Referring to fig. 5 and 7, when the door 3 is switched from the closed state to the open state, the swing shaft 13 moves to the first space 100, a distance is always kept between the swing shaft 13 and the door 3 and the box 2, a door seal 4 is generally required to be arranged between the door 3 and the box 2, and when the first space 100 exists between the door 3 and the box 2 and between the door seal 4, the swing shaft 13 moves from the inside of the hinge 1 to the position of the first space 100, that is, when the door 3 is in the open state, the swing shaft 13 is positioned on the side of the box 2, where the box connecting plate 113 is located; by adjusting the height of the hinge 1 according to the position of the first space 100, the swing shaft 13 can not interfere with other structures of the refrigerator, so that the swing of the swing shaft 13 does not excessively swing due to the limitation of the sliding groove 161 on the sliding shaft 14, the arc-shaped groove of the conventional hinge 1 does not need to be arranged, and the swing of the swing shaft 13 does not occupy the space inside the hinge 1, but the first space 100 of the refrigerator itself is utilized, so that the thickness of the hinge 1 can be further made thinner.
Referring to fig. 2 to 4, the portion of the connecting member 15 between the sliding shaft 14 and the swinging shaft 13 is recessed in a direction away from the case 2, so as to further avoid interference between the connecting member 15 and other structures of the refrigerator when the swinging shaft 13 moves from the inside of the hinge 1 to the first space 100.
Compared with the prior art, the hinge 1 and the refrigerator with the hinge have the following beneficial effects: in the process that the door body connecting seat 12 rotates around the box body connecting seat 11, the hinge 1 limits the elastic supporting part 17 to do linear motion along the direction parallel to the box body connecting plate 113 through the limiting mechanism, so that the problem that the elastic supporting part swings back and forth to occupy a large amount of space in the traditional hinge is avoided, the hinge 1 can be made to be very thin, the strength of the hinge structure is not influenced, the requirement and damage to the elastic supporting part are reduced, the elastic supporting part 17 does not need to swing back and forth and also plays a supporting role, the thinning of the hinge 1 can reduce the storage space of a refrigerator, and the boxing amount in transportation can be made to be larger; the sliding shaft 14 is matched and connected in the sliding groove 161, and the sliding shaft 14 is connected with the swinging shaft 13 through the connecting piece 15, so that the door connecting seat 12 is driven to rotate relative to the box connecting seat 11; the swing shaft 13 and the sliding shaft 14 are sleeved with the shaft sleeves, so that the swing shaft 13 and the sliding shaft 14 can be protected; the two axial ends of the swinging shaft 13 are connected with the pair of second side walls 121 of the door body connecting seat 12, so that the problem of larger hinge thickness caused by the fact that the traditional hinge is provided with an arc-shaped groove and the swinging shaft moves in the arc-shaped groove is avoided, the arc-shaped groove of the traditional hinge is eliminated, the hinge 1 can be made to be very thin and the strength of the structure of the hinge 1 is not influenced, the space required by storage and transportation of the refrigerator is further reduced, and the boxing amount of the refrigerator is increased; the plane formed by the sliding shaft 14 and the rotating shaft 111 is parallel to the box connecting plate 113, or in the process of rotating the door connecting seat 12 around the box connecting seat 11, the swinging shaft 13 swings to the side, facing the box 2, of the plane where the box connecting plate 113 is located, and the swinging of the swinging shaft 13 can use the space between the door 3 and the box 2, so that the thickness of the hinge 1 is reduced, and the box loading amount of a refrigerator during storage and transportation is improved; in the process of overturning the door body connecting seat 12 around the rotating shaft 111 of the box body connecting seat 11, the swinging shaft 13 is driven to do swinging motion, the swinging shaft 13 pulls the connecting piece 15 to drive the sliding shaft 14 to move, the sliding shaft 14 does linear motion under the limit of the limiting part, the sliding end 1711 of the supporting part is further pulled to do linear motion, the problem that a large amount of space is occupied due to the fact that the traditional hinge 1 is provided with an arc-shaped groove and the supporting part swings back and forth is avoided, the hinge 1 can be made to be very thin, the strength of the structure of the hinge 1 is not affected, the supporting part cannot swing back and forth and simultaneously has the supporting effect, the structure inside the hinge 1 is not easy to break away from and damage, the structure of the limiting part can be simpler, the width of a refrigerator can be reduced due to thinning of the hinge 1, and the box loading amount during transportation can be made to be larger.
The above detailed description is merely illustrative of possible embodiments of the present invention, which should not be construed as limiting the scope of the invention, and all equivalent embodiments or modifications that do not depart from the spirit of the invention are intended to be included in the scope of the invention.
