The working process and principle are as follows: when in use, the device is arranged on a door frame, the rotating pin 15 is arranged on a door, and the driven rotating mechanism 5 rotates along with the opening and closing of the door;

when the door is opened (in the process of the state from fig. 2 to fig. 4), the rotating pin 15 rotates, so that the shaped cam 14 rotates, and the shaped cam 14 is always abutted against the buffer block 13 in the rotating process, so that the buffer block 13 and the slide block 8 move in the chamber 7 and compress the spring 12, therefore, in the opening process of the door, the resistance of the buffer block 13, the slide block 8 and the spring 12 needs to be overcome, so as to reduce the speed, meanwhile, when the slide block 8 moves, the pipe gap 27 is increasingly large in volume, the cavity two 26 is small in volume, the flow channel four 25 of the reversing element 22 can be communicated with liquid, so that the liquid in the cavity two 26 flows from the flow channel two 21 to the flow channel four 25 to the cavity one 19, the flow channel one 18 and the pipe gap 27 (as shown in the arrow direction of fig. 5), therefore, the door also needs to overcome the resistance of the liquid in the rotating process, further reduces the speed, and is helpful for reducing the resonance amplitude of each mechanical element in the device, the damage of mechanical elements is reduced, and the service life of the device is prolonged;

when the door is closed, the rotating pin 15 rotates, so that the special-shaped cam 14 rotates, the buffer block 13 and the sliding block 8 move in the chamber 7, the spring 12 is gradually reset due to the self-restoring force, meanwhile, when the sliding block 8 moves, the size of the pipe gap 27 is smaller and smaller, and the flow channel four 25 of the reversing element 22 cannot be communicated with liquid, so that the liquid in the cavity I19 and the pipe gap 27 flows to the cavity II 26 through the flow channel eight 32, the flow channel five 30, the flow channel six 31, the abdicating hole 33 and the flow channel seven 23 (as shown in the arrow direction in fig. 3), and the size of the cavity II 26 is gradually increased, so that the spring 12 is gradually reset, and the resistance of the liquid needs to be overcome while the sliding block 8 moves.

The customer needs to adjust the damping effect by changing the size of the adjustment element 29 and changing the flow of liquid between the blocked flow channel six 31 and the flow channel seven 23.

According to the invention, the driven rotating mechanism 5 is arranged to drive the buffering mechanism 4 to move, namely the rotating pin 15 rotates to drive the special-shaped cam 14 to rotate, and the special-shaped cam 14 is always abutted against the buffering block 13 in the rotating process, so that the resistance of the buffering block 13, the sliding block 8 and the spring 12 needs to be overcome when the door rotates, the speed is reduced, and the impact on the door and a door frame is reduced; by arranging the liquid loop 6 in the buffer mechanism 4, when the door is opened, the liquid flows in the direction that the liquid in the cavity II 26 flows into the cavity I19, the flow channel I18 and the pipe gap 27 (as shown in the arrow direction in fig. 5), and when the door is closed, the liquid flows in the direction that the pipe gap 27, the flow channel I18 and the liquid in the cavity I19 flow into the cavity II 26 through the flow channel eight 32, the flow channel five 30, the flow channel six 31, the abdicating hole 33 and the flow channel seven 23 (as shown in the arrow direction in fig. 3).
