The specific embodiment
Below in conjunction with accompanying drawing this utility model is done following the detailed description.
Shown in accompanying drawing; The syringe of a kind of detachable needle of this utility model; Its structure comprises syringe needle 1, needle tubing 5, and the needle tubing 5 that front end is provided with positioning convex 3 is provided with dismounting tube 2, and dismounting tube 2 is enclosed within needle tubing 5 front ends and is slidingly connected with it; Dismounting tube 2 lower ends are provided with flange 4, and flange 4 tops are promptly dismantled tube 2 and are provided with chute 8; Positioning convex 3 is arranged in the chute 8 and with it and matches.
Positioning convex 3 is provided with two and about needle tubing 5 centrosymmetry settings.Dismounting tube 2 internal diameters match with needle tubing 5 external diameters; Dismounting tube 2 is processed by transparent plastic.
When using syringe, seeing the scale 6 on the needle tubing 5, operation push rod 7 is accomplished injection work, and hands top flange 4 moves upward dismounting tube 2 then, and syringe needle 1 is broken away from needle tubing 5.
The direction of motion that positioning convex 3 can be controlled dismounting tube 2 can not depart from, and does not hinder user to observe scale 6, and can prevent dismounting tube 2 when user dismounting syringe needle 1 because inertia breaks away from needle tubing 5 with syringe needle 1, to avoid accident.The flange 4 that dismounting tube 2 lower ends are provided with can help user easily syringe needle 1 to be broken away from.
Its processing and fabricating of the syringe of a kind of detachable needle of this utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be this professional's known technology.
