Description

A telescopic and folding portable operating platform

technical field

The invention relates to the field of a mobile operation platform, in particular to a telescopic and foldable portable operation platform; it is suitable for daily maintenance of larger equipment in construction sites and factories, building decoration, indoor or outdoor maintenance, and the like.

Background technique

Workbenches used in existing buildings, decorations and homes, that is, support frames for construction or users to work at a higher position with the help of workbenches, usually use scaffolding or movable scaffolding; even for convenience, a few pieces of wood are used Easy to build the console. However, there are deficiencies in these methods. For example, although a ladder can make the height of the workbench meet the construction requirements, its structure is loose and unstable, and the center of gravity is easy to change with the movement of the people on the workbench, which can easily cause shaking and falling injuries of the construction workers on the workbench. Moreover, in order to meet the height requirement of the ladder, the length of the tripod will inevitably be increased, making the ladder structure seem long and heavy, which is very inconvenient to carry and place. Another example is the existing high stool. The foot frame and the workbench are fixedly connected in structure. It is wide, long and high in shape, which is not conducive to carrying and placing. This structure is usually only suitable for fixed construction. place and environment use.
