Abstract
The utility model relates to a new electric turn-up billboard which adopts the structure that a heteromorphic cam fits with an oriented shifting block, which replaces common chains and chain wheels, worm wheel and worm gear transmission devices, electronic control units, or relay control circuits. The utility model has the advantages of high reliability, strong applicability, convenient assembly and disassembly, accuracy position when the picture turns-up.
Description
The utility model belongs to billboard display technique scope.
The pivoted billboard of multiaspect circulation electric is a kind of novel advertisement apparatus of releasing in recent years, generally adopt the electronic circuit or the time relay to control the commentaries on classics of motor, stop, by mechanical drive (chain and sprocket wheel or worm gear, worm screw etc.), realize control to billboard.The Fraquent start of motor influences its serviceable life, and existing this mechanical driving device is heavy, is not easy to convey in sections.
The purpose of this utility model be to provide a kind of mechanical driving device easy reliable, be convenient to dismounting, can be at the motor billboard of timing automatic page turning under the situation of running continuously.
Basic design of the present utility model is: adopt special-shaped cam and directed shifting block fit structure, replace existing mechanical gearing and electronics or control relay circuit, realize the real-time control to billboard.
Below in conjunction with embodiment (the upset cylinder is a triangle) its principle of work is done and to be specified.Fig. 1 is its structure principle chart, and Fig. 2 is its assembly structure figure.
In Fig. 1, special-shaped cam 3 is fixed on the final drive shaft 1, and its operative end surface A is vertical mutually with the axes O O ' of final drive shaft 1, and has annular groove 12, one ends to seal with cam shifting block 2, and the other end communicates with the breach 11 of special-shaped cam 3.Directed shifting block 4 is the regular polygon cylinder, each side B is a workplace, is fixing startup post 5 respectively symmetrically, and an one end face is being fixed transmission shaft 6, fixedly connected (transmission shaft 6 also can be made of one with rotation axis 13, without adapter sleeve 8) with the rotation axis 13 that stirs cylinder 7 through adapter sleeve 8.Electric motor starting is after variator drives final drive shaft 1 and cam 3 presses direction shown in Fig. 1 and rotate around OO ' axle, groove 12 and the startup post 5 relative slips that fall in it, contact with starting post 5 until shifting block 2, stir startup post 5 and drive shifting blocks 4, thereby drive cylinder 7 around axis SS ' rotation.After breach 11 arrives the relative position of shifting block 4, the startup post 5 of another workplace B of shifting block 4 will enter groove 12 and slide relatively along groove along the breach of groove 12, this will make this workplace B and end face A keeping parallelism, thereby make the next face of cylinder 7 be parked in display position, finish the once inside out of cylinder 7.When motor kept constant speed, the upset of cylinder 7 and demonstration time were all determined.
In Fig. 2, bearing support 10 is connected with the billboard frame fixation, supporting drive shaft 6(or supporting rotation axis 13), every group of shifting block 4 is flexibly with the relative position of cam 3, side thereon also can be at its downside, but will keep end face A near shifting block 4, many series cylinders 7 are arranged in parallel and constitute a complete billboard drawing, and structure such as every series cylinder, cam, shifting block is identical.After breach 11 alignment of each group cam 3 is fixing, can guarantee that each series cylinder overturns simultaneously, fix when breach 11 certain angle that staggers mutually, can realize that then cylinder overturns successively.
Unscrew screw 9, axle 13 can be extracted out convenient disassembly from adapter sleeve 8.
Special-shaped cam 3 and directed shifting block 4 preferably adopt nylon, engineering plastics to make, and can not get rusty in the open or in the wet environment, and greasy property is good.
Upset cylinder 7 preferably adopts aluminium alloy extrusions to make, and is in light weight, corrosion-resistant, attractive in appearance.
The electric turn-up billboard that the utility model provides has the following advantages:
1. strong to environmental suitability, can in-40～+ 80 ℃ of environment, work the reliability height.
2. advertisement drawing upset accurate positioning, picture is neat.
3. can realize that drawing overturns simultaneously or upset successively.
4. in light weight, easy accessibility, be convenient to carrying, safeguard.
Claims (6)
1, a kind of electronic pivoted billboard.Form by motor, variator, transmission shaft, cam, upset cylinder, scaffold, it is characterized in that: the special-shaped cam 3 that is fixed on the final drive shaft 1 has a breach 11, have annular groove 12, one ends to seal with cam shifting block 2 on its operative end surface A, the other end communicates with breach 11; Fixing 5, one end faces of a startup post on each side B of the directed shifting block 4 of regular polygon cylinder respectively fixedlys connected with the rotation axis 13 of upset cylinder 7.
2, billboard as claimed in claim 1 is characterized in that: an end face of directed shifting block 4 has transmission shaft 6, fixedlys connected with the rotation axis 13 of upset cylinder 7 through adapter sleeve 8.
3, billboard as claimed in claim 1 is characterized in that: the rotation axis 13 of upset cylinder 7 is by bearing support 10 supportings.
4, billboard as claimed in claim 1 or 2 is characterized in that: the transmission shaft 6 of directed shifting block 4 is by bearing support 10 supportings.
5, billboard as claimed in claim 1 is characterized in that: special-shaped cam 3 and directed shifting block 4 adopt nylon, engineering plastics to make.
6, billboard as claimed in claim 1 is characterized in that: upset cylinder 7 adopts aluminium alloy extrusions to make.
