Description

Changeable picture and text display

Technical field

The utility model relates to advertisement display technique field, specifically a kind of light body, energy-conservation changeable picture and text display.

Technical background

Progress along with society, the propaganda of many commodity and culture is implemented by different medium, for example, TV, broadcasting, Internet network and advertisement boards or the like, these advertisement picture and text propaganda carriers are to be applied to the main media propagated in the last few years, wherein at visible everywhere advertisement boards in public place such as city flooring wall, street, highway, square, parks, can be described as be most widely used, the publicity measures of the economical and practical value of tool.Domestic this series products is mainly based on the rectangle ad promotional plate at present, and much the time can be played propaganda function by day, the advertisement boards that can provide illumination at night again beyond the product of light source light projector be main, outer three faces of beating the lamp formula turn and show screen, the triangular prism display carrier is the aluminium alloy manufacturing, weight is big, the cost height, and especially Projecting Lamp power consumption is higher.Owing to beat the be provided with position of the product of lamp formula to Projecting Lamp outward, the requirement of light efficiency is very strict, limited the size of this series products, and the Projecting Lamp of high flow rate does not meet the requirement of building a conservation-minded society.So existing product not only cost is high but also can't finish curtain-type, the dynamic effect of picture graph text at night such as horse race lamp formula influences and has limited purpose and effect that advertisement is showed.

Summary of the invention

The purpose of this utility model provides a kind of changeable picture and text display that built-in light source is applicable to that round-the-clock advertisement is showed that has.

The purpose of this utility model is achieved in that it includes synchronous motor, synchronous belt, triangular prism display carrier and support framework, it is characterized in that: equidistant parallel is set with outside the row and is set with the central shaft that triangular prism is showed transparent carrier in the support framework, on central shaft, following both ends are provided with respectively with triangular prism shows the axle sleeve that transparent carrier is fixedlyed connected, also be fixedly connected with a synchronous gear on the end axle sleeve therein, this synchromesh gear is connected with synchronous motor by synchronous belt, is offering the cold light lamp light source that triangular prism is showed the transparent carrier illumination near also being provided with row on the central shaft.

The utility model is in order to improve the night illumination effect, and then a side is fixedly connected with reflector with central axes on central shaft, and cold light lamp is fixedly installed on the reflector; This reflector cross section is parabola shaped structure.

The utility model also holds its shape under situations such as temperature variation and external force effect for the triangular prism display carrier, then on central shaft, be set with a shaft shoulder, between the shaft shoulder and axle sleeve, be provided with one and show that to triangular prism transparent carrier provides the tension spring of axial tensile force near the lower end axle sleeve.

The reflector that the utility model adopts and the structure of built-in cold light lamp light source make product can realize good illuminating effect at night, add the dynamic fit of triangular prism displaying transparent carrier, can satisfy different advertisements and show requirement, give unlimited aesthetic feeling; And the employing of tension spring makes the serviceable life that use outward appearance of the present utility model is more attractive in appearance, prolonged product again; The utility model also possesses advantages such as weight is little, cost is low, power consumption is little, the particularly design of lightweight construction, reduced the work high above the ground difficulty, its construction and maintenance product more in the past are more easy, with compare to beat lamp three turning display screens outward, under the uniform more prerequisite of picture brightness, the night illumination power consumption can be saved more than 60%.
