The invention relates to the technical field of door curtains, and discloses a reset slow swing mechanism of a door curtain. The mechanism comprises a curtain body; an air storage cavity is formed in the upper end of an inner cavity of the curtain body and is in an inverted U shape; an inflation groove is formed in the middle of the inner cavity of the curtain body and is in an inverted T shape; the upper end of the inflation groove communicates with the lower end of the middle of the air storage cavity; and the middles of the two sides of the air storage cavity are movably sleeved with piston blocks. By arranging the reset slow swing mechanism, when the door curtain is normally opened, the piston blocks move upwards under the action of upward thrust, so that air in the air storage cavity is continuously squeezed into the inflation groove, the pressure intensity in the inflation groove is increased, and the lower end of the door curtain is straightened; and when the door curtain is automatically reset, the swinging efficiency of the door curtain is reduced through the straightened lower end of the door curtain, so that the situation that the lower end of the door curtain is brought out by a relatively large distance due to the fact that the door curtain is too soft, and consequently the swinging amplitude is relatively large when the door curtain is reset is avoided.
本发明涉及门帘技术领域，且公开了一种门帘的复位缓摆机构，包括帘体，所述帘体内腔的上端设置有储气腔，且储气腔呈倒“U”字形，所述帘体内腔的中部设置有充气槽，所述充气槽呈倒“T”字形，且充气槽上端和储气腔中部的下端连通，所述储气腔两侧的中部活动套接有活塞块。本发明通过设置复位缓摆机构，使得在门帘正常被掀开时，活塞块在向上推力的作用下，向上移动，从而使储气腔内气体不断向充气槽内挤压，从而使充气槽内压强增大，进而使门帘的下端绷直，使得在门帘自动复位时，通过绷直的门帘下端使门帘的摆动效率降低，避免了由于门帘过软，导致下端被带出较大距离，使其复位时摆动幅度较大的情况发生。
