In some embodiments, the groove may be provided with a fourth pin hole 115 on a side wall close to the hinge arm structure 3 . The hinged part 22 is provided with an arc ear and a reel. The arc lugs are two sides of the hinge part 22 for abutting against the second end of the torsion spring 12 . The first shaft pin 16 passes through the fourth pin hole 115 and the reel realizes the hinge connection between the connecting structure 2 and the hinge cup structure 1 . Certainly, in some embodiments, other structures may also be used to realize the hinge.

Using this in the above-mentioned embodiment, the first end and the second end of the torsion spring 12 rotate around the torsion spring main body, and when the torsion spring 12 is subjected to an external force, the angles of the first end and the second end of the torsion spring become smaller gradually, Generate torque. This torsional force will generate compressive force on the connecting structure 2 . Specifically, when the door is pushed and closed to about 40-35 degrees, the torsion spring 12 presses the connection structure 2 by pressing against the two sides of the hinge part 22, and the generated pressing force drives the door to take the first pivot pin 16 as the axis Rotate the door shut.

In an optional embodiment, the hinge cup structure 1 provides a damping force for buffering the consistent force of rotating and closing the door.

In some embodiments, the hinge cup structure 1 further includes: a hinge cup body 11 and a damper 13 . The hinge cup body 11 is provided with a groove. The damper 13 is located in the groove; one end faces the inner wall of the groove, and the other end faces the end of the connecting structure.

Through the sliding of the switch part 15, the contact and separation between the convex post 151 and the limiting post 1311 are realized, thereby controlling the movement of the oil cylinder 131. When the convex post 151 is in contact with the limiting post 1311 When in contact, the oil cylinder 131 cannot move relative to the damping rod 132. When the protrusion 151 is separated from the limiting post 1311, the oil cylinder 131 can move relative to the damping rod 132. At this time, the damper 13 is in the working condition. The working state of the damper 13 can be quickly controlled by sliding the switch part 15 .

In some embodiments, the bottom of the limiting column 1311 is a slope. When the limit post 1311 moves close to the oil cylinder 131 , if the oil cylinder 131 approaches the damping rod 132 , it will break through to the back of the slope based on the slope and lean against the limit post 1311 . At this time, the opening and closing of the angle within a certain range will not generate damping force.
