Embodiment Construction

[0023] Below in conjunction with accompanying drawing, structure of the present invention is described in detail:

[0024] Such as figure 1 As shown, the lifting and opening linkage structure of the flip-type airliner cabin door has supports 1 and 5 distributed on both sides of the upper part of the cabin door and fixedly connected with the fuselage structure, a suspension arm 3 with two symmetrical arms, and two symmetrically arranged upper parts. Connecting rod 2, two symmetrically arranged double-arm connecting rods 7, a square connecting rod 6, two symmetrically arranged bottom connecting rods 4, an inner handle 9 hinged with the hatch structure, and connecting connecting rod 6 and inner handle 9 The connecting rod 8; wherein the two ends of the top of the suspension arm 3 are hinged with the support 1 and the support 5 respectively, and one end of the two symmetrical upper connecting rods 2 is respectively hinged with the support 1 and the support 5, and the two arms of ...

Abstract

The invention relates to the field of airliner cabin door linkage structures, and specifically relates to a lifting-opening linkage structure, which is disposed at a half-blocking turn-over airliner cabin door, and is used to control motions such as lifting and opening of the cabin door. The lifting-opening linkage structure specifically comprises: one ends of two upper connection rods are respectively connected with two pedestals; one ends of two arms of a suspension arm are respectively connected with one ends of two bottom connection rods, and the other ends of the two bottom connection rods are hinged to the cabin door; perforated fixing pieces are respectively symmetrically fixedly disposed on the two arms of the suspension arm; the middle parts of two double-arm connection rods are respectively hinged to the perforated fixing pieces, and the two arms of the suspension arm are respectively disposed at the two sides of the perforated fixing pieces; one arms of the two double-arm connection rods are respectively hinged to the other ends of the upper connection rods, and the other arms of the two double-arm connection rods are connected with a square-shaped connection rod, the other side of the square-shaped connection rod is hinged to the cabin door; and a connection rod is connected with the one end of an interior handle and the square-shaped connection rod both in a hinged way. The linkage structure has a compact main mechanism, no spouts and no multiple connection rods, and one set of 'guide groove-guide wheel' mechanism is reduced.

Description

technical field [0001] The invention relates to the linkage field of passenger aircraft cabin door mechanisms, in particular to a lifting and opening linkage mechanism installed on a semi-blocked reversible passenger aircraft cabin door for controlling the lifting and opening movement of the cabin door. Background technique [0002] At present, for the semi-blocked airliner doors that are lifted upwards and inwards and turned outwards to open, two sets of mechanisms are used to control the lifting movement and opening movement of the cabin door respectively, and a lock mechanism needs to be designed to lock the lifting mechanism after the lifting is completed. This type of design mechanism is complex in linkage, takes up a lot of space, and is heavy, especially for hatches with relatively small spaces, the design is very difficult. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the technical problem to be solved by the prese...
