Abstract

The time-regulating type rotating plate billboard belongs to a novel movable billboard capable of regulating the time of rotating plate. The appearance is as follows: the suspension type is a rectangle with a certain thickness, and the field type is a triangle strip shape. The front surface of the rotary plate cylinder is provided with a plurality of regular triangle long cylinder-shaped rotary plate cylinders, and a rotary plate cylinder chain wheel is arranged on a head shaft of each rotary plate cylinder. The worm reducer linked by a motor drives a four-groove sheave mechanism, sheaves are connected with a driving sprocket through a shaft, the driving sprocket is used for connecting all the rotating plate barrel sprockets in an S shape through a chain, when the gear ratio of the driving sprocket to the rotating plate barrel sprockets is made to be 4: 3, the four-groove sheaves rotate for 90 degrees once, the driven rotating plate barrel rotates for 120 degrees, and one surface of the rotating plate barrel is changed to form a second advertising plane. A travel switch and a time relay are arranged on a power line, a contact is arranged on a thumb wheel of a sheave mechanism, the thumb wheel toggles the sheave once and then touches the travel switch to cut off the power, and the time relay is electrified within a time adjusted according to needs to enable a motor to run.

Description

Time regulated rotary plate ad board

The utility model belongs to a kind of walking advertisement board novel, that the time can be regulated.

The billboard of being made by advertising company mostly is immotile at present, is difficult to the purpose that reaches novel eye-catching.And see flap billboard (as the flap billboard on limit, TV Italy first class league football match court) in person because rotating speed is too fast, and spectators can only see advertised name or catch-phrase and so on, the time does not allow to propagate concrete product content, is a big defective.

The purpose of this utility model is to provide a kind of three ad contents are constantly changed, and scalable is changed the flap billboard of time as required, to adapt to the needs of various different advertisements.

Now in conjunction with the accompanying drawings the utility model principle is described:

Fig. 1 is a suspension type time regulated type flap billboard external form.

Fig. 2 is a place formula time regulated type flap billboard external form.

Fig. 3 is time regulated type flap advertisement board structure and principle of work.

Among the figure: 1-motor 2-worm reducer 3-Geneva mechanism

4-drive sprocket 5-flap tube sprocket wheel 6-chain

7-flap tube 8-travel switch 9-time relay 10-shell

The shell 10 of time regulated type flap billboard is to use the angle steel welded framework as shown in Figure 1 and Figure 2, and the slot that flap tube 7 is installed is left in the front, is equipped with a plurality of flap tubes 7 in the hole side by side, and other several times are sealed with iron plate or other plate.Suspension type (Fig. 1) profile is to have certain thickness rectangle (thickness is that try one's best under the rotary machine prerequisite thin can be installed) can be suspended on indoor, outdoor.Place formula (Fig. 2) is to make the triangularity strip, is convenient to ground on the scene and puts surely.Flap tube 7 is the long tubes of equilateral triangle, long tube equilateral triangle center, two ends respectively has one, be equipped with flap tube sprocket wheel 5 on the one end axle, flap tube 7 and horizontal row are contained in the slot, its installation dimension is: adding certain interval with the flap tube equilateral triangle length of side is distance, be installed in side by side on the same axis, the distance on axis and limit, hole is the vertical range of equilateral triangle center to the equilateral triangle limit, like this, the one side of all flap tubes 7 be transferred to the limit, hole at ordinary times, whole billboard front has just become a plane, and we cry its advertisement plane.If with chain 6 all flap tube sprocket wheel 5 and drive sprocket 4 are associated in a time-out, all flap tubes 7 also can rotate synchronously when drive sprocket 4 rotated.Will change one side when all flap tubes 7 rotate 120 ° and form second advertising plane, will form the 3rd advertisement plane when rotating 120 ° again, go round and begin again, will reach the purpose of constantly changing three ad contents.

The purpose of this utility model realizes in the following manner.It is to slow down by motor 1, interlock worm reducer 2, and it is coaxial with the thumb wheel of Geneva mechanism 3 to drive four groove Geneva mechanism 3(worm gears again) sheave is coaxial with drive sprocket 4 again.It is odd number that drive sprocket 4 twines all flap tube sprocket wheel 5(flap tube sprocket wheels by 6 one-tenth S shapes of chain, as 3,5,7 etc.) and flap tube sprocket wheel is to be positioned on 7 in the flap tube, so motor 1 rotates, flap tube 7 will be done intermittently to rotate at a slow speed.Because sheave is four grooves, (the three-flute instability may produce and beat) each rotational angle is 90 °, when we make 4:3 to the gear ratio of drive sprocket 4 and flap

tube sprocket wheel

5,7 in flap tube can rotate 120 °, flap tube 7 when rotating 120 °, is just in time changed one side for the long tube of equilateral triangle.The advertisement plane is changed once.

The purpose that time is regulated reaches in the following manner: the pass 8, stroke sky and the time relay 9 are installed on power circuit, on the thumb wheel of Geneva mechanism, adorn a contact, load onto travel switch 8 in corresponding position, rotate 90 ° of back contacts of sheave at thumb wheel and touch travel switch 8, make it outage, motor 1 stall.And the time relay 9 can be regulated conduction time as required, and then, electric current is connected automatically, and motor rotation, flap tube rotate one side again, go round and begin again, and have become " time regulated type flap billboard ".According to the place needs, can make " suspension type time regulated type billboard " as Fig. 1 and " place formula time regulated type billboard " as Fig. 2, it is fixed that size can be come according to concrete needs, power becomes greatly thereupon and diminishes.

Claims

1, a kind of time regulated type flap billboard, comprise motor 1, worm reducer 2, Geneva mechanism 3, drive sprocket 4, flap tube sprocket wheel 5, chain 6, flap tube 7, travel switch 8, the time relay 9, shell 10 compositions, it is characterized in that: it is by motor 1 interlock worm reducer 2, drive Geneva mechanism 3 again, drive drive sprocket 4 again, drive sprocket 4 is associated in all flap tube sprocket wheel 5 usefulness chains 6, the travel switch 8 and the time relay 9 have been installed on power circuit, and the contact of travel switch is positioned on the thumb wheel of Geneva mechanism 3.
