Abstract
The utility model provides a point contact turntable base, including try to get to the heart of a matter, quotation, holder, ball, center buckle, be provided with the spacing hole of ball on the holder, place the holder in trying to get to the heart of a matter, place the ball spacing downthehole at the ball, detain the quotation on trying to get to the heart of a matter again, through the center detain will try to get to the heart of a matter and the quotation equipment fixed, can effectively reduce area of contact, the reducing wear dust reduces and rotates the noise greatly, the rotary resistance that significantly reduces, it is rotatory more smooth.
Description
Technical Field
The utility model relates to a point contact carousel base belongs to carousel base technical field.
Background
The turntable base is a common part in life, is small enough to be used as the turntable base of a product display cabinet and is large enough to be used as the turntable base of a dining table. The existing turntable base is designed in a surface contact or line contact mode, the internal friction area is large, the rotating noise is large, the rotating resistance is large, more abrasion dust is generated, and the dust is adhered to the balls to cause the rolling resistance of the balls to be increased due to out-of-roundness and unsmooth rotation. Aiming at the problem, a point contact turntable base is designed, and the contact area is greatly reduced in a point contact mode, so that the defects of the existing product design can be greatly overcome.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art, the utility model provides a point contact carousel base.
The technical scheme of the utility model is that:
a point contact turntable base comprises a turntable bottom, a turntable surface, a retainer, a ball and a center buckle; the retainer is provided with ball limiting holes, the retainer is placed in the tray bottom, the balls are placed in the ball limiting holes, the tray surface is buckled on the tray bottom, and the tray bottom and the tray surface are assembled and fixed through the central buckle.
The retainer is provided with a plurality of ball limiting holes for placing balls, and the balls can roll in the ball limiting holes when the turntable rotates.
The holder is provided with a plurality of supporting salient points for supporting the holder, two ends of each supporting salient point are respectively contacted with the surface of the disk bottom, and the supporting salient points are used for realizing point contact to reduce the contact area and reduce series problems caused by friction.
The edge of the retainer is provided with a plurality of edge salient points which are used for limiting the position of the retainer in the turntable and preventing the retainer from shaking and shifting; meanwhile, the contact area is reduced through point contact design, and series problems caused by friction are reduced.
The utility model has the advantages that:
the point contact turntable base of the utility model can effectively reduce the contact area, greatly reduce the abrasion dust and reduce the rotation noise; the rotation resistance is greatly reduced, and the rotation is smoother.

Detailed Description
The present invention will be further described with reference to the following examples and drawings, but is not limited thereto.
As shown in fig. 1-4.
A point contact turntable base comprises a turntable bottom 1, a turntable surface 2, a retainer 3, balls 4 and a center buckle 5; the retainer 3 is provided with a ball limiting hole 8, the retainer 3 is placed in the disc bottom 1, the balls 4 are placed in the ball limiting hole 8, the disc surface 2 is buckled on the disc bottom 1, and the disc bottom 1 and the disc surface 2 are assembled and fixed through the center buckle 5.
The retainer 3 is provided with a plurality of ball limiting holes 8 for placing the balls 4, and the balls 4 can roll in the ball limiting holes 8 when the turntable rotates.
The retainer 3 is provided with a plurality of supporting salient points 6 for supporting the retainer 3, two ends of each supporting salient point 6 are respectively contacted with the disc surface 2 of the disc bottom 1, and the supporting salient points 6 realize point contact to reduce the contact area and reduce series problems caused by friction.
A plurality of edge salient points 7 are arranged on the edge of the retainer 3 and used for limiting the position of the retainer 3 in the turntable and preventing the retainer from shaking and shifting; meanwhile, the contact area is reduced through point contact design, and series problems caused by friction are reduced.
