Abstract

The invention provides a telescopic multifunctional soot / gas sampling tube with an adjustable length, which can solve problems caused by unadjustable length during carrying, transporting and storing of the sampling tube. The technical scheme is that the sampling tube comprises a protection tube and a lengthening protection tube, wherein the lengthening protection tube is sleeved on the protectiontube. The sampling tube is characterized by also comprising a locking head, a locking screw cap and a locking sleeve, wherein the locking sleeve and the locking head are sleeved on the body of the protection tube; the locking sleeve is sleeved in the cavity of the locking screw cap; the locking head is fixed with the front end of the lengthening protection tube; and the locking screw cap is connected with the locking head through threads. After the telescopic multifunctional soot / gas sampling tube with the adjustable length is used, a hose can be conveniently taken down, and after connecting and locking parts of the sampling tube are loosened, the sampling tube returns to a smaller size for carrying, transporting and storing, thereby solving the problem of inconvenience caused by the length problem in the carrying, transporting and storing processes.

Description

technical field [0001] The invention relates to an environmental monitoring instrument, in particular to a telescopic smoke dust / gas multifunctional sampling tube with adjustable length. Background technique [0002] At present, in the process of using the dust / gas multifunctional sampling tube to sample fixed pollution sources, the generally used dust / gas multifunctional sampling tube is composed of a single tube with a fixed length and cannot be stretched. This fixed-length dust / gas multifunctional sampling tube generally has a length of more than 1.5 meters, which is very inconvenient whether it is used, carried, transported, or stored, and brings many problems to the implementation of the specific sampling process. . Contents of the invention [0003] The invention provides a telescopic dust / gas multifunctional sampling tube with adjustable length, which can solve some problems caused by the non-adjustable length of the sampling tube during carrying, transportation an...
