During the movement, that is, during the rotation of the movable hinge base 12 from the initial position to the door opening position, the swing shaft 123 swings from the side of the plane where the bottom plate 111 is located away from the cabinet 2 toward the cabinet 2 to the above-mentioned position. The cavity 4, that is, the swing shaft 123 swings from the outside to the inside to the cavity 4, and during this process, the swing shaft 123 and other structures of the refrigeration apparatus 100 do not interfere with each other, so that the swing of the swing shaft 123 does not interfere with each other. Restricted by the fixed hinge base 11, its swing can use the cavity 4 between the cabinet body 2 and the door body 3 to swing the swing shaft 123 until its axis is on the plane where the bottom plate 111 is located, or to swing the swing shaft 123.

Preferably, the connecting member 14 and the fixed hinge base 11 do not interfere with each other. Specifically, it can be achieved by setting the distance between the bottom plate 111 and the base plate 121, so that the swing shaft 123 can smoothly swing from the side of the plane where the bottom plate 111 is located away from the cabinet 2 to the cavity 4, so that the thickness of the hinge 1 can be further made thinner.

Preferably, the main body 143 is recessed away from the bottom plate 111 toward one end of the cabinet body 2 , that is, recessed in the direction away from the cabinet body 2 , so as to avoid interference between the connector 14 and the bottom plate 111 , so that the swing shaft 123 can be smoothly moved to the cavity. 4, even the swing shaft 123 swings into the cavity 4 to a greater extent.

Further, the plane formed by the axes of the pivot shaft 113 and the movable shaft 15 is parallel to the bottom plate 111 , which can also reduce the thickness of the hinge 1 .

Further, when the movable shaft 15 moves to the extreme distal end 1242, the axis of the swing shaft 123 is located on the plane formed by the movable shaft 15 and the axis of the pivot shaft 113. This arrangement can not only make the thickness of the hinge 1 thinner, but also further increase the thickness of the hinge 1. The packing capacity of the refrigeration equipment 100 during transportation, and the supporting effect of the elastic member 17 on the connecting member 14 is maximized, which has the effect of saving effort when opening the door.

In this embodiment, one elastic member 17 is provided; in other embodiments, multiple elastic members 17 can also be provided according to actual needs. On the left and right sides of the member 14, a plurality of elastic members 17 can share the force, so that the size of the elastic members 17 can be reduced, and the outer diameter and wire diameter of the spring 172 can be reduced, so that the thickness of the hinge 1 can be further reduced.

Referring to FIG. 6 , further, the hinge 1 further includes a stopper 13 provided on the fixed hinge base 11 , the stopper 13 is located on the path where the movable hinge base 12 rotates toward the assembly space, and the stopper 13 can resist and move The hinge base 12 limits the rotation angle of the movable hinge base 12 relative to the fixed hinge base 11 , thereby limiting the maximum opening angle of the door body 3 relative to the cabinet body 2 .

In the initial position, the base plate 121 also extends in the up-down direction. During the process of opening the movable hinge base 12 relative to the fixed hinge base 11 from the initial position to the door-opening position, the movable hinge base 12 faces the pivot shaft 113 toward the door. When the assembly space rotates, that is, it rotates outward, when the stopper 13 abuts against the movable hinge base 12, the movable hinge base 12 is in the door opening position, and the stopper 13 restricts the movable hinge base 12 to continue to rotate toward the assembly space. Thus, the door body 3 is suspended. The rotation angle of the movable hinge base 12 relative to the fixed hinge base 11 is limited by providing the stopper 13, thereby limiting the opening angle of the door body 3 and making the door body 3 hover after opening the opening angle.

In practical application, when the door body 3 is opened under the action of external force until the stopper 13 abuts against the movable hinge seat 12, the door body 3 is opened to the set maximum opening angle. Under the action, due to the inevitable gap between the pivot shaft 113, the swing shaft 123 and the various components that are rotatably connected with them, the door body 3 will rebound at a certain angle, so that the movable hinge base 12 is far away from the stopper 13. Distance, it is difficult for the door body 3 to hover at the set maximum opening angle.

In order to solve the above-mentioned technical problems, when the movable hinge base 12 is rotated outward relative to the fixed hinge base 11 to the door opening position, there is a gap between the movable shaft 15 and the extreme proximal end 1241 of the limiting groove 124, and the elastic member 17 has a compressive effect. shape variable. In this way, when an external force is applied to make the movable hinge seat 12 rotate to the door opening position with the door body 3, due to the existence of the gap, the elastic member 17 exerts an upward thrust on the connecting member 14 under the action of its elastic restoring force, and conducts the transmission. To the swing shaft 123, the upward thrust of the connecting piece 14 on the swing shaft 123 is formed, so that the movable hinge base 12 has a tendency to rotate outward around the pivot shaft 113.
