Lamp box frame structure

Abstract

The invention belongs to the technical field of lighting or advertising lamp box lamp structural design, and particularly relates to a lamp box frame structure. The structure comprises a mounting shell plate, a quick-release pressing strip, a transparent panel and a quick-release assembly; the mounting shell plate comprises a plate body, and rotating shaft holes are formed on the left and right inthe front side of the plate body; a pin cap mounting screw hole is formed in the rear side of the quick-release pressing strip; the lower end of the sealing pressing plate is hinged in the rotating shaft holes; and the quick-release assembly comprises a metal ejector pin arranged in an ejector pin mounting screw hole, a pin cap arranged in the pin cap mounting screw hole, and a plurality of magnetic steel balls, a balance ring and a spring which are arranged between an ejector pin and a pin cap. According to the lamp box frame structure, the built-in quick-release assembly is adopted for connection and fixation; and the lamp box frame structure can effectively prevent the influence of external force operation, the problems of thread slipping, abrasion and the like existing in threaded connection cannot be generated during disassembly and assembly, when disassembly is needed, a strip-shaped magnet is used for adsorption operation, and the elastic steel balls move towards the front side, so that the ejector pin can be separated from the pin cap.

AI Technical Summary

Problems solved by technology

[0002] Frame-type box-type lamps are lighting or supporting equipment often used in various commercial advertisements, wall beautification and other occasions. Traditional light box structures are generally assembled and used with lightweight frames and bolted or cemented. Old-fashioned light boxes that need to be replaced and maintained or replaced with corresponding promotional materials, due to frequent disassembly and use, the structure of the light box is loose. Since such light boxes for publicity are generally installed in places with a large flow of people, such as stations and subways, they are more likely to be used by others. Touching or operating, under the influence of various factors, the structure of this kind of lamps is often and easily damaged or even maliciously demolished, causing the equipment to lose its function. The impact is more serious, further reducing the performance and life of the product
