Since the vent pipe is fixedly mounted on the mounting base plate, and the mounting base plate also integrates the alarm, toxic gas analyzer, and battery into a single unit, it is convenient to carry and use as a whole, eliminating the need for a separate bracket for the toxic gas detection sensor, and ensuring stable installation.

[0004] However, gas monitoring and alarm devices are often installed in high positions, and the mounting plate is fixed with screws. If they are removed for maintenance, the screws are easily stripped after being corroded over a long period of time, which increases the difficulty of disassembly and assembly. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to improve the prior art represented by the utility model patent CN221573258U, and to provide a toxic gas monitoring and alarm device that is easy to install and disassemble, so as to solve the problems pointed out in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A toxic gas monitoring and alarm device that is easy to assemble and disassemble includes a disassembly mechanism, and a monitoring and alarm mechanism for monitoring toxic gases is provided on the left side of the disassembly mechanism.

[0008] The disassembly mechanism includes a mounting plate with two movable slots inside. A first buckle is slidably disposed in each of the two movable slots. Multiple first springs are fixedly connected to one end of each first buckle. Pull holes are respectively provided at the top and bottom of the mounting plate. A pull rod is slidably inserted into each pull hole. A pull plate is fixedly connected to one end of each pull rod. Two slots are provided on the left side of the mounting plate. A second buckle is inserted into each slot. Each first buckle is adapted to a second buckle.

[0009] Preferably, the end of each pull rod away from the pull plate is fixedly connected to the first buckle, and the end of each first spring away from the first buckle is fixedly connected to the inner wall of the movable groove.

[0010] Preferably, the mounting plate has four mounting holes arranged in a rectangular array.

[0011] Preferably, the monitoring and alarm mechanism includes a housing, a through groove extending from bottom to top through the housing, a pipe installed inside the through groove, an exhaust fan installed at the bottom of the inner wall of the pipe, a disassembly plate slidably inserted into the right side of the housing, a mounting bracket installed on the left side of the disassembly plate, a toxic gas detection sensor installed on the mounting bracket, a controller installed on the left side of the disassembly plate, and an alarm installed on the left side of the mounting bracket.

[0012] Preferably, a detection hole is provided on the right side of the pipe, and the toxic gas detection sensor is plugged into the detection hole.

[0013] Preferably, the right side of the disassembly plate is fixedly connected to two second buckles, and a crossbar is fixedly connected to the right side of the disassembly plate. Both ends of the crossbar are provided with telescopic grooves, and limit blocks are slidably arranged in the telescopic grooves. A second spring is fixedly connected to the end of the two limit blocks that are close to each other. Two sliding grooves are provided on the right side of the crossbar, and sliders are slidably arranged in the two sliding grooves respectively. The left side of each slider is fixedly connected to a limit block.

[0014] Preferably, the front and rear ends of the outer shell are respectively provided with limiting grooves, and the limiting grooves are respectively adapted to the limiting blocks.

[0015] Compared with existing technologies, the advantages of this utility model's conveniently assembled and disassembled toxic gas monitoring and alarm device are:

[0016] First, when disassembling the monitoring and alarm mechanism, simultaneously pull the upper and lower pull plates, causing the pull rod to move the first buckle within the movable slot. This causes the first buckle to compress the first spring, resulting in the spring contracting and separating the first buckle from the second buckle. The left side of the second buckle is fixedly connected to the monitoring and alarm mechanism, allowing the second buckle to be pulled out of the slot for quick removal. Similarly, during installation, pull the upper and lower pull plates to insert the second buckle into the slot. Releasing the pull plates allows the first buckle to engage with the second buckle under the action of the first spring, achieving quick installation. This eliminates the need to tighten screws for disassembly, greatly simplifying the process and improving efficiency.

[0017] Secondly, the pipe is installed in the through groove of the outer shell, and an exhaust fan is installed at the bottom of the inner wall to extract gas for detection. The mounting bracket and the toxic gas detection sensor are installed on the disassembly plate. The toxic gas detection sensor is inserted into the pipe through the detection hole to contact the extracted gas and detect the presence of toxic gas. The controller is installed on the disassembly plate to process the signal from the toxic gas detection sensor and trigger the alarm for warning purposes. The crossbar is connected to the right side of the disassembly plate, and the limiting block slides in the telescopic groove and is provided with elastic force by the second spring. When the disassembly plate is inserted into the outer shell, the limiting block can be locked into the limiting groove of the outer shell under the action of the second spring, which plays a fixing role. When the internal maintenance is performed, the slider is pulled to make the slider slide in the sliding groove, which drives the limiting block to slide in the telescopic groove and squeeze the second spring, so that the limiting block slides out from the limiting groove at both ends of the outer shell, releasing the limiting, and the outer shell can be easily separated from the disassembly plate for internal maintenance.

[0024] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0025] Please see Figure 1-5 A toxic gas monitoring and alarm device that is easy to assemble and disassemble includes a disassembly mechanism, and a monitoring and alarm mechanism for monitoring toxic gases is provided on the left side of the disassembly mechanism.

[0026] The disassembly mechanism includes a mounting plate 1. The mounting plate 1 has two movable slots inside, and a first buckle 2 is slidably disposed in each of the two movable slots. Multiple first springs 3 are fixedly connected to one end of each first buckle 2. Pull holes are opened at the top and bottom of the mounting plate 1, and a pull rod 4 is slidably inserted into each pull hole. A pull plate 5 is fixedly connected to one end of each pull rod 4. Two slots are opened on the left side of the mounting plate 1, and a second buckle 6 is inserted into each slot. Each first buckle 2 is adapted to a second buckle 6.

[0027] The end of each pull rod 4 away from the pull plate 5 is fixedly connected to the first buckle 2, and the end of each first spring 3 away from the first buckle 2 is fixedly connected to the inner wall of the movable groove.

[0028] The mounting plate 1 has four mounting holes arranged in a rectangular array.

[0029] With the above technical solution, the four mounting holes on the mounting plate 1 can be used to install the device in the required position using screws. When disassembling the monitoring and alarm mechanism, the upper and lower pull plates 5 are pulled simultaneously, causing the pull rod 4 to move the first buckle 2 in the movable slot. This causes the first buckle 2 to squeeze the first spring 3, which in turn contracts, separating the first buckle 2 from the second buckle 6. The left side of the second buckle 6 is fixedly connected to the monitoring and alarm mechanism, allowing the second buckle 6 to be pulled out of the slot, achieving a quick removal effect. Similarly, when installing, the upper and lower pull plates 5 are pulled to insert the second buckle 6 into the slot. Releasing the pull plates 5 allows the first buckle 2 to lock onto the second buckle 6 under the action of the first spring 3, achieving a quick installation effect. This eliminates the need to tighten screws for disassembly, greatly simplifying the disassembly and assembly process and improving efficiency.

[0030] Please see Figure 1-5A toxic gas monitoring and alarm device that is easy to install and disassemble includes a housing 7. The housing 7 has a through groove running from bottom to top. A pipe 8 is installed inside the through groove. An exhaust fan 9 is installed at the bottom of the inner wall of the pipe 8. A disassembly plate 10 is slidably inserted into the right side of the housing 7. A mounting bracket 11 is installed on the left side of the disassembly plate 10. A toxic gas detection sensor 12 is installed on the mounting bracket 11. A controller 13 is installed on the left side of the disassembly plate 10. An alarm 14 is installed on the left side of the mounting bracket 11.

[0031] A detection hole is provided on the right side of the pipe 8, and the toxic gas detection sensor 12 is plugged into the detection hole.

[0032] The right side of the disassembly plate 10 is fixedly connected to two second buckles 6. A crossbar 15 is fixedly connected to the right side of the disassembly plate 10. Both the front and rear ends of the crossbar 15 are provided with telescopic grooves. Limit blocks 16 are slidably arranged in the telescopic grooves. A second spring 17 is fixedly connected to the end of the two limit blocks 16 that are close to each other. Two sliding grooves are provided on the right side of the crossbar 15. Sliding blocks 18 are slidably arranged in the two sliding grooves respectively. The left side of each sliding block 18 is fixedly connected to the limit block 16.

[0033] Limiting grooves are provided at the front and rear ends of the outer casing 7, and the limiting grooves are respectively adapted to the limiting blocks 16.

[0034] With the above technical solution, the pipe 8 is installed in the through groove of the outer shell 7, and an exhaust fan 9 is installed at the bottom of the inner wall for extracting gas for detection. The mounting bracket 11 and the toxic gas detection sensor 12 are installed on the disassembly plate 10. The toxic gas detection sensor 12 is inserted into the pipe 8 through the detection hole to contact the extracted gas and detect the presence of toxic gas. The controller 13 is installed on the disassembly plate 10 to process the signal from the toxic gas detection sensor 12 and trigger the alarm 14 to sound an alarm, serving as a warning. The crossbar 15 is connected to the right side of the disassembly plate 10, and the limit block... The limiting block 16 slides within the telescopic groove and is provided with elastic force by the second spring 17. When the disassembly plate 10 is inserted into the outer shell 7, the limiting block 16 can be locked into the limiting groove of the outer shell 7 under the action of the second spring 17, thus playing a fixing role. When performing internal maintenance, by pressing the slider 18, the slider 18 slides within the sliding groove, causing the limiting block 16 to slide within the telescopic groove and squeeze the second spring 17, so that the limiting block 16 slides out from the limiting grooves at both ends of the outer shell 7, releasing the limiting, thus facilitating the separation of the outer shell 7 from the disassembly plate 10 for convenient internal maintenance.

[0035] It should be noted that the wiring connections between the exhaust fan 9, the toxic gas detection sensor 12, the alarm 14 and the controller 13 in this toxic gas monitoring and alarm device, as well as the internal wiring of each component, are all existing technologies and will not be described in detail here.
