 28, and protection is provided by the protection rib 63. At the same time, it is convenient for disassembly and assembly, ensuring the disassembly and assembly convenience of the docking housing 3.

[0025] As Figure 3 Shown, the top surface inside the inner connecting cylinder 21 is provided with a mounting hole 25. The inside of the mounting hole 25 is movably clamped with a spring 26 and a card column 27 located below the spring 26. The top of the outer shell 31 is provided with a ring groove 34. The inside of the ring groove 34 is provided with a fixed groove 35 corresponding to the card column 27. The card column 27 is movably clamped inside the fixed groove 35.

[0026] By rotating the outer shell 31 counterclockwise toward the side of the limit boss 24, the clamping post 27 slides along the annular groove 34 to the fixing groove 35. The clamping post 27 is pushed by the elastic force of the spring 26 and snaps into the inside of the fixing groove 35. Thus, while providing a limit to the outer shell 31 through the clamping post 27, the elastic force of the spring 26 makes the limit clamping block 33 abut against the inner side of the limit boss 24 to ensure stable fixation.

[0027] As Figure 4 shown, a limit ring 32 is fixedly connected to the outside of the outer shell 31 below the limit clamping block 33, and the limit ring 32 fits against the bottom surface of the inner connecting cylinder 21.

[0028] Through the setting of the limit ring 32, after the outer shell 31 is docked and installed with the inner connecting cylinder 21, it fits against the bottom surface of the inner connecting cylinder 21 to ensure proper installation.

[0029] As Figure 4 shown, a bottom shell 36 is threadedly connected below the outer shell 31, and both the outer shell 31 and the bottom shell 36 are made of transparent materials.

[0030] By threadedly connecting the bottom shell 36 below the outer shell 31, it is convenient to disassemble for maintaining the alarm 4. Since both the outer shell 31 and the bottom shell 36 are made of transparent materials, it is convenient for the alarm 4 to transmit light for alarming.

[0031] As Figure 3 and Figure 4 shown, the bottom of the clamping post 27 is arc-shaped.

[0032] The lengths of both the limit clamping block 33 and the limit boss 24 are half of the length of the limit clamping groove 23.

[0033] After the clamping post 27 with an arc-shaped bottom snaps into the fixing groove 35, when a force is applied to rotate the outer shell 31, the clamping post 27 can be pushed upward, thus facilitating disassembly. Since both the limit clamping block 33 and the limit boss 24 are half of the length of the limit clamping groove 23, the limit clamping block 33 can snap into the limit clamping groove 23 and is limited by the limit boss 24 to ensure stable installation.

[0034] As Figure 5 shown, the bottom of the fixing plate 1 is fixedly connected with an outer connecting cylinder 22. The outer connecting cylinder 22 is arranged outside the inner connecting cylinder 21, and an external thread 28 is provided on the outside of the outer connecting cylinder 22.

[0035] The outer protection frame 6 includes a connecting ring 61. An internal thread 62 adapted to the external thread 28 is provided on the inner side of the connecting ring 61. The connecting ring 61 is threadedly installed on the outside of the outer connecting cylinder 22, and a protective rib 63 is fixedly connected to the bottom of the connecting ring 61.

[0036] After installing the docking housing 3, the protective rib 63 is sleeved outside the docking housing 3, and by rotating the connecting ring 61, the internal thread 62 is screwed and docked with the external thread 28 to fix the protective rib 63 outside the docking housing 3, providing protection while facilitating disassembly and ensuring the convenience of disassembling the docking housing 3.

[0037] Next, the working principle of the alarm device for chemical safety management will be specifically described.

[0038] As Figures 1 to 5 shown, the fixing plate 1 is fixed at the installation position by screws. The housing 31 with the alarm 4 installed inside is inserted into the limit card slot 23 from the inner connecting cylinder 21, and the limit card block 33 is aligned with the bottom opening of the limit card slot 23. At this time, the clamping post 27 protruding from the installation hole 25 is located in the annular groove 34 at the top of the housing 31 and is pushed into the installation hole 25. Subsequently, the housing 31 is rotated counterclockwise along the side facing the limit boss 24, so that the limit card block 33 is stuck inside the limit boss 24, and the clamping post 27 slides along the annular groove 34 to the fixing groove 35, and the clamping post 27 is pushed by the elastic force of the spring 26 to be stuck inside the fixing groove 35. The housing 31 is limited and fixed by the cooperation of the clamping post 27 and the limit boss 24. During disassembly, the housing 31 is rotated clockwise. Due to the large rotational force applied and the arc-shaped bottom of the clamping post 27, when the housing 31 rotates, it pushes the clamping post 27 to extrude the spring 26 and move out of the fixing groove 35, thereby disassembling the housing 31, which facilitates the disassembly and maintenance of the docking housing 3. After installing the docking housing 3, the protective rib 63 is sleeved outside the docking housing 3, and by rotating the connecting ring 61, the internal thread 62 is screwed and docked with the external thread 28 to fix the protective rib 63 outside the docking housing 3, providing protection while facilitating disassembly and ensuring the convenience of disassembling the docking housing 3.

[0039] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
