Trackball seat and trackball mounting and supporting structure

Abstract

The invention discloses a trackball seat and a trackball mounting and supporting structure. The trackball seat comprises an annular base, the annular base is provided with a first circular through hole, a lubricating supporting boss is arranged on the edge of the inner side, close to the upper end of the first circular through hole, of the annular base, the lubricating supporting boss is annular,is provided with a supporting circular through hole, and is provided with a horn-shaped supporting inclined face along the inner side of the upper end of the supporting circular through hole. According to the trackball seat, the horn-shaped supporting inclined face of the lubricating supporting boss is used for supporting the trackball to roll, so that the problem of high noise of the trackball isreduced and eliminated, the surface abrasion of the trackball is reduced and eliminated, and the service life of a trackball mouse is prolonged; and moreover, according to the trackball mounting supporting structure, the trackball seat is used for supporting the trackball to roll, and the upper cover is used for fixing the position of the trackball, so that the trackball can roll at any installation angle, and good control performance is provided for the trackball.

Description

technical field [0001] The invention relates to the field of industrial track balls, in particular to a track ball seat and a track ball installation support structure. Background technique [0002] Traditional desktop or notebook computers use a mouse or trackball device to control the cursor shift on the computer screen. Traditional industrial trackballs use bearings or zirconia beads as the support of the trackball, which causes the rolling sound of the ball. It is relatively large, and the general industrial trackball is made of 304 stainless steel. After a long time of use, there will be many scratches on the surface of the stainless steel ball, which will affect the use effect and appearance. [0003] Prior art, application number is CN200620149726.2 utility model patent, which discloses an optical trackball device, the optical trackball device includes a base, a top cover, a trackball, a light guide plate and an optical sensor There are multiple balls on the bearing ...
