Description

Technical Field

[0001] The utility model relates to the technical field of single cantilevers, in particular to a single cantilever with a self-supporting structure. Background Art

[0002] One end of the single cantilever is a fixed support that does not produce axial, vertical displacement and rotation, and the other end is generally a free end. In many occasions, the single cantilever plays a supporting and lifting role, especially when it is used to support highway signs beside the highway, it usually provides long-term support.

[0003] In order to facilitate the replacement of highway signs, many designs design the single cantilever as a liftable structure. In order to better ensure the stability of the single cantilever, an inclined support structure is added under the single cantilever. After the single cantilever is lowered, this type of support structure will still affect the lowering height of the single cantilever due to its own height, making it very inconvenient to replace the sign.

[0004] Therefore, it is necessary to design a single cantilever with a self-supporting structure. Utility Model Content
