The bottom of many incubators is shown with simple illustration in Fig. 1, and its insulation cabinet 11 has a same refrigerating chamber 13 by thermal insulating door thermally insulated door 12 closures.Refrigerating chamber is by plastic inner lining 14 linings of the non-cutting shaping of a covering cabinet 11 heat-insulation layers.This liner its be basically perpendicular to have on the sidewalls 15 (a fan sidewall only is shown among the figure) that door 12 stretches parallel up and down, be provided with at interval, the cross section is guidance type spare shape, that be used to form roller draw-off mechanism 16, the guidance type spare 17 that the upper strata is provided with is equipped with that a continuous horizontal stretches, as can to touch door 12 roll extrusion rail 18.The roll extrusion rail 18 of the guidance type spare 17 that is provided with on two side 15 is as the rolling surface that belongs to the roller 20 (only can see among the figure) of all thing drawers 19 of drawer-like, roller can be rotatably set in storing drawer 19 with the opposing adjacent scope of end face of door 12 in the framework 21 around its opening on.The reveal end scope diagonal angle of the storing drawer 19 on the opposite of the roller 20 on the roll extrusion rail 18 that is bearing in two side 15 guidance type spares 17 is provided with the roller 22 that constitutes pair of rollers, and this roller can be rotatably set in the bottom of storing drawer 19.Storing drawer 19 has its free end and deviates from the convex shoulder 23 that bottom direction is pointed in the adjacent scope of door distal face.Convex shoulder 23 and storing drawer 19 sidewalls in one plane and are equipped with fastener 24 pin configuration, that its axis is basic and storing drawer 19 sidewalls vertically are provided with at its free end.This fastener is enclosed within on the convex shoulder 23 by free ring, and rotates mutually with the convex shoulder free end.Below shaped as pin fastener 24, on the two side 15 of insulation cabinet 11, be provided with the roll extrusion rail 26 that belongs to guidance type spare 25 that the cross section is a shape, the roll extrusion rail forms bending in its door proximal segment corresponding to horizontally disposed door distal ports.Above bending, on two each guidance type spares 25 that are arranged on the sidewall 15, directly with the adjacent of door 12, every side rotatably is provided with a roller 27, and the height of the peak of roller is identical with roll extrusion rail 26.This roll extrusion rail is as in the scope of the door distal face that is arranged on storing drawer 28 and the rolling surface of the roller 29 in the adjacent scope of edge of opening, and this roller can be rotatably set in around the framework 30 of edge of opening and side sections sidewall 15 extends parallel.The side section of framework 30 is hollow supporting slat structure 31, and this supporting slat is used to improve the rigidity of himself in the storing drawer 28 that adopts the preparation of compression moulding method, is to adopt the blow moiding method preparation.Supporting slat 31 has the rolling surface that is bearing on the roller 27 at its downside towards roll extrusion rail 26.Because roller 27 is bearing on the rolling surface, be bearing in again on the roll extrusion rail 26 of guidance type spare 25 simultaneously, thereby the roller draw-off mechanism of mentioning when having realized the beginning in this manual of lower floor's storing drawer 28 in the refrigerating chamber 16, so lower floor's storing drawer when door 12 is opened owing to fixedly connected with door and in refrigerating chamber, to be pulled out and can push in the refrigerating chamber.Door 12 mainly is not constitute by being shown specifically the framework that belongs to framework 30 in the drawings with fixedlying connected of storing drawer 28, and framework interconnects at the reveal end and the supporting slat of supporting slat 31.And supporting slat 31 has a rolling surface at its upside towards storing drawer 19, and the roller 22 that is provided with in door proximal end face scope is bearing on the rolling surface and constitutes second the roller draw-off mechanism 16 that is arranged on the storing drawer 19 above the storing drawer 28 jointly with roller 20 on the roll extrusion rail 18 that is bearing in guidance type spare 17.

Except the rolling surface 28 of supporting slat 31 upsides, in the door distal ports scope of supporting slat, also have a hunting gear 32.According to present embodiment, this hunting gear is the reed of arc elastically deformable, and the one end is fixed on the supporting slat 31.Adopt under the situation of compression moulding method preparation at above-mentioned storing drawer 28, can take to realize the method that arc reed embeds on the supporting slat 31 fixing.Arc reed is parallel as the upside of rolling surface with supporting slat 31 basically, and wherein its free end has the deploying portion 33 that has formation importing incline structure, points to storing drawer 19.On the direction of pointing to door 12, fixing lug boss 34 is positioned at the front of this deploying portion, and this fixing lug boss keeps following curved being achieved of certain intervals to the upside of supporting slat 31 by reed.Fixing lug boss 34 on two supporting slats 31 matches with the shaped as pin fastener 24 of discharged kayser on being arranged on storing drawer 19 bottom convex shoulders 23.At it during with 32 one-tenth kayser states of hunting gear that arc reed constitutes, because the upper strata storing drawer 19 in the refrigerating chamber 13 is than lower floor's storing drawer 28 about short 30%, storing drawer 19 also moves thereupon when storing drawer 28 moves, thereby when being pulled out in refrigerating chamber 13 when lower floor's storing drawer 28 is opened with being fixedly connected on of door 12 by it, two

storing drawers

19 and 28 are pulled out in refrigerating chamber 13 together.Because two storing drawers 19 are different with 28 length, thereby can check two storing drawers simultaneously when pulling out state, wherein can improve checking storing drawer 28 greatly by storing drawer 19 transparent bottoms.In addition by shortening upper strata storing drawer 19, thereby can in storing drawer 28 reveal panel scopes, put and be contained in the high container for example bottled thing that stores.If want to touch the door distal ports of storing drawer 28, only need contrary pull-out direction that storing drawer 19 is applied the kayser that effect can discharge upper strata storing drawer 19.

When two

storing drawers

19 and 28 arrive its final position by not shown retainer sign, when this fixed-site boss 34 just in time blocks shaped as pin fastener 24, by realizing the kayser of two

storing drawers

19 and 28 to storing drawer 28 automatically again to pushing back.

Fig. 3 and Fig. 4 show another servo-actuated scheme of upper strata storing drawer 19.Storing drawer 28 is equipped with supporting slat 40 this moment, and the difference of itself and supporting slat 31 is, at the holddown groove that has a formation hunting gear 41 towards the upside of storing drawer 19 respectively.This holddown groove is the projection of even arc, and its radius of curvature is coincide with the radius that is arranged on the roller 22 in 19 proximal face scopes of storing drawer and thereby constituted the fixing of pair roller.On the direction that pushes refrigerating chamber 13 of storing drawer 28, fixedly convex shoulder 42 directly is adjacent to the front as the hunting gear 41 of holddown groove, this fixedly the convex shoulder pull-out direction that plays

contrary storing drawer

19 and 28 strengthen kayser effect as the hunting gear 41 of holddown groove.

Owing to strengthen 3 kayser effects, even thereby guaranteed that storing drawer 19 under bigger contrary inertia force effect by refrigerating chamber 13 pull-out directions, also can be fixed in the holddown groove as kayser.Identical with the explanation in Fig. 1 and Fig. 2, storing drawer 19 is pulled out in refrigerating chamber 13 with the storing drawer 28 of pulling out in by refrigerating chamber 13 when door 12 is opened.If, then only need the door proximal segment of storing drawer 19 is mentioned slightly, so that overcome the kayser of realizing servo-actuated owing to will must push upper strata storing drawer 19 in the refrigerating chamber 13 toward lower floor's storing drawer 28 contents.Closing door 12 and realizing that the storing drawer 28 that is connected with door pushes in the process of refrigerating chamber 13, the storing drawer 19 that is provided with thereon since with the side of the opposing fixedly convex shoulder 42 of holddown groove, also be pushed in the refrigerating chamber 13, until the final position that arrives the retainer sign that is not shown specifically.This moment, roller 22 was pressed into the latched position that realizes servo-actuated again again.

Especially can find out from Fig. 5 and Fig. 6 that the fixation of the hunting gear of realizing by the moulding of holddown groove on storing drawer 28 supporting slats 50 51 can be strengthened by the reed 53 that is arranged on the support strip 52.But the spring body of its elastic deflection acts on the roller that is positioned at holddown groove 22 of upper strata storing drawer 19 under certain prestressing force for this reason, wherein can change fixation by the elastic characteristic curve that reed 53 correspondingly is set.When above-mentioned situation, by reed 53 being embedded in the breach 54 of the longitudinal side that is positioned at the bottom of supporting slat 52, until the position that reaches elastic strength, thus the elastomer of realization reed 53, this breach is determining the length that reed 53 freely stretches out.Support strip 52 be should be taken into account its height above the roller 22 of upper strata container 19, be fixedly installed on the sidewall 15 of liner 14, so that the peak of roller 22 and towards the gap of leaving trace between the longitudinal side, bottom of the support strip 52 of roller.This determining dimensions guaranteed in the scope of reed 53 of roller 22 effect of not only being fixed on it, and also is fixed on the length of whole support strip 52 in the holddown groove as hunting gear 51.In addition, pulled out from refrigerating chamber 13 and storing drawer 19 pushes when being arranged on outside the holddown groove that load-bearing lath 50 has under the situation in the refrigerating chamber 13 at storing drawer 28 when support strip, then the support strip 52 that is provided with on two side 15 utilizes its end face towards door 12 also to have the stop function of roller 22.Because roller 22 is limited on the end face of plate washer 52, so upper strata storing drawer 19 is maintained on the certain position, be pushed into refrigerating chamber 13 and door 12 when being closed in this position when storing drawer 28, roller 22 can be stuck in again in the hunting gear 51 as holddown groove again automatically.In addition, another function of the support strip 52 that is provided with on sidewall 15 is, when clean storing drawer 28 or storing drawer 28 put article or even when unconsciously storing drawer 28 being pulled out in fully by refrigerating chamber 13, play a part to support storing drawer 19.

The foregoing description is changed, also can adopt corresponding hunting gear to realize wherein can taking to realize the hysteresis servo-actuated as the corresponding extending longitudinally of hunting gear 32 arc reeds or the method for corresponding lengthening holddown groove by shortening the leading function of the storing drawer when door 12 is opened that upper strata storing drawer 19 causes 28.
