In a specific application, the buffer 2 may be filled with a buffer medium such as hydraulic oil.

The action mechanism of the locking buffer mechanism is as follows:

in use, such as when the door is opened, movement of the rocker arm assembly of the blind hinge rotates the driver 22, thereby rotating the inner barrel 24.

Since the rotation control lever 293 is connected to the inner tube 24, the rotation control lever 293 moves synchronously, and the rotation control lever 293 causes the rotation terminal 292 to slide in translation under the restriction of the rotation chute 2921 and the spline 281 of the slide lever 28, thereby compressing the spring 294. At this time, the hydraulic oil in the inner cylinder 24 flows from one chamber to the other chamber on the side of the rotation terminal 292 and the spring 294.

When the spring 294 is released, the spring 294 pushes the rotary terminal 292 to move towards the locking rod 21, and the rocker arm assembly of the blind hinge moves in the opposite direction to the above process through the mutual cooperation of the rotary control rod 293, the inner cylinder 24 and the driving piece 22, so that the door leaf automatically moves, such as automatically closes. And the rotation speed of the door leaf is controlled through the resistance generated by the hydraulic oil flowing through the channels such as the central hole 2913 and the like.

Moreover, the locking buffer mechanism can adjust the buffer damping force, and the specific operation is as follows: by rotating the adjusting lever 3, the lock-in lever 21 is rotated, and the lock-in control needle 27 is moved in the second direction by the screw-fit of the first fixing member 25. The locking lever 21 drives the locking control needle 27 to change the force by increasing or decreasing the compression amount of the spring 294, and the door closing speed is regulated and controlled by the buffering effect achieved by throttling.
