The invention discloses a foldable traction rod which comprises a first section of the rod, a second section of the rod and a third section of the rod, wherein a traction joint is arranged on one end of the first section of the rod; one end of the second section of the rod is articulated with the other end of the first section of the rod; one end of the third section of the rod is articulated with the other end of the second section of the rod; the first section of the rod can be obliquely bent at the articulated part relative to the direction of the second section of the rod; the third section of the rod can be obliquely bent at the articulated part relative to the direction of the second section of the rod; and when the first section of the rod is obliquely bent relative to the direction of the second section of the rod and the third section of the rod is obliquely bent relative to the direction of the second section of the rod, the projection of a connecting line of a center point of the end part of the first section of the rod, a center point of the end part of the second section of the rod and a center point of the end part of the third section of the rod in the axis direction of the first section of the rod is triangular. By adopting the mechanism, the traction joint does not mutually interfere with the middle section of the traction rod, and the volume obtained after the traction rod is folded is reduced to the maximum limit.
Description
technical field [0001] The invention relates to the field of aircraft ground technology, in particular to a foldable tow bar. Background technique [0002] When the aircraft is performing a maneuvering transfer, the support equipment generally has problems such as long preparation time before the transfer, high transportation pressure during the transfer, and slow work after the transfer, which are the bottlenecks that restrict the improvement of the aircraft's maneuverability. The "miniaturization" design of aircraft support equipment is an effective method to improve the transportation capacity of the transition. In aircraft support equipment, the tow bar is longer in size and heavier in weight, and it is extremely inconvenient to transport in sections. Adopting a foldable structure is one of the ways to realize quick retraction of the towbar, and the folding and retracting methods of the towbar are different. [0003] The principle described in the patent No. CN20141083...
