Description
Technical field
The utility model is related to experiment equipment fields, and in particular to a kind of Physiological Experiment sampler.
Background technology
Animal physiology is an experimental science, and Physiological Experiment is Physiological Teaching inalienable part.Physiology
It is mostly to be carried out with experimental animal to learn experimental study, using certain instrument and equipment and method, artificially controls certain
A little factors reproduce certain vital movement processes of animal bodies, or some sense organs are difficult to observe by inherent, rapid and micro-
The small vital movement that vary is reproduced, is recorded, convenient for people's observation, analysis and research.
In Physiological Experiment, it is sometimes desirable to be sampled to liquid preparation or drug, usually be adopted when sampling in the prior art
It is sampled with sampler such as suction pipe or trickle irrigation, after completing sampling, the liquid that sampler outer wall speckles with easily drips, may
External environment is polluted.
Utility model content
The purpose of this utility model is to provide a kind of Physiological Experiment samplers, external to solve liquid drippage pollution
The problem of environment.
In order to achieve the above objectives, the utility model adopts the following technical solution：
A kind of Physiological Experiment sampler, including mounting bracket and the locating rod being slidably arranged on mounting bracket, locating rod
It is equipped with sampling mechanism and removes liquid mechanism, sampling mechanism includes sampling head, collector tube, piston rod, piston and handle, and collector tube can
On the securing lever, sampling head is connected to the lower end of collector tube to dismantling connection, and piston is slidably arranged in collector tube, under piston rod
End is fixedly connected with the piston, upper end is fixedly connected with handle；Except liquid mechanism includes rack, shaft, gear and cam, rack is vertical
Be fixedly connected on the securing lever, shaft is rotatably connected on mounting bracket, and gear and cam are set in shaft, and cam and turn
Unilateral bearing is equipped between axis, unilateral bearing is in free state when shaft rotates forward, and cam is located at collector tube side.
The operation principle of this programme is：
Whole device when specifically used, is placed in splendid attire by installing component of the mounting bracket as sampling mechanism and except liquid mechanism
Have above the vial of liquid reagent or drug, sampling mechanism from vial for sampling, and in sampling mechanism, sampling head is used for
It stretches into liquid, handle is convenient for flexible piston rods, is moved in collector tube by piston rod band piston, works as piston upwards
When, collector tube is interior to generate negative pressure, draws liquid into collector tube, completes the sampling of liquid.Except liquid mechanism has been sampled for removing
At rear liquid collecting pipe outer wall residual liquid, except in liquid mechanism, since rack is fixedly connected with locating rod, rack is with locating rod
It moves and moves, when locating rod moves downward sampling, band carry-over bar moves downward, and rack drives gear rotates forward, and gear drives
Shaft rotates forward, and unilateral bearing is in free state at this time, and cam does not rotate；After the completion of sampling, locating rod moves upwards drive
Rack moves upwards, and the reversion of rack drives gear, the reversion of gear band turn axis, unilateral bearing is in locking state, cam at this time
As shaft rotates together, when cam rotates, collector tube is intermittently collided, it will be under residual liquid collision in liquid collecting pipe outer wall
Come.
Following technique effect can be reached using this programme：
1, after the completion of sampling, liquid collecting pipe outer wall residual liquid can be removed by removing liquid mechanism, residual liquid is avoided to drip
Fall pollution external environment.
2, except liquid mechanism except liquid process is when being moved upwards by locating rod, rack movement band moving gear and cam rotate
It realizes, is not necessarily to additional driving mechanism.
3, due to the presence of unilateral bearing, when locating rod moves downward sampling, cam can remain stationary as, after completing to sample
When locating rod moves upwards, cam just rotates and carries out collision collector tube, avoids cam rotation collision when locating rod moves downward
Collector tube influences liquid sampling.
4, collector tube is detachably connected in locating rod, is conveniently adjusted the vertical position of collector tube on the securing lever, and just
It is removed in by collector tube, carries out Bioexperiment.
Further, mounting bracket is equipped with the hydraulic cylinder for driving locating rod vertical and straight movement.It is positioned using Driven by Hydraulic Cylinder
Bar vertical and straight movement on mounting bracket can save artificial sliding locating rod, time saving and energy saving, and can be made using Driven by Hydraulic Cylinder locating rod
Locating rod movement is more steady.
Further, the top of liquid collecting pipe outer wall is fixed with rope, and the lower end of rope is fixed with buoyant spheres, buoyant spheres lower end with
Sampling head lower end flushes.Since the vial for containing liquid preparation or drug is often lighttight, visually it is difficult to judge to sample
Whether whether head stretches into liquid, can be tightened according to rope to judge whether sampling head stretches into liquid, if rope is in tighten
State is filled, shows that buoyant spheres are not up to liquid surface, is i.e. sampling head does not extend into liquid, if rope is in relaxed state, shows buoyancy
Ball has reached liquid surface, i.e. sampling head has stretched into liquid.
Further, liquid collecting pipe outer wall is equipped with scale.The amount of required liquid can be accurately taken out by reading scale.
Further, horizontal sliding is provided with extraction raffinate accumulator tank on mounting bracket, and bullet is connected between extraction raffinate accumulator tank and mounting bracket
Property part, extraction raffinate accumulator tank are fixedly connected with the first voussoir, and locating rod is fixedly connected with the second wedge coordinated with the first voussoir wedge surface
Block.
Further, track is fixedly connected on mounting bracket, extraction raffinate accumulator tank is slidably arranged in track.Track can be to extraction raffinate
Accumulator tank plays guiding role, and extraction raffinate accumulator tank is made to move more steady, and is avoided that when extraction raffinate accumulator tank moves and occurs partially
It moves.
