The invention discloses a locking structure and a quick folding type double-layer cart, and aims to solve the problems that a locking structure in an existing cart is complicated to operate, the efficiency is low when the cart is folded or unfolded, and the locking function of the locking structure is not stable enough. The locking structure comprises a base used for being connected with a loading panel in the double-layer cart; a barrier plate which is provided with a limiting part and a connecting part which are opposite in position, the limiting part is used for limiting sliding of a shear fork arm in the double-layer cart, and the connecting part is rotationally connected with the base; and an elastic piece which is connected between the limiting part and the base and is used for providing an elastic trend for enabling the limiting part to be far away from the base. When the locking structure is applied to the quick folding type double-layer cart, the stability of the cart during unfolding can be improved, and the operation is simple and convenient during unfolding and folding.

    本发明公开了一种锁止结构及快速折叠式双层推车,以解决现有的推车中锁止结构操作较为繁琐,推车在折叠或展开时效率不高,且锁止结构的锁止功能不够稳定的问题。其中,锁止结构包括:底座,用于与双层推车中的载物面板连接;阻挡板,阻挡板具有位置相对的限位部和连接部,限位部用于对双层推车中的剪叉臂的滑动形成限位,连接部与底座可旋转连接;弹性件,连接于限位部与底座之间,用于提供使限位部远离底座的弹性趋势。该锁止结构运用于快速折叠式双层推车中时能够提高推车展开时的稳定性、且展开折叠时操作简便。
