The invention discloses a retractable supporting folding wheel, which is characterized in that a foot stool locking device is fixedly mounted on a vertical pipe locking device, a rotating trundle is connected with the vertical pipe locking device through a rotating shaft, the rotating trundle can move up and down around the rotating shaft, and the foot stool locking device longitudinally locks the rotating trundle and the vertical pipe locking device through a clamping tongue. The device has the advantages of being convenient to operate, safe and reliable. When the trailer box-out trundle is in a supporting state, the foot stool locking device can completely lock the rotating trundle, so that the safety and the reliability of a trailer full-load product moving on the ground are ensured; and when the trailer box-entering trundle is in a folded state, the vertical pipe locking device can completely lock the rotating trundle, so that the safety and the reliability during continuous jolting during transportation are ensured.

    本发明公开了一种可收放的支撑折叠轮,脚架锁紧装置固定安装在立管锁紧装置上,旋转脚轮通过旋转轴与立管锁紧装置连接,且旋转脚轮可围绕旋转轴上下运动,脚架锁紧装置通过卡舌将旋转脚轮与立管锁紧装置纵向锁死。本发明的优点在于:本装置结构操作方便、安全可靠。托车出箱脚轮处于支撑状态时,脚架锁紧装置能够完全锁死旋转脚轮,保证了托车满载产品在地面运动时的安全可靠性;托车进箱脚轮处于收起状态时,立管锁紧装置能够完全锁死旋转脚轮,保证了运输持续颠簸时的安全可靠性。
