Abstract
The utility model relates to a device for adjusting the injection capacity of a continuous injector; wherein, a positioning cap and an adjusting wire are arranged at the rear end of the chip pole; and the adjusting wire is provided with an external cover with a ruler and a tail adjusting cap outside. The external cover and the positioning cap are connected and fixed together. The tail adjusting cap and the adjusting wire are connected and fixed together. Due to the external cover with the ruler, when applied, the utility model can not rotate with the adjusting wire, so that the ruler can be observed conveniently, and the positioning is accurate with small errors. The utility model has simple structure, low cost and convenient operation.
Description
Technical field
This utility model relates to a kind of veterinary medical instrument, a kind of specifically continuous injector injection regulating mechanism.
Background technology
We know that at present, the continuous injector for animals on the market is mainly connected to form by liquid storage medicine bottle, injection mechanism, entry needle headstock and a three-way valve assemblies.Injection mechanism comprises handle type connecting rod, sleeve, piston, core bar, back-moving spring, and the core bar rear end is provided with by positioning cap and regulates the adjusting device that silk constitutes, and regulates silk and is provided with graduated scale, is used for regulating injection volume, carries out quantitatively injection continuously.Graduated scale is set directly to be regulated on the silk, rotates and rotates along with regulating silk during use, observe inconvenient, quantitatively also inaccurate, error is big.The continuous injector that also has adopts transparent sleeve, and graduated scale is set directly on the sleeve, quantitatively regulate during use and the capacity observation is separately carried out, inconvenience is quantitatively also inaccurate, error is big.
Summary of the invention
Technical problem to be solved in the utility model 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 in the invention for solving the above technical problem is: a kind of continuous injector injection regulating mechanism, it is provided with positioning cap and regulates silk in the core bar rear end, it is characterized in that: regulate the outside overcoat and the tail end that have scale of being provided with of silk and regulate medicated cap, overcoat and positioning cap are connected and fixed, and tail end is regulated medicated cap and regulated silk and is connected and fixed.
This utility model is owing to regulate that silk is outside to be provided with the overcoat that has scale, and against existing technologies, it does not rotate with regulating silk during use, and it is convenient to observe scale, and is quantitatively accurate, error is little.This utility model simple structure, cost is low, and is easy to use.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of a kind of embodiment of this utility model.
1. regulate silk among the figure, 2. positioning cap, 3. overcoat, 4. tail end adjusting medicated cap, 5. scale, 6. graduation mark, 7. locking silk, 8. core bar, 9. sleeve.
The specific embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of continuous injector injection regulating mechanism, it is provided with positioning cap 2 and regulates silk 1 in core bar 8 rear ends, regulating silk 1 is connected with core bar and piston, relative position by threaded adjusting positioning cap 2 and adjusting silk 1, be used for regulating, the range of activity of control piston in sleeve 9, and then be used for regulating injection volume, carry out quantitatively injection 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 utility model are: adjusting 1 outside is provided with the overcoat 3 and the tail end that have scale 5 and regulates medicated cap 4, and overcoat 3 is connected and fixed with positioning cap 2, and tail end is regulated medicated cap 4 and is connected and fixed with adjusting silk 1.Tail end is regulated medicated cap 4 and is driven when regulating silk 1 rotation, is fastened on the scale 5 of overcoat 3, and the upper sideline that tail end is regulated medicated cap 4 is corresponding with scale 5, indicates the how little of injection volume.On the overcoat 3 in the set basis sleeve of scale 5 range of activity of piston determine, and and injection volume consistent, determine the size of injection volume with this.The intravital capacity of pitch and chamber of regulating silk 1 is proportional, regulates a moving week of silk revolution, and the intravital capacity in chamber can be regulated within the specific limits, has the overcoat 3 of scale 5, and it does not rotate with regulating silk 1 during use, and it is convenient to observe scale.The rotation of regulating silk 1 realizes by tail end adjusting medicated cap 4, tail end is regulated on the medicated cap 4 and also is axially arranged with a graduation mark 6, it can align with the axial line of scale 5 during use, the scale of scale 5 on the overcoat is defined in help, be convenient to carry out exactly trace and regulate, line aligns with line, and is easy and simple to handle, be convenient to observe, the capacity adjustment is accurate.
This utility model also is provided with locking silk 7 in positioning cap 2 outsides, quantitatively be used for lock adjustment silk 1 after accurately, and it is not rotated, and stably determines continuous injection volume.
Claims (3)
1. continuous injector injection regulating mechanism, it is provided with positioning cap and regulates silk in the core bar rear end, it is characterized in that: regulate the outside overcoat and the tail end that have scale of being provided with of silk and regulate medicated cap, overcoat and positioning cap are connected and fixed, and tail end is regulated medicated cap and regulated silk and is connected and fixed.
2. continuous injector injection regulating mechanism according to claim 1 is characterized in that: tail end is regulated on the medicated cap and is axially arranged with a graduation mark.
