Referring to fig. 5 to 7, when the door 3 is rotated from the closed state to the open state, the connection member 15 and the box connection plate 113 do not interfere with each other, so that the swing shaft 13 is prevented from swinging to the first space 100 and being limited.
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 toward a direction away from the box body 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 same have the following beneficial effects: the limiting mechanism limits the rotation angle of the door body connecting seat 12 relative to the refrigerator body connecting seat 11, so as to limit the opening angle of the door body 3 of the refrigerator relative to the refrigerator body 2, so that the door body 3 can hover after being opened at a certain angle, and a user can conveniently store and take articles; 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, and the problem that the elastic supporting part swings back and forth in the traditional hinge to occupy a large amount of space is avoided, so that the hinge 1 can be made very thin, the strength of the hinge structure is not influenced, the requirement and the damage to the elastic supporting part are reduced, the elastic supporting part 17 does not need to swing back and forth and also has a supporting function, the storage and transportation space of the refrigerator can be reduced due to the thinning of the hinge 1, and the boxing amount in transportation can be made 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 body connecting seat 12 is driven to rotate relative to the refrigerator body connecting seat 11, the movement amplitude of the sliding shaft 14 is limited through two ends of the sliding groove 161, and the rotating angle of the door body connecting seat 12 relative to the refrigerator body connecting seat 11 and the opening angle of the door body 3 of the refrigerator relative to the refrigerator body 2 are limited; the shaft sleeves are sleeved outside the swinging shaft 13 and the sliding shaft 14, so that the swinging shaft 13 and the sliding shaft 14 can be protected, noise in the using process and abrasion to the swinging shaft 13 and the sliding shaft 14 are reduced, the service lives of the hinge 1 and the refrigerator are prolonged, and the use experience of a user is improved; the pair of second side walls 121 of the door body connecting seat 12 are connected through the two axial ends of the swinging shaft 13, and a gap is formed between the swinging shaft and the pair of first side walls 112 of the box body connecting seat 11, so that the problem that the thickness of the hinge is larger due to the fact that the traditional hinge is provided with an arc-shaped groove and the swinging shaft moves in the arc-shaped groove is solved, the arc-shaped groove of the traditional hinge is eliminated, the hinge 1 can be made to be very thin, the strength of the structure of the hinge 1 is not influenced, the required space during storage and transportation of the refrigerator is further reduced, and the box loading amount of the refrigerator is increased; by enabling the plane formed by the sliding shaft 14 and the rotating shaft 111 to be parallel to the box body connecting plate 113, or enabling the swinging shaft 13 to swing to the plane where the box body connecting plate 113 is located in the process that the door body connecting seat 12 rotates around the box body connecting seat 11, or swing to one side, facing the box body 2, of the plane where the box body connecting plate 113 is located, of the box body connecting seat, the swinging of the swinging shaft 13 can use the space between the door body 3 and the box body 2, so that the thickness of the hinge 1 is reduced, and the box loading amount of the refrigerator during storage and transportation is increased; door body connecting seat 12 is round the in-process of box connecting seat 11's pivot 111 upset motion, it is swing motion to drive oscillating axle 13, oscillating axle 13 draws connecting piece 15 to drive sliding shaft 14 motion, sliding shaft 14 is linear motion under the restriction of spacing portion, further draw the sliding end 1711 of supporting part to be linear motion, avoided traditional hinge 1 to set up the arc wall and the problem that the supporting part was swung around and occupied a large amount of spaces, thereby can be done very thin and do not influence the intensity of hinge 1 structure with hinge 1, the supporting part can not produce the problem that still needs to play the supporting role in the swing around, make the structure of hinge 1 inside be difficult for breaking away from and damaging, the structure of spacing portion can be simpler, and the attenuation of hinge 1 can make the width reduction of freezer, the packing volume during transportation can be done bigger.
The detailed description set forth above is merely a specific description of possible embodiments of the present invention and is not intended to limit the scope of the invention, which is intended to include within the scope of the invention equivalent embodiments or modifications that do not depart from the technical spirit of the present invention.
