Ultrahigh connecting piece for three-sides billboards

Abstract

The invention discloses an ultrahigh connecting piece for three-sides billboards. The ultrahigh connecting piece comprises an upper connecting-piece triangle, a lower connecting-piece triangle, an upper light bar connecting piece and a lower light bar connecting piece, a first bearing block and a first bearing are arranged in the center of the upper connecting-piece triangle; a second bearing block and a second bearing are arranged in the center of the lower connecting-piece triangle, the upper light bar connecting piece is arranged in the first bearing, the lower light bar connecting piece isarranged in the second bearing, and the upper light bar connecting piece is fixedly connected with the lower light bar connecting piece. The bearing blocks are integrally designed in cavities of theupper and lower connecting-piece triangles, design of special bearing blocks is omitted, overall vertical height of the connecting piece is greatly lowered, and 'black tape' situation at the intermediate junction of the large-scale billboards is greatly reduced visually; weight is reduced, and production cost is lowered; the upper and lower light bar connecting pieces and the upper and lower connecting-piece triangles are provided with connecting parts, and the connecting parts are designed to be structural styles with direct splicing; the ultrahigh connecting piece is simple in overall structure and convenient and rapid in installation.

Description

technical field [0001] The invention relates to a three-side billboard, in particular to a connecting piece of a three-side billboard. 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. [0003] The existing three-sided billboard is tr...

Problems solved by technology

[0004] Based on the above, the technical problem to be solved by the present invention is to propose a structure that is simpler, lighter in weight and lower in manufacturing cost in view of the shortcomings of existing ultra-high connectors with relatively complex structure, heavy weight and slightly higher manufacturing cost. Reasonable connection, ultra-high connectors that are convenient for promotion and application
