Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1 to 3, in the present embodiment, the main body of the liquid sampling bag is a bag body 4, the bag body 4 is made of a transparent composite plastic material by a wide welding technique, the top of the bag body 4 is provided with a collection port, a cover seat 2 is disposed at the collection port, and the bag body 4 is hermetically attached to the bag body 4 at the position of the cover seat 2 corresponding to the collection port and is welded and fixed.

Lid seat 2 closes fixedly with screw top cap 1 soon through thread flank 9, and the outside of thread flank is provided with reverse locking structure, this reverse locking structure connects line 10 and sets up in screw top cap 1 inboard second soon including setting up in the first line 10 that connects soon of lid seat 2 inboard and connect line 11, first connect line 10 and second soon to connect line 11 to set up relatively, its structure is unanimous, the section is right triangle, can close soon according to the arrow point direction that figure 3 shows, close the in-process soon, first connect line 10 and second soon connect the inclined plane of line 11 relatively and continuously to compress tightly, and make right triangle's right-angle side push up each other and lean on and realize locking after joining in place soon.
