Description
Technical field
The utility model is related to mechanical manufacturing field, more particularly to a kind of medicine detection pipettor.
Background technology
In medical test, pipettor be it is a kind of by serum be transplanted on out of the test tube for having serum another added with
The invisible spectro instrument of reagent.Pipettor is conventional low capacity liquid transfer device, is widely used in hospital, big-and-middle universities and colleges
Laboratory, it has precision high, the features such as quick detachable.But the pipettor sold on the market at present, is generally employed same
Design, i.e. control button are placed at the top of pipettor, and control button is directly pressed by thumb, are so pressed control and are pressed
Button contact area is small, when prolonged experimental implementation, and the pressure for referring in particular to joint is larger, influences comfortableness.
Utility model content
The utility model purpose be in order to overcome the deficiencies in the prior art and provide it is a kind of it is reasonable in design, using comfortable, amount
The medicine detection pipettor that journey is adjustable, suction pipe is replaceable.
To reach above-mentioned purpose, the utility model employs following technical scheme.
A kind of medicine detection pipettor, including it is sliding tube, piston, push rod, connecting rod, adjustable plate, spring, draw ring, trapezoidal
Nut, screwed hole, threaded rod, trapezoidal groove, sleeve pipe, suction pipe and sealing ring, the piston are movably arranged in sliding tube；It is described
Piston upper surface is provided with push rod；Spring is symmetrically arranged between the piston and adjustable plate；The push rod is passed through after adjustable plate
Draw ring is connected with by connecting rod；The connecting rod is shaped as L-type；The center of the trapezoidal nut offers screwed hole；Institute
State adjustable plate two ends and be provided with threaded rod；The upper portion side wall of the sliding tube is symmetrically and evenly provided with trapezoidal groove；Institute
State the bottom opening position that sleeve pipe is arranged on the sliding tube；The suction pipe is arranged on the inside of sleeve pipe by sealing ring.
As further improvement of the utility model, the end of the trapezoidal nut is additionally provided with operation handle.
Due to the utilization of above-mentioned technical proposal, the advantageous effects that the utility model has：Technology of the present utility model
Scheme, can be by realizing to work by using piston, spring and adjustable plate is set in sliding tube to the conversion for adjusting Board position
The regulation of spring tension size between plug and adjustable plate, and then the regulation to pipettor maximum range is played, with structure letter
It is single, easy to adjust, use the wide advantageous effects of scope；The technical program on push rod also by setting connecting rod and drawing
Ring, it is possible to achieve on the basis of traditional top pressing operation, increases the mode of side locations pressing operations, is saved with operation
Power, the diversified advantageous effects of fatigue, mode of operation for reducing finger excessive operation；The technical program also using sleeve pipe and
The mode connected sucking pipe of sealing ring, with being conveniently replaceable cleaning, expand beneficial skill to the adaptability of the container of different-diameter
Art effect.
