Refueling hose connector stable umbrella framework connecting structure

Abstract

The invention discloses a refueling hose connector stable umbrella framework connecting structure which comprises connecting lifting lugs (9), a connecting ring (6), double-end thread sleeves (7), a stable umbrella framework (1) and limiting linings (8), the connecting lifting lugs (9) are distributed on a refueling connector (4) in the circumferential direction, the connecting ring (6) is provided with an opening, threads are arranged at the two ends of the connecting ring (6), and the connecting ring (6) penetrates through the lug hole of the whole circle of connecting lifting lugs (9) in a matched mode. The double-end thread sleeves (7) are located at openings of the connecting ring (6) and sleeved at the two ends of the connecting ring (6) in a threaded fit mode, the stable umbrella frameworks (1) and the limiting linings (8) are sleeved along the line of the connecting ring (6) in a matched mode, and the limiting linings (8) are used for limiting the stable umbrella frameworks (1) at the two ends. The structure is reliable in connection, small in size and light in weight, and the connecting space of double frameworks is reserved.

Description

technical field [0001] The technical field of aerial refueling of the present invention particularly relates to a refueling hose joint stabilized umbrella skeleton connection structure. Background technique [0002] The refueling hose joint stabilizer is a non-traditional parachute, which consists of a rigid stabilizer frame and a flexible canopy. At present, such as figure 1 and figure 2 As shown, the stabilizer umbrella frame (1) is connected in the limit groove formed by the fixed ring (3) and the retainer (2) through the pin shaft (5), and the fixed ring (3) and the retainer (2) are installed on the refueling joint (4), the connection structure needs the retaining ring (2) and the fixed ring (3) to limit and stabilize the umbrella frame (1) and the pin shaft (5), resulting in heavy product weight and large volume, and it is difficult for the retaining ring (2) ) and the fixing ring (3) have high dimensional accuracy assembly requirements, and the pin shaft (5) is easy...
