Description

Mechanical multi-picture automatic advertising light box

The utility model relates to advertising lamp box, the automatic advertising lamp box of the many pictures of specifically a kind of mechanical type.

Before the utility model proposes, I had once applied for the utility model patent of " the automatic billboard of the many pictures of mechanical type " to Patent Office of the People's Republic of China on September 17th, 1992, application number is 92233595.8, this patented claim is that the change in pattern that exists at conventional billboard is few, the problem that direction is single puts forward, though it is many that it has advertisement picture quantity, towards advantage such as wide, but its drive mechanism complexity, cost is too high, and with regard to its billboard itself, what it still adopted is original boarding, like this, night advertising design effect be not very desirable.

The purpose of this utility model is undesirable at the advertising design effect that exists in the above-mentioned prior art, the problem that cost is too high, picture post and gear train in " the automatic billboard of the many pictures of mechanical type " patented claim are improved, and it is bright to propose a kind of clear patterns, designs simplification the automatic advertising lamp box of the many pictures of mechanical type.

The utility model is mainly by triangular prism lamp box 1, support 2, sprocket wheel, transmission shaft 3, speed reduction unit 4, motor 5 and limit switch X form, wherein, the axle journal 15 at triangular prism lamp box 1 two is bearing on the axle 14 by bearing 13, be fixedly connected with three sprocket wheels 7 on each axle journal 15 respectively, 8,9, on the axle 14 in triangular prism lamp box 1 light source 16 is housed, light transmissive material is adopted on triangular prism lamp box 1 and surface 17, many triangular prism lamp boxes 1 on support 2, have been covered with side by side, two of each triangular prism lamp box axle 14 all connects firmly on support 2, sprocket wheel 19 is housed on transmission shaft 3, sprocket wheel 19 links by the sprocket wheel 7 on chain 12 and all triangular prism lamp box axle journals 15, chain 10,11 respectively by adjacent two triangular prism lamp box middle sprockets 9,8 all triangular prism lamp boxes 1 link up in twos, transmission shaft 3 is driven by motor 5 by speed reduction unit 4, limit switch is positioned on the bar 18, and it is by the collision block P control that is positioned on the triangular prism lamp box 1.

The aforesaid prior art of texture ratio of the present utility model is greatly simplified, and cost has reduced many.Because it is provided with light source in lamp box 1, light transmissive material is adopted on the surface of lamp box 1 again, thereby the advertising design on triangular prism lamp box 1 is clear bright, especially night result of use even more ideal.The utility model has thoroughly solved above-mentioned existing in prior technology deficiency, and it is many towards advantage such as wide also to have kept in the prior art advertisement picture quantity simultaneously.

Following reference embodiment shown in the drawings specifically describes the utility model.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the structural representation of triangular prism lamp box 1.

What the embodiment that Fig. 1 to Fig. 3 represents adopted is vertical structure.Support 2 has A, B two sides, many triangular prism lamp boxes 1 on A, B two sides, have been covered with respectively side by side, two of triangular prism lamp box axle 14 connects firmly on support 2, a transmission shaft 3 parallel with triangular prism lamp box 1 is housed in the bottom of support 2, speed reduction unit 4 and motor 5 are placed on by support 2 bottoms, be equipped with two on the top of support 2 and pass bearing up pulley 6, be used for two chains 12 of tensioning.What the outside surface 17 of triangular prism lamp box 1 adopted is transparent organic glass, and the xsect of triangular prism lamp box 1 is an equilateral triangle, and what the light source 16 on lamp box 1 inner axis of heart 14 adopted is the fluorescent tube of arranging vertically.Present embodiment has two pictures of A, B, three limit switch X1, X2, X3 are positioned on the bar 18 of A face inboard, a collision block P respectively is housed on the seamed edge of three triangular prism lamp boxes 1 on the corresponding with it A face, collision block P1, P2, P3 differ 120 ° each other, other has three time relay T1, T2, T3 to link with three limit switch X1X2, X3 respectively, and motor 5 is by these three time relay controls.

Present embodiment has two-way six picture functions, can realize functions such as the persisting of advertisement picture, renovation automatically.When system brings into operation, the rotation of driven by motor transmission shaft, make all triangular prism lamp box 1 rotations by chain 12, picture begins turning, when new picture put in place, limit switch X was started by collision block P, and motor 5 suspends, picture shows (time relay T control) behind the certain hour, and motor 5 starts again and repeats above-mentioned action.Like this, the picture of A face and B face can change three times.

The utility model can adopt horizontal type structure, and picture can have a plurality of, and its principle of work is the same.
