In an alternative embodiment, the first connection plate 21 is provided with a through hole 214; the second connecting plate 22 is provided with a round hole 224; the third connecting plate 23 is provided with a first waist-shaped hole 234; the through hole 214, the round hole 224, and the first waist-shaped hole 234 are correspondingly positioned for the passage of the adjusting screw 27. The adjustment of the position between the second connecting plate 22 and the third connecting plate 23 in the third direction can be realized by rotating and adjusting the adjusting screw 27, so that the relative positions of the second connecting plate 22 and the third connecting plate can be quickly adjusted during installation. The length of the first kidney-shaped aperture 234 is adapted to the range of motion in the second direction.

In some embodiments, the strip-shaped mounting portion of the first connecting plate 21 further includes a plurality of passage holes, which may be through, such as a first passage hole, a second passage hole, and a third passage hole. Wherein the first passage hole is aligned with the first through hole 211 for the self-tapping screw 5 to pass through. The second passage hole is aligned with the first and second through holes 212.

In some embodiments, the two sides of the second groove are respectively provided with a first pin hole 225 at one end far away from the hinge cup structure 1; two sides of the third groove are respectively provided with a second pin hole 235 at one end far away from the hinge cup structure 1. The first pin hole 225 and the second pin hole 235 are correspondingly positioned for the first pin 24 to pass through. The first shaft pin 24 can rapidly mount the second connecting plate 22 and the third connecting plate 23 together to form a combined body, and when the connecting structure is assembled, the combined body and the first connecting plate 21 can be conveniently and rapidly combined to form the hinge arm structure 2.

The following describes the structure of the hinge cup structure 1.

In an alternative embodiment, the hinge cup structure 1 provides a pressing force for closing the door.

The hinge cup structure 1 includes: a hinge cup body 11 and a torsion spring 12.

The hinge cup body 11 is provided with a groove, and the side wall of the groove is respectively provided with a fourth through hole 112, a boss 113 and a fifth through hole 114 in sequence; the outer side of the groove is recessed to form an accommodating space corresponding to the boss 113. The torsion spring 12 includes a torsion spring body and first and second ends extending from the torsion spring body; the torsion spring main body is positioned in the accommodating space; the first end and the second end of the torsion spring 12 extend out of the accommodating space; a first end of the torsion spring 12 is provided with a bending extension part, and the bending extension part passes through the fourth through hole 112 and extends into the groove; the second end of the torsion spring 12 abuts against one end of the hinge arm structure 2 through a fifth through hole 114.

When the included angle between the hinge cup structure 1 and the hinge arm structure 2 is in the first range, the second end of the torsion spring 12 abuts against one end of the hinge arm structure 2, and generates an acting force on the hinge arm structure 2.

In some embodiments, the number of torsion springs 12 may be two, wherein one torsion spring 12 is located at one side of the hinge cup structure 1, and the other torsion spring 12 is located at the other side of the hinge cup structure. In order to improve the service life, the torsion spring 12 may further have a torsion spring protection sleeve, where the torsion spring protection sleeve includes two separated parts, a first part is sleeved on the first end, and a second part is sleeved on the torsion spring main body and the second end. The second part comprises a sleeve which is matched with one end of the torsion spring main body, and a shaft post is arranged in the middle of the sleeve and is inserted into a coil of the torsion spring main body.

In some embodiments, the hinge cup body 11 may have two wings on both sides of the groove, and more than two holes 111 may be formed on the two wings, respectively. The hinge cup structure 1 can be fixed to a door or a door frame through the hole 111.

In some embodiments, the recess may be provided with a third pin hole 115 on the side wall adjacent the hinge arm base 3. The hinge part of the first connecting plate 21 is provided with an arc lug and a winding drum. The arc ears are on either side of the hinge for abutting against the second end of the torsion spring 12. The third shaft pin 16 passes through the third pin hole 115 and the winding drum to realize the hinge of the hinge arm structure 2 and the hinge cup structure 1. Of course, in some embodiments, other configurations may be used to effect articulation.

With this, in the above embodiment, the first and second ends of the torsion spring 12 rotate around the torsion spring main body, and when the torsion spring 12 receives an external force, the angles of both the first and second ends of the torsion spring become gradually smaller, generating torsion force. The torsion force will exert a compressive force on the hinge arm structure 2. Specifically, when the door is pushed to about 40-35 degrees, the torsion spring 12 presses the hinge arm structure 2 against two sides of the hinge portion 217, and the generated pressing force drives the door to rotate around the third shaft pin 16 as the axis to close the door.

In an alternative embodiment, the hinge cup structure 1 provides a damping force that buffers rotational door closing penetrability forces.

In some embodiments, the hinge cup structure 1 further comprises: a hinge cup body 11 and a damper 13. The hinge cup body 11 is provided with a groove. A damper 13 is located in the recess; one end faces the inner wall of the groove, and the other end faces one end of the connecting structure. Wherein, when the included angle between the hinge cup structure 1 and the hinge arm structure 2 is in the second range, the end parts of the damper 13 respectively prop against the inner wall of the groove and the end parts of the connecting structure and generate damping force.

When the hinge portion 217 of the hinge arm structure 2 contacts one end of the damper 13 during the door closing process, the damping force of the damper 13 can buffer the rotational door closing penetrability force, so that the door is slowly and gently closed, and noise generated by the door striking the door frame is eliminated.

In some embodiments, the damper 13 includes an oil cylinder 131 and a damper rod 132. One end of the damping rod 132 abuts against the inner wall of the groove, and the other end of the damping rod 132 is located in the oil cylinder 131. The outer wall of the bottom surface of the oil cylinder 131 is a chamfer surface. When the hinge portion 217 of the hinge arm structure 2 contacts the chamfer of the oil cylinder 131, a thrust force is generated on the oil cylinder 131, so that the oil cylinder 131 is triggered to generate a directional damping force, and the rotation speed of the hinge arm structure 2 is slowed down. Therefore, the speed of the rotation of the damper hinge at the time of closing the door can be relieved by the damper 13, and the impact sound generated by the door panel striking the door frame due to the excessively fast rotation speed can be reduced. It should be noted that, the inclined plane is provided with and helps the atress even, increases the life of attenuator, and then increases the life of device. The damper 13 is also called a damping device, and is a device for increasing damping, which is made to quickly attenuate vibration generated when an impact is applied. In some embodiments, the damper 13 may be an oil damper, and common oils include silicone oil, mechanical oil, diesel oil, engine oil, transformer oil, and the oil damper may be made into a plate type, a piston type, a square cone, a cone, etc., and the damper 13 may also be a solid viscous damper, an air damper, a friction damper, etc.

The hinge cup structure 1 may be provided with a torsion spring or a damper, or may be provided with both. When the door is arranged at the same time, the door can be driven to rotate by taking the winding drum as the axis to close the door, and noise generated when the door impacts the door frame can be eliminated.

In an alternative embodiment, a switching function may also be provided, i.e. to fix the door in a specific state. The hinge cup structure 1 further comprises: a fixing portion 14 and a switching portion 15. The fixing portion 14 is covered above the groove, and the shape of the fixing portion 14 is adapted to the shape of the groove, so as to limit the damper 13 from being separated from the groove. A bayonet 141 is provided on one side of the fixing portion 14. The switch 15 is slidably mounted on the bayonet 141 and is provided with a downward projection 151. Correspondingly, a limit post 1311 is further disposed on one side of the damper 13. Wherein the boss 151 is in contact with the limit post 1311 when the switch part 15 is slid to the first position, and the boss 151 is separated from the limit post 1311 when the switch part 15 is slid to the second position.

In some embodiments, the securing portion 14 is provided with a top plate and two hoops 142. Two hoops 142 are located on both sides of the lower portion of the top plate, opposite faces of the two hoops 142 substantially abut against the outer wall of the damper 13, and the space formed by the grooves, the top plate and the two hoops 142 serves to restrain the damper 13 so as to maintain the damper 13 to move in a predetermined path.

By sliding the switch portion 15, contact and separation between the protruding column 151 and the limiting column 1311 are achieved, and movement of the oil cylinder 131 is controlled, when the protruding column 151 contacts with the limiting column 1311, the oil cylinder 131 cannot move relative to the damping rod 132, and when the protruding column 151 separates from the limiting column 1311, the oil cylinder 131 can move relative to the damping rod 132, and at this time, the damper 13 is in a working state. The operating state of the damper 13 can be rapidly controlled by the sliding of the switch portion 15.

In some embodiments, the bottom of the stop post 1311 is beveled. When the limit post 1311 moves closer to the cylinder 131, if the cylinder 131 approaches the damper rod 132, the inclined surface breaks through to the back surface of the inclined surface, and abuts against the limit post 1311. At this time, the angle within a certain range is opened and closed, and no damping force is generated.
