a roll up banner

Abstract

The invention relates to a roll up banner. The roll up banner is composed of a shell body, a tension spring, a supporting rod and bottom feet, wherein the shell body is internally provided with the tension spring; a supporting rod is inserted into the middle position at the upper part of the shell body; the bottom feet are symmetrically mounted at the lower part of the shell body; the roll up banner is characterized in that the shell body comprises an upper cover and a collet buckled at the lower part of the upper cover; an upper mounting groove and a lower mounting groove are formed in two side walls of each of the upper cover and the collet, the upper mounting groove and the lower mounting groove are buckled to commonly form a tension spring mounting opening for mounting the tension spring; a picture expansion opening is formed in a joint of the front ends of the upper cover and the collet; a supporting rod mounting opening for inserting the supporting rod is formed in the middle position of the top of the upper cover in an injection molding manner; the bottom feet, which are formed by injection molding, are rotatably mounted at the two ends of the lower part of the collet. The roll up banner provided by the invention is scientific and reasonable in structural design, and has the advantages of high machining efficiency, convenience for assembling, labor and manpower saving, production cost saving, easiness of recycling and beautiful appearance.

Description

technical field [0001] The invention relates to a roll-up display stand, in particular to a roll-up display. Background technique [0002] Roll-up banners, or poster stands, display stands, are stand-up promotional posters. The material of existing roll-up banners is mostly aluminum alloy, and its parts are various, and installation is complicated. That is, it is mainly composed of a shell, a tension spring, a support rod and a foot. The shell is composed of an upper profile, a lower profile, a left gusset and a right gusset connected by screws. During processing, the upper profile and the lower profile need to be cut first, and then processed into the required structure by bending. The upper and lower profiles are limited by their respective slots, and then the left gusset and the right buckle are respectively buckled at both ends. The gusset is fixed by screws, the tension spring is installed between the left gusset and the right gusset, the support rod is inserted into ...

AI Technical Summary

Problems solved by technology

When processing each mounting hole, it is necessary to drill holes at the corresponding positions first, and then manually deburr the mounting holes. The whole process has the disadvantages of low processing efficiency, high labor intensity, and waste of labor.
