Description

Folding workbench

Technical Field

The utility model belongs to the technical field of workbenches, and in particular relates to a flip-folding workbench.

Background Art

Workbenches are quite practical in daily life and are usually used to support objects. They are commonly used in the decoration and construction processing industries. Workbenches generally include a table top body and a supporting tripod. The supporting tripod can rotate relative to the table top body, so as to facilitate the folding and unfolding of the table top body. However, there are often two supporting tripods under the existing table top body. Each time the table top body is unfolded, the two supporting tripods need to be rotated synchronously so that it can be unfolded smoothly. The operation is time-consuming and laborious. After the table top body is folded, the direction of the table top body needs to be rotated in order to pick up the table top body. Since the overall mass of the table top body and the supporting tripod is large and it is not convenient to flip it, it is inconvenient for users to carry and transfer it. Therefore, it is necessary to design a flip-folding workbench to overcome the above difficulties.
