Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and 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 to 3, in an embodiment of the present invention, a retractable type comprehensive sampler for environment detection includes a sampler body and a retractable bracket.

The sampler body comprises a steel column 6, a dust fall cylinder bracket 8 and a dust fall cylinder 9. The steel column 6 is formed by welding a cylindrical column and a cuboid square 5, and through holes are formed in the upper part of the column and the bottom of the cuboid; the dust settling cylinder bracket is concave, the two ends are high, the middle is low, and a through hole is formed in the middle; the steel column 6 and the dust settling cylinder support 8 are fixedly connected statically through a pin shaft, and the dust settling cylinder 9 is an organic glass dust settling cylinder.

The cylindrical column in the steel column 6 is a hollow column body, the length of the cylindrical column is about one meter, and a through hole in the upper part of the cylindrical column is in pin shaft connection with a through hole 7 in the middle part of the dustfall cylinder support.
