Title:
SELF-RESTORING ANTI-COLLISION STAND COLUMN
Document Type and Number:
WIPO Patent Application WO/2023/173468
Kind Code:
A1
Abstract:
A self-restoring anti-collision stand column (6), comprising a flange mounting base (1), a supporting pipe (2), elastic energy absorption blocks (5), and an anti-collision pipe (4). The center of the flange mounting base (1) protrudes to form a fixing portion; the supporting pipe (2) is fixed to the fixing portion; the anti-collision pipe (4) is sleeved outside the supporting pipe (2); the bottom of the anti-collision pipe (4) is closely attached to the flange mounting base (1); the inner diameter of a middle section of the anti-collision pipe (4) shrinks to form a step face; and a plurality of elastic energy absorption blocks (5) are provided between the anti-collision pipe (4) and the supporting pipe (2), and the elastic energy absorption blocks (5) are disposed on the step face. When the anti-collision column (6) is collided, the anti-collision pipe (4) is deflected under force, so that the elastic energy absorption blocks (5) are compressed to absorb collision energy, and damage of the collision to the anti-collision column (6) is avoided; and after the collision is finished, external force acting on the anti-collision column (6) disappears, the elastic energy absorption blocks (5) release elastic potential energy, and the anti-collision column (6) automatically returns to be in a standing state in cooperation with a limiting function of the step face in the anti-collision pipe (4). The damage of the collision to the anti-collision column (6) is reduced by means of cushioning, and the protective effect of the anti-collision column (6) is effectively improved.
