Abstract
The utility model discloses a multifunctional liquid tester, which relates to an instrument for assaying, particularly a multifunctional liquid tester. The multifunctional liquid tester is composed of pistons, a linking board, a unidirectional valve, a shell body, etc. The movement of a plurality of stroke adjustable pistons simultaneously sucks a plurality of sorts of diluents and samples which are discharged to a test tube or other containers after mixed. The utility model has the advantages of simple structure, small volume, light weight, convenient operation, high work efficiency, and good accuracy and repeatability, etc. The multifunctional liquid tester not only can utilize a multiple-piston moving diluter to respectively load irrigators, but also can use the movement of a single piston as a pipette to continuously feed liquid, and can also be matched with other analytical instruments.
Description
The utility model relates to a kind of chemical examination apparatus, refers in particular to a kind of multi-functional liquid measuring instrument device.
Chemical examination is measured and chemico-analytic classic method is to adopt glass pipette to draw respectively in sample and the reagent adding testing tube, again to mix, its shortcoming is that the accuracy that adds the suction amount is influenced by operator's subjective factor, complicated operation is wasted time and energy, inefficiency, when large quantities of samples are measured, bring many inconvenience especially to the operator.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, can quantitatively inhale, arrange plurality of reagents and sample simultaneously and provide a kind of, or add sample separately, adds the multi-functional liquid measuring vessel tool of reagent.
The utility model is achieved by the following scheme: by the piston motion of several adjustable strokes, draw some kinds of dilutions and sample simultaneously, be discharged in testing tube or other containers after mixing.
The utlity model has simple in structurely, volume is little, and is in light weight, easy to use, high efficiency, accuracy, advantages such as good reproducibility, both can utilize many piston motions diluter packing irrigator, also can single piston motion make the continuous charger usefulness of transfer pipet, also can with the supporting use of other analytical instrument.
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing 1 is the utility model embodiment 1 structural drawing;
Accompanying drawing 2 is the utility model embodiment 1 side view;
Accompanying drawing 3 is the utility model embodiment 2 structural drawing;
Accompanying drawing 4 is the utility model embodiment 2 side views;
Accompanying drawing 5 is the utility model embodiment 3 structural drawing.
See accompanying drawing 1,2, the utility model is by motor (1), adjusting knob (2), counter (3), drive screw (4), adjusting screw(rod) (6), setting nut guide rod (7), setting nut (8), interlock plate (9), sample piston (10), reagent piston (11), piston seat (12), feed tube (13), retaining valve (14), discharging tube (15), upper and lower stroke switch (17), (18), shell (19), move back mouth depression bar (21), spring (22) moves back mouth ring (25) sample suction nozzle (24) and forms.Reagent piston (11) places the bottom that two cylinder bodies on the piston seat (12) of retaining valve (14) in the same way are housed respectively, piston (10), (11) a end is fixedlyed connected with adjusting screw(rod) (6), the drive screw (4) that motor (1) drives passes the nut on the interlock plate (9), its two ends are fixed on housing (19) and the bearing (12), setting nut (8) screw thread through guide pole (7) guiding is set on the adjusting screw(rod) (6), adjusting screw(rod) (6) is set in the inner core of counter (3), one guide finger is arranged on its inner tube wall, match with the gathering sill on adjusting screw(rod) (6) top, mouth depression bar (21) lower end of moving back that is loaded on the shell (19) is fixed with one and moves back mouth ring (23), sample suction nozzle (24) is placed in the endpiece of discharging tube (15), spring (22) is set on and moves back on the mouth depression bar (21), on, lower stroke switch (17), (18) be loaded on beginning of interlock plate (9) stroke in the housing (19), final position is put, the advancing of sample piston (10) cylinder body, leakage fluid dram links to each other with the discharging tube (15) of the retaining valve (14) that is connected in reagent piston (11) cylinder body.
When using the utility model, adjusting knob (2) on elder generation's turn housing (19), because of being connected, itself and counter (3) make its rotation, and the stopping of guide pole (7), setting nut (8) only can axially moving along guide pole (7) at adjusting screw(rod) (6), its distance that moves is relevant with the number of turns of adjusting screw(rod) (6) rotation, thereby interlock plate (9) is risen or decline by setting nut (8), after reaching the requirement of adjusting, feed tube (13) is inserted in the reagent, sample suction nozzle (24) inserts in the sample, energized, motor (1) just changes, and drive screw (4) rotates, and interlock plate (9) is threaded with it.Because of guide pole (7) stops, can only axially move at drive screw (4) along guide pole (7), drive sample piston (10), the reagent piston moves on (11), makes both interior negative pressure that forms of cylinder body, two (14) one on retaining valves are open-minded, one is ended, thereby makes feed tube (13) suck reagent, and discharging tube (15) sucks sample, when interlock plate (9) ran to upper stroke switch (17) position, motor (1) quit work; When making motor (1) counter-rotating by the commutation device, interlock plate (9) is descending, the retaining valve (14) that makes feed tube (3) locate ends, the retaining valve (14) that is communicated with discharging tube (15) is open-minded, sample and reagent are discharged through sample suction nozzle (24) by discharging tube (15), and when interlock plate (9) ran to lower stroke switch (18), motor (1) quit work, so repeatedly, can realize that reagent mixes and discharging with the quantitative of sample.
See accompanying drawing 3,4, with tooth bar (25), gear (26) replacement drive screw, exterior power rotates gear (26), and it is upper and lower mobile to drive tooth bar (13), can make interlock plate (9) upper and lower mobile equally, thereby can realize the purpose of this utility model equally.
See accompanying drawing 3, replace drive screw with guide rod (27) and spring (28), exterior power moves guide rod (27), can make interlock plate (9) upper and lower mobile equally, thereby but same this realized the purpose of this utility model.
