Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical engineering, and particularly relates to a foldable anti-rat device for an aircraft landing gear. Background Art

[0002] When an aircraft is parked and stored, a rat guard is one of the necessary protective tools. In areas with severe rat infestations, rats can cause damage to the aircraft landing gear, and even enter the fuselage along the landing gear, damaging the internal cables and on-board equipment of the fuselage, posing a serious flight safety hazard.

[0003] Currently, military and civilian aircraft often use metal rat guards, or directly splice several rectangular plates into a barrel shape for protection to prevent rats from climbing, but this method cannot protect the area above the top, and there is still a possibility that rats may enter. In addition, most of the existing rat guards and rat guard plates are fixed structures, which are not convenient for storage when not in use. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing rat guard or rat guard plate cannot protect the area above the top, and there is still a possibility that rats may enter. Moreover, since most of the rat guards and rat guard plates are fixed structures, they are not convenient for storage when not in use.

[0005] To solve the above technical problems, the technical solution provided by the utility model is: a foldable anti-rat device for an aircraft landing gear, including a plurality of side wall plates vertically arranged with respect to the ground. The sides of the plurality of side wall plates are rotatably connected by a plurality of first damping hinges, and the plurality of side wall plates enclose a rectangular structure of a fence. The upper end surface of the side wall plate is rotatably connected with a rat guard through a plurality of second damping hinges. Above the inner side of one side wall plate, an L-shaped rotary limit seat is rotatably connected. Inside the L-shaped structure of the rotary limit seat, an outer rod and an inner rod are symmetrically arranged. On both sides perpendicular to the rotary limit seat at the bottom of the side wall plate, limit plates are provided.

[0006] Preferably, the outside of the corner where the fence is connected to one side wall plate is fixedly connected by a plurality of 90-degree locks.

[0007] Preferably, the sides of the fence are connected to two side wall plates in a planar manner through a plurality of connecting locks.

[0008] Preferably, a handle is provided above the outside of the side wall plate, and a note label is provided below the handle on the outside of the side wall plate.

[0009] Preferably, the rotation angle of the multiple second damping hinges between the rat-proof cover and the side wall plate is 0 to 180 degrees, and the rat-proof cover is provided with a 45-degree chamfer at the bending part of the rectangular structure composed of the multiple side wall plates.

[0010] Preferably, the outer rod is located at both ends of the rotation limit seat, the inner rod is located inside the outer rod, and the inner rod and the outer rod are on the same straight line. Both the inner rod and the outer rod are fixedly connected to the rotation fixing seat through threads, and the outer rod is a tensile structure.

[0011] Preferably, a wheel stopper is arranged above the two limit plates, and the wheel stopper is a triangular block structure.

[0012] The advantages of the present utility model compared with the prior art are as follows:

[0013] This rat-proof device can be folded and stored by means of a combination of multiple damping hinges. It can be unfolded during use, which is convenient for use. Moreover, the opening and closing angle is limited by a 90-degree lock or multiple connection locks, thereby preventing deformation during use. At the same time, a rotatable rat-proof cover is arranged above the side protection plate, so that the protection angle above can be dynamically adjusted, thereby increasing the protection above the side protection plate.
