Description

Technical Field

[0001] The utility model relates to the technical field of display boards, in particular to a data display board. Background Art

[0002] As we all know, the literal meaning of project cost is the construction price of the project. There are three elements of project pricing: quantity, price and fee. In a broad sense, project cost covers construction project cost, highway project cost, water transport project cost, railway project cost, water conservancy project cost, power project cost, communication project cost, aerospace project cost, etc. The staff needs to calculate according to the data displayed on the drawings. In order to facilitate the staff to view the drawings, the drawings need to be placed on the data display board.

[0003] In real life, most data display boards can generally adjust the tilt angle of the display board, so that the tilt angle can be adjusted according to people of different heights to achieve the best viewing effect. When adjusting the tilt angle of the display board, it is necessary to loosen the fastening bolts on both sides of the connecting rod at the rear of the display board, and then rotate the connecting rod to drive the display board to rotate, and finally tighten the fastening bolts to fix the display board. This adjustment method is cumbersome, inconvenient to operate, and takes a lot of time. It is impossible to adjust the tilt angle of the display board conveniently and quickly, so it is not very practical and there is room for improvement. Utility Model Content
