Description

Rolling type changes wide announcement device

The utility model belongs to the advertisement display device that can move face certainly, and what be specifically related to is that a kind of rolling type changes wide announcement device.

The existing advertising device that can change picture automatically has two kinds, and a kind of is the electronic curtain formula, this advertising device complex structure, cost an arm and a leg, and picture displayed three-dimensional poor, visual effect is bad; Another kind is a turnover plate type, to be the prism that rotates with motor drives realize the conversion of advertisement drawing as the carrier of picture for it, and this device tool manufacture craft requires height, complex structure, cost height, picture to exist the shortcoming that a lot of slits make that image sharpness is not high in the junction of prism.

The purpose of this utility model is above-mentioned technology is improved, and provides a kind of rolling type slim, simple in structure, flexible and convenient to use to change wide announcement device.

The purpose of this utility model is achieved in that the utility model comprises framework, picture, rotating shaft, motor and automatic control circuit, rotating shaft comprises plurality of fixed axle and a regulating shaft, the number of stationary shaft is determined according to the width of cloth number of drawing, stationary shaft is fixed on the framework by ball bearing, regulating shaft is fixed on the regulating tank of framework by the ball bearing adjustable ground, picture is a closed, directly walk around each rotating shaft with tensioning state, when the length of picture and requirement have error, can adjust the position of regulating shaft along regulating tank, thereby make picture keep tensioning state; The line shaft of motor links to each other with a stationary shaft by gearing, this stationary shaft promptly is equivalent to main drive shaft, regulating shaft and remaining stationary shaft promptly are equivalent to driven shaft, owing to adopted ball bearing, so the transmission between each rotating shaft need not gearings such as belt or gear, when motor operation,, the rotation of main drive shaft drives the driven shaft rotation thereby will directly driving picture rolling.Control by automatic control circuit, when a complete drawing shows, motor stops operating, picture still gets off, when after a period of time of setting, motor is entry into service again, and picture scrolling motor after another complete drawing occurs again shuts down again, so circulation is gone down, realize advertisement picture move face certainly.

Advantage of the present utility model is: the utility model adopts picture directly to walk around the mode of each rotating shaft and need not other rotation vector, and adopted ball bearing, transmission between each rotating shaft need not complicated apparatus as belt grooves and belt etc. are set, so the utility model is simple in structure, cost is not high; Owing to be provided with regulating tank and regulating shaft, the utility model uses easily, and is not harsh to the length requirement of picture; Because the number of rotating shaft can determine on demand that the utility model not only can be versatile and flexible, and thinner thickness.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of the utility model embodiment 1 middle frame.

Fig. 2 is the annexation synoptic diagram of the utility model embodiment 1 shaft and picture.

Fig. 3 is the structural representation of the utility model embodiment 2 middle frames.

Fig. 4 is the annexation synoptic diagram of the utility model embodiment 2 shafts and picture.

As depicted in figs. 1 and 2, the utility model embodiment 1 is four picture types, and as shown in Figure 3 and Figure 4, embodiment 2 is the three-picture type.

As depicted in figs. 1 and 2, the framework 1 of embodiment 1 is square, six rotating shafts are installed on framework 1, rotating shaft is installed on the framework 1 by ball bearing, picture 2 is an enclosed type, the connection of sealing place of picture 2 adopts slide fastener to connect, install with convenient, dismounting or replacing inner body, picture is made by advertisement cloth or film, walk around each rotating shaft with tensioning state, rotating shaft is divided into five stationary shaft 3 and a regulating shaft 4, wherein regulating shaft 4 is fixed on the regulating tank 5 of framework 1, and the position of regulating shaft 4 can be adjusted as required, when promptly installing when the length of picture 2 when requiring some error, can move up and down regulating shaft 4 along regulating tank 5, make after picture 2 tensionings secured adjusted axle 4 again.The line shaft of motor 6 links to each other with a stationary shaft 3 of framework 1 back upper place by wheel box, this stationary shaft 3 promptly is equivalent to main drive shaft, regulating shaft 4 and remaining stationary shaft 3 promptly are equivalent to driven shaft, owing to adopted ball bearing, so the transmission between each rotating shaft need not belt or cogwheel gearing, when motor 6 runnings,, the rotation of main drive shaft drives the driven shaft rotation thereby will directly driving the scrolling of picture 2.The operation of present embodiment is controlled by automatic control circuit, the picture 2 of present embodiment is divided into four width of cloth drawings, side at each width of cloth drawing is provided with a triggering sheet metal, in framework 1 front is that the advertisement display surface position corresponding with triggering sheet metal is provided with the triggering joint, triggers joint and is connected with automatic control circuit.When connecting with the mains, motor 6 is in normally closed joint, motor 6 drives picture 2 scrollings, when a complete drawing shows, trigger sheet metal and contact with triggering joint, so timer picks up counting, relay disconnects motor 6 and power supply simultaneously, motor 6 stops operating, picture 2 is static to get off, when timer meter during to time of setting, and the circuit counter-rotating, motor 6 and power connection, picture 2 scrolling again triggers sheet metal and contacts with triggering joint after another complete drawing occurs, and causes that again timer picks up counting and motor stops operating, so circulation is gone down, and realizes the automatic conversion of drawing.

As shown in Figure 3 and Figure 4, the structure of embodiment 2 is similar to embodiment 1, and difference just is that the number of rotating shaft is different with the position of arrangement, also has the position difference of the regulating tank of establishing on the framework 15 in addition.

The above only is two embodiment of the present utility model, the utility model can also be made five picture to eight picture types, mainly realize by the number and the arrangement position that change rotating shaft, for example:, promptly become five picture types or six picture types if in embodiment 1, increase by two stationary shaft 3 that are equivalent to driven shaft at upper-lower position.

The utility model both can have been made daylight type or shot-light type, also can in the display surface of framework 1 light be set and become lamp box type.
