Detailed Description

For a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings.

In the embodiment 1, as shown in fig. 1 and 2, the utility model provides a disposable sealed sewage sampling test tube, which comprises a sealing component 1, wherein the sealing component 1 comprises a sealing tube 2, a lower sealing rubber plug 3 and an upper sealing rubber plug 4, the upper part of the sealing tube 2 is in threaded connection with a sampling tube 5, the lower sealing rubber plug 3 is arranged at the bottom of an inner cavity of the sealing tube 2, the upper sealing rubber plug 4 is arranged at the bottom of the inner cavity of the sampling tube 5, the lower sealing rubber plug 3 and the upper sealing rubber plug 4 are connected through a connecting rope A6, the upper part of the upper sealing rubber plug 4 is fixedly connected with a connecting rope B7, the upper part of the sampling tube 5 is in threaded connection with a sealing cover 8, the connecting rope B7 and the sealing cover 8 are in penetrating arrangement, and the side wall of the sealing tube 2 is communicated with a water inlet pipe 9.

The length of the connecting rope A6 is smaller than that of the sampling tube 5, and the connecting rope A6 can drive the lower sealing rubber plug 3 to completely seal the water inlet pipe 9.
