Description
Technical field
The utility model relates to a kind of ultra-fine piston type liquid quantitative sampling device, and multi-purpose medical control laboratory sampling thief specifically is applied to check, the laboratory of medical domain biochemical analysis.
Background technology
Sampling thief shortcoming of the prior art is a utensil can only take or add a range after adjusting a liquid, can not take or add a plurality of ranges accurately and rapidly, as ultra micro quantitative liquids such as 5 microlitres, 10 microlitres, 15 microlitres, 20 microlitres, therefore, when needing to take in the check of carrying out a biochemical analysis or the experiment or adding the liquid of multiple different ranges, just need many or complete above-mentioned existing utensil, the manufacturing cost that is utensil is higher, and increases adjustment time and Operating Complexity.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, multi-purpose medical control laboratory sampling thief is provided, the technical scheme that its technical matters that solves the utility model adopts is: comprise the liquid storage plastic tube, suction nozzle, piston cylinder, piston rod, the piston sheath, nut, back-moving spring A, sleeve pipe, last item, screw, back-moving spring B, swivel nut, spline housing, button, range scale, it is characterized in that this device is mainly by piston cylinder, piston rod, back-moving spring A, back-moving spring B, last item and sleeve pipe are formed, be provided with button topmost, the lower end of button center is provided with last item, last item is a splined shaft, the last item lower end is provided with back-moving spring A, between last item and sleeve pipe, a spline housing that matches with last item is set, the periphery of spline housing is a swivel nut, back-moving spring B is connected with spline housing by screw, be provided with piston cylinder in the piston sheath, piston cylinder is provided with range scale, the lower end of piston cylinder is provided with suction nozzle, the lower end of suction nozzle is provided with the liquid storage plastic tube, sphere is arranged in liquid storage plastic tube upper end, and the piston sheath is connected with sleeve pipe by nut.
Principle of work: the utility model is mainly by piston cylinder, the piston rod of ultra-fine piston and disjunctor, its rear end of supporting between piston cylinder and the piston rod and back-moving spring and propelling piston bar is made up of the last item of button and a backup rolls and sleeve pipe, last item is a splined shaft, its axle is gone up each key length difference, can arrange by arithmetic progression, wherein the longest axle key height is less than the height of other each key, for the ease of processing and assembling, between last item and sleeve pipe, a spacing spline housing that cooperates with the last item of spline shaft type is arranged, the degree of depth that a keyway is arranged in its splined hole is less than other each keyway degree of depth, this shallow keyway is to be used for limiting other each axle keys except that the longest short axle key on the last item, to reach the difference location purpose of last item.Range shows accurately in order to make, compact conformation and proof strength, and piston cylinder can adopt to have transparent material such as glass or the plastics etc. that range scale shows and make, and is contained in the circular piston cylinder sheath, adopts between piston cylinder sheath and the sleeve pipe to be threaded.For the ease of processing and assembling, between spline housing and sleeve pipe, be provided with one cooperates with the sleeve pipe inner hole thread and the spline housing outer circumference to the swivel nut of the axial sliding fit of locating.Hollow screw is regulated in the step of the restricted spline housing axial location of the endoporus of swivel nut and the back-moving spring of spline housing and spring restriction, in order to guarantee range adjustment precision of the present utility model, a set nut can be set at the front end that sleeve pipe cooperates with the piston cylinder sheath.
The beneficial effects of the utility model are, the utlity model has need not regulate just can be accurate, quick with easy the advantage of taking or adding multiple different range ultramicron liquid.
