Description

Lifting and rotating mechanism

technical field

The utility model relates to an elevating and rotating mechanism, in particular to an elevating and rotating mechanism used in a wall-mounted flat-panel display, which can move the flat-panel display up and down or rotate smoothly, smoothly and naturally, and has a better mobilization space effect, It has the advantages of simplification and easy operation, and does not take up too much space in the room, which can effectively save space.

Background technique

With the rapid development of today's electronic technology and the improvement of living standards, traditional CRT displays have gradually been replaced by popular flat-panel displays, such as liquid crystal displays, liquid crystal televisions (LCD) or plasma televisions. (PDP) and so on; and because the current flat-panel display has the characteristics of lightness, thinness, high mobility, can be hung on the wall and does not occupy space in terms of volume design, and at the same time, it is becoming more and more functional in design. More and more powerful, therefore, has become the mainstream product of the current display.

However, in order to obtain the best viewing angle for a general vertical flat display, a pivot structure is usually pivoted between the body of the display and its base, such as: composed of hinges (Hinge) on both sides, so that The display body can have the function of adjusting front and rear elevation angles relative to the base.

Furthermore, as the environment changes and based on space requirements, the environments where flat-panel displays are installed are more diversified, such as: display walls, partition systems in office spaces, or environments in public open spaces (such as hospitals) , and with the design of some environments, the flat-panel display also adopts a hanging method, which usually uses two ends of a bracket structure, which are respectively combined on the back of the flat-panel display and fixed on the wall, and then through the bracket structure. The pivot mechanism enables the flat panel display to perform multi-angle rotation adjustment with the pivot mechanism as the axis.

However, the existing brackets and rotating mechanisms all imply imperfections in structural design or in actual use, resulting in the following defects:

1. The assembly components of existing brackets and rotating mechanisms are often too complicated in design, resulting in a sharp increase in the maintenance and manufacturing costs of the brackets and rotating mechanisms. In today's low-profit market environment, the industry will lose a lot of market competitiveness.

2. Due to the mechanical design relationship of the pivot mechanism of the existing bracket and the rotation mechanism, the rotation adjustment cannot be carried out smoothly, smoothly and naturally. This relatively causes the flat panel display to be easily shaken due to the rotation adjustment. Such a transfer method will inevitably have a negative impact on the precision electronic equipment of the flat-panel display. A little carelessness may cause defects in the flat-panel display, and unstable images and quality may occur.

3. The existing bracket must be adjusted and rotated, so the length of the bracket is long and the assembly width is also large, resulting in a large indoor space and location, and affects the pedestrian's action space. For the limited indoor space, it will definitely affect the indoor furniture. And the placement of utensils, it can't save space, which is quite troublesome and inconvenient.
