Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

As shown in fig. 1 and 2, the utility model provides a pair of air sampling instrument, including square pipe 1 and sampling box 2, all be equipped with spout 12 on two relative inner walls of square pipe 1, the 1 upside of square pipe is equipped with opening 11.

2 relative bilateral symmetry fixed connection sliders 21 of sampling box, slider 21 can slide in spout 12 by the one-to-one, and 2 sliders 21 of sampling box slide through sliding in square pipe 1. In order to facilitate the sliding of the sampling box 2, a pull ring 22 is fixedly connected to one side of the sampling box 2. One side of the sampling box 2 is provided with an air pipe 3, and the air pipe 3 is provided with a valve 31. When the sample chamber 2 is located within the square tube 1, the gas tube 3 can pass through the opening 11.

The aspirator pump 4 is equipped with on one side of square pipe 1, and the interface that admits air of aspirator pump 4 passes through first hose 41 and connects end 5 of breathing in, square pipe 1 one side fixed connection cassette 51, and cassette 51 one side is equipped with the draw-in groove, and the end 5 activity joint of breathing in is in the draw-in groove. When sampling air, the sampling personnel can remove the suction tip 5 and move it to a different location for sampling. The air outlet interface of the air suction pump 4 is connected with the air pipe 3 through a second hose 42, and the second hose 42 is connected with the air pipe 3 in a buckling manner, so that the connection and the disassembly between the two hoses are convenient.

In order to prevent that sampling box 2 from droing in square pipe 1, square pipe 1 one end fixed connection baffle 6. Be equipped with through-hole 61 in baffle 6 one side, at sampling box 2 one side fixed connection inserted bar 23, when sampling box 2 inserted square intraductal 1 and contacted with baffle 6, inserted bar 23 can pass and stretch out to the square intraductal 1 outside in through-hole 61, is equipped with the stop device who is used for locking sampling box 2 in baffle 6 one side. Stop device includes fixed plate 62, and fixed plate 6 fixed connection all is equipped with the screw hole in every fixed plate 62 one side in baffle 6 one side, and screw hole internal thread fit connects screw rod 63, and inserted bar 23 one side is equipped with spacing hole 24, and screw rod 63 can insert to spacing downthehole 24.
