The utility model provides a technical solution: a liquid crystal display with an adjustment function, including a base 1 and a liquid crystal screen 2, a sleeve 3 is provided above the base 1, a slide rod 4 is slidably provided in the sleeve 3, a limit plate 5 is rotatably installed on the upper end of the slide rod 4, an adjustment seat 6 is fixedly provided above the limit plate 5, an adjustment component connected to the liquid crystal screen 2 is provided in the adjustment seat 6, a fixed plate 7 is fixedly installed on the slide rod 4, a positioning plate 8 slidably connected to the slide rod 4 is provided above the fixed plate 7, a spring 9 is installed between the positioning plate 8 and the fixed plate 7, a plurality of positioning protrusions 10 are provided on the upper wall of the positioning plate 8 in a ring array, a positioning groove 11 matching the positioning protrusion 10 is provided on the lower wall of the limit plate 5, and a lifting component is provided on one side of the sleeve 3.

By adopting the above technical solution, when the LCD screen needs to be rotated, the positioning plate is slid downward to separate the positioning protrusion from the positioning groove, and the spring is compressed. At this time, the limit plate loses the limiting effect of the positioning protrusion, and can drive the adjustment seat to rotate, so that the LCD screen rotates synchronously. After rotating to an appropriate angle, the spring drives the positioning plate to rise and reset, so that the positioning protrusion is reinserted into the positioning groove of the limit plate, thereby locking the limit plate and improving the stability of the LCD screen.

This embodiment is further configured as follows: the adjustment component includes a rotating shaft 12 rotatably installed in the adjustment seat 6, a worm gear 13 is provided on the rotating shaft 12, a worm 14 meshing with the worm gear 13 is rotatably installed in the adjustment seat 6, the upper end of the worm 14 passes through the upper wall of the adjustment seat 6 and is provided with a handle, a pair of connecting rods 15 are fixedly provided on the rotating shaft 12, and a pair of arc grooves 16 for the connecting rods 15 to pass through are opened on the side walls of the adjustment seat 6, and the connecting rods 15 pass through the arc grooves 16 and are fixedly connected to the LCD screen 2.

By adopting the above technical solution, when the pitch angle of the LCD screen needs to be adjusted, the worm is rotated to drive the worm wheel and the rotating shaft engaged therewith to rotate synchronously, and a pair of connecting rods on the rotating shaft then drive the LCD screen to flip up and down, thereby achieving the adjustment of the pitch angle.

This embodiment is further configured such that the lifting assembly includes a pair of supports 17 arranged on the side wall of the sleeve 3, a screw 18 is rotatably installed between the pair of supports 17, a slide groove 19 is provided on the side wall of the sleeve 3, a slider 20 screwed to the screw 18 is provided in the slide groove 19, and one end of the slider 20 is fixedly connected to the slide rod 4.

By adopting the above technical solution, the screw rod is rotated so that the slider screwed thereon drives the slide bar to move up and down along the slide groove, so that the height of the LCD screen can be adjusted to meet different needs.

The present embodiment is further configured such that guide grooves 21 are provided on both sides of the slide rod 4 , and guide blocks 22 matching the guide grooves 21 are provided on the inner wall of the positioning plate 8 .

By adopting the above technical solution, the setting of the guide groove and the guide block can make the positioning plate slide up and down stably, avoiding the positioning plate from rotating.

This embodiment is further configured such that a handle is installed at one end of the screw rod 18 .

By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

Embodiment: When in use, the orientation angle, pitch angle and height of the LCD screen 2 can be adjusted according to the use requirements. When the LCD screen 2 needs to be rotated, the positioning plate 8 is slid downward to separate the positioning protrusion 10 from the positioning groove 11, and the spring 9 is compressed. At this time, the limit plate 5 loses the limiting effect of the positioning protrusion 10, and the adjustment seat 6 can be driven to rotate, so that the LCD screen 2 rotates synchronously. After rotating to a suitable angle, the spring 9 drives the positioning plate 8 to rise and reset, so that the positioning protrusion 10 is reinserted into the positioning groove 11 of the limit plate 5, thereby locking the limit plate 5 and improving the stability of the LCD screen 2;

When the pitch angle of the LCD screen 2 needs to be adjusted, the worm 14 is rotated to drive the worm wheel 13 and the rotating shaft 12 meshing therewith to rotate synchronously, and a pair of connecting rods 15 on the rotating shaft 12 then drives the LCD screen 2 to flip up and down, thereby achieving the adjustment of the pitch angle;

The screw rod 18 is rotated to make the slider 20 screwed thereon drive the slider 4 to move up and down along the slide groove 19, so that the height of the LCD screen 2 can be adjusted to meet different needs.
