Problems solved by technology
[0002] The conventional external storage of the aircraft is generally a revolving body. When the hook is connected to the external storage, the stop arm of the suspension hook installed obliquely has a better bonding surface with the external storage, such as figure 1 As shown (revolving body 1, stop arm 2, hook 3); however, when the hook is connected to a non-revolving surface with a large radius of curvature, the stop arm of the hook and the connecting surface cannot be well matched. Can't reach stop effect

Embodiment Construction
[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0015] see Figure 2 ~ Figure 3 A spring hook stop transition structure, including a large radius of curvature stop contact surface 4, a transition structure 5, a spring hook stop arm 6, a spring hook 7, an embossed or rubber pad contact surface 8, and a wedge-shaped top block 9. Transition structure base 10 and fixing bolts 11; due to the large radius of curvature of the contact surface between the hanging object and the stop arm 6 of the hanging hook, the stopping arm 6 of the hanging hook cannot tighten the hanging carrier of the hanging object, so the hanging carrier on the hanging hook 7 A transition structure 5 is added between the stop contact surface 4 with a large curvature radius, and the wedge-shaped top block 9 set on the transition ...

A stop transition structure of a bomb shackle comprises a stop transition assembly symmetrically arranged between the bomb shackle and a large-curvature-radius stop contact face. The stop transition assembly comprises a simulation contact face, wedge-shaped ejection blocks and a transition structure base. The wedge-shaped ejection blocks are fixed to the transition structure base having the same appearance with the large-curvature-radius stop contact face. The simulation contact face is arranged on the face, making contact with the large-curvature-radius stop contact face, of the transition structure base so that the friction force between the transition structure and the large-curvature-radius stop contact face can be simulated and the stop function can be ensured. The wedge-shaped ejection blocks are connected with bomb shackle stop arms. The bomb shackle stop arms are connected with the bomb shackle. Due to the adoption of a shape preserving design method, tight attachment of the transition structure and the large-curvature-radius stop contact face is ensured; by adjusting the inclination angle of the bomb shackle stop arms, designing the wedge-shaped ejection blocks and connecting the wedge-shaped ejection blocks to the bomb shackle, the connection capacity of the bomb shackle is effectively expanded, the bomb shackle can have the self-adaption capacity, and therefore the requirement for the appearance of a hung object is lowered.
Description
technical field [0001] The invention relates to the technical field of aircraft structures, in particular to a stop transition structure for a hanger. Background technique [0002] The conventional external storage of the aircraft is generally a revolving body. When the hook is connected to the external storage, the stop arm of the hanging hook installed obliquely has a better bonding surface with the external storage, such as figure 1 As shown (revolving body 1, stop arm 2, hook 3); however, when the hook is connected to a non-revolving surface with a large radius of curvature, the stop arm of the hook and the connecting surface cannot be well matched. The stopping effect cannot be achieved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a snap hook stop transition structure to solve the above-mentioned shortcomings in the background technology. [0004] The technical problem solved by the present invention a...
