[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0016] like Figures 1-2As shown, a multi-angle display device for economic data charts includes a base 1, a tablet computer 2, a rotating table 3, a display screen 4 and a back support 5. The base 1 has a built-in control box, and the upper end of the base 1 is provided with a lifting component 6. The output end of the lifting component 6 is connected to the lower end of the rotating table 3 to drive the rotating table 3 to rise and fall. The tablet computer 2 is a touch screen, and the tablet computer 2 can be detachably mounted on the rotating table 3. The lower end of the display screen 4 is hinged to the rotating table 3. The back support 5 is retractable, and the upper end of the back support 5 is hinged to the rear end of the display screen 4, and the lower end of the back support 5 is connected to the rotating table 3. The tablet computer 2, the rotating table 3 and the display screen 4 are all electrically connected to the control box. Specifically, in this embodiment, the base 1 has a built-in control box, and the control box integrates a control panel and a battery pack, which reduces the center of gravity of the entire device and has good stability. The lifting component 6 is set on the base 1, and the lifting component 6 is used to adjust the height of the rotating table 3, and then adjust the height of the display screen 4, which is convenient for teaching adaptation. In order to facilitate students in different directions to watch the economic data charts displayed on the display screen 4, a rotating table 3 is used to support the tablet computer 2 and the display screen 4, wherein the tablet computer 2 is detachable and electrically connected to the control box in the base 1 through a spring line. The tablet computer 2 can be used as the back end of the explanation teacher, without bending over to operate on the touch-screen display screen 4. The specific operation is as follows: when it is necessary to modify the chart data displayed on the display screen 4, the explanation teacher can directly operate on the tablet computer 2, and then synchronize the data to the display screen 4 through the control box for display, which has strong synchronization and avoids the explanation teacher standing in front of the display screen 4 to touch the blackboard, which will not only block the students' sight, but also damage the waist muscles of the explanation teacher over time. The rotating table 3 can rotate the direction of the display screen 4, and in order to adjust the inclination angle of the display screen 4 and prevent the display screen 4 from shaking during the rotation process and improve stability, we use a back support 5 to support the display screen 4, which is retractable. With the hinged structure of the display screen 4 and the end face of the rotating table 3, the display screen 4 can be rotated around the hinged structure with the rotating table 3, which is more convenient for display.

[0017] like Figures 1-2 As shown, a pulley 11 is also provided at the bottom of the base 1, and the entire device is movable, which is convenient for range display in the classroom and is more convenient and labor-saving to carry.

[0018] like Figures 1-2As shown, the lifting assembly 6 includes a back frame 61, a motor 62, a screw rod 63, a sleeve 64, a sleeve 65 and a protective shell 66. The two ends of the screw rod 63 are movably connected to the two ends of the back frame 61 through bearings. The output end of the motor 62 is connected to the screw rod 63 to drive the screw rod 63 to rotate. The sleeve 64 is movably sleeved on the screw rod 63. The sleeve 64 abuts against the side of the back frame 61. The lower end of the sleeve 65 is connected to the sleeve 64, and the upper end of the sleeve 65 is connected to the rotating table 3. The protective shell 66 is sleeved outside the back frame 61. Specifically, when in use, the back frame 61 is used as a guide plate and is movably connected with the sliding sleeve 64. When the motor 62 drives the screw rod 63 to rotate, the sliding sleeve 64 is built with a nut head that matches the thread of the screw rod 63. When the nut head moves up and down along the screw rod 63, it can drive the sliding sleeve 64 to move up and down synchronously. During the displacement of the sliding sleeve 64, the sleeve 65 can be driven to move synchronously. The sleeve 65 serves as a support for the rotating table 3 to achieve the purpose of adjusting the height of the rotating table 3. The back frame 61 is covered with a protective shell 66. The protective shell 66 is made of a plastic shell, which is low in cost and protects the motor 62 and the screw rod 63 to prevent leakage and unsightly appearance.

[0019] like Figure 2 As shown, the output end of the motor 62 is connected to the screw rod 63 through a coupling 621. The coupling 631 is used to transmit torque and play a shock-absorbing and buffering role to prevent misalignment due to installation accuracy errors and compensate for radial displacement.

[0020] like Figures 1-2 As shown, a snap-in slot 31 is provided on the table surface of the rotating table 3, and a socket 21 is installed at the bottom of the tablet computer 2 corresponding to the snap-in slot 31. Specifically, in this embodiment, the snap-in slot 31 is used to cooperate with the socket 21 to fix the tablet computer 2, so as to prevent the tablet computer 2 from falling off the table surface of the rotating table 3 and being damaged when not in use.

[0021] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
