Abstract

The utility model provides a refrigerator rack. The utility model is characterized in that the back of the rack is provided with a deviator, an input shaft, and an output shaft, wherein, both ends of the output shaft are respectively provided with a rolling wheel, which is provided with a plurality of gear blocks which are inserted in holes of a slide rail. When the height is regulated, only a rocking bar is rotated clockwise or counterclockwise, the rolling wheels are rolled up and down, and thereby, the purpose of regulating height can be achieved.

Description

Adjustable for height refrigerator shelf

The utility model relates to a kind of refrigerator shelf.

At present, the kind of refrigerator shelf is a lot.In order to satisfy the needs that the user regulates the rack height, many racks are made adjustable.The user regulates the upper-lower position of rack according to the size of chilled food.Yet existing adjustable rack also exists some defectives unavoidably: as a kind of cantilevered rack, when need are regulated upper-lower position, need rack integral body is taken off, the eyelet that hook on it is aimed on the guide rail mounts it again, adjustment process is the integral body eyelet that takes off → find aligning → mount again, and whole process is very much a trouble.Do not comply with one's wishes if once regulate highly, also need repeated removal to mount again.In addition, need during adjusting the food on the rack is taken off, after adjusting finishes, food is put back to again, waste time and energy.People are expecting that the technical scheme that addresses the above problem produces as early as possible.

The utility model is food and the light easy purpose of operation that need not to take off when realizing adjusting on the frame.

In order to achieve the above object, it comprises rack the utility model, rack is contained in the eyelet of guide rail, it is characterized in that: one deviator is housed in rear end, the 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.

Two jiaos of fixedly sliding sleeves of locating respectively to install a U-shaped in the rack rear end.

Described deviator is bevel gear or worm and gear.

The utility model compared with prior art has the following advantages and good effect: 1, because rack has been equipped with power shaft, deviator, parts such as output shaft and roller, when need are regulated height, only need clockwise or rotate counterclockwise with crank, just can make the roller scroll-up/down, thereby reach the purpose of regulating height.2, simple in structure, at a glance can, operate easily easy.3, adjustment process need not to take off the food on the rack, for the user has brought convenience.4, whole adjustment process need not to take off rack, and is time saving and energy saving, and it is arbitrarily convenient to choose adjusting position.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is a upward view of the present utility model.

1, inner bag; 2, guide rail; 3, rack; 4, eyelet; 5, crank; 6, fixing sliding sleeve; 7, bearing block; 8, deviator; 9, power shaft; 10, output shaft; 11, tooth piece; 12, roller; 13, bearing block.

Referring to Fig. 1, Fig. 2, Fig. 3, in centre position, rear end, rack 3 back side speed change gear 8 is housed, it can adopt bevel gear or worm and gear break-in.The power shaft 9 of a vertical layout and the output shaft 10 of lateral arrangement are connected with deviator 8 respectively.At output shaft 10 two ends a roller 12 is installed respectively, several tooth pieces 11 are arranged on the roller 12, tooth piece 11 is inserted in the eyelet 4 on the guide rail 2, and whole rack 3 is installed on the guide rail 2.For power shaft 9, output shaft 10 are supported, be attached with bearing block 13 at power shaft 9 front ends; Near roller 12 places a bearing block 7 is installed respectively at output shaft 10 two ends.In order to prevent that rack 3 from tilting in stable condition time layback, at its two relief angles place fixedly sliding sleeve 6 of a U-shaped is installed respectively, fixedly sliding sleeve 6 can carry out barrier support to it when inclination.

When need are regulated rack 3 height, open crank 5, rotate power shaft 9 (in the clockwise direction, counterclockwise downwards), by deviator 8, output shaft 10 is rotated, drive two rollers 12 and rotate, tooth piece 11 of the tooth piece 11 on the roller 12 (because overlap coefficient is greater than 1) withdraws from before the eyelet 4, contiguous tooth piece 11 has entered eyelet 4, along with the rolling of roller 12, rack 3 moves up and down, thereby reaches the purpose of regulating height.
