A connecting rod throwing device

Abstract

The invention belongs to the technical field of helicopter structure design, and discloses a connecting rod release device, which is used to solve the problem that when the rotation plane of the handle shaft of the release handle is not on the same plane as the motion track of the hinge rod, the operation force of the release mechanism is large and the cabin The door is thrown and stuck. Solve the linkage problem between the throwing mechanism and the hatch locking mechanism, operate the throwing mechanism to drive the locking mechanism to unlock, completely separate the hatch from the hatch frame, and provide emergency exits.

Description

technical field [0001] The invention belongs to the technical field of helicopter structure design, and in particular relates to a connecting rod throwing device. Background technique [0002] Existing helicopter door release mechanism can be divided into two types: explosive type and mechanical type. Because the explosive type release mechanism needs to do a lot of tests to verify the explosion equivalent, direction, explosion effect, etc., and operate the release handle in an emergency During this time, personnel are close to the explosion point, and there are certain potential safety hazards. Therefore, except for a few military aircraft that use explosive release mechanisms, the release mechanisms of most helicopter hatches are mechanical release mechanisms. [0003] The principle of most mechanical throwing mechanisms is that by turning the throwing handle, the hinge strip connected between the door and the door frame moves downward until the door hinge is disengaged, a...

Problems solved by technology

However, in the design process of the hatch of some models, due to the limitation of the outer surface of the hatch or the space of the hatch, the rotation plane of the throwing handle cannot be on the same plane as the motion trajectory of the hinge cleaner. At this time, the straight line of the cleaner There is a problem of uncoordinated movement between the movement and the rotation of the throwing handle, which will cause excessive throwing operation force and throwing stagnation

[0004] Most of the mechanical throwing mechanisms are not linked with the door locking mechanism. Operating the throwing handle only removes the hinge shaft, and the door is still connected to the door frame through the locking mechanism. After the hinge shaft is taken off, the door itself Still stuck on the frame of the door frame, the risk of not being able to provide an exit in an emergency
