As a kind of preferred version, one end of described syringe needle connection tube is bullet end, another end band cylinder end, and described cylinder end is outside equipped with external screw thread.
As a kind of preferred version, endoporus one end of described sealing shroud and the bullet end of syringe needle connection tube are sealed and matched, and the other end is provided with the female thread matched with the external screw thread of syringe needle connection tube.
As a kind of preferred version, the side of described piston arranges seal groove, is provided with sealing ring in sealing groove.
As a kind of preferred version, described push-and-pull portion is provided with circular push-and-pull ring.
As a kind of preferred version, described syringe urceolus is provided with elastic force bar, and described elastic force bar is connected with elastic ball.
As a kind of preferred version, between described piston and syringe needle connection tube, be provided with barbed plastics sieve plate.
Compared with prior art, beneficial effect of the present invention: syringe of the present invention prevents syringe from being utilized by intentionally personage and threatens people's safety, and in use good sealing effect, no leakage, simple operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is A place enlarged drawing in Fig. 1.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of anti-leak syringe, comprises syringe urceolus 1, syringe needle 2, piston 3, piston boit 4, and described syringe urceolus 1 is connected with syringe needle connection tube 5, is arranged with sealing shroud 6 outside this syringe needle connection tube 5; Described syringe needle 2 passes sealing shroud 6 and is connected on syringe needle connection tube 5, and the liquid outlet of syringe needle 2 is arranged at outside sealing shroud 6; One end of described piston boit 4 is provided with Piston connecting portion 7, and the other end is provided with push-and-pull portion 8; The sidewall of described Piston connecting portion 7 is provided with elasticity resistance and moves back ring card 9, described elasticity resistance is moved back ring card 9 and is tilted towards push-and-pull portion 8; Described piston 3 is set on Piston connecting portion 7, and the sidewall of piston 3 is provided with piston shirt rim 10; Described syringe urceolus 1 inwall is provided with protuberance 11, and described protuberance 11 tilts towards syringe needle 2 direction; The side of described piston 3 arrange seal groove (owing to being provided with component, thus in figure and not shown), be provided with sealing ring 12 in sealing groove.When the present invention specifically implements, fixing on the Piston connecting portion 7 first piston 3 being sheathed on piston boit 4, then the piston boit 4 of band piston 3 is firmly inserted in syringe urceolus 1, now piston 3 shrinks, and ring card 9 also pressurized contraction is moved back in elasticity resistance, makes piston 3 force to enter in syringe urceolus 1, when retracting piston boit 4, elasticity resistance is moved back ring card 9 and is slid into protuberance 11 place and be obstructed and block, good seal performance, anti-leak.
One end of the preferred described syringe needle connection tube 5 of the present invention is bullet end, another end band cylinder end, and described cylinder end is outside equipped with external screw thread 13; Endoporus one end of described sealing shroud 6 and the bullet end of syringe needle connection tube 5 are sealed and matched, and the other end is provided with the female thread matched with the external screw thread of syringe needle connection tube 5.Wherein be threaded between syringe needle connection tube 5 with sealing shroud 6, both tighten by spiral, even if internal pressure is very high like this, syringe needle 2 also can not come off, inhale medicine or inject very safe, in addition, the tapered sealing portion between syringe needle connection tube 5 and sealing shroud 6 improves sealing effectiveness.
The preferred described push-and-pull portion 8 of the present invention is provided with circular push-and-pull ring 14.During concrete enforcement, finger inserts in circular push-and-pull ring 14 and extracts or liquid medicine injection, and improve the safety of syringe, it is more convenient to operate.
The preferred described syringe urceolus 1 of the present invention is provided with elastic force bar 15, and described elastic force bar 15 is connected with elastic ball 16.Elastic force bar 15 is beaten when carrying out intramuscular injection to patient, easy and simple to handle, time saving and energy saving, alleviate the workload of medical worker.
