[0021] The present invention is described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 3 As shown, the utility model is a liquid crystal display module with adjustable viewing angle, including a frame 1, an adjusting device 2 arranged on the frame 1 and a display screen 3 movably arranged on the adjusting device 2, the adjusting device 2 includes a mounting seat 21, a universal joint 22 arranged on the mounting seat 21, a telescopic push rod 23 used in conjunction with the universal joint 22, a joint seat 24 arranged at the telescopic end of the telescopic push rod 23 and a joint groove 25 opened on the joint seat 24, the mounting seat 21 is connected to the display screen 3, one end of the telescopic push rod 23 is connected to the frame 1, and the other end of the telescopic push rod 23 is connected to the universal joint 22 through the joint seat 24, and the universal joint 22 is rotatably arranged in the joint groove 25, so that the display screen 3 can be rotated relative to the frame 1 to adjust its position.

[0023] During use, when the display screen 3 is adjusted left or right, the display screen 3 drives the two universal joints 22 to swing left or right via the mounting base 21. Since the universal joints 22 are arranged within the joint slots 25, the universal joints 22 can rotate in multiple directions and angles within the joint slots 25. Moreover, the joint slots 25 are provided in the joint base 24, which is provided at the free telescopic end of the telescopic push rod 23. The joint base 24 is not mounted on the display screen 3. As a result, the universal joints 22 can rotate slightly around the joint slots 25 while also driving the telescopic push rod 23 to adjust the distance between the display screen 3 and the frame 1. This helps the display screen 3 rotate relative to the frame 1 to adjust the viewing angle, meet the user's different viewing angle change requirements, and enhance the user experience. The utility model adjusts the position of the display screen 3 according to different viewing angle adjustment requirements, is simple and convenient to operate, has a wide adjustment range, and has high angle adjustment accuracy.

[0024] The frame 1 of this embodiment is provided with a base 4, a slider 11 being provided at the bottom of the frame 1. The base 4 is provided with a guide rail 41 slidably connected to the slider 11, and a manual locking knob 12 is provided on the outer side of the slider 11. Specifically, the frame 1 slides along the length of the guide rail 41 via the slider 11, thereby driving the display screen 3 in the front-to-back direction through the frame 1. The manual locking knob 12 is then rotated and tightened to effectively fix the position of the slider 11 on the guide rail 41, providing simple operation and excellent positioning effect.

[0025] In this embodiment, a movable ball head 13 is provided in the middle of the frame 1, and a ball head slot 26 is provided in the middle of the mounting base 21. The movable ball head 13 is rotatably accommodated in the ball head slot 26. Specifically, the display screen 3 is mounted on the movable ball head 13 via the mounting base 21. Since the movable ball head 13 is rotatably accommodated in the ball head slot 26, and the ball head slot 26 is provided in the middle of the mounting base 21, the display screen 3 can be finely adjusted by swinging up and down relative to the frame 1. As the mounting base 21 swings up and down around the movable ball head 13 via the ball head slot 26, the universal joints 22 provided on both sides of the mounting base 21 also finely rotate around the joint slots 25, resulting in smooth rotation and effective positioning.

[0026] In this embodiment, the frame 1 is provided with an articulated seat 14 on its outer side. A hinge shaft 15 is provided at the connection between the articulated seat 14 and the telescopic push rod 23. Specifically, the telescopic push rod 23 is movably articulated to the articulated seat 14 via the hinge shaft 15. This facilitates the movement of the telescopic push rod 23 relative to the frame 1 when the display screen 3, via the mounting seat 21, drives the two universal joints 22 to swing left or right, thereby also driving the telescopic push rod 23 to swing left or right relative to the frame 1. This prevents structural damage caused by excessive restraint between the components.

[0027] The mounting base 21 of this embodiment is provided with a plurality of mounting holes 27, and the plurality of mounting holes 27 are provided, and the plurality of mounting holes 27 are arranged around the circumference of the mounting base 21. Specifically, the plurality of mounting holes 27 are arranged around the circumference of the mounting base 21, which facilitates the use of multiple external screws to insert corresponding mounting holes 27, thereby ensuring a stable connection between the mounting base 21 and the display screen 3.

[0028] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
