Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical engineering, and in particular relates to a locking mechanism for an aircraft landing gear. Background Art

[0002] The landing gear is an accessory device at the bottom of an aircraft that supports the aircraft during takeoff, landing or taxiing on the ground (or water surface) and is used for movement on the ground (or water surface). The landing gear is the only component that supports the entire aircraft, so it is an integral part of the aircraft.

[0003] The aircraft landing gear needs to be inspected and maintained after use. The existing inspection and maintenance methods are mostly to support and lift the aircraft by using an aircraft jack. Since the aircraft jack is large in size and weight, it not only occupies a large space but is also inconvenient to move and use. Therefore, an aircraft landing gear locking mechanism is proposed to support the aircraft instead of the aircraft jack. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing aircraft jack is large in size and weight, which not only occupies a large space but also is inconvenient to move and use.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a locking mechanism for an aircraft landing gear, comprising a base, connecting ears are arranged on both sides of the base, guide sleeves are arranged at the connecting ears, a lifting screw is inserted into the inside of the guide sleeve, an adjusting nut is rotatably connected in the middle of the guide sleeve, and a support seat is commonly inserted into the top of the lifting screws on both sides, and the base and the support seat are composed of two semicircular arc plates, one side of the arc plate is bolted by a hexagonal slotted nut, and the other side is provided with a locking screw.

[0006] As an improvement, the base is provided with a support leg extending horizontally to the ground on one side of the unlocking screw.

[0007] As an improvement, the inner side of the adjusting nut is connected to the lifting screw rod through threads.

[0008] As an improvement, a rubber gasket is provided on the inner side of the support seat.

[0009] As an improvement, the two semicircular arc plates are rotatably connected at the hexagonal slotted nut bolt connection.

[0010] As an improvement, the base and the support seat are provided with corresponding fixed slots at the locking screw, and the locking screw is an overall T-shaped structure, with the two ends of the top of the T-shaped structure rotatably connected to the fixed slot on one side, and the remaining side is threadedly connected with a fixing nut.

[0011] The advantages of the utility model compared with the prior art are:

[0012] The aircraft landing gear locking mechanism can adjust the height of the lifting screw by screwing the adjusting nut, so that the height of the device can be raised, thereby replacing the aircraft jack for use, and can support the aircraft by wrapping the outside of the aircraft landing gear with two semicircular arc plates to prevent the aircraft from falling. It has a small size, light weight, strong practicality, and saves airport space. BRIEF DESCRIPTION OF THE DRAWINGS
