The adjustment component includes a base, a fixed plate, a worm gear, a first bevel gear, a second bevel gear, a transmission shaft, a turntable, a knob, a screw, a worm wheel, a first trapezoidal lead screw, and a first lead screw nut. The fixed plate is fixed inside the base. A worm gear is installed in a bearing at the opening on the surface of the fixed plate. A first bevel gear is installed at the right end of the worm gear. A second bevel gear is connected to the outside of the first bevel gear. A transmission shaft passes through the middle of the second bevel gear. A turntable is sleeved on the outside of the transmission shaft. A screw is screwed into a screw hole on the surface of the turntable. A knob is fixed at the front end of the screw. A worm wheel is connected to the outside of the worm gear. A first trapezoidal lead screw passes through the middle of the worm wheel. A first lead screw nut is connected to the outside of the first trapezoidal lead screw. The movable base is located outside the first lead screw nut.

[0007] Furthermore, the drive shaft is disposed in the bearing at the opening on the right side of the base surface, and the worm and the drive shaft are perpendicular to each other.

[0008] Furthermore, the worm gear and the trapezoidal lead screw are perpendicular to each other, and the trapezoidal lead screw is rotatably connected to the base. Two worm wheels, two trapezoidal lead screws, and two lead screw nuts are provided.

[0009] Furthermore, mounting blocks are provided on both sides of the top of the movable seat, and a rotating shaft is provided on the mounting blocks.

[0010] Furthermore, a servo motor is installed at the center of the front end of the movable seat, and the output end of the servo motor is connected to a trapezoidal lead screw.

[0011] Furthermore, the trapezoidal lead screw 2 is externally connected to a lead screw nut 2, and a connecting piece 1 is provided on the top of the lead screw nut 2.

[0012] Furthermore, a connecting rod is hinged to the top of the first connecting member, and a second connecting member is hinged to the top of the connecting rod.

[0013] This utility model provides a multi-mode image adjustment device for a high-efficiency liquid crystal display screen, which has the following beneficial effects:

[0014] 1. This utility model rotates the turntable, transmission shaft, and bevel gear 2 by applying force to the knob. The bevel gear 2 meshes with bevel gear 1 to transmit power, causing the worm gear to rotate.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2 As shown, a multi-mode screen adjustment device for a high-efficiency liquid crystal display includes an adjustment component 1 and a movable base 2. The adjustment component 1 includes a base 101, a fixed plate 102, a worm gear 103, a first bevel gear 104, a second bevel gear 105, a drive shaft 106, a turntable 107, a knob 108, a screw 109, a worm wheel 110, a trapezoidal lead screw 111, and a lead screw nut 112. The fixed plate 102 is fixed inside the base 101. The worm gear 103 is installed in the bearing at the opening on the surface of the fixed plate 102. The right end of the worm gear 103 is provided with a first bevel gear 104. The second bevel gear 105 is connected to the outside of the first bevel gear 104. The drive shaft 106 passes through the middle of the second bevel gear 105. A turntable 107 is fitted externally, and a screw 109 is screwed into a screw hole on the surface of the turntable 107. A knob 108 is fixed to the front end of the screw 109. A worm gear 110 is connected to the outside of the worm gear 103, and a trapezoidal lead screw 111 passes through the middle of the worm gear 110. A lead screw nut 112 is connected to the outside of the trapezoidal lead screw 111. A movable seat 2 is located outside the lead screw nut 112. A transmission shaft 106 is located in a bearing at the opening on the right side of the surface of the base 101. The worm gear 103 and the transmission shaft 106 are perpendicular to each other, and the worm gear 103 and the trapezoidal lead screw 111 are perpendicular to each other. The trapezoidal lead screw 111 is rotatably connected to the base 101. There are two worm gears 110, two trapezoidal lead screws 111, and two lead screw nuts 112.

[0022] The specific operation is as follows: by applying force to the knob 108, the turntable 107, the drive shaft 106, and the second bevel gear 105 are rotated. The second bevel gear 105 meshes with the first bevel gear 104 to transmit power, causing the worm gear 103 to rotate. This, in turn, drives the worm wheel 110 to drive the trapezoidal lead screw 111 to rotate, so that the moving seat 2 follows the lead screw nut 112 to move up and down. This effectively adjusts the height of the LCD screen, making it suitable for users of different heights.

[0023] like Figure 3 As shown, mounting blocks 3 are provided on both sides of the top of the movable base 2, and a rotating shaft 4 is provided on the mounting block 3. A servo motor 5 is installed in the middle of the front end of the movable base 2, and a trapezoidal lead screw 6 is connected to the output end of the servo motor 5. A lead screw nut 7 is connected to the outside of the trapezoidal lead screw 6, and a connector 8 is provided on the top of the lead screw nut 7. A connecting rod 9 is hinged to the top of the connector 8, and a connecting piece 10 is hinged to the top of the connecting rod 9.

[0024] The specific operation is as follows: the servo motor 5 drives the trapezoidal lead screw 6 to rotate, and the lead screw nut 7 drives the connecting piece 8 to move along the outside of the trapezoidal lead screw 6, so that the angle of the connecting rod 9 changes slowly. This causes the LCD screen installed at the rear end of the connecting piece 10 to tilt, allowing the user to view the LCD screen in the most comfortable posture, thus improving the user experience.

[0025] In summary, this high-efficiency LCD screen multi-mode image adjustment device, when in use, first installs the LCD screen between the two rotating shafts 4 and fixes the connecting piece 2 10 to the back of the LCD screen. When it is necessary to adjust the display angle of the LCD screen, the servo motor 5 is started, causing the trapezoidal lead screw 2 6 to rotate under the drive of the servo motor 5. This, in turn, drives the lead screw nut 2 7 and the connecting piece 1 8 to move, causing the connecting rod 9, which is hinged to the connecting piece 1 8, to slowly rotate, causing the LCD screen to tilt. This allows for high-efficiency adjustment of the display angle of the LCD screen in multiple modes, including eye level, upward tilt, and downward tilt, to meet the different usage needs of different users.

[0026] Furthermore, by holding the knob 108, rotational force is provided to the turntable 107, drive shaft 106, and bevel gear 105, which drives bevel gear 104 and worm gear 103 to rotate. The worm gear 103 and worm wheel 110 drive the trapezoidal lead screw 111 to rotate, causing the moving seat 2 to move up and down with the lead screw nut 112, thereby realizing the height adjustment of the LCD screen. This makes it easy to adjust the LCD screen to face the user's eyes, allowing the user to view the LCD screen in the most comfortable posture, thus improving the user experience. By screwing the screw 109 into the screw hole on the surface of the base 101, the turntable 107 can be locked, making the height of the LCD screen more stable.
