Abstract
The utility model relates to an interruptible injector able to adjust the injection dosing for livestock, which comprises a transfusion tube and a liquid box. The injector is arranged with a piston rod at the middle of the gripe, and a locking nut is used to integrate the gripe and the piston rod. The front end of the gripe is provided with a screw thread connecting regulator, the inner hole thereof has a step. Between the piston rod and gripe is an active telescopic cylinder, the tail thereof is arranged with a spring, making the telescopic cylinder against the step of the regulator. The front end of the telescopic cylinder is provided with a screw thread connected with a compaction ring, which is placed on the needle head at the top end of the telescopic cylinder. The compaction ring is provided with an ink ring. A retaining valve is installed at the top end of the piston rod and the top end of the inner side of the telescopic cylinder separately. The utility model overcomes shortcomings of prior products and provides veterinarians with a convenient bacterin injection device. With advantages of simple structure, strength saving, and easy carrying around, the utility model can make injection continuously, and the injection volume each time is the same as the previous one, thus enhancing the epidemic prevention effect of bacterin. The utility model is safe and reliable.
Description
Affiliated field
This utility model belongs to the appurtenance of veterinary medical instrument, especially relates to a kind of domestic animal and uses the adjustable uninterrupted syringe of injection volume.
Technical background
Vaccinating at present domestic animal, birds and beasts prevents epidemic or treatment, still utilize ordinary syringe to carry out, not only injection speed is slow, influenced work efficiency, and the amount that at every turn pushes is difficult for grasping, have influence on the epidemic prevention quality and the therapeutic effect of vaccine, when injecting for a large amount of birds and beasts, also will constantly extract medicinal liquid, use very inconvenient.Therefore market be sought after a kind of simple in structure, more laborsaving, can inject continuously and syringe that injection volume can be regulated.
Summary of the invention
The purpose of this utility model is: overcome the deficiency of present product, provide a kind of simple in structure, can carry medicinal liquid, injection volume can be regulated, and the syringe that can use continuously.
For achieving the above object, the following technical scheme of this novel employing: a kind of domestic animal is used the adjustable uninterrupted syringe of injection volume, it connects tube for transfusion and spray tank etc. by syringe and forms, piston rod is housed in the middle of the handle of syringe, the axle center of piston rod is porose, there is locking nut that handle and piston rod are fixed as one on the screw thread of afterbody, the front end of handle has the screwed connection actuator, the endoporus of actuator is given prominence to a step, in the centre of piston rod and handle active retracting cylinder is housed, the afterbody of retracting cylinder is equipped with spring, retracting cylinder is outwards withstood on the step of actuator, on the screw thread of retracting cylinder front end hold-down ring is housed, hold-down ring is pressed on the vertical syringe needle of retracting cylinder, at the top of piston rod the feed liquor check valve is housed, the fluid check valve is equipped with at the top of retracting cylinder inboard.
In order to prevent duplicate injection or leakage injection to domestic animal, the red ink paste used for seals ring is housed on hold-down ring, the color net of band dyestuff is housed in the groove of red ink paste used for seals ring.
The beneficial effects of the utility model are: for the veterinary provides a kind of convenient and practical vaccine injection equipment, can inject continuously, injection volume can be regulated as required, and the per injection amount is consistent.Simple in structure, laborsaving relatively, safe and reliable, improved the epidemic prevention effect of vaccine, can replace present needle tube type injecting method.

Fig. 2 is the structure cutaway view of syringe;
As shown in the figure: 1 syringe needle; 2 pin cutting edges of a knife or a sword; 3 color nets; 4 red ink paste used for seals rings; 5 hold-down rings; 6 actuators; Locking nut before 7; 8 handguards; 9 handles; 10 piston rods; 11 back locking nuts; 12 union joints; 13 springs; 14 retracting cylinders; 15 feed liquor check valves; 16 sealing rings; 17 cavity volumes; 18 fluid check valves; 19 scales; 20 braces; 21 spray tanks; 22 tube for transfusions; 23 steps.
Specific embodiments
Embodiment: Fig. 1 is its contour structures sketch map, Fig. 2 is the structure cutaway view of syringe, as can be seen from the figure, handle 9 is connected as a single entity with handguard 8, the front end of handle 9 has screwed connection actuator 6, the front end of actuator 6 has a step 23 to the inside, piston rod 10 is equipped with in the centre of handle 9, the afterbody of piston rod 10 is fixed as one handle 9 and piston rod 10 by back locking nut 11, the vertical periphery of piston rod 10 is carved with groove, sealing ring 16 is housed in the groove, feed liquor check valve 15 is equipped with in the inboard of piston rod part, and the centre of piston rod 10 is holes, and its afterbody is that union joint 12 connects tube for transfusion 22, the other end of tube for transfusion 22 links to each other with spray tank 21, has braces 20 to back on the body on the spray tank 21 and carries.In the centre of piston rod 10 and handle 9 active retracting cylinder 14 is housed, the afterbody of retracting cylinder 14 is equipped with spring 13, under the elastic force effect of spring 13, retracting cylinder 14 is outwards ejected, and withstands on the step 23 of actuator 6 inboards, and rotary actuator 6 steps 23 move forward and backward, be used for changing the length that retracting cylinder stretches out, thereby regulate the volume of cavity volume 17, preceding locking nut 7 is used for fixing actuator 6, and it can not moved voluntarily.Inside top at retracting cylinder 14 is equipped with fluid check valve 18, on the screw thread of retracting cylinder 14 front ends hold-down ring 5 is housed, hold-down ring 5 is pressed on the retracting cylinder 5 vertical syringe needles 1, on the screw thread of hold-down ring 5 front ends red ink paste used for seals ring 4 is housed, rotation red ink paste used for seals ring 4 red ink paste used for seals rings can move forward and backward, and in the groove on the preceding section of red ink paste used for seals ring 4 color net 3 are housed.
During use syringe needle 1 is contained in the top of retracting cylinder 14, screw on hold-down ring 5 and compress syringe needle 1, will inject colorant in the color net on the red ink paste used for seals ring 43, be spun on the top of retracting cylinder 14 again, the distance of regulating red ink paste used for seals ring front and back can change the length that pin cutting edge of a knife or a sword 2 stretches out, and is used for regulating the degree of depth of injection.Insert on the piston rod afterbody union joints 12 with tube for transfusion 22, the other end links to each other with medicine bottle in the spray tank 21.According to required injection volume rotary actuator 6, observe the scale 19 of handle front end simultaneously, adjust the back with preceding locking nut 7 with its locking.Hold the buttocks that handle thrusts pin cutting edge of a knife or a sword 2 domestic animal, stamp the marking behind the color net 3 contact buttocks, prevention is heavily annotated or is leaked and annotates, the elastic force that continues to advance retracting cylinder 14 to overcome spring 13 moves backward, the volume of cavity volume 17 is reduced, medicinal liquid in the cavity volume 17 injects in the tame carcass by fluid check valve 18 and syringe needle, up to piston rod 10 tops with till the inwall of retracting cylinder 14 front ends contacts, retracting cylinder 14 is ejected by spring 13 when extracting pin, medicinal liquid reenters in the cavity volume 17 through feed liquor check valve 15, for injection next time is got ready.Arrow is the mobile direction of medicinal liquid among the figure, because the distance that moves of retracting cylinder 14 changes according to the displacement of actuator 6, therefore this novel injection volume can be regulated, and regulates the each injection volume in back and be consistent.Because of gassy in pipeline and the cavity volume 17, should push away several retracting cylinders down earlier when bringing into use, inject again after medicinal liquid to be had is got.
