Description
Technical field
It the utility model is related to a kind of rotary head of miniature centrifuger attachment means.
Background technology
, it is necessary to apply to substantial amounts of liquid separation in current field of medical examination, particularly medical science and molecular biology
Experiment.For example, traditional PCR (PCR) is using front and rear, it is necessary to by the extension drop separation of porous plate totally, be
It is remaining in removing porous plate to hang drop, generally porous plate is centrifuged using centrifuge and removed water.The master of existing centrifuge
Part is wanted to include housing, the direct current generator being arranged in housing and the rotary head being arranged on direct current generator, rotary head is used to carry
The centrifuge tube centrifuged is needed, rotary head is to be locked by screw in the rotating shaft of motor, because the species of centrifuge tube is numerous
It is more, to adapt to various centrifuge tubes and be configured with a variety of centrifugal heads and adapter, it is necessary to when changing rotary head, to look for special dismounting
Instrument, with screw is extracted energetically when unclamping screw, such dismounting mode is cumbersome and time-consuming, it is important that installs number
After repeatedly, the mounting hole of rotary head working of plastics has abrasion, influences the concentricity of rotary head and rotating shaft, causes the generation of bias, turns
Very big vibration is produced during head high speed centrifugation, not only produces noise, and influences the life-span of direct current generator bearing, this there is
Certain weak point.
Utility model content
Technical problem to be solved in the utility model is overcome the deficiencies in the prior art, there is provided one kind dismounting is easy to be fast
Victory, it is avoided that rotary head changes with rotating shaft concentricity and produces noise, improves the rotary head of miniature centrifuger of product service life
Attachment means.
Technical scheme is used by the utility model：The utility model includes direct current generator, machine shaft set, centrifuge tube
Rotary head, the bottom of the machine shaft set are fixedly installed on by screw in the rotating shaft of the direct current generator, the centrifugation
Pipe rotary head buckle is arranged on the machine shaft and put.
The top both sides of the machine shaft set are correspondingly arranged on two elastic card buckles, and the elastic card buckle passes through institute
State the loading end that the centrifuge tube rotary head is buckled in after centrifuge tube rotary head.
The top of machine shaft set and it is provided with stopper section on the inside of the elastic card buckle.
The section of the machine shaft set is rounded, and the bottom of the centrifuge tube rotary head is provided with circular groove, the circle
Connected in star wraps the upper end of the machine shaft set and coordinated with machine shaft set gap.
The beneficial effects of the utility model are：Turn because the utility model includes direct current generator, machine shaft set, centrifuge tube
Head, the bottom of the machine shaft set are fixedly installed on by screw in the rotating shaft of the direct current generator, the centrifuge tube
Rotary head buckle is arranged on the machine shaft and put, and compared with prior art, adds the machine shaft set, the motor turns
Axle sleeve is once fixedly installed on the direct current generator is arranged on institute without dismounting, the centrifuge tube rotary head in the form of buckle
State machine shaft to put, so the utility model dismounting is simple and efficient, is avoided that rotary head and rotating shaft concentricity change and produced
Raw noise, improve product service life.
Brief description of the drawings
Fig. 1 is explosive view of the present utility model；
Fig. 2 is sectional view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model includes direct current generator 1, machine shaft set 2, centrifuge tube rotary head 3, the electricity
The bottom of machine rotating shaft set 2 is fixedly installed on by screw 4 in the rotating shaft of the direct current generator 1, and the centrifuge tube rotary head 3 blocks
Button is arranged on the machine shaft set 2, by such mode, compared with original structure, adds the machine shaft set 2
As a fitting, the machine shaft set 2 can be fixedly installed on the disassembly and installation avoided on the direct current generator 1, so as to not
Can influence the concentricity with the direct current generator 1, and the centrifuge tube rotary head 3 can by way of buckle with the machine shaft
Set 2 is fitted close, ensure the centrifuge tube rotary head 3 can realize it is atwirl on the basis of quickly changed the outfit, specifically
For, the top both sides of the machine shaft set 2 are correspondingly arranged on two elastic card buckles 21, and the elastic card buckle 21 passes through
The loading end 31 of the centrifuge tube rotary head 3 is buckled in after the centrifuge tube rotary head 3, in addition, in order to avoid described in damage during dismounting
Elastic card buckle 21, the machine shaft cover 2 top and the inner side of the elastic card buckle 21 are provided with stopper section 22,
The section of the machine shaft set 2 is rounded, and the bottom of the centrifuge tube rotary head 3 is provided with circular groove 32, and the circle is recessed
Groove 32, which wraps the upper end of the machine shaft set 2 and covers 2 gaps with the machine shaft, to be coordinated.
The utility model is applied to micro centrifuge field.
