Description

A kind of palm centrifuge of low noise

Technical field

It the utility model is related to palm centrifuge field, and in particular to a kind of palm centrifuge of low noise.

Background technology

Palm centrifuge (being called mini centrifuge, microcentrifuge) is simple to operate, it is only necessary to puts micro tube well, covers Lid starts, and rotary head can quickly reach maximum speed, and its centrifugal force is evenly and rapidly applied to the pipe cap and pipe of micro tube On wall, especially suitable for processing PCR pipe and microfiltration, quickly get rid of lower reagent from test tube wall or test tube cap, and test tube or The slow speed centrifugation of comb.

For non-frozen formula centrifuge, for the activity of biological sample, it is necessary to possess circulating air cooling, effectively to reduce rotary head Rotation generates high heat with air severe friction and causes sample to heat up at a high speed；Another aspect circulating air cooling have can cause it is larger Noise, and violent vibrations can be also produced during motor high-speed rotation, so that the noise of palm centrifuge.

Utility model content

The problem of existing for prior art, solve the problems, such as that the palm noise of centrifuger of circulation air cooled is big, this reality With a kind of new palm centrifuge for providing low noise.

Concrete technical scheme is as follows：

A kind of palm centrifuge of low noise, include centrifuge body, blimp and the damping base of circulation air cooled, The damping base includes upper guard board, is fixed on the rubber buffer plate of the upper guard board bottom surface, is fixed on the rubber buffer plate The lower backplate of bottom surface, the damping spring for being uniformly fixed on the lower backplate bottom and it is arranged alternately with the damping spring slow Rush block, be fixed on the damping spring and the supporting plate of the buffer stopper bottom surface, the centrifuge body are fixed on the upper shield On plate, the lateral wall of the centrifuge body is covered with blimp, the sound insulation be covered with being followed successively by acoustical cotton layer, sound-absorbing outside Damping layer, sound insulation steel plate layer, the blimp are placed in the damping base, and the sound insulation steel plate stratification of the blimp In in the supporting plate；

Preferably, the bottom even of the supporting plate is fixed with support feet；

Preferably, cellular through hole is uniformly offered on the damping rubber block；

Preferably, the size of the upper guard board, the rubber buffer plate and the lower backplate is suitable；

Preferably, the buffer stopper is damping rubber block.

Beneficial effect：

The rubber buffer plate with cellular through hole in damping base of the present utility model produces when working centrifuge Vibrations one buffer again, and the resiliency that cellular through hole increases rubber buffer is opened up on rubber buffer plate Energy；The setting of damping spring and buffer stopper shakes the double buffering of progress caused by effectively working centrifuge；And buffer stopper Setting effectively prevent damping spring to be compressed to limiting value and be damaged, effectively extend damping spring use the longevity Life；Caused vibrations in centrifuge work are effectively reduced by above-mentioned double buffering, so as to reduce centrifuge because vibrations are produced Raw noise；Effectively wind caused by circulation air cooled centrifuge is made an uproar for the setting of blimp and noise is isolated in caused by shaking In blimp.

Brief description of the drawings

, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1：Cross-sectional view of the present utility model.

Reference is as follows：

1st, centrifuge body, 2, upper guard board, 3, rubber buffer plate, 4, through hole, 5, lower backplate, 6, damping spring, 7, buffering Block, 8, supporting plate, 9, support feet, 10, acoustical cotton layer, 11, sound-absorbing damping layer, 12, sound insulation steel plate layer.

Embodiment

It is real to the utility model below to make the purpose, technical scheme and advantage of the utility model embodiment clearer The technical scheme applied in example is clearly and completely described, it is clear that described embodiment is that the utility model part is implemented Example, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making wound The every other embodiment obtained under the premise of the property made work, belong to the scope of the utility model protection.

Referring to Fig. 1：A kind of palm centrifuge of low noise, including the centrifuge body 1 of circulation air cooled, blimp and Damping base.

The damping base include upper guard board 2, be fixed on the rubber buffer plate 3 of the bottom surface of upper guard board 2, be fixed on it is described The lower backplate 5 of the bottom surface of rubber buffer plate 3, the damping spring 6 for being uniformly fixed on the bottom of lower backplate 5 and with the damping bullet Buffer stopper 7 that spring 6 is arranged alternately, the supporting plate 8 for being fixed on damping spring 6 and the buffer stopper 7 bottom surface.

The centrifuge body 1 is fixed on the upper guard board 2.

The lateral wall of the centrifuge body 1 is covered with blimp, the sound insulation be covered with being followed successively by acoustical cotton layer outside 10th, sound-absorbing damping layer 11, sound insulation steel plate layer 12, the blimp are placed in the damping base, and the blimp is described Sound insulation steel plate layer 12 is placed in the supporting plate 8.

The bottom even of the supporting plate 8 is fixed with support feet 9；

Cellular through hole 4 is uniformly offered on the damping rubber block 7；

The size of the upper guard board 2, the rubber buffer plate 3 and the lower backplate 5 is suitable；

The buffer stopper 7 is damping rubber block 7.

The rubber buffer plate 3 with cellular through hole 4 in damping base of the present utility model produces when working centrifuge Raw vibrations carry out one and buffered again, and the buffering that cellular through hole 4 increases rubber buffer is opened up on rubber buffer plate 3 Performance；The setting of damping spring 6 and buffer stopper 7 shakes the double buffering of progress caused by effectively working centrifuge；It is and slow Rushing the setting of block 7 effectively prevents damping spring 6 to be compressed to limiting value and be damaged, and effectively extends damping spring 6 Service life；By above-mentioned double buffering effectively reduce centrifuge work in caused vibrations, so as to reduce centrifuge by In noise caused by vibrations；Wind caused by circulation air cooled centrifuge is effectively made an uproar and made an uproar caused by shaking by the setting of blimp Sound is isolated in blimp.

Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to foregoing reality Example is applied the utility model is described in detail, it will be understood by those within the art that：It still can be to preceding State the technical scheme described in each embodiment to modify, or equivalent substitution is carried out to which part technical characteristic；And these Modification is replaced, and the essence of appropriate technical solution is departed from the spirit and model of various embodiments of the utility model technical scheme Enclose.
