Abstract

An adjustment apparatus capable of remembering screen viewing angle mainly includes an adjustment device on a device body that equips with a screen. The adjustment device includes a body for housing a screw bar and an adjustment wheel. The adjustment wheel may be adjusted and turned by hands to drive the screw bar to extend forwards or retract rearwards so that the bucking position of the head end of the screw bar against the action zone of the lid may be changed thereby to control the swinging angle of the lid, and adjust and remember the viewing angle.

Claims

1. An adjustment apparatus having memory of a screen viewing angle, comprising:

a device body having an adjustment device located thereon, and

a lid pivotally coupled on one side of the device body having a screen located thereon;

wherein the adjustment device includes a body which houses a screw bar and an adjustment wheel for driving the screw bar to extend forwards or retract rearwards such that bucking position of a head end of the screw bar against an action zone of the lid changes thereby to control a swinging angle of the lid to adjust and remember the viewing angle upon opening and closing lid.

2. The adjustment apparatus of claim 1, wherein the device body has a first bracing dock and a second bracing dock located on one end thereof corresponding to each other for pivotally engaging with a first pivot seat and a second pivot seat located on the lid to form a turning axis of the lid.

3. The adjustment apparatus of claim 2, wherein the first bracing dock is coupled with a spring reed.

4. The adjustment apparatus of claim 2, wherein the second bracing dock is coupled with a gear set which has a pinion to engage with a spindle gear located on the periphery of the second pivot seat.

5. The adjustment apparatus of claim 1, wherein the device body further includes a control button which has a biased rib on one side to push a latch tongue to latch in a coupling trough formed on a front side of the lid for anchoring the lid in a closed condition.

6. The adjustment apparatus of claim 1, wherein the device body has an adjustment window corresponding to the adjustment device.

7. The adjustment apparatus of claim 1, wherein the screw bar has an external thread section and a head end on one end thereof for bucking the action zone of the lid, the adjustment wheel having an internal screw thread to couple with the screw bar.

8. The adjustment apparatus of claim 1 further having a plurality of video and audio jacks to output or input signals.

9. The adjustment apparatus of claim 1 further including a video audio player for displaying pictures on the screen.
