A hatch that slides open

Abstract

The invention relates to a sliding opening mechanism for a cabin door. A handle lock assembly is connected to the lower end of the handle mechanism through a spline, a guide post is fixedly connected to one side of the handle mechanism, and symmetrically arranged handle lock assemblies are fixedly connected to the top and bottom of the cabin door. The lock assembly is connected through transmission part I, and the handle lock assembly corresponding to the upper and lower sides of the cabin door is connected through transmission part II. The lower end of the handle lock assembly is connected with a roller assembly, which slides in the slide rail. The slide rail is L-shaped, and the guide column is along the slide rail. The vertical part of the chute performs sliding movement, and the end of the slide rail is provided with a hatch door opening locking mechanism and a limit stopper, and the slide rail is fixedly connected with the hatch door frame. First slide vertically, then slide horizontally to open the hatch. A handle mechanism is provided inside the hatch, and the handle mechanism controls the opening and closing of the hatch through a linkage opening component, which solves the complicated and safe hatch mechanism existing in the prior art. Technical solution with low performance.

Description

technical field [0001] The invention relates to a cabin door, in particular to a sliding opening mechanism for the cabin door, which belongs to the field of aircraft cabin door manufacturing. Background technique [0002] According to the opening form, the hatch can be divided into a rotary opening hatch and a translation opening hatch. [0003] Rotate to open the door When the door is rotated and opened, the door structure is inside the fuselage during the opening process, occupying the door space; when it is rotated directly to the outside of the cabin, the reliability and safety are not high, and the movement is first inward and then outward When the door is rotated to open, the door mechanism is complicated; when the door is opened by translation, the door is directly translated, which is not reliable and safe. When the door is moved inward and then opened by translation, the door mechanism is complicated. Contents of the invention [0004] The technical problem to be...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a hatch door that slides open, first slides vertically, and then slides horizontally to open the hatch door. A handle mechanism is provided inside the hatch door, and the handle mechanism controls the opening of the hatch door through a linkage opening assembly. Opening and closing, which solves the technical solution of complex hatch mechanism and low safety performance in the prior art
