Three-side-turning advertising board prism transmission assembly

Abstract

The invention discloses a three-side-turning advertising board prism transmission assembly. The three-side-turning advertising board prism transmission assembly comprises a support base, an upper transmission central spindle, a lower transmission central spindle, a transmission wheel, a transmission shaft sleeve and a spring, wherein a containing cavity is arranged in the center of the support base; the upper transmission central spindle is arranged on the upper portion of the containing cavity; the lower transmission central spindle is arranged on the lower portion of the containing cavity; the transmission wheel is arranged below the support base and connected with the lower transmission central spindle; the transmission shaft sleeve is vertically arranged along the containing cavity; the upper end of the transmission shaft sleeve is in transmission connection with the upper transmission central spindle; the lower end of the transmission shaft sleeve is connected with the lower transmission central spindle; and the upper transmission central spindle and the lower transmission central spindle are spaced, and the spring is arranged in the space formed by the upper transmission central spindle and the lower transmission central spindle. The transmission shaft sleeve and the spring are additionally arranged, the upper transmission central spindle is downwards pressed, the springis made to be compressed, the upper transmission central spindle moves downwards by a certain distance after the spring is compressed, and thus field assembly and maintenance and replacement when a three-prism advertising board is damaged later are facilitated.

Description

technical field [0001] The invention relates to a transmission mechanism of a three-sided billboard, in particular to a transmission assembly in the transmission mechanism. Background technique [0002] The three-sided billboard originated in Europe and was introduced to China in the 1990s. It consists of a set of triangular prisms positioned side by side. Through PLC controller control, motor drive, and cam transmission, the triangular prism rotates around its own central axis, flips and freezes in different forms and sequences according to the preset methods, and forms three dynamic pictures that change in turn. It can be widely used outdoors, such as on both sides of roads, stations, airports, docks, stadiums, walls and roofs of large buildings, etc., and can also be set up indoors such as exhibition halls, shopping malls, casinos and other places, which can increase the golden advertising At the same time, it can achieve the effect of beautifying the city.
