Problems solved by technology

[0002] During the assembly process of the semi-blocked hatch and the fuselage, the gravity is mainly borne by the suspension system. Especially for hatches with large volume and self-weight, the course adjustment is achieved by adding or subtracting gaskets. The connection points of the system are repeatedly disassembled and assembled, which is inefficient, inaccurate, time-consuming and labor-intensive. At the same time, the adjustment of the hatch position during the maintenance process also faces many problems, including the daily storage of lifting tools and the skill requirements of maintenance personnel. large cost

Embodiment Construction

[0017] Such as Figure 1 to Figure 3 As shown, a semi-blocked cabin door course free adjustment mechanism is composed of an adjustment component and a follower component. The structure of the adjustment component is: the support I4 is a U-shaped structure, and the support I4 is provided with an adjustment transmission mechanism I. The structure of the follow-up assembly is: the support II 12 is a U-shaped structure, the support II 12 is provided with a follow-up transmission mechanism II, and two suspension arms 3 arranged in parallel are hinged side by side on the fuselage mouth frame 1, and the suspension arms 3. The other end is respectively hinged with the adjustment component and the follower component.

[0018] The support I4 in the adjustment assembly is fixedly connected to the hatch main structure 2, and the end of the suspension arm 3 is connected to the support I4 through the adjustment screw 6. The suspension arm 3 is limited between two clamping washers 11, and f...

Abstract

The present invention relates to a free course adjustment mechanism for a semi-blocked cabin door, which is composed of an adjustment assembly and a follow-up assembly. , the structure of the follow-up assembly is: the support II is a U-shaped structure, the support II is provided with a follow-up transmission mechanism II, and the course free adjustment mechanism is connected to the main structure of the hatch through the support I and the support II. The transmission mechanism I and the follow-up transmission mechanism II are connected to the suspension arm, and the other end of the suspension arm is connected to the frame of the fuselage.

Description

technical field [0001] The invention relates to an adjustment structure, in particular to an automatic adjustment structure for the course of a semi-blocked cabin door, which belongs to the field of civil aircraft cabin door mechanism design. Background technique [0002] During the assembly process of the semi-blocked hatch and the fuselage, the gravity is mainly borne by the suspension system. Especially for hatches with large volume and self-weight, the course adjustment is achieved by adding or subtracting gaskets. The connection points of the system are repeatedly disassembled and assembled, which is inefficient, inaccurate, time-consuming and labor-intensive. At the same time, the adjustment of the hatch position during the maintenance process also faces many problems, including the daily storage of lifting tools and the skill requirements of maintenance personnel. A lot of cost. Contents of the invention [0003] The technical problem to be solved by the present in...
