In the figure: the friction support column comprises an annular seat 1, an annular placing groove 101, an annular cover 2, an annular groove 201, a friction support column placing groove 202, an auxiliary annular groove 203, a friction support column 3, a ball 4 and a circular tube 5.
Detailed Description
As shown in fig. 1 to 9, a preferred solution is a modular desktop rotary core, which includes an annular seat 1, an annular placing groove 101 is provided on the annular seat 1, a plurality of rolling bodies are placed in the annular placing groove 101, an annular cover 2 covers the annular seat 1, an annular groove 201 is provided on the lower surface of the annular cover 2, and the rolling bodies are located between the annular placing groove 101 and the annular groove 201; the upper surface of the annular cover 2 is provided with a plurality of friction support columns 3. The friction support column 3 is used for placing a turntable of a dining table, and the friction support column 3 can be made of rubber or foam materials, and the aim is to increase the friction force between the friction support column 3 and the turntable. The annular seat 1 and the annular cover 2 are matched in a rolling mode through the rolling bodies, the annular seat 1 and the annular cover 2 do not adopt other fixing modes, the design is favorable for processing and manufacturing of single parts, flow line production is favorable, and equipment manufacturing efficiency is improved.
Further, the rolling bodies comprise balls 4 and round pipes 5, and the balls 4 and the round pipes 5 are alternately arranged in the annular placing groove 101. Ball 4 be the steel ball, pipe 5 is straight pipe structure, straight pipe structure can reduce the processing degree of difficulty on the one hand, on the other hand tubular structure can reduce with the material, can also reduce weight.
Further, 3-5 circular tubes 5 are a group of circular tube groups, a plurality of circular tube groups are annularly arranged in the annular placing groove 101, and a ball 4 is placed between two adjacent groups of circular tube groups. This technical scheme has adopted ball 4 and the design of the cooperation use of pipe 5, and does not adopt the aim at of ball 4 alone: ball 4 roll nature is too strong, if be equipped with the clearance between ball 4, probably ball 4 can all crowd in an area, and does not have under gapped condition between ball 4, and ball 4's roll can be restricted, plays not fine rolling effect, and secondly ball 4's the processing degree of difficulty will be greater than pipe 5, and ball 4 also is more than the pipe with the material, if set up ball 4 into hollow spheroid, that processing degree of difficulty can greatly increased. Therefore, the technical scheme not only ensures the stability of the rotation of the annular cover 2, but also is beneficial to saving the manufacturing cost.
