Description

Technical Field

[0001] This utility model relates to the field of vehicle pillar box technology, specifically to a lifting pillar box assembly. Background Technology

[0002] With the development and progress of the logistics industry, box trucks and box semi-trailers have been used and popularized more and more widely. For lift box trucks, each vehicle will be equipped with 4 sets of lift pillar box assemblies, and the lift pillar box assemblies are symmetrically arranged in pairs, which can provide support while installing the lifting mechanism.

[0003] However, in the existing technology, the lifting column box assembly only provides a lifting space for the lifting mechanism, but does not provide sliding limit for the lifting mechanism, resulting in insufficient structural stability during use. Furthermore, the connection between the overall structure of the lifting column box assembly and the bottom of the carriage is not secure enough, making it prone to shaking. In addition, the cylinder base is directly installed at the bottom of the lifting column box assembly without any positional limitation, which is also prone to shaking and has poor structural stability. The pins for installing the box door on the lifting column box are installed through bushings, but existing bushings are usually directly installed on the back plate and outer ring plate of the column box, which is not secure enough and prone to displacement, causing jamming when the box door opens or closes, affecting normal use.
