Description

Mechanical type walking advertisement board

The utility model relates to particularly a kind of mechanical type walking advertisement of advertising equipment board.

Movable billboard is favored by the user deeply with big, the fast changing advantage of its information capacity.They can be divided into electronic type and mechanical type two big classes by its drive principle.Electronic type walking advertisement board conversion picture is box lunch fast, but needs a large amount of electronic components, cost of manufacture height, poor reliability, maintenance difficult.General mechanical type adopts the whole space of a whole page to drag conversion, and its mechanism's heaviness, conversion is not nimble, consumed power is big, thereby the user is hung back, and especially aspect conversion synchronously, is prone to mechanical fault, and application is subjected to certain limitation.The utility model patent of application number 93200170 " three wide announcement board apparatus " is to be combined by billboard bracing frame, one group of equilateral triangle bar, one group of equilateral triangle pedestal, a motor, an opto-electronic conversion phase controller and commutating tooth wheels.Be characterized in utilizing the mode of commutating tooth wheels to rotate, drive triangular pelvis and rotate; Utilize opto-electronic conversion phase controller control motor running time and switching rate.It has overcome the defective that common used motor must not stopped transport to be changeed and can't adjust switching rate.But it is hybrid that it still belongs to a mechanical electronics.In mechanical aspects, must drive whole triangular pelvis and rotate, still heavy; And aspect electronics, having used the opto-electronic conversion phase controller, cost also can be very not low.

The purpose of this utility model is to avoid the weak point in the above-mentioned background technology and provides that the instantaneous synchronous conversion of a kind of energy, power are lower, the walking advertisement board of Purely mechanical.

The purpose of this utility model can reach by following measure:

The utility model walking advertisement board be by motor 1, reducer casing 2, a cover transmission controlling mechanism, and the walking advertisement space of a whole page is formed.Transmission controlling mechanism comprises gear, chain and time distributior, and the latter is a pair of intermeshing big or small gear set 3, two gears of so-called " engagement ", and it all is identical requiring its profile of tooth, tooth pitch, tooth depth etc.Wherein gear wheel a removes most of tooth, and the tooth top that breaks away from pinion wheel b to this part sector promptly when a rotates, makes and removes that section of tooth arc and slip on the tooth top of b, unlikelyly makes the b rotation, and b rotates in most of the time in 1 week at a be actionless; Gear wheel a remainder has the arc length of toothed portion to be equivalent to 1/3 of pinion wheel b circumference, and total number of teeth of b must be able to be divided exactly by 3.A changeed for 1 week like this, and b just changeed for 1/3 week, and promptly when the engagement of a/b group, b is rotated 120 ° of central angles, and like this, a/b gear set 3 just becomes a time distributior.Set the gear a radius different, just can design different moving/quiet time ratios with b.Gear b has that section arc of that part of segmental arc correspondence of tooth with a, and its central angle is 120 °.This pinion wheel b draws its torque by synchromesh gear b ', drives several identical with it gear B by chain 4 again and links with b, and they also are under time distributior control, when a changeed for 1 week, and b, b ' and B etc. changeed for 1/3 week.Again by these transmission gears B drive activity space of a whole page.

The movable space of a whole page is to be put together by the logical heart straight tube 6 (to call " triangle is straight-through " in the following text) that some sliver transvers sections are equilateral triangle, and the bar number depends on the height or the width of billboard.Each root " leads directly to " three identical outside surface, allows one of them surface arrangement at grade to form the space of a whole page, can arrange by vertical or horizontal mode.Be supported on the bearing seat then.Every " leading directly to " of the space of a whole page serves as that axle rotates synchronously with its center line under gear B driving separately, changes hexagonal angle at every turn, and a rotation period changes 3 times, reveals three surfaces, becomes the walking advertisement board of one three turnover panel.

The mode that drives " triangle is straight-through " can adopt the direct transmission of two supports.Every " triangle is straight-through " is by two minor axises 8,8 ' respectively is vertical and be fixed to the center of both ends of the surface, support to bearing pack 7,7 ' on, the other end of minor axis 8 is vertical and be fixed on the axle center of gear B and become rotation axis, under the driving of B, each bar of making central shaft with minor axis " leads directly to " and the rotation synchronously of B do, thereby three outside surfaces of " leading directly to " are successively forwarded on the plane of forming the space of a whole page.Like this, constituted the big system of a whole set of transmission from gear a-b-b '-B-minor axis to " triangle straight-through ".

" triangle is straight-through " can be made through extrusion process by aluminium alloy, becomes " triangle aluminium is logical " of aluminium matter.This " triangle aluminium is logical " can carry out the heat-tinting processing, with means such as japanning, stickups, by literal, pattern, color, behind the making space of a whole page, again through the heat-tinting second time of different colours.

Also can be placed within the space of a whole page framework 5 by " triangle is straight-through " 6 assembled whole spaces of a whole page.The running of motor 1 can be sent electric signal by a long-range controller and be controlled.

The utility model walking advertisement board has following advantage:

1, mechanism is light, rotative power is low.Because with the whole space of a whole page " change face is a line ", do not need the whole space of a whole page dragged and change picture, the wall scroll that is resolved into by face " need only lead directly to " 120 ° of rotations, can realize the significantly conversion of the space of a whole page.In addition, use lightweight and " aluminium is logical " of hollow, only need at the both ends of the surface peripheral hardware one minor axis axle that rotates, save one long and run through the rotating shaft at " triangle aluminium is logical " center, greatly alleviate deadweight (and reduce cost, the precision of the space of a whole page is greatly improve also).All these make the mechanism of whole billboard light, have reduced the required rotative power of the conversion space of a whole page.

2, conversion is rapid, and synchronism is good.The mode of this conversion space of a whole page concerning each bar " triangle is straight-through ", because its circumcircle radius is little, only needs to rotate very short one section camber line, almost can accomplish instantaneous conversion.And because the synchronism of gear one chain transmission system is good, the rotation of each gear B is synchronous, and every " leading directly to " also can rotate identical angle, overall fitting harmony, nature synchronously.Also be convenient to handle its operation by the electric signal that remote-operated controller sends.

3, Purely mechanical does not need to control with photoelectric tube.All parts adopt assembling mode, are convenient to transportation and maintaining.

4, it is painted that the space of a whole page adopts secondary oxidation, clear patterns, attractive in appearance; The look film is firm, not fugitive color.
