Example 2
This example is a schematic illustration of example 1:
referring to fig. 6, the track frame 5 has three sides L1, L2 and L3, respectively;
the middle and short outer circular arc edges 41 of the cam 4 are A, B respectively;
A. the circle centers of the B are A1 and B1, and the running tracks of the A1 and B1 are in a regular triangle shape concentric with the track frame 5;
the long outer arc edge 42 in the cam 4 is C (left side between AB) and D (right side between AB) respectively;
the center point of the cam 4 is F 1 ，F 1 The track of (2) is F;
taking the example that the cam 4 rotates anticlockwise in the track frame 5, the track change process is as follows:
1. referring to fig. 6, when the line AB is perpendicular to the line L3, the two ends of A are tangent to the lines L1 and L2 respectively; b is tangent to L3 at the center of the straight line of L3; C. one end of the cam 4 is coincident with the tangential point of the two ends of the cam A, and the other end of the cam C, D is coincident with the tangential point of the cam B, so that the cam 4 is still three tangential points on the L1, the L2 and the L3;
2. referring to fig. 7, cam 4 rotates counterclockwise, when BA line segment and L1 are perpendicular, a is at the center of the straight line of L1, tangential to L1; the two ends of B are tangent to L2 and L3 respectively; C. one end of the cam 4 is overlapped with the tangential point A, and the other end is overlapped with the tangential point B, so that the cam 4 is still three tangential points on the L1, the L2 and the L3;
3. referring to fig. 8, the cam 4 rotates counterclockwise, and when the AB line segment is perpendicular to L2, both ends of a are tangent to L1 and L3, respectively; b is tangential to L2 at the center of the straight line of L2; C. one end of the cam 4 is overlapped with the tangential points of the two ends of the cam A, and the other end is overlapped with the tangential points of the cam B, so that the cam 4 is still three tangential points on the L1, the L2 and the L3;
4. referring to fig. 9, cam 4 rotates counterclockwise, when BA line segment and L3 are perpendicular, a is at the center of the straight line of L3, tangential to L3; both ends of the B are tangent to L1 and L2 respectively; C. one end of the cam 4 is overlapped with the tangential point A, and the other end is overlapped with the tangential point B, so that the cam 4 is still three tangential points on the L1, the L2 and the L3;
5. referring to fig. 10, the cam 4 rotates counterclockwise, and when the AB line segment is perpendicular to L1, both ends of a are tangent to L2 and L3, respectively; b is tangential to L1 at the center of the straight line of L1; C. one end of the cam 4 is overlapped with the tangential points of the two ends of the cam A, and the other end is overlapped with the tangential points of the cam B, so that the cam 4 is still three tangential points on the L1, the L2 and the L3;
6. referring to fig. 11, cam 4 rotates counterclockwise, when BA line segment and L2 are perpendicular, a is at the center of the straight line of L2, tangential to L2; both ends of the B are tangent to L1 and L3 respectively; C. one end of the cam 4 is overlapped with the tangential point A, and the other end is overlapped with the tangential point B, so that the cam 4 is still three tangential points on the L1, the L2 and the L3;
7. and (5) repeating the step 1 and repeating the steps.
As can be seen from the above track change process, when the cam 4 rotates in the track frame 5, three points are always tangential to the track frame 5, so that it can be pushed out, during the rotation of the refrigerator door 1 relative to the refrigerator door 2, the cam 4 on the refrigerator door 1 will rotate in the track frame 5, and during the rotation of the cam 4, as shown in fig. 12, the refrigerator door 1 will retract inwards (in the arrow direction), so that the point F where interference is most likely to occur avoids the interference object.
In contrast to a conventional hinge that rotates about an axis, each point on the hinge of the present solution changes with rotation. Compared with the prior art, the method has the advantages that the limit mode is realized by matching the Lo triangle block with the track frame in a rotating manner, because the Lo triangle block is in contact with the track frame at four points, and the track change is small, the inward retraction amplitude is obviously lower than that of the technical scheme, and therefore, compared with the Lo triangle block, the method can realize the more compact placement of a refrigerator and a deep narrow space or other objects placed in the deep narrow space, thereby not only enabling the occupied space of the refrigerator to be smaller, but also enabling a gap to be smaller and more attractive, being not easy to fall dust, and having the advantages of simple structure and low manufacturing cost from the aspect of production and manufacture.
In addition, if the radius of A, B is set to R, and the radius of C, D is set to R, it can be inferred that if the ratio of R/R is increased, the track change of the refrigerator door 1 is increased, and the inward retraction amplitude is correspondingly increased; conversely, if the R/R ratio is reduced, the track variation of the refrigerator door 1 is reduced and the magnitude of the inward retraction is correspondingly reduced. Can be adaptively adjusted according to the requirements of the refrigerator size and the embedded place.
