Further, described two grades of shifting liquid bars also comprise guide rod and position-arresting disk, being provided with on described position-arresting disk and described square section of adaptive square hole, the lower end of two described guide rods is fixedly connected with the upper side of described wear ring, and described position-arresting disk is provided with two through holes corresponding with described guide rod.
Specifically, two described guide rods are symmetrical arranged along the axis of described position-arresting disk.
Specifically, described wear ring and described one-level move between liquid bar, the outer side of described shifting liquid plug and the outer side of described two grades of seal sections moving liquid bars be provided with anti-slip rubber layer.
Specifically, described transfer pipet, described shifting liquid plug, described one-level shifting liquid bar, described two grades of axis moving liquid bars and described position-arresting disk all overlap.
The beneficial effects of the utility model are:
The utility model dual control adjustable type pipettor moves, by one-level, the shifting liquid operation that liquid bar carries out large volume, moves, by two grades, the shifting liquid operation that liquid bar carries out small volume, by two ore control, reaches the object accurately moving liquid measure, be easy to operation.
Accompanying drawing explanation
Fig. 1 is the sectional view of dual control adjustable type pipettor described in the utility model;
Fig. 2 is the vertical view of dual control adjustable type pipettor described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model comprises transfer pipet 1, move liquid plug 3, one-level moves liquid bar 5, two grades are moved liquid bar 6, guide rod 7 and position-arresting disk 8, the lower end of transfer pipet 1 is provided with the shifting liquid head 2 of circular cone shape, moving liquid plug 3 is arranged in transfer pipet 1, the lower end that one-level moves liquid bar 5 is fixedly connected with the upper side moving liquid plug 3, it is provided with the straight hole along its axis in one-level transfer pipet 1 and shifting liquid plug 3, two grades are moved liquid bar 6 and are arranged in straight hole, the upper end of transfer pipet 1 is fixedly installed the wear ring of the outer side sealing moving liquid bar 5 with one-level, two grades are moved liquid bar 6 and comprise square section 61, thread segment 62 and seal section, the upper semisection of straight hole is provided with and the outside screw of thread segment 62 adaptation, the lower semisection of straight hole is smooth section and contacts with seal section sealing, move liquid plug 3 to contact with the interior side seal of transfer pipet 1, position-arresting disk 8 is provided with and the square hole of square section of 61 adaptations, the lower end of two guide rods 7 is fixedly connected with the upper side of wear ring, position-arresting disk 8 is provided with two through holes corresponding with guide rod 7, two guide rods 7 are symmetrical arranged along the axis of position-arresting disk 8, wear ring and one-level are moved between liquid bar 5, the outer side of the outer side and two grades of seal sections moving liquid bar 6 that move liquid plug 3 is provided with anti-slip rubber layer, transfer pipet 1, move liquid plug 3, one-level moves liquid bar 5, two grades of axis moving liquid bar 6 and position-arresting disk 8 all overlap.
The principle of work of the utility model dual control adjustable type pipettor is as follows:
One-level is moved liquid bar 5 and is pulled upwardly extracting liquid in transfer pipet 1, when carrying out needing the liquid discharged in transfer pipet 1 moving liquid, position-arresting disk 8 is first inserted to two grades to be moved on liquid bar 6 and guide rod 7, the square hole of position-arresting disk 8 is coordinated with two grades square section 61 moved on liquid bar 6, and two through hole covers are filled on guide rod 7, it is connected because position-arresting disk 8 moves liquid bar 6 by square hole with two grades, and the catercorner length of square section 61 equals the diameter of spiro rod section, so position-arresting disk 8 and two grades of shifting liquid bars 6 do not move up and down or rotate, and position-arresting disk 8 is fixed by guide rod 7 and wear ring, make not relatively rotate between position-arresting disk 8 and wear ring, one-level moves liquid bar 5 and two grades of shifting liquid bars 6 are threaded connection, therefore by pushing position-arresting disk 8 downwards, one-level hydraulic stem can be made to move down along transfer pipet 1 together with 2-level hydraulic bar, liquid in transfer pipet 1 is discharged by it, realize the shifting liquid of large volume,
When needing the shifting liquid carrying out small volume, position-arresting disk 8 is taken out from the upper end that two grades are moved liquid bar 6 and guide rod 7, liquid bar 6 is moved by rotating two grades, make two grades to move liquid bar 6 threadingly to move down, so that two grades of seal sections moving liquid bar 6 stretch out, continue to discharge by the liquid in transfer pipet 1, because the diameter moving liquid plug 3 moves the diameter of liquid bar 6 much larger than two grades, therefore can realize the shifting liquid of small volume.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection domain of the present utility model.
