Description
Technical field
The utility model relates to a kind of large aerospace aircraft, is specifically related to a kind of large aerospace aircraft with hatch door start-stop system, belongs to field of aviation machinery.
Background technology
Aviation aircraft structure generally comprises multiple hatch door, such as cabin door, cargo door, maintenance door (hatch cover) and undercarriage door.These hatch doors provide the path leading to aviation aircraft inside when opening, and close time with around aviation aircraft structure consistent.The importance of hatch door is that hatch door opens and closes other parts that must prevent from colliding, block or contact aviation aircraft structure at their opening procedure and their open position.When relative hour of the space length that the space shared by hatch door is large and required, then there will be problem.Exist in prior art and there is the aviation aircraft of two parts hatch doors, but hatch door opens and closes and needs to provide larger gap, and, for opening and closing mechanism's more complicated of hatch door, launch or folding process longer, need to spend more power.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of large aerospace aircraft with hatch door start-stop system, and the space shared by the hatch door of this large aerospace aircraft is little, can save opening and closing time and power, is convenient to open hatch door fast.
The technical solution of the utility model is as follows:
There is a hatch door start-stop system's large aerospace aircraft, comprise body, wing; Described wing is connected to the both sides of fuselage, and described body comprises outer cabin and independent tank, and described independent tank is arranged at the inside in described outer cabin, and hatch door start-stop system is arranged at the upper opening place in the outer cabin of described body; Described hatch door start-stop system includes the first hatch door plate, the second hatch door plate, the 3rd hatch door plate, extensible member, first connecting rod and second connecting rod; Described first hatch door plate the first point of connection place and outer cabin opening part hinged; Described second hatch door plate and described first hatch door plate hinged; Described 3rd hatch door plate and described second hatch door plate hinged; Described first connecting rod and described first hatch door plate and the 3rd hatch door plate hinged; Described second connecting rod and described second hatch door plate and outer cabin hinged; Described extensible member one end and outer cabin hinged, the other end and described first hatch door plate hinged.
Wherein, described hatch door start-stop system is also provided with pressure detection mechanism.
The utility model has following beneficial effect:
1, hatch door start-stop system of the present utility model, the space shared by hatch door is little, can save time and the power of keying, is convenient to open hatch door fast;
2, the utility model structure is simple, reasonable in design, and hatch door is opened conveniently.

Fig. 2 is the structural representation of hatch door start-stop system deployed condition of the present utility model;
Fig. 3 is the structural representation of hatch door start-stop system folded state of the present utility model;
In figure, Reference numeral is expressed as:
The outer cabin of 1-body, 2-wing, 3-, 31-hatch door start-stop system, 301-first hatch door plate, 302-second hatch door plate, 303-the 3rd hatch door plate, 307-extensible member, 315-first connecting rod, 319-second connecting rod, 4-independent tank.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
See Fig. 1-3, a kind of large aerospace aircraft with hatch door start-stop system, comprises body 1, wing 2; Described wing 2 is connected to the both sides of fuselage 1, and described body 1 comprises outer cabin 3 and independent tank 4, and described independent tank 4 is arranged at the inside in described outer cabin 3, and described hatch door start-stop system 31 is arranged at the upper opening place in the outer cabin 3 of described body 1;
Described hatch door start-stop system 31 includes the first hatch door plate 301, second hatch door plate 302, the 3rd hatch door plate 303, extensible member 307, first connecting rod 315 and second connecting rod 319; Described first hatch door plate 301 the first point of connection place and outer cabin 3 opening part hinged; Described second hatch door plate 302 is hinged with described first hatch door plate 301; Described 3rd hatch door plate 303 is hinged with described second hatch door plate 302; Described first connecting rod 315 and described first hatch door plate 301 and the 3rd hatch door plate 303 hinged; Described second connecting rod 319 and described second hatch door plate 302 and outer cabin 3 hinged; Described extensible member 307 one end and outer cabin 3 hinged, the other end and described first hatch door plate 301 hinged;
Described first connecting rod 315, second connecting rod 319 close the first hatch door plate 301, second hatch door plate 302, the 3rd hatch door plate 303, form single hatch door, and when open, the first hatch door plate 301 drives remaining part to move substantially simultaneously.
Wherein, described hatch door start-stop system 31 is also provided with pressure detection mechanism (not shown).
Use principle of the present utility model: the first hatch door plate, the second hatch door plate, the 3rd hatch door plate form four-bar linkage together with first connecting rod.This four-bar linkage is activated by second connecting rod, and this second connecting rod is being connected to outer cabin structure with the isolated position of the trunnion of the first door members and is being used as basic connecting rod.The actuating movement that this four-bar linkage system makes second connecting rod be produced by folding and unfolding extensible member can be delivered to each element in four connecting rod mechanisms substantially, thus opens or closes hatch door.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
