Problems solved by technology

[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 structure of the trackball. When the trackball is vertical or When the installation is tilted at a large angle, the trackball control will fail or the effective control effect will not be achieved.
[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 The measuring element; wherein a plurality of balls are arranged in the bearing groove of the base, and the optical trackball device uses the balls to support the rolling of the trackball. Ineffective or unable to achieve effective control effect

Abstract

The invention discloses an industrial trackball mouse. The industrial trackball mouse comprises a shell, a lubricating support ball seat, a trackball, a dustproof ring and an optical sensing assembly,the shell internally comprises a ball accommodating cavity, a circuit accommodating cavity and a light hole, and the ball accommodating cavity communicates with the circuit accommodating cavity through the light hole; the lubricating support ball seat is provided with a first round hole, the bottom end of the trackball is installed at the bottom of the ball accommodating cavity through the lubricating support ball seat, and the bottom end edge of the trackball protrudes downwards out of the first round hole of the lubricating support ball seat; the dustproof ring is provided with a second round hole, the top end of the trackball is installed at the top of the ball accommodating cavity through the dustproof ring, and the top end edge of the trackball protrudes upwards out of the second round hole of the dustproof ring; and the optical sensing assembly is installed in the circuit accommodating cavity. According to the industrial trackball mouse, the trackball is supported by a trackballseat to roll, and the position of the trackball is fixed by the dustproof ring, so that the trackball can roll at any mounting angle, and good control performance is provided for the trackball.
