Detailed Description
The present invention will be described in further detail below by way of specific embodiments:
referring to fig. 1, an automatic connection type quick release coupling comprises a support assembly 2, an upper coupling 3, a top seal ring 4, a bottom seal ring 5 and a lower coupling 6; the top sealing ring 4 and the bottom sealing ring 5 are respectively arranged in a sealing ring groove of the upper joint 3, the upper joint 3 is fixedly arranged on the ejection seat, and the lower joint 6 is arranged on the ejection cylinder support arm 1 through the support component 2.
When the seat is hung into the cabin, the 60-degree chamfer angle at the nozzle of the upper joint 3 and the lower joint 6 is contacted, the lower joint 6 is provided with lateral guiding force along with the downward placement of the seat, and the lower joint 6 moves horizontally along the radial direction in the support assembly 2, so that the automatic butt joint of the upper joint 3 and the lower joint 6 is realized.
Referring to fig. 2, the seat assembly 2 includes a seat 7, a cover plate 8 and a fastener 9; the longitudinal section of the support 7 is of an L-shaped structure, 2 semicircular holes with the same diameter are arranged on one side below the support, mounting holes are distributed around the 2 semicircular holes, 2 square holes are arranged on one side above the support, and mounting holes are distributed above the square holes; the cover plate 8 is of a cuboid structure, wherein one side of the cover plate is provided with 2 semicircular holes with the same diameter, and the other side of the cover plate is distributed with mounting holes corresponding to the mounting holes distributed around the 2 semicircular holes on the support 7; one side of the support 7 with the semicircular hole is attached to one side of the cover plate 8 with the semicircular hole and then fixed by a fastening piece 9. The lower joint 6 can flexibly move on the support assembly 2, so that the space is saved, and the weight is reduced.
Referring to fig. 3, the lower joint 6 is an L-shaped joint, two ends of the joint are respectively provided with a chamfer of 60 degrees, one longer end of the joint is provided with an annular groove, and the annular groove of the lower joint 6 is arranged in semicircular holes of the support 7 and the cover plate 8 and is fixedly arranged on the support component 2.
The two lower joints 6 have different lengths at the longer ends. The distance between the semicircular holes of the support 7 and the cover plate 8 can be minimized, the space is saved, and the weight is reduced.
The ring channel of lower clutch 6 is installed in the semicircle orifice of support 7 and apron 8 of support subassembly 2, and the ring channel diameter of lower clutch 6 is less than the semicircle orifice diameter of support 7 and apron 8, and the height that highly is greater than support 7 and the semicircle orifice height of apron 8 of ring channel guarantees that lower clutch 6 has certain clearance in support subassembly 2, can float along axial and radial on support subassembly 2.
When the seat is transferred, the bottom sealing ring 5 is in contact with the chamfer angle of the lower joint 6, and the sealing principle of the sealing ring is that the sealing ring is extruded by an inner cavity of the lower joint 6, so that the sealing ring is elastically deformed, and contact pressure is generated on a sealing contact surface, thereby realizing sealing. Therefore, in order to avoid the failure of the bottom sealing ring 5 caused by the chamfer matching problem with the lower joint 6 in the lowering process, the top sealing ring 4 is added. Therefore, the upper joint 3 adopts a double-sealing ring structure, the bottom sealing ring 5 plays a role in protection, the seat is prevented from being quickly hung into the cabin to influence the sealing performance, and the top sealing ring 4 plays a main sealing role.
When the ejection seat starts ejection, the generated fuel gas is transmitted through the fuel gas transmission channels of the upper connector 3 and the lower connector 6.
