摘要： An elastic bollard for rack protection is installed in front of a rack structure to effectively buffer external shock and prevent damage to a rack structure, so that when a shock is applied from multiple directions to a vertical pole installed upright on the ground, the vertical pole tilts in the direction in which the external force is applied, and since the elastic part is installed inside, the vertical pole tilts in the direction of application of the external force, and simultaneously can be restored to its original upright state due to the elastic force, thereby making it possible to more effectively absorb and alleviate shock, and furthermore, since the case part itself is equipped with an elastic buffer part, it is possible to maximize a shock alleviation effect.
