Abstract
The invention relates to an animal injector, which relates to an injector. The animal injector comprises a pipe body, a piston, a piston push rod connected with the piston and a regulating nut, wherein the piston push rod is provided with threads; and the regulating nut is connected with the piston push rod through the threads. In the animal injector, the regulating nut capable of making axial motion along the push rod is arranged on the piston push rod; compared with the initial extraction quantity, the position of the regulating nut is calculated accurately according to a design dosage; and thus after the regulating nut is put in place, and when the injector is pushed manually, the situation of excessive or insufficient pushing due to large pushing force of animal injection does not occur. In addition, liquor amount injected every time can be controlled during mass injection.
Description
Technical field
The present invention relates to a kind of syringe, relate in particular to a kind of animal and veterinary quantitative injection device of syringe.
Background technology
In the animal and veterinary field, usually need to the domestic animal liquid medicine injection.The intramuscular injection of domestic animal need be than the thrust of great dynamics during liquid medicine injection; Under the bigger situation of thrust, be not easy the injection volume of accurate measurement medicinal liquid.The injection volume of medicinal liquid is of crucial importance for domestic animal, has error will influence the effect of treatment, epidemic prevention slightly.At present, also be useful on the scale of metering on the general syringe, when pushing, the medicinal liquid according to extracting reads an initial scale value, then, according to set amount, pushes.But because when injecting on the animal health, propelling movement power is big, during propelling movement, staff is not easy to control propelling movement power, and it is excessive to push slightly accidentally; Perhaps when in enormous quantities injection, per injection all needs artificial monitor closely injection volume, careless slightly also can cause push excessive or not enough.
Summary of the invention
The present invention is directed to above technical problem, a kind of restriction push rod stroke is provided, and then realize the accurately animal injector of control of propelling movement amount.
Technical scheme of the present invention is: comprise body, piston and the piston push rod that is connected as a single entity with piston, it also comprises adjusting nut, and described piston push rod is provided with screw thread, and described adjusting nut and described piston push rod are by being threaded.
The cross section of described piston push rod is a cross, is provided with the thread of some formation screw threads at the cross edge, and described adjusting nut and described thread are complementary.
Described piston push rod is provided with scale.
The present invention is provided with one on piston push rod can be along the adjusting nut of push rod axially-movable, and contrast initial draw amount should the throwing amount according to design, accurately calculates adjusting nut and where should be in; After adjusting nut puts in place, when manually pushing, can be not big because of the propelling movement power of animal injection, cause the excessive or insufficient situation that pushes.In addition, when injection in enormous quantities, also be convenient to control the amount of liquid medicine of per injection.

The specific embodiment
The present invention comprises body 4, piston 3 and the piston push rod 6 that is connected as a single entity with piston 3 as shown in Figure 1, 2, and it comprises that also adjusting nut 9,6 piston push rods are provided with screw thread, and adjusting nut 9 and piston push rod 6 are by being threaded.
The cross section of piston push rod 6 is a cross, is provided with the thread 7 of some formation screw threads at the cross edge, and adjusting nut 9 is complementary with thread 7.
Piston push rod 6 is provided with scale 5.
When using, the present invention shown in Fig. 3,4, from opening blanking cover 1, extracts a certain amount of (surpass should throwing amount) additive from importing and exporting 2.Although push away air in the body 4, collude the position of the corresponding scale 5 in piece 8 outer faces according to the mouth of pipe and read initial value; Then,, calculate adjusting nut 9 and where should be in, accurately put in place with reference to scale 5 according to setting injection volume.At last, push, no matter medicinal liquid what, the animal muscle injection resistance in the body 4 is much, manually all can push as possible, and the postpone that puts in place stops propelling movement naturally, and it is excessive not worry pushing.
Claims (3)
1. animal injector, comprise body, piston and with the piston push rod that piston is connected as a single entity, it is characterized in that it also comprises adjusting nut, described piston push rod is provided with screw thread, described adjusting nut and described piston push rod are by being threaded.
2. a kind of animal injector according to claim 1 is characterized in that, the cross section of described piston push rod is a cross, is provided with the thread of some formation screw threads at the cross edge, and described adjusting nut and described thread are complementary.
