The utility model has the advantages of simple structure and easy realization, and the utility model can be used as a light box or an inscribed tablet.

Description

The convertible lamp box of storage type picture

The utility model relates to technical field of advertisement, and exactly it is the convertible lamp box of a kind of storage type picture.

Advertising lamp box is a kind of common advertising media, existing advertising lamp box picture is changeless mostly, a kind of electronic display advertising lamp box is arranged, and it can the more picture of conversion, but cost is very high, maintenance cost is also expensive, also have a kind of convertible billboard, relatively simple for structure, general maximum can only three kinds of pictures of conversion, and outward appearance is beautiful inadequately, and also be difficult for noticeable night.The variable lamp box of a kind of picture is also arranged, and it twists in picture to move back and forth on two axles realizes the conversion picture, uses not for a long time, and picture is sideslip just easily, thereby has limited its application.

The purpose of this utility model provides the convertible lamp box of a kind of storage type picture, and it not only can the more picture of conversion, and cost is lower, and night is also especially noticeable, and demonstration effect is good, and the scope of application is wider.

The purpose of this utility model is achieved by the following scheme: it is by casing, motor, speed reduction unit, picture, fluorescent tube and gear train are formed, it is characterized in that: unexpanded picture is box stacked the depositing of accordion behind fluorescent tube (7), be carved with protruding thorn point (12) on the main drive shaft (1), on main drive shaft (1) and the driven shaft (10) pressure roller that is close to them (2) is arranged all, the spring (3) that pressure roller (2) is mounted on the lamp box compresses, picture is contained in main drive shaft (1) and driven shaft (10) is upward compressed by pressure roller (2), and main drive shaft (1) couples together by gear train and motor (18).Gear train is that motor (18) drives big belt pulley (16) and speed reduction unit (15) by small belt pulley (19) and belt (17), drives the hinge wheel (11) that is fixed on the main drive shaft (1) by minor sprocket (14) and driving-chain (13) again and rotates.

The utility model has the advantages that convertible a plurality of pictures make an advertising media can show multinomial content; Also can make commercial board, introduce more service content; Also can store a plurality of backgrounds, and changing background is easy to as the background curtain wall in the photographer's, simple and easy to use.The long-term use of picture is difficult for sideslip, and the utility model structure is also fairly simple in addition, and cost is lower, and is easy to maintenance, realizes easily.

Below in conjunction with drawings and Examples the utility model is done further detailed description.

Fig. 1 is the utility model working state structure synoptic diagram.

Fig. 2 is the utility model mechanical driving part structural representation.

1 is that main drive shaft, 2 is that pressure roller, 3 is that spring, 4 is that lamp box, 5 is that lamp box picture hiding-place, 6 is that picture, 7 is that fluorescent tube, 8 is that tube stand, 9 is that pillar, 10 is that driven shaft, 11 is that hinge wheel, 12 is that protruding thorn point, 13 is that driving-chain, 14 is that minor sprocket, 15 is that speed reduction unit, 16 is that big belt pulley, 17 is that belt, 18 is that motor, 19 is that small belt pulley, 20 is a fixed head among the figure.

The utility model and existing lamp box are manufactured basic identical, but it has solved the problem of a masty picture sideslip, it is that lamp box is widened, with picture not exposition temporarily after being placed on lamp box, and deposit in the box stacked mode of accordion, reduced the suffered tension force of transmission shaft, increased the stored number of picture, secondly, on main drive shaft, manufacture protruding thorn point, and on main drive shaft and driven shaft, increased the elasticity pressure roller, guaranteed the synchronous of picture everywhere displacement, the picture sideslip has all been avoided in these measures, and drive mechanism and general lamp box are basic identical.In order better to control lamp box, time switch and light-operated switch can be installed, it is fully utilized.Motor drives main drive shaft by gear train and rotates during use, goes up and can not move because picture is pressed in the protruding thorn point of main drive shaft by pressure roller, and picture turns over equably synchronously, change the new picture of a width of cloth after, a period of time of stop setting, the new picture of rotational transform again.

Claims

1, the convertible lamp box of storage type picture, it is made up of casing, motor, speed reduction unit, picture, fluorescent tube and gear train, it is characterized in that: unexpanded picture is box stacked the depositing of accordion behind fluorescent tube (7), be carved with protruding thorn point (12) on the main drive shaft (1), on main drive shaft (1) and the driven shaft (10) pressure roller that is close to them (2) is arranged all, the spring (3) that pressure roller (2) is mounted on the lamp box compresses, picture is contained in main drive shaft (1) and driven shaft (10) is upward compressed by pressure roller (2), and main drive shaft (1) couples together by gear train and motor (18).
