[0028] The inner door handle and the outer door handle are both provided with a rotation locking structure 6, and the two ends of the square shaft are respectively connected and positioned with the two rotation locking structures. In this embodiment, the rotation locking structure can realize locking and unlocking operations.

[0029] In actual application, the rotating locking structure 6 includes a hollow lock shell 61, a connecting mandrel 62 connected to the hollow lock shell, and a rotating seat 63 connected to the connecting mandrel; in this embodiment, the hollow lock shell, the connecting mandrel and the rotating seat can all be metal structures. A rectangular hole 4 is provided at the center of the rotating seat, and a toggle piece 13 is inserted into the rectangular hole. The toggle piece is fixedly connected to the lock core or the knob, and the lock core or the knob drives the rotating seat to rotate through the toggle piece. When the lock core and the knob rotate, the toggle piece moves, thereby driving the rotating seat to rotate.

[0030] A rotating cavity 64 is provided on the side of the hollow lock shell close to the knob or the lock core, and two arc locking grooves 65 are provided on the inner wall of the rotating cavity, and the two arc locking grooves are located at the two ends of the diameter of the rotating cavity. A mounting lug 66 is integrally formed on the outer wall of the hollow lock shell, and the hollow lock shell is fixed to the shell of the inner door handle or the outer door handle by the screw in the mounting lug; in this embodiment, the hollow lock shell is fixed to the shell of the inner door handle or the outer door handle by the mounting lug, and an arc locking groove is provided, which insures the rotating seat by a cylinder to avoid wear of the cylinder and the arc locking groove, and to avoid loss of control of the toggle piece, thereby improving the effectiveness of the opening and closing operation, and having strong applicability and good practicality.

[0031] A toggle block 11 is fixed to the middle of the side surface of the rotating seat 63 near the connecting mandrel, and a cylinder 12 is arranged in the through slot, and the cylinder can be a metal structure or a plastic structure, and the wall thickness of the circular cavity is less than the diameter of the cylinder. That is, by adopting the above structure, the outer side surface of the cylinder can extend out of the outer surface of the circular cavity and snap into the arc locking groove, ensuring the effectiveness of locking and unlocking the cylinder, and the surface of the cylinder in the circular cavity abuts against the edge of the toggle block, and the rotating seat rotates to drive the cylinder to move in the through slot, so that the surface of the cylinder snaps into the arc locking groove to lock or the cylinder retracts into the through slot and is separated from the arc locking groove to unlock.

[0032] A square shaft hole 7 is provided at one end of the connecting core shaft 62 close to the square shaft, and a convex ring 8 is integrally formed at the other end away from the square shaft.

At this time, the outer surface of the cylinder is separated from the arc position groove to achieve locking. After locking, the inner door handle or the outer door handle can be pressed down freely to implement the neutral gear effect. At this time, it is in an empty state and the door cannot be opened, or the edge of the cylinder is in the unlocking groove. At this time, the outer surface of the cylinder is stuck in the arc locking groove to achieve unlocking, and the door can be opened.

[0035] The structural setting of the present invention is reasonable. It can effectively and quickly realize locking or unlocking operation through the rotating locking structure, which is beneficial to improving the convenience of locking. The rotating locking structure includes a hollow lock shell, a connecting core shaft and a rotating seat, and a cylinder is arranged in the through slot hole of the circular cavity.
