Abstract

The invention discloses a supporting device for a billboard. The supporting device comprises a display table, a base, an inflating pump, a first turbine, a second turbine and a negative pressure vane.The inner bottom wall of the base is vertically connected with a first rotating shaft. The top of the first rotating shaft is fixedly connected with the bottom of the display table. The first turbineis located in the base and fixed to the first rotating shaft. The inflating end of the inflating pump communicates with a cavity of the base. The base is provided with a sleeve. The display table islocated in the sleeve. The two sides of the sleeve are provided with outer layer openings correspondingly. A pipeline communicates with the position between the base and one of the outer layer openings. A plurality of inner layer openings are formed in the circumferential direction of the display table. The display table is internally provided with a sealing piece. The sealing piece is rotationally connected with a second rotating shaft. The end, close to the sleeve, of the second rotating shaft is connected with the second turbine. The other end of the second rotating shaft is connected withthe negative pressure vane. The display table is provided with a plurality of adsorption holes. The upper end surface of the display table is provided with a plurality of exhaust holes. Thus the problem that an advertising cloth is prone to loosening and falling off when fixed to the billboard is solved.

Description

technical field [0001] The invention relates to the field of billboards, in particular to a supporting device for billboards.
