Owing to also be provided with guiding mechanism on the rail plate, the direction the during push-and-pull of the ladder that can guarantee to get on the bus can not be offset, and guiding mechanism is provided with pulley in addition, operated when further having guaranteed to get on the bus terraced push-and-pull smooth and easy;
Because every grade of step all is equipped with the diamond plate of aluminium alloys, can play anti-skidding effect.
Because described backplate support adopts thick square tube or the rectangular tube of 4mm, be enough to bear the above weight of 200Kg, at secure context further guarantee has been arranged also.
Because the working platform arranged outside has foldable spring handle, be convenient to the push-and-pull of the whole plug-type ladder of getting on the bus, handle has enough intensity can guarantee that ladder is advanced freely to pull out in addition, does not take the space outerpace of vehicle after folding;
Owing at least two spring snap-ons have been installed in the working platform outside, thereby after ladder pushes in, the monolithic ladder of getting on the bus is fixed with vehicle body, reached spacing purpose by the spring snap-on, and the ladder that guarantees to get on the bus can not skid off in the vehicle traveling process, has ensured safe in utilization
Because the outward flange of platform can install guardrail additional, thereby has guaranteed staff's safety.。

Number description:
Trapped orbit 1, rail plate 2, working platform 3, backplate support 4, get on the bus ladder outer shrouding 5, the step 6 of getting on the bus, stopping means 7, pulley 8, bearing 9, guiding mechanism 10, pulley 11, spring snap-on 12, link up with 13, spring assembly 14, buckle 15, spring handle 16.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises the step 6 of getting on the bus, working platform 3, backplate support 4, get on the bus the ladder outer shrouding 5, rail plate 2 and trapped orbit 1, the described step 6 of getting on the bus is connected with described working platform 3, described backplate frame 4 is the integral body that welds together with the framework of working platform 3, the described outer shrouding 5 of ladder of getting on the bus is installed on the described backplate support 4, bearing 9 is installed in the described rail plate 2 and is arranged at described working platform 3 two ends, described trapped orbit 1 be provided with stopping means 7 and with described rail plate 2 with match, described stopping means 7 is provided with pulley 8;
