Description

Frame structure and picture installation device of large-scale bill-board

Technical Field

The invention relates to the technical field of billboards, in particular to a frame structure and a picture mounting device of a large-scale billboard.

Background

Nowadays, large-scale advertisement boards and large-scale lamp boxes are widely applied in various fields, and have great ornamental value and high commercial value. Whether public welfare propaganda or commercial advertisement, the large-scale advertisement billboard and the large-scale lamp box are clear and striking, and are beautiful scenic scenes in cities.

Due to frequent replacement of the pictures, the removal and installation of the pictures also become an essential process. The traditional picture mounting process adopts picture buckling and rope threading to enhance the tensile capacity of a picture, and uses metal binding wires, ropes, nylon binding tapes and the like to tighten and mount the picture. Because most advertising display boards and lamp house front end edge position all have the buckle limit of metal or other materials to decorate, when the picture is demolishd and is installed, will detain the limit decorative board and all dismantle, then can go on, the loaded down with trivial details operation of step. Due to frequent replacement, the edge decorative plate is frequently disassembled and assembled, certain damage can be caused to the decorative plate and the internal framework when the number of times is increased, the probability of looseness and falling is greatly increased, and great safety risk is realized. And the construction time is long and the efficiency is low. The flatness of the picture can not be guaranteed, the installation is not easy to be smooth, and wrinkles are easy to generate. The picture is not beautiful, and the picture is not uniformly stressed and is more easily torn locally when meeting high wind pressure due to the fact that the picture is installed completely by hand feeling, and damage is caused.
