Embodiment

Stair are generally located on the front portion or rear portion in compartment, and due to more one layer, carrying capacity is bigger than other cars.But Narrow stair in compartment, do not occupy the space of preciousness, and cause the inconvenience got on or off the bus in compartment, when vehicle is opened During row, if driver's emergency brake, the people on stair is also possible to fall down, and even causes serious damage.

Inventor is directed to above-mentioned technical problem, and by the analysis to reason, constantly research finds that a kind of double-layer public transport vehicle is used Staircase structure, it includes being built in stair, stair handrail in double-layer public transport vehicle, the stair handrail be two respectively with stair What is be adapted is installed on stair both sides, and each stair handrail is fixedly installed on stair by protective cradle and is located at stair both sides, The hand steered structure of stair activity is formed, the protective cradle includes more support bars and neonychium, wherein each support bar both ends point It is not fixedly linked with stair and stair handrail, and being fastened on support bar for neonychium card dismounting, form the protection of stair both sides Structure.

Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.

Embodiment：

As shown in figure 1, a kind of technical scheme of double-layer public transport vehicle staircase structure, it includes being built in double-layer public transport vehicle Stair 1, stair handrail 2, the stair handrail 2 be two be adapted respectively with stair 1 be installed on the both sides of stair 1, each building Terraced handrail 2 is fixedly installed on stair 1 by protective cradle and is located at the both sides of stair 1, forms the hand steered structure of stair activity 1. To save the area in double-deck public transport, and then the narrower in width of the stair 1, can only allow two people and meanwhile lean to one side by, in order to Ensure height, so as to cause the gradient of stair big, the height of each step is higher in stair, if such structure coordinates garage Sailing inertia or acceleration, deceleration operation can cause passenger to rush on stair to fall, even result in serious personal injury.

Improved so as to which this is new in the structure of support stair handrail 2, and then form described protective cradle itself and stair Both sides are effectively protected, injury caused by so as to prevent from reducing adult in collision process, the children that also mode was fallen, limb Body is sandwiched in the gap between support bar.Further increase the security of stair in double-layer public transport vehicle.

As shown in Figures 1 to 4, foregoing protective cradle includes more support bars 3 and neonychium 4, wherein the both ends of each support bar 3 It is fixedly linked respectively with stair 1 and stair handrail 2, and being fastened on support bar 3 for the card dismounting of neonychium 4, form stair both sides Protection structure.The rear side of neonychium 4 is fixed on support bar 3 by snap ring 5 and is connected, and is additionally provided with the snap ring 5 in branch The location structure that strut 3 coordinates, the location structure includes grafting projection 6 and grafting groove 7, the grafting projection 6 are placed in card On the madial wall of ring 5, and grafting groove 7 is opened in the corresponding inner side of support bar 3, and the grafting projection 6 coordinates in grafting groove 7 Realize positioning.

Preferably：The neonychium 4 is the Soft Roll pad for being built-in with damping sponge.Specifically：The neonychium 4 includes one Hard backing plate, and the damping sponge is placed on hard backing plate, and a damping film is additionally provided with above damping sponge, outermost layer It is enclosed with a PU layers.

Specifically：As shown in Figures 1 to 4, the quantity of the support bar 3 is typically consistent with the quantity of stairway step, And then the quantity of snap ring 5 at the rear of neonychium 4 can be 3-5, the corresponding support bar 3 of each snap ring 5 is set, in the snap ring 5 Grafting projection 6 is inserted into grafting groove 7, and grafting projection 6 is section cylinder in T shape, and its outer end diameter is big, and right The grafting groove 7 answered includes circular hole and bar hole, and affiliated bore inner diameter is adapted in the raised end of grafting, and the width of bar hole Degree is adapted with grafting projection external diameter smaller part, and then grafting projection can be effectively inserted into grafting groove 7, each snap ring energy holding In on corresponding support bar 3, radially extension forms two connection walls for the openend both sides of each snap ring 5, distinguishes in two connection walls The through hole being adapted is offered, formation can allow the structure that bolt passes through, and the bolt can cooperatively form fixing clasp with nut Structure.
