Abstract

The utility model provides a folding rotor wing of a rotorcraft. The folding rotor wing comprises a first wing section, a second wing section, a bent joint and a fixed sliding sleeve, wherein the first wing section is provided with a spread fixing hole; the second wing section is provided with a folding fixing hole; the two ends of the bent joint are fixedly connected with one end of the first wing section and one end of the second wing section respectively; the fixed sliding sleeve is provided with bolt holes and slidably sleeved on the bent joint and the outer faces of the first wing section and the second wing section to limit the bending of the bent joint or slides to the second wing section to expose the bent joint out so as to bend; and the bolt holes are selectively aligned with the spread fixing hole and the folding fixing hole and fixed by bolts respectively. The first wing section and the second wing section can be conveniently spread and connected onto a plane when being used and can be folded and attached together when being stored, so that the carrying and the storage can be greatly facilitated.

Description

The folding rotor of cyclogyro

Technical field

The utility model relates to a kind of rotor of cyclogyro, relates in particular to a kind of folding rotor of cyclogyro.

Background technology

Cyclogyro is former to be a kind of ancient type, comes out early than helicopter.But the back is because of the comfort feature of the invention of helicopter and vertical takeoff and landing, be early stage cyclogyro can not, thereby cyclogyro had been eliminated at that time.Near for some years because the generation of up-to-date technology makes this ancient machine be paid attention to by people again, it simple in structure, control conveniently, easy maintenance and high security have been subjected to attention, are more and more used in leisure physical culture among the people and military activity.This kind rotor craft is compared with traditional aircraft, though structure has been simplified a lot, it is bigger that its integral frame still seems, is unfavorable for transportation and storage; Store this kind aircraft and will occupy sizable interior space, this has just brought very big difficulty for domestic consumer; In use, also need to use fairly large transport vehicle and this kind aircraft is transported to the place to use, inconvenience equally very.

Rotor is installed on the top of cyclogyro, adjusts its angle of facining the wind and can make it produce buoyancy.The length of its expansion may surpass 4m, is unfavorable for very much storing and carrying.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of folding rotor of being convenient to store and carry cyclogyro simultaneously easy to use again.

The folding rotor of this cyclogyro comprises:

One first section wing has the expansion fixed orifice on this first section wing;

One second section wing has folding fixed orifice on this second section wing;

One bending joint, the two ends in this bending joint are fixedly linked with an end of first section wing and an end of second section wing respectively; With

One fixing sliding sleeve, this fixedly has pin hole on the sliding sleeve;

Should be fixedly sliding sleeve entangle the lateral surface of this bending joint and this first and second section wing slidably, or slide into the lateral surface of second section wing, this pin hole this expansions fixed orifice that optionally aligns folds fixed orifice with being somebody's turn to do, and fixes with latch respectively.

Described fixedly sliding sleeve has the section that matches with first and second section wing.

Described bending joint is a biaxial hinge.

The two ends in described bending joint respectively with an end riveted and fixed of this first section wing and second section wing.

Have two on described first section wing and launch fixed orifice, have two folding fixed orifices on second section wing, fixedly have two pin holes on the sliding sleeve.

First section wing and second section wing can be deployed in a plane because of the fixing slip of sliding sleeve is connected in use easily, foldingly when non-working condition make it to stick together and have shortened length, are very easy to and carry and store.

The specific embodiment

Referring to Fig. 1, the utility model comprises one first section wing 10 and one second section wing 20, links to each other by a bending joint 30 between this first section wing 10 and second section wing 20, and bending joint 30 is a biaxial hinge, is a prior art.The two ends in bending joint 30 respectively with an end of this first section wing 10 and second section wing 20 be fixedly linked (being to fix in the present embodiment) in the riveted joint mode, have on first section wing 10 and launch that its quantity is 2 in this enforcement of the fixed orifice 100(profit), have on second section wing 20 that its quantity is 2 in folding this enforcement of the fixed orifice 200(profit), one fixedly sliding sleeve 40 have with first, two

sections wings

10,20 sections that match, it is enclosed within bending joint 30 and first slidably, two sections wings 10, restriction bending joint 30 bendings on 20 the lateral surface, or slide into and allow bending joint 30 expose and can bend on second section wing 20, have on the sliding sleeve 40 fixedly that its quantity is 2 in this enforcement of the pin hole 400(profit), pin hole 400 optionally aligns and launches fixed orifice 100 and folding fixed orifice 200, and is 2 with its quantity in this enforcement of the latch 401(profit respectively) insert and fix.

Cooperation is referring to Fig. 2 to Fig. 4, when rotor uses, first section wing 10 and second section wing 20 are launched to be a straight line according to bending joint 30, sliding fixedly, sliding sleeve 40 to pin hole 400 alignment launch fixed orifice 100 positions, and with in latch 401 insertion pin holes 400 and the expansion fixed orifice 100, make bending joint 30 be set in fixedly in the sliding sleeve 40, first section wing 10 and second section wing 20 sliding sleeve 40 that is fixed is fixed in the plane, becomes single-piece rotor shown in Fig. 2; In the time rotor will being folded, the latch 401 of deployed condition shown in Fig. 2 is extracted, sliding fixedly, sliding sleeve 40 to pin hole 400 alignment fold fixed orifice 200 positions, and with in latch 401 insertion pin holes 400 and the folding fixed orifice 200, even so the bending joint 30 between the section of the winning wing 10 and the second section wing 20 is exposed and can be folded, promptly as shown in Fig. 3 to Fig. 4, first section wing 10 can bend downwards, sticks together with second section wing 20 for it.

First section wing 10 and second section wing 20 can launch to be connected a plane in use easily, and slide into by fixing sliding sleeve 40 and to entangle this bending joint 30 and this first and

second section wing

10,20 lateral surface restriction bending joint 30 bendings, allow bending joint 30 expose and can bend on second section wing 20 and in the time will collecting, fixing sliding sleeve 40 can be slid into, so can be with first and

second section wing

10,20 folding make it to abut in together, are very easy to and carry and store.
