Description

Veterinary syringe

Technical Field

The utility model relates to an injector, in particular to a veterinary injector.

Background

The structure of the veterinary syringe in the prior art generally comprises a syringe main body consisting of an injection head, a needle cylinder, a piston, a handle and the like, wherein a liquid suction joint is arranged on the outer side of the injection head of the syringe main body, the radial distance between the liquid suction joint and the injection head is longer, so that the liquid suction stroke is longer, and when the sucked liquid is less, the liquid is not easy to suck.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks of the prior art, the present invention is directed to: provides a syringe for animals which can shorten the liquid suction stroke.

The technical solution of the utility model is that: the utility model provides a veterinary syringe, includes the syringe main part, and the front end of syringe main part is equipped with the injection head, and the injection head outside is equipped with the imbibition joint, the outside of injection head has the recess of indent, and the tank bottom of recess is equipped with the screw hole with the inside intercommunication of injection head, the tip card that the imbibition connects is gone into in the recess, and is equipped with the packing ring between imbibition joint and the injection head, and the tip that the imbibition connects has the screw thread portion in the screw in screw hole.

Further, the threaded hole is arranged in the middle of the bottom of the groove.

Further, the groove is formed in the bottom of the injection head, the top end of the liquid suction joint is clamped into the groove, and the threaded portion of the top end of the liquid suction joint is screwed into the threaded hole.

Further, the gasket is placed at the groove bottom of the groove, the gasket is sleeved outside the threaded portion, and the top end of the liquid suction joint presses the gasket.

Use the utility model provides a veterinary syringe, its beneficial effect is: the outside of injection head has the recess of indent, and the tip card of imbibition joint is in the recess, can shorten the radial distance between injection head and imbibition joint, has shortened the imbibition stroke, can absorb more liquid.

Detailed Description

For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:

as shown in fig. 1-3, a syringe for animals comprises a syringe main body 1, an injection head 2 is arranged at the front end of the syringe main body 1, a suction joint 3 is arranged on the outer side of the injection head 2, a spring 5 and a steel ball 6 are arranged in the suction joint 3, an inner concave groove 21 is arranged on the outer side of the injection head 2, a threaded hole 22 communicated with the inside of the injection head 2 is arranged at the bottom of the groove 21, the end part of the suction joint 3 is clamped in the groove 21, a gasket 4 is arranged between the suction joint 3 and the injection head 2, and a threaded part 31 screwed into the threaded hole 22 is arranged at the end part of the suction joint 3.

The threaded hole 22 is provided in the middle of the bottom of the groove 21, and the threaded portion 31 is located in the middle of the suction fitting 3, so that the threaded portion 31 of the suction fitting 3 can be screwed into the threaded hole 22.

As a preferred embodiment of the present invention, the groove 21 is provided at the bottom of the injection head 2, the top end of the suction adapter 3 is engaged into the groove 21, and the screw portion 31 at the top end of the suction adapter 3 is screwed into the screw hole 22.

Of course, the recess 21 may be provided on the top of the injection head 2 as an alternative embodiment.

The gasket 4 is placed at the bottom of the groove 21, the gasket 4 is sleeved outside the threaded part 31, the top end of the liquid suction joint 3 presses the gasket 4, and the gasket 4 plays a sealing effect and prevents liquid from leaking.

As shown in figure 3, the piston 8 sleeved on the piston rod 7 of the injector body 1 is tightly attached to the needle cylinder 9, an O-shaped ring is not used, and the resistance generated when the O-shaped ring is used is omitted, so that the resistance applied when the injector is used is reduced, the injector is more smooth in pushing and pulling, and the scale control on the micro-dosage is more stable.

The utility model provides a veterinary syringe, the outside of injection head 2 has the recess 21 of indent, and the tip card that the imbibition connects 3 is gone into in recess 21, can shorten the radial distance between injection head 2 and imbibition joint 3, has shortened the imbibition stroke, can absorb more liquid.

It is to be understood that the foregoing is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, which is defined by the following claims and drawings.
