[0034] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0035] Embodiment 1

[0036] The present application provides a liquid crystal advertising machine with an adjustable base angle, aiming to solve the problems of inconvenient angle adjustment and difficulty in switching between horizontal and vertical screens of existing liquid crystal advertising machines. The present application will be described in detail below in conjunction with the accompanying drawings and embodiments:

[0037] See attached Figure 1-5 The LCD advertising machine body 1 is placed on the support base 2. The support base 2 not only plays a supporting role, but also has a built-in battery block to provide power for the entire device. A charging connector is provided on the side wall of the support base 2 to facilitate users to charge the battery block. An electric rotating base 3 is installed at the top center of the support base 2, which can realize the rotation of the LCD advertising machine body 1 on the horizontal plane;

[0038] A support shell 4 is fixed at the top center of the electric rotating seat 3. A first electric push rod 5 is installed inside the support shell 4. The output end of the first electric push rod 5 passes through the top opening of the support shell 4 and is fixedly connected to a support block 6. The support block 6 is designed to support the LCD advertising machine body 1 and allow it to be adjusted in height.

[0039] A movable plate 7 is provided at the center of the back of the LCD advertising machine body 1, and a mounting plate 8 is provided outside the movable plate 7. Two connecting rods 9 are symmetrically installed on the outer wall of the mounting plate 8. The other ends of the two connecting rods 9 are hinged to the support block 6, so that the LCD advertising machine body 1 can swing around the support block 6;

[0040] The inclination adjustment component is one of the core parts of the present application, which mainly includes an L-shaped mounting frame 12, which is fixed to one side of the support block 6. A second electric push rod 13 is installed on the L-shaped mounting frame 12, and its output end is hinged to the outer wall of the mounting plate 8 through a movable rod 14. When the second electric push rod 13 is extended and retracted, the mounting plate 8 and the movable plate 7 are driven to tilt together through the movable rod 14, thereby changing the inclination angle of the LCD advertising machine body 1, which can be adjusted to be completely flat at most;

[0041] The horizontal and vertical screen switching component is used to realize the switching of the LCD advertising machine body 1 between the horizontal and vertical screens. It mainly includes a driving motor 10 installed in the center of the outer wall of the mounting plate 8. The output shaft of the driving motor 10 passes through the inner wall of the mounting plate 8 and is fixedly connected to the rotating rod 11. The other end of the rotating rod 11 is fixedly connected to the center of the inner wall of the movable plate 7. When the driving motor 10 is working, it will drive the rotating rod 11 and the movable plate 7 to rotate together, thereby realizing the horizontal and vertical screen switching of the LCD advertising machine body 1;

[0042] In order to improve the stability of the movable disk 7 during the rotation process, the movable disk 7 is slidably installed in the groove of the inner wall of the mounting disk 8 through the convex ring on the outer wall. This design can effectively prevent the movable disk 7 from shaking or deflecting during the rotation process.

[0043] In summary, the present application realizes functions such as angle adjustment, horizontal and vertical screen switching, and height adjustment of the LCD advertising machine base through ingenious structural design, which greatly improves the flexibility and convenience of using the LCD advertising machine.

[0044] Embodiment 2

[0045] Improvements based on Example 1:

[0046] Please refer to Figure 1 In order to facilitate the movement of the entire device, universal wheels 15 are installed at the four corners of the bottom of the support base 2, and the user can easily move the device to a designated position as needed.

[0047] Please refer to Figure 3In order to prevent the LCD advertising machine body 1 from colliding with the support block 6 after being completely flattened, a buffer pad 16 is provided on the top of the support block 6. The buffer pad 16 can effectively protect the surface of the LCD advertising machine body 1 from damage.

[0048] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric rotating seat 3, the first electric push rod 5, the drive motor 10 and the second electric push rod 13 are commonplace, and are conventional means or common knowledge, and will not be elaborated here.
