Specific embodiment
Referring to Fig. 1, a kind of self-closing structure of refrigerator doors provided by the invention, including the upper of 1 upper and lower sides of refrigerator door is arranged in
Linkage 2 and lower hinge mechanism 3, in order to solve technical problem described in background technology, in conjunction with Fig. 2-12, skill of the invention
Art scheme is that upper hinge mechanism 2 includes upper hinge seat 21, and upper hinge seat 21 includes horizontally disposed seat board 211, and is vertically set
It is placed in the articulated shaft 212 of seat board 211,212 surface of articulated shaft positioned at 211 lower part of seat board is arranged with axle sleeve 213, axle sleeve 213
Top outward flanging, to the bottom surface for being located at seat board 211, the top of refrigerator door 1 is equipped with the axial trough 22 opposite with articulated shaft 212,
In the 213 partial insertion axial trough 22 of axle sleeve of flange lower part, and there is the freedom degree moved up and down along axial trough 22, the bottom of axle sleeve 213
Filling is equipped with compressed spring 23 in space in portion and 22 slot bottom of axial trough；Lower hinge mechanism 3 includes being arranged in 1 bottom of refrigerator door
Lower hinge seat 31 and the lower section of lower hinge seat 31, the supporting hinges seat 32 on front side of refrigerator base angle, lower hinge seat 31 have
Relative to the freedom degree that supporting hinges seat 32 rotates, offered on lower hinge seat 31 and supporting hinges seat 32 hinged for wearing
