The specific embodiment
Shown in Fig. 1,2,3,4, the structure of door ladder is made up of terraced leg 1, support axle 2, pedal 3, and pedal 3 is a dull and stereotyped plate body, be provided with beam barrel 4 at the two ends of pedal 3, the other two ends of pedal 3 are provided with vertical flanging 5, and the termination of the two ends of flanging 5 and beam barrel 4 is fixedly linked, and increases the intensity of pedal 3 with this; Insert support axle 2 in beam barrel 4, the two ends of support axle 2 are vertically fixed on two terraced legs 1, can rotate flexibly between pedal 3 and the support axle 2, have so just given the parallelogram sturcutre of door ladder, make it have folding alerting ability.Be provided with one section at an end of terraced leg 1 and support 6, increase the distance in terraced leg 1 and compartment with this; Be provided with roller 7 at the other end that supports 6, the axle of roller 7 is fixed on and supports on 6, and roller 7 is born the upper load of a ladder; Roller 7 is placed in the roller groove 8, and can be up and down in groove, and roller groove 8 opposite house ladders up and down plays the guide securement effect; The cross-sectional plane of roller groove 8 is the C type, and the outside of roller groove 8 is fixed on the both sides of doorframe 9, and roller groove 8 lower ends are with dull and stereotyped 10 shutting the lower end of doorframe (promptly).Outer lower portion at terraced leg 1 is provided with bayonet socket 11, bayonet socket 11 be shaped as the outside C shape of opening, be made by elastic plate, the column 12 of handrail can bang in the bayonet socket 11, fixes the position of the column 12 of handrail with this.Be provided with gib head 14 below dead point pawl 13, the door ladder that 14 pairs of gib heads are packed up plays fixation.
The basic configuration of handrail is a parallelogram lever, and structure is by column 12, last handrail beam 15, handrail beam 16 and perpendicular support 17 composition that is connected as a body down.Be provided with hinge 18 on box type column on the handrail 12, an end of hinge 18 is fixed on the intermediate board body 19 of side in compartment, and the other end is fixed on the column 12, and handrail and compartment are connected as a single entity; Handrail can left-right rotation under the effect of hinge 18, on the side plate that is fitted in the compartment, on the lower body 20 of side plate, be provided with locator card 21, locator card 21 be shaped as the outside C shape of opening, be made by elastic plate, the column 12 of handrail can bang in the locator card 21, and the effect of locator card 21 is to block the handrail that is attached on the side plate it can not swung in vehicle '.
