Description

TV set rack

Technical field

The present invention relates to a kind of TV set rack, particularly the TV set rack at can regulate visual angle.

Background technique

Along with popularizing of LCD TVs, plasm TV, people are more and more higher to the requirement of the TV set rack at can regulate visual angle.The TV set rack at can regulate visual angle generally comprises angle demodulator and level angle regulator up and down, with the convenient visual angle of regulating TV set rack.Existing TV set rack complex structure with can regulate viewing function, the assembling difficulty, stressed unreasonable, it is big to take up room, and decorative effect is poor, has limited extensive use.

Summary of the invention

The object of the present invention is to provide a kind of simple in structure, be convenient to assemble, stressed rationally and the little TV set rack of volume.

In order to achieve the above object, the technical solution used in the present invention is: a kind of TV set rack, comprise pedestal, intermediate, TV bracket, angle demodulator and level angle regulator up and down, wherein pedestal and intermediate are hinged, TV bracket comprises balance staff and connecting plate, connecting plate is fixedlyed connected with balance staff, intermediate passes through last by first housing and second housing, following link arm is formed by fixedly connecting, the motor of angle demodulator is contained in first housing of intermediate up and down, the motor of level angle regulator is contained in second housing of intermediate, angle demodulator also comprises crank and the connecting rod that is hinged up and down, connecting rod and pedestal are hinged, the level angle regulator also comprises crank and the connecting rod that is hinged, the balance staff of connecting rod and TV bracket is in transmission connection, on, have bearing on the following link arm, the balance staff and the bearing of TV bracket are rotatably assorted.

Rotate for the ease of the band balance staff, have rocking arm on the balance staff of described TV bracket, rocking arm is stretched in the interval between first housing and second housing, the connecting rod of level angle regulator stretch out second housing enter at interval in and hinged with rocking arm.

Frictional force when rotating in order to reduce balance staff also is equipped with plane bearing on the balance staff of described TV bracket, plane bearing is clipped between the upper-end surface of bearing of the lower end surface of rocking arm and following link arm.

In order further to save the space, the described shaft extension of the motor of angle demodulator up and down goes out first housing, and in the interval of crank between first housing and second housing, the rounded end of connecting rod and crank is positioned at interval.

In order to increase housing rigidity and to be convenient to assembling, described first housing and second housing all are flute profile and the notch position has corresponding through hole, and a hinging supporting shaft passes through hole, and the two ends and the hinged-support on the pedestal of hinging supporting shaft are hinged.

For the ease of DTV STB is installed, the Set Top Box frame also is equipped with in the balance staff upper end of described TV bracket.

For the ease of dispelling the heat and alleviating case weight, all have some vent holes on first housing of described intermediate and second housing.

For dustproof, the upper and lower end of described first housing and second housing also is connected with dust cover.

Electric wire for the ease of television set is pegged graft, and on the described dust cover electrical socket is housed.

After adopting said structure, because TV bracket comprises balance staff and connecting plate, connecting plate is fixedlyed connected with balance staff, so TV bracket is simple, and volume is little; Because intermediate is formed by fixedly connecting by upper and lower link arm by first housing and second housing, the motor of angle demodulator is contained in first housing of intermediate up and down, the motor of level angle regulator is contained in second housing of intermediate, therefore, first housing and second housing of intermediate can be arranged side by side, the length of intermediate is shortened greatly, promptly shortened the distance between pedestal and the TV bracket, saved the space, in addition, angle demodulator and level angle regulator are convenient to assembling up and down, do not disturb mutually; Again owing to angle demodulator and level angle regulator all adopt crank and bar linkage structure up and down, has bearing on the upper and lower link arm, the balance staff and the bearing of TV bracket are rotatably assorted, this not only simplifies the structure, reduced volume, and angle demodulator adopts crank, bar linkage structure stressed more reasonable than the gear transmission structure of prior art, and it is easier to make.Bigger motor comes actuation gear because prior art will adopt power, so the volume of required motor is big, and it is big that the volume of the intermediate of dress motor is also wanted.The present invention can adopt lower-powered motor to drive crank, connecting rod, so motor volume is little, thereby has reduced the volume of intermediate; The present invention is ornamental strong in addition, especially is adapted to interior decorations such as family, meeting, classroom and uses.
