Detailed description of the invention
Fig. 1 is a kind of device for quickly being drawn to the reagent in reagent bottle of embodiment of the utility model
Structural schematic diagram；
Fig. 2 is the external structure schematic diagram of shell in Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 schematically shows a kind of the quick for carrying out to the reagent in reagent bottle of embodiment of the utility model
The structure of the device drawn.
As shown in Figure 1, the device for quickly being drawn to the reagent in reagent bottle, including shell 1；It is fixed at
Cavity 2 is drawn in shell 1, the side wall for drawing cavity 2 is equipped with sliding slot 21；It is slidably disposed within the piston 3 drawn in cavity 2,
The intermediate position of piston 3 is equipped with internal thread hole, and the side of piston 3 is equipped with the protrusion 31 agreed with sliding slot 21；One end fixation is set
It sets and is drawing in cavity 2, the other end is fixed at the first spring 32 on piston 3；Threaded rod 4, the first end 41 of threaded rod 4
Cooperation is threadedly coupled with internal thread hole, the second end 42 of threaded rod 4 is rotationally located on shell 1, and second end 42 extends to shell
The outside of body 1 is fixedly installed in second end 42 and turns round cap 43；And one end is communicatively arranged with cavity 2 is drawn, the other end extends
Dip-tube 5 outside to shell 1, and dip-tube 5 is oppositely disposed about piston 3 and threaded rod 4.As shown in Fig. 2, in this implementation
In example, the transmission gear engaged with the counting gear of digital block code table 7 is additionally provided on threaded rod 4；In this way, passing through rotating threaded rod
4, since the protrusion 31 on the side of piston 3 is embedded into the sliding slot 21 on the side wall for drawing cavity 2, therefore piston 3 can't be with
Threaded rod 4 rotate together, threaded rod 4 produces relative rotation with the internal thread hole on piston 3, then threaded rod 4 can drive work
Plug 3 is moved along sliding slot 21 drawing in cavity 2, so that adjusting 4 piston 3 of threaded rod is drawing position in cavity 2, to reach
The function of drawing 2 volume of cavity is precisely adjusted, while amount of movement is passed to digital block code table 7 by transmission gear by threaded rod 4,
Then the real time volume drawn in cavity 2 is shown by pre-set conversion amount.
The course of work, first rotating threaded rod 4 draw the side wall of cavity 2 since the protrusion 31 on the side of piston 3 is embedded into
On sliding slot 21 in, therefore piston 3 can't be rotated together with threaded rod 4, and the internal thread hole on threaded rod 4 and piston 3 generates
Relatively rotate, then threaded rod 4 can drive piston 3 to be moved along sliding slot 21 drawing in cavity 2, i.e., by regulating piston 3 with
That draws distance between 2 bottom of cavity adjusts the volume drawn in cavity 2, will draw 2 internal volume of cavity and adjusts to preset value,
Then it presses and turns round cap 43, push threaded rod 4 to be depressed into the end for drawing cavity 2 with piston 3, will draw in cavity 2 in this way
Air emptying, while the first spring 32 is compressed, and then dip-tube 5 is moved in the reagent bottle equipped with reagent, is then unclamped
Cap 43 is turned round, under the recovery elastic force effect of the first spring 32, piston 3 is restored to initial position, that is, draws the volume of cavity 2
Again preset value is reset to, it is isometric with 2 preset volume of cavity is drawn then as the volume for drawing cavity 2 resets again
Reagent is drawn into dip-tube 5 or draws in cavity 2, to reach the function of precisely adjusting and draw 2 volume of cavity.
As shown in Figure 1, in the present embodiment, being on the position of the same side also on shell 1 with the second end 42 of threaded rod 4
Equipped with handle end 11, handle end 11 is bent extension along away from the direction of second end 42.
In this way, in use, user can catch on the crooked position in handle end 11 by using index finger, so
It is oppressed again with thumb afterwards and turns round cap 43, singlehanded holding whole device is realized, to realize the function of the one-handed performance device.
As shown in Figure 1, in the present embodiment, further includes: the button 6 being slidably arranged on shell 1；It is set in dip-tube
The promotion set 62 on that one end outside shell 1 is extended on 5；And one end is fixedly connected with button 6, the other end and promotion cover
62 drive rods 61 being fixedly connected.
In this way, when in use, first disposable tip can be nested on dip-tube 5, examination is drawn with disposable tip
Agent, it is to be used it is complete after, by push button 6, button 6 pushes set 62 to move downward by the driving of drive rod 61, thus by primary
Property suction nozzle above push away and fall from dip-tube 5, provided convenience for replacement disposable tip.
As shown in Figure 1, further including that one end is located on shell 1, the other end is located at second on button 6 in the present embodiment
Spring 63.
In this way, disposable tip is above pushed away from dip-tube 5 fall when, second spring 63 is compressed, when by disposable tip
Backwardness, release button 6 are above pushed away from dip-tube 5,63 activation button 6 of second spring resets, and provides convenience for use next time.
As shown in Figure 1, in the present embodiment, turning round and being additionally provided with anti-skid chequer 431 on the side of cap 43.
In this way, by the contact of finger and anti-skid chequer 431, can be obtained bigger when turning round cap 43 using finger rotation
Stiction avoids skidding.
The above is only some embodiments of the utility model.For those of ordinary skill in the art, it is not taking off
Under the premise of from the concept of the present invention, various modifications and improvements can be made, these belong to the utility model
Protection scope.
