Description
【Technical field】
The utility model belongs to medical testing equipment field, and in particular to a kind of automatic Thinprep pap test pelleter, which is used, to be added
Sample needle construction.
【Background technology】
Sample needle on existing Thinprep pap test pelleter, is vertical single design, the drive mechanism of pelleter is upper
In lower running, it is inaccurate to occur positioning because wearing and tearing precise decreasing, and sample needle is during sampling and sample-adding, under it
Impulse force can produce bounce and cause hard damage to the track of drive mechanism structure, influence the service life of pelleter, it is necessary to enter one
Step is improved.
【The content of the invention】
The purpose of this utility model is to overcome the deficiencies in the prior art to be used there is provided a kind of automatic Thinprep pap test pelleter
Needle construction is loaded, the smart structural design is simple in construction, effectively prevent the hard damage of sample needle and track, improves sample-adding
The running precision of pin.
The utility model is achieved through the following technical solutions：
A kind of automatic Thinprep pap test pelleter sample-adding needle construction, including the slide rail on machine frame movement arm, institute
The slide rail stated is provided with the sample needle that can be moved up and down along it and drives the motor for being loaded needle movement, it is characterised in that institute
The sample needle stated includes upper and lower part, and described top is connected with described bottom by yielding coupling.
A kind of automatic Thinprep pap test pelleter sample-adding needle construction as described above, it is characterised in that described slide rail
Provided with the sliding seat that can be slid along, the top of the sample needle is connected on described sliding seat.
A kind of automatic Thinprep pap test pelleter sample-adding needle construction as described above, it is characterised in that described top
It is connected to by fixed seat on described sliding seat.
A kind of automatic Thinprep pap test pelleter sample-adding needle construction as described above, it is characterised in that described slide rail
Immovable positioning seat is provided with, the bottom of the sample needle is located in the positioning seat.
A kind of automatic Thinprep pap test pelleter sample-adding needle construction as described above, it is characterised in that described positioning
Seat is arranged on by fixed block on described slide rail.
A kind of automatic Thinprep pap test pelleter sample-adding needle construction as described above, it is characterised in that described positioning
Seat is provided with the slide guide flange being set on sample needle.
A kind of automatic Thinprep pap test pelleter sample-adding needle construction as described above, it is characterised in that described positioning
Seat is L-shaped fixed plate.
A kind of automatic Thinprep pap test pelleter sample-adding needle construction as described above, it is characterised in that the positioning seat
On through-hole diameter be less than the sample needle to insert the centrifugation pipe diameter taken, more than the diameter of the sample needle.
Compared with prior art, the utility model has the following advantages that：
Sample needle in the utility model is divided into upper and lower part, and two parts are connected by yielding coupling, and sample needle is inserted
Lower punch power is excessive when taking centrifuge tube, and the bounce formed to sample needle, by buffering, sends the anti-of top to by yielding coupling
Impulse force is greatly reduced, it is to avoid the undershoot of sample needle inserts to take causes hard damage to slide rail during centrifuge tube；Positioning seat is set on slide rail,
On positioning seat set slide guide flange, sample needle bottom is interspersed in positioning seat and slide guide flange and slide up and down, with fixed seat from
Two ends position the axial movement of sample needle, more accurate positioning so that pelleter control is easier, meanwhile, positioning seat, which is also functioned to, to move back
Pipe is acted on, and simplifies sample-adding needle construction, reduces loss.
【Brief description of the drawings】
Fig. 1 is the utility model application state dimensional structure diagram；
Fig. 2 is the structural representation that the utility model is arranged on slide rail；
Fig. 3 is the utility model dimensional structure diagram.
【Embodiment】
The utility model is described in further detail with reference to Figure of description：
As Figure 1-3, a kind of automatic Thinprep pap test pelleter sample-adding needle construction, including located at machine frame movement arm
Slide rail 2 on 1, slide rail 2 is vertically arranged, and slide rail 2 be slided provided with the sample needle 3 and driving sample needle 3 that can be moved up and down along it
Dynamic motor 20, the sample needle 3 includes top 31 and bottom 32, and top 31 is connected with bottom 32 by yielding coupling 33.When
Sample needle 3, which glides, to be inserted when taking centrifuge tube, prevents bounce from causing damage to slide rail.
Preferably, provided with the sliding seat 4 that can be slided along the slide rail 2 on slide rail 2, the top 31 of sample needle 3 is connected to cunning
On dynamic seat 4.Further, top 31 is connected on sliding seat 4 by fixed seat 5.Further, the upper end of sample needle 3,
I.e.：The upper end on top 31 is fixed on sliding seat 4.
Preferably, slide rail 2 is provided with immovable positioning seat 6, and positioning seat 6 is arranged on slide rail 2 by fixed block 7,
The bottom 32 of sample needle 3 is located in positioning seat 6, further, and positioning seat 6 is provided with the slide guide flange 8 for being set in sample needle 3
On, the bottom 32 of sample needle 3 passes through slide guide flange 8 and positioning seat 6, i.e. the bottom of sample needle 3 is located in slide guide flange 8 and positioning
In seat 6 and being capable of up and down motion in it.Positioning seat 6 coordinates the axial movement for being oriented to sample needle 3 with fixed seat 5, makes positioning more
Precisely.Slide guide flange 8 can also reduce frictionally damage when sample needle 3 is slided.
Further, the through-hole diameter on positioning seat 6, which is less than sample needle 3, will insert the centrifugation pipe diameter taken, more than sample needle 3
Diameter, more saying is, the diameter passed through on L-shaped positioning seat 6 and slide guide flange 8 for sample needle 3 is less than centrifugation pipe diameter, slightly
More than the diameter of sample needle 3, the axial movement of sample needle 3 can be oriented to, while being easy to centrifuge tube of decorporating after sample-adding.
