Description
Technical field
The present invention relates to a kind of passenger plane hatch door pressure locking mechanism, specifically it is applied to for one kind on passenger plane hatch door,
The hatch door transmission mechanism of ventilating opening locking is opened and realized under given conditions for linkage complete air port.
Background technology
For passenger plane hatch door, air worthiness regulation AC25.783 regulations：Should have prevents from opening hatch door under uneasy total pressure
Measure.At present, generally realize that this is required using flight latch mechanism.Flight latch mechanism space-consuming is big, cost is high, weight is big, grinds
Zhi Shixu suppliers participate in, and the lead time is long.A small number of advanced type door designs ventilating opening pressure latch mechanism, locks instead of flight
Function, but the design of Prssure lock is usually relatively complex, and part is more, and space-consuming is big, weight weight.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of passenger plane hatch door pressure locking mechanism, the locking mechanism is used for visitor
Ventilating opening pressure latch mechanism on cabin door, the mechanism has security good, and versatility is high, occupies little space, part utilization rate
Height, lightweight advantage.
To solve problem above, concrete technical scheme of the invention is as follows：A kind of passenger plane hatch door pressure locking mechanism, has
The vent assemblies that are hinged with cabin door structure, connecting rod, with the Y-piece that cabin door structure is hinged collectively form four in conjunction with cabin door structure
Linkage；Upper roller and bottom roller are respectively equipped with the forked ends of Y-piece, and cam-swing-bar mechanism is constituted with cam, it is convex
Wheel is coaxially connected with hatch door handle；Ventilating opening rotating shaft on vent assemblies 1 is provided with torsion spring, and one end acts on ventilation
On mouth component, the other end is acted in cabin door structure, and its torsion spring power makes vent assemblies have the trend opened.
When normally-open, described torsion spring driving vent assemblies are opened, upper roller and cam contact.
When realizing pressure lock function, described torsion spring torsion does not work, roller and cam contact.
By adjusting the torque magnitude of torsion spring, the pressure value of control control vent assemblies Opening pressure locking.
The passenger plane hatch door pressure locking mechanism has the following advantages that：
1st, the mechanism integrated level is high, saves a set of flight latch mechanism.The present invention can be directly integrated into ventilating opening and open machine
On structure, without unnecessary mechanism is added, compared to using scheme of the flight latch mechanism as pressure locking mechanism, it can design less
A set of mechanism, this greatlys save space and weight, reduces design difficulty and design cost, and these are designed for civil aircraft
It is particularly important；
2nd, number of parts is few, and utilization rate is high.In the present invention, Prssure lock latch hook and matched roller are all integrated into
On ventilating opening opening mechanism, without individually designed part.The transmission of pressure locking mechanism, it is also ingenious to make use of ventilating opening to open machine
Structure is realized, part utilization rate is substantially increased, so as to further save space and weight；
3rd, mechanism is simple, applied widely.Mechanism driving relation of the present invention is simple, use be all conventional and very into
Ripe typical mechanism, two kinds of functions are realized by ingenious combination.The present invention can be widely applied on various types of hatch doors；
4th, the pressure value of Opening pressure lock function can accurately be controlled.The present invention can be by adjusting the big of torsion spring torsion
It is small, the corresponding hatch door boost values of Opening pressure lock function are accurately controlled, and can be easily according to different
Type is adjusted.
Brief description of the drawings
Fig. 1 is the axonometric drawing of passenger plane hatch door pressure locking mechanism.
Fig. 2 is hatch door ventilating opening normally open state schematic diagram.
Fig. 3 is that hatch door ventilating opening pressure locks view.
Embodiment
As shown in figure 1, a kind of passenger plane hatch door pressure locking mechanism, with the vent assemblies 1 being hinged with cabin door structure, even
The Y-piece 7 that bar 2 and cabin door structure are hinged collectively forms four-bar mechanism in conjunction with cabin door structure；In the forked ends of Y-piece 7
Upper roller 3 and bottom roller 8 are respectively equipped with, and cam-swing-bar mechanism is constituted with cam 4, cam 4 and hatch door handle are coaxially connected；
Ventilating opening rotating shaft 5 on vent assemblies 1 is provided with torsion spring 6, and the one end of torsion spring 6 is acted on vent assemblies 1, and the other end is made
For cabin door structure, its torsion spring power makes vent assemblies 1 have the trend opened.
As shown in Fig. 2 when normally-open, the described driving vent assemblies 1 of torsion spring 6 are opened, and upper roller 3 connects with cam 4
Touch.
As shown in figure 3, when realizing pressure lock function, the described torsion of torsion spring 6 does not work, and roller 8 connects with cam 4
Touch.
By adjusting the torque magnitude of torsion spring 6, the pressure value of control vent assemblies 1 Opening pressure locking.
This passenger plane hatch door pressure locking mechanism is comprising ventilating opening is normally-open and pressure locks two kinds of functions.In this set mechanism
The spring force of torsion spring 6 make the trend that ventilating opening has the supercharging load in opening trend, cabin to make ventilating opening have closing.Work as cabin
When the torque that interior supercharging load is produced is less than spring torque, the inwardly rotation under spring force of vent assemblies 1 causes
Roller 3 is pressed on the surface of cam 4.In initial position, cam 4 is in arc section, and roller 3 passes through cam to the pressure of cam 4
Axle center, mechanism driving angle is zero, and cam 4 is in situ motionless.When moving the band rotation of moving cam 4 of hatch door handle, roller 3 continues
The surface of cam 4 is compressed under spring force.Trajectory of the roller 3 along cam 4 is moved, so that link by Y-piece 7,
The four-bar mechanism of connecting rod 2, ventilating opening 1 and cabin door structure composition is rotated, and realizes the normally-open of ventilating opening.Ventilating opening is normal
Open mode is as shown in Figure 2.
When the torque that the supercharging load in cabin is acted on ventilating opening is more than the torque that torsion spring 6 is produced, ventilating opening group
Part 1 will be pressed in cabin door structure by supercharging load.Now, move handle band moving cam 4 to rotate, Y-piece 7 keeps in situ, rolling
Wheel 3 is separated with cam 4.It is rotated further handle band moving cam 4 to rotate, the lower rail trace of cam 4 starts to contact with roller 8.It is convex
The similar latch hook of lower rail trace profile of wheel 4, so " cam-swing rod " mechanism that cam 4 is constituted with roller 8 and Y-piece 7
Drive line angle very little with very big power driving cam 4, it is necessary to could drive Y-piece 7 to rotate, so as to drive ventilating opening 1 to open.
By the latch hook of the bottom of cam 4, the pressure lock function of hatch door is realized.Ventilating opening pressure lock-out state is as shown in Figure 3.
