Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution:
the utility model provides an easy disconnected formula glass sampling pipe, includes sampling pipe body 1, the both ends of sampling pipe body 1 are provided with sealed end 3, are provided with concave part 2 between sampling pipe body 1 and sealed end 3, set up on concave part 2's pipe wall and easily break disconnected line of cut 4 with sealed end off with the fingers and thumb, placed active carbon or silica gel filling layer 5 inside sampling pipe body 1 and be used for adsorbing the chemical substance that gets into in the sampling pipe, 1 both ends of sampling pipe body still are provided with and are used for the card cap 7 that covers sealed end. Sampling pipe body 1 is hollow cylinder pipe, concave part 2 is hollow structure, conveniently gathers the air after sealed end 3 breaks off with the fingers and thumb. Sealed end 3 is hollow structure or solid construction, and sampling pipe body 1, concave part 2 and sealed end 3 adopt glass material integrated into one piece.
Be provided with external screw thread 6 on the lateral wall at sampling pipe body 1 both ends, be provided with the internal thread 8 that matches with external screw thread 6 on the inside wall of card cap 7, thereby external screw thread 6 and internal thread 8 are supporting realizes blocking cap 7 fixed cover on sampling pipe body 1 after the sampling is accomplished.
