Technical Field

The invention belongs to the technical field of aviation, and particularly relates to a special tool for inspection in an aircraft cabin.

Background

According to the requirements of the aircraft overhaul process, parts in the aircraft base must be periodically repaired and inspected, so that special tools for inspecting the aircraft cabin are necessary. Because the space of the aircraft cabin is narrow and small, an inspection blind area exists, the space of human body activity is narrow and small, the extension is not opened, the inspection blind area exists by naked eyes, the narrow and long shielding part can not be assembled and inspected, all-around and all-in-place inspection can not be realized, and all inspection and repair can not be ensured. Therefore, a special tool for checking in the airplane cabin needs to be designed, and the special tool is long, thin, flexible and multi-angle, and meanwhile, the special tool cannot be too large in size and complex in structure. The invention provides a special tool, which adopts a slender rod and a spring to control the rotation angle and inspects a cabin sight blind area, a long and narrow part and a sheltering part through a flexible and changeable observation mirror.

Disclosure of Invention

In order to solve the problems, the invention provides a special tool for checking in an airplane cabin, which is used for maintaining, assembling and checking all parts in a blind area by combining a spring and a metal observation mirror in a mirror bracket by utilizing a lever principle.

The technical scheme of the invention is as follows:

a special tool for checking in an airplane cabin comprises a pull rod 1, a spring 2, a bracket 3 and a mirror bracket 6.

The pull rod 1 is of a T-shaped long rod structure, one end of the pull rod is provided with a handle, and the other end of the pull rod is provided with a pin hole.

The bracket 3 is of a sleeve structure, one end of the bracket is provided with a handle, and the other end of the bracket is obliquely connected with a fixing plate. The support 3 is sleeved outside the pull rod 1, and the inner aperture of the support 3 is larger than the outer diameter of the pull rod 1, so that the pull rod can axially move and radially swing in the support. A spring 2 is arranged between the pull rod 1 and the handle of the bracket 3.

The main body of the spectacle frame 6 is of a flat plate structure, and a convex structure is connected onto the main body; the main body and the convex structure of the mirror bracket 6 are movably connected with the fixing plate of the bracket 3 and the end part of the pull rod 1 through a pin B5 and a pin A4 respectively.

When the special tool is used, the special tool is stretched into a sight blind area in the cabin, the special tool pull rod and the support are pulled by hands, the mirror bracket rotates a certain angle along with the special tool pull rod, the condition of a required part is checked through a metal observation mirror in the mirror bracket, and the special tool is reset under the action of the spring after being loosened.

The invention has the beneficial effects that: the invention utilizes the lever principle to check each part in the sight blind area by adjusting the metal observation mirror in the special tool mirror bracket in a spatial multi-angle way; and the spring is used for resetting, so that the volume is reduced, and the smooth entering and exiting in a long and narrow area are facilitated. The invention has simple structure, exquisite design, long connecting rod type connection and convenient operation, can be pulled by hand, not only reduces the volume of the tool, but also ensures the observation of each angle of space; the problem of traditional instrument sight blind area can't accomplish and the appearance is big, be not suitable for long and narrow, little operation space etc is solved.
