Abstract

The invention discloses a rapid-connection type traction rod. A horizontally-placed base plate (5) is arranged at one end of a traction rod body (1), and an airplane traction joint (2) is arranged on the base plate (5); an airplane wheel (4) is arranged below the traction rod body (1); the airplane traction joint (2) comprises a first single-plate pull rod (201a), a second single-plate pull rod (201b) and a double-plate clamp (202), wherein the clamping end of the double-plate clamp (202) is in a circular-arc shape; a tractor connecting end (3) comprises a connecting part body, and the connecting part body is provided with a U-shaped groove (301); and a locking tongue (302) is arranged in the U-shaped groove (301), and an unlocking plate is arranged on the side surface of the U-shaped groove (301). A nose-gear is automatically locked, and connection between the traction rod and the nose-gear is achieved; and the nose-gear and a tractor traction part are rapidly connected, use is convenient, and the use process is safe.

Description

technical field [0001] The invention relates to a drawbar, in particular to a quick-connect drawbar which is convenient to use. Background technique [0002] The aircraft tow bar is a device connected between the tractor and the nose landing gear of the aircraft when the aircraft is pushed and towed. In the prior art, the connection between the tow bar and the aircraft landing gear is generally connected by screws, and the screws need to be locked during the connection process. The connection is inconvenient, and at the same time, during the process of pushing and towing the aircraft, the screws may become loose, posing a safety hazard. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art and provides a quick-connection drawbar with convenient and safe connection. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A quick-connect type to...
