The invention discloses a freely retractable awning, and relates to the technical field of awnings, the freely retractable awning comprises a mounting rack, a winding roller is rotatably arranged on the mounting rack, a sunshade coiled material is wound on the winding roller, and a winding elastic piece used for driving the sunshade coiled material to be wound to the winding roller is arranged on the sunshade coiled material or the mounting rack or the winding roller. When the winding roller is rotated to enable the sunshade coiled material to be in an unwinding state, the winding elastic piece is in an elastic deformation state or in a weighted elastic deformation state; a self-locking assembly is arranged at the end of the winding roller, a directional locking piece is arranged on the self-locking assembly, and the self-locking assembly can be in a locking state and an unlocking state according to the rotating direction of the directional locking piece. When the directional locking piece retreats backwards, the shaft diameter of the directional locking piece tends to be shrunk, so that the clamping force acting on the winding roller becomes larger and larger, the self-locking assembly locks the winding roller, and the locking state is achieved; and the convenient function that the sunshade coiled material is freely folded and unfolded is achieved.

    本发明公开了一种收放自如的遮阳篷,涉及遮阳篷技术领域,包括有安装架,所述安装架上可转动设置有卷辊,所述卷辊上卷绕有遮阳卷材,所述遮阳卷材或安装架或卷辊上设置有用于驱动遮阳卷材卷绕至卷辊的卷绕弹性件,在转动卷辊使遮阳卷材处于放卷状态时,卷绕弹性件处于弹性形变状态,或处于加重的弹性形变状态;所述卷辊的端部设置有自锁组件,所述自锁组件上具有方向性锁紧件,所述自锁组件能够根据方向性锁紧件的转动方向,呈现有锁止状态和解锁状态;当方向性锁紧件往后退方向时,方向性锁紧件的轴径呈现缩紧的趋势,导致作用于卷辊的夹紧力越来越大,以使自锁组件抱死卷辊,实现锁止状态;实现了遮阳卷材收放自如的便捷性功能。
