Description

Technical Field

[0001] The utility model relates to the technical field of electronic drawing boards, in particular to a foldable dual-screen liquid crystal electronic drawing board. Background Art

[0002] Chinese patent document CN219120267U discloses a foldable dual-screen LCD electronic drawing board. The support frame is stored by providing a storage slot. When support is needed, the knob is turned to rotate the threaded rod, causing the slider to move in the slide slot, so that the connecting rod pushes the support frame out of the storage slot. The tilt angle of the drawing board body is adjusted by rotating the support frame. When the angle is appropriate, the knob is stopped, and the clamping ball is pushed into the clamping slot by the elastic body, so that the knob and the threaded rod are fixed, thereby preventing the support angle of the support frame from changing. The change of the support frame angle solves the problem that the user needs to lower his head for a long time to use the drawing board and cannot stand it up. At the same time, the drawing board body can be adjusted to a comfortable tilt angle for use. The display content of the main screen and the secondary screen is controlled by buttons. In the process of learning to copy and draw, the sample draft can be observed through the secondary screen, making the use of the drawing board body more convenient.

[0003] The above-mentioned foldable dual-screen LCD electronic drawing board adopts an integrated design when in use. Therefore, when one set of the LCD electronic drawing board is damaged, the entire dual-screen LCD electronic drawing board needs to be replaced, thereby increasing the maintenance cost of the LCD electronic drawing board, which is not conducive to promotion and use.
