Technical Field

[0001] This utility model relates to the field of laboratory safety monitoring technology, and in particular to a laboratory gas leak linkage alarm control device. Background Technology

[0002] Chemical reactions often produce many harmful gases, such as hydrogen, carbon monoxide, carbon dioxide, methane, and toluene. These gases are harmful to the human body, being toxic or flammable and explosive. In chemical laboratories, leaks of these toxic, harmful, flammable, and explosive gases can endanger the safety of laboratory personnel. Therefore, early detection, early warning, and timely and appropriate resolution of leaks are crucial to ensuring laboratory safety to the greatest extent possible. This is why alarm control devices are used.

[0003] The control devices of existing gas alarms are all fixed to the control box or wall and cannot be disassembled. Once maintenance is required, they cannot be removed as a whole, making disassembly and assembly quite inconvenient.

[0004] Therefore, it is necessary to provide a new laboratory gas leak linkage alarm control device to solve the above-mentioned technical problems. Summary of the Invention

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 4 A laboratory gas leak linkage alarm control device includes a control device body 1. A mounting plate 2 is installed on the rear surface of the control device body 1. A fixing plate 3 is provided on the rear side of the mounting plate 2. A symmetrically distributed splitting mechanism 4 is provided at the connection between the mounting plate 2 and the fixing plate 3. A fixing mechanism 6 is provided at the connection between the splitting mechanism 4 and the mounting plate 2. A working cavity 7 is formed inside the mounting plate 2. A linkage mechanism 8 is housed inside the working cavity 7. An adjusting mechanism 9 is provided at the intersection of the linkage mechanism 8 and the fixing mechanism 6. A rotating mechanism 5 is provided at the driving end of the linkage mechanism 8.

[0022] In use, when disassembling and assembling the control device body 1, firstly, the rotating motor 51 is started, causing the rotating shaft 52 to rotate. This causes the first bevel gear 81, mounted on the outer wall of the end of the rotating shaft 52, to rotate synchronously. Consequently, the two second bevel gears 82, symmetrically meshed on the upper and lower sides of the first bevel gear 81, rotate in opposite directions. At this time, the two adjusting screws 91, each connected to one of the two second bevel gears 82, also rotate synchronously in the same direction. This causes the two adjusting nuts 92, respectively fitted onto the outer walls of the two adjusting screws 91, to move vertically back and forth on the outer walls of the two adjusting screws 91 as they rotate. This causes the two adjusting nuts 92 to move closer or further apart, resulting in the two adjusting sliders 94, each mounted on one side of the adjusting nuts 92, moving... The two sets of adjusting slides 93 move synchronously inside each other, causing the two fixing blocks 62 installed on one side of the two adjusting sliders 94 to move synchronously as well. When the two fixing blocks 62 move out of the two sets of fixing slots 61, the fixed connection between the control device body 1 and the fixing plate 3 will be opened. The control device body 1 can be disassembled from the fixing plate 3 by sliding left and right between the disassembly slide 41 and the disassembly slide bar 42. Conversely, when the fixing blocks 62 are engaged inside the fixing slots 61, the control device body 1 and the fixing plate 3 will be in a fixed connection state. This enables convenient and quick disassembly and installation of the control device body 1, which not only ensures the maintenance work of the control device body 1 by the staff, but also facilitates the disassembly and assembly work of the control device body 1.

[0023] In the specific implementation process, such as Figure 1 and Figure 3 As shown, the splitting mechanism 4 includes splitting grooves 41 symmetrically opened on the rear outer wall of the mounting plate 2. A splitting slide bar 42 is slidably arranged inside the splitting groove 41. The side of the splitting slide bar 42 away from the splitting groove 41 is connected to the fixing plate 3.

[0024] During use, the sliding engagement between the splitting slide bar 42 and the splitting slide groove 41 ensures that the control device body 1 is positioned more accurately and is easier to install.

[0025] refer to Figure 1 and Figure 3 As shown, the rotating mechanism 5 includes a rotating motor 51 mounted on the outer wall of one side of the mounting plate 2. The driving end of the rotating motor 51 is fixed with a rotating shaft 52. The end of the rotating shaft 52 away from the rotating motor 51 extends rotatably into the interior of the working cavity 7 and is connected to a bearing on one side of the inner wall of the working cavity 7 at its end.

[0026] In use, the rotating shaft 52 is installed on the drive end of the rotating motor 51. When the rotating motor 51 is running, the rotating shaft 52 can rotate in both directions inside the working cavity 7, in preparation for adjusting the position of the fixing mechanism 6 later.

[0027] refer to Figure 3 As shown, the linkage mechanism 8 includes a first bevel gear 81 fixedly sleeved on the outer wall of the end of the rotating shaft 52, and the first bevel gear 81 is located inside the working cavity 7.

[0028] In use, the first bevel gear 81 is installed on the outer wall of the rotating shaft 52. When the rotating shaft 52 rotates, the first bevel gear 81 will also rotate synchronously.

[0029] refer to Figure 3 As shown, the first bevel gear 81 is meshed with the second bevel gear 82 on both its upper and lower sides, and both second bevel gears 82 are located inside the working cavity 7.

[0030] In use, the two second bevel gears 82 are respectively meshed on the upper and lower sides of the first bevel gear 81. When the first bevel gear 81 rotates with the rotating shaft 52, the two second bevel gears 82 will also rotate synchronously in opposite directions.

[0031] refer to Figure 3 As shown, the adjustment mechanism 9 includes an adjustment screw 91 fixedly inserted through the inner surface of the second bevel gear 82, and the outer wall of the end of the adjustment screw 91 away from the second bevel gear 82 is connected to the inner wall of one side of the working cavity 7 by a bearing.

[0032] In use, the adjusting screw 91 is connected to the second bevel gear 82. When the second bevel gear 82 rotates with the first bevel gear 81, the adjusting screw 91 will also rotate synchronously.

[0033] refer to Figure 3 As shown, an adjusting nut 92 is threaded onto the outer surface of the adjusting screw 91, and the adjusting nut 92 is located inside the working cavity 7.

[0034] When in use, the adjusting nut 92 is threaded onto the outer wall of the adjusting screw 91. When the adjusting screw 91 rotates, the adjusting nut 92 will move vertically on the outer wall of the adjusting screw 91.

[0035] refer to Figure 3 As shown, the adjustment mechanism 9 also includes an adjustment groove 93 formed on the inner wall of one side of the working chamber 7. An adjustment slider 94 is movably disposed inside the adjustment groove 93. One end of the adjustment slider 94 inside the working chamber 7 is connected to the adjustment nut 92.

[0036] In use, the adjusting slider 94 is connected to the adjusting nut 92. When the adjusting nut 92 moves vertically with the rotation of the adjusting screw 91, the adjusting slider 94 will also move synchronously inside the adjusting groove 93.

[0037] refer to Figure 3 and Figure 4 As shown, the fixing mechanism 6 includes a fixing slot 61 formed on the outer wall of one side of the splitting slide 41. A fixing block 62 is engaged inside the fixing slot 61. The end of the fixing block 62 away from the fixing slot 61 is connected to the adjusting slider 94.

[0038] In use, the fixing block 62 is connected to the adjusting slider 94. When the adjusting slider 94 moves with the adjusting slide 93, the fixing block 62 will also move synchronously inside the fixing slot 61. When the fixing block 62 moves out of the fixing slot 61, the control device body 1 can be removed from the fixing plate 3 through the sliding engagement between the splitting slide bar 42 and the splitting slide 41. Conversely, when the fixing block 62 is engaged inside the fixing slot 61, the control device body 1 will be securely installed on the fixing plate 3.

[0039] The working principle of the laboratory gas leak linkage alarm control device provided by this utility model is as follows: When disassembling and assembling the control device body 1, the rotating motor 51 is first started, so that the rotating shaft 52 can rotate. The first bevel gear 81 installed on the outer wall of the end of the rotating shaft 52 will also rotate synchronously. This causes the two second bevel gears 82 symmetrically meshed on the upper and lower sides of the first bevel gear 81 to rotate in opposite directions. At this time, the two adjusting screws 91 connected to the two second bevel gears 82 will also rotate synchronously in the same direction. This causes the two adjusting nuts 92, which are respectively sleeved on the outer walls of the two adjusting screws 91, to move back and forth vertically on the outer walls of the two adjusting screws 91 as the two adjusting screws 91 rotate. This causes the two adjusting nuts 92 to move closer or further apart from each other, so that the two adjusting nuts installed on the two adjusting nuts... The two adjusting sliders 94 on one side of 92 will move synchronously inside the two sets of adjusting slide grooves 93, so that the two fixing blocks 62 installed on one side of the two adjusting sliders 94 will also move synchronously. When the two fixing blocks 62 move out of the two sets of fixing slots 61, the fixed connection between the control device body 1 and the fixing plate 3 will be opened. The control device body 1 can be disassembled from the fixing plate 3 by sliding left and right between the split slide groove 41 and the split slide bar 42. Conversely, when the fixing blocks 62 are engaged inside the fixing slots 61, the control device body 1 and the fixing plate 3 will be in a fixed connection state. This enables convenient and quick disassembly and installation of the control device body 1, which not only ensures the maintenance work of the control device body 1, but also facilitates the disassembly and assembly work of the control device body 1.
