Description

Technical fields:

[0001] This utility model relates to the technical field of wing connection structures, and more specifically to a wing that is easy to connect. Background technology:

[0002] Light sport aircraft are small aircraft designed for non-commercial purposes such as flight training, private recreation, and aviation sports. Currently, the fuselage and wings of light sport aircraft are generally constructed from a frame and an outer skin. The frame or skin is typically made of carbon fiber or fiberglass, while the fuselage and wings are manufactured separately. The wings are then assembled onto the fuselage. Currently, some aircraft connect the fuselage and wings primarily through a beam-slot splicing method. The wings have multiple connecting beams extending from the wing, which are inserted into slots within the fuselage. The connecting beams and slots are then connected by pins. This requires the pins to be fixedly connected to the slots, which is cumbersome. Therefore, a structure that facilitates pin positioning is needed to simplify wing installation and connection. Utility model content:

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a conveniently connected wing. The wing has an inspection port at the connection between the fuselage and the wing, through which locking pins can be easily inserted. At the same time, an interlocking mechanism is set between the locking pins to facilitate the installation and positioning of the locking pins; thus, it facilitates the installation and connection of the wing.

A locking block is provided directly below the middle of the C-shaped channel steel, with a vertical locking bolt inserted into the middle of the locking block. The upper end of the locking bolt passes through the C-shaped channel steel and is screwed with a nut, which is welded and fixed to the upper end face of the C-shaped channel steel. Slanted connecting rods are hinged to the front and rear sides of the locking block via pins. The ends of the connecting rods are inserted between the telescopic arms and connected to a hinge shaft, with both ends of the hinge shaft respectively inserted and fixed to the telescopic arms.

A locking block 67 is installed inside the C-shaped channel steel 61; a locking block 67 is provided directly below the middle of the C-shaped channel steel 61, and a vertical locking bolt 68 is inserted into the middle of the locking block 67. The upper end of the locking bolt 68 passes through the C-shaped channel steel 61 and is screwed with a nut. The nut is welded and fixed to the upper end surface of the C-shaped channel steel 61. The front and rear sides of the locking block 67 are respectively hinged to oblique connecting rods 65 by pins. The end of the connecting rod 65 is inserted between the telescopic arms 64 and is connected to a hinge shaft 66. The two ends of the hinge shaft 66 are respectively inserted and fixed to the telescopic arms 64.

[0023] The outer edge of the side wing 2 near the wing root 11 is inserted into the wing root 11 and fixed together with the wing root 11 by glue.

[0024] The inner wall of the connecting sleeve 12 and the outer wall of the connecting beam 21 are in the same rectangular column.

[0025] The length of the inspection and installation port 14 is greater than the length of the locking pin 3.
