Three-side rotating advertising light box

Abstract

The invention relates to a three-side rotating advertising light box. The box comprises a box body frame with at least three sides, wherein a rotatable intermediate shaft is arranged in the box body frame; a reflecting plate is arranged on the intermediate shaft; and a lamp tube is fixed on the reflecting plate. The box is characterized in that: at least three magnets corresponding to one another are distributed at the peripheries of two ends of the intermediate shaft; an included angle between central axes of every two of the at least three magnets corresponds to the rotation angles of the three sides of the box body frame one to one; the number of the magnets is the same as that of magnets on the box body frame; a driving magnet is fixedly arranged on the intermediate shaft; and the driving magnet and any one of the three magnets positioned at two ends of the intermediate shaft are positioned on the same horizontal line when the driving magnet is in a static state. The three sides or two sides of the box body frame are turned by a magnetic element, the magnetic element has lighter weight and lower manufacturing cost than other driving parts, the sides can be easily poked and turned by hands, different pictures are displayed in time, and one side can be displayed in a still mode.

Description

technical field [0001] The invention relates to an advertising light box, in particular to an advertising light box that can be rotated on three sides. Background technique [0002] Existing large-scale outdoor multi-screen display light boxes are mostly driven by a motor, and then the speed is limited by a reducer to rotate the box or scroll the single light box. Can not display multiple pictures at the same time, not suitable for multi-variety catering industry. The main parts of the existing three-sided (or two-sided) flip light boxes are cast aluminum parts or extruded aluminum profiles. The quality of a single light box is heavy, and if multiple groups are used, it will be even heavier, which will cause inconvenience to assembly, transportation and installation. .

Cannot display multiple pictures at the same time, not suitable for multi-variety catering industry

The main parts of the existing three-sided (or two-sided) flip light boxes are cast aluminum parts or extruded aluminum profiles. The quality of a single light box is heavy, and if multiple groups are used, it will be even heavier, which will cause inconvenience to assembly, transportation and installation.

[0003] The rotating body of the turntable on the box frame relative to the fixed disk on the frame support shaft is a sliding body (equivalent to a sliding bearing), which has large friction force and large turning resistance, and is all precision cast zinc parts, and its weight is heavy and the production cost is high.

The connection between the left and right side sealing plates of the box frame and the upper and lower connecting rods is fastened with nine self-tapping screws on each side, which is easy to loosen and can only be assembled at one time. There is no positioning reference for the assembly of the side sealing plates and connecting rods, which affects the assembly accuracy , affect the appearance quality

At the same time, the cantilever frame used for installation and fixing is not suitable for hanging on the ceiling, but only suitable for installation on the wall
