The specific embodiment:
The embodiment that Fig. 1 shows is the overall appearance of the utility model.
The embodiment that Fig. 2 shows is the internal structure of the utility model.Napex is the accent amount knob button 1 of holding concurrently; Hold concurrently button 1 of accent amount knob is connected with several wheel assemblies and digital display window 8 with batcher 7 through transferring gauge rod 2; Transfer gauge rod cylindrical cavity end 9 to be connected with air row soup stick 13 through crooked push rod 10; Air row soup stick 13 passes from back-moving spring 20, and air row soup stick 13 ends are connected with cavity 21, and new and effective pipettor one side is a handle 15; With handle 15 relative opposite sides be suction nozzle push away row button 4; Suction nozzle pushes away row's button 4 and pushes away tier pole 5 and suction nozzle through suction nozzle and push away row's device 23 and be connected, and suction nozzle pushes away row's push-button reset spring 6 and is fixed on that suction nozzle pushes away row's button spring locator 22 and suction nozzle pushes away between row's button 4, and suction nozzle pushes away tier pole 5 and pushes away row's push-button reset spring 6 middle passing from suction nozzle.Every cover by accent amount knob hold concurrently button 1, pressure buffer spring 16, transfer that gauge rod 2, connector 3, batcher 7, batcher slide slot 17, number wheel assembly and digital display window 8, crooked push rod 10 and crooked push rod guide slot 19 form quantitatively to reach the application of sample parts be separate.Air row soup stick 13, back-moving spring 20, center decide bar 11, suction nozzle and are pushed away row's button 4, suction nozzle and push away tier pole 5, suction nozzle and push away row's push-button reset spring 6, handle 15, suction nozzle and push away row's button spring locator 22, suction nozzle to push away the cavity 21 that row's device 23 and air arrange below the soup stick be shared.
Just combine below concrete operations specify the utility model each functions of components and between relation.When need add simultaneously with a sample two ranges (this sentences two ranges and explains orally, have in the real work pipettor that several different ranges just select several passages just can) when being respectively a and b.
Earlier the x accent amount knob button 1 of holding concurrently is transferred to a range, can sees the range that the pipettor respective channel is current, equally the y accent amount knob button 1 of holding concurrently is transferred to the b range through number wheel assemblies and digital display window 8.
Transfer the process of range to be: rotation accent amount knob hold concurrently button 1 drive transfer gauge rod 2 with transfer 9 rotations of gauge rod cylindrical cavity end (accent amount knob hold concurrently button 1 with transfer gauge rod 2, transfer gauge rod cylindrical cavity end 9 be one with interlock).On the one hand, (under the effect of batcher slide slot 17, batcher 7 can only vertically slide from batcher 7 to transfer gauge rod 2; Can not horizontally rotate, when not pushing accent amount knob and holding concurrently button 1, batcher 7 is being in batcher slide slot 17 tops and fixed under the acting in conjunction of back-moving spring 20, air row's soup stick 13 and crooked push rod 10) in the middle of pass; Lean on screw thread to be connected with batcher 7; Batcher 7 is fixing during the accent amount, transfers gauge rod 2 just can move up and down, and reaches quantitative purpose; On the other hand, transfer gauge rod cylindrical cavity end 9 to drive the number wheel assemblies and digital display window 8 rotates, to show the pipettor accent amount knob current range of button 1 respective channel of holding concurrently.
After mixing up range; Load onto suction nozzle 14; And suction nozzle 14 put in the serum; With thumb press x accent amount knob hold concurrently button 1 drive transfer gauge rod 2, batcher 7, transfer gauge rod cylindrical cavity end 9, crooked push rod 10 and air row soup stick 13 move down together; Back-moving spring 20 shrinks, air row soup stick 13 extruding cavitys 21 and get rid of a range air (accent amount knob hold concurrently button 1, transfer gauge rod 2, batcher 7, transfer gauge rod cylindrical cavity end 9, crooked push rod 10 air row soup stick, 13 and cavity 21 be to be connected each other from top to bottom).Unclamp thumb, back-moving spring 20 diastoles are transferred gauge rod 2, batcher 7, are transferred gauge rod cylindrical cavity end 9, crooked push rod 10 and air row soup stick 13 move on together and reset, and be negative pressure this moment in the cavity 21, the serum inflow suction nozzle 14 of a range.Shift out suction nozzle 14 and suction nozzle 14 alignings are needed the container of application of sample, repeat above-mentioned pressing operation, just accomplish the application of sample operation of a range sample.
Under the situation of not changing pipettor and suction nozzle 14, push-unclamp-push again the operation of button 1 of holding concurrently of y accent amount knob equally, just simply and smoothly accomplished the application of sample operation of b range sample, realize with continuous equivalent of a sample and inequality application of sample continuously.
After a sample is accomplished whole application of samples; Push away row's button 4 with the thumb press suction nozzle; Drive suction nozzle and push away that tier pole 5 presses down, suction nozzle pushes away row's push-button reset spring 6 and shrinks, suction nozzle was just discharged suction nozzle 14 when pushing away row's device 23 and pressing down, and unclamped thumb; Suction nozzle pushes away 6 diastoles of row's push-button reset spring, makes suction nozzle push away row's button 4 and suction nozzle and pushes away tier pole 5 reset (suction nozzle push away row's button 4, suction nozzle push away tier pole 5, suction nozzle push away row's push-button reset spring 6, suction nozzle pushes away row's device 23 and suction nozzle 14 is to be connected each other from top to bottom).
In addition, pressure buffer spring 16 is to be used for cushioning the hold concurrently pressure of button 1 of self-regulated amount knob, parts such as protection is simultaneously transferred gauge rod 2, batcher 7, transferred gauge rod cylindrical cavity end 9, crooked push rod 10, air row's soup stick 13 and back-moving spring 20.Guide slot 12 is to be used for guiding crooked push rod 10 to move up and down and prevent that it from departing from moving direction with crooked push rod guide slot 19, makes crooked push rod 10 can accurately promote air row soup stick 13 and moves down.
