Word is described.
According to an aspect of the present invention, a kind of refrigerator door height adjustment device is provided, wherein the refrigerator door is high
Degree regulating device includes holder 10, shaft 20 and elevating mechanism 30, and the holder 10 is used for the babinet mounted on refrigerator, described
Shaft 20 is rotatably installed on the holder 10, and cam 40 is fixed in the shaft 20 and is equipped with operating parts 50, described
Elevating mechanism 30 include be used to support the refrigerator door body lifting unit 31 and be connected to the lifting unit 31 and with it is described convex
The joint portion 32 of 40 cooperation of wheel.
Operating parts 50 is mounted in the shaft 20 in lifting direction, thus is arranged in refrigerator door height adjustment device
Side so that when operation convenient for observation, improve user satisfaction.
Wherein, when in use, shaft 20 can be driven to rotate so that cam 40 follows shaft by rotating operating parts 50
20 rotate and joint portion 32 and lifting unit 31 are driven to move up and down, to adjust the height for being supported on the door body on lifting unit 31.
Joint portion 32 can be various forms appropriate, and the progress of lifting unit 31 is connected to as long as can match to merge with cam 40
Transmission.To simplify structure, joint portion 32 can be rod-like element 321, for the transmission for providing stable, the extension of rod-like element 321
Direction is the moving direction of elevating mechanism 30.In addition, to ensure that elevating mechanism 30 only moves along the vertical direction, it can be by appropriate
Mode limit elevating mechanism 30 other directions degree of freedom.Preferably, rod-like element 321 can be set across the holder 10
It sets, to limit the degree of freedom in other directions of rod-like element 321 by holder 10.
In addition, including being arranged in the end of the rod-like element 321 for ease of coordinating the rotation of cam 40, the joint portion 32
Counterpart 322, the counterpart 322 has the cylindrical surface that is contacted with the outer surface of the cam 40.Cam 40 and match as a result,
Component 322 can be in rolling contact each other, improve the accuracy and stability of transmission.
Wherein, rod-like element 321 and counterpart 322 can be individual component and be fixedly installed togather, alternatively, to simplify
Installation, rod-like element 321 and counterpart 322 can be integrated.It is highly preferred that rod-like element 321, counterpart 322 and lifting unit 31
It may be integrally formed.Wherein, to provide door body firm support, lifting unit 31 can be the knot with larger bearing area
Structure, such as can be tabular.
In the present invention, holder 10 can be arranged as required to as various appropriate ways, as long as being easily installed babinet and just
In the setting of cam 40 and joint portion 32.For example, as shown in figs. 1,2 and 6, the holder 10 includes opposite side wall
11 and the roof 12 of the side wall 11 is connected, the rod-like element 321 passes through the setting of the roof 12, the shaft 20 to be installed on phase
To the side wall 11.Holder 10 can be installed on babinet by side wall 11 as a result, and be realized by cam 40 and joint portion 32
The lifting of lifting unit 31.
In addition, for ease of operating the operating parts 50 from side, holder 10 can be formed such that operating parts 50 can be sudden and violent
