Embodiment
As shown in Figures 1 to 12, a kind of air tube syringe, including syringe 1 and plunger 2, the plunger 2 include piston body
21 and be fixed on the seal I 22 and seal II 23 of the end of piston body 21, the inwall of the seal I 22 and syringe 1 it
Between it is in sealing contact, the edge of seal I 22 is made up of rubber, between the seal II 23 and the inwall of syringe exist seam
Gap, the seal II 23 includes diaphragm seal 24 and is arranged on diaphragm seal 24 and perpendicular to the body of rod 25 of diaphragm seal, described close
Sealing I 22 is provided with mounting hole 26 and passage 27, and the body of rod 25 is through mounting hole 26 and the body of rod 25 and seal I 22
The elastic component 28 of passage 27 is closed provided with making seal I 22 and seal II 23 fit, in the present embodiment, the seal
I 22 end face is provided with the interior concave space of the seal II 23 for accommodating, and passage 27 is arranged on the position of interior concave space, institute
The inwall for stating the close openend of syringe 1 is provided with and can stop spacing spacing block piece 11 to the progress of the body of rod 25.
Described one end of the body of rod 25 is fixedly connected with diaphragm seal 24, the other end be provided with flange 29, the elastic component for set with
Spring between flange 29 and diaphragm seal 24.
The spacing block piece 11 is hollow cylindrical structure, and the outer wall of the spacing block piece 11 is provided with circumferential ring
