Description
Technical field
The invention belongs to technical field of aerospace, are related to a kind of aircraft bulkhead door active retaining rod mechanism.
Background technique
Currently, carrier rear deck is usually provided with airtight bulkhead, while being provided with bulkhead door, it is provided with below bulkhead door
Step.In flight course, to prevent personnel from making a misstep, personnel safety guard's problem is considered, need to limit occupant into rear landing gate
Region, at the same after need to being kept in emergency and maintenance shut-downs landing gate region it is unimpeded.One is used according to functional requirement
Kind aircraft bulkhead door active retaining rod mechanism can solve above-mentioned needs.The device is attached in composite material partition, by can
The cylindrical type lever of rotation, in the case where handrail goes to horizontality, it is possible to provide the function of limitation and handrail, in rotation to Vertical Square
To can concede channel, guarantee that channel is unimpeded.By using the device.Boarding door using security issues after can effectively solving.
Summary of the invention
The purpose of the present invention is: effectively solve the safety problem of landing gate regional channel after aircraft.
The technical solution of the invention is as follows:
A kind of aircraft bulkhead door active retaining rod mechanism, the mechanism is by body handrail, fixed mechanism, accommodating mechanism, turning engine
Structure composition；Wherein, fixed mechanism, accommodating mechanism, rotating shaft mechanism are each attached on multiple material partition, body handrail one end and turning engine
Structure is fixedly connected, and the other end is free end；In use, free end is rotated along rotating shaft mechanism to horizontality, fixed mechanism by its
It is fixed；When packing up, fixed mechanism discharges body handrail free end, and rotation to plumbness is stored by handrail accommodating mechanism
It is fixed.
The fixed mechanism is made of support, bolt, spring mechanism, and the bolt for being set with spring is assemblied in holder through-hole
It is interior；It is provided with simultaneously in body handrail free end in the pin hole of bolt cooperation, the folding and unfolding of spring and bolt cooperation completion pull rod.
The method have the benefit that: a kind of retractable armrest system proposed by the present invention is used, rotation is passed through
Handrail can carry out the switching of two states with F.F., easy to operate, effective.Solves the safety of landing gate regional channel after aircraft
Problem.Quickly handrail can be fixed by the pull ring of armrest fixing mechanism, by applying certain force under collapsed state
Storage fixation quickly can be carried out to handrail, preferably realize the effect of its storage, and will not generated and make an uproar under vibration environment
Sound.
Detailed description of the invention
Fig. 1 is a kind of aircraft bulkhead door active retaining rod structural scheme of mechanism,
Fig. 2 is rotating shaft mechanism schematic diagram,
Fig. 3 is fixed mechanism schematic diagram,
Fig. 4 is accommodating mechanism schematic diagram.
Number explanation: 1- body handrail, 2- fixed mechanism, 3- accommodating mechanism, 4- rotating shaft mechanism.
Specific embodiment
Referring to attached drawing 1-4, a kind of aircraft bulkhead door active retaining rod mechanism such as attached drawing 1, rotating shaft mechanism according to the present invention
As shown in Fig. 2, fixed mechanism such as attached drawing 3, accommodating mechanism such as attached drawing 4, the mechanism is by body handrail 1, fixed mechanism 2, storage
Mechanism 3, rotating shaft mechanism 4 form；Wherein, fixed mechanism 2, accommodating mechanism 3, rotating shaft mechanism 4 are each attached on multiple material partition, body
1 one end of handrail is fixedly connected with rotating shaft mechanism, and the other end is free end；In use, free end is rotated along rotating shaft mechanism to level
State, fixed mechanism 2 are fixed；When packing up, fixed mechanism 2 discharges body handrail free end, and rotation to plumbness passes through
Handrail accommodating mechanism 3 is stored fixation.
The fixing end of body handrail 1 is socketed in the shaft of rotating shaft mechanism 4, and body handrail 1 can be rotated along rotating shaft mechanism 4；
For the fluency for guaranteeing rotation, lubricating oil is coated in packaging clearance.In use, rotating body handrail to the limit of fixed mechanism 2
At the device of position, the movable latch of fixed mechanism 2 and the location hole of handrail side carry out grafting, guarantee the fixation to handrail；It packs up
When, the movable latch of fixed device 2 is extracted, handrail turns to plumbness, passes through damping spring card in handrail accommodating mechanism 3
Handrail is stored and is fixed.
Composite panel use for a long time in order to prevent causes Local Cracking, and multiple material partition behind junction increases metal and adds
Strong piece is required with proof strength；By the rotating function of fixed pin and swivel realization handrail in handrail rotating shaft mechanism, such as
Fig. 2；The location hole of movable latch and handrail side carries out grafting in handrail use state, fixed mechanism 2, guarantees to handrail
It is fixed, such as Fig. 3；When needing to pack up handrail, handrail is turned into plumbness, passes through damping spring in handrail accommodating mechanism 3
Handrail is stored and is fixed by card, such as Fig. 4；Protective case is housed, a side prevents handrail from contacting for a long time with spring leaf on damping spring card
Friction, causes surface scratch, on the other hand stores convenient for the unlatching of handrail.
