Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in fig. 1 to 7, the damping hinge capable of rotating 360 degrees provided in this embodiment includes a fixed hinge 10 (U-shaped or two L-shaped symmetrically arranged) for fixing a door frame, a movable hinge 20 pivotally connected to the fixed hinge 10 for fixing a door panel, and a rotating shaft 30 (the rotating shaft 30 may be made of a damping material such as nylon, or may be made of a metal material) fixed to the fixed hinge 10 and pivotally connected to the movable hinge 20 for providing a frictional damping force to the rotation of the movable hinge 20, the fixed hinge 10 includes a connecting plate 12 for fixing the door frame and having a first through hole 11 (the first through hole 11 is used for fixing the door frame) on the surface thereof, and two connecting lugs 13 oppositely arranged at two ends of the fixing plate 12, the two connecting lugs 13 are oppositely provided with coaxial second through holes 14, the movable hinge 20 is clamped between the two connecting lugs 13, and the two ends of the two connecting lugs 14 are provided with circular holes 21 coaxial with the second through holes 14, the rotating shaft 30 is fixed in the second through hole 14, and one end of the rotating shaft 30 extends into the circular hole 21, the portion of the rotating shaft 30, which is placed in the circular hole 21, is attached to the inner wall of the circular hole 21 for maintaining and limiting the rotating angles of the movable hinge 20 and the rotating shaft 30 (by using the friction force between the rotating shaft and the movable hinge, the rotating shaft 30 and the circular hole 21 of the embodiment are in interference fit), and the movable hinge 20 is provided with a fixing hole 22 for fixing the door panel along the radial direction.

Based on the structure, the fixed hinge can rotate 360 degrees around the axis of the round hole 21 of the movable hinge 20, so that a larger rotation angle can be formed between the door frame and the door panel in the actual use process; meanwhile, due to the action of the rotating shaft 30, when the fixed hinge 10 and the movable hinge 20 rotate relatively, the friction force of the rotating shaft 30 needs to be overcome, so that after the fixed hinge 10 and the movable hinge 20 rotate to proper positions, the rotating shaft fixes the positions of the fixed hinge 10 and the movable hinge 20; namely, the fixed hinge 10 and the movable hinge 20 are structured to rotate 360 degrees, and the rotation angles of the fixed hinge 10 and the movable hinge 20 are maintained and limited by the friction force of the rotation shaft 30.

In order to ensure the friction force between the rotating shaft 30 and the movable hinge 20, the rotating shaft 30 of the present embodiment is provided with a third through hole 31 along the axial direction of the circular hole 21, and a damping shaft 40 for expanding the rotating shaft 30 along the radial direction is disposed in the third through hole 31. The rotating shaft 30 is expanded by the pressing action of the damping shaft 40 in the third through hole 31, so that the frictional force between the rotating shaft 30 and the movable hinge 20 is ensured; in the process of installation, the rotating shaft 30 can be inserted into the round hole 21 and then the rotating shaft 30 is extruded by the damping shaft 40, so that the installation is convenient; the rotation and positioning of the fixed hinge 10 and the movable hinge 20 are ensured by the action of a suitable damping shaft 40 and the deformation of the rotating shaft can be avoided
