Embodiment approach

[0037] When the foldable plate 1 is closed, the crescent-shaped hole 3021 provided on the lock tongue A302 matches the crescent offset 1051, and the rotating shaft is rotated 105 to 90° to lock the foldable plate 1, and the lock tongue B engages with the lock tongue A at the same time , the deadbolt B is stuck; prevent the rotating shaft 105 from opening the revolving door.

[0038] The invention has the advantages of simple and compact structure, strong reliability, reasonable arrangement, convenient and fast opening and closing of the foldable plate, good locking performance and noise reduction.

Abstract

The invention provides a locking device with function of preventing mistaken unlocking caused in shaking. The locking device comprises a folding plate and a frame. A rotary lock catch mechanism is arranged on the edge of the folding plate. An elastic lock tongue mechanism is arranged at the lower end of a fixed plate perpendicular to a frame. The rotary lock catch mechanism comprises a rotating shaft seat and a rotating shaft arranged in the rotating shaft seat. A spacing mechanism is arranged at the upper end of the rotating shaft. A self-locking nut is arranged at the lower end of the rotating shaft, and fixes a lock on the rotating shaft at a milling flat position. The elastic lock tongue mechanism comprises a lock bracket and an anti-unlocking spring plate mounted in the lock bracket. The anti-unlocking spring plate extends out of the lock bracket and is matched with two gourd-shaped lock tongues on the lock arranged at the lower end of a rotating pin. The spring plate is arranged between the two gourd-shaped lock tongues. The locking device is simple and compact in structure, high in reliability, and reasonable in arrangement, and has high locking performance, the folding plate can be conveniently and quickly folded and unfolded, and the noise can be reduced.

Description

technical field [0001] The invention relates to a locking device. 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 fixed frame, which is characterized in that a rota...
