Operation principle of the present utility model is：When refrigerator-freezer lid 4 is in closure state, with Refrigerating cabinet body 5 and hinge
Face on the basis of the face P that shell 12 is fixed, the first dead axle 31, the first moving axis 32, the second dead axle 33, the central point of the second moving axis 34 are away from base
The horizontal range in quasi- face is respectively D1, D2, D3, D4, the point on the basis of the peak E of hinge upper casing 11, the first dead axle 31, first
Moving axis 32, the second dead axle 33, the second moving axis 34 are respectively L1, L2, L3, L4, wherein D2 away from distance between reference<D1、L1<L2, D3<
D4、L3<L4；When needing to open refrigerator-freezer lid 4, refrigerator-freezer lid 4 is pushed up, now hinge upper casing 11 is around the up time of the first dead axle 31
Pin rotates, and drives the first moving axis 32 to rise relative to the first dead axle 31, and transmission handle 21 rises also relative to the first dead axle 31；Pass
Drive driving member 22 to be rotated counterclockwise around the second dead axle 33 while dynamic handle 21 rises, the second moving axis 34 and connecting shaft 35 relative to
Second dead axle 33 rises, and connecting shaft 35 drives connecting rod 23 to rise；In this process, D1, D3 are constant, and D2, D4 change；
L1, L3 are constant, and L2, L4 change, when the first dead axle 31, the first moving axis 32, the second dead axle 33, the second moving axis 34 central point
Away from the distance away from distance between reference by L2<L1, L3<L4 changes to L2=L1, and during L3=L4, D2 is tapered into, D4 by
Gradual change is big, and the arm of force of the central point of 4 the first moving axis of central point distance of refrigerator-freezer lid 32 tapers into, and spring 25 is from being compressed to recovery
Change, this process spring 25 transmit an opposition by connecting rod 23 and driving member 22 to the rotation for being driven handle 21,
This opposition is passed to and covered on hinge by transmission handle 21, in this process, refrigerator-freezer lid 4 open it is relatively difficult, can be with
Avoid because maloperation makes refrigerator-freezer lid 4 be opened；As L2=L1, L3=DL, the spring 25 now compressed restores completely；After
It is continuous to open refrigerator-freezer lid 4, when the first dead axle 31, the first moving axis 32, the second dead axle 33, the second moving axis 34 central point away from datum mark
Distance L2 is changed to by L2=L1, L3=L4>L1, L3>L4 process, D2 are become larger, and D4 is tapered into, refrigerator-freezer lid 4
The arm of force of the central point of the first moving axis of central point distance 32 becomes larger；Spring 25 from reset condition to the state change that is stretched, this
When spring 25 a positive acting power is transmitted to the rotation for being driven handle 21 by connecting rod 23 and driving member 22, now spring 25 is right
The opening procedure of refrigerator-freezer lid 4 plays power-assisted effect, and refrigerator-freezer lid 4 can easily be opened, when the first dead axle 31 is caught in institute
When stating the first locating slot 211, refrigerator-freezer lid 4 is fully opened.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
