Description

A kind of flat-panel television hanging shelf

Technical field

The utility model relates to and a kind of television set is hung on device on the wall body, relates in particular to a kind of device that panel TV hangs that is suitable for.

Background technology

Along with the maturation of technology, be that the panel TV of representative is just progressively popularized with plasm TV, LCD TV.At present, the in actual use modes of putting that adopt of panel TV also have by the wall hanging accessory to hang on the wall body more.Hang helps saving user's space.But existing wall hanging accessory often can only play the effect of installing and fixing, and is about to panel TV and is mounted on a certain ad-hoc location on the wall body, and can't adjust, change the angle between video screen and the wall body, is difficult to satisfy the needs that the user watches.

The utility model content

Technical problem to be solved in the utility model provides a kind of flat-panel television hanging shelf that can adjust quickly and easily, change the angle between video screen and the wall body.

The technical scheme that its technical problem that solves the utility model adopts is: flat-panel television hanging shelf of the present utility model, comprise the substrate that forms a fixed connection by connector and wall body, it is characterized in that: respectively be provided with one four bar swing mechanism on the left and right two ends of described substrate; Described four bar swing mechanisms are made of pedestal, rocking arm and two spiral arms, described pedestal is connected with substrate, the lower end of described rocking arm is connected with the pedestal hinge by bearing pin, the upper end of a spiral arm is connected with the pedestal hinge by bearing pin in the described spiral arm, and the upper end of another spiral arm is connected with the rocking arm hinge by bearing pin, and the lower end of these two spiral arms connects by the pin hinge that has damping element on it.

During use, panel TV is fixed on the described rocking arm, can be at the effect lower shake-changing arm of external force around the pedestal lower end with respect to wall body deflection certain angle, thus can adjust, change the angle between video screen and the wall body easily.After described damping element makes and adjusts to the right place, can keep the relative position of described rocking arm and pedestal, and can make described four bar swing mechanisms form slow-action in adjustment process, the impact of avoiding producing because of overexerting causes damage to panel TV.

As improvement of the technical scheme, for making wall hanging frame overall structure of the present utility model more compact, the cross section of described rocking arm and two spiral arms is all in the form of slot, and when described rocking arm was parallel with wall body, two spiral arms were rugosity and are folded in the space that described rocking arm and pedestal constitute.

As further improvement in the technical proposal, panel TV forwards ultimate angle to quickly when adjusting in order to avoid, and describedly two spiral arm lower ends is formed also be set with torsion spring on the hinged bearing pin, and the two ends of described torsion spring are connected with one of them spiral arm respectively.Rotating flatly when analysing TV, torsion spring produces counter-force upwards, prevents that panel TV from forwarding ultimate angle to quickly; When making progress the pivotal plate TV, torsion spring produces power upwards and offsets a part of gravity, makes to adjust to become light.In addition, at the time of emergency, when damping element lost efficacy as described, when can also preventing that panel TV from rotating with higher speed, torsion spring, played the effect of protecting panel TV to panel TV the impacts infringement of etc.ing.

The beneficial effects of the utility model are, can adjust, change the flat-panel television hanging shelf of the angle between video screen and the wall body quickly and easily, can realize panel TV with respect to mounting plane around trunnion axis or vertical axis rotating freely in the certain angle scope, have better operability and security reliability, especially be suitable for the suspension of big screen panel TV.
