A locking device with damping function

Abstract

The invention discloses a locking device with a vibration reducing function. The locking device comprises a foldable plate and a fixed frame, wherein a rotating latch mechanism is arranged at the edge of the foldable plate; an elastic spring bolt mechanism is arranged at the lower end of an extension lug plate of the fixed frame; the rotating latch mechanism comprises a rotating pin base, and rotating pins arranged in the rotating pin base; a spanner buckle is arranged at the upper end of the rotating pin, a limiting mechanism is arranged at the middle end, and a latch is arranged at one side of the lower end; through holes are formed in the edges of the foldable plate and the extension lug plate of the fixed frame corresponding to the rotating pins; and the rotating pins are matched with spring bolts of the elastic spring bolt mechanism after penetrating in the through holes. The locking device has the advantages of simple and compact structure, strong reliability and reasonable setting, can conveniently and quickly open or lock the foldable plate, has excellent vibration reducing performance, and can reduce the noise to a great extent.

Description

technical field [0001] The invention relates to a locking device with vibration damping function. Background technique [0002] The foldable plate is generally arranged on the outer surface of the shell and requires smoothness, and the internal space is narrow, and it is installed with pipes, cables, instruments, connectors, etc., which requires frequent attention by personnel. The performance of the foldable plate lock affects the performance of the foldable plate. use. Wherein, the foldable plate lock is an outward opening type, and there are many such foldable plates arranged on the upper deck of the upper interlayer of the pressure hull of a submarine. The original foldable plate lock structure generally designs a groove on the fixed frame structure supporting the foldable plate. The position, shape, and size of the opening of the groove should correspond to the lock tongue installed on the foldable plate. The purpose of locking the foldable plate is achieved by pushin...

AI Technical Summary

Problems solved by technology

[0003] The lock structure of the foldable plate is widely used in aircraft, but because 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 small. Large, when the aircraft starts to vibrate and make 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
