The 1# copper bush is installed on the missile hanger front support lug butt joint round hole, and the 2# copper bush is installed on the missile hanger rear support lug butt joint slotted hole, prevents the support hole wearing and tearing destruction.

The working principle of the utility model is as follows:

the method comprises the steps that 1# copper bush is pressed into lifting lug butt-joint round holes in the two sides of a right front support and a left front support, 2# copper bush is pressed into lifting lug butt-joint round holes in the two sides of a right rear support and the left rear support, according to the hanging point position of an unmanned aerial vehicle, four front and rear support mounting positions are determined, each support is fixed on a main force bearing frame of a machine body through 4M 6 bolts, gaskets, slotted nuts and split pins, lifting lugs on the two sides of each support are used for mounting a missile hanger, the fork lug butt-joint holes of the missile hanger are aligned with the lifting lug butt-joint holes in the front and the rear of the. During the flight of the airplane, the four front and rear supports ensure the balance of the hanging rack under various complex load conditions and provide restraint to prevent the left and right swinging.

The utility model has the advantages that:

(1) the missile hanging rack connecting support has the advantages of simple structure, light weight and low cost.

(2) The missile hanger connecting support structure and the missile hanger are convenient to mount and dismount, and the joint is good in visibility and convenient to inspect.

(3) The missile hanger is connected with the bottom of the support and attached to the aerodynamic appearance of an airplane, the connection between the missile hanger and the airplane body is simple and reliable, and the support lifting lugs are rounded to reduce wind resistance.

(4) In the missile hanger connecting support structure, a round hole is formed in a butt joint hole of a front support lifting lug, a long round hole is formed in a butt joint hole of a rear support lifting lug, and the longitudinal sizes of the missile hanger and front and rear mounting supports of a machine body are convenient to adjust and calibrate during assembly, so that the assembly error is favorably adjusted;

(5) the missile hanger connecting support structure is provided with the bilateral lifting lugs which are longitudinally connected with the fixed hangers, so that the missile hanger and the missile can be safely and fixedly locked on the airplane body, the missile is prevented from swinging in various flying carrying states, particularly in pitching, yawing, rolling, sideslipping and climbing processes, and the safety stability, the operation performance and the flight performance of the airplane are improved.

(6) All parts in the missile hanger connecting support structure can be detached, and when the airplane is used for a long time and the parts are worn or damaged, the installation interchangeability is realized, the disassembly, the assembly and the adjustment are convenient, and the fault parts are replaced.

The missile hanging rack connecting support structure is light in weight, high in strength, good in rigidity, simple in structure, convenient to assemble and disassemble and good in maintainability.
