AI Technical Summary
In automatic door closing structures, there is a risk of collision when the door closes quickly, and existing technologies make it difficult to achieve unobstructed opening while generating damping to adjust the door speed when closing.
A one-way damping adjustable mechanism was designed. By combining a pin shaft with a one-way rotating component, it achieves no damping in one direction and damping in the opposite direction. The damping value can be adjusted by a spring and an adjusting shim. The structure is simple and adjustable.
It effectively reduces the closing speed, avoids the risk of bumps and collisions, and allows for flexible adjustment of the damping value, with a clever and reasonable structural design.

Abstract
Claims
1. A one-way adjustable damping mechanism comprising a first fixed seat, a second fixed seat capable of rotational movement relative to the first fixed seat, and a pin shaft for connecting the first fixed seat and the second fixed seat, characterized in that: A one-way rotating component is fitted on the outer ring surface of the pin. A connecting shaft hole is provided on the first fixed seat. The one-way rotating component is fixedly installed in the connecting shaft hole of the first fixed seat. When the pin rotates relative to the first fixed seat, it is undamped in one direction and damped in the opposite direction. Springs are provided at the connection points between the two ends of the pin and the second fixed seat. The pin rotates relative to the second fixed seat within a certain damping range through the springs. An indefinite number of adjusting shims can be provided between the springs and the second fixed seat.
2. A one-way adjustable damping mechanism according to claim 1, wherein: The pin end is equipped with a backstop nut to prevent the spring from coming out.
3. A one-way adjustable damping mechanism according to claim 2, wherein: An anti-rotation washer with a flat section is provided between the spring and the anti-rotation nut, and the pin is provided with a flat section.
