Description

Technical Field

[0001] The utility model relates to the technical field of natural gas detectors, in particular to a handheld natural gas detector device. Background Art

[0002] The natural gas detector is a natural gas leak detection and alarm instrument, and its purpose is to ensure safe production. When the natural gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the natural gas alarm will send out an alarm signal to remind workers to take safety measures and drive the exhaust, cut-off, and spray systems to prevent explosions, fires, and poisoning accidents.

[0003] During use, existing natural gas detector devices are often fixed by a large number of screws. However, long-term use and storage often cause the screws to age and rust, which further makes it impossible to disassemble and repair, resulting in poor practicality of the natural gas detector device. Utility Model Content

[0004] The purpose of the utility model is to provide a handheld natural gas detector device to overcome the above-mentioned defects in the prior art.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A handheld natural gas detector device comprises a main box body, wherein an exhaust chamber is arranged in the main box body, and two groups of limit frames are fixedly provided with left and right symmetrical end faces of the left and right sides of the main box body, a limit chamber connected to the outside is arranged in the limit frame, a feed chamber is arranged in the main box body and is mutually connected with the exhaust chamber, a rotating fan blade is rotatably provided on the rear wall of the exhaust chamber, and the rotating fan blade plays the role of exhausting air, a cover frame is provided on the upper side of the main box body and covers the exhaust chamber, a positioning frame is fixedly provided on the upper end face of the exhaust chamber, a threaded chamber connected to the outside is arranged in the positioning frame, and two groups of threaded sliders with opposite threads and capable of moving toward each other are arranged in the threaded chamber, a moving frame is fixedly provided on the end face of the threaded slider away from the center of symmetry, and a limit slider is fixedly provided on the end face of the mobile frame close to the center of symmetry and is inserted into the limit chamber, thereby ensuring the function of easy disassembly.

[0007] Preferably, a threaded screw is rotatably provided between the left and right walls of the threaded cavity and passes through the right wall of the threaded cavity. The threaded screw is threadedly matched with the threaded slider. A controller is fixedly provided on the rear end face of the positioning frame, and the controller plays a coordinating role in regulating various movements.

[0008] Preferably, a pull-out frame that can move up and down is provided in the lid frame, a filter net is fixed in the pull-out frame, and the filter net plays a filtering role, a metal block is fixed on the upper end surface of the pull-out frame, and an electromagnet is fixed on the upper end surface of the lid frame, and the electromagnet cooperates with the metal block magnetically.

[0009] Preferably, a rotating motor is fixedly provided in the rear wall of the exhaust chamber, the rear end surface of the rotating fan blade is dynamically connected to the rotating motor, two groups of exhaust holes are symmetrically provided on the rear wall of the exhaust chamber and are interconnected with the exhaust chamber, and a handle is fixedly provided on the rear end surface of the main box body.

[0010] Preferably, a natural gas detector body is fixedly provided on the lower wall of the exhaust chamber, so that the natural gas detector body plays a role in detecting natural gas, and an alarm is fixedly provided on the lower end surface of the main box body, so that the alarm plays a role in alarming.

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] 1. The effect of the utility model is that the natural gas detector body starts to detect whether there is a natural gas leak in the pipeline in the air. When the natural gas exceeds the standard, the alarm starts to sound, and then the air is discharged to the outside through the exhaust hole, thereby realizing the detection process of natural gas. Due to the long-term use of the front side of the filter, a large amount of dust is adsorbed. At this time, the controller is controlled, and the magnetic force generated by the electromagnet disappears. At this time, the pull-out rack and the filter can be directly removed, so as to facilitate the subsequent cleaning of the dust adsorbed on the front side of the filter, thereby ensuring the cleaning efficiency and further ensuring the sensitivity during detection.

[0013] 2. The effect of the utility model is that: the threaded screw is rotated, and then the two groups of threaded sliders that are symmetrical and have opposite threads start to move away from the movable frame and the limit slider, and then the limit slider starts to move away from the limit cavity, and then the cover frame starts to be quickly removed. When the cover frame is away from the main box body, it is ensured that a large number of parts begin to be exposed to the outside world, so as to facilitate the subsequent repair and maintenance of the device, thereby changing the existing problem of a large number of screws fixing and aging easily after long-term use, and then inconvenient to open, thereby ensuring the practicality of the device.

[0028] Specific workflow:

[0029] During use, the user holds the handle 18, and the main box body 11 begins to cover the outside of the household pipe. The rotating motor 13 starts to start, thereby driving the rotating fan blades 14 to start rotating at high speed. The feed chamber 32 begins to extract air from the outside of the pipe, and enters the exhaust chamber 12. After being filtered by the filter 23, the natural gas detector body 15 begins to detect whether there is a natural gas leak in the pipe in the air.
