Lamp post billboard supporting device

Abstract

The invention aims to provide a billboard supporting device arranged on a lamp post. The device comprises a billboard body, a fixing strip, a spring, a bag-type billboard and the like, wherein a connection device of a foldable billboard structure of the billboard body is connected with a shedding device of a ]-shaped clamp so as to rotate by using a shaft pin; the fixing strip is used for fixing the ]-shaped clamp to the lamp post; the spring is used for connecting the connection device of the billboard body and the fixing strip; and the bag-type billboard is sleeved on the billboard structure. The billboard body is safely supported by the ]-shaped clamp; and because the friction area among various materials is small, the generated noise is low. The spring which is used for connecting the billboard body and the fixing strip can properly absorb an air pressure borne by the bag-type billboard sleeved on the billboard structure so as to prevent the billboard body or the lamp post from being damaged. Simultaneously an inside component of the billboard structure is connected with an upside component, an outside component and a downside component through hinges in turn; and when the billboard is not used, the upside component, the outside component and the downside component can be closed on the inside component, which not only prevents the appearance of a street lamp from being affected, but also ensures the safety of vehicles and pedestrians.

Description

technical field [0001] The invention relates to a billboard support device installed on a street light pole. Background technique [0002] In general, billboards that can effectively deal with wind pressure have been mentioned in my patent No. 178852 (Korean Patent), the specific content is that through the clamps fixed on the street light poles and the signboard clamps, after the guide rods are engaged, the Rotation, the gripper and the kanban gripper are connected by a spring, and rotate within an appropriate rotation radius according to the wind pressure strength, which can effectively withstand the wind pressure. However, because the holder and the kanban holder are connected by the guide rod, the problem of weak support force of the kanban is caused. It is also found that the structure is complicated and difficult to manufacture, etc., especially the friction area between the materials is large, noise and Elasticity issues. SUMMARY OF THE INVENTION [0003] In order...
