Abstract

The utility model relates to a driving mechanism for changing the picture on an advertising casing. The mechanism is controlled by a micro motor, and after reducing speed through a group of reduction gears, two bevel gears separately drive two parallel long shafts to rotate. Each long shaft is respectively provided with a plurality of bevel gears, and each bevel gear drives an advertisement display board of triangle body shape respectively through a short shaft. The advertisement display board on the first long shaft can compose a picture, and the advertisement display board on the second long shaft can compose another picture at the same time. Namely, at the same time two pictures can be presented for people, and the pictures are caused to rotate in a certain time interval to make the advertising casing body present six pictures.

Description

Driving mechanism for changing picture on advertizing casing

The utility model relates to a kind of mechanical transmission mechanism that is used for advertisement casing conversion advertisement picture.

Along with development of market economy, advertisement has become hotel, shop or enterprise and has propagated characteristic or the requisite weapon of product of oneself to people, particularly in a hotel or the people of restaurant can utilize extension advertisement casing on the wall, just the characteristic that can introduce oneself to the pedestrian plays propaganda function.And present this extension casing advertisement cabinet on the wall can only design certain picture and font regularly, the interior pattern of perhaps drawing that generally can only former and later two directions allows the pedestrian see to write on the advertisement casing, have only two pictures, so promptly can not write out more and introduce content, simultaneously seem very stiff again, lack angry.

The utility model purpose provides a kind of mechanical transmission mechanism that is used on the advertisement cabinet, by this gear train the picture on the advertisement cabinet can be rotated within a certain period of time, can increase the content of introducing on the advertisement cabinet, a plurality of pictures occur.

The utility model is by the minitype motor driving gear, gear drives worm screw again, worm screw drives worm gear again and rotates, by one group of bevel gear two major axis that are parallel to each other are rotated at last, on two parallel major axis, several bevel gears all are housed respectively on the every major axis, and drive the billboard that is the triangle body shape, these billboards all rotate to a direction, and the billboard that rotates of controlling is formed a picture each other jointly on the every major axis.The triangle body shape billboard that drives on such major axis can present three pictures, and two major axis present six pictures altogether, and the inner conversion at certain time intervals of each picture.

Below in conjunction with Fig. 1, Fig. 2 elaborates the utility model theory structure: at first rotated by axle 3 driven gears 6 by micromachine D, gear 6 and gear 7 engagements, and driven gear 7 rotates, gear 7 is contained on the scroll bar 4, scroll bar 4 is rotated, minor axis 5 by bearing fixing on casing, on minor axis 5 and turbine 8 and bevel pinion 9 be housed, scroll bar 4 drives turbine 8 and rotates, bevel pinion 9 makes the bevel gear wheel 10 that is engaged with rotate again simultaneously, bevel gear wheel 10 rotates bevel gear 12 by little axle 11, and bevel pinion 13 and bevel pinion 14 are housed on major axis 1, bevel gear 15, major axis 1 are by bearing 16,17 are fixed on the casing.Bevel pinion 13 and 14 drives bevel gear 18 and 19 respectively and rotates, and they rotate the display board that is the

triangle body shape

22,23 that links to each other separately by

little axle

20 and 21 respectively again; Meanwhile, bevel gear 15 also drives bevel gear 24 and rotates, bevel gear 24 drives bevel gear 26 by axle 25 and rotates,

bevel gear

29,30 and 31 is installed on major axis 2, major axis 2 is fixed on the casing by bearing 27,28, the rotation of bevel gear 26 is rotated the bevel gear 29 that is engaged with, and the

bevel gear

30 and 31 on major axis 2 is rotated thereupon simultaneously.

Bevel gear

30 and 31 drives the bevel gear 32 and 33 that is engaged with respectively and rotates, and they rotate the display board that is the

triangle body shape

36,37 that drives separately again respectively by little axle 34 and 35.The bevel pinion 13,14 that is installed on the major axis 1 will be with original tooth 2/3 flush away, the rotating speed of micromotor is slowed down by series of gears after, picture is stayed for some time rotates again.Can how much increase several conelet gears 14 and

bevel pinion

30,31 on the axle separately according to the size and the displaying contents of casing on major axis 1 and the major axis 2.

The utlity model has to make and present the double-sided display picture on the advertisement cabinet, and at certain time intervals, can make the picture conversion again.The utility model has remedied the deficiency of existing advertisement cabinet, makes the better effect of application performance of advertisement cabinet.

Fig. 1 is the utility model structure principle chart

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 turbine, scroll bar and two major axis, and two major axis are installed in parallel on the casing, and casing is assembled by transparent material.The light fixture of daylight lamp or other type is housed in case, and picture displayed also can allow the pedestrian see at night on the advertisement casing so that make.The display board that is the triangle body shape is an equilateral triangle body shape, and the plane on each limit and other plane on both sides are bondd mutually by transparent material.The utility model can be by day, 6 group of pictures appear in night allows the pedestrian see, promptly can control three group of pictures on every major axis.
