Embodiment approach

[0031] When the foldable plate 1 is closed, the crescent flat 1051 terminal step on the rotating shaft 105 is directly inserted into the crescent-shaped hole 305 in the lock head 302, and then the M12 nut is used to fix the rotating shaft and rotate the rotating shaft to 90° to lock the door, and the anti-lock opening spring The sheet 303 is limited by the dead bolt 304, and the spring sheet rebounds and resets; preventing the rotating shaft from opening the door.

[0032] The invention has the advantages of simple and compact structure, strong reliability, reasonable setting, convenient and fast opening and closing of the foldable plate, good locking performance and noise reduction.

Abstract

The invention provides a locking device which comprises a foldable plate and a frame. A rotary lock buckle mechanism is arranged on the edge of the foldable plate. An elastic spring bolt mechanism is arranged at the lower end of a fixed plate perpendicular to the frame, and the rotary lock buckle mechanism comprises a rotary shaft seat and a rotary shaft arranged in the rotary shaft seat. A limiting mechanism is arranged at the upper end of the rotary shaft, and a self-locking nut is further arranged at the lower end of the rotary shaft. A lock head is fixed to a flat position milling rotary shaft through the self-locking nut. The elastic spring bolt mechanism comprises a lock seat and a lock opening preventing spring sheet arranged in the lock seat. A spring sheet of the lock opening preventing spring sheet stretches out of the lock seat to be matched with two calabash-shaped spring bolts, at the lower end of a rotary pin, on the lock head. The spring sheet is arranged between the two calabash-shaped spring bolts. The locking device is simple and compact in structure, high in reliability and reasonable in arrangement, the foldable plate can be opened and closed conveniently and fast, good locking performance is achieved, and noise can be lowered.

Description

technical field [0001] The invention relates to a locking device, in particular to a locking device for an aircraft. Background technique [0002] The lock structure of the foldable plate is widely used in aircraft. Since there is inevitably a large gap between the lock tongue and the groove entering the fixed frame structure, the connection between the lock tongue and the foldable plate is relatively loose, and the degree of freedom is relatively large. , when the aircraft starts to emit vibration noise. When used in submarines, the vibration and noise of this lock structure brings great hidden dangers to the stealth and safety of submarines; in addition, this lock structure is soaked in seawater for a long time, and some parts will also affect the use of the lock after being corroded by seawater. performance. [0003] The Chinese patent application number is 201410387231.2, which discloses a locking device with vibration damping function, including a foldable plate and a...
