When the movable hinge base 12 is opened from the initial position to the door opening position with respect to the fixed hinge base 11, the movable hinge base 12 rotates around the pivot shaft 113 toward the assembly space, that is, rotates outward, until the stopper 13 abuts against the movable hinge base 12, the movable hinge base 12 is at the door opening position, and the stopper 13 limits the movable hinge base 12 to continue rotating toward the assembly space, so that the door 3 is suspended. The stop piece 13 is arranged to limit the rotation angle of the movable hinge base 12 relative to the fixed hinge base 11, so as to limit the door opening angle of the door body 3 and enable the door body 3 to hover after opening the door opening angle.

In practical application, when the door body 3 is opened to the stop piece 13 to abut against the movable hinge seat 12 under the action of external force, the door body 3 is opened to a set maximum door opening angle, and after the external force is removed, under the action of the gravity of the door body 3, because the pivot shaft 113, the swing shaft 123 and the parts in rotation matching with the pivot shaft inevitably have fit gaps, the door body 3 has resilience at a certain angle, so that the movable hinge seat 12 is far away from the stop piece 13 by a certain distance, and the door body 3 is difficult to hover at the set maximum door opening angle.

To solve the above technical problem, when the movable hinge base 12 is rotated outward relative to the fixed hinge base 11 to the door-opening position, a gap is formed between the movable shaft 15 and the proximal limit end 1241 of the limiting groove 124, and the elastic element 17 has a compression deformation amount. Thus, when the external force is applied to rotate the hinge base 12 to the door opening position along with the door body 3, due to the existence of the gap, the elastic member 17 applies an upward thrust to the connecting member 14 under the action of the elastic restoring force thereof, and transmits the upward thrust to the swinging shaft 123 to form an upward thrust of the connecting member 14 to the swinging shaft 123, so that the hinge base 12 has a tendency of rotating outward around the pivoting shaft 113, and even if the external force is removed, the thrust can form a balance with the gravity of the door body 3, so that the door body 3 hovers at the set maximum door opening angle, and the problem of rebound of the door body 3 after the external force is removed is solved.

Specifically, the stop member 13 is disposed on the side plate 112 and protrudes from the side plate 112 toward the assembly space, the stop member 13 is located on a path of the side edge 122 corresponding to the side plate 112 where the stop member 13 is located toward the assembly space, and when the movable hinge base 12 rotates outwards around the pivot shaft 113 until the stop member 13 abuts against the side plate 112, the side plate 112 can limit the movable hinge base 12 from continuing to rotate outwards.

The sleeve 181 may be cylindrical. Preferably, referring to fig. 8 to 9, the cross section of the setting sleeve 181 is arc-shaped, and the central angle thereof is 270 to 280 °. Therefore, the sleeve 181 is arranged to be in a semi-closed opening structure, the shaft sleeve 18 can be directly clamped on the swing shaft 123, the movable shaft 15 and the pivot shaft 113 along the radial direction, the assembling efficiency is improved, the limitation of the assembling sequence is avoided, and all parts are prevented from being disassembled and reassembled when the assembling sequence is wrong.

Further, the oil storage rib 182 extends along the axial direction of the sleeve 181, the oil storage rib 182 is provided with at least two, and the at least two oil storage ribs 182 are evenly arranged along the circumference of the sleeve 181, so that the speed of lubricating oil seeping out from the shaft sleeve 18 can be delayed, and the problems that the hinge 1 is dirty and lubricating oil needs to be frequently added due to excessive overflow of the lubricating oil are avoided.
