Technical Field

The invention belongs to the technical field of aerial refueling, and particularly relates to a connection structure of a refueling hose joint stabilizing umbrella framework.

Background

Refuel hose nipple stabilizer is a non-traditional parachute, constitute by rigid stabilizer umbrella skeleton and flexible canopy, at present, as shown in figure 1 and figure 2, stabilizer umbrella skeleton (1) is connected at the spacing inslot that solid fixed ring (3) and protective shroud (2) formed through round pin axle (5), gu fixed ring (3) and protective shroud (2) are installed on refuel joint (4), this connection structure leads to the product weight heavy, bulky owing to need protective shroud (2) and solid fixed ring (3) spacing stabilizer umbrella skeleton (1) and round pin axle (5), and the spacing groove size precision assembly requirement that forms to protective shroud (2) and solid fixed ring (3) is higher, and round pin axle (5) drop from the spacing groove easily, follow-up double-frame connection space demand also can't be satisfied to this kind of structure.

Disclosure of Invention

The invention aims to provide a stable umbrella framework connecting structure of an oil filling hose connector, which is reliable in connection, small in size and light in weight, and a double-framework connecting space is reserved.

The technical scheme adopted by the invention is as follows:

the utility model provides an it stabilizes umbrella skeleton connection structure to refuel hose coupling, including connecting lug (9), clamping ring (6), double-end swivel nut (7), stabilize umbrella skeleton (1) and spacing bush (8), connecting lug (9) distribute on refuel joint (4) along circumference, clamping ring (6) have opening and both ends and are equipped with the screw thread, clamping ring (6) complex passes the earhole that lug (9) were connected to whole circle, double-end swivel nut (7) are located clamping ring (6) opening part and screw-thread fit's cover at clamping ring (6) both ends, stabilize the equal complex cover of umbrella skeleton (1) and spacing bush (8) and overlap at clamping ring (6) along the line, spacing bush (8) are used for spacing stabilizing umbrella skeleton (1) to both ends.

Furthermore, the lug hole is positioned at the upper part of the connecting lifting lug (9), and the lower part of the connecting lifting lug (9) is connected with the oil filling joint (4) through a threaded hole.

Further, the threads at the two ends of the connecting ring (6) are opposite to each other.

Furthermore, the connecting ring (6) is made of high-strength steel.

Furthermore, the limiting bush (8) is axially matched with the radian of the connecting ring (6).

The invention has the beneficial effects that:

the connecting ring (6) is provided with an opening, so that the stable umbrella framework (1), the double-head thread sleeve (7), the limiting bush (8) and the connecting lifting lug (9) can be conveniently inserted, the integral connecting ring (6) can effectively provide the connection of the stable umbrella framework (1), and a connecting space with double frameworks is reserved; the limiting bush (8) can ensure the position stability of the stabilizing umbrella framework (1), replaces the structures of the retainer ring (2) and the fixing ring (3), and reduces the volume and the weight of the structure; the connecting lifting lug (9) has the advantages of small volume, light weight and the like relative to the retainer ring (2) and the fixing ring (3).
