Description

A kind of guided missile records cabin hatch structure

Technical field

The invention belongs to missile airframe structure, relate to the improvement of guided missile being recorded to cabin hatch structure.

Background technology

Certain small size air air-to-air missile (AAM) dummy round records cabin and is mainly used to record dummy round in flight trainingThe various data of parameters and pilot operator, judge whether pilot's operation meets specification.After flight training end aircraft lands, first to open the hatchcover that records cabin, carry out dataDownload, remove the operations such as record, then build hatchcover and wait for flight training next time. Due to flightFrequent training, user wishes to record the disassembling section of cabin hatch cover panel can be flexibly, simple, fastPrompt, convenient, open rear deck lid and screw and do not come off, be connected with cabin body all the time, and hatch boardAlso need to there is sealing protection, safe and reliable function. The existing cabin hatch structure that records is: have oneIndividual with rectangle hatch record cabin housing 1, be embedded in the hatch board 2, on above-mentioned rectangle hatchThe individual rectangle hatch below that is positioned at is screwed in the window body 3 recording on the skeleton of cabin, window body 3 footpathsBe slightly larger than the rectangle of above-mentioned rectangle hatch profile to the rectangle of direction profile, the outer surface of window body 3For the arc surface concentric with recording cabin housing 1, the radius of window body 3 outer surfaces with record cabin housing 1Internal diameter identical, the inner surface of window body 3 is plane, hatch board 2 is by multiple screws and windowThe outer surface of body 3 connects, and the outer surface of hatch board 2 is coplanar with the periphery that records cabin housing 1,Between hatch board 2 and the outer surface of window body 3, there is the cyclic sealing gasket 4 of a rectangle, at windowThere is a rectangular through-hole 5 of holding rectangular receptacle the centre of body 3, on the outer surface of window body 3, hasA seal groove 6 around rectangular through-hole 5, sealing ring 7 is arranged in seal groove 6. This hatchThe disassembling section complexity of structure, the consumption time is long; And separate with cabin body after hatch board dismounting, holdEasily lose or polluted.

Summary of the invention

The object of the invention is: propose a kind of hinged cabin hatch structure that records that adopts, make cabinThe disassembling section of velar plate can be flexible, simple, quick and easy, opens rear deck lid and screwDo not come off, be connected with cabin body all the time, and there is sealing protection, safe and reliable feature.

Technical scheme of the present invention is: a kind of guided missile records cabin hatch structure, comprises with rectangular cabinMouthful record cabin housing 1,2, one of hatch boards that are embedded on above-mentioned rectangle hatch are positioned at rectangular cabinBelow mouthful, be screwed in the window body 3 recording on the skeleton of cabin, window body 3 radial direction profilesRectangle is slightly larger than the rectangle of above-mentioned rectangle hatch profile, and the outer surface of window body 3 is and records cabin shellThe arc surface that body 1 is concentric, the radius of window body 3 outer surfaces is identical with the internal diameter that records cabin housing 1,The inner surface of window body 3 is plane, and hatch board 2 is connected with the outer surface of window body 3 by screw,The outer surface of hatch board 2 is coplanar with the periphery that records cabin housing 1, in hatch board 2 and window body 3Outer surface between have the cyclic sealing gasket 4 of a rectangle, have one to hold in the centre of window body 3The rectangular through-hole 5 of rectangular receptacle has one around rectangular through-hole 5 on the outer surface of window body 3Seal groove 6, sealing ring 7 is arranged in seal groove 6, it is characterized in that hatch board 2 and window body3 connect by spring hinge, and its concrete structure is as follows:

(1) between side of window body 3 and rectangular through-hole 5, there is a rectangle through hole 8,The long limit of this rectangle through hole 8 is parallel to the axial direction that records cabin housing 1, at rectangle through hole 8The mid portion of medial surface 9 have two screwed holes, respectively have one to hang down in the both sides of two screwed holesStraight in the narrow groove 10 of rectangle through hole 8;

(2) have a spring shaft 11, it is connected by two pivots 12, one end and the pivot 12 at two endsTwo two circle wind springs 13 that connect and the rotating shaft 14 that connects two two circle wind spring 13 other ends form,Pivot 12 is perpendicular to the wind spring plane of two circle wind springs 13, and rotating shaft 14 is parallel with pivot 12 and keepDistance of shaft centers d=6-12mm; Distance between two two circle wind springs 13 equals rectangle through hole 8 medial surfacesThe centre-to-centre spacing of two narrow grooves 10 on 9, the rotating shaft 14 on spring shaft 11 be positioned at two narrow grooves 10 itBetween medial surface 9 on, two individual pen wind springs 13 lay respectively in two narrow grooves 10; There is a bandHave the spring support 15 that connects half slot, its length is less than two distances between two circle wind springs 15, passes throughScrew 16 is fixed to spring support 12 on two medial surfaces 9 between narrow groove 10, by spring shaft 11Compress;

(3) at hatch board 2 lateral edges corresponding with rectangle through hole 8 in window body 3 with twoThe position of 17, two lugs 17 of individual lug is corresponding with two pivots 12 on spring shaft 11 respectively,On lug 17, record the axial axis hole of cabin housing 1 with being parallel to, two pivots 12 are inserted respectivelyEnter in two axis holes; The outer rim of said lug 17 is protruded the edge of hatch board 2, its projectionBe stuck in the rim under surface that records cabin housing 1 rectangle hatch; Hatch board 2 with two lugsThere is a screw hole at 17 another relative edges, said by outside hatch board 2 and window body 3The screw that surface connects is one and do not deviate from screw 18, and it is screwed in the screwed hole of window body 3, willHatch board 2 is pressed in window body 3.

Advantage of the present invention is: the present invention has overcome the difficulty that hatch tegmental wall is thin, hinge can not be installed,Make hatch board 2 and window body 3 realize chain connection, make the disassembling section of hatch cover panel very cleverAlive, simple, quick and easy, open rear deck lid and screw and do not come off, be connected with cabin body all the time,And there is sealing protection, safe and reliable feature. Meanwhile, structure of the present invention is small and exquisite simple, addsWork is easy, easy for installation, and cost is low.
