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.

Abstract: The present invention relates to an electric retracting hose & cord reel. A reel body is connected with a driving motor through a driven gear and a driving gear. The driving gear is provided with an arresting disc and a locking device corresponding to the arresting disc. The driving motor and an electromagnet in the locking device are connected with a control plate. The control plate is connected with a locking switch and a motor on-off switch on an arresting block. The locking switch controls the electromagnet through the control plate to act. The motor on-off switch controls the driving motor through the control plate to be started and stopped.
