Problems solved by technology

[0003] The current limiting structure of the refueling hose joint stabilizes the umbrella frame generally adopts the method of adding rivets to the steel wire rope. The steel wire rope passes through the hole on the adjacent bone piece. One end of the steel wire rope is fixed with a steel ball and is stuck on the hole. The other end of the steel wire rope passes through the rivet. Fixed, this limit structure has

Embodiment Construction

[0023] The present invention will be further described below in conjunction with drawings and embodiments.

[0024] A kind of space-limiting structure for stabilizing the umbrella skeleton of a refueling hose joint, comprising a rope 1 with rope loops at both ends (see figure 2 ), a bone piece 3 with a U-shaped through hole (see Figure 7 ), screw 4 and stopper 2, such as Figure 7 As shown, the U-shaped through hole is composed of a wide groove 6 and two long grooves 7 communicating with the wide groove 6 respectively, and the bone piece 3 forms a lanyard 8 between the two long grooves 7, as figure 1 As shown, two rope rings on the same rope 1 are respectively hung on the hanging rope bars 8 of two adjacent bone pieces 3, as Figure 3 to Figure 6 As shown, the stopper 2 extends into the wide groove 6 from one side of the bone piece 3 and can make the rope ring not escape from the lanyard 8, and the screw 4 is threadedly connected with the stopper 2 on the other side of the...

Abstract

The invention relates to a refueling hose joint drogue parachute framework limiting structure which comprises ropes with rope rings arranged at two ends, framework pieces with U-shaped through holes,screws and retaining blocks. Each U-shaped through hole is composed of a wide groove and two elongated grooves communicated with the wide groove, each framework piece form a rope hanging strip betweenthe corresponding two elongated grooves, the two rope rings on a same rope are respectively hung on the rope hanging strips of each adjacent two framework pieces, the retaining blocks extend into thewide grooves from one sides of the framework pieces and enable the rope rings not to go out of the rope hanging strips, the screws are in threaded connection with the retaining blocks on the other sides of the framework pieces, and the screws after being in threaded connection clamp the framework pieces to prevent the same from going out. The limiting structure is simple in structure, small in size, light in weight, convenient to mount and demount and less prone to breakage.

Description

technical field [0001] The invention belongs to the field of aerial refueling, and in particular relates to a space-limiting structure for a refueling hose joint to stabilize an umbrella frame. Background technique [0002] When the aircraft is refueling in the air, the tanker extends the refueling hose from the fuel tank. In order to ensure that the refueling aircraft and the refueling hose are accurately docked, it is necessary to set a stabilizer at the end joint of the refueling hose. The stable umbrella includes a skeleton and a canopy installed around the edge of the skeleton. The skeleton is composed of several bone pieces. The skeleton can be opened and closed by adjusting the distance between the bone pieces. The structure makes the opening angle of the framework not too large, ensuring that the refueling hose connector stabilizer umbrella maintains a certain shape, and the limit structure cannot interfere with the framework's retraction, affecting the refueling hos...
