Pre-maintaining mechanism of screen

Abstract

The invention relates to a pre-maintaining equipment of a screen, in particular to a pre-maintaining mechanism of the screen. The pre-maintaining mechanism comprises a first supporting frame, a second supporting frame, a first cross arm and a second cross arm, wherein an arm groove is arranged at the middle part of the first cross arm along a radial direction; the middle parts of the first cross arm and the second cross arm are crossly and rotatably connected through an overturning sliding structure mounted on the arm groove; one opposite ends of the first supporting frame and the second supporting frame are provided with sliding grooves; one ends of the first cross arm and the second cross arm are respectively mounted on the sliding grooves through stretching sliding structures; and the other ends of the first cross arm and the second cross arm are mounted at the other ends of the second supporting frame and the first supporting frame. According to the pre-maintaining mechanism of the screen, a simple cross structure is utilized and a stretching mechanism and an overturning mechanism are combined, so that the stretching movement and the overturning movement can be realized simultaneously and the maintenance of the screen is greatly convenient; and the structure is simple and the cost is low.

Description

technical field [0001] The invention relates to screen front maintenance equipment, in particular to a screen front maintenance mechanism. Background technique [0002] At present, LCD wall-mounting is more and more widely used in the electronics industry, and there are various installation methods of wall-mounting, such as vertical cabinet type, wall-mounted type, etc. The installation method of wall-mounting directly affects the maintenance method of LCD, which is generally divided into Pre-maintenance and post-maintenance. In some applications where the space is relatively limited, it is generally necessary to maintain the LCD video wall from the front. [0003] There are many kinds of commonly used front maintenance mechanisms, such as guide rail telescopic, cross telescopic, etc., and some telescopic and then flipped modes. However, the current extension adjustment and flip adjustment are all realized by independent mechanisms, that is to say, generally need to be rea...

AI Technical Summary

Problems solved by technology

However, the current extension adjustment and flip adjustment are all realized by independent mechanisms, that is to say, generally need to be realized by two mechanisms, the structure is more complicated, and the adjustment is inconvenient, and the existing extension and flip mechanisms are combined Together, there are disadvantages such as complex structure and high cost
