Description

A kind of refrigerator equipped with mute guide rail and mute drawer

Technical field

The utility model relates to refrigerator art, more specifically a kind of ice equipped with mute guide rail and mute drawer Case.

Background technique

The predominantly following three kinds of modes of relative motion (pull) between the guide rail and drawer used in refrigerator at present:

1, the form of drawer direct sliding friction on guide rail；Such mode in use, if food in drawer More, then it is very big to push and pull sound, reduces product specification, and idler wheel is directly on guide rail, and it is big to shake abnormal sound, transports and makes With easy to fall off in the process；

2, the form of Metal Contact Rollers guide rail and drawer cooperation with bearing or ball；Currently, in the market ten thousand yuan it is below Refrigerator using this Metal Contact Rollers add rubber ring guide rail with drawer is mute matches, such guide rail, which is adopted, to be screwed, mounting means It is relatively complicated, the risk for having surface corrosion is used for a long time；

3, the form of three connector guide rails；Currently, ten thousand yuan or more of refrigerator is mute using three connector guide rails in the market, it is such to lead Rail weight weight, need to install built-in fitting, and adopt and be screwed before foam box, then drawer is snapped fitted on guide rail again, peace Dress operation is quite cumbersome and inconvenient, complex process and cost is very high.

Utility model content

The utility model is intended to solve one of above-mentioned technical problem at least to a certain extent.For this purpose, the utility model mentions A kind of refrigerator equipped with mute guide rail and mute drawer out, to can preferably meet, user is mute to household appliances noise reduction to be made With demand, while simplifying production technology, making it easier to assembly operation, achievees the purpose that cost efficiency.

To achieve the above objectives, the present invention adopts the following technical solutions:

A kind of refrigerator equipped with mute guide rail and mute drawer, a pair of mute guide rail are symmetrically mounted on cabinet liner or so Side, the left and right sides of mute drawer pass through respectively a pair of of roll wheel assembly realize on a pair of mute guide rail can front and back pull, described one To the structure setting of roll wheel assembly are as follows:

First roll wheel assembly is made of the first rubber ring, the first idler wheel and the first roller shaft, and first roller housing is loaded on It on first roller shaft, can be turned round by axis of the first roller shaft, first rubber ring is flush-mounted in the first idler wheel periphery In annular groove, bared end be in contact with the sliding slot upper and lower end face of mute guide rail, first roll wheel assembly is with the first roller shaft Buckle end be installed on the bayonet in mute drawer side surface sliding rail rear end portion；

The contour structures of second roll wheel assembly are identical as the first roll wheel assembly, and be installed on identical structure type it is quiet The side front end portion of sound guide rail, support is in the front bottom end of mute drawer side surface sliding rail under original state；

The mute drawer is that the sliding slot with the first idler wheel along mute guide rail rolls, and relies on and second on the second idler wheel Being in rolling contact between rubber ring, realizing can front and back pull on a pair of mute guide rail.

The design feature of the utility model is lain also in:

First roller shaft is installed in the structure setting on mute drawer are as follows:

The buckle end of first roller shaft is in " Contraband " shape, and open end two sides are symmetrically arranged with a pair of of the grab turned down outward, The left and right sides of the mute drawer is symmetrically arranged with a pair of of sliding rail, and the rear end of any sliding rail is equipped with bayonet, and the first roller shaft is It is closely inserted in bayonet with closed end, bayonet outer is set to the grab hook of open end two sides.

The front end of the mute drawer side surface sliding rail has convex segmental arc, the position under original state with the second idler wheel It is corresponding, be covered on by gravity on the periphery of the second rubber ring, realize the second roll wheel assembly to the support of mute drawer.

The mute guide rail card is loaded on lining in refrigerator body.

Or, the mute guide rail is to be installed in lining in refrigerator body by screw.

Compared with the prior art, the utility model has the beneficial effect that:

1, the refrigerator of the utility model be realized by a pair of of roll wheel assembly the mute relatively mute guide rail of drawer can pull, should A pair of of roll wheel assembly construction profile is identical, be using idler wheel and roller shaft split-type design, and roller shaft be installed in it is quiet On sound guide rail or mute drawer, realizing can unify to exchange between a pair of of roll wheel assembly, can reduce due to cannot be used interchangeably and Lead to no mistake proofing installation and the excessive deficiency of components, versatility is good, and idler wheel will not fall off in transport and use process, mention The quality and class for having risen product, reduce costs, and improve product core competitiveness；

2, the mute guide rail of the utility model refrigerator and mute drawer overall structure are simple, can simplify production technology, easily In assembly operation, hand labor load is alleviated, production efficiency is improved, can preferably meet user to household appliances noise reduction Mute use demand improves user to the favorable comment degree of product, promotes consumption experience sense and purchase of the consumer in purchasing process Buy intention.
