Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure is provided, and cost is low, and is easy to use, quantitatively accurately, and the continuous injector injection regulating mechanism that error is little.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of continuous injector injection regulating mechanism, it comprises sleeve, the core bar of band piston, it is characterized in that: sleeve rear end connects an interfix cover, the rear sleeve of core bar upper piston is equipped with regulates silk and back-moving spring, the back-moving spring that is sleeved on the core bar is limited in the through hole of regulating silk, regulate the silk rear portion and be provided with graduated scale, the front portion is provided with external screw thread, interfix cover inboard is provided with and regulates the female thread that silk is connected, the adjusting silk rotation in the interfix cover that has graduated scale is moved, regulate the range of activity of core bar in the sleeve cavity, realize the adjusting of injection volume.
The present invention regulates a tail end and is provided with the bulge loop that is used to rotate rotation adjusting silk, and the bulge loop appearance is axially arranged with anti-skidding striped.
Interfix of the present invention cover appearance rear portion is axially arranged with the capacity datum line, and it aligns with axial datum line of regulating silk high scale scale during use, accurately determine injection volume how much.The interfix cover also radially is provided with a hole, and a lock screw is installed.Interfix puts goes back suit one handle front handlebar.
The present invention is owing to have the adjusting silk of graduated scale at the outside suit one of core bar, sleeve rear end connects an interfix cover, regulating silk can move in the interfix cover in rotation, regulate the range of activity of core bar in the sleeve cavity, realize the adjusting of injection volume, against existing technologies, injection volume of the present invention is quantitative, easy to adjust, accurate, graduated scale is not easy to wear, and it is convenient to observe.Simple structure of the present invention, easy to use, quantitatively accurately, error is little, and is safe in utilization, reliable, prolonged the service life of syringe greatly, is a kind of ideal continuous injector injection regulating mechanism.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the cut-away view of Fig. 1;
1. core bar sleeves among the figure, 2. piston, 3. core bar, 4. the interfix cover is 5. regulated silk, 6. back-moving spring, 7. handle push rod, 8. lock screw, 9. handle front handlebar, 10. nut, 11. capacity datum lines, 12. graduated scales, 13. bulge loops.
The specific embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of continuous injector injection regulating mechanism, it comprises sleeve 1, piston 2, core bar 3, sleeve 1 front portion is provided with the medicinal liquid of band check valve and imports and exports, piston 2 is installed in core bar 3 front ends, and core bar 3 rear portions are provided with handle push rod 7, and piston 2, core bar 3 can move forward and backward along the cavity of sleeve 1, take out injection liquid, and inject continuously.The miscellaneous part and the prior art of above-mentioned composition structure and continuous injector for animals are basic identical, and this does not describe in detail.
Characteristics of the present invention are: sleeve 1 rear end connects interfix cover 4, and the rear sleeve of core bar 3 upper pistons 2 is equipped with regulates silk 5 and back-moving spring 6.Regulate silk 5 rear portions and be provided with graduated scale 12, the front portion is provided with external screw thread, and interfix is overlapped 4 inboards and is provided with and regulates silk 5 female threads that are connected, and that is to say that adjusting silk 5 and interfix cover 4 are by being threaded.Regulate silk 5 by rotation, the adjusting silk 5 that has graduated scale 12 can overlap in 4 in interfix and move forward and backward, and determines and the range of activity in sleeve 1 cavity such as adjusting core bar 3 and piston 2, realizes the adjusting of injection volume.
The present invention is sleeved on back-moving spring 6 on the core bar 3 and is limited in the through hole of regulating silk, and back-moving spring 6 its front ends withstand on the positive stop lug boss of regulating silk 5 front end inboards, and the rear end withstands on the positive stop lug boss on the core bar 3.Like this, it can help core bar 3 and piston 2 after having injected, and in time resets.
The present invention regulates silk 5 tail ends and is provided with the bulge loop 13 that is used to rotate rotation adjusting silk, and the bulge loop appearance is axially arranged with anti-skidding striped.Bulge loop 13 plays turning handle.
Interfix of the present invention is overlapped 4 appearance rear portions and is axially arranged with capacity datum line 11, and it aligns with axial datum line of regulating silk 5 high scale scales 12 during use, helps to define the scale of graduated scale 12, accurately determine injection volume what.Interfix cover 4 also radially is provided with a hole, and a lock screw 8 is installed.Spin locking screw 8 can hold out against the adjusting silk 5 in the interfix cover 4, locks it and no longer rotates mobilely, and injection volume is determined in the position of secured adjusted silk 5.
When the present invention uses, the artificial bulge loop 13 that rotates, drive adjusting silk 1 overlaps 4 internal rotation in interfix and moves, and the axial datum line of the graduated scale 12 at adjusting silk 5 rear portions is corresponding with the axial capacity datum line 11 that 4 appearance rear portions are overlapped in interfix, indicates the how little of injection volume.The range of activity of core bar and piston is determined in the set basis sleeve of graduated scale 12, and consistent with injection volume, determines the size of injection volume with this.The intravital capacity of pitch and chamber of regulating silk is proportional, regulates a moving week of silk revolution, and the intravital capacity in chamber can be regulated within the specific limits.Line aligns with line, and is easy and simple to handle, is convenient to observe, and is convenient to carry out exactly trace and regulates, and the capacity adjustment is accurate.
Go back suit one handle front handlebar 9 on the interfix cover 4 of the present invention, it is to be tightened on interfix cover 4 by nut 10.Handle front handlebar 9 cooperates with the handle push rod 7 of core bar 3 rear ends, is convenient to hold firmly, injects continuously.
