Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically to a gas detection sample sampling rod. Background Technology

[0002] The gas sampling rod can not only extract gas at different heights, but also can be inserted into a stockpile to extract gas from within the stockpile, making it a convenient auxiliary tool for gas extraction.

[0003] In existing gas sampling rods, the sampled gas needs to flow from the top of the sampling rod to the bottom using a flexible tube to guide the gas into the sampling bottle. The sampling rod acts as a gas guide, and the gas flows entirely through the interior of the sampling rod. Therefore, there is initial gas inside the sampling rod. The mixing of the initial gas inside the sampling rod with the extracted sampled gas can easily affect the accuracy of gas detection. Utility Model Content

[0004] The purpose of this invention is to provide a gas detection sample sampling rod to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas detection sample sampling rod, comprising a sampling rod body, wherein the top side wall of the sampling rod body has equally spaced air intake ports, a first piston plate and a second piston plate are slidably connected to the top inner wall of the sampling rod body, the second piston plate is located at the bottom of the first piston plate, a traction rope is connected to one end of the bottom of the first piston plate, the other end of the traction rope is connected to the top outer wall of the second piston plate, and a vertically downward pulling rod is fixedly provided on the bottom outer wall of the second piston plate, and a pulling handle is fixedly provided at one end of the bottom of the pulling rod.

[0006] Preferably, a filter screen is fixedly provided on the top outer wall of the sampling rod body, and the air inlet is located inside the filter screen. The filter screen can prevent impurity particles from entering the sampling rod body.

[0007] Preferably, the top side of the sampling rod body is connected to a downwardly curved exhaust pipe through an opening. An exhaust valve is installed on the exhaust pipe, and an exhaust pipe connector is installed at the bottom end of the exhaust pipe. The exhaust pipe connector facilitates the connection between the exhaust pipe and the sampling gas container.

[0008] Preferably, a fixing ring is fixedly provided on the top outer wall of the sampling rod body, and elastic clips are fixedly provided on one side outer wall of the fixing ring at equal intervals. The elastic clips are located on the bottom side of the exhaust pipe, and the container for sampling gas can be easily clamped by the elastic clips.

[0009] Preferably, a rubber sleeve is fitted onto the bottom outer wall of the sampling rod body, which facilitates the handling of this utility model.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0011] By pulling the handle upwards, the pull rod is driven to push the second piston plate upwards on the inner wall of the sampling rod body, so that the top outer wall of the second piston plate and the bottom outer wall of the first piston plate are in contact. This facilitates the discharge of the original gas between the first and second piston plates, avoids the presence of original gas from the sampling rod body between the first and second piston plates, and prevents the original gas from the sampling rod body from mixing into the sampling gas, which helps to improve the accuracy of gas sampling.
