Embodiment 1
[0017] The indexable display screen of this embodiment is applied in figure 1 As shown in a tax terminal, the host computer of the tax terminal is installed in an upper shell 1 and a lower shell (not shown in the figure) that are combined, and the upper shell is used as an installation shell for placing a display screen 2 .
[0018] Such as figure 2 and image 3 As shown, the outer surface of the upper case 1 extends toward the direction of the display screen 2 with left and right rotating support columns 1-1, and the inner surface is fixedly installed with left and right brackets 1-3. The specific installation structure is that the inner surface of the upper shell 1 is provided with a positioning boss 1-2 at the installation position. Corresponding positioning concave, during installation, the positioning boss is inserted in the corresponding positioning concave and fixed with fasteners, and the fan-shaped faces of the left and right brackets 1-3 extend toward the directio...

The invention relates to a turning display screen, and belongs to the technical field of terminal display devices. The turning display screen comprises a mounting housing and a display screen which is arranged on the mounting housing; the mounting housing extends towards the direction of the display screen to form a left rotary support pillar and a right rotary support pillar and extends towards the direction away from the display screen to form a left bracket and a right bracket, the extension ends of the left rotary support pillar and the right rotary support pillar are respectively provided with opposite shaft recesses, the left bracket and the right bracket are respectively provided with an arc groove which takes the center of the shaft recess as the center of circle; the lower part of the display screen is provided with a rotating shaft and extends backward to form a left elastic arm and a right elastic arm which tend to extend outwards; and the two ends of the rotating shaft arerespectively matched with the rotating shaft recesses of the left rotary support pillar and the right rotary support pillar, and the two ends form a revolving pair after being assembled, and the extension ends of the left elastic arm and the right elastic arm are respectively provided with a projection which is matched and assembled with the arc grooves of the left bracket and the right bracket, and the extension ends form a moving pair after being assembled. The turning display screen can realize stepless adjustment of the angle of the display screen, has simple structure, convenient assembly, and good hand feel in adjustment, and is stable and reliable.
Description
technical field [0001] The invention relates to an indexable display screen, in particular to an improved structure of a display screen indexing support device, which belongs to the technical field of terminal display devices. Background technique [0002] According to the applicant's knowledge, the angle of the LCD liquid crystal display screen of terminal equipment such as tax-controlled cash registers cannot be adjusted basically. And only one angle will cause the user's operating posture to be single, making people prone to fatigue. After improvement, the angle of some main display screens can be adjusted. Its structure is that the lower cover of the main display screen is knurled with straight lines within a certain angle range, and a friction plate is installed on the corresponding matching position on the main display screen seat. When adjusting the angle, the required angle is selected by the frictional engagement between the friction plate and the straight grain kn...
