Lifting mechanism for LCD display screen holder of exhibition vehicle

Abstract

A lifting mechanism for an LCD frame of an exhibition car belongs to the technical field of exhibition vehicles. The lifting mechanism comprises a pair of hoisting devices which are corresponding to each other and arranged on a platform floor of the exhibition car, the pair of the hoisting devices are fitted with a hoisting frame in a sliding manner respectively; one of the hoisting devices is fixed with the lower part of an end along the length direction of the LCD frame of the exhibition car, and the other hoisting device is fixed with the lower part of the other end along the length direction of the LCD frame of the exhibition car. The lifting mechanism has the advantages that by hoisting or lowering the hoisting frame with the hoisting devices, the LCD frame is hoisted or lowered along with the hoisting frame, thus meeting the requirement of freely lifting the LCD frame; the pair of hoisting frames has good holding effect on the LCD frame and can ensure the rigidity of the LCD frame to avoid swing which affects the exhibition in the course of exhibition.

Description

technical field [0001] The invention belongs to the technical field of display vehicles, and in particular relates to a lifting mechanism for a liquid crystal display frame of a display vehicle. Background technique [0002] Display cars are called mobile advertisements, and their applications are becoming more and more frequent and extensive. For example, they are used by merchants to promote products, or by manufacturers to promote products, and for some large-scale events. pre-planning or real-time display, etc. [0003] The display car is usually equipped with a liquid crystal display, and the liquid crystal display is arranged on the liquid crystal display frame, and the liquid crystal display frame is fixed with the vehicle. Yet because the liquid crystal display frame of the display vehicle in the prior art is fixed, can not be lifted as required, and only its bottom is fixed with the vehicle, thus bringing the following technical problems: one is easy to produce lat...

AI Technical Summary

Problems solved by technology

Yet because the liquid crystal display frame of the display vehicle in the prior art is fixed, can not be lifted as required, and only its bottom is fixed with the vehicle, thus bringing the following technical problems: one is easy to produce lateral swing under the display state, It not only affects the display effect, but also has safety, especially in the case of large external wind power series, due to the lack of rigidity of the LCD display frame, it cannot resist the lateral resistance and can only disable the LCD display; the second is the screen of the LCD display. It is small and limited in height, which affects the effect of publicity. If it is to appear in the form of a large screen and obtain the expected height, then it is difficult for the LCD stand to be used as a backing
