Wind-resistant advertising board capable of being automatically rolled

Abstract

The invention discloses a wind-resistant advertising board capable of being automatically rolled. The wind-resistant advertising board comprises a base, a vertical column, an upper column tube, a lower column tube and advertising cloth, wherein the vertical column is provided with a sliding port used for lifting the upper column tube, one end of the advertising cloth is fixedly connected to the upper column tube, the other end of the advertising cloth is rolled into the lower column tube by a rolling mechanism; a user drives a series of devices to pull up the upper column tube in a hand-cranking mode, so that the advertising cloth is pulled out of the lower column tube and spread out; when wind force is too large, a wind measurement block on the vertical column is blown, a series of devices are linked, and the upper column tube slides downward due to the gravity and the action of the pulling force of the rolling mechanism rolling the advertising cloth, so that the advertising cloth isrolled into the lower column tube. The wind-resistant advertising board capable of being automatically rolled can roll the advertising cloth when the wind force is larger, the overall wind receiving area of the advertising board is reduced, the advertising board is prevented from being damaged or collapsing and hitting passing vehicles and pedestrians.

Description

technical field [0001] The invention relates to the field of service media, in particular to a wind-resistant billboard that can be automatically rolled up.
