Description

Gear multi-picture sequence changing advertisement unit

The utility model belongs to the technological improvement of advertisement board structure.

Should not very fast change behind the regular price-line advertising board Patten drawing, the time is difficult for having caused people's interest once long advertising design.In order often to change advertising design, microcomputer-controlled electronic bill-board has appearred, and it is change pattern arbitrarily, and it is various to be lively in form, very noticeable.The display screen of this electronic bill-board generally will be made up of thousands of light emitting diodes, and the high impact endurance test shock that is unable to undergo again of cost very easily damages, thereby limited its use.

Adopted the mechanical type advertisement device that can change picture in proper order in order to overcome above-mentioned shortcoming the utility model, adopt the structure of the moving equilateral triangle roller rotation of incomplete cross helical gear subband, realize picture descend from last (descend) (on) or from a left side (right side) and the order variation on the right side (left side).This gear type order conversion multi-picture advertisement utensil has the electronic bill-board pattern to change, noticeable advantage, do not have electronic bill-board not shock-resistant again, the shortcoming that cost is high can reach the purpose that can attract people's interest can reduce advertising expenditure again.

To the effect that of the present utility model: the corresponding plane that picture is arranged with several equilateral triangle roller sequential parallel combines.Adopt the moving equilateral triangle roller rotating shaft of the three-dimensional crossing rectangular incomplete cross helical gear subband of axis of rotation to rotate the drive mechanism that changes picture.The incomplete cross helical gear of flanged pin dish circles, and makes 120 ° of the cross helical gear revolutions and the triangle roller that have three straight troughs that are spaced from each other into hexagonal angle rotate 120 °, conversion one subframe.The equilateral triangle roller rotates a circle, three kinds of change in pattern.For picture smooth, after 120 ° of the every rotations of equilateral triangle roller wherein each equilateral triangle roller constitute a plane of picture all should be at grade, it is minimum that the gap between its per two adjacent equilateral triangle roller pictures plane should be.Not exclusively helical tooth wheel set and flange adopt metal or plastics to make, and the equilateral triangle roller adopts wood, fiberglass, plastics or metal material to make, and rotating shaft of equilateral triangle roller and incomplete cross helical gear rotating shaft are made with metal material.

The utility model has the advantages that: 1. existing e-advertising pattern can change, fresh attracting advantage, and firm shock-resistant, non-damageable advantage is arranged again.2. not exclusively helical tooth wheel set positive drive, the functional reliability height.3. mechanism is simple, easily manufactured.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the utility model advertisement device picture structure synoptic diagram.Fig. 2 is an A-A diagrammatic cross-section among Fig. 1.3 figure, Fig. 4 are that incomplete helical tooth wheel set drives equilateral triangle roller synoptic diagram.Fig. 5, Fig. 6, Fig. 7, Fig. 8 are respectively B-B among Fig. 4, C-C, D-D, E-E diagrammatic cross-section, among the figure: 1 framework, 2 rotating shafts, 3 rolling bearings, 4 sliding bearings, 5 equilateral triangle rollers, 6 spiral garden stud wheels, 7 incomplete spiral garden stud wheels, 8 rotating shafts, 9 incomplete flanges.The C framework left side, D framework the right.A straight trough width, b chimb width, m two adjacent equilateral triangle rollers corresponding two interplanar gaps, α is an angle.

The board face of the utility model advertisement device is formed above being contained in framework 1 by several equilateral triangle rollers 5 in Fig. 1, Fig. 2, Fig. 3.Several equilateral triangle rollers 5 respectively are contained in the rotating shaft 2 of sequential parallel arrangement.The rotation of equilateral triangle roller 5 is formed by the line of centres of equilateral triangle, and coincides with rotating shaft 2 rotations.2 of rotating shafts on each equilateral triangle roller 5 are on framework 1 left side C rolling bearing 3 and on the right D sliding bearing 4.Equilateral triangle roller 5 descend from last (descending) (on) back is from a left side (right side) and right (left side) every order is rotated and once is 120 °, turns over a plane of equilateral triangle roller 5, pattern promptly changes once, rotates a circle, pattern can change three kinds.

In Fig. 3,4,5,6,7,8, the same distance place, end of every rotating shaft 2 close rolling bearings 3 all is fixed with an identical spiral garden stud wheel 6.7 engagements of corresponding with each the respectively incomplete spiral of each spiral garden stud wheel 6 garden stud wheel.Each 7 is fixed on the common shaft 8, and 8 axis of rotation and each axis of rotation solid of 2 meet at right angle.It is the garden cylinder that 7 garden Zhou Fangxiang goes up major part, have only definite part garden cylinder above done helical tooth, the ratio Z7:Z6=1:3 of its tooth number Z 7 and 6 tooth number Z 6.Be shaped on diameter on one side end face of 7 garden cylinder partial greater than spiral tooth top garden on 7 and the incomplete flange 9 of chimb of certain width b is arranged.6 end face upper edge gear Width is opened and is spaced from each other into three identical straight troughs of 120 °, and its width a is slightly larger than 9 width b.The structure of directly making chimb on the position on 6 end faces and 9 should meet following condition: when 8 drives, 7 revolutions, helical tooth on 7 drives 6 revolutions, after helical tooth on 7 all turns over, 6 when no longer rotating, chimb on the flange 9 should be able to enter in the corresponding straight trough on 6 this moment smoothly, after the flange chimb has all changeed, can withdraw from straight trough smoothly, and make 6 once more with 7 on helical tooth mesh smoothly.Because of 7 helical tooth tooth number Z 7 and 6 helical tooth tooth number Z 6 ratio 1:3, therefore 7 turn over whole teeth after, even 6 turn over 120 ° of whole gear also 2 or triangle roller 5 turn over 120 °, also promptly turn over a plane of 5 of equilateral triangle roller, finish the conversion of a picture pattern.Continue revolution this moment as 8, therefore 7 anodontia and 6 engagements the time, 6 can not rotate and 9 chimb begins to enter on 6 in the corresponding straight trough again, and one has rotated until chimb, helical tooth on 7 once more with 6 on tooth when engagement till, this equilateral triangle roller just is in self-locking and turn state not always.Having turned over three to 8 or 7 changes promptly 6 and turns over the conversion that a roller of equilateral triangle when changeing 5 has just been finished three pictures, three kinds of change in pattern.If descend from last (descend) (on) or from a left side (right side) and the equilateral triangle roller 5 on right (left side) to have n individual, when turning over a week (also be equivalent to 6 and turn over 120 °) for hope 8 or 7, the replacing that a certain picture of n root equilateral triangle roller 5 or respective planes can both be carried out picture or respective planes continuously successively once, it is just necessary: when the helical tooth on the helical tooth on first triangle roller 5 pairing 7 forwards to just with corresponding 6 is meshed, helical tooth reference position on the 2nd triangle roller 5 pairing 7 is with respect to a α=(300 °)/(n) angle that should lag behind of the helical tooth reference position on the 1st the triangle roller 5 pairing 7, helical tooth reference position on the 3rd triangle roller 5 pairing 7 should lag behind one 2 jiaos with respect to the helical tooth reference position on the 1st the triangle roller 5 pairing 7, and the like.N equilateral triangle roller be at revolution 300 ° less than a week in other words, descend from last (descend) therebetween (on) or from left (right side) and the right side (left side), every just there being a corresponding plane to change picture successively.
