Description

The mechanical arm gene-amplificative instrament

The utility model relates to a kind of gene-amplificative instrament that is used for high-tech areas such as biology, medical science, particularly relates to a kind of mechanical arm gene-amplificative instrament of roller type circumference operation scheme.

Existing mechanical arm gene-amplificative instrament is a kind of three water or oil bath pans that are the differing temps of circumference trisection distribution of placing respectively on instrument, the mechanical arm straight line moves up and down and enters, leaving water or oil bath pan, moves in a circle then to arrive next water or oil bath pan.This class amplification instrument complicated in mechanical structure is made up of many covers driving part, and motor is restive, breaks down and causes the failure of an experiment.Other has a kind of mechanical arm gene-amplificative instrament slightly to improve than preceding kind; its operation is mechanical arm one end location; the other end is presented the structure of lower edge arching trajectory operation; but because mechanical part is too simple, the intersection does not have any lubrication fittings in electric machine main shaft and the track ring center of circle; cause the electric machine main shaft sleeve to be subjected to the stressed inclination of mechanical arm one side, cause operation to be obstructed.Mechanical arm slides along arching trajectory in addition; specimen holder sample more than one; mechanical arm slides the resistance that bears and frictional force and to the cushion effect that ebb slides, making repeatedly circulation bear the not too big synchronous stepper-motor of weight originally and being difficult to finish smoothly whole experiment or occurring incomplete phenomena midway to the track peak.In a word, result of use is not fully up to expectations.

The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, reliable, the accurate mechanical arm gene-amplificative instrament in location.

The technical solution of the utility model is: a kind of mechanical arm gene-amplificative instrament, mainly be by three water or oil bath pan, solid-state heating electric rangette, cooling fan, motor, laboratory bench, box body, control panel, mechanical arm, composition such as specimen holder and computer control, its characteristics are: TV is provided with the mechanical arm controlling organization, the mechanical arm controlling organization is by cone gear, rack sleeve, transmission rod, cone pinion, sealing cover and bearing are formed, wherein cone gear and laboratory bench are twisted on motor by countersunk head sieve bolt, the be placed in third-class office of cone gear of three water or oil bath pan, electric machine main shaft and rack sleeve one end are pegged graft, the rack sleeve the other end is connected with transmission rod one end, the transmission rod the other end crosses bearing bore diameter, bearing outside diameter and cone pinion close adhesion, specimen holder is connected with mechanical arm one end, and the mechanical arm the other end crosses bearing.

Owing to adopt such scheme, to be not difficult to draw as drawing a conclusion, the utility model is skillfully constructed, and is simple in structure and do not lose reliable and location accurately.Easy to manufacture, failure rate is low, has improved experiment success rate widely, has industrial utilization.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a front of the present utility model cut-away structure chart;

Fig. 2 is the diagrammatic cross-section of mechanical arm controlling organization of the present utility model;

Fig. 3 is the structural representation of dust guard of the present utility model.

Among the figure, motor 400 is provided with mechanical arm controlling organization 700, cone gear 701 and laboratory bench 500 in the mechanical arm controlling organization 700, pass by countersunk head sieve bolt and to twist on motor 400, so just in time fixed cone gear 701, again motor 400 counter being embedded in the laboratory bench 500, the be placed in third-class office of cone gear 701 of three water or oil bath pan 100, electric machine main shaft 705 is pegged graft fixing with sieve bolt 716 with rack sleeve 704 1 ends.Rack sleeve 704 crosses the crossing with it place of cone gear 701 and adds a bearing 703, make bearing 703 internal diameters and rack sleeve 704 closely sticking platforms, bearing 703 external diameters and cone gear 701 center of circle endoporus kissings merge with sieve bolt 715 fixing, rack sleeve 704 the other ends are 90 ° of right angles with transmission rod 706 1 ends with sieve bolt 702 and are connected, transmission rod 706 the other ends cross bearing 708 internal diameters and fixing with sieve cap 711, and bearing 708 external diameters just in time closely glue platform with cone pinion 709 center of circle endoporus.Porous specimen holder 714 is connected with mechanical arm 713 1 ends, mechanical arm 713 the other ends cross bearing 712 internal diameters and fixing with sieve cap 707, the circular seal of bearing 712 external diameters and diameter and cone pinion 709 equal diameters is covered the eccentric circular hole tight connecting at 710 edges, cone pinion 709 one side that sieve cap arranged and circular seal lid 710 have the one side close adhesion of sieve cap then, and fix with countersunk head sieve silk.704 runnings of the motor partly controlled of computer control 400 energising rack sleeves make transmission rod 706 transmission cone pinions 709 be circumferential running along circumference master wheel 701 like this, make to look tool arm 713 and also be circumferential running up and down with cone pinion 709.And three solid-state heating electric rangettes 200 place three water or oil bath pan 100 thes bottom of a pan, and cooling fan 300 is fixed on motor 400, two centimetres of left and right sides noodle preparation machine casing 600 base plates.Box body 600 is provided with control panel 601, panel is provided with operating key and function button and display screen, can key in experimental procedure by actual needs during experiment, control partly by computer control then that mechanical arm controlling organization 700 drives mechanical arms 713 and specimen holder 714 is finished whole experiment.Wherein laboratory bench 500 is provided with dust guard 800, the position corresponding on the dust guard 800 with water or oil bath pan 100, offer circle-shaped little breather hole 801, with the corresponding position of specimen holder 714 zero positions, offer application of sample window 802, application of sample window 802 offers chute, and plate inserts in it and opens or closes.

The gene amplification experiment condition generally is to place different time at the water of three differing tempss or oil bath pan, finishes by certain cycle index.Because of large and small gear 701,709 sizes of circular cone are 1 to 3, if its cone pinion 709 eccentric mechanical arms 713 are from instrument experiment worktable 500 climaxs, ebb starting point is the place that divides equally of two water or oil bath pan 100 distances, then cone pinion 709 runnings are 180 °, specimen holder 714 on the mechanical arm 713 enters water or oil bath pan 100, rerun 180 ° and come up to the place that divides equally of first and second two pots of distances, cone pinion 709 turns round altogether up and down and three weeks got back to starting point like this.The cone pinion 709 that circles of fortune on cone gear 701, mechanical arm is three water of approach or oil bath pan 100 about in the of 713, and promptly the porous specimen holder 714 on the mechanical arm 713 is taken sample passed by three peaks and three ebbs, promptly reaches experiment purpose so repeatedly.
