In the prior art, when an external force is applied to rotate the door body 3 to the opening position, the movable shaft 16 drives the elastic member 17 to move to the extreme proximal end 1131 of the long groove 113 , and the extreme proximal end 1131 of the long groove 113 acts on the movable shaft 16 . The downward force is transmitted to the swing shaft 14 to form a pulling force of the connecting piece 15 to the swing shaft 14 downward and outward. The contact point between 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, and the contact point between the swing shaft 14 and the door hinge base 12 is located on the side of the swing shaft 14. The lower side is outward, and the contact point between the swing shaft 14 and the connecting piece 15 is located in the upper side of the swing shaft 14; at this time, if the external force is removed, since the pivot shaft 13, the swing shaft 14 and the various components that are rotated and matched with it cannot be Avoid the existence of a matching gap, especially there is a gap at the lower and outer part of the swing shaft 14 where the connecting piece 15 and the swing shaft 14 are mated. This gap provides a displacement space for the swing shaft 14 to move to the lower and outer part. Under the influence of gravity, the door body 3 will drive the door hinge base 12 to rebound. Specifically, the contact point between the pivot shaft 13 and the side plate 112 of the cabinet hinge base 11 is shifted downward along the inner side of the pivot shaft 13, and the swing shaft 14 The contact point with the door hinge base 12 is shifted upward along the outer side of the swing shaft 14 until the contact point between the swing shaft 14 and the connecting piece 15 is transferred to the lower side of the swing shaft 14 and outside, and the swing shaft 14 is against the connecting piece. 15 thus stops moving, the door hinge seat 12 stops rebounding, and the door 3 can hover, that is, the door 3 cannot hover at the set maximum angle.

In order to solve the above-mentioned technical problems, further, when the door hinge base 12 is rotated outward relative to the cabinet hinge base 11 to the door opening position, the stopper 123 abuts against the first limit part 114, and at this time, the movable shaft 16 There is a first gap between it and the extreme proximal end 1131 of the long groove 113, and the elastic member 17 has a first amount of compression deformation. In this way, when an external force is applied to rotate the door body 3 to the opening position, due to the existence of the first gap, the elastic member 17 exerts an upward thrust on the connecting member 15 under the action of its elastic restoring force, and transmits it to the swing shaft. 14 forms the thrust of the connecting piece 15 to the swing shaft 14 upward and inward, and the contact point between the swing shaft 14 and the connecting piece 15 is located at the lower side of the swing shaft 14 and outward; when the external force is removed, because the elastic member 17 has the first compression The amount of deformation, under the action of its elastic restoring force, the elastic member 17 exerts an upward thrust on the connecting member 15, and is transmitted to the swing shaft 14 to form a thrust force of the connecting member 15 to the swing shaft 14 upward and inward, so that the swing shaft 14 and the door body The contact point of the hinge seat 12 is located at the upper and inner side of the swing shaft 14. Even under the action of the gravity of the door body 3, the swing shaft 14 cannot provide a displacement space for the swing shaft 14 to move upward relative to the door body hinge seat 12 along the inner side. Therefore, the solution is to solve the problem. To avoid the problem of the door body 3 rebounding after the external force is removed, 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 stopper 123 abuts the first limiting portion 114 .

4 to 10 , further, one end of the cabinet hinge base 11 close to the door hinge base 12 is further provided with a second limiting portion 116 , and the second limiting portion 116 is located at the door hinge base 12 from the door closing position.

At the same time, the position is relatively close to the door hinge seat 12. During assembly, the hinge seat 12 of the door body can be fixed without holding the hinge seat 12 by hand or other tools, which greatly improves the assembly efficiency.

Further, when the door hinge seat 12 is rotated inward by a preset angle relative to the cabinet hinge seat 11 from the door closing position, the stopper portion 123 abuts the second limit portion 116 , and the movable shaft 16 and the long slot 113 are in contact with each other. There is a second gap between the extreme distal ends 1132 , the elastic member 17 has a second amount of compression deformation, and the second amount of compression deformation is greater than the first amount of compression deformation. Under the action of the elastic restoring force of the elastic member 17 , the connecting member 15 provides an upward and inward thrust to the swing shaft 14 to push the door hinge seat 12 to continue to rotate inward, while the force exerted by the second limiting portion 116 on the door hinge seat 12 prevents the door hinge seat 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 amount of compression deformation, so it can provide a large elastic restoring force. The door hinge seat 12 can remain in this position without turning inward or outward. The preset angle is not greater than 10°, so that the door hinge base 12 can maintain the preset angle relative to the cabinet hinge base 11, which is convenient for packaging, transportation and assembly, and avoids the door hinge base 12 going back and forth relative to the cabinet hinge base 11 Rotation will cause wear or even damage to it, reducing the required loading and transportation space, and at the same time, this position is relatively close to the door closing position of the door hinge seat 12, and workers do not need to use hands or other tools to hold the door when assembling The body hinge seat 12 can be fixed, which greatly improves the assembly efficiency.
