Description
Technical field
This utility model is related to syringe, more particularly, to a kind of two-piece-dress self-destruction syringe, belongs to Dispoable medical consumption
Material field.
Background technology
It is known that the rubber piston of syringe has elasticity, it is a kind of preferable piston airtight material, can be effective
Prevent gas leakage and the leakage of piston.But, the high-volume that will adapt to automatic assembling production line (machine) quick produces it is necessary to will be miscellaneous
Disorderly unordered rubber piston mouth arranges in one direction in order, could insert in rubber piston by plastic push-rod, this is just to certainly
Dynamicization assembly line proposes extra requirement, thus increased being designed and manufactured as this, in addition, self-distruction structure is also required to try one's best
Simplify it is easy to manufacturing and assembling.
The applicant, through research and development for many years, designs " the type self-destroyed injection of two-piece-dress not needing to increase any spare and accessory parts newly
The device " (patent No.: 201320446664.1), production cost can be made substantially to reduce.We have found that through practice and declared
When the push rod drawing liquid of two-piece-dress self-destruction syringe product is pulled to maximum capacity, push rod hangs down toward breaking a cross blade being located
Nogata is broken and is a little easily broken off to when swinging, and there is the risk of self-destruction in advance；If waving during push rod push-and-pull or existing with cylinder
Certain angle, then there may be the risk of leakage at zero type circle plug and cylinder inboard wall sealing.
Content of the invention
The purpose of this utility model is: provides a kind of two-piece-dress self-destruction syringe, simplifies the knot of syringe further
Structure simultaneously ensures safety in utilization, reduces production cost, is more suitable for the large batch of quick production of automatic assembling production line (machine), subtracts
The percent defective of few product.
Technical solution of the present utility model is: this two-piece-dress self-destruction syringe includes hollow outer body and in cylinder
The internal push rod sliding, is characterized in that: 6:100(Rule of described cylinder) cone joint inner chamber front port molding card neck, described
Push rod front end sets injection all-in-one-piece elastic clamping hook and monocyclic layer plastic piston, and push rod is connected by breaking device for two sections using in front and back
Design and integrated injection molding, push rod position setting centring ring corresponding to nozzle during maximal dose for the push rod drawing liquid is to ensure to push away
Bar leading portion horizontal linear in cylinder runs up and down, and centring ring bottom sets cross convex bracing frame, and the top of push rod back segment is provided with
Recessed bracing frame, the coaxial symmetrical blading of push rod respectively be arranged in parallel two and breaks a little, and convex bracing frame is located in recessed bracing frame through four
Individual break an injection and connect into Integer push rod.
Wherein, another kind of technical scheme of described breaking device: push rod leading portion and back segment draw breakpoint joint by, draw
Breakpoint setup is on the axle center of push rod centring ring bottom surface.
Economic benefit of the present utility model is: using the monocyclic layer plastic piston of push rod integrated injection molding disjunctor, saves system
Make rubber piston, and make the design of automatic assembling production line (machine) and produce simpler, note during assembling, can be reduced further
The percent defective of emitter, reaches the quick requirement producing of high-volume, and the syringe classification medical waste after use can circulate profit again
With producing regenerated plastics, become Green Product.

In figure: 1 cylinder, 2 push rods, 11 card necks, 21 elastic clamping hooks, 22 monocyclic layers of plastic piston, 23 centring rings, 24
Break a little, the convex bracing frame of 2a, the recessed bracing frame of 2b.
Specific embodiment
For ease of understanding, referring to the drawings, embodiment of the present utility model is described in further detail.
As shown in Fig. 1～8, this two-piece-dress self-destruction syringe include hollow outer body 1 and in cylinder slide push away
Bar 2, is characterized in that: 6:100(Rule of described cylinder 1) cone joint inner chamber front port molding card neck 11, described push rod 2 front end
If injection all-in-one-piece elastic clamping hook 21 and monocyclic layer plastic piston 22, push rod 2 is set by breaking device connection for two sections using in front and back
Meter and integrated injection molding, when push rod 2 drawing liquid is to maximal dose, the push rod position setting centring ring 23 corresponding to nozzle is to protect
Card push rod leading portion horizontal linear in cylinder runs up and down, and centring ring 23 bottom is provided with cross convex bracing frame 2a, push rod back segment
Top be provided with recessed bracing frame 2b, the coaxial symmetrical blading of push rod respectively be arranged in parallel two and breaks a little 24, convex bracing frame 2a
Break a little 24 injections through four in recessed bracing frame 2b and connect into Integer push rod 2.
As shown in Figure 2,4, another kind of technical scheme of self-destructor: push rod leading portion and back segment break a little 24 company by
Connect, break and be a little arranged on push rod centring ring 23 bottom surface axle center.
As shown in Figure 1, 2, when push rod 2 of pulling back carries out drawing liquid, the inner chamber of cylinder 1 forms negative pressure, and external atmosphere pressure is oppressed
The edge of monocyclic layer plastic piston 22, make monocyclic layer plastic piston 22 be close to cylinder 1 inwall it is ensured that monocyclic layer plastic piston 22 not
Gas leakage.
As shown in Figure 7,8, when pushing away liquid in push rod 2 is to cylinder 1 and finish, after elastic clamping hook 21 elastic deformation of push rod front end
Through female Luer port card neck 11, card neck 11 will stop restorable elastic clamping hook 21 from retreating, and push rod 2 is locked, push rod 2
Backward during withdrawing, connection is broken and a little 24 is pulled off, and push rod leading portion is left in cylinder 1, and push rod back segment is drawn out rear push-rod 2 self-destruction
Cannot reuse.
Above-mentioned only for illustration of the utility model, and be not limitation of the utility model, the technology of the art
