Description

Photoelectric controlled turnover billboard

The utility model relates to the photoelectric control reversing advertisement board, is the product that a kind of machinery and electronic technology combine, and is applicable to that shop, street, buildings, stadium etc. are fit to be provided with the place of billboard.

In recent decades, in the advertising field, people combine many triangular prisms with various mechanical transmission mechanisms, have designed multiple convertible exploitation board.So just can on a billboard, show the picture that three width of cloth are different or represent multiple information.This billboard-like often can be seen from external magazine, picture, film and TV programme.Domestic this billboard-like that also occurred has successively in recent years all proposed the implementation method of this billboard: 88203048U, 88219362.7,89205789.0,88208594.8,89214455.6 as following number of patent application.The gear train of existing reversing advertisement board has adopted sheave transmission, worm-drive, conical gear transmission, dial transmission respectively.The shortcoming that these gear trains exist is the gear train more complicated, and transmission efficiency is lower, installs and adjusts relatively difficulty.In addition, lack electric control system in the existing reversing advertisement board, motor is in continuous duty, and consequently mechanical wear and power consumption are all bigger, and the demonstration time of each display surface is difficult for regulating the difficult realization of other subsidiary functions.For solving these weak points on the prior art, we propose the photoelectric control reversing advertisement board.

The purpose of this utility model provides a kind of gear drive reversing advertisement board with photoelectric control, safeguard protection, sound picture synchronizing function, the visible accompanying drawing of its primary structure.

Below with reference to accompanying drawing the utility model is described.

The two ends of triangular prism (2) are fixed with triangular prism major axis (20) and triangular prism minor axis (14) respectively.Rolling bearing (13), dustproof and waterproof circle (17), bearing shell (12) respectively are housed on major axis (20) and the minor axis (14), and bearing shell (12) is fixed on the framework (1) with screw (18).Triangular prism gear (4), trisection positioning cam (8), nut (21), packing ring (22) also are housed on the triangular prism major axis (20).After nut (21) was also tight, triangular prism gear (4), trisection positioning cam (8) and triangular prism major axis (20) rotated with triangular prism (2) synchronously by the combination of planar friction power.Shaft block ring (15) also is housed on the triangular prism minor axis (14) and adjusts pad (16), their effect is restriction and the axial float of adjusting triangular prism (2).Low speed synchromotor (6) is contained on the framework (1).Motor output shaft gear (5) is housed, triangular prism gear (4) engagement on motor output shaft gear (5) and first triangular prism on the output shaft of motor (6).On the framework between two triangular prism major axis bridge gear shaft (23) is housed, carrier gear (3) can be gone up flexibly at bridge gear shaft (23) and rotate.The axial float of carrier gear (3) is still by adjusting the restriction of packing ring and shaft block ring.Carrier gear (3) respectively with two triangular prism major axis on triangular prism gear (4) engagement, the power exported of motor is just by motor output shaft gear (5) → triangular prism gear (4) → carrier gear (3) → triangular prism gear (4) → carrier gear (3) like this ... hand on always.The effect of carrier gear (3) is to guarantee that every triangular prism can both equidirectionally rotate.Framework (1) adopts Seal Design at the part-structure at triangular prism two ends, can prevent that like this dust and rainwater from entering, and guarantees the operate as normal of bearing and transmission gear.Correct location in the triangular prism course of work is to realize by the steady arm of being made up of trisection positioning cam (8), roller backstay (24) and retainer spring (25).Adopt the kind of drive of the present utility model to make the processing of billboard and Installation and Debugging very convenient, only need the same display surface of triangular prism is set level, transmission gear is all meshed, put steady arm well on back and the tight triangular prism major axis nut (21) by position shown in the figure (3), promptly finished the adjustment work of display surface.On framework (1), be equipped with back-up block (11) is installed, only need just billboard to be installed on ground, wall or the buildings in that the in addition suitable support fixation thing in back-up block (11) back is installed.

The electric control system principle of work is as follows: be fixed with trisection gear piece (9) on a triangular prism major axis therein.Be fixed with Hall element (10) on framework (1), behind the power connection, the single stabilization delay circuit output low level makes thyristor gating circuit (33) work, the controllable silicon conducting, and motor (6) drives triangular prism and rotates synchronously.When the some teeth on the trisection gear piece (9) pass through Hall element (10), pulse signal of Hall element output, deliver to time sequential pulse distributor circuit (28) and single stabilization delay circuit through shaping amplification circuit (27), make single stabilization delay circuit output high level, thyristor gating circuit (33) ends, motor (6) stall until the single stabilization delay circuit output low level, repeats the above-mentioned course of work again.Because the quantity of information of three width of cloth advertisements is different on the billboard, designed time sequential pulse distributor circuit (28) and three road single stabilization delay circuits (29,30,35) in the utility model control circuit, so just can regulate three width of cloth advertisements demonstration time separately and demonstration number of times.Switch (K) couples together billboard light-operated circuit (37) and main circuit, because the light activated element resistance changes with ambient brightness, when K connects, quits work after the billboard darkness, resumes work after daybreak.Billboard work double tides when K disconnects.Switch (K) and switch (K) interlock, K disconnects when K connects, and K connects when K disconnects.K connects back lighting light-operated circuit (31) work, The night screen has hung down back lighting light-operated circuit can be glittering (be triangular prism when rotating lamp go out, lamp is bright during stall).Also can grow bright mode and make illuminating lamp (32) work, which kind of mode is by the determining positions of K switch.Light extinguishes after daybreak.Hand touches holding circuit (36) and for safety is provided with, and billboard stall immediately when the people touches billboard automatically recovers operate as normal after hand leaves, and can avoid the outdoor large reversing advertisement board accident that meets accident when the curious plate of pedestrian is done like this.Sound picture synchronizing circuit (26) is connected with main circuit by K switch, its working method is that music or the commentary that will match with ad content deposit EPROM in by computer sampling, whenever billboard upset one side, associated sound equipment is taken out to come out by loudspeaker plays from EPROM, to strengthen the effect of publicity.In the control circuit also design overload protecting circuit (34) is arranged, prevent that motor (6) from overloading and burn out under unexpected situation.

The utility model compared with prior art has the following advantages:

1, simple in structure, be easy to make and Installation and Debugging.

2, transmission efficiency height reduces mechanical wear, conservation of power.

3, can control the demonstration time and the demonstration number of times of three width of cloth advertisements respectively.

4, has the dustproof and rainproof design.

5, have the photoelectric control function, billboard can be used round the clock.

6, has safety and Protection.

7, have the sound picture synchronous device, advertising effect is strengthened.
