Abstract
The utility model relates to a double-sliding-rail type lifting supporting frame for a display screen. The double-sliding-rail type lifting supporting frame comprises a base and a fixed support arranged on the base, and is characterized by further comprising a lifting sliding block and two sliding guide rails, wherein the lifting sliding block is capable of lifting and moving on the fixed support, and the two sliding guide rails are arranged on the fixed support in parallel. The lifting sliding block is arranged on the fixed support through the sliding guide rails and capable of moving vertically along the sliding guide rails. The lifting sliding block is provided with an ejection rod, one end of the ejection rod is fixedly connected with the lifting sliding block, the other end of the ejection rod is connected with the fixed support through a tension spring, and the ejection rod is shorter than the fixed support. According to the double-sliding-rail type lifting supporting frame, the left sliding guide rail and the right sliding guide rail are arranged on the inner face of the fixed support in a disperse mode, and therefore spans and resisting arms of stress fulcrums are large; in addition, the sliding rails have strength, the disperse fixed arrangement enables the sliding rails to get additional reinforcement, therefore, stress situations are further improved, and rigidity is improved. When the double-sliding-rail type lifting supporting frame is subjected to external force, shake ranges and shake time of the display screen are reduced, meanwhile, the advantages of being light and ultrathin of an original support are maintained, and the double-sliding-rail type lifting supporting frame is simple, easy to realize, and obvious in effect.
