The invention provides a support rotation positioning structure, which comprises a movable frame and a supporting frame rotationally installed on the movable frame through a first rotating shaft, wherein a first clamping column and a second clamping column are fixedly arranged on the supporting frame; a first clamping groove used for supporting the second clamping column from the rear side to prevent the second clamping column from moving backwards is formed in the bottom of the rear side of the supporting frame, a pedal is arranged in the movable frame, and the pedal is rotatably installed in the movable frame through a second rotating shaft. A second clamping groove used for supporting the first clamping column from the front side to prevent the first clamping column from moving forwards is formed in the upper portion of the front end of the pedal, and the rear side of the pedal is connected with the movable frame through a connecting rod assembly; wherein a torsional spring is arranged on the second rotating shaft, and the pedal is located at the limiting position of forward rotation under the action of the torsional spring. The support structure has the use state and the storage state, wherein the structure in the two states is stable and reliable and switching of the two states is convenient to operate, so that the occupied space can be reduced through storage.

    本发明提供一种支架旋转定位结构,包括活动架和通过第一转轴旋转安装于活动架上的支撑架,支撑架上固定设置有第一卡接柱和第二卡接柱,支撑架的后侧的底部设置有用于从后侧支撑第二卡接柱以阻止第二卡接柱向后运动的第一卡槽,活动架的内部设置有脚踏板,脚踏板通过第二转轴可旋转地安装于活动架内,脚踏板的前端的上部设置有用于从前侧支撑第一卡接柱以阻止第一卡接柱向前运动的第二卡接槽,脚踏板的后侧通过连杆组件连接活动架,第二转轴上设置有扭簧,脚踏板在扭簧的作用下,处于向前旋转的极限位置。本发明的支架结构具有使用状态和收纳状态,两个状态下的结构均稳定可靠,并且两个状态的转换方便操作,通过收纳能够减小占用空间。
