Up-small and down-big step pore structure is used by hole 11, internal thread is opened up on the lower half perisporium by hole 11, and allow and pass through
The table top of the lower and upper parts junction of hole 11 uses concave spherical surface, meanwhile, multiple bar shaped fixing holes 12 are set in supporting plate 1
In order to carry out installing fixed and adjustment position.Ozzle joint 21 is correspondingly arranged in the lower end of air supply pipe 2 and upper end and intubation connects
First 22, limited ring dais 23 are set on the periphery wall of ozzle joint 21, and the upper side of limited ring dais 23 and downside is adopted
Use convex spherical；Two seals annular groove 24 is set on the periphery wall of spigot joint 22 and the sealing of O shapes is set in closure gasket groove 24
Circle 25.The ozzle joint 21 that allows on a plurality of air supply pipe 2 is corresponding from multiple by being passed through in hole 11 in supporting plate 1, and leads to respectively
Cross limit casing 3 ozzle joint 21 is carried out it is spacing.Wherein, the limited ring dais 23 allowed on ozzle joint 21 are in by hole 11
Table top on the downside of, and ozzle joint 21 and limited ring dais 23 is coordinated with passing through the internal perisporium interval in hole 11；Limit casing 3 is allowed to exist
Limit baffle ring 31 is set on its periphery wall, and make its first half spinning in supporting plate 1 by hole 11, limit casing 3
Upper end is in the downside of limited ring dais 23 of ozzle joint 21, and makes the internal perisporium of limit casing 3 and the periphery wall of ozzle joint 21
Gap coordinates.
A kind of simple in construction, easy to operate, sealed reliable, adaptable support formula are just constituted by above structure setting
Rocket supplies connector.In actual applications, allow supporting plate 1 by multiple bar shaped fixing holes 12 and corresponding be bolted to pair
On the support that should be set, and position is adjusted so that it allows with supplying the centering of socket 4 on arrow by multiple bar shaped fixing holes 12
The ozzle joint 21 of a plurality of lower end of air supply pipe 2 is corresponding to be connected with source of the gas, allows the spigot joint 22 of a plurality of upper end of air supply pipe 2 is corresponding to insert
Enter the air feed interface 41 supplied on arrow on socket 4, you can realize the rapid abutting joint and combined air supply of air source device pipeline.The present invention
By setting two seals annular groove 24 and corresponding O-ring seals 25 on spigot joint 22, inserted in spigot joint 22 on arrow
When supplying the air feed interface 41 on socket 4, reliable sealing can be achieved by extruding O-ring seals 25.Taken off in rocket firing
When, supply socket 4 can make each air feed interface 41 overcome frictional force directly to be connect with each intubation in rocket uphill process is followed on arrow
First 22 depart from, it is not necessary to which unlocking motion can be such that supply connector realizes zero second to come off, and have and dock convenient and swift, come off reliable
The advantages of.Meanwhile the present invention uses concave spherical surface in supporting plate 1 by allowing by the table top in hole 11, the periphery of ozzle joint 21 is allowed
The upper side of wall upper limit land 23 and downside use convex spherical, allow ozzle joint 21 and limited ring dais 23 with by hole 11
Internal perisporium interval coordinate, the spacing of above-below direction is carried out to ozzle joint 21 by limit casing 3, and allow limit casing 3
The periphery wall gap of internal perisporium and ozzle joint coordinates, and on the basis of structure relative stability is ensured, makes ozzle joint 21 can
Rotate and micro deflection can be realized.When rocket firing is taken off, ozzle joint 21 can be followed on arrow and supplied this structure setting
Air feed interface 41 on socket 4 carries out micro skew and reversed, and to adapt to the micro drift and rolling when rocket body takes off, improves confession
The adaptability and practicality of air connector.It should be noted that in actual applications, the upper end of limit casing 3, ozzle joint 21
On limited ring dais 23 and slightly measure gap by that should be left between the table top in hole 11, to ensure ozzle joint 21 in the horizontal direction
On can do it is micro skew reverse.Closure gasket groove 24 on spigot joint 22 is not limited to set twice, can also set one or two
More than road, as long as reliable sealing can be realized and come off for zero second.Above-mentioned supporting plate 1 refers to prop up with supplying the centering of socket 4 on arrow
It is multiple corresponding with supplying the centering of air feed interface 41 on socket 4 on arrow by hole 11 on fagging 1.
As embodiment, the fixing hole 12 that the present invention allows in supporting plate 1 sets six, wherein four fixing holes 12
Corresponding four angles for being distributed in supporting plate 1, another two fixing hole 12 are distributed in the middle part of the one end of supporting plate 1.This setting has
Adjustment position is convenient and swift, connects the characteristics of reliable.To improve the convenience of operation, present embodiment also allows limit casing
3 have opened up on the periphery wall of the downside of limit baffle ring 31 and symmetrically have risen as high as the banks, to facilitate tool engagement progress rotation process.In addition.
In actual applications, the generally use steel pipe of air supply pipe 2 in the present invention, makes it to bear certain bending, to improve connector
Adaptability.It is pointed out that air supply pipe 2 is not limited to use steel pipe, can also use has its for being equal to property with steel pipe
The pipe fitting of his type.
To help skilled in the art to understand the present invention, connector is supplied to a kind of brace type rocket of the present invention below
Installation and the process docked with supplying socket 4 on arrow make schematic illustration：
1st, it respectively will outwards be screwed out by the limit casing 3 in hole 11 in supporting plate 1, each air supply pipe 2 is fallen after rise downwards, so as to
Reserve operating space.
2nd, supporting plate 1 is arranged on the support being correspondingly arranged by fixing hole 12 and corresponding bolt, and makes supporting plate 1
With supplying the preliminary centering of socket 4 on arrow.Now, each bolt is in the state that unscrews to carry out fine position to supporting plate 1.
3rd, any two air supply pipes 2 are above carried, the spigot joint 22 of its upper end is inserted and corresponding confession on socket 4 is supplied on arrow
In gas interface 41.
4th, finely tune supporting plate 1 position, when two air supply pipes 2 be in corresponding to hit exactly by hole 11 when, screwed support
Bolt on plate 1 is so that it is fixed with support, and screws in limit casing 3 corresponding to two air supply pipes 2 inwards.
5th, remaining air supply pipe 2 is above carried, the spigot joint 22 of its upper end is inserted and corresponding supply on socket 4 is supplied on arrow
In interface 41, and limit casing 3 corresponding to each air supply pipe 2 is screwed in inwards.
Our experiments show that, a kind of brace type rocket supply connector of the present invention can realize long-term docking and effectively sealing, and
The micro drift and rolling when rocket takes off are adapted to, and it is zero that supply connector and rocket body can be achieved not need unlocking motion
Second comes off.In addition, the supporting plate 1, air supply pipe 2 and limit casing 3 in the present invention employ modularized design, it is easy to accomplish,
Commutativity is good, is advantageous to carry out each part during execution task quick-replaceable, maintenance.
Above example is only the description carried out to the preferred embodiment for the present invention, and scope not is claimed to the present invention
The restriction of progress, on the premise of design spirit of the present invention is not departed from, technology of this area engineers and technicians according to the present invention
The various forms of deformations that scheme is made, it all should fall into the protection domain of claims of the present invention determination.
