Description
Technical field
The utility model relates to the pipettor that is used for chemical experiment or biochemical analysis.
Background technology
The basic functional principle of pipettor is the reciprocating motion through piston, its chamber inner air pressure is reduced or increases, and under the atmospheric effect in the external world, realize imbibition and discharge opeing.And a requisite desorption head operation is all arranged in experimentation: it generally is to use the depress button, presses and unloads suction nozzle by moving back the headgear bar again.At present, world-renowned brand has the Eppendorf of Germany, the Gilson, the Rainin of the U.S. etc. of France, these brands to move back headgear bar start-stop position all constant, end face distance is constant between itself and suction nozzle bar.In addition, the Socorex brand of Switzerland is arranged, through helicitic texture rotation loop bar, scalable loop bar start-stop position makes between itself and suction nozzle bar end face distance adjust.Along with the continuous development of industry technology, relevant speciality manufacturer continues to bring out, the suction nozzle of maximum consumption article in using as pipettor, its specification has increased many, load onto pipettor with different suction nozzles after, suction nozzle and the variation of loop bar end distance are greatly.Spacing is excessive, and loop bar can't push away suction nozzle and just can't it be moved back and unload; Perhaps just do not have spacing, suction nozzle is not just adorned pipettor from beginning at all.Like this, spacing is adjustable just seems particularly important.Though the loop bar of Switzerland Socorex brand pipettor and the spacing of soup stick end surface are adjustable, it is directly to rotate loop bar to regulate, and this mode not too meets most of people's operating habits, and the loop bar off normal is relatively large during use.
Summary of the invention
The purpose of the utility model is to provide a kind of suction nozzle bar adjustable pipette of easy, laborsaving, good stability.
The utility model is that the technical scheme that is adopted that achieves the above object is: a kind of suction nozzle bar adjustable pipette comprises the suction nozzle bar that has liquid sucting port, the handle through being threaded in suction nozzle masthead end, is sleeved on loop bar on the suction nozzle bar, is arranged on piston in the suction nozzle bar, can impels loop bar along the axially movable sliding sleeve of suction nozzle bar and the spring that can impel loop bar under no external force effect, to reset;
The regulating sleeve that also comprises the spacing of a scalable loop bar and soup stick end surface; The top of regulating sleeve is connected with sliding sleeve, and the relative sliding sleeve of regulating sleeve can only rotate; The regulating sleeve bottom is provided with internal thread, and loop bar top is provided with external screw thread, between regulating sleeve and the loop bar for being threaded.
Alternatively, be provided with between loop bar and the suction nozzle bar and only allow the axially movable guiding sunk key of loop bar to cooperate, loop bar is provided with gathering sill, and the suction nozzle bar is provided with the feather key that cooperates with gathering sill.
Alternatively, regulating sleeve is connected for being nested with sliding sleeve, and the position that is nested of regulating sleeve and sliding sleeve is provided with convex annular, and sliding sleeve is provided with and supplies the cannelure that the convex annular embedding cooperates on the regulating sleeve.
The utility model design science, simple in structure, the direct object that reasonably will regulate operation separates with destination object, has effectively expanded the adaptive scope of suction nozzle rod end and suction nozzle, greatly facilitates use.
Description of drawings
Fig. 1 is the generalized section of the utility model preferred embodiment.
The specific embodiment
To combine accompanying drawing and embodiment that the utility model is described further below:
As shown in Figure 1; A kind of suction nozzle bar adjustable pipette comprises the suction nozzle bar 1 that has liquid sucting port 11, the handle 2 through being threaded in suction nozzle masthead end, is sleeved on loop bar 4 on the suction nozzle bar, is arranged on piston 3 in the suction nozzle bar, can impels loop bar along the axially movable sliding sleeve 5 of suction nozzle bar and the spring 6 that can impel loop bar under no external force effect, to reset;
The regulating sleeve 7 that also comprises the spacing A of a scalable loop bar 4 and soup stick head 1 end face; The top of regulating sleeve 7 is connected with sliding sleeve 5, and the relative sliding sleeve 5 of regulating sleeve can only rotate; The regulating sleeve bottom is provided with internal thread 72, and loop bar top is provided with external screw thread 42, between regulating sleeve 7 and the loop bar 4 for being threaded.
Be provided with between loop bar and the suction nozzle bar and only allow the axially movable guiding sunk key of loop bar to cooperate, loop bar is provided with gathering sill 41, and the suction nozzle bar is provided with the feather key 12 that cooperates with gathering sill.The guiding sunk key cooperates, and said suction nozzle bar is provided with gathering sill, and loop bar is provided with the feather key that cooperates with gathering sill.
The connected mode that relative sliding sleeve 5 can only rotate between regulating sleeve 7 sliding sleeves 5 has multiple implementation.Said regulating sleeve 7 is connected for being nested with sliding sleeve 5, and regulating sleeve 7 is provided with convex annular 71 with the position that is nested of sliding sleeve, and sliding sleeve 5 is provided with and supplies the cannelure 51 that convex annular 71 embeddings cooperate on the regulating sleeve.Being nested to connect also can be, said sliding sleeve 5 is provided with convex annular with the position that is nested of regulating sleeve, and regulating sleeve is provided with and supplies the cannelure that the convex annular embedding cooperates on the sliding sleeve.Above-mentioned cooperation makes the regulating sleeve 7 that is sleeved on 5 of loop bar 4 and sliding sleeves can only rotate and can not move axially.
The end that regulating sleeve is threaded with loop bar is provided with the seam groove 73 that the restriction loop bar continues precession.Can effectively prevent to be threaded terminal screw naturally locked, when making regulating sleeve 7 reverse rotations more lightly, more laborsaving, the while has also reduced the influence to other assembled tightness.
The method for using of the utility model is: rotary regulating sleeve 7 can drive loop bar 4 and move axially along suction nozzle bar 1.Realize the adjusting of loop bar 4 and suction nozzle bar 1 end face distance A, this mode of adjusting distance A through turn regulating sleeve 7 meets people's operating habit very much.The operator can insert the suction nozzle bar 1 end tapering degree of depth according to different suction nozzles and require to differ, and A suitably adjusts to end face distance.After distance A is adjusted, can suction nozzle be installed in suction nozzle bar 1 tapering end smoothly, after completion moves the liquid operation.The operator only needs to apply descending thrust to being sleeved on handle 2 outer sliding sleeves 5, can loop bar 4 moved down through regulating sleeve 7, will be plugged on the suction nozzle removal of suction nozzle bar 1 tapering end by loop bar 4.Loop bar 4 and suction nozzle bar 1 end face distance A scalable function have effectively been expanded the adaptive scope of suction nozzle bar 1 end and suction nozzle, greatly facilitate use.
