And a hinge arm structure 3 received in the first receiving groove 2221 and connected to the connecting structure 2, wherein the hinge arm structure 3 has a sliding groove 35 with a downward opening. The hinge arm structure 3 and the connecting structure 2 can be provided with mutually matched connecting modes and components according to requirements. For example, the connection may be made by a second shaft pin 2227 and a third shaft pin 2228.

The hinge arm base 4, which can be fixed on a doorframe or a door, includes a pressing portion 42, and the pressing portion 42 includes a latch 421.

In an assembled state, the hinge arm base 4 is snapped into the sliding groove 35, and the third shaft pin 2228 slides to the latch 421 and is snapped and fixed with the latch 421, so that the hinge arm structure 3 and the hinge arm base 4 are fixedly connected. In the disassembled state, the third shaft pin 2228 and the catch 421 are disengaged, so that the hinge arm structure 3 and the hinge arm base 4 are separated. As shown in fig. 14A to 14D, a user can slide the hinge arm structure 3 on the hinge arm base 4, so that the hinge arm base 4 is accommodated in the sliding groove 35, and further press the position of the third shaft pin 2228, so that the third shaft pin 2228 is engaged with the fastener 421, thereby achieving the rapid installation of the american damping hinge. As shown in fig. 15A to 15D, a user can press the pressing portion 42, so that the fastener 421 is separated from the third axis pin 2228, thereby realizing rapid detachment of the american damping hinge, and further rapidly detaching the door from the corresponding doorframe.

In the above embodiment, the snap 421 in the pressing part 42 is used to engage with or disengage from the third axis pin 2228, so as to mount and dismount the hinge arm structure 3 and the hinge arm base 4.

In an alternative embodiment, the pressing portion 42 further includes: a fourth shaft pin 422 and a third torsion spring 423.

As shown in fig. 3 and 5, the third torsion spring 423 may be a double torsion spring or two or more single torsion springs. And a fourth shaft pin 422, wherein the fourth shaft pin 422 penetrates the third torsion spring 423 in series and is used for hinging the pressing part 42 at one end of the hinge arm base 4. Under the action of external force, the latch 421 rotates to open with the fourth shaft pin 422 as an axis, so that the third shaft pin 2228 is aligned with the latch 421, and under the condition that the external force disappears, the latch 421 rotates back with the fourth shaft pin 422 as an axis under the action of the torque force of the third torsion spring 423, so that the latch 421 is engaged and fixed with the third shaft pin 2228. In the optional embodiment, the structure is simple, so that the disassembly and the installation are more convenient.

In an alternative embodiment, the hinge arm base 4 further comprises a base plate 41; the bottom plate 41 includes: a hook 412 and a contoured cavity 413.

Since the third shaft pin 2228 abuts against the latch 421, the pressing force applied to the latch 421 will cause the pressing portion 42 to rotate around the fourth shaft pin 422 clockwise and open, so that the third shaft pin 2228 falls into the bottom of the shaped cavity 413. At this time, the position of the third shaft pin 2228 is stopped being pressed, the pressing force applied to the buckle 421 disappears, and under the action of the torsion of the third torsion spring 423, the pressing portion 42 rotates counterclockwise around the fourth shaft pin 422 to return to the initial position or close to the initial position, and the semicircular groove 4211 is just clamped into the third shaft pin 2228. The semicircular groove 4211 forms a fixing hole with the shaped cavity 413. The opening size of the fixing hole is smaller than the diameter of the third shaft pin 2228, so that the fixing hole can clamp and fix the third shaft pin 2228, and the American damping hinge can be quickly mounted. As shown in fig. 15A to 15D, a user can press the pressing portion 42, and when the fastening member 421 receives a pressure, the pressing portion 42 rotates clockwise around the fourth shaft pin 422 to open, so that the semicircular groove 4211 is disengaged from the third shaft pin 2228, the fixing hole structure is broken, and the third shaft pin 2228 can be disengaged from the special-shaped cavity 413, thereby achieving quick detachment of the american damping hinge.

Of course, the installer can press the pressing portion 42 to rotate the pressing portion 42 clockwise around the fourth axis pin 422, so that the third axis pin 2228 falls into the bottom of the shaped cavity 413. After the installer loosens the pressing portion 42, under the action of the torsion of the third torsion spring 423, the pressing portion 42 rotates counterclockwise around the fourth shaft pin 422 to return to the initial position or close to the initial position, the semicircular groove 4211 is just clamped into the third shaft pin 2228, the semicircular groove 4211 and the special-shaped cavity 413 form a fixing hole, and the fixing hole is fixedly clamped with the third shaft pin 2228.

The structure in the hinge cup structure 1 will be described.

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

The hinge cup structure comprises: a hinge cup body 11 and a torsion spring.

The torsion spring comprises a torsion spring main body, a clamping jaw and an extension part, wherein the clamping jaw and the extension part are obtained by extending the torsion spring main body; the jaws are fixed in the square holes 112, and the extending portions can be abutted against one end of the connecting structure 2 through the special-shaped holes 113. When the included angle between the hinge cup structure 1 and the connecting structure 2 is in a first range, the extending part is abutted against one end of the connecting structure 2 and generates acting force on the connecting structure 2. There may be a plurality of torsion springs, such as a first torsion spring 12 and a second torsion spring 13, and the first torsion spring 12 and the second torsion spring 13 are respectively located at both sides of the hinge cup body 11. Wherein the first torsion spring 12 is provided with a first jaw 121 and a first extension 122. The second torsion spring 13 is provided with a second jaw 131 and a second extension 132.

Based on the above structure, when the door is pushed to close to an angle of about 40-35 degrees, the first torsion spring 12 and the second torsion spring 13 press the connection structure 2 through the holding arc ear 2112, and the generated pressing force drives the door to rotate and close with the winding drum 2111 as an axis.

In an alternative embodiment, the hinge cup structure 1 provides a damping force that dampens the rotational door closing coherence force.

The hinge cup structure comprises: a reamer body 11 and a damping device 16. The reamer body 11 is provided with a groove 111. A damping device 16, said damping device 16 comprising a damper 162; the damper 162 is located in the groove 111, with one end facing the inner wall of the groove 111 and the other end facing one end of the connecting structure 2; when the included angle between the hinge cup structure 1 and the connecting structure 2 is in the second range, the end of the damper 162 respectively abuts against the inner wall of the groove 111 and the end of the connecting structure and generates a damping force. When the hinge region 211 of the connecting structure 2 contacts one end of the damping device 16 during the door closing process, the damping force of the damping device 16 can buffer the rotational door closing consistency force, so that the door is slowly and softly closed, and the noise generated by the door hitting the door frame is eliminated.

In some embodiments, the damper 162 may include a cylinder and a damping rod, one end of which abuts against the inner wall of the groove 111, and the other end of which is located inside the cylinder. The outer wall of the bottom of the oil cylinder is an inclined plane. When the hinge area 211 of the connection structure 2 contacts the inclined surface of the oil cylinder, thrust is generated to the oil cylinder, and then the oil cylinder is triggered to generate directional damping force, so that the rotation speed of the connection structure 2 of the door is reduced. It should be noted that the inclined plane is provided to help the force to be even, increases the life of attenuator, and then increases the life of device.

It should be noted that a torsion spring or a damping device may be provided in the hinge cup structure 1, or may be provided at the same time. When the door is installed, the door can be driven to rotate and close around the reel 2111 as an axis, and the noise generated when the door impacts the door frame can be eliminated.

Preferably, a protrusion 1621 is disposed on an outer wall of the damper 162; wherein the boss is in contact with the protrusion 1621 when the switch 163 is slid to a first position range, and is separated from the protrusion 1621 when the switch is slid to a second position range.

When the switch 163 slides to the first position range, the protrusion of the switch 163 prevents the damper 162 (oil cylinder) from compressing by the interference protrusion 1621, thereby preventing the rotation of the connection structure 2 and thus the door from rotating. When the switch 163 slides to the second position range, the boss below the switch 163 leaves the protrusion 1621, and the damper 162 (oil cylinder) generates a damping force under the thrust of the hinge region 211 of the connection structure 2 to slow down the rotation of the connection structure 2, but does not prevent the further rotation of the connection structure 2.

In some embodiments, the bottom of the post is beveled. When the convex column moves to be close to the damper 162, if the cylinder of the oil damper 162 is close to the direction of the damping rod, the protrusion 1621 may break through the back surface of the inclined surface based on the inclined surface and abut against the back surface. At this time, the damper 162 does not generate a damping force when opened and closed at an angle within a certain range.

In an optional embodiment, the hinge cup structure 1 further includes a torsion spring protection sleeve, and the torsion spring protection sleeve is sleeved on the torsion spring. There may be multiple torsion spring protection sleeves, such as a first torsion spring protection sleeve 14 and a second torsion spring protection sleeve 15.
