According to the shape of the display screen 1, a suitable frame plate 2 is selected, and the frame plate 2 is aligned with the rear side of the display screen 1. The rubber ring 4 is sleeved on the surface of the screw. At this time, multiple screws on the rear side of the display screen 1 correspond to penetrate the frame plate 2, and the nut 3 is spirally sleeved on the rear end of the screw. The spiral cooperation between the nut 3 and the screw makes the frame 2 and the display screen 1 fixedly connected. At this time, the frame 8 is fitted with the wall, and the frame 8 is penetrated by bolts. The connection between the frame 8 and the wall is completed through the connection between the bolts and the wall. When the display screen 1 is pulled to move, the moving display screen 1 pulls the first rotating plate 6 to rotate through the connecting frame 5 at the center of the frame 2, and the rotating and moving first rotating plate 6 pulls the second rotating plate 7 to rotate. The movement of the display screen 1 is facilitated by the rotation of the first rotating plate 6 and the second rotating plate 7. At the same time, when the display screen 1 is rotated, the display screen 1 rotates at the front side end of the first rotating plate 6 using the connecting frame 5 at the center of the frame 2.

An insertion rod 11 is inserted at the top and bottom of the protruding rod 10. A first spring 12 is provided inside the inner groove. The protruding rod 10 is connected to the inner side of the inner groove by the first spring 12. The second rotating plate 7 includes two side plates, and the two protruding rods 10 correspond to the two side plates one by one. The elastic force of the first spring 12 makes the protruding rod 10 pass through the rear end of the side plate, and a damping ring 9 is sleeved on the outer side of the circumference of the protruding rod 10. The rod 11 is pressed, and the rod 11 gradually enters the inner groove of the convex rod 10 under the action of pressure, and the inwardly moved rod 11 cooperates with the first spring 12 to squeeze the inner groove until the rod 11 completely enters the inner groove, and the convex rod 10 is placed between the two side plates of the second rotating plate 7. The pressure applied to the rod 11 is released, and the elastic force of the first spring 12 makes the rod 11 extend out of the inner groove until the rod 11 passes through the rear end of the side plate, and the rotating second rotating plate 7 rotates on the surface of the rod 11. At this time, the damping ring 9 provides rotation restriction for the rotation of the second rotating plate 7. The rod 11 is limited by the elastic force of the first spring 12, so that the second rotating plate 7 can be disassembled from the surface of the convex rod 10 at any time, and the disassembled display screen 1, the first rotating plate 6 and the second rotating plate 7 can be repaired, and the repaired display screen 1 can be installed on the convex rod 10.

After the connecting frame 5 uses the insertion frame 13 to pass through the center of the slide plate 14, when the display screen 1 is pushed up and down, since the wall limits the connecting frame 5 in the vertical direction through the second rotating plate 7 and the first rotating plate 6, the moving display screen 1 uses the side rods 15 of the frame plate 2 to move up and down inside the slide plate 14. When the frame plate 2 moves up, the upwardly moving frame plate 2 uses the top surface of the vertical groove to cooperate with the slide plate 14 to pull the second spring 16 at the top, and the bottom surface of the vertical groove cooperates with the slide plate 14 to squeeze the second spring 16 at the bottom; when the frame plate 2 moves down, the downwardly moving frame plate 2 uses the top surface of the vertical groove to cooperate with the slide plate 14 to squeeze the second spring 16 at the top, and the bottom surface of the vertical groove cooperates with the slide plate 14 to pull the second spring 16 at the bottom, so that the display screen 1 uses the frame plate 2 to move up and down on the outside of the slide plate 14, and the second spring 16 provides resistance for the movement of the frame plate 2 to prevent the frame plate 2 from moving too fast and causing impact damage to the vertical groove of the frame plate 2 and the slide plate 14.

[0021] Grooves 17 are provided on both inner side walls of the vertical groove, and elastic blocks 18 are fixed at the centers of both sides of the slide plate 14. The outer ends of the elastic blocks 18 are slidably engaged in the grooves 17, and the static friction between the outer side of the elastic block 18 and the grooves 17 is greater than the elastic force of the second spring 16. When the shelf 2 moves up and down, the grooves 17 of the vertical grooves move up and down synchronously on the surface of the elastic block 18 until the shelf 2 moves up or down to a suitable position, and then the driving force applied to the display screen 1 is released. At this time, the static friction between the outer side of the elastic block 18 and the grooves 17 prevents the shelf 2 from moving up and down, which facilitates the real-time adjustment of the position of the display screen 1 in the vertical direction, and facilitates the display screen 1 to display the 3D animation teaching process for students of different heights.

[0022] exist Figure 6 A through hole corresponding to the plug-in frame 13 is provided at the center of the skateboard 14, and a pressure rod 19 is inserted into the top and bottom ends of the skateboard 14, and a ring piece 20 is fixed to the inner end of the pressure rod 19. The inner side wall of the through hole circumference is provided with a ring groove corresponding to the ring piece 20, and an elastic member 21 is sleeved on the surface of the pressure rod 19, and the outer end of the pressure rod 19 is connected to a circular plate, the outer end of the elastic member 21 is connected to the circular plate, and the inner end of the elastic member 21 is connected to the skateboard 14. The circular plate pulls the pressure rod 19 to move, and the circular plate gradually moves away from the slide plate 14 during the movement. The moving circular plate cooperates with the slide plate 14 to pull the elastic member 21 on the surface of the pressure rod 19 until the moving pressure rod 19 drives the ring sheet 20 to enter the annular groove of the through hole. After the plug-in frame 13 of the connecting frame 5 is correspondingly plugged into the through hole, the pulling force applied to the circular plate is released, and the elastic force of the elastic member 21 causes the pressure rod 19 to move inward. The inwardly moved pressure rod 19 uses the ring sheet 20 to squeeze the plug-in frame 13, and the elastic force of the elastic member 21 is convenient for limiting the rotation of the slide plate 14.

[0023] exist Figure 6 and Figure 7In the embodiment, a plurality of ring strips 22 are arranged inside the inserting frame 13, an inner slide groove corresponding to the ring strip 22 is arranged inside the inserting frame 13, a convex plate 23 penetrating the inserting frame 13 is fixed to the outer side surface of the circumference of the ring strip 22, a side strip is fixed to the outer end of the convex plate 23, and the elastic force of the elastic member 21 makes the inner concave surface of the ring sheet 20 fit with the outer side surface of the side strip, a plurality of ring strips 22 are sleeved with a ring 24 on the outer side, an inner groove corresponding to the ring 24 is arranged on the inner side wall of the circumference of the inner slide groove, and the ring 24 is made of elastic rubber material. A push rod 25 is inserted into the front end of the rack 13, a patch is fixed to the front end of the push rod 25, and the front side of the patch is in contact with the rear side of the display screen 1, the rear end of the push rod 25 is inside the inner slide groove of the rack 13, a frustum 26 is fixed to the rear end of the push rod 25, the diameter of the rear end face of the frustum 26 is larger than the diameter of the front end face, and the inner side wall of the front end of the ring strip 22 is provided with an inclined surface 27 corresponding to the frustum 26. When the rubber ring 24 contracts, it pulls multiple ring strips 22 closer to each other, and the moving ring strips 22 pull the convex plate 23 into the inner slide groove. The inwardly moving convex plate 23 drives the side strips close to the rack 13 until the inner concave surface of the side strip fits with the outer circumferential surface of the rack 13. After the rack 13 is correspondingly inserted into the through hole of the slide plate 14, the moving rack 13 gradually approaches the rear side of the display screen 1 until the patch at the front end of the push rod 25 fits with the rear side of the display screen 1. At this time, the side strip on the outer side of the convex plate 23 is inside the annular groove of the through hole, and the side strip corresponds to the ring piece 20.

[0024] The nut 3 is screwed, and the spiral effect of the nut 3 and the screw makes the frame 2 approach the display screen 1. The moving frame 2 cooperates with the rubber ring 4 on the surface of the extruding screw. The moving frame 2 uses the slide plate 14 to drive the insertion frame 13 to approach the display screen 1. The reaction force of the back side of the display screen 1 facing the sticking plate makes the push rod 25 gradually enter the inside of the insertion frame 13. The moving push rod 25 pushes the round table 26 to approach the ring strip 22 until the ring inclined surface of the round table 26 fits with the inclined surface 27 of the ring strip 22, and the push rod 25 continues to move inward. At this time, the round table 26 slides on the surface of the inclined surface 27 using the ring inclined surface, and the ring inclined surface uses the inclined surface 27 to separate multiple ring strips 22. Multiple ring strips 22 open the sleeve 24 during the separation process. At this time, the ring strip 22 uses the convex plate 23 to drive the side strip away from the insertion frame 13 until the outer side surface of the side strip circumference fits with the inner concave surface of the ring sheet 20. At this time, multiple convex plates 23 cooperate with the annular groove to prevent the insertion frame 13 from being separated from the through hole of the slide plate 14.

[0025] When the display screen 1 is rotated, the display screen 1 makes the skateboard 14 rotate on the surface of the insertion frame 13 through the side rod 15 of the frame plate 2. The rotating skateboard 14 uses the ring piece 20 at the inner end of the pressure rod 19 to rotate on the outer side surfaces of multiple side strips. The elastic force of the elastic member 21 makes the inner concave surface of the ring piece 20 fit tightly with the outer side surface of the side strip. The rotation of the ring piece 20 and the side strip is limited, which makes it convenient to rotate the display screen 1 and to display 3D animations at different angles on the display screen 1.

[0026] The present invention also provides a 3D animation teaching system, which includes the 3D animation teaching system display device as described above.

[0027] Working principle of the present invention: Reference Figures 1 to 7 As shown, a suitable frame plate 2 is selected according to the shape of the display screen 1, and the frame plate 2 is aligned with the rear side of the display screen 1, and the rubber ring 4 is sleeved on the surface of the screw. At this time, multiple screws on the rear side of the display screen 1 correspond to penetrate the frame plate 2, and the nut 3 is spirally sleeved on the rear end of the screw. The spiral cooperation between the nut 3 and the screw makes the frame 2 and the display screen 1 fixedly connected. At this time, the frame 8 is fitted with the wall, and the frame 8 is penetrated by bolts. The connection between the frame 8 and the wall is completed through the connection between the bolts and the wall. When the display screen 1 is pulled to move, the moving display screen 1 pulls the first rotating plate 6 to rotate through the connecting frame 5 at the center of the frame 2, and the rotating and moving first rotating plate 6 pulls the second rotating plate 7 to rotate. The movement of the display screen 1 is facilitated by the rotation of the first rotating plate 6 and the second rotating plate 7. At the same time, when the display screen 1 is rotated, the display screen 1 rotates at the front side end of the first rotating plate 6 using the connecting frame 5 at the center of the frame 2. Since the damping ring 9 is embedded in the hinged position, the display screen 1 is conveniently limited after movement and rotation through the limitation of the damping ring 9. When displaying 3D animation teaching on the display screen 1, it is convenient to adjust the position of the display screen 1, and can provide a comprehensive display effect for students in different positions.

[0028] When the rubber ring 24 contracts, it pulls multiple ring strips 22 closer to each other, and the moving ring strips 22 pull the convex plate 23 into the inner slide groove. The inwardly moving convex plate 23 drives the side strips close to the rack 13 until the inner concave surface of the side strip fits with the outer circumferential surface of the rack 13. After the rack 13 is correspondingly inserted into the through hole of the slide plate 14, the moving rack 13 gradually approaches the rear side of the display screen 1 until the patch at the front end of the push rod 25 fits with the rear side of the display screen 1. At this time, the side strip on the outer side of the convex plate 23 is inside the annular groove of the through hole, and the side strip corresponds to the ring piece 20.

[0029] The nut 3 is screwed, and the spiral effect of the nut 3 and the screw makes the frame 2 approach the display screen 1. The moving frame 2 cooperates with the rubber ring 4 on the surface of the extruding screw. The moving frame 2 uses the slide plate 14 to drive the insertion frame 13 to approach the display screen 1. The reaction force of the back side of the display screen 1 facing the sticking plate makes the push rod 25 gradually enter the inside of the insertion frame 13. The moving push rod 25 pushes the round table 26 to approach the ring strip 22 until the ring inclined surface of the round table 26 fits with the inclined surface 27 of the ring strip 22, and the push rod 25 continues to move inward. At this time, the round table 26 slides on the surface of the inclined surface 27 using the ring inclined surface, and the ring inclined surface uses the inclined surface 27 to separate multiple ring strips 22. Multiple ring strips 22 open the sleeve 24 during the separation process. At this time, the ring strip 22 uses the convex plate 23 to drive the side strip away from the insertion frame 13 until the outer side surface of the side strip circumference fits with the inner concave surface of the ring sheet 20. At this time, multiple convex plates 23 cooperate with the annular groove to prevent the insertion frame 13 from being separated from the through hole of the slide plate 14.

[0030] When the display screen 1 is rotated, the display screen 1 makes the skateboard 14 rotate on the surface of the insertion frame 13 through the side rod 15 of the frame plate 2. The rotating skateboard 14 uses the ring piece 20 at the inner end of the pressure rod 19 to rotate on the outer side surfaces of multiple side strips. The elastic force of the elastic member 21 makes the inner concave surface of the ring piece 20 fit tightly with the outer side surface of the side strip. The rotation of the ring piece 20 and the side strip is limited, which makes it convenient to rotate the display screen 1 and to display 3D animations at different angles on the display screen 1.

[0031] When the frame 2 moves up and down, the groove 17 of the vertical groove moves up and down synchronously on the surface of the elastic block 18 until the frame 2 moves up or down to a suitable position, and then the driving force applied to the display screen 1 is released. At this time, the static friction between the outer side of the elastic block 18 and the groove 17 prevents the frame 2 from moving up and down, making it convenient to adjust the position of the display screen 1 in the vertical direction in real time, so that the display screen 1 can display 3D animation teaching process for students of different heights.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
