Description
Technical field
The utility model relates to the rack that a kind of refrigerator is used, and especially a kind ofly is arranged on the refrigerator freezing shelf that refrigerating chamber bottom can be taken out, and can deposit the article that vary in size.
Background technology
The rack of current refrigerator, particularly refrigerating chamber rack, the rack of normally fixed and iris type, and be provided with the different rack of height, height is different to adapt to, the needs of the article that vary in size.There is not the freezing shelf that can take out in the freezer compartment of refrigerator.
In order to adapt to the needs of the different article storages of height, some adjustable shelves occurred, but be used for refrigerating chamber more.
Application number is 200420011174 Chinese patent (Henan Xinfei Electric Appliance Co., Ltd) but discloses a kind of shelf of free adjustment height, belongs to refrigerator appurtenance technical field.Comprise vertical guide pillar and wear extension shelf thereon, be provided with the shelves high guiding mechanism between shelf and the guide pillar.Guide pillar has four, and respective heights section is provided with screw thread on it, and this section guide pillar is with nut outward.The shelves high guiding mechanism is in the axle sleeve of inversed taper platform shape and the top band by top band external screw thread, bottom that the nut of frustum constitutes in the spiral shell bottom, and sleeve thread section top is that thin neck section, bottom are provided with axial gap; Shelf cover pavilion is in axle sleeve top thin neck section, and the shelves high guiding mechanism is nested with and is fixed in outside the guide pillar.Shelf is installed in the thin neck section draw-in groove of axle sleeve top, and axle sleeve bottom gap dovetail shaped, lower end, gap both sides are provided with plush copper in the arc; The guide pillar outer surface is cooperate with plush copper in the arc wavy from top to bottom.
This shelf of regulating height, by shelves high guiding mechanism set between shelf and the guide pillar, promptly adjust screw thread, nut is adjusted, though simple in structure can the adjustment, but the nut in four bights is operated lifting simultaneously by hand during operation, that is to say that four jiaos can not slide up and down synchronously, therefore use inconvenience, efficient is low.
Application number is that 03274250 Chinese patent (Long Dian Trading Co. company of Guangdong section) discloses a kind of tunable layer frame, comprise a layer frame, refrigeration chamber support strip, also be included in a pair of adjusting rod of described layer frame front end bilateral symmetry pivot dress, be arranged on a pair of bearing pin on the same axis, limit the limited block that described adjusting rod is switched to certain angle, described adjusting rod can be restricted to certain angle around the bearing pin pivot and by described limited block.The new tunable layer shelf structure of this practicality is simple, easy to use, and the low heeling condition in high back can be widely used in the electric equipment products such as refrigerator, refrigerator before layer frame 4 can being adjusted into when the user needs.
This adjustable layer frame is applied in the electric equipment products such as refrigerator, refrigerator, utilizes anterior a pair of adjusting rod, the low heeling condition in high back before being adjusted into, the article that vary in size are limited because of adjustment amount for depositing, and can not adapt to the requirement of depositing the article that vary in size effectively, and adjusting range is very little.
Application number is 200410018644 Chinese patent (Lejin Electronic and Electric Appliance Co Ltd (Tianjin)), the shelf that discloses a kind of refrigerator that can up-down adjustment reserve height is provided with the invention of configuration aspects, is made of shelf, mobile shelf, support bar and power transmission; Can place the inside of the shelf of reserve above at refrigerator; The mobile shelf that can place reserve above can be arranged on the upside of shelf up or down; The lower end hinge of support bar is combined on the shelf, and the upper end that its upper end hinge is combined in mobile shelf is used to support mobile shelf; Transmission of power includes rotating handles, a plurality of rotating shaft, worm and worm wheel etc.Rotating handles is used to produce rotary power; Above-mentioned a plurality of rotating shaft is used to transmit the revolving force that produces by rotating handles; Worm and worm wheel are formed on the end of above-mentioned rotating shaft, with the revolving force of above-mentioned rotating shaft pass to cross one another another rotating shaft of above-mentioned rotating shaft on.
The shelf of this refrigerator that can adjust up and down is provided with structure, mainly be to utilize the change of the support bar angle of two intersections that shelf is moved up and down, the corner dimension of this support bar has certain restriction, therefore adjusting range because of restricted can not be very big, can not adapt to the needs of depositing article of all sizes fully.
Application number is 00213288 Chinese patent (Haier Group, Qingdao Haier Refrigerator Corp. Ltd.) application discloses a kind of adjustable for height refrigerator shelf, it comprises rack, rack is contained in the eyelet of guide rail, a deviator is equipped with in rear end, the base rack back side, deviator is connected with the power shaft of vertically arranging and the output shaft of lateral arrangement, the front end of power shaft is equipped with crank, near the crank place bearing block is installed at power shaft, a roller respectively is equipped with at the output shaft two ends, the roller periphery is provided with the tooth piece that spacing is arranged, above-mentioned tooth piece is inserted in the eyelet of guide rail, near the roller place one bearing block is housed respectively at the output shaft two ends, when need are regulated height, only need outward or rotate counterclockwise, just can make stream wheel scroll-up/down, regulate purpose highly thereby reach with the crank up time.
This adjustable for height refrigerator shelf is adjusted the height of rack by the scroll-up/down of shaking roller, though can reach the adjustment purpose, because this device is located at the rear end at the rack back side, it is not too convenient to operate.
More than the rack of disclosed four kinds of height-adjustable, except weak point separately, the point that a common deficiency is all arranged promptly, all can not take out rack from refrigerator, and rack is an integral body, adjustment is subjected to certain restriction, and is lower to depositing the article fitness that varies in size, when bigger article storage is especially arranged, because rack is got to be come out, and causes large piece article to deposit difficulty.The special for this reason the utility model that proposes.
