Description

Technical Field

[0001] The utility model relates to the technical field of LED light box frames, and particularly relates to an ultra-thin LED light box frame. Background Technique

[0002] Light boxes are mainly used as tools for displaying meeting processes, advertising slogans, and other information that needs to be specially reminded. Currently, the light sources commonly used in light boxes are LED lights. Light boxes usually include vertical, suspended, and side-wall fixed types. The common installation method is to set the light box in a three-dimensional shape. The light box frame is the skeleton of the light box and is usually made of aluminum alloy, stainless steel, or cold-rolled steel plates. Light box frames made of different materials have different service lives, load-bearing capacities, and application ranges. However, the ultra-thin LED light box frames used at present are composed of connecting the frames through corner codes and multiple fixing screws to form a complete ultra-thin LED light box frame, which is time-consuming and laborious and rather troublesome during the installation process.

A threaded rod is movably installed on the inner surfaces of the third bearing and the second bearing. A second umbrella-shaped tooth groove is formed on the surface of the other end of the threaded rod.

[0010] Preferably, the second umbrella-shaped tooth groove formed on the surface of the other end of the threaded rod meshes with the first umbrella-shaped tooth groove formed at the lower end of the rotating rod. A rectangular clamping block is spirally installed on the outer surface of the threaded rod. The rectangular clamping block is slidably installed in the first chute.

[0011] Preferably, rectangular sliding blocks are fixedly installed near the other end on the upper and lower surfaces of the rectangular clamping block. Rectangular sliding grooves are formed on the upper and lower surfaces of the first chute. The rectangular sliding blocks are slidably installed in the rectangular sliding grooves.
