Compared with prior art, the anti-pollution injector of easy assembling of the present invention arranges elastic ring by arranging two with the cylindricality connector of draw-in groove and at the two ends of described elasticity mantle sleeve pipe, and the elastic ring that makes described elasticity mantle sleeve pipe is stuck in the draw-in groove of corresponding cylindricality connector the two ends of described elasticity mantle sleeve pipe are fixed on two described cylindricality connectors, this mode being fixed only needs an installation procedure to complete, greatly reduce installation difficulty, and work efficiency improves obviously, and the setting of guiding cone can make the installation at described elasticity mantle sleeve pipe two ends simpler and easy, because the wall thickness of described elasticity mantle sleeve pipe is less than or equal to 0.3mm, compare the attenuation substantially of elasticity mantle sleeve pipe with elasticity mantle sleeve pipe of the prior art, thereby when pulling described column push rod to take out medicine, not only taking out medicine resistance reduces greatly, even if described elasticity mantle sleeve pipe can shrink, can not block passage, guarantee anti-pollution injector smooth gas discharge yet, because the degree of depth of draw-in groove is not less than the cross-sectional diameter of described elastic ring, no matter described draw-in groove is straight trough or curved slot, described elastic ring can be clamped in described draw-in groove, described elasticity mantle sleeve pipe is combined firmly with described cylindricality connector, difficult drop-off, and described draw-in groove is while being straight trough, also can make the dismounting of described elasticity mantle sleeve pipe be more prone to.
By following description also by reference to the accompanying drawings, it is more clear that the present invention will become, and these accompanying drawings are used for explaining embodiments of the invention.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of anti-pollution injector of the prior art.
Fig. 2 is the easily schematic diagram of the anti-pollution injector of assembling of the present invention.
The specific embodiment
With reference now to accompanying drawing, describe embodiments of the invention, in accompanying drawing, similarly element numbers represents similar element.
Please refer to Fig. 2, the anti-pollution injector of described easy assembling comprises syringe 1, and the front end of described syringe 1 is provided with liquid in-out mouth 11.The rear end of described syringe 1 is provided with wing plate 12, and described wing plate 12 centers are provided with the through hole 12a with syringe 1 internal communication.In described syringe 1, be provided with piston 2 and the column push rod 3 that is connected described piston 2.The outer elasticity mantle sleeve pipe 4 that is arranged with of described column push rod 3.
The rear and front end of described column push rod 3 is equipped with the cylindricality connector 5 being connected with described elasticity mantle sleeve pipe 4 two ends respectively, and the cylindricality connector 5 that is positioned at described column push rod 3 front ends is fixedly connected with described column push rod 3.In this specific embodiment, the cylindricality connector 5 that is positioned at described column push rod 3 front ends is structure as a whole with described column push rod 3.In other embodiments, the cylindricality connector 5 that is positioned at described column push rod 3 front ends also can be fixedly connected with by screw threads for fastening or other mode being fastenedly connected with described column push rod 3.The cylindricality connector 5 that is positioned at described column push rod 3 rear ends is fastened on the through hole 12a place of described wing plate 12 just, and this cylindricality connector 5 and described column push rod 3 matched in clearance, thereby described column push rod 3 can be pulled and promote.Particularly, the cylindricality connector 5 that is positioned at described column push rod 3 rear ends is provided with the passage 5a with described syringe 1 internal communication, in described passage 5a, is provided with air-filtering membrane (not shown).Described in each, cylindricality connector 5 is extended with guiding cone 51 towards the length direction of described elasticity mantle sleeve pipe 4, to facilitate, described elasticity mantle sleeve pipe 4 two ends guidings is inserted in corresponding guiding cone 51, makes the installation of elasticity mantle sleeve pipe 4 simpler and easy.In this specific embodiment, the cylindrical of guiding cone 51 described in each is all concaved with draw-in groove 5b.In other embodiments, described draw-in groove 5b also can be between described guiding cone 51 and described cylindricality connector 5 or be arranged on described cylindricality connector 5 cylindricals.And, in other embodiments, also can only there is described cylindricality connector 5 and not there is described guiding cone 51, at this moment described draw-in groove 5b is set directly on described cylindricality connector 5 cylindricals.In this specific embodiment, described in each, the draw-in groove 5b of cylindricality connector 5 is preferably straight trough.In other embodiments, described in each, the draw-in groove 5b of cylindricality connector 5 can be also the curved slot of the length direction bending towards described elasticity mantle sleeve pipe 4.
The rear and front end of described elasticity mantle sleeve pipe 4 is all elastic rings 6.In this specific embodiment, described in each, elastic ring 6 is glue ring.In other embodiments, described elastic ring 6 also can have elastic material by other and makes.The thickness of described elastic ring 6 is much larger than the wall thickness of described elasticity mantle sleeve pipe 4, and the wall thickness of described elasticity mantle sleeve pipe 4 is less than or equal to 0.3mm.The wall thickness of described elasticity mantle sleeve pipe 4 can be processed between 0.03-0.3mm as required.The elastic ring 6 of described elasticity mantle sleeve pipe 4 rear and front ends is stuck in the draw-in groove 5b of corresponding guiding cone 51 just, the cross-sectional diameter of described elastic ring 6 is less than or equal to the degree of depth of described draw-in groove 5b, described elastic ring 6 just can be housed in described draw-in groove 5b, this mode being fixed greatly reduces installation difficulty, thereby has greatly improved work efficiency.Because the cross-sectional diameter of described elastic ring 6 is less than or equal to the degree of depth of described draw-in groove 5b, no matter described draw-in groove 5a is straight trough or curved slot, described elastic ring 6 can be clamped in described draw-in groove 5b, make described elasticity mantle sleeve pipe 4 firm with described cylindricality connector 5 combinations, difficult drop-off, and described draw-in groove 5a is while being straight trough, also can make the dismounting of described elasticity mantle sleeve pipe 4 be more prone to.Because the wall thickness of described elasticity mantle sleeve pipe 4 is 0.1mm, thinner much than elasticity mantle sleeve pipe of the prior art, thereby when pulling described column push rod 3 to take out medicine, not only taking out medicine resistance reduces greatly, even if described elasticity mantle sleeve pipe 4 can shrink, can not block passage 5a, guarantee anti-pollution injector smooth gas discharge yet.
Invention has been described for above combination most preferred embodiment, but the present invention is not limited to the embodiment of above announcement, and should contain the various modifications of carrying out according to essence of the present invention, equivalent combinations.
