Abstract

The invention relates to a vehicle-mounted folding and overturning ladder and a using method thereof. The ladder comprises a slideway assembly, a ladder frame assembly and a pedal assembly, wherein the slideway assembly and the ladder frame assembly are connected through a pin shaft, and the ladder frame assembly and the pedal assembly are connected through a rotating shaft; one end of the slideway assembly is fixedly connected with the chassis van body of a vehicle body, while the other end is free; supporting iron of which the cross section is an obtuse triangle is welded on the bottom surface of the free end; and a positioning lock is arranged on the supporting iron. When in use, the positioning lock is loosened to pull out the ladder frame assembly, and the pedal assembly is overturned. The ladder facilitates users to taking equipment in a van vehicle, has the advantages of simple structure and reasonable layout and is convenient to operate and maintain and suitable for being arranged on the van vehicle.

Description

technical field [0001] The invention relates to a vehicle-mounted auxiliary facility of a van vehicle and a method for using the same, in particular to a vehicle-mounted folding and turning ladder and a method for using the same. Background technique [0002] Vans often need to take and place objects or equipment from the box. The existing car body generally does not have a ladder. When you need to use it, you need to find the ladder outside the vehicle. It is time-consuming and laborious to use. To the ladder and cause unnecessary loss, meanwhile, adopt the ladder outside the car body, the setting up of the ladder is subject to the situation of the bottom surface, and the stability is poor when often used, and there is a potential safety hazard. Therefore, seeking a safe and simple vehicle-mounted ladder form has just become the place that the van needs to be improved urgently. Contents of the invention [0003] The purpose of the present invention is to provide a vehicl...
