Abstract
The invention discloses a syringe putter with an o-type ring rubber plug. The syringe putter includes the o-type ring rubber plug (1) and a putter body (2); the lower portion of the putter body (2) is provided with a pressing handle (21), the upper portion of the putter body (2) is provided with a putter head (22), and a push-pull ring (221) is formed on the putter head (22). The syringe putter is characterized in that the push-pull ring (221) is provided with a groove (222) used for installing the o-type ring rubber plug (1), and the groove (222) is located in the middle of the push-pull ring (221). The syringe putter is easy to push and pull, good in sealing performance, low in manufacturing cost and safer to use.
Description
Technical field
The present invention relates to injector push-rod, relate in particular to a kind of injector push-rod with zero type circle plug.
Background technology
The plug that existing injector push-rod front end is installed, comprise that rubber plug body reaches for connecting the cavity of injector push-rod, plug and push rod are interference fit, great majority are rubber plug body and are provided with the two seals ring structure, be top edge and feather edge two seals ring, the arc radius at this structure plug sealing ring ring point place is larger, the angle of sealing ring ring point is because of demoulding difficulty, make the angle that is greater than 90 degree, protrude not obvious, cause push rod push-and-pull frictional resistance large, because the poor flexibility of material causes the problems such as poor sealing
And plug and medicinal liquid contact area are large, can cause certain pollution to medicinal liquid.
Summary of the invention
Technical problem to be solved by this invention is: a kind of injector push-rod with zero type circle plug is provided, and this push rod push-and-pull is light, good airproof performance, and low cost of manufacture, safer.
In order to solve the problems of the technologies described above, the present invention is by the following technical solutions: with the injector push-rod of zero type circle plug, comprise zero type circle plug and push rod body, push rod body bottom is provided with presses hands, push rod body top is provided with push rod cup, molding push-pull ring on push rod cup is characterized in that: described push-pull ring is provided with the groove that zero type circle plug is installed, and this groove is positioned at the centre position with push-pull ring.
Wherein, the diameter of described push-pull ring is slightly less than the injector cartridge internal diameter.
Wherein, the end face of described push-pull ring is plane or is curved surface, should consider from the residual quantity that reduces injection as far as possible, depending on the injector cartridge end shape, determines.
Wherein, described groove is square or for arc, the internal diameter of groove equals zero type circle internal diameter, and the width of groove equals zero type astragal footpath, and the degree of depth of groove is slightly larger than half of zero type astragal footpath.
In order to solve the problems of the technologies described above, the present invention also adopts following further technical scheme: described zero type circle plug is made by medical plastic or medical grade rubber material.
From above technical scheme: 1, zero type circle plug be arranged on the distortion that contact generation afterwards in groove with the injector cartridge inwall can only be within the groove scope, therefore this zero type circle plug is propped up by push-pull ring, without very strong elasticity, just can play stronger sealing function; 2, the radius of the ring of zero type circle plug point circular arc is less, the angle that encircles sharp dual-side is less than 90 °, zero type circle plug like this protrudes obviously, further strengthened sealing property, and the contact surface less with the injector cartridge inwall, correspondingly and the frictional resistance between simplified inwall less, make the push rod push-and-pull light; 3, this zero type circle plug adopts the medical grade plastic materials injection moulding, solves because poor flexibility causes syringe and the problem of leaking occurs; 4, zero type circle plug is simple in structure, has reduced the cost of raw material of making plug; 5, zero type circle plug and medicinal liquid contact area are very little, and plug is greatly reduced the pollution of medicinal liquid, and product is safer.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the partial enlarged view of Fig. 1.
In figure: 1 zero type circle plugs, 2 push rod bodies, 21 press hands, 22 push rod cups, 221 push-pull rings, 222 grooves, A push-pull ring end face, d push-pull ring diameter, d1 zero type circle internal diameter, d2 zero type astragal footpath.
The specific embodiment
As shown in Figure 1, 2, comprise zero type circle plug 1 and push rod body 2, push rod body 2 bottoms are provided with presses hands 21, push rod body 2 tops are provided with push rod cup 22, molding push-pull ring 221 on push rod cup 22, it is characterized in that: described push-pull ring 221 is provided with the groove 222 that zero type circle plug 1 is installed, and this groove 222 is positioned at the centre position of push-pull ring 221.
Wherein, described push-pull ring 221 diameter d are slightly less than the injector cartridge internal diameter.
Wherein, the end face A of described push-pull ring 221 is plane or is curved surface, determines depending on the injector cartridge end shape.
Wherein, described groove 222 is square or for arc, the internal diameter of groove 222 equals the inner diameter d 1 of zero type circle plug 1, and the width of groove 222 equals the wire diameter d2 of zero type circle plug 1, and the degree of depth of groove 222 is slightly larger than half of wire diameter d2 of zero type circle plug 1.
Wherein, described zero type circle plug 1 is made by medical plastic or medical grade rubber material.
Above-mentioned used for illustrative purposes only, and be not limitation of the present invention, those skilled in the art, in the situation that do not break away from the spirit and scope of invention, various variations and modification also belong to category of the present invention.
