Description

Technical Field

[0001] The utility model relates to the technical field of aircraft wing installation, in particular to a diagonal brace structure used for a transition bracket. Background Art

[0002] During the manufacturing and maintenance process of an aircraft, a transition bracket is needed to lift the aircraft's wings. Since the wings are installed at different angles, the angle of the wings driven by the bracket also needs to be adjusted during installation.

[0003] The existing patent document with application number 201821771166.3 provides a universal bracket for aircraft wings. The height adjustment screw of the height adjustment frame is mainly used for adjusting the height of the upper base plate, and the adjusting bolt is mainly used for adjusting different inclination angles. The utility model is suitable for supporting aircraft wings with different heights and inclination angles and has universality; although the above application has many beneficial effects, it still has the following shortcomings: when the wing is placed on the base plate, since the diagonal support part at the bottom end of the base plate is provided with a spring, the base plate of the entire bracket will tilt during the movement, which is very unstable.

[0004] Therefore, in order to solve the above problems, the utility model proposes a diagonal brace structure for a transition bracket. Summary of the invention

[0005] The purpose of the utility model is to provide a diagonal brace structure for a transition bracket to solve the problems raised in the above background technology.

[0006] The yoke is affixed to a base as claimed in claim 1, wherein the two guide rails are arranged on the upper and lower ends of the support rails and the two guide rails are rotatably connected to each other with a plurality of guide rails respectively.

[0007] Preferably, the first guide rod is slidably connected to the first hinge seat, and the linkage seat is slidably connected to the limit rod.

[0008] Preferably, a plurality of symmetrically arranged hydraulic cylinders are fixedly mounted on the top of the base, a plurality of symmetrically arranged universal wheels are provided at the bottom of the base, and the output ends of the plurality of hydraulic cylinders are fixedly connected to the bottom end of the mounting plate.

[0009] Preferably, the output end of the motor is fixedly connected to one side of the screw rod, and the screw rod is threadedly connected to the movable seat.

[0010] Preferably, the bottom end of the top rod is hinged to the second hinged seat, and the movable seat is rotatably connected to the connecting rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are: a screw rod, a movable seat, a first hinged seat, a second hinged seat and a linkage seat, etc. are provided. When the angle of the placement plate needs to be adjusted, the screw rod only needs to drive the movable seat to move, and the various mechanisms will be linked. The linkage of the various mechanisms will drive the placement plate to complete the angle adjustment action. The adjustment process is very stable, and the placement plate will not shake or suddenly tilt even during the movement of the bracket. BRIEF DESCRIPTION OF THE DRAWINGS
