[0022] The present utility model proposes a rotating shaft structure applied to a flip - cover product.
[0023] Such as Figures 1 to 4As shown in the figure, in an embodiment of the present utility model, the rotating shaft structure applied to a flip product includes a rotating shaft 101, a rotating shaft bracket 102, a first gasket 103, a second gasket 104, a first disc spring 105, and a nut 106. A first connecting rod 1011 and a second connecting rod 1021 are respectively protruded at the front end and the rear end of the rotating shaft 101. The cross-sections of the first connecting rod 1011 and the second connecting rod 1021 are both arranged in an elliptical structure. A through hole 1021 is recessed at the lower end of the rotating shaft bracket 102. The first connecting rod 1011 is rotatably disposed through the through hole 1021. The first gasket 103 and the second gasket 104 are respectively disposed on both sides of the lower end of the rotating shaft bracket 102. The first gasket 103 and the second gasket 104 are respectively recessed with a through groove 109 adapted to the first connecting rod 1011. The first connecting rod 1011 is respectively disposed through the through groove 109. The first disc spring 105 is disposed outside the second gasket 104. The first connecting rod 1011 is disposed through the first disc spring 105. The two side walls of the first gasket 103 are respectively abutted against the side walls of the rotating shaft 101 and the rotating shaft bracket 102. The two side walls of the second gasket 104 are respectively abutted against the side walls of the rotating shaft bracket 102 and the first disc spring 105. An external thread 1013 is provided on the outside of the first connecting rod 1011. The nut 106 is screwed onto the external thread 1013, and the nut 106 is abutted against the first disc spring 105.
[0024] Further, a second disc spring 107 is further included. The second disc spring 107 is disposed outside the first disc spring 105. The two side walls of the second disc spring 107 are respectively abutted against the first disc spring 105 and the nut 106. The second disc spring further increases the magnitude of the elastic force, thereby increasing the damping magnitude of the rotating shaft and facilitating the connection of a heavier rotating member.
[0025] Further, a third gasket 108 is further included. The third gasket 108 is disposed outside the second disc spring 107. The third gasket 108 is recessed with a through groove 109 adapted to the first connecting rod. The first connecting rod 1011 is respectively disposed through the through groove 109. The two side walls of the third gasket 108 are respectively abutted against the second disc spring 107 and the nut 106. The third gasket 108 facilitates the nut to squeeze the second disc spring.
[0026] Further, a plurality of first mounting holes 1014 are recessed in the second connecting rod 1012, which facilitates the connection and fixation of the rotating shaft to an external rotating member.
[0027] Further, mounting plates 1022 are respectively protruded on both side walls of the upper end of the rotating shaft bracket 102. Second mounting holes 1023 are respectively recessed in the mounting plates 1022, which facilitates the installation and fixation of the rotating shaft bracket.
[0028] Further, the outer peripheral wall of the first connecting rod 1011 is slidably abutted against the inner peripheral wall of the through hole 1021, making the rotation process of the rotating shaft more stable and smooth.
[0029] Further, the nut 106 is a plastic nut. Compared with ordinary metal nuts, the plastic nut has good insulation performance and does not conduct electricity. It will not generate signal interference such as eddy currents under the influence of current or other electrical signals. Its anti-interference advantage is suitable for industries such as communication.
[0030] Specifically, the working principle and process of the present utility model are as follows: A first connecting rod and a second connecting rod are respectively protruded from the front end and the rear end of the rotating shaft. The cross-sections of the first connecting rod and the second connecting rod are both arranged in an elliptical structure. A through hole is recessed at the lower end of the rotating shaft bracket. The first connecting rod is rotatably disposed through the through hole. The first gasket and the second gasket are respectively disposed on both sides of the lower end of the rotating shaft bracket. The first gasket and the second gasket are respectively recessed with a through groove adapted to the first connecting rod. The first connecting rod is respectively disposed through the through groove. The first disc spring is disposed outside the second gasket. The first connecting rod is disposed through the first disc spring. The two side walls of the first gasket are respectively abutted against the side walls of the rotating shaft and the rotating shaft bracket. The two side walls of the second gasket are respectively abutted against the side walls of the rotating shaft bracket and the first disc spring. An external thread is provided on the outer side of the first connecting rod. The nut is screwed onto the external thread, and the nut is abutted against the first disc spring. Thus, the damping of the rotating shaft can be flexibly adjusted by loosening or tightening the nut as needed, avoiding too loose or too tight fit, making the rotation process of the rotating shaft smoother. The rotating shaft can rotate 360°, and the damping is constant during the rotation process of the rotating shaft, making the rotation process of the rotating shaft more stable and smooth, and the rotating shaft can be stably fixed at any angle, effectively improving the experience during the flipping process of the flip product.
