Description

Technical Field

[0001] The utility model relates to the technical field of gas detectors, in particular to a portable explosion-proof all-in-one gas detector. Background Art

[0002] With the development of cities, urban construction has gradually expanded. Green construction is now advocated in the construction process, which is not only to protect the environment but also to protect the construction workers. In the process of green construction, workers often need to detect the gas on site, and the all-in-one gas detector is a tool that can detect multiple gases at the same time. At the same time, different detection probes can be replaced according to the different conditions that need to be detected on site, so as to realize the detection of different gases. Compared with general single gas detection detectors, the all-in-one gas detector is easier for workers to carry and use.

[0003] In the prior art, after the gas detector has been used for a period of time, since there is no protective mechanism on the air inlet, insect corpses will inevitably remain on the air inlet, which is inconvenient to clean. Moreover, when the gas detector is not in use, it is not convenient to close the air inlet, resulting in a large amount of dust entering and affecting the detection effect. Therefore, we have launched a portable explosion-proof all-in-one gas detector. Utility Model Content

[0004] The purpose of the utility model is to provide a portable explosion-proof all-in-one gas detector, which is not only convenient for preventing insect corpses from remaining in the air intake pipe, but also convenient for cleaning insect corpses blocked on the filter, saving time and effort and being highly efficient. It is also convenient for sealing the air intake pipe when not in use to reduce dust entry and ensure the detection effect, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A portable explosion-proof multi-in-one gas detector comprises a detector body, a display screen is fixedly provided on the front side of the detector body, a carrying rod is provided on the upper end of the detector body, a sound and light alarm is provided on one side of the detector body, a detection mechanism is provided on the other side of the detector body, a plurality of air inlet pipes are fixedly provided on the lower end of the detection mechanism, a clamping plate is provided below the plurality of air inlet pipes, a filter ring is provided between the plurality of air inlet pipes and the clamping plate, an annular limiting groove is provided at the upper end of the filter ring, the annular limiting groove is matched with the lower end of the air inlet pipe, a filter net is fixedly provided inside the filter ring, through holes are provided at the positions corresponding to the positions of the clamping plate and the plurality of filter rings, sliding holes are symmetrically provided on both sides of the clamping plate, and a clamping mechanism is provided between the sliding hole and the detection mechanism.

[0007] Preferably, the clamping mechanism includes a sliding rod, which is slidably arranged in a sliding hole, and both ends of the sliding rod extend to the outside of the sliding hole. The upper end of the sliding rod is fixedly connected to the detection mechanism, and the lower end of the sliding rod is fixedly provided with a circular stopper. The rod wall of the sliding rod is located between the clamping plate and the circular stopper and is provided with a spring.

[0008] Preferably, the diameter of the circular stopper is greater than the diameter of the spring.

[0009] Preferably, a U-shaped pull rod is fixedly provided at the lower end of the abutting plate.

[0010] Preferably, a protective plate is provided at each of the plurality of through holes at the bottom of the abutting plate, and one side of the protective plate is rotatably connected to the abutting plate via a damping shaft.

[0011] Preferably, the filter screen is a stainless steel metal screen.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The portable explosion-proof all-in-one gas detector is provided with a detection mechanism, a carrying rod, a detector body, an audible and visual alarm, a display screen, an air inlet pipe, a clamping plate, a protective plate, a U-shaped pull rod, a filter ring, a circular block, a spring, a sliding rod, a damping shaft, and a filter screen. When the filter screen needs to be cleaned, the U-shaped pull rod is pulled downward, and the U-shaped pull rod drives the clamping plate to squeeze the spring. At the same time, the clamping plate no longer clamps the filter ring, and the filter ring can be removed to clean the insect corpses remaining on the filter screen. After the use of the device, the protective plate is pushed to rotate 180 degrees around the damping shaft, and the protective plate can block the through hole to reduce the entry of dust into the air inlet pipe. This is not only convenient for blocking the insect corpses from remaining in the air inlet pipe, but also convenient for cleaning the insect corpses blocked on the filter screen, which saves time, labor, and is highly efficient. It is also convenient to close the air inlet pipe when not in use to reduce the entry of dust, thereby ensuring the detection effect. BRIEF DESCRIPTION OF THE DRAWINGS
