Rotary button lock

Abstract

The invention discloses a rotary button lock. The rotary button lock comprises a lock bracket, a driving piece, a swing arm, a sliding block, a support and a pressing head, wherein the driving piece,the swing arm, the sliding block, the support and the pressing head are arranged on the lock bracket, a driving insertion hole is formed in one side of the lock bracket, a sliding groove is formed inthe other side of the lock bracket, the driving piece is sleeved with the driving insertion hole, the sliding block is installed in the sliding groove, one end of the swing arm is connected with the driving piece, the other one end of the swing arm is connected with one end of the sliding block, the support is in a bent shape, one end of the support is hinged to the lock bracket, guide grooves areformed in the middle of the support, the other end of the support is connected with the pressing head, a shifting pin is arranged at the other end of the sliding block, the end part of the shifting pin extends into the guide groove, the driving piece comprises a shaft shell and an ejector rod, the shaft shell is sleeved with the driving insertion hole, a through groove is formed in the shaft shell, and a limiting clamping block is arranged on the ejector rod. The rotary button lock is simple in structure, small in size, light in weight, convenient to install and rapid and reliable in unlocking and locking operation, no protruding structure exists on the surface of a covering cap after installation, and the better aerodynamic configuration of an aircraft is guaranteed.

Description

technical field [0001] The invention relates to a rotary button lock, which belongs to the technical field of aircraft flap locks. Background technique [0002] In order to ensure that the airborne equipment on the aircraft is maintained and repaired in a timely manner, the surface of the aircraft needs to be provided with a large number of covers. The covers are divided into quick-release covers and non-quick-release covers according to their characteristics. The lid generally only needs to be simply pressed, twisted, or the entire flap can be opened or closed with a simple tool. [0003] At present, the fast opening and closing of various types of flaps used on aircraft can be mainly divided into several types such as rotary type, screw type, snap button type, hook tongue type, and integral detachable type in terms of mechanism principle and operation mode. Rotary quick-release locks are easy to use and small in size, but relatively weak in load bearing capacity; snap-on ...

AI Technical Summary

Problems solved by technology

The rotary quick release lock is easy to use and small in size, but its load bearing capacity is relatively weak; the snap button quick release lock can withstand large loads, but the operating space and opening size are large; the hook tongue quick release lock has good sealing performance And larger load-bearing capacity, but only suitable for larger wall thickness

[0004] At present, the connecting locks used in aerospace operation covers have the disadvantages of large size, heavy weight, unchanged operation, openings for both the hole cover and the opening frame, and the inability to seal against rain, and it is extremely inconvenient to lock and open. Meet the requirements of increasingly high-speed military products
