Vehicle overturning step ladder platform

Abstract

The invention discloses a vehicle overturning step ladder platform, which comprises an upper pedal, a lower pedal, limiting rod combinations arranged in pairs, air springs, connecting rods and storagelocking devices, wherein one corners of the two ends of the upper pedal are hinged to the upper ends of straight rods on the two sides of a vehicle side cabin frame respectively, and one corners of the two ends of the lower pedal are hinged to the lower ends of straight rods on the two sides of the vehicle side cabin frame respectively; one ends of the air springs are hinged to the middle parts of the two ends of the upper pedal, and the other ends are respectively hinged with the other corners of the two ends of the lower pedal; one ends of the limiting rods are hinged to the middle parts ofthe two ends of the upper pedal, and the other ends are respectively hinged with the middle parts of the two ends of the lower pedal; one ends of the connecting rods are hinged to one corners, away from the hinging seat, of the two ends of the upper pedal, and the other ends are respectively hinged with the middle parts of the two ends of the lower pedal; and the storage locking devices are arranged at the positions, away from the hinging rod, of the two sides of the vehicle side cabin frame and the two ends of the lower pedal. The vehicle overturning step ladder platform is compact in structure and labor-saving and convenient to use, expands the application range and improves the operation efficiency.

Description

technical field [0001] The invention relates to a vehicle-mounted step ladder, in particular to a step ladder platform which is arranged in a side compartment of a vehicle and can be opened by turning 90° clockwise or closed by turning 90° counterclockwise, and belongs to the technical field of vehicle accessories. Background technique [0002] The square cabin or van can be used for field operations and combat, and is a special equipment used in geological exploration, communication engineering, water conservancy engineering, construction engineering and military fields. The equipment or instruments installed in the square cabin or van sometimes need to be pulled out of the cabin For operations, it is necessary to set up a retractable platform on the side of the shelter or van to support the equipment or instruments that work outside the cabin. inner space. In addition, although the existing boarding ladder can be folded and stored in the cabin, it also has the problem of ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defect that the existing square cabin or the working platform of the van or the boarding ladder occupies a relatively large space in the cabin after being stored, the present invention provides a vehicle reversing step platform, which reduces the space occupied by the step platform. space
