The invention provides an undercarriage down lock. The undercarriage down lock comprises a lock shell, a lock arm, an actuating cylinder axially acting on the lock shell and a guide pin roller arranged in the lock shell, and the lock arm can move into the lock shell in the lateral direction. The lock arm laterally moves into the lock shell to form a first position and a second position, and when the lock arm is in the first position, the front end face of the lock arm is in sliding contact with the guide pin roller; and when the lock arm is at the second position, the actuating cylinder extends out and is locked with the lock arm and the lock shell. Compared with the prior art, the undercarriage down lock provided by the invention can correct the deviation of the track, so that the undercarriage can be smoothly locked under the condition of deviating from the original track, and the situation that the structure is excessively reinforced due to the rigidity requirement is avoided.

    本发明提供一种起落架下位锁。所述起落架下位锁包括锁壳、锁臂、以及轴向作用于所述锁壳上的作动筒、在所述锁壳内设置的导向滚柱,所述锁臂能沿侧向位移至所述锁壳内;所述锁臂沿侧向位移至所述锁壳内形成有第一位置和第二位置,所述锁臂在第一位置时,其前端面与所述导向滚柱滑动接触;所述锁臂在第二位置时,所述作动筒伸出并与所述锁臂和锁壳锁紧。与相关技术相比,本发明提供的起落架下位锁能够纠正轨迹的偏移,使起落架在偏离原来的轨迹情况下,也能顺利上锁,从而避免由于刚度需要对结构的过分加强。
