Description

A kind of advertising lamp box that can two-sided roll display

The utility model relates to a kind of advertising carrier.What be particularly related to is a kind of advertising lamp box.

Chinese patent 94230273.7 discloses a kind of " the wide announcement lamp box of computer multipage ", and its formation comprises casing, be located at light source in the casing, reflector, winding up roller, guide roller and be made of the motor and the speed reduction unit of computer control.Its less than one is can only single face to show, fails fully effectively to utilize the ability of light source and transmission facility; The 2nd, by the kinematic train more complicated of computer control, and the cost height.

The purpose of this utility model is the above-mentioned shortcoming that overcomes existing advertising lamp box, provides a kind of drive mechanism simple, advertising lamp box that can two-sided roll display.

The advertising lamp box of realizing the purpose of this utility model comprises casing, light source, winding up roller, guide roller and winding up roller drive unit, described casing has two display windows relatively, light source is located in the middle of two display windows, guide roller is arranged symmetrically in display window inner side edge place, described drive unit is by motor, be connected in the reverse mechanism on the motor shaft, the driving chain that is arranged on the sprocket wheel on the winding up roller axle and is connected between winding up roller sprocket wheel and the reverse mechanism constitutes, and described reverse mechanism is by a pinion wheel that joins with motor shaft, and the wobble wheel of pinion and be connected in pinion wheel and wobble wheel between swing arm, be located at the transmission gear on wobble wheel both sides respectively and constitute with the sprocket wheel of the coaxial setting of transmission gear.

Principle of work of the present utility model is as follows:

Two isometric cords that are painted with the advertisement picture content are twisted on the winding up roller with back-to-back reduplicative forms, article two, the other end of cord then draws two cords toward two display windows respectively through guide roller respectively, and leading in an overlapping through another guide roller again, shape twists on another winding up roller.The rolling of cord then drives wobble wheel in the commutator by motor shaft, is driven at it certain on one side transmission gear and sprocket rotation again, is driven the rotation that sprocket rotation on the winding up roller drives winding up roller by chain again and realize by wobble wheel.After cord is rolled onto head, the motor counter-rotating, driving swing arm makes wobble wheel swing to the transmission gear of another side and be engaged with, thereby driving the chain commentaries on classics/chain that links to each other with another winding up roller rotates, promptly serve as initiatively winding up roller rolling cord, the winding up roller of before having served as the rolling cord then serves as driven winding up roller and emits volume cord thereon under the dragging of cord.

An elastic damping mechanism is set on the drive sprocket end face of commutator, can makes it when serving as engaged wheel, keep synchronous, thereby make cord keep certain rate of tension with driving wheel.

On the end face of the transmission gear of commutator, an elastic damping mechanism is set, equally also can plays the effect that is synchronized with the movement, keeps the cord tensioning.

Still can dispose a specified time apart from transmission control device to motor, motor be dragged in the moment of setting stop after cord reaches certain-length, stop dragging cord once more after a period of time and reach certain-length.Can make single width advertisement picture page on the cord be clearance-type like this rolls and manifests.This specified time can be used existing electronic-controlled installation apart from transmission control device, one of scheme is to join a timing starter and establish a sensor in casing to motor preferably, when the rotation of the cord length of finishing a single width advertisement picture, by the sensor sense and signal passed to motor, make the motor stall, when stall behind certain hour, regularly starter makes electric motor starting drag cord, by sensor motor is stopped again.

The utility model has the advantages that two-sided reciprocal roll display simultaneously, made full use of the ability of light source and running part, enlarged the advertisement length and shown scene, and transmission structures simple, easy to manufacture, be applicable to various advertisement occasions.

Provide embodiment below in conjunction with accompanying drawing.

Shown in Fig. 1～4, formation of the present utility model comprises and has two display windows 1 relatively, 2 casing 3, be located at the light source 4 between two display windows, on symmetry is located in the casing, the last winding up roller 6 at upper/lower positions place, following winding up roller 7, be arranged symmetrically in the guide roller 8 at display window inner side edge place, 9,10,11 and by motor 12, be connected in the pinion wheel 13 on 12 in the motor, wobble wheel 14 with pinion wheel 13 engagements, be connected the swing arm 15 between pinion wheel 13 and the wobble wheel 14, be located at the transmission gear 16 on wobble wheel both sides respectively, 17 and with the sprocket wheel 18 of transmission gear 16 coaxial settings, the reverse mechanism 5 that is constituted with the sprocket wheel 19 of transmission gear 17 coaxial settings and be arranged on that 6 of windings up roller are gone up and sprocket wheel 18 corresponding sprocket wheels 20 and be connected in driving chain 21 between sprocket wheel 18 and 20, be arranged on down on 7 of the windings up roller and sprocket wheel 19 corresponding sprocket wheels 22 and be connected in driving chain 23 between sprocket wheel 19 and 22.One end of described swing arm 15 is connected on the axle 24 of wobble wheel, the other end then joins with pinion wheel 13 by an axle sleeve 25 and a spring 26, wherein, axle sleeve 25 and motor shaft are movingly, with swing arm 14 stationary fits, one end of axle sleeve touches mutually with the end face of pinion wheel 13, and 26 apical graftings of spring are between the other end and commutator end bearing bracket 27 of axle sleeve.The friction force of utilizing spring 26 to impose between axle sleeve and pinion wheel end face can realize driving swing arm when motor reverses and wobble wheel is dialled to the another side joggleword.Light source 4 is served as by some uniform daylight lamps in the present embodiment.Double dot dash line is the outline line of cord 35 among the figure.

For guaranteeing the rate of tension of cord 35, be located on the end face of drive sprocket 19 elastic damping mechanism as shown in the figure, be fixed on the nut 28 on the commutator housing and be socketed in the screw rod 29 in the nut and the damping block 31 that is located at the spring 30 of screw front end and is located at the spring front end is constituted by one, utilize the screw rod regulating spring to put on pressure on drive sprocket 19 end faces, can make the rotating speed of drive sprocket 19 and corresponding drive sprocket 21 make cord 35 keep tensioning synchronously by damping block.

As a same reason, this damping mechanism also can be arranged on the end face of transmission gear.Fig. 5 has provided the structural representation that is located on transmission gear 16 end faces.

Set up a specified time that constitutes by sensor 32 and timing starter apart from the transmission control device (not shown) for motor 12, still can make this advertising lamp box possess interval certain hour scrolling cord changes displaying contents to certain-length, a timing automatic function.
