The invention relates to a locking mechanism of an aircraft landing gear and the aircraft landing gear. The locking mechanism of the aircraft landing gear comprises a push-pull connecting rod, a locking device, a driving part, an upper supporting rod and a lower supporting rod. The aircraft landing gear comprises the locking mechanism, an aircraft wheel, a main body structure and an actuator. The upper supporting rod is movably connected with the lower supporting rod, the actuator drives the push-pull connecting rod and the driving component to enable the upper supporting rod and the lower supporting rod to be folded and unfolded, and then folding and unfolding of the aircraft landing gear are completed. According to the locking mechanism of the aircraft landing gear and the aircraft landing gear, linkage locking is conducted through the push-pull connecting rod, the locking device, the driving component, the upper supporting rod, the lower supporting rod and the actuator, retracting and releasing of the aircraft landing gear can be completed, an independent hydraulic device is not needed, the weight of an aircraft system is reduced, and the aircraft performance is improved; the system complexity is simplified, the use and maintenance cost of the whole system is reduced, the manufacturing cost is low, and mass production is facilitated.

    本申请涉及一种飞机起落架的锁止机构和飞机起落架,所述飞机起落架的锁止机构包括推拉连杆、锁定装置、驱动部件、上撑杆和下撑杆。所述飞机起落架包括所述锁止机构、机轮、主体结构和作动器。所述上撑杆与所述下撑杆活动连接,所述作动器驱动所述推拉连杆和所述驱动部件使所述上撑杆和所述下撑杆能够折叠和展开,继而完成飞机起落架的收和放。根据本申请提供的飞机起落架的锁止机构及飞机起落架,通过推拉连杆、锁定装置、驱动部件、上撑杆、下撑杆与作动器进行联动锁定,能够完成飞机起落架的收放,不需要单独的液压装置,降低了飞机系统重量,提升了飞机性能,简化了系统复杂度,降低了整套系统的使用维护成本,制造成本低廉,便于大批量生产。
