Further, the flange extends from the side edge 122 where the flange is located toward the side plate 112 corresponding to the side edge 122.

Preferably, in this embodiment, the stopping portion 123 includes a pair of flanges, each of the flanges is correspondingly disposed on one of the side edges 122, the pair of flanges extends away from each other and respectively extends toward the side plate 112 corresponding to the side edge 122 where the pair of flanges is located, and the pair of flanges jointly bear the gravity of the door body 3, so that the bearing of each of the flanges can be reduced, and the service life of the flange can be prolonged. In other embodiments, only one of the flanges may be provided.

Referring to fig. 6 to 7 and 9 to 10, further, the side edge 122 is close to one end of the door body hinge base 12, that is, the upper end of the side edge has an arc surface 115, the first position-limiting portion 114 is connected to the arc surface 115 and extends from the arc surface 115 away from the door body hinge base 12 along a tangential direction of the arc surface 115, that is, the first position-limiting portion 114 extends downward from the arc surface 115 along the tangential direction of the arc surface 115, that is, the first position-limiting portion 114 is disposed at one end of the side plate 112 away from the bottom plate 111; when the door body hinge seat 12 is at the door closing position, the stop portion 123 is separated from the arc surface 115, the door body hinge seat 12 can rotate relative to the cabinet body hinge seat 11 without being hindered, and when the door body hinge seat 12 rotates to the set door opening angle, that is, when the door body hinge seat 12 is at the door opening position, the first limit portion 114 abuts against the stop portion 123 to limit the door body hinge seat 12 to continue rotating relative to the cabinet body hinge seat 11, so as to limit the door body 3 to be opened to the set maximum angle, and at this time, the door body 3 can be hovered.

Specifically, referring to fig. 7, in the present embodiment, the upper end of the side plate 112 has a circular arc surface 115, and the flange is separated from the circular arc surface 115 when the door body hinge base 12 is in the door-closing position; when the door body hinge seat 12 is at the door opening position, the flange abuts against the first limiting portion 114. In other embodiments, the first position-limiting portion 114 may also be a protrusion protruding out of the arc surface 115.

Referring to fig. 8, preferably, in an alternative embodiment, the thickness of the end of the cuff near the first stopper portion 114 in the inward and outward direction is greater than the thickness of the end of the cuff far from the first stopper portion 114 in the inward and outward direction, so that the end of the cuff near the first stopper portion 114 can be prevented from being damaged as a main force receiving portion.

Further, one end of the flange facing the first position-limiting portion 114 is arc-shaped, so that damage to the first position-limiting portion 114 when the flange abuts against the first position-limiting portion 114 can be reduced.

Specifically, the end of the flange close to the first limiting portion 114 is bent inward and then along the direction away from the first limiting portion 114, so that the strength of the flange can be improved, the processing difficulty can be reduced, and the processing efficiency can be improved.

In the prior art, when an external force is applied to rotate the door body 3 to the door opening position, the movable shaft 16 drives the elastic member 17 to move to the limit proximal end 1131 of the long groove 113, a downward acting force applied to the movable shaft 16 by the limit proximal end 1131 of the long groove 113 is transmitted to the swing shaft 14 to form a downward outward pulling force of the connecting member 15 on the swing shaft 14, the external force, the gravity of the door body 3, the friction force of the hinge 1 and the pulling force of the connecting member 15 on the swing shaft 14 reach a balance, a contact point of the pivot shaft 13 and the side plate 112 of the cabinet hinge base 11 is located in the upper side of the pivot shaft 13, a contact point of the swing shaft 14 and the door body hinge base 12 is located in the lower side of the swing shaft 14, and a contact point of the swing shaft 14 and the connecting member 15 is located in the upper side of the swing shaft 14; at this time, the external force is removed, since a fit clearance inevitably exists between the pivot shaft 13, the swing shaft 14 and each component rotationally coupled therewith, especially a clearance exists below the swing shaft 14 where the connecting member 15 is coupled with the swing shaft 14, the clearance provides a displacement space for the swing shaft 14 to move downward and outward, under the influence of the gravity of the door body 3, the door body 3 can drive the door body hinge base 12 to rebound, specifically, the contact point of the pivot shaft 13 and the side plate 112 of the cabinet body hinge base 11 is shifted downward along the inner side of the pivot shaft 13, the contact point of the swing shaft 14 and the door body hinge base 12 is shifted upward along the outer side of the swing shaft 14 until the contact point of the swing shaft 14 and the connecting member 15 is shifted to the lower and outward side of the swing shaft 14, at this time, the swing shaft 14 abuts against the connecting member 15 to stop moving, the door body hinge base 12 stops rebounding, and the door body 3 can hover, that is to say, the door 3 cannot hover at the set maximum angle.

To solve the above technical problem, further, when the door body hinge seat 12 rotates outward relative to the cabinet body hinge seat 11 to the door opening position, the stop portion 123 abuts against the first limiting portion 114, so that a first gap is formed between the movable shaft 16 and the proximal limit end 1131 of the elongated slot 113, and the elastic member 17 has a first compression deformation amount. Thus, when the door body 3 is rotated to the door opening position by applying an external force, due to the existence of the first gap, the elastic piece 17 applies an upward thrust to the connecting piece 15 under the action of the elastic restoring force thereof, the upward thrust is transmitted to the swinging shaft 14 to form an upward inward thrust of the connecting piece 15 to the swinging shaft 14, and the contact point of the swinging shaft 14 and the connecting piece 15 is located at the lower side of the swinging shaft 14 and is located at the outer part; when the external force is removed, because the elastic member 17 has the first compression deformation amount, under the action of the elastic restoring force, the elastic member 17 applies an upward thrust to the connecting member 15, and the upward thrust is transmitted to the swing shaft 14 to form an upward inward thrust of the connecting member 15 to the swing shaft 14, so that the contact point of the swing shaft 14 and the door hinge base 12 is located at the upper side inward position of the swing shaft 14, and even under the action of the gravity of the door body 3, a displacement space which moves upward along the inner side relative to the door hinge base 12 cannot be provided for the swing shaft 14, therefore, the problem of rebounding of the door body 3 after the external force is removed is solved, and the door body 3 is suspended at the door opening position, that is, the door body 3 is located at the door opening position when the stopping portion 123 abuts against the first limiting portion 114.

Referring to fig. 4 to 10, further, a second limiting portion 116 is further disposed at an end of the door body hinge seat 11 close to the door body hinge seat 12, the second limiting portion 116 is located on a path of the door body hinge seat 12 rotating inward relative to the door body hinge seat 11 from the door closing position, and the stopping portion 123 can abut against the second limiting portion 116 to limit the door body hinge seat 12 rotating inward relative to the door body hinge seat 11 from the door closing position, so as to prevent the door body hinge seat 12 from rotating back and forth relative to the door body hinge seat 11 to cause abrasion or even damage thereto, reduce a required loading and transporting space, and meanwhile, the position is closer to the door closing position of the door body hinge seat 12, so that the door body hinge seat 12 can be fixed without additional hands or other tools during assembly of a worker, thereby greatly improving the assembly efficiency.

Further, when the door body hinge base 12 rotates inward relative to the cabinet body hinge base 11 by a preset angle from the door closing position, the stop portion 123 abuts against the second limiting portion 116, at this time, a second gap is formed between the movable shaft 16 and the extreme distal end 1132 of the long groove 113, the elastic member 17 has a second compression deformation amount, the second compression deformation amount is larger than the first compression deformation amount, under the action of the elastic restoring force of the elastic member 17, the connecting member 15 provides an upward inward-biased pushing force to the swing shaft 14 so as to push the door body hinge base 12 to continue to rotate inward, while the acting force applied to the door body hinge base 12 by the second limiting portion 116 prevents the door body hinge base 12 from rotating inward, and the movable shaft 16 is close to the extreme distal end 1132 of the long groove 113, and the elastic member 17 has a large compression deformation amount, so that a large elastic restoring force can be provided, under the combined action of the elastic member 17 and the second limiting portion 116, the door body hinge base 12 can be held in this position without rotating inward or outward. The preset angle is not more than 10 degrees, so that the door body hinge seat 12 can keep the preset angle relative to the cabinet body hinge seat 11, the packaging, the transportation and the assembly are convenient, the door body hinge seat 12 is prevented from rotating back and forth relative to the cabinet body hinge seat 11 to cause abrasion and even damage to the door body hinge seat, the required loading and transportation space is reduced, meanwhile, the position is closer to the door closing position of the door body hinge seat 12, the door body hinge seat 12 can be fixed without being additionally held by hands or other tools during the assembly of workers, and the assembly efficiency is greatly improved.

Further, the second limiting portion 116 is a protrusion disposed at the upper end of the hinge seat 11, and the protrusion is disposed on the arc surface 115.

Preferably, one end of the flange close to the side plate 112 is turned towards the protrusion first and then towards the direction far away from the side plate 112, so as to improve the strength of the flange and prolong the service life of the flange.

Each side plate 112 comprises a first section 1121 and a second section 1122 which are sequentially arranged from bottom to top and are connected with each other, the first section 1121 is connected with the bottom plate 111, the second section 1122 protrudes out of the bottom plate 111 and is rotatably connected with the door hinge base 12, a pair of side edges 122 correspond to a pair of side plates 112 one by one, and the second section 1122 of each side plate 112 is rotatably connected with the corresponding side edge 122.
