Specific embodiment
Below in conjunction with attached drawing, the above and other technical features and advantages of the present invention are carried out clearly and completely
Description, it is clear that described embodiment is only the section Example of the utility model, rather than whole embodiments.
In one embodiment, as shown in Figure 1.Present embodiments provide disposable syringe for veterinary use comprising syringe 1,
Push rod 2 and injection needle 3.Also, push rod 2 is set in syringe 1；3 sets of injection needle on syringe 1；The inner wall of syringe 1 is equipped with ring
Shape slot 11, opening 12 of the annular groove 11 close to syringe 1；The length of push rod 2 is less than the length of syringe 1, and the end 21 of push rod 2 is in circle
Sheet, the end 21 of push rod 2 are flexible piece, and 21 radius of end of push rod 2 is greater than the inner radial of syringe 1 and is less than annular groove
11 inner radial；Wherein, when push rod 2 is completely into arriving in syringe 1, the end 21 of push rod 2 is embedded in annular groove 11, makes to push away
Bar 2 is kept completely into the state arrived in syringe 1.
In the present embodiment, disposable syringe for veterinary use is in primary complete use process, need by push rod 2 completely into
Enter into syringe 1, so that the liquid medicine in syringe 1 be squeezed out.But since the end of push rod 2 21 in disc-shaped and is
Flexible piece.So the end 21 of push rod 2 is embedded in annular groove 11, and makes push rod when push rod 2 is completely into arriving in syringe 1
2 keep completely into the state arrived in syringe 1.At this time the end 21 of push rod 2 relative to the opening 12 of syringe 1 be in indent,
So can not extract.
In one embodiment, as shown in Figure 1.Disposable syringe for veterinary use is present embodiments provided, further includes needle body
External member 4；Needle body external member 4 is cylindrical in shape, and one end of needle body external member 4 provides injection needle 3 and is fixedly connected, and the other end of needle body external member 4 mentions
It is detachably connected for syringe 1.
In the present embodiment, injection needle 3 can be removed from syringe 1.It is realized particular by needle body external member 4.It is real
On border, needle body external member 4 is also common in current injector for medical purpose.
In one embodiment, needle body external member 4 is moulding.
In one embodiment, the end outer peripheral edge of syringe 1 is equipped with a circle external screw thread, and the inner peripheral of needle body external member 4 is equipped with
One circle internal screw thread, the other end of needle body external member 4 provide syringe 1 and are threadedly coupled.
In the present embodiment, only needle body external member 4 can be mounted on syringe 1 by one circle of rotation, very convenient.
In one embodiment, as shown in Figure 2.Disposable syringe for veterinary use is present embodiments provided, further includes rubber
First 5.Rubber end 5 is sheathed on the other end of push rod 2；Rubber end 5 include set gradually first annular raised 51, it is first annular
Groove 52, the second annular protrusion 53, second annular groove 54 and third annular protrusion 55.
In the present embodiment, push rod 2 is cooperated by setting Rubber end 5.Specifically, the Rubber end 5 in the present embodiment is special
Fixed, because it includes first annular raised 51 set gradually, first annular groove 52, the second annular protrusion 53, the second ring
Connected in star 54 and third annular protrusion 55.So there are very big deformation spaces on the length direction along push rod 2.
Especially spaced first annular groove 52 and second annular groove 54 provide the very big deformation space of Rubber end 5.
So after the liquid medicine in syringe 1 is squeezed out completely, push rod 2 is not completely into in syringe 1.And continue to exert a force, it can make
Push rod 2 is completely into in syringe 1, and the end 21 of push rod 2 is embedded in annular groove 11.So by the way that the present embodiment is arranged
In Rubber end 5, on the one hand the liquid medicine in syringe 1 can be squeezed out completely, on the other hand can be in the liquid in syringe 1
Drug is embedded in the end 21 of push rod 2 in annular groove 11.
In one embodiment, as shown in Figure 2.Rubber end 5 further includes buffer cavity (not shown)；Buffer cavity is set
In the first annular raised 51, inside of the second annular protrusion 53 and third annular protrusion 55, buffer cavity provides first annular
Raised 51, second annular protrusion 53 and third annular protrusion 55 buffer radially, and buffer cavity also provides first annular recessed
Slot 52 and second annular groove 54 buffer in the axial direction.
In the present embodiment, by the way that buffer cavity is arranged in the inside of Rubber end 5, injection effect can further be improved
And fixed effect, i.e., on the one hand the liquid medicine in syringe 1 can be squeezed out completely, it on the other hand can be in the liquid in syringe 1
Body drug is embedded in the end 21 of push rod 2 in annular groove 11.
In addition, in one embodiment, Rubber end 5 further includes buffer cavity (not shown), also, 5 face of Rubber end
It is less than Rubber end 5 backwards to the sidewall thickness of the end of push rod 2, the other end packet of push rod 2 to the sidewall thickness of the end of push rod 2
Include exhaust hole (not shown), the opening direction of exhaust hole and is perpendicularly oriented to rubber along the length direction of push rod 2
The side wall of first 5 ends towards push rod 2；Wherein, when Rubber end 5 is squeezed and broken, exhaust hole provides the gas in buffer cavity
The channel being discharged from the side backwards to injection needle 3.In the present embodiment, disposable syringe for veterinary use was once completely using
Cheng Zhong is needed push rod 2 completely into arriving in syringe 1, so that the liquid medicine in syringe 1 be squeezed out.And in the above process
It is middle to rack Rubber end 5, so that the syringe for veterinary use be made to can not be used again.Because the inside of Rubber end 5 has buffer cavity,
And need to apply certain power during squeezing push rod 2.So can be non-in the case where 5 sidewall thickness of Rubber end is different
It is often easy to rack the lesser side wall of thickness.And the air in buffer cavity is discharged from the side backwards to injection needle 3, avoids
The animal cured is had an impact.
Particular embodiments described above has carried out into one the purpose of this utility model, technical scheme and beneficial effects
The detailed description of step, it should be understood that the foregoing is merely specific embodiment of the utility model, be not used to limit this reality
With novel protection scope.Particularly point out, to those skilled in the art, it is all the spirit and principles of the utility model it
Any modification, equivalent substitution, improvement and etc. that are interior, being done, should be included within the scope of protection of this utility model.
