Problems solved by technology

At present, for the transmission between the vertical axes, the cabin door of civil aircraft generally adopts a space four-bar mechanism, but the space four-bar mechanism has certain restrictions on the transmission angle of the two transmission shafts, and requires a certain distance between the two transmission shafts. The distance between the two vertical shafts in the same plane cannot be realized, which greatly limits the layout and design of the hatch mechanism

Embodiment Construction

[0021] like figure 1 and figure 2 As shown, a transmission mechanism for the outer handle of the cabin door includes a lock shaft 1, a hatch beam structure 10 and an outer handle 14. The outer handle 14 is connected to the outer handle shaft 13, and the axis of the outer handle shaft 13 is connected to the axis of the lock shaft 1. Arranged vertically; the upper end of the outer handle shaft 13 is connected to the lower crank 15, and one end of the lower crank 15 is the outer handle shaft 13 as a rotating shaft, and the other end of the lower crank 15 is connected to a linkage rod mechanism, and the linkage rod mechanism passes through the door beam structure 10. The elongated groove 11 is connected with the upper crank 2 provided on the lock shaft 1 behind.

[0022] like image 3 As shown, the specific structure of the linkage mechanism is as follows: on the connecting rod 6, the lower crank roller 9, the upper limit roller 7 and the upper crank roller 4 are sequentially c...

Abstract

The invention relates to a transmission mechanism of a cabin door outer handle. The transmission mechanism comprises a lock shaft, a cabin door beam structure and the outer handle. The transmission mechanism is characterized in that the outer handle is connected with an outer handle shaft, and the axis of the outer handle shaft is perpendicular to the axis of the lock shaft; the upper end of the outer handle shaft is connected with a lower crank, the handle shaft serves as the rotation axis for one end of the lower crank, the other end of the lower crank is connected with a linkage rod mechanism, and after penetrating through a long-strip-shaped groove formed in the cabin door beam structure, the linkage rod mechanism is connected with an upper crank arranged on the lock shaft. The transmission mechanism is good in controllabitity, the cabin door structure layout is not influenced, and meanwhile it is guaranteed that the handle opening process is simple and is not limited.

Description

technical field [0001] The invention relates to a transmission mechanism for an outer handle of a cabin door, which is applied to a cabin door of a civil aircraft to realize the rotation of the outer handle of the cabin door from inside to outside. Background technique [0002] At present, for civil aircraft cabin doors, the outer handle is mostly in the form of turning up and down or left and right. For the scheme of turning up and down, due to the influence of the configuration of the outer handle, it is often necessary to break or weaken the beam structure of the hatch, and the beam structure is the main load-bearing structure of the hatch, and its performance has an important impact on the overall load-bearing capacity of the hatch. For the cargo door and other types of doors located at the tail of the fuselage, the handle position is higher than that of the person who opens the door. The process of opening the handle is not conducive to the force of the door opener, and...
