Description

The automatic conversion display device of many pictures

The utility model relates to the display device of a kind of billboard and advertisement, belongs to controllable type mechanical driving device technical field.

The display device of existing billboard and advertisement, Billboard is single advertisement picture mostly, its structure of electronic display unit is quite complicated again, the cost height, and the advertisement form of single board one picture has not caught up with situation, and because picture still, pattern is outmoded, quantity of information is few, all inapplicable, in order to replenish above deficiency, recently the display device that some two pictures and many pictures have occurred, various informative, reasonable idea, solve some and had not enough problem, but be still waiting to improve, Chinese patent CN2057017Y discloses the automatic conversion display device of a kind of many pictures, CN2076260Y discloses three billboards of a kind of combined rotary, its structure is by support, motor, be fixed on that finger on the output shaft of motor and controller are formed and with main frame, display device that motor speed-changing device and power transfer combine and billboard, owing to be subjected to the restriction of plate face, the picture amount of increase is many not enough, the picture displayed number generally all is difficult to surpass ten width of cloth, on the size design of billboard breadth, also be restricted, thereby the user selects the degree of freedom of billboard breadth lower, not very good.

The purpose of this utility model is in order to solve the deficiency that above-mentioned prior art exists, a kind of automatic conversion display device that can show that the above picture information amount of 12 width of cloth pictures is big is provided, and can be with a width of cloth picture two or four display surface cocycles demonstrations in display device, increase user's choice, thereby it is noticeable with different transform, strengthen advertising effect, substituted large-scale electronic display unit.

The purpose of this utility model realizes with following scheme: by framework, motor, power axle, toggle, smooth detent mechanism of picture page group and picture page and control circuit are formed, framework is a rectangle frame, size is suitable with a width of cloth picture, frame thickness is the thickness of display device, it is a plurality of at the upper and lower surface of framework power axle to be housed, per two pairs is one group, between power axle, be provided with picture page, be fixedly equipped with shift fork on the power axle, the group number of power axle is determined jointly by the width of a width of cloth picture and the width of picture page, the picture page group is to be fixed on the flexible transmission chain by picture page, be provided with detent, travel switch and control circuit, motor drags toggle, toggle drives all power axles and rotates synchronously, and the picture page on two sides overturns simultaneously before and after the display device under the stirring of shift fork, finishes the conversion simultaneously of display device front and back two pictures.

For realizing that such scheme is provided with smooth detent mechanism on display device, be fixed on the framework by the right-angled intersection connecting rod, two ends at the right-angled intersection connecting rod are fixed with clamping plate respectively, two sides clamping plate before and after the spring tension, two adjacent hinge pivot pins of pivot pin are equipped with pulley up and down in the middle of the right-angled intersection connecting rod has gathering sill and right-angled intersection connecting rod, following small sheave can slide in gathering sill, above be provided with the bar shaped link stopper between two small sheaves, bar shaped link stopper promotion small sheave outwards slides along gathering sill when the picture page or leaf overturns like this, the right-angled intersection connecting rod then stretches out to both sides, promote clamping plate and allowed the upset of picture page, after the picture page upset, clamping plate compress the edge on two sides, display device front and back under the spring tension effect, make the smooth location of two pictures.

In order to realize that the such scheme power axle drives the minor axis that rotates synchronously by the crank connecting link machine respectively at the framework upper and lower surface, power wheel on the power axle can be circular or oval, which is provided with double wedge or recessed tooth, it and flexible transmission chain fovea superior tooth or double wedge engaged transmission.

In order to realize that such scheme is provided with orienting lug or angle sheave on picture page two ends or flexible transmission chain, on framework, slide in the gathering sill, on the face between two picture pages, be provided with thin flexible material overlayer, when being opened, two picture pages become a positive picture, and between picture page, be provided with resilient material, make picture page under the drive of flexible transmission chain, do not swing, also play power transmission simultaneously.

Also can be designed to water chestnut cylindricality framework according to this display device of such scheme, the triangular prism of power wheel and composition picture is housed on framework, the quantity of triangular prism is determined jointly by the width and the triangular prism width on one side of picture, the axle sleeve at the two ends of triangular prism is contained in the axle sleeve that is fixed on the flexible transmission chain, guide runner is arranged on the axle sleeve, slide in the gathering sill of guide runner in framework, flexible transmission chain drives triangular prism and moves in framework under the transmission that power wheel is established, power wheel is provided with the tooth engaged transmission on tooth and the driving-chain, be provided with switching mechanism in the framework, by turning wheel, slide block and pivot pin and gathering sill composition fix on the support, support is fixed on the framework, power wheel rotates under driven by motor, and the picture that drives triangular cylinder composition moves in four display surface cocycles of framework.

For triangular prism can be overturn simultaneously in moving automatically, the place, two obtuse angles in water chestnut cylindricality framework respectively is provided with a switching mechanism, and switching mechanism is by turning wheel.Pivot pin and support are formed, turning wheel is fixed on the support and can freely rotates with pivot pin, support is fixed on the framework, form angle sheave, the distance that takes turns to the gathering sill center line that guarantees to overturn equals the distance of the limit of triangular prism to the axle center, when triangular prism moves through place, framework obtuse angle under the effect at turning wheel, triangular prism is upset one side automatically successively like this, finishes the automatic conversion of four display frames in circulation is moved.

Flexible transmission chain can be bush roller chain or cog belt or finer wire or nylon rope formation, and this slide block can be a small sheave, and simultaneously, water chestnut cylindricality framework can be a rectangular frame.Can show 12 width of cloth pictures, be a kind of single face display device, and triangular prism is finished the conversion of picture successively by switching mechanism.

The utility model has following advantage compared with the prior art: the picture that the technical program demonstration 12 width of cloth capable of circulation are above, having solved picture can not several pattern, can transmit a large amount of picture information, and have the advantages that two-sided circulation shows or the four sides circulation shows, increase picture information and transmitted the space, noticeable with different transform, strengthened the effect of advertising.
