Rotating connecting piece for tablet personal computer or mobile phone support

Abstract

The invention discloses a rotating connecting piece for a tablet personal computer or mobile phone support. The rotating connecting piece comprises a connecting base, a first connecting portion, a second connecting portion and a rotating assembly. The first connecting portion is arranged at one end of the connecting base. The rotating assembly comprises an upper positioning sleeve, a lower positioning sleeve, at least one bearing, an upper gear, a lower gear, a spring and a central spindle, wherein the upper positioning sleeve is connected with the other end of the connecting base; the second connecting portion is arranged at the lower end of the lower positioning sleeve; the upper gear and the lower gear are face gears and are meshed in a meshed interface; the spring pushes the upper and lower gears to be meshed; and the bearings, the upper gear, the lower gear and the spring penetrate the central spindle, and are fixed to the central spindle through fasteners and arranged on the upper positioning sleeve and the lower positioning sleeve in a sleeving manner. The connecting piece can be operated with one hand, is smooth in rotation and will not shake during rotation, the fasteners inside the connecting piece are not prone to looseness or disengagement, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of a tablet computer support, in particular to a rotary connection piece of a tablet computer or mobile phone support. Background technique [0002] The tablet computer support in the prior art is connected with a telescopic connection sleeve, and a connecting piece that controls and fixes the rotation angle between the arm and the arm of the rocking arm through a spring and two meshing teeth between the rocking arms. But these connectors all have the place of deficiency. For example, the telescopic connection sleeve can only be connected to a rod, and two hands must be coordinated during operation. For the connecting piece with the engaging piece, because the arm of the rocker arm has a certain weight applied to the engaging piece, and this weight makes the engaging piece bear the force deviated from the connection axis, on the one hand, the rocker arm is not stable when rotating. , may shake, on the othe...
