Description

The rotary seat of display

Technical field

The utility model relates to a kind of display, relates in particular to a kind of rotary seat that can conveniently rotate the display of use that has.

Background technology

As shown in Figure 1, the base of existing display mainly is made of with rotating disk 200 chassis 100; Wherein, top formation one cancave cambered surface 101 on chassis 100 is taken over a business 200 bottom surface and is formed a convex globoidal 201 corresponding to chassis 100 cancave cambered surfaces, 101 curvature, makes the convex globoidal 201 of rotating disk 200 just can be positioned on the cancave cambered surface 101 on chassis 100; 200 of chassis 100 and rotating disks are combined by a rotating shaft 300.Whereby, though what display 400 can be firm is positioned on the base, and make angle and rotate, but because the convex globoidal 201 of rotating disk 200 is cancave cambered surface 101 curvature corresponding to chassis 100, therefore when the convex globoidal 201 of rotating disk 200 is positioned on the cancave cambered surface 101 on chassis 100, the convex globoidal 201 of rotating disk 200 and the cancave cambered surface 101 on chassis 100 are into contacting of face and face; When display 400 when adjusting angle, the contact friction of the convex globoidal 201 of rotating disk 200 and cancave cambered surface 101 formation faces with the face on chassis 100, thereby produce great frictional resistance, and then cause the inconvenience in the use.

The utility model content

In order to overcome the above-mentioned shortcoming that existing display base exists, the utility model provides a kind of rotary seat of display, and it has the advantage that can conveniently rotate use.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of rotary seat of display is characterized in that, comprises chassis, rotating disk, ball dish, rotating shaft and a plurality of roller; The chassis, its central authorities form first card that raises up, and chassis outer rim formation one is lower than second card of first card, and this first card is provided with a circular ball grooves, and central authorities are provided with an axis hole; Rotating disk also is provided with a circular ball grooves on the card corresponding to the ball grooves on chassis, and card central authorities are provided with an axis hole; The ball dish is provided with a plurality of circular holes corresponding to the card of the ball grooves of chassis, rotating disk, each ccontaining ball of circular hole, and the first half of ball is placed in the ball grooves of rotating disk, and the first half of ball is placed in the ball grooves on chassis, and the central authorities of ball dish are provided with an axis hole;

Rotating shaft, it passes through the axis hole on rotating disk, ball dish and chassis from top to bottom respectively, and chassis, rotating disk and ball dish are combined into a rotary seat;

A plurality of rollers are evenly distributed in the rotating disk card below of second card on corresponding chassis by a roller mount, roller contacts with second card on chassis.

The beneficial effects of the utility model are,

The utility model directly is positioned over the function of the enterprising enforcement usefulness of rotating disk card except having existing screen display, also can on the rotating disk card, articulate a support, to use as the LCD base, can reduce spin friction resistance between chassis and rotating disk by the ball on the ball dish, make rotating disk be able to rotate more flexibly; Simultaneously, be evenly distributed in the outer rim card on chassis and the rotating disk card below corresponding by a plurality of rollers, but and the loaded area of expansion chassis and rotating disk and raising bearing weight has the advantage that more convenient rotation is used with it.

Embodiment

As shown in Figure 2, the utility model comprises a chassis 10, rotating disk 20, ball dish 30, rotating shaft 40 and a plurality of rollers 50; Wherein:

Chassis 10 (please consulting shown in Figure 3 simultaneously), its central authorities form first card 11 that raises up, and the outer rim that makes chassis 10 forms second card 12 that is lower than first card 11, and this first card 11 is provided with a circular ball grooves 13, and central authorities are provided with an axis hole 14.

Rotating disk 20 (please consulting shown in Figure 3 simultaneously) also is provided with a circular ball grooves 21 on its card corresponding to the ball grooves 13 on chassis 10, card central authorities are provided with an axis hole 22.

Ball dish 30 (please consulting shown in Figure 3 simultaneously), its card corresponding to the

ball grooves

13,21 of chassis 10, rotating disk 20 is provided with a plurality of circular hole 31, and in circular hole 31 each ccontaining ball 32, the first half of this ball 32 then just can be placed in the ball grooves 21 of rotating disk 20, and the first half of ball 32 just can be placed in the ball grooves 13 on chassis 10, and the central authorities of ball dish 30 are provided with an axis hole 33.

Rotating shaft 40 (please consulting shown in Figure 3 simultaneously), it passes through the axis hole 14,22,23 on rotating disk 20, ball dish 30 and chassis 10 from top to bottom respectively, and chassis 10, rotating disk 20 are combined to form a rotary seat with ball dish 30.

A plurality of rollers 50 (please consulting shown in Figure 3 simultaneously), it is each rotating disk 20 cards below that is evenly distributed second card 12 of being located at corresponding chassis 10 by a roller mount 51, roller 50 contacts with second card 12 on chassis 10.

By said structure, the utility model except existing screen display 60 directly can be placed on rotating disk 20 cards use (as shown in Figure 4), and also can on rotating disk 20 cards, articulate a support 70, make LCD 80 use (as shown in Figure 5) as base; Because chassis 10 of the present utility model and 20 clampings of rotating disk, one ball dish 30, ball 32 on the ball dish 30 forms point and contacts with

chassis

10,20 of rotating disks, therefore can reduce the spin friction resistance of 20 of chassis 10 and rotating disks, and rotating disk 20 can be rotated more flexibly; Simultaneously, be evenly distributed in second card 12 on chassis 10 and the rotating disk 20 cards below corresponding by a plurality of rollers 50 with it, but therefore can enlarge the loaded area of chassis 10 and rotating disk 20 and improve load capacity, and then the display rotary seat that provides a more convenient rotation to use.

From the above and embodiment shown in the drawings as can be known, technological means that the utility model used and structure thereof really can reach the purpose of its creation, and provide a display rotary seat that has more practicality and progressive, and really unprecedented, meet novel patent requirement, so file an application in accordance with the law.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
