CN2300155Y - Device for making picture on advertising box rotate - Google Patents

Abstract

The utility model relates to a device for rotating a picture on an advertising box, particularly a device which is controlled by a micro-motor. The speed of the device for rotating a picture on an advertising box is reduced through a set of speed reducing gears, and a long shaft is driven by gears to rotate. Two gears are arranged on both ends of the long shaft, and each gear is engaged with a driving sprocket respectively. The driving sprocket enables the driven sprocket to rotate through a transmission belt, and then the picture on the advertising box is rotated through the functions of an aligning rolling cylinder and a rolling cylinder. The utility model has simple structure and low cost.

Description

A kind of device that picture on the advertisement cabinet is rotated

The utility model relates to a kind of mechanical driving device that the advertisement casing constantly rotates advertisement picture that is used for.

Along with development of market economy, advertisement has become hotel, shop, enterprise and has propagated characteristic or the requisite weapon of product of oneself to people, particularly in the hotel or the shop in front of the door the operator can utilize the advertisement casing to commodity and characteristic that the pedestrian introduces oneself, play advertisement function.But present this advertisement casing can only picture of fixed static, at most can only former and later two directions allow the pedestrian see content on the advertisement casing, have only two pictures, more contents is propagated on advertisement cabinet, simultaneously seem very stiff again, lack angry.

The purpose of this utility model is to propose a kind of mechanical driving device that is used on the advertisement cabinet, by this device the picture on the advertisement cabinet can constantly be rotated, and a plurality of pictures occur, increases to introduce content, active atmosphere on the advertisement cabinet.

The purpose of this utility model is achieved in that by the minitype motor driving gear, gear drives worm screw again, worm screw drives worm gear again and rotates, and a major axis is arranged on worm gear, and the major axis two ends respectively have a bevel gear respectively, mesh with drive sprocket respectively, the drive drive sprocket rotates, and at the parallel correspondence position of drive sprocket two driven sprockets is arranged, and drive sprocket and driven sprocket respectively account for position, an angle of square, form quadrilateral, in one plane.A levelling cylinder is arranged in the middle of drive sprocket, be equipped with three filter cylinders, form little triangle in the quadrilateral interposition, around drive sprocket, driven sprocket and levelling cylinder, reaching three cylinders has a driving-belt, when motor driven gear rotates, by gear drive, drive sprocket rotates, and driving-belt will drive driven sprocket and levelling cylinder, and other three cylinders rotate, the picture of being made up of some width of cloth also can rotate thereupon, promptly can form some advertisement pictures.Elaborate structure of the present utility model below in conjunction with accompanying drawing: at first rotate by axle 1 driven gear 2 by micromachine D, gear 2 and gear 4 engagements, and driven gear 4 rotates, gear 4 is contained on the worm screw 3, worm screw 3 is rotated, minor axis 5 by bearing fixing on casing, worm gear 6 and two bevel gears 7 are housed on minor axis 5,8, worm screw 3 drives worm gear 6 and rotates, make and bevel gear 7, the drive sprocket 9 of 8 engagements, 10 also rotate, drive driven sprocket 11 by driving- belt 17,12 rotate, and also make levelling cylinder 13 and cylinder 14 simultaneously, 15,16 rotate, thereby make the picture that is centered around the driving-belt working direction in continuous rotation.

The utility model can make that picture constantly rotates on the advertisement cabinet, also can stop within a certain period of time by Electric Machine Control, makes picture still motionless.The utility model has remedied the deficiency that exists on the existing advertisement cabinet, makes advertisement cabinet can bring into play better effect.

Fig. 1 is the utility model principle assumption diagram

Embodiment: adopt the 370W micromachine, the alternating current 220V operating voltage; Motor speed is at 1450 rev/mins, and a series of bevel gear and worm gear, worm screw and major axis, and two drive sprockets and two driven sprockets are installed in parallel on four angles of casing, and casing is assembled by transparent material.The light fixture of daylight lamp or other type is housed in case, makes that picture displayed also can allow the pedestrian see at night on the advertisement casing.
