Abstract
The utility model provides a hatch door order difference adjustment mechanism, a serial communication port, including fix lock ring holder (1) on the hatch door, with the eccentric catch (2) of latch hook complex, install in the mounting hole of lock ring holder (1) tip eccentric catch (2) for adjustment catch and latch hook assembly error.
Description
Technical field
The invention belongs to aviation field, particularly relate to a kind of can be used for undercarriage hatch door, in bury adjustable upper lock ring on the various aerial jacks such as weapon hatch door, flap, drag parachute housing, extendible air refueling pipe.
Background technology
Modern combat aircraft proposes high requirement to Stealth Fighter, and for meeting Stealth Fighter needs, the jacks such as hatch door are on receiving during state, and hatch door surrounding will overlap with fuselage skin, and strictly will control jump.
Due to upper lock ring, above-below direction is adjustable after mounting in the present invention, thus the aerial folding structure such as hatch door can well be controlled after locking, overlap jump with fuselage skin, good effect is served to the RCS reducing the folding structures such as hatch door, thus improves the Stealth Fighter of aircraft.When being provided with jump with front door mechanism, the lock ring or by producing new parts of need polishing, controls quality of fit, existing makes adjustment jump become simple by the present invention, easy.
Summary of the invention
The present invention proposes the hatch door jump regulating mechanism that a kind of structure is simple, easy to adjust, lightweight, reliability is high, applied widely.
The invention provides a kind of hatch door jump regulating mechanism, it is characterized in that, the eccentric lock ring (2) comprise the lock ring support (1) be fixed on hatch door, coordinating with latch hook, eccentric lock ring (2) is arranged in the mounting hole of lock ring support 1 end, for adjusting lock ring and latch hook assembly error.
Further, described eccentric lock ring (2) comprises edge with the cylindrical matrix (2-1) protruding block (2-2), cylindrical matrix (2-1) is provided with off-center column (2-3), off-center column (2-3) coordinates with latch hook, lock ring support (1) end has multiple adjusting grooves (1-1), by protruding coordinating of block (2-2) and adjusting grooves (1-1) of diverse location, off-center column (2-3) location deflection, realizes the adjustment of lock ring and latch hook assembly error.
Further, described off-center column (2-3) comprises lock ring sleeve (2-4), lock ring sleeve (2-4) is enclosed within off-center column (2-3), and off-center column (2-3) is coordinated with latch hook by lock ring sleeve (2-4).
Further, described lock ring sleeve (2-4) adopts hardness lower than the material of latch hook and off-center column (2-3).Realize the protection to latch hook and lock ring, improve reliability, strengthen its interchangeability.
Further, lock ring sleeve (2-4) adopts copper material.Larger than the material hardness of latch hook and lock ring, avoid organism material impaired, realize, to its protection, improve the reliability of aircraft.
Further, also comprise eccentric sleeve (3), eccentric sleeve (3) is arranged on eccentric lock ring (2) one end, and eccentric sleeve (3) is arranged in the mounting hole of lock ring support (1) end.Eccentric sleeve (3) can make eccentric lock ring (2) longer for service life.And eccentric sleeve (3) is easy to change.
Further, eccentric sleeve (3) is provided with the chute of logical grease.
Applied range of the present invention, be applicable to undercarriage door, in bury the various aerial folding structures such as weapon hatch door, flap, drag parachute housing, the aerial collection tube of extendible, the present invention can adjust the position of folding structure uplock easily, the jump that control folding structure and fuselage overlap, greatly fall folding structure RCS, improve the Stealth Fighter of aircraft.
Volume of the present invention is little, lightweight, easy to adjust, need not polish, and general, interchangeable, reliability is high.

Detailed description of the invention
The invention provides a kind of hatch door jump regulating mechanism, the eccentric lock ring 2 comprise the lock ring support 1 be fixed on hatch door, coordinating with latch hook, eccentric lock ring 2 coordinates with eccentric sleeve 3, is arranged on lock ring support 1 end, for adjusting lock ring and latch hook assembly error.
Eccentric lock ring 2 comprises the cylindrical matrix 2-1 of edge with outstanding block 2-2, cylindrical matrix is provided with off-center column 2-3, off-center column 2-3 coordinates with latch hook, lock ring support 1 end has multiple adjusting grooves 1-1, by coordinating of the adjusting grooves 1-1 of outstanding block 2-2 and diverse location, off-center column 2-3 location deflection, realizes the adjustment of lock ring and latch hook assembly error.
Off-center column 2-3 comprises lock ring sleeve 2-4, and lock ring sleeve 2-4 is enclosed within off-center column 2-3, and off-center column 2-3 is coordinated with latch hook by lock ring sleeve 2-4.
Lock ring sleeve 2-4 adopts hardness lower than the copper product of latch hook and off-center column 2-3.
Eccentric sleeve 3 is arranged on eccentric lock ring 2 one end, and eccentric sleeve 3 is arranged in the mounting hole of lock ring support 1 end.Eccentric sleeve 3 can make eccentric lock ring 2 longer for service life.And eccentric sleeve 3 is easy to change.
Further, eccentric sleeve 3 is provided with the chute of logical grease.
Hatch door or other locked object are when uplock is installed, the relative position of the eccentric protrusion block 2-2 of the lock ring 2 and adjusting grooves 1-1 of lock ring support 1 of adjustable, the adjustment realizing lock ring height direction is changed by the degree of eccentricity of eccentric lock ring 2, the upper lock ring of adjustable hatch door can meet folding structure lock install time height direction adjustment, finally reach the folding structures such as hatch door and the requirement meeting jump and control is installed, reduce RCS, improve aircraft Stealth Fighter.
