Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

Example 1

An aircraft adapter as shown in fig. 1 to 6, comprising an adapter body 5; the adapter bodies 5 are arc petal-shaped blocks, the number of the adapter bodies is multiple, and the adapter bodies 5 can be spliced into a ring shape; the front side surface of the adapter body 5 is provided with a plurality of lightening holes.

Example 2

Based on example 1, the lightening holes are blind holes.

Example 3

Based on embodiment 1, the lightening holes are parallel to the circular arc axial lead direction of the adapter body 5.

Example 4

Based on embodiment 1, as shown in fig. 1 to 3, a cow leather pad 1 is attached to the inner arc surface of the adapter body 5; the rear side face of the adapter body 5 is an inclined face, and an included angle between the rear side face of the adapter body 5 and the inner arc face is larger than an included angle between the rear side face and the outer arc face.

Example 5

As another typical arrangement of the pelt mat 1 according to embodiment 4, as shown in fig. 4 to 6, the pelt mat 1 further covers the rear side surface of the adapter body 5.

Example 6

Based on embodiment 1, be equipped with locating pin 3 on the intrados of adapter body 5, the position cover of locating pin 3 in adapter body 5 is equipped with compression spring 2.

Example 7

Based on examples 4 and 6, the locating pin 3 penetrates the pelt mat 1.

Example 8

Based on embodiment 6, the positioning pin 3 is installed in the constraint cover 4, and the surface of the constraint cover 4 is flush with the inner arc surface of the adapter body 5.

It is easily understood that in actual use, the adapter body 5 is divided into upper and lower adapters, and embodiment 4 and embodiment 5 show the difference between the upper adapter and the lower adapter, respectively.

Example 9

Based on the above-mentioned embodiment, divide into adapter subassembly and adapter subassembly down, the adapter appearance is petaloid. The upper adapter assembly and the lower adapter assembly are composed of a leather pad 1, a compression spring 2, a positioning pin 3, a constraint cover 4, an adapter body 5 and the like. The adapter adopts petal form combined structure, and upper and lower adapter number is 6 respectively, totally 12 petal adapter constitutions. Adapter body 5 adopts the mould shaping, compression spring 2, locating pin 3, retrains the cover 4, and adapter body 5, cow hide pad 1 processing is accomplished the back and is assembled with adapter body 5, and wherein cow hide pad 1 and retrains the cover 4 and glue on adapter body 5 through sticky mode. The adapter after the assembly is installed between barrel and aircraft, and the adapter is fixed in the upper and lower terminal surface of aircraft, plays the effect of supporting the aircraft and restricting its radial motion. The adapter is different from a common adapter, the adapter body 5 of the adapter is designed with lightening holes, and the positioning pin 3 has two pin positions in different directions. After the aircraft flies out of the cylinder, the adapter body 5 is automatically separated from the aircraft and falls off under the action of the spring of the compression spring 2.

The adapter is located the upper and lower end between barrel and the aircraft, and locating pin 3 in upper and lower adapter subassembly adapter body 5 cooperates with terminal surface pinhole about the aircraft, plays support and injecing aircraft radial motion under compression spring 2 spring force condition.

Adapter body 5 design has the lightening hole in the adapter, and its lightening hole quantity is no less than 5, and the diameter is no less than 6 mm.

The number of the positioning pins 3 in the adapter is 2, and the distance between the centers of the positioning pins and the center of the adapter is 60-75 mm.

Therefore, the main working principle is as follows: when the aircraft is stored and transported, the positioning pin enables the adapter, the aircraft and the cylinder body to always keep a relative position under the action of the compression spring, and therefore the aircraft is protected. The total number of the positioning pins is 12, and the positioning is respectively performed from different directions, so that the radial positioning of the aircraft is more stable; after the aircraft flies out of the cylinder, the adapter is automatically separated from the aircraft under the action of the spring force of the compression spring.

Through verification, the light weight of the adapter meets the requirement, the aircraft is well supported, protected and limited in movement, and the adapter is reliably separated after being discharged from the cylinder, so that the movement of the aircraft is not influenced.
