Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

With reference to the accompanying drawings shown in 1-5, a kind of turnable folding guardrail of the utility model, applied to the outer of flight simulator In portion's structure, mainly include metope 1, upper pedal 2, bar 1, bar 24, bar 35.

Wherein, upper pedal 2 is horizontally disposed with and passes through metope 1 and is fixed.

Bar 1, bar 24, bar 35 are sequentially connected from bottom to up.One end of bar 1 is fixed on metope 1 by the first hinge 6 On, the other end of bar 1 is connected by the second hinge 7 with one end of bar 24, and the other end of bar 24 passes through tri-joint mechanism 8 and bar 35 one end connection.The other end of bar 35 is fixed on by bearing block 9 on upper pedal 2.Above-mentioned connection, fixed structure, it is each to cut with scissors Point position has shifting fork structure, and the shift fork female of each shifting fork structure is equipped with universal bearing, deep-groove ball axis is equipped at bearing block 9 Hold, can ensure bar 1, bar 24, bar 35 both ends can be with flexible rotating.

On upper pedal 2, upper limit seat 10 and lower limit seat 11 are respectively arranged in the both sides of bearing block 9, is respectively used to work as /V is carried out to bar 35 when guardrail is opened or folded.

In addition, 13 and second fixed structure 14 of first fixed structure is respectively equipped on bar 1, bar 24, for being beaten in guardrail It opens or when stowed position fixes guardrail.Such as it will hingedly be tied by 13 or/and second fixed structure 14 of first fixed structure Structure locks, so that the opening of guardrail or collapse state are stablized.The position of 13 and second fixed structure 14 of first fixed structure It puts and is not limited to shown in attached drawing 1, those skilled in the art can be disposed at bar 1, bar 24, any position on bar 35. 13 and second fixed structure 14 of first fixed structure can be the ring or hole passed through for bolt etc., when guardrail is opened or is received When closing in place, guardrail is fixed on using the first fixed structure 13, the second fixed structure 14 and bolt (or nut) It repairs on cat ladder or metope 1.

As a preferred embodiment, two handrail 12 of bar is additionally provided on bar 24.

The operation principle of the utility model is briefly described as follows.

When firmly drive rod 24 (or two handrail 12 of bar), bar 35 will be rotated around 9 place axis of bearing block, while bar one 3 will rotate around 6 place axis of the first hinge.

When upwards firmly, when the restriction site of the system motion that bar 1, bar 24, bar 35 form to upper limit seat 10, Guardrail is i.e. into working condition, and the state of bar 24 is just parallel with repair cat ladder at this time, need to first with bolt or nut or other Means are securely solid by bar 1, bar 24, bar 35 and repair cat ladder by the first location structure 13 or/and the second location structure 14 Fixed, which may act as repair cat ladder handrail, as shown in Figure 2, Figure 4 shows.

When downwards firmly, when the restriction site of the system motion that bar 1, bar 24, bar 35 form to lower limit seat 11, Guardrail is in off working state, is tied using bolt or nut or other means by the first location structure 13 or/and the second positioning Bar 1, bar 24, bar 35 and metope 1 are fixedly secured by structure 14, ensure that guard bar structure will not when a whole set of flight simulator moves The noises such as percussion are generated because of vibrations, as shown in Figure 3.
