Specific embodiment
The utility model is more fully understood for the ease of those skilled in the art, below by specific embodiment and in conjunction with attached drawing pair
The utility model is described further.
Herein, term " on ", "lower", "left", "right", "front", "rear" are all to make referring to attached drawing convenient for description
, it is not intended to limit the protection scope of the utility model.
As shown in Figure 1, a kind of fowl vaccine injection device, including inner cavity is columnar injection tube 10, before injection tube 10
End center is provided with the liquid outlet 15 communicated with its inner cavity, the common injection needle 16 of mountable connection on liquid outlet 15.Injection
The rear end opening of cylinder 10, and opening is equipped with detachable end 8 behind, is provided at the center of end cap 8 transparent back and forth
Guide hole (is not infused) in figure.The inlet 17 communicated with its inner cavity is provided in the underside of forward of injection tube 10, it can on inlet 17
Installation connects the liquid suction pipe 19 to take out medicine.Check valve I 14 is fixed in liquid outlet 15, the outlet of check valve I 14 is outside, from
And external fluid can not enter injection tube 10 through liquid outlet 15.Check valve II 18, check valve II are fixed in inlet 17
18 outlet is inside, so that the fluid of injection tube 10 can not be flowed out through inlet 17.Be equipped in the inner cavity of injection tube 10 and its
Coaxial piston 13, piston 13 can slide back and forth along the inner cavity of injection tube 10, and the inner cylinder of the outer rim of piston 13 and injection tube 10
Face is in sealing contact.Coaxial push rod 6 is removably installed in the rear end of piston 13, the rear end of push rod 6 backs through end
Lid 8 stretches out in outside injection tube 10, and the guide hole concentric gap on push rod 6 and end cap 8 cooperates.It is located in injection tube 10 in push rod 6
Shaft part on be arranged with compressed spring 11, the rear and front end of compressed spring 11 be respectively held against piston 13 rear end and end cap 8 it is interior
Side.It is machined with external screw thread on push rod 6, the limit being threadedly engaged with it is installed on the shaft part that push rod 6 is located at 8 outside of end cap
Position nut 7, stop nut 7, push rod 6 and injection tube 10 are made of the stainless steel of no magnetic conductivity.It is fixed on the inner face of end cap 8
There is the electromagnet 9 of coaxial annular, the armature 12 of coaxial annular, electromagnet 9 are fixed in the rear end of piston 13
The maximum outside diameter of compressed spring 11 is all larger than with the inner ring of 12 correspondence of armature and the two.It is solid on the downside of the rear portion of injection tube 10
Surely there is handle 3, the battery compartment 4 of lower part opening is provided in handle 3, be equipped in the lower end of handle 3 removably, to block
The battery cover 1 of 4 under shed of battery compartment.Battery 2 is installed in battery compartment 4, battery 2 and electromagnet 9 are passed through into conducting wire electricity
Connection, and switch 20 is in series on conducting wire between, so that the controllable electromagnet 9 of switch 20 obtains electric power loss, switch 20
