Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Example (b): referring to fig. 1-4, a sampling device for industrial waste gas detection, including urceolus 1, there is a sampler barrel 2 through threaded connection in the urceolus 1, make sampler barrel 2 can separate with urceolus 1, the both ends of sampler barrel 2 all fixedly cup joint connecting pipe 15, sliding sleeve has been cup jointed in the sample urceolus 1 and run through and extend to urceolus 1 outside push rod 5, sliding sleeve has piston 6 in the sampler barrel 2, be provided with the connecting piece between piston 6 and the push rod 5, still be provided with the sealing member on the piston 6, avoid waste gas to leak.

When needs sample industrial waste gas, under the effect of connecting piece through push rod 5 for piston 6 removes in sampler barrel 2, with outside waste gas suction sampler barrel 2 in, later plug up one of them connecting pipe 15 through the sealing member, simultaneously at the in-process of extraction, piston 6 is close to another connecting pipe 15 gradually, thereby makes waste gas save in the sampler barrel 2, and then accomplishes the sample.

The sealing member includes a plurality of connecting rods 8 of fixed connection on piston 6, and the other end fixedly connected with second connecting block 9 of connecting rod 8, second connecting block 9 passes through threaded connection with one of them connecting pipe 15.

When needs sample industrial waste gas, under the effect of connecting piece through push rod 5, make piston 6 remove in sampler barrel 2, with outside waste gas suction sampler barrel 2 in, piston 6 removes and drives connecting rod 8 and remove, and then make the one end of second connecting block 9 enter into in the connecting pipe 15, in this embodiment, second connecting block 9 and connecting pipe 15 looks adaptation, later rotate second connecting block 9, make second connecting block 9 enter into in the connecting pipe 15 gradually, and piston 6 is close to another connecting pipe 15 gradually, thereby make waste gas save in the sampler barrel 2, and then accomplish the sample.

In consideration of convenience of rotation of the second connection block 9, as shown in fig. 2, a knob 10 is fixedly connected to the second connection block 9, and a diameter of the knob 10 is larger than a diameter of the connection pipe 15, and in this embodiment, when the second connection block 9 completely enters the connection pipe 15, the knob 10 abuts against the connection pipe 15.

As shown in fig. 2 and 4, the connecting member includes a first connecting block 7 fixedly connected to the piston 6, a groove 701 is formed in the first connecting block 7, a plurality of limiting grooves 702 are formed in the groove 701, and a clamping member clamped with the limiting grooves 702 is arranged in the push rod 5.

Under the effect of joint spare for push rod 5 is connected with first connecting block 7, and then can promote piston 6 and remove in sampler barrel 2.

As shown in fig. 2, the first connecting block 7 is connected with another connecting pipe 15 through a screw thread, the knob 10 is rotated to drive the second connecting block 9 to rotate, and then the piston 6 is driven to rotate through the connecting rod 8, so that the first connecting block 7 rotates, the first connecting block 7 gradually enters into another connecting pipe 15, the sampling cylinder 2 is completely in a sealing state, and leakage of internal waste gas is prevented.

As shown in fig. 3, a cavity 501 is formed in the push rod 5, two symmetrically distributed connecting plates 12 are arranged in the cavity 501, one side of each of the two connecting plates 12, which is close to each other, is fixedly connected with a plurality of limiting springs 13, and one side of each of the two connecting plates 12, which is far away from each other, is fixedly connected with a protruding block 14 which penetrates through and extends to the outside of the push rod 5 and a plurality of limiting blocks 11 which are clamped with the limiting grooves 702.

When the outer barrel 1 and the sampling barrel 2 need to be separated, the lug 14 is pressed, the two connecting plates 12 are close to each other, the limiting spring 13 is compressed, the limiting block 11 is gradually separated from the limiting groove 702 and enters the cavity 501, and then the push rod 5 is pulled out outwards, so that the push rod 5 and the first connecting block 7 can be separated; the sampling barrel 2 is then rotated so that the sampling barrel 2 is separated from the outer barrel 1.

As shown in fig. 1, a handle 4 is fixedly connected to the side wall of the outer cylinder 1, and a rotating handle 3 is fixedly connected to the side wall of the sampling cylinder 2.
