Detailed description of the invention
Seeing Fig. 1, the self-closing structure of a kind of refrigerator doors that the present invention provides, including being arranged on the upper of refrigerator door 1 upper and lower sides
Linkage 2 and lower linkage 3, in order to solve the technical problem described in background technology, in conjunction with Fig. 2-12, the skill of the present invention
Art scheme is, upper hinge mechanism 2 includes that hinge seat 21, upper hinge seat 21 include horizontally disposed seat board 211, and vertically set
Being placed in the jointed shaft 212 of seat board 211, jointed shaft 212 surface being positioned at seat board 211 bottom is arranged with axle sleeve 213, axle sleeve 213
Top outward flanging, supports the bottom surface being located at seat board 211, and the top of refrigerator door 1 is provided with the axial trough 22 relative with jointed shaft 212,
In the axle sleeve 213 partial insertion axial trough 22 of flange bottom, and there is the degree of freedom moved up and down along axial trough 22, the end of axle sleeve 213
Portion is provided with compression spring 23 with filling in the space in axial trough 22 bottom land；Lower linkage 3 includes being arranged on bottom refrigerator door 1
Lower hinge seat 31, and below lower hinge seat 31, be positioned at the supporting hinges seat 32 on front side of refrigerator base angle, lower hinge seat 31 has
The degree of freedom rotated relative to supporting hinges seat 32, lower hinge seat 31 and supporting hinges seat 32 all offers for wearing hinged
The axis hole of axle, the bottom surface of lower hinge seat 31 is provided with upper sliding edge 33 at axis hole, and upper sliding edge 33 includes being positioned at refrigerator door 1
Upper chimb 331 inside and outside the minor face of bottom surface, and the upper concave edge 332 being connected on two between chimb 331, upper chimb 331 with
