Abstract
The utility model discloses a novel low-resistance injection syringe rubber plug which comprises a conical plug cap and a columnar connecting cover. The maximum diameter of the conical plug cap is larger than the diameter of the columnar connecting cover. A telescopic sleeve is arranged between the conical plug cap and the columnar connecting cover. A sealing ring is arranged on the sleeve in a sleeved mode. According to the novel low-resistance injection syringe rubber plug, due to the fact that the telescopic sleeve is arranged between the conical plug cap and the columnar connecting cover, when a core bar of an injection syringe is pushed, the sleeve contracts; and when the core bar of the injection syringe is pulled, the sleeve stretches. Therefore, the resistance in the pushing process or the pulling process of the core bar is greatly reduced, and the sealing effect is better.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of plug of novel low-resistance injector.
Background technology
Disposable syringe is normally by plastic cylindrical shell and core bar, form as three parts of plug of glue system, and the workman is enclosed within plug the head of core bar earlier, grips core bar then and plug is filled in the inner chamber of cylindrical shell, has just formed a syringe.
The tradition plug is made up of the top tapered cock cap that is connected as a single entity and bottom cylindricality cavity, the base diameter of taper cock cap is greater than the diameter of cylindricality cavity, and respectively be processed with the bulge loop of the equal diameters of overall diameter and top tapered cock cap with the bottom at the middle part of cylinder chamber body sidewall, like this because the external diameter (being the base diameter of taper cock cap) of plug is bigger than the internal diameter of cylindrical shell, this interference fit that just relies on syringe realizes sealing, spur core bar back and forth, can drive plug and slide at cylinder inner surface, thereby realization is extracted and the purpose of force feed fluid.
The sealing that this interference fit between tradition plug and the cylindrical shell realizes is a kind of typical static sealing, and the external diameter that will lean on plug fully could be realized than the big certain amount of internal diameter of cylindrical shell.The magnitude of interference is little, and sealing can be leaked during syringe work just most likely; The magnitude of interference is big, although used lubricant, it is heavy that core bar promotes to feel, resistance is big.Therefore, this plug of static sealing that leans on fully should guarantee to seal reliably, promote again the little contradiction of resistance with regard to existing.
The utility model content
The technical problem that this utility model mainly solves provides the unique novelty of a kind of moulding, promotes the plug of the novel low-resistance injector that resistance is little, sealing effectiveness is excellent.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: the plug that a kind of novel low-resistance injector is provided, comprise taper cock cap and cylindricality adapter sleeve, the maximum gauge of described taper cock cap is greater than the diameter of cylindricality adapter sleeve, be provided with telescopic sleeve between described taper cock cap and the cylindricality adapter sleeve, be arranged with sealing ring on the described sleeve.
In preferred embodiment of this utility model, the diameter of described sealing ring upper surface is greater than the maximum gauge of taper cock cap, and the diameter of described sealing ring lower surface is identical with the diameter of cylindricality adapter sleeve.
In preferred embodiment of this utility model, the face of tiltedly carving is formed on described taper cock cap bottom, and described sealing ring upper end is provided with the described face of tiltedly carving carves the groove that closes.
In preferred embodiment of this utility model, described sealing ring is slidingly connected along sleeve.
The beneficial effects of the utility model are: the plug of this novel low-resistance injector is owing to be provided with telescopic sleeve between taper cock cap and cylindricality adapter sleeve, when the core bar of pushing syringe, sleeve shortens, when spurring the core bar of syringe, the sleeve elongation, resistance when having reduced promotion or pulling core bar widely, and sealing effectiveness is more excellent.
Description of drawings
Structural representation when Fig. 1 is the plug pulling core bar of this utility model novel low-resistance injector;
Fig. 2 is the structural representation of the plug of this utility model novel low-resistance injector when promoting core bar;
The labelling of each parts is as follows in the accompanying drawing: 1, taper cock cap, 2, the cylindricality adapter sleeve, 3, sleeve, 4, sealing ring, 5, tiltedly carve face.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1 and Fig. 2, this utility model embodiment comprises:
A kind of plug of novel low-resistance injector, comprise taper cock cap 1 and cylindricality adapter sleeve 2, the maximum gauge of described taper cock cap 1 is provided with telescopic sleeve 3 greater than the diameter of cylindricality adapter sleeve 2 between described taper cock cap 1 and the cylindricality adapter sleeve 2, be arranged with sealing ring 4 on the described sleeve 3.
The diameter of described sealing ring 4 upper surfaces is greater than the maximum gauge of taper cock cap 1, the diameter of described sealing ring 4 lower surfaces is identical with the diameter of cylindricality adapter sleeve 2, sealing circle 4 is less with the inwall contact surface of syringe, and frictional force between the two is less, and can not influence sealing effectiveness.
Described taper cock cap 1 bottom forms and tiltedly carves face 5, and described sealing ring 4 upper ends are provided with the described face 5 of tiltedly carving and carve the groove that closes.When the core bar of pushing syringe, tiltedly carving face 5 can be so that conical plug medicated cap 1 closely cooperates with sealing ring 4, and sealing effectiveness is better.
Described sealing ring 4 is slidingly connected along sleeve 3, and when spurring the core bar of syringe, sealing ring 4 can slide along sleeve 3, reduce the frictional force between sealing ring 4 and the sleeve 3.
During use, the plug of this novel low-resistance injector is fixed on the core bar end of injection, and pushes in the injector cartridge.When promoting core bar because the resistance between taper cock cap 1 and the injector cartridge inwall, sleeve 3 contraction in lengths, then sealing ring 4 two ends respectively with taper cock cap 1, cylindricality adapter sleeve 2 against (as shown in Figure 2), can promote core bar very like a cork; When the pulling core bar, since the resistance between taper cock cap 1 and the injector cartridge inwall, the elongation of sleeve 3 length, and then sealing ring 4 two ends form space (as shown in Figure 1) with taper cock cap 4, cylindricality adapter sleeve 2 respectively, can spur core bar very like a cork.
Compared with prior art, the plug of this novel low-resistance injector is owing to be provided with telescopic sleeve 3 between taper cock cap 1 and cylindricality adapter sleeve 2, when the core bar of pushing syringe, sleeve 3 shortens, when spurring the core bar of syringe, sleeve 3 elongations, the resistance when having reduced promotion or pulling core bar widely, and sealing effectiveness is more excellent.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes this utility model description and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
