Abstract

The utility model discloses a rotational base frame of the TV set, which can freely rotate the TV set in arbitrary angle. The rotational base frame of the TV set is mainly composed of an upper plate (1), a lower plate (2) and a ball (5) between the upper plate (1) and the lower plate (2). Three or more than three spherical surface grooves (4) are arranged in a same circumference of the upper end surface of the lower plate (2), each spherical surface groove is provided with a ball, and an annular notch (6) corresponding to the ball (5) is arranged in the lower end surface of the upper plate. The upper plate (1) can rotate relative to the lower plate (2) through the ball (5). The rotational base frame of the TV set is mainly used for placing the TV set, and the rotational base frame of the TV set can also used as a domestic temporary rotary dining table.

Description

Rotational base frame of TV set

The utility model relates to a kind of rotation platform, specifically a kind of rotating base of placing television set.

Television set in the family generally is to be placed on a fixing position.But in different occasions, beholder's position is different, therefore just is necessary to adjust the angle of television set, so that guarantee best viewing effect and protection beholder's eyesight.Putting picture recording, change antenna or doing other time spent, need to use the interface of television set back or side, will feel very convenient if can at an easy rate television set be rotated to an angle this moment.But also not having at present can be for the device of television set rotation.

Task of the present utility model provides a kind of rotating base of placing television set, and it can rotate television set arbitrarily angled easily.

Finishing solution of the present utility model is: the television set rotating base that is provided is made up of last dish, lower wall and the ball between upper and lower dish.At least be evenly equipped with three spherical grooves on the same circumference in the lower wall upper surface, in the lower surface of last dish, have one with the relative toroidal cavity of each spherical groove of lower wall, each ball places respectively in the spherical groove of lower wall, and contacts with last disc-annular shape groove.Television set is placed on the upper surface of dish.When applying a moment for last dish, on coil relative to ball and rotate.Be that ball slides in the spherical groove of lower wall, the annular groove of going up dish simultaneously again relatively rolls.Because lower wall is fixed, therefore last dish will drive television set and rotate together.

For the stationarity that guarantees television set when rotation and reduce manufacturing cost, the spherical groove of lower wall preferably only is provided with three.

The utility model can be arbitrarily angled with the rotation of television set original place easily, and help the protection against the tide and the heat radiation of television set.Owing to adopted upper and lower dish structure, and utilize ball as the counterrotating actuated element of upper and lower dish, not only simple in structure, rotate flexibly, steadily, and the height dimension of base is very little, therefore can be placed on the existing cabinet for TV table top with television set very easily.In addition, the utility model also can be used as the interim rotary dining table of family expenses.

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is an another kind of structure chart of the present utility model.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

As shown in Figure 1: on coil 1 and lower wall 2 for discoid, adopt aluminium alloy to make.For economical with materials, weight reduction, upper and lower dish middle part has a plurality of holes.The slightly larger in diameter of upper and lower dish is in the width of television set bottom surface.There are three legs 3 bottom surface of lower wall 2, and three spherical grooves 4 are arranged above it, and they are 120 ° to the angle between the line of following disk center, places a ball 5 in each groove.There is an annular groove 6 bottom surface of last dish 1, and the diameter of groove 6 equals the distribution circle diameter of lower wall groove 4, corrects on the ball 5 to be positioned among the groove 6.The degree of depth of groove 6 should guarantee between the upper and lower dish certain clearance is arranged.Therefore, coiling 1 on can rotate relative to lower wall 2 by ball 5.After on television set is put into, coiling,,, can rotate with last dish as long as touch a jiao of television set owing to have frictional force between them.Yet for convenience with for the purpose of the safety, the edge that is preferably in dish is provided with a handle 7.

Another kind of structure of the present utility model as shown in Figure 2.The edge of last dish 8 extends downwardly into the side of lower wall 9, there is a position fixing handle 10 its extension, it by hollow handle 11, pass handle 11 and its front end can insert lower wall 9 location hole 12 pin 13 and be contained in the handle 11 and the stage clip 14 that forces in pin 13 is formed.Transfer to pin 13, then upper and lower dish separates, on coil 8 free to rotate.Unclamp pin 13, pin 13 inserts in the lower wall location hole 12 under the effect of stage clip 14, and upper lower burrs is combined as a whole.Can make its location after transfering to pin 13, can along it two alignment pins 15 be set axially at the head of pin 13, they can insert in the hole 16 of handle 11 ends.After transfering to pin 13,, make alignment pin 15 be bearing in atresia place, handle 11 end and get final product as long as rotate pin 13.Above-mentioned leg 3 also can adopt adjustable foot, and rotary screw 17 can be adjusted the level of rotating seat.

Claims

1, a kind of television set rotating base, it is characterized in that forming by last dish 1,8, lower wall 2,9 and the ball 5 between upper and lower dish, at least be evenly equipped with three spherical grooves 4 on the same circumference in the lower wall upper surface, in the lower surface of last dish, there are toroidal cavity 6 each balls 5 relative to place respectively in the spherical groove 4 of lower wall, and contact with last disc-annular shape groove 6 with each spherical groove of lower wall 4.

2, rotating base as claimed in claim 1, the spherical groove that it is characterized in that said lower wall 2,9 is three.

3, rotating base as claimed in claim 1 or 2 is characterized in that being provided with handle 7,10 at the edge of last dish 1,8.

4, rotating base as claimed in claim 3, it is characterized in that handle 10 by hollow handle 11, pass handle 11 and its front end can insert lower wall 9 location hole 12 pin 13 and be contained in the handle 11 and the stage clip 14 that forces in pin 13 is formed.
