Abstract
The invention relates to the field of machines, and provides a helicopter sliding cabin door spacing mechanism. The mechanism comprises a shell having a cavity and fixed in a position near to a cabin door on a cabin, a bolt is installed in the shell cavity, the front end of the bolt stretches out of the front end of the shell, traverses through an opening on a cabin sliding rail and enter a sliding rail slot, the rear end of the bolt is fixedly provided with a sliding rod, the tail end of the sliding rod traverses through the rear end of the shell and is connected with a poke rod, the sliding rod is sleeved with a spring, the spring is spaced between the rear end of the bolt and the rear end of the shell, each of the shell and the poke rod is provided with an oblong hole, the tail end of the sliding rod corresponding to the oblong holes of the shell and the poke rod is also provided with a hole, the tail end of the sliding rod traverses through the rear end of the shell, and one flat head shaft sequentially traverses through the holes of the poke rod, the shell and the tail end of the sliding rod to connect the poke rod, the shell and the sliding rod; and one flat head shaft sequentially traverses through the oblong holes on the poke rod and the shell as a transmission shaft of the poke rod. After the spacing mechanism is installed on a sliding cabin door, the operation is simple and the maintainability is strong.
Description
Technical field
The present invention relates to mechanical field, relate in particular to a kind of helicopter sliding nacelle door limiting mechanism.
Background technology
The helicopter of home and abroad is equipped with slip hatch door mostly, when carrying out some task, must open slip hatch door aloft, but hatch door automatically slides back to and close sometimes after aloft opening, and brings danger to aerial work personnel.
Summary of the invention
The technical problem to be solved in the present invention: a kind of helicopter sliding nacelle door limiting mechanism is provided, can effectively prevents that hatch door from closing automatically.
Technical scheme of the present invention: a kind of helicopter sliding nacelle door limiting mechanism, comprise: the housing that is fixed on nearly hatch door place, cabin band cavity, in described housing cavity, be inserted with dead bolt, described dead bolt front end stretches out housing front end, through the opening on hatch door slide rail, enter sliding-rail groove, described dead bolt rear end is fixing with a slide bar, described slide bar tail end is connected with poke rod through housing rear end, described slide bar overcoat has spring, described spring is spacing between dead bolt rear end and housing rear end, on housing and poke rod, have obround opening, on slide bar tail end corresponding housing and poke rod, obround opening position is also provided with perforate, housing tail end is two fork ear structures, poke rod is also two fork ear structures, slide bar tail end is through housing rear end, and a tack axle, successively through the perforate of poke rod, housing and slide bar tail end, links together them, a tack axle is successively through the round hole on poke rod and housing, as the turning cylinder of poke rod.
Beneficial effect of the present invention: slip hatch door is installed after this position-limit mechanism, makes limit function more reliable, and simple to operate, maintainable strong.
Accompanying drawing explanation
Fig. 1 is the front view of helicopter sliding nacelle door limiting mechanism structure schematic diagram of the present invention.
Fig. 2 is the top view of helicopter sliding nacelle door limiting mechanism structure schematic diagram of the present invention.
The specific embodiment
For better explanation the present invention, provide one embodiment of the present invention below.
Referring to Fig. 1 and Fig. 2, is the structural representation of an embodiment of helicopter sliding nacelle door limiting mechanism of the present invention.This cover slide position-limit mechanism is arranged on straight nine series helicopters, and it is mainly comprised of several parts below:
A) end of the housing 1 of limit assembly has perforate, is that hole axle coordinates with the slide bar of dead bolt 2, and spring 6 is enclosed within on the slide bar of dead bolt 2, and the slide bar of dead bolt 2 is connected with poke rod 3 through after the perforate of housing 1 end.
C) between housing 1 and poke rod 3, also by tack axle 10, packing ring 11, cottor pin 12, be connected, and tack axle 10 is as the turning cylinder of poke rod in position-limit mechanism 3.
D) simultaneously, on housing 1 and poke rod 3, have obround opening, with solving in rotation process because the radius of gyration changes the problem of bringing.
E) column 4, by the perforate of poke rod 3 ends, is connected with self-locking nut 13, is convenient to poke rod 3 to operate.
F) limit assembly links together by bolt 6 and housing construction, and dead bolt 2 enters into sliding-rail groove by the opening on slide rail 14 simultaneously, plays slip hatch door roller 15 is carried out to spacing effect.
The end of the housing 1 of limit assembly has perforate, be that hole axle coordinates with the slide bar of dead bolt 2, spring 6 is enclosed within on the slide bar of dead bolt 2, and the slide bar of dead bolt 2 links together by tack axle 7, packing ring 8, cottor pin 9 with housing 1, poke rod 3 through after the perforate of housing 1 end.
Between housing 1 and poke rod 3, also by tack axle 10, packing ring 11, cottor pin 12, be connected.
Limit assembly links together by bolt 6 and housing construction, and dead bolt 2 enters into sliding-rail groove by the opening on slide rail 14 simultaneously, plays slip hatch door roller 15 is carried out to spacing effect.When opening the door, slide roller 15 is by dead bolt 2, drive after dead bolt 2 Compress Springs 5, passage is opened wide in formation, roller 15 dead bolt 2 that can roll easily, and slide roller 15 is by after dead bolt 2, dead bolt 2 is subject to the elastic force effect of spring 5, return to initial position, pair roller 15 positions limit, and play position-limiting action.At closing time, only need to stir gently the column 4 being connected with poke rod 3, the latch lock on position-limit mechanism just can be opened easily, slide rail internal channel is opened wide, thereby closed hatch door.
Because the position-limit mechanism of new model has adopted simple latch mechanism form, so just had its exclusive feature: when opening the door, slide roller, by dead bolt, drives after dead bolt Compress Spring, forms and opens wide passage, the roller dead bolt that can roll easily, slide roller is by after dead bolt, and dead bolt is subject to the elastic force effect of spring, returns to initial position, pair roller position limits, and plays position-limiting action.At closing time, only need to stir gently poke rod, the latch lock on position-limit mechanism is opened, slide rail internal channel is opened wide, thereby closed hatch door.
