Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a TV set support, particularly to a TV set lifter that may adjust the height and visual angle of the TV set. 
       BACKGROUND OF THE INVENTION 
       [0002]    Watching TV is one of the major entertainment activities and information sources for people. With the popularization of LCD TV and plasma TV, the diversification of programs and the increase of channels, people spend more time on watching TV. Watching TV in a fixed position for a long time will make body become uncomfortable and may also lead to some diseases such as scapulohumeral periarthritis, lumbago, cervical spondylosis and sciatica. A TV set lifter can solve these troubles, and enable people to comfortably enjoy rich and colorful TV programs without causing harm on their health. With a TV set lifter, people can remotely or manually adjust the height and visual angle of the TV set according to their visual angle of lying or sitting position, in order to make the TV set be at the optimal visual angle, thereby meeting the requirements for comfortably watching TV. The existing TV set lifters occupy a large space and have poor decorative effect, thus resulting in limitation on their wide application. 
       SUMMARY OF THE INVENTION 
       [0003]    The object of the present invention is to provide a TV set lifter which occupies a small space and has strong decorative effect. 
         [0004]    In order to achieve the foregoing object, the present invention adopts the following technical scheme: a TV set lifter, comprising a guide rail, a guiding component, a TV set support and a lifting mechanism, wherein the guiding component is directly or indirectly connected to the TV set support and the guiding component is coordinated with the guide rail in a rolling or sliding manner. There is a transmission connection between the lifting mechanism and the guiding component and the guide rail includes a panel and two side plates, the lifting mechanism is located in the back of the panel of the guide rail, and the TV set support is located in the front of the panel. 
         [0005]    After the foregoing structure is used, the guide rail has a panel and two side plates, the lifting mechanism is located in the back of the panel of the guide rail and the TV set support is located in the front of the panel, therefore the lifting mechanism is concealed behind the guide rail and achieves the object of occupying small space; further, not only the panel of the guide rail plays a role in covering the lifting mechanism but also its surface may be pasted with various wall paper, plastic paper board, grained board, metal composite paper, aluminum plastic composite panel, marble, decorative tiles, decorative glass, baking varnish or other materials and may also be inlaid with decorative light, clock, thermometer and hygrometer, so it has strong decorative effect and wide applicability and is particularly adapted to household and indoor decoration. Furthermore, the guide rail can be easily processed and shaped. For example, it may be made from a metal plate through folding or plastic through extrusion. It is characterized by low production cost and high carrying capacity, thus is suitable for batch production.
