Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram that can be put into sampling bottle and open and take out the self-sealing needle assemblies closed.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Referring to Fig. 1, a kind of can be put into the self-sealing needle assemblies for opening and taking out and closing with sampling bottle, including accept ontology 5
Ontology 1 is connect fastly, and the inner lower for accepting ontology 5 is equipped with sliding block, and sliding block 10 is by the butt end and integrated molding on top thick
The taper end composition of lower part is held, the circumferential surface of the butt end of sliding block 10 is mutually sealed with the inner wall for accepting ontology 5 and is slidably connected, sliding block 10
Taper end extend the lower part for accepting ontology 5, the lower part for accepting ontology 5 is fixedly connected with end cap, the lower end one of end cap
The flange for stopping the butt end of sliding block 10 is formed, fixing to run through on sliding block 10 has air inlet needle tubing 14 and outlet needle tubing 13；It is described to hold
The bosom for connecing ontology 5 offers the first helical spring cavity, is equipped with the first helical spring in the first helical spring cavity
9, the outlet needle tubing 13 is connected with the first helical spring cavity, and the upper inside for accepting ontology 5 offers acquisition cavity
Body, the first helical spring cavity and acquisition cavity through hole road are connected, and the air inlet needle tubing 14 passes through 9 He of the first helical spring
Duct and the upper end are equipped with thimble 6, and thimble 6 is located in duct, and the side wall of the undertaking ontology 5 offers and the first helical spring
The outer round that cavity is connected；The inner lower of the acquisition cavity is equipped with lifting head 3, and fixed connect in top for acquiring cavity has
Ontology 1 is connect fastly, and lifting head 3 is connected by the second helical spring 2 with ontology 1 is connect fastly.It is embedded on the butt end of the sliding block 10
First rubber o-ring 11.The top of the spring cavity is fixedly connected with the second rubber o-ring 7 passed through by air inlet needle tubing 14.
