First 3, top sealing ring 4, bottom sealing ring 5 and lower contact 6；Top sealing ring 4 and bottom sealing ring 5 are separately mounted to top connection
In 3 seal groove, top connection 3 is fixedly mounted on ejector seat, and 2 lower contacts 6 are mounted on ejection guns by mounting assembly 2
On support arm 1.
The mounting assembly 2, including support 7, cover board 8 and fastener 9；7 longitudinal cross-section of support is L-type structure, in lower section
Side be equipped with 2 same diameters semicircle orifice, mounting hole is distributed with around 2 semicircle orifices, above side have 2 it is rectangular
Mounting hole is distributed in hole above square hole；Cover board 8 is rectangular parallelepiped structure, and wherein there is the semicircle of 2 same diameters in side
Mounting hole corresponding with the mounting hole being distributed around 2 semicircle orifices on support 7 is distributed in hole, other side；Support 7 has semicircle orifice
Side and after cover board 8 has the side of semicircle orifice to fit together, it is fixed with fastener 9.
The lower contact 6 is L-type connector, has 60 ° of chamfering at connector both ends, has annular groove in longer one end, under
The annular groove of connector 6 is mounted in the semicircle orifice of support 7 and cover board 8, is fixed on mounting assembly 2.
The length of the longer one end of described two lower contacts 6 is different.
The annular groove of the lower contact 6 is mounted in the support 7 of mounting assembly 2 and the semicircle orifice of cover board 8, lower contact 6
Annular groove diameter is less than the semicircle bore dia of support 7 and cover board 8, and the height of annular groove is greater than support 7 and the semicircle orifice of cover board 8 is high
Degree.
Beneficial effects of the present invention: automatic linking quick-release coupling realizes that combustion gas passes using the structure type of floating connection
It is defeated.Automatic linking quick-release coupling has many advantages, such as that structure is simple, easy to use and convenient for safeguarding, and the ejection suitable for active service is rescued
Generating apparatus has broader practice prospect.

Specific embodiment
Below by specific embodiment, the present invention is described in further detail:
Referring to Fig. 1, a kind of automatic linking quick-release coupling, including mounting assembly 2, top connection 3, top sealing ring 4, bottom
Sealing ring 5 and lower contact 6；Top sealing ring 4 and bottom sealing ring 5 are separately mounted in the seal groove of top connection 3, top connection
3 are fixedly mounted on ejector seat, and lower contact 6 is mounted on ejection guns support arm 1 by mounting assembly 2.
When seat hangs in cockpit, 60 ° of chamfer contact at 6 ozzle of top connection 3 and lower contact, as seat is transferred, under
Connector 6 provides lateral guiding force, and lower contact 6 radially translates in mounting assembly 2, realizes top connection 3 and lower contact 6
Automatic butt.
Referring to fig. 2, the mounting assembly 2, including support 7, cover board 8 and fastener 9；7 longitudinal cross-section of support is L-type knot
Structure is equipped with the semicircle orifice of 2 same diameters in lower section side, mounting hole is distributed with around 2 semicircle orifices, side has above
2 square holes, are distributed with mounting hole above square hole；Cover board 8 is rectangular parallelepiped structure, and wherein there are 2 same diameters in side
Mounting hole corresponding with the mounting hole being distributed around 2 semicircle orifices on support 7 is distributed in semi-circular hole, other side；Support 7 has
It is fixed with fastener 9 after the side of semicircle orifice and cover board 8 have the side of semicircle orifice to fit together.Lower contact 6 can be made to exist
It is moved on mounting assembly 2 flexibly, saves space, reduce weight.
Referring to Fig. 3, the lower contact 6 is L-type connector, has 60 ° of chamfering at connector both ends, has ring in longer one end
Shape slot, the annular groove of lower contact 6 are mounted in the semicircle orifice of support 7 and cover board 8, are fixed on mounting assembly 2.
The length of the longer one end of described two lower contacts 6 is different.It can make the spacing of the semicircle orifice of support 7 and cover board 8
It minimizes, saves space, reduce weight.
The annular groove of lower contact 6 is mounted in the support 7 of mounting assembly 2 and the semicircle orifice of cover board 8, the annular of lower contact 6
Slot diameter is less than the semicircle bore dia of support 7 and cover board 8, and the height of annular groove is greater than the semicircle orifice height of support 7 and cover board 8,
Guarantee that lower contact 6 has certain free gap in mounting assembly 2, can float both axially and radially on mounting assembly 2.
When seat is transferred, the chamfer contact of bottom sealing ring 5 and lower contact 6, since the sealing principle of sealing ring is to pass through
Contact pressure is generated on sealing contact surface so that flexible deformation occurs for sealing ring by the extruding of 6 inner cavity of lower contact, thus
Realize sealing.Therefore to avoid in decentralization process bottom sealing ring 5 because the chamfering matching problem with lower contact 6 causes to fail,
To increase top sealing ring 4.Therefore top connection 3 uses Double seal ring structure, and bottom sealing ring 5 shields, avoids
Seat quickly hangs in cockpit and impacts to leakproofness, and top sealing ring 4 plays main seal.
When ejector seat starting ejection, the combustion gas of generation realizes combustion by the combustion gas transmission channel of top connection 3 and lower contact 6
Gas transmission.
