Abstract
A slow retraction mechanism, a locking-type slow retraction device and a winding device. The slow retraction mechanism fits with a winder including a main shaft and a main body rotatably sleeved thereon. The main body can rotate around the main shaft to wind or unwind flexible materials. The slow retraction mechanism includes a blocking part, a decelerating part rotatably arranged on the main body, and an elastic part arranged on the main body and connected with the decelerating part. When the main body rotates around the main shaft in a first direction to wind the flexible material, the decelerating part rotates relative to the main body along a second direction opposite to the first direction to approach the blocking part to rub against the blocking part to reduce a rotation speed. The elastic part applies an elastic force to hinder the decelerating part from rotating along the second direction.
