Description

Display device with adjustable screen height

The present invention relates to a display device having an image display and a stand according to a video signal input from the outside, and more particularly, to a display device improved to be able to adjust the height of the main body from the stand freely.

In general, a display device including a main body on which an image is displayed and a stand supporting the main body may have a tilting function of allowing the main body 1 to be adjusted up and down from the stand 2 as shown in FIGS. 1 and 2. It is also possible to perform a swivel action to adjust the screen angle of the main body 1 from the stand 2 in the left and right directions.

However, since the display device of the prior art cannot adjust the height of the main body 1 from the stand part 2, the user cannot properly adjust the height of the screen of the main body 1 so that it is suitable for time. have.

Therefore, even if the screen of the main body 1 is used to properly adjust the angle in the up, down, left, right direction, it does not exactly match the viewing angle of the user is causing some inconvenience.

In particular, since the conventional display device is only to adjust the tilt and swivel angle, there is a problem that the image quality is deteriorated by the illumination when only adjusting the angle.

The present invention has been made in view of the above-mentioned problems in the related art, and a display device having a main body and a stand is provided to provide a display device that a user can adjust and use the screen height of the main body.

Another object of the present invention is to provide a display device in which the screen height of the main body is automatically adjusted by a simple switch operation.

In order to achieve the above object, the present invention provides a forward and reverse motor that is rotated forward and reverse by an on / off operation of a switch installed in a stand, and the dignity of being rotated by the forward and reverse motor power, The dignity wheel rotated in engagement with the dignity, the screw shaft is rotated forward and backward by the dignity wheel, the nut tool to be moved up and down by the screw shaft, the nut is mounted and the standtop is tilt and swivel angle adjustment at the top It is characterized in that the main body is configured to be raised and lowered so as to be configured as a stand-top support that is installed to enable.

Hereinafter, the display device according to the present invention will be described in detail with reference to the accompanying drawings.

3 to 5 show a display device according to the present invention, the display device includes a main body 10 displaying an image by a video signal input from the outside and a stand portion 20 supporting the main body 10. It consists of.

Therefore, the stand part 20 is provided so that the switch 30 for adjusting the height of the main body 10 can be operated from the outside.

In addition, the inside of the stand portion 20 is installed so that the forward and reverse motor 31, which is rotated forward and reverse by the on / off pressing operation of the switch 30, is fixed.

In the operation of the switch 30 for driving the forward and reverse motors 31, when the upper portion of the switch 30 is pressed, the forward and reverse motors 31 are rotated forward and backward, and the switch ( When the control unit 30 is positioned, the forward and reverse motors 31 are stopped, and when the lower part is pressed, the three-stage switch for driving the forward and reverse motors 31 in reverse rotation is used and operated.

The dignity 32 is connected to the motor shaft 31a of the forward and reverse motors 31 so that the forward and reverse rotations are performed, and the dignity 32 is a bushing support part 21 (21 ') of the stand part 20. It is configured to engage with the dignity wheel (33) of the screw shaft (34), which is installed so as to stand upright by).

The screw portion 34a formed on the upper portion of the screw shaft 34 has a nut hole 35 fixed to the lower end of the stand top pedestal 22, and the stand top pedestal 22 is a stand portion 20. It is configured to move up and down in the moving space (23).

Accordingly, the stand top pedestal 22 has straight grooves 22a protruding from both sides thereof, and the anti-rotation protrusion 23a formed at the upper end of the moving space 23 of the stand 20 is provided at the straight groove 22a. It is intended to be inserted.

Therefore, the stand top pedestal 22 is moved only in the straight direction in the up and down direction in the stand portion 20, so as not to rotate in the left and right directions.

In addition, the upper part of the stand top pedestal 22, the stand top 24 is fixed to the main body 10 is installed to adjust the screen angle in the up, down, left, and right directions, such tilt and swivel operation and structure Since already known technology, detailed drawings and descriptions thereof will be omitted.

Therefore, the present invention is the forward and reverse motor 31 is driven forward or reverse rotation by the operation of the switch 30, the dignity 32 and the dignity wheel 33 is forward and reverse rotation of power transmission, and also The screw shaft 34 having the dignity wheel 33 is rotated forward and backward.

In addition, when the screw shaft 34 rotates forward, the nut sphere 35 moves upwardly, and when the reverse rotation rotates, the stand top pedestal 22 moves up and down.

In addition, even if the stand top and bottom of the stand 22 is completed, even if the switch 30 continues to be pressed, the forward and reverse motor 31 is a small motor, so even if some load is no longer lifted or lowered When the operation of the switch 30 is stopped, a large abnormality does not occur.

Therefore, the user moves the stand top pedestal 22 up and down by an appropriate switch 30 operation, and the height of the main body 10 is properly adjusted by the lifting and lowering operation of the stand top pedestal 22. will be.

And while adjusting the height of the main body 10 as described above, it is possible to move the stand top 24 in the left, right and up and down directions, so that the screen angle can be adjusted.

According to the above description, since the screen of the main body can be adjusted appropriately according to the present invention, the screen height can be positioned parallel to the user's field of vision, thereby reducing eye fatigue and minimizing interference of the screen by lighting. At the same time, there is an effect of maintaining a good quality of the original display device.
