Abstract

The invention discloses a loader cab door locking device easy to unlock, and relates to the technical field of engineering machinery. The loader cab door locking device comprises a compression air spring. One end of the compression air spring is assembled to a cab door frame, and the other end of the compression air spring is connected with a cab door. A cylinder of the compression air spring is arranged in a locking sleeve in a sleeved manner. One end of the locking sleeve is a free end, and the other end of the locking sleeve is hinged to the stretch-out end of a piston rod of the compression air spring through a transverse hinge shaft. When the piston rod elongates to the maximum stroke position, the free end of the locking sleeve abuts against the end face of the cylinder. The locking sleeve is connected with an unlocking handle. The loader cab door locking device solves the problem that a compression air spring is used for an existing loader cab door, and locking is not reliable.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a locking device for fixing the cab door of a loader after the cab door is fully opened. Background technique [0002] At present, after the loader cab door is fully opened, the door is fixed by a positioning latch or a common compressed gas spring. Positioning latches are generally used to fix doors that can be opened at an angle of 180°. Positioning latches are composed of key parts such as a lock cylinder and a lock. The lock cylinder is generally assembled on the skeleton skin of the cab, and the lock buckle is generally protrudingly assembled on the outer surface of the door. When the door is fully opened, the lock buckle on the door is buckled into the lock cylinder to realize the locking of the door. The positioning latch can completely and effectively lock the door, and the locking function has high reliability. However, the positioning latch has high requi...
