Technical Field

[0001] This utility model relates to the field of chemical gas testing, specifically a portable multi-channel sampling device for professional chemical gas testing. Background Technology

[0002] In the fields of chemical gas testing, such as environmental monitoring, industrial safety, and laboratory analysis, sampling devices are key equipment for obtaining gas samples. Their performance directly affects the accuracy and reliability of test results. In actual operations, it is often necessary to collect multiple gas samples in different scenarios, which places high demands on the portability and multi-gas storage capacity of the device.

[0003] Currently, most gas sampling devices on the market are either fixed or bulky portable structures. The former cannot meet the needs of mobile sampling on site, while the latter, although portable, are heavy and have a cumbersome structure, which can easily cause operator fatigue when carried for a long time. At the same time, the gas storage units of existing devices are mostly single chambers or a few independent chambers, which makes it difficult to store multiple gas samples with different properties at the same time, and cross-contamination is likely to occur. Moreover, the storage chamber capacity is fixed and cannot be flexibly adjusted according to the sampling volume, which limits its applicability. Therefore, it is necessary to design a portable multi-channel sampling device for chemical gas testing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a portable multi-channel sampling device for chemical gas testing, in order to solve the problems mentioned in the background art.

[0006] The surface of the gas storage tank is rotatably connected to a rotating shaft via a bearing component, and several rotating shafts are provided. A limit plate is fixedly installed on the surface of the rotating shaft, and one end of the pull rope extending to the outside of the gas storage tank is fixedly connected to the bottom of the rotating shaft.

[0009] Preferably, a spring is welded to the bottom of the piston, and the bottom end of the spring is welded to the bottom of the gas storage groove cavity.

[0010] Preferably, one side of the side plate is slidably connected to a slide rod through an opening, and both ends of the slide rod are fixedly fitted with abutments.

[0011] Preferably, a handle is fixedly installed between the two side plates.

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

[0013] 1. This portable multi-channel sampling device for chemical gas testing uses multiple gas storage tanks. By rotating a limiting disc, the limiting disc drives a rotating shaft. The rotating shaft pulls a rope outward, causing a piston to descend. After the piston descends, the chemical gas is drawn into the gas storage tank through a gas guide tube, thus facilitating the collection of various chemical gases. After collection, the gas guide tube can be bent to the pad, and then the side plate can be flipped. The flipping of the side plate causes the limiting plate to flip as well. After flipping, the limiting plate can be inserted into the limiting slot, thus achieving the effect of limiting the limiting disc.

[0014] 2. This portable multi-channel sampling device for chemical gas testing uses a pressure plate that can be flipped to press down on the gas delivery tube, thus storing it. After the gas delivery tube is stored, the two sliding rods on both sides can be pushed towards the middle simultaneously. The sliding rods move so that the stop block is pressed tightly against the top of the gas storage box, thereby limiting the side plate. After the side plate is limited, the staff can carry the device by holding the handle, achieving a portable effect. Attached Figure Description

A gas guide tube 8 is fixedly installed on the top of the inner cavity of the gas storage slot 2 through an opening. A solenoid valve is provided on the surface of the gas guide tube 8. A piston 3 is slidably connected inside the gas storage slot 2. A pull rope 6 is fixedly installed on the top of the piston 3. The bottom end of the pull rope 6 passes through the gas storage box 1 and extends to the outside of the gas storage box 1.

[0024] Specifically, a rotating shaft 4 is rotatably connected to the surface of the gas storage tank 1 via bearing components, and several rotating shafts 4 are provided. A limiting plate 5 is fixedly installed on the surface of the rotating shaft 4. One end of the pull rope 6 extending to the outside of the gas storage tank 1 is fixedly connected to the bottom of the rotating shaft 4. A limiting plate 11 is fixedly installed on the bottom of the pressure plate 10. The bottom of the limiting plate 11 passes through the limiting plate 5 and extends into the interior of the limiting plate 5. A limiting groove 12 is formed on the surface of the limiting plate 5 to cooperate with the limiting plate 11, and several limiting grooves 12 are provided. By setting multiple gas storage grooves 2 and rotating the limiting plate 5, the limiting grooves 12 are adjusted to allow the pressure plate 10 to rotate. The position plate 5 drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 can pull the pull rope 6 outward. The pull rope 6 being pulled out causes the piston 3 to descend. After the piston 3 descends, the chemical gas can be drawn into the interior of the gas storage tank 2 through the gas guide pipe 8, thereby achieving the effect of collecting various different chemical gases. After collection, the gas guide pipe 8 can be bent to the pad plate 13, and then the side plate 9 can be flipped. The flipping of the side plate 9 can drive the pressure plate 10 to flip. The flipping of the pressure plate 10 can drive the limiting plate 11 to flip. After the limiting plate 11 flips, it can be inserted into the inner side of the limiting groove 12, thereby achieving the effect of limiting the limiting plate 5.

[0025] Specifically, side plates 9 are rotatably connected to both sides of the gas storage box 1 via bearing components. A pressure plate 10 is fixedly installed on the front side between the two side plates 9. A pad 13 is fixedly installed on the surface of the gas storage box 1. One end of the air guide tube 8 extends between the pressure plate 10 and the pad 13. A spring 7 is welded to the bottom of the piston 3. The bottom end of the spring 7 is welded to the bottom of the inner cavity of the gas storage groove 2. A sliding rod 15 is slidably connected to one side of the side plate 9 through an opening. A stop block 16 is fixedly installed at both ends of the sliding rod 15. A handle 14 is fixedly installed between the two side plates 9. By setting the pressure plate 10, the air guide tube 8 can be pressed after the pressure plate 10 is flipped, achieving the effect of storing the air guide tube 8. After the air guide tube 8 is stored, the two sliding rods 15 can be pushed towards the middle at the same time. The sliding rods 15 move so that the stop block 16 is pressed tightly against the top of the gas storage box 1, thereby achieving the effect of limiting the side plate 9. After the side plate 9 is limited, the operator can carry the device through the handle 14, achieving a portable effect.

[0026] Working Principle: This utility model is a portable multi-channel sampling device for chemical gas testing. It features multiple gas storage tanks 2. Rotating the limiting disc 5 causes the rotating shaft 4 to rotate, pulling out a pull rope 6. This pull causes the piston 3 to descend, drawing chemical gas into the gas storage tanks 2 through the gas guide tube 8. This facilitates the collection of various chemical gases. After collection, the gas guide tube 8 can be bent to the pad 13, and then the side plate 9 can be flipped. Flipping the side plate 9 allows for the collection of chemical gases. The pressure plate 10 flips, which in turn causes the limiting plate 11 to flip. After the limiting plate 11 flips, it can be inserted into the limiting groove 12, thereby achieving the effect of limiting the limiting plate 5. At the same time, the flipping of the pressure plate 10 can press the air guide tube 8, achieving the effect of storing the air guide tube 8. After the air guide tube 8 is stored, the sliding rods 15 on both sides can be pushed towards the middle at the same time. The sliding rods 15 move so that the abutment 16 is in close contact with the top of the air storage box 1, thereby achieving the effect of limiting the side plate 9. After the side plate 9 is limited, the operator can carry the device through the handle 14, achieving the effect of portability.
