Alternatively, one end of the fourth link 204 is rotatably connected to the middle position of the third link 203, and the other end is bent upward to be flush with one end of the first link 201 connected to the housing mount 100. Thus, the fourth connecting rod 204 is connected to the door body connecting seat 300 at the same level as the first connecting rod 201 at the same level as the first connecting rod 100, so that the moment is reduced, the stability of rotation connection is maintained, and the overall bearing capacity of the hinge is improved.

As shown in fig. 4, optionally, wear plates 400 are disposed between the connection points of the box mount 100 and the link assembly 200, and between the connection points of the plurality of links of the link assembly 200. Thus, wear-resisting plates 400 are arranged at the connecting positions of the connecting rods in the connecting rod assembly 200 and the connecting positions of the connecting rods and the box body mounting seat 100, connecting gaps are filled by the wear-resisting plates 400, the effects of lubrication and wear resistance are achieved under the condition that the connecting rods and the box body mounting seat 100 rotate, the wear among the connecting rods is reduced, the rotating stability of all the positions is improved, the connecting rods are prevented from shaking, the bearing capacity of the hinge is maintained, and the stability and the durability of the hinge are improved.

Optionally, the wear pad 400 includes: pad type wear pad. The pad type wear plates are clamped between the connection points where the links are rotatably connected to each other and between the links and the case mount 100. Like this, adopt gasket formula wear pad setting between two connecting rods that are connected each other, make wear pad 400 itself for two connecting rods all rotatable, can further improve the pivoted resistance between two connecting rods, improve the smoothness nature of mutual pivoted between the connecting rods, and also can play better stand wear and tear effect.

Optionally, the pad-type wear pad is a circular sheet. Thus, the wear pad 400 can be better rotated between the two connecting rods, corners are smooth, abrasion to the connecting rods is prevented, the wear-resisting effect is further improved, and better lubricity is achieved.

Optionally, the diameter of the pad wear plate is the same as the width of the connecting rod. Like this, can improve the supporting effect of the connecting rod that is located the downside to the connecting rod that is located the upside, prevent that pad formula wear pad area of contact from being too little, cause the connecting rod atress inhomogeneous lead to damaging, improve the holistic effect of hinge.

Optionally, the wear pad 400 is made of copper. Thus, the copper material is smooth, has good wear resistance, can effectively reduce wear, and enables the rotation between the connecting rods and the box body mounting seat 100 and the door body connecting seat 300 to be smoother.

Alternatively, the linkage assembly 200 is provided with two sets, and the two sets of linkage assemblies 200 are connected to the same housing mount 100. Therefore, the refrigerator is generally provided with the upper door and the lower door, two groups of hinges are generally required to be installed at the beam position, and the two groups of connecting rod assemblies 200 are arranged to share the same box installation seat 100, so that the thickness of the side wall of one layer of box installation seat 100 can be reduced, the installation space is more fully utilized, the thickness of the middle beam can be reduced, the occupation of the optimal storage position in the refrigerator is further reduced, and the storage space of the refrigerator is optimized.
