The invention relates to the field of engineering machinery, and discloses a lock column, a lock body shaft sleeve, a locking structure, a lock, a bucket door, a working bucket, an aerial ladder device and a vehicle. An axial channel (2) is formed in the lock column (1), the axial channel (2) comprises a small-diameter channel section (201) and a large-diameter channel section (202) which are axially arranged, and the lock column shaft sleeve (3) is arranged in the large-diameter channel section (202); and an inner wall channel of the lock column shaft sleeve (3) and the small-diameter channel section (201) form a spring bolt moving channel (4) together. The technical problems that due to locking of a spring bolt caused by structural deformation, when a locking structure provided with the spring bolt is applied to a bucket door of a working bucket, the locking structure of the bucket door is locked and stuck due to deformation under the condition that the structure of the working bucket is slightly deformed or the manufacturing error of the bucket door is large, a push rod of the bucket door cannot be pushed by a wedge-shaped block when the working bucket is recycled, the bucket door cannot be opened, and the working bucket cannot be recycled in place are solved.

    本发明涉及工程机械领域,公开了一种锁柱、锁体轴套、锁合结构、锁、斗门、工作斗和云梯装置及车辆,该锁柱(1)内部形成有轴向通道(2),轴向通道(2)包括轴向布置的小径通道段(201)和大径通道段(202),锁柱轴套(3)设置在大径通道段(202)内,锁柱轴套(3)的内壁通道和小径通道段(201)一起形成锁舌移动通道(4)。本发明解决了由于结构变形引起锁舌卡死,致使装有该锁舌的锁合结构在应用于工作斗的斗门时,因工作斗结构轻微变形或斗门制造误差较大的情况下,斗门的锁合结构因变形而导致锁合卡死,致使工作斗回收时斗门的推杆无法被楔形块推动,出现斗门无法开启的情况,导致工作斗无法回收到位的技术问题。
