The near-sighted computer base of anti-hunchback of a kind of and arm-chair interlock is characterized in that described base can link with operator's sitting posture, in case abnormal sitting posture is true, and computer screen deflection and can not using.

One direct current reducing motor is installed on the base; Bearing is installed on the base by screw, and driving gear is installed on the output shaft of DC speed-reducing, is meshed with driven internal gear; Driven internal gear is connected with pallet by screw, and screw and pallet are supported on the bearing by thrust rolling bearing; Settle two position limit switches in the epicoele of bearing, two switches are 90 degree to the angle between the bearing center line line, and the plectrum that is provided with on the pallet is between the two; Power is exported from motor, through gear transmission, is delivered to pallet, realizes rotatablely moving of pallet.

Above-mentioned motor is controlled by the sitting posture of human body, and when people's back leans against on the leather mat of arm-chair (correct body position), the control mechanism that is positioned at arm-chair makes the display screen base in the normal position; When the operator has broken away from the normal position, the control mechanism of arm-chair makes the base of display screen 90 degree that deflect, and sends a telegraph brain and can not use; Computer will recover the normal position when sitting posture is replied just often.

The realization of appeal interlock function can directly connect by electric wire, also can pass through remote control unit.

The present invention has following outstanding advantage and remarkable result than prior art:

1, the computer popularity rate is very high, and any unscientific use will cause sizable crowd to suffer the injury of health, the present invention is based on the control that prevents deformity of spine eyesight myopia and disease of cervical vetebra and has released the effectively preventing measure.

2, the present invention is ad hoc platform is applicable to all computers, then benefits vast computer user, so have popularization;

3, the present invention has released a theory, is to solve completely by technological means is in addition disposable for some a little intractable bad habit promptly.
