Visitors need to move around the device to fully understand the equipment, which is extremely inconvenient, especially in crowded exhibitions. Second, the display state is rigid. The structure of the device is not adjustable, and it is impossible to switch the unfolded or retracted state of the device according to the display needs. When not in use, it occupies a lot of space and is inconvenient to transport and store. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a display device for educational information technology hardware equipment, which overcomes the shortcomings of the existing technology and effectively solves the problems of fixed angle and non-adjustable structure of traditional display devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A display device for educational information technology hardware includes a rotating tube. An electric push rod is fixedly connected to the inner wall of the bottom of the rotating tube by screws. A cross-shaped lifting block is fixedly connected to the piston rod of the electric push rod.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 Example 1: A display device for educational information technology hardware includes a rotating tube 1. An electric push rod 2 is fixedly connected to the inner wall of the bottom of the rotating tube 1 by screws. A cross-shaped lifting block 3 is fixedly connected to the piston rod of the electric push rod 2. A bottom sleeve 4 is provided on the outer wall of the cross-shaped lifting block 3. The outer wall of the bottom sleeve 4 is hinged to a first connecting rod 5 on all four sides. One end of the first connecting rod 5 is hinged to a drive rod 6, and one end of the drive rod 6 is hinged to a second connecting rod 7. A top sleeve 8 is sleeved on the top of the outer wall of the rotating tube 1. The outer wall of the top sleeve 8 is hinged to a driven rod 9 on all four sides.

[0026] In this embodiment, the electric push rod 2 is a small electric push rod of model DT500. Its working method is to drive the lead screw to rotate through the motor, thereby driving the piston rod to extend and retract, realizing linear reciprocating motion. The cross lifting block 3 slides up and down along the slide groove 25 under the drive of the electric push rod 2. The bottom sleeve 4 moves synchronously with the cross lifting block 3, thereby pushing the first connecting rod 5 to rotate. The first connecting rod 5 drives the drive rod 6 and the second connecting rod 7 to work together, providing power for the unfolding and retraction of the arc mounting plate 10. The top sleeve 8 is fixed to the top of the rotating tube 1 by screws. Its hinged driven rod 9 cooperates with the second connecting rod 7 to ensure the stability of the arc mounting plate 10 during movement.

[0027] Four curved mounting plates 10 are evenly distributed around the circumference of the rotating tube 1. The initial included angle between adjacent curved mounting plates 10 is 90°. The radius of curvature of a single curved mounting plate 10 is 50-80cm, the width is 30-40cm, and the weight is controlled at 5-8kg to ensure overall balanced weight distribution. The other end of the first connecting rod 5 is hinged to the outer peripheral wall of the bottom sleeve 4. The middle part of the drive rod 6 is rotatably connected to the hinge seat preset on the outer wall of the rotating tube 1. The other end of the second connecting rod 7 slides with the top slide rail 11 through a roller slider. The other end of the driven rod 9 also slides with the bottom slide rail 12 through a roller slider. The roller slider is made of bearing steel to reduce the coefficient of sliding friction.

[0028] In the second embodiment, an arc-shaped mounting plate 10 is provided around the outer wall of the rotating tube 1, and an educational information display screen 13 is installed on the outer side of the arc-shaped mounting plate 10. A top slide rail 11 and a bottom slide rail 12 are respectively provided on the top and bottom of the inner side of the arc-shaped mounting plate 10, and the second connecting rod 7 is in sliding cooperation with the top slide rail 11, and the driven rod 9 is in sliding cooperation with the bottom slide rail 12.

[0029] In this embodiment, the educational information display screen 13 and the curved mounting plate 10 are fixedly connected by screws. The educational information display screen 13 is a 22-inch touch teaching display screen of model T220. It works by connecting to an external power supply and control terminal to realize functions such as displaying teaching content and interactive touch. It is fixed to the outside of the curved mounting plate 10 by bolts. The curved design can improve the display viewing angle. When the second connecting rod 7 is pushed by the driving rod 6, it slides along the top slide rail 11, while the driven rod 9 slides along the bottom slide rail 12. The two work together to drive the curved mounting plate 10 to expand outward or retract inward, so as to adjust the display state of the educational information display screen 13 and adapt to different display scenario requirements.

[0030] The expansion / retraction limits are defined by elastic limit blocks at both ends of the top slide rail 11 and the bottom slide rail 12. The elastic limit blocks are made of polyurethane and serve as a buffer against impacts. A rotating conductive slip ring is installed on the top of the column 14. The power supply and signal lines of the educational information display screen 13 pass through the rotating conductive slip ring and are then connected to the external control terminal. The slip ring has a rated current of ≥5A and an insulation resistance of ≥100MΩ to ensure stable signal transmission and eliminate the risk of entanglement.

[0031] A column 14 is provided at the center of the bottom outer wall of the rotating tube 1, and a first bevel gear 15 is installed on the bottom outer wall of the column 14. A second bevel gear 16 meshes on the outer wall of the first bevel gear 15, and a reduction motor 17 is installed on one side of the outer wall of the second bevel gear 16.

[0032] According to the above scheme, the geared motor 17 is a 6IK140RGU-CF model geared motor 17. Its working principle is that the motor output shaft drives the second bevel gear 16 to rotate, using gear meshing to transmit power and reduce speed. After the geared motor 17 starts, the second bevel gear 16 drives the meshing first bevel gear 15 to rotate. The first bevel gear 15 drives the column 14 and the rotating tube 1 to rotate synchronously. The rotating tube 1 then drives the arc-shaped mounting plate 10 and the educational information display screen 13 to rotate, achieving a 360-degree all-around display. The speed can be adjusted by the motor controller to ensure smooth operation.

[0033] The geared motor 17 is equipped with an overload protection device, and its rotation speed adjustment range is 0.5-1 r / min. It automatically stops when the load exceeds 1.5 times the rated load. To improve the synchronization of multiple curved mounting plates 10, the synchronization error of each curved mounting plate 10 during unfolding / retraction is ≤2°, and the spacing difference is ≤3mm.

[0034] A base plate 19 is fitted at the bottom of the outer wall of the rotating tube 1, and a top plate 20 is fixedly connected to the top outer wall of the rotating tube 1. An arc-shaped mounting plate 10 is disposed between the base plate 19 and the top plate 20. A vertical tube 18 is installed on the bottom outer wall of the base plate 19, and a base 26 is installed on the bottom outer wall of the vertical tube 18. A column 14 is rotatably connected to the top outer wall of the base 26 through a bearing, and a reduction motor 17 is fixedly connected to the top outer wall of the base plate 19 through screws.

[0035] Through the above scheme, the base 26 is made of heavy-duty cast iron to enhance the overall device's anti-overturning ability. The vertical tube 18 is vertically welded to the top of the base 26, serving as the support structure for the chassis 19. The column 14 is connected to the base 26 via a deep groove ball bearing to reduce frictional resistance during rotation and ensure smooth rotation of the rotating tube 1. The chassis 19 and the top plate 20 are respectively fitted onto the bottom and top of the rotating tube 1, forming upper and lower limits for the arc-shaped mounting plate 10 to prevent it from shifting during movement or rotation.

[0036] The base 26 weighs ≥50kg, the overall device has an anti-tipping safety factor ≥1.8, and can support a maximum weight of 15kg for a single educational information display screen 13. Annular limiting grooves are provided on the chassis 19 and top plate 20 corresponding to the movement trajectory of the curved mounting plate 10. The upper and lower ends of the curved mounting plate 10 are embedded in the limiting grooves, and the gap between the limiting grooves and the curved mounting plate 10 is 0.5-1mm, further limiting the radial sway of the curved mounting plate 10.

[0037] A top rod 21 is provided at the center of the outer wall of the top plate 20, and a top protective plate 22 is provided on the outer wall of the top rod 21. A fixing ring 23 is welded on the outer wall of the riser 18, and an array of reinforcing rods 24 are provided between the fixing ring 23 and the base plate 19.

[0038] With the above-described scheme, the top rod 21 is vertically fixed to the center of the top plate 20. The top protective plate 22 is a circular plastic plate with a diameter larger than that of the top plate 20, which can shield dust or debris falling from the top and protect the curved mounting plate 10 and the educational information display screen 13. The fixing ring 23 is welded to the middle of the riser 18, and the reinforcing rods 24 are connected to the bottom of the chassis 19 in an array to form a triangular stable structure, which effectively distributes the weight of the chassis 19 and the upper components, prevents the riser 18 from deforming under stress, and enhances the stability of the device when rotating or unfolding.

[0039] The outer wall of the rotating tube 1 is provided with grooves 25 on all four sides, and the cross lifting block 3 is slidably connected to the inner wall of the groove 25.

[0040] With the above scheme, four grooves 25 are evenly opened along the outer circumference of the rotating tube 1. The cross-sectional shape of the grooves 25 is rectangular. The four protrusions of the cross lifting block 3 are rectangular blocks that are respectively embedded in the grooves 25, and the two are fitted with a clearance fit. When the electric push rod 2 drives the cross lifting block 3 to move up and down, the grooves 25 play a guiding and limiting role, preventing the cross lifting block 3 from rotating with the rotating tube 1 or from shifting, ensuring the precise movement of the bottom sleeve 4 and the connecting rod structure, thereby ensuring the synchronicity and stability of the arc mounting plate 10 when it unfolds and retracts, and avoiding component jamming.

[0041] Working principle: Before the display device is put into operation, the educational information display screen 13 is fixed on the outside of the curved mounting plate 10 and the power is turned on, and the display screen enters the standby state. When starting, if it is necessary to adjust the display angle, the geared motor 17 of model 6IK140RGU-CF can be turned on, which drives the second bevel gear 16 to rotate. The meshing first bevel gear 15 then drives the column 14 to rotate, which in turn drives the rotating tube 1, the base 19, the top plate 20 and the curved mounting plate 10 to rotate synchronously. The educational information display screen 13 can achieve 360-degree rotation display. The speed is adjusted to a stable state by the motor controller.

[0042] To switch the display status, activate the electric push rod 2 (model DT500). Its piston rod extends and retracts, causing the cross lifting block 3 to slide up and down along the slide groove 25. The cross lifting block 3 drives the bottom sleeve 4 to move. The first connecting rod 5, which is hinged to the bottom sleeve 4, pushes the drive rod 6. The drive rod 6 slides along the top slide rail 11 of the arc-shaped mounting plate 10 through the second connecting rod 7. At the same time, the driven rod 9, which is hinged to the top sleeve 8, slides along the bottom slide rail 12. The two work together to cause the arc-shaped mounting plate 10 to expand outward or retract inward, adapting to different display needs and equipment specifications.

[0043] During operation, the base 26 and the riser 18 provide bottom support, the fixing ring 23 and the reinforcing rod 24 enhance the stability of the chassis 19 and prevent shaking; the top protective plate 22 shields the equipment from debris.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
