Abstract
The utility model discloses a rotation mechanism for support of the liquid crystal television, comprising a bottom plate, a rotatable press plate connected with the bottom plate through a rotary central axis, a mounting frame vertically connected to the press plate, wherein a plurality of mounting pores are provided on the vertical mounting plate of the mounting frame, and at least two pinch rollers contacting edge of the press plate are disposed on peripheral of the press plate. Comparing with prior rotation mechanisms, the utility model is simple in construction, low in cost, of moderate torsion, thus easy to rotate, stable and reliable without shake. Face rotation is adopted, and detect of unstable rotation of single axis is avoided.
Description
Technical field
The utility model relates to rotatable mechanism, more particularly, relates to a kind of rotating mechanism that is used for the LCD TV machine base.
Background technology
The birth of liquid crystal TV set has brought a kind of new seeing and hearing enjoyment for people's life.LCD TV has been compared its advantage with conventional picture tube (CRT) TV: picture is stable, image fidelity, elimination radiation, save the space, save energy consumption, life-saving.But liquid crystal TV set is compared with conventional picture tube (CRT) TV and is existed visible angle to cross minor issue.Angle of visibility stands in about screen center's line, still can clearly see the angular range of screen picture during certain position, the left and right sides.The rotatable base of LCD TV is a lot of on the market at present, but generally mainly there are the following problems:
1, reasonable rotating base, the rotating mechanism complexity, cost is too high;
2, the simple rotating base of mechanism exists:
A) instability problem (as: causing the television set double swerve);
B) solve stable problem, can cause rotation torque excessive again, the turn difficulty.
The utility model content
The utility model is the technical problem that will solve the above-mentioned rotating base of available liquid crystal television set existence, a kind of low cost is provided, rotates flexible, reliable and stable rotating mechanism.By the rotating mechanism of base, adjust the visible angle of liquid crystal TV set, so that people obtain best visual enjoyment.
For solving the problems of the technologies described above, the technical solution of the utility model is a kind of rotating mechanism of structure, the rotatable pressing plate that it comprises base plate, be connected with this base plate by a rotary middle spindle, vertically be fixedly connected on mounting bracket on this pressing plate, have a plurality of installing holes on the vertical mounting panel face of this mounting bracket, the periphery of described pressing plate is provided with two pinch rollers that roll and contact with platen edge at least.
In the preferable embodiment of the present utility model, described pinch roller is three, is distributed in the periphery of described pressing plate, and this pinch roller is made by nylon material, and its outer rim is the groove of annular, and the periphery of pressing plate is stuck in the groove of pinch roller.
Wherein, having on the described pressing plate with described rotary middle spindle is the visual angle stopper slot of the circular arc at center, and described base plate is provided with a spacer pin that stretches into the visual angle stopper slot of pressing plate.The bottom of described mounting bracket, pressing plate and base plate are arranged in the plastic casing, and constitute a rotating base.
The utility model is compared with existing rotating mechanism: simple in structure, with low cost; Moment of torsion is moderate, turn is light; Reliable and stable, release is rocked; The rotation of employing face has avoided single shaft to rotate unsettled shortcoming.This mechanism is a kind of economic, practical rotating mechanism.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further, wherein:
Fig. 1 is the stereogram of the utility model preferred embodiment;
Fig. 2 constitutes the schematic perspective view of rotating base for the utility model preferred embodiment.
Embodiment
Fig. 1 shows the basic structure of the utility model preferred embodiment, described a kind of rotating mechanism, it comprise base plate 4 and be positioned at its above 2 can counterrotating pressing plate 2, this pressing plate is connected with base plate by a pivot 5.One mounting bracket 1 vertically is fixedly connected on the pressing plate 2 by screw, has a plurality of installing holes 7 on the vertical mounting panel face of mounting bracket, and the periphery of pressing plate 2 is provided with two pinch rollers 3 that roll and contact with platen edge at least.In the present embodiment, pinch roller 3 is three, is distributed in the periphery of pressing plate 2, and pinch roller is made by nylon material, and its outer rim is the groove of annular, and the periphery of pressing plate is stuck in the groove of pinch roller.The visual angle stopper slot 6 that to have with described rotary middle spindle 5 on the pressing plate 2 be the circular arc at center, base plate 4 are provided with a spacer pin 8 that stretches into the visual angle stopper slot of pressing plate.
As shown in Figure 2, in the bottom of mounting bracket 1, pressing plate 2 and the base plate 4 assembling plastic casings, and constitute a both artistic and practical rotating base 9.Be that base plate 2 is fixed with plastic casing, pressing plate 2 and mounting bracket 1 can rotate relative to base plate 2 (plastic casing).
The mounting bracket 1 of the rotating base 9 that the utility model is made is screwed with the liquid crystal TV set back side and connects, and rotates television set and just can easily obtain needed visible angle.This mechanism can control the maximum anglec of rotation of liquid crystal TV set by visual angle stopper slot 6.In order to prevent that the single shaft instability that causes that is rotatably connected from rocking, increased by four pinch rollers 3, control pressing plate 2 converts it into the face rotation.Pinch roller 3 adopts high-strength nylon to make, and promptly has rigidity can increase rotation torque, and flexible can reduce the friction noise that occurs in the rotation again.This mechanism is a kind of economic, practical rotating mechanism.
Claims (4)
1, a kind of rotating mechanism, it is characterized in that, the rotatable pressing plate (2) that comprises base plate (4), is connected with this base plate by a rotary middle spindle (5), vertically be fixedly connected on mounting bracket (1) on this pressing plate, have a plurality of installing holes (7) on the vertical mounting panel face of this mounting bracket, the periphery of described pressing plate (2) is provided with two pinch rollers (3) that roll and contact with platen edge at least.
2, rotating mechanism according to claim 1 is characterized in that, described pinch roller (3) is three, is distributed in the periphery of described pressing plate (2), and this pinch roller is made by nylon material, and its outer rim is the groove of annular, and the periphery of pressing plate is stuck in the groove of pinch roller.
