The invention belongs to the technology of lifting devices, and particularly relates to a high-reliability supporting rod lock mechanism which comprises an upper supporting rod, a lower supporting rod hinged to the upper supporting rod and a lock structure. The lock structure comprises an upper lock supporting rod, a lower lock supporting rod, a spring and an unlocking device. The upper locking supporting rod is hinged to the upper supporting rod, one end of the upper locking supporting rod is hinged to the upper supporting rod, the other end of the upper locking supporting rod is hinged to a supporting arm formed by the lower supporting rod in a protruding mode, a limiting structure is arranged between the upper locking supporting rod and the lower locking supporting rod, and the upper locking supporting rod and the lower locking supporting rod are limited by the limiting structure when unfolded to a locking position. The spring provides pretightening force for the lower lock supporting rod to move towards the upper lock position. When the upper supporting rod and the lower supporting rod are unfolded by a preset field angle, the upper locking supporting rod and the lower locking supporting rod are unfolded to a locking position, the upper locking supporting rod and the lower locking supporting rod limit continuous unfolding or folding of the upper supporting rod and the lower supporting rod, and the unlocking device provides power for the upper locking supporting rod and the lower locking supporting rod to be separated from the locking position; the supporting rod lock can bear large ground loads, a supporting rod lock mechanism is integrated, and the supporting rod lock can be mechanically locked.

    本申请属于起落装置技术,特别涉及一种高可靠性撑杆锁机构,上撑杆、与上撑杆铰接的下撑杆以及锁结构;锁结构包括:上锁撑杆、下锁撑杆、弹簧以及开锁装置;上锁撑杆铰接在上撑杆上,上锁撑杆一端铰接上撑杆另一端铰接下撑杆凸起形成的支臂上,上锁撑杆与下锁撑杆之间具有限位结构,上锁撑杆与下锁撑杆展开至上锁位置时被所述限位结构限位,弹簧提供下锁撑杆朝向所述上锁位置运动的预紧力;上撑杆与下撑杆展开预设张角时,上锁撑杆与下锁撑杆展开至上锁位置,上锁撑杆与下锁撑杆限制上撑杆与下撑杆继续展开或者折叠,开锁装置提供上锁撑杆与下锁撑杆脱出上锁位置的动力;该撑杆锁能承受比较大的地面载荷,集成有撑杆锁机构,撑杆锁能机械上锁。
