Description

Technical Field

[0001] The utility model relates to the technical field of multimedia teaching, in particular to an indoor interactive teaching device for smart education. Background Art

[0002] A smart classroom is a form of digital classroom and future classroom. It uses modern means to cut into the entire teaching process, making the classroom simple, efficient and intelligent, helping to develop students' independent thinking and learning abilities, and strengthening the interactivity between teachers and students. In the teaching process, teaching interaction is usually communication interaction, that is, information interaction, which can transfer knowledge. For the convenience of teaching, a multimedia display screen is usually installed on the blackboard. However, since the multimedia display screen is fixed to a place on the blackboard, the sight lines of the students on both sides of the front row are projected onto the multimedia display screen at an angle, making it difficult for the students on both sides of the front row to focus on the multimedia display screen, affecting the students' observation of the content displayed on the multimedia display screen, making it inconvenient to use. For this reason, we propose an indoor interactive teaching device for smart education. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 5, an indoor interactive teaching device for smart education, including an outer frame 1, a multimedia display screen mechanism is installed on the outer frame 1, and a writing board 4 is installed on the outer frame 1, the multimedia display screen mechanism includes a middle display screen 2, a side display screen 3, a connecting plate 7, and a locking pin 8. The backs of both sides of the middle display screen 2 are connected to the side display screens 3 through the connecting plates 7, and the middle display screen 2 and the side display screens 3 can rotate relative to each other. When the writing board 4 is fully extended, the middle display screen 2 can be pulled to move outside the outer frame 1, and the side display screens 3 can be rotated relative to the middle display screen 2, so that the side display screens 3 can be tilted, so that it can be displayed at multiple angles, and the side The upper and lower surfaces of the side display screen 3 away from the middle display screen 2 are fixedly connected with concentric and equicircular pins 6, and the pins 6 are movably connected to the inside of the front of the outer frame 1, so that the multimedia display screen mechanism can always be connected to the outer frame 1, and the side display screen 3 can be rotated on the outer frame 1 with the pins 6 as the rotating axis, ensuring its smooth deflection. The writing board 4 is movably connected to the outer frame 1, and the writing board 4 can slide to the front of the multimedia display screen mechanism. At the same time, one end of the writing board 4 can slide and extend out of the end of the outer frame 1. The writing board 4 can slide inside and outside the outer frame 1. When the writing board 4 moves outward, the display length of the outer frame 1 can be further extended.

[0026] See also Figures 1 to 8 A movable slide groove 11 is opened inside the front of the outer frame 1, the pin 6 is cylindrical, and the pin 6 is movably connected in the movable slide groove 11, so that the pin 6 can be relatively moved and rotated in the movable slide groove 11.

[0027] See also Figures 1 to 8 A semicircular fixed slide rail 10 is provided inside the front of the outer frame 1. The fixed slide rail 10 is located directly in front of the movable slide groove 11, and the writing board 4 is movably connected to the fixed slide rail 10 and matches it. Under the limitation of the fixed slide rail 10, the writing board 4 can slide stably.

[0028] See also Figures 1 to 11 An intercepting portion 14 is provided at one end of the writing board 4 close to the middle of the outer frame 1. The width of the intercepting portion 14 is greater than the overall width of the writing board 4. The intercepting portion 14 can abut against the inner wall of the outer frame 1 to prevent the writing board 4 from being completely inside the outer frame 1, thereby ensuring the connection of the writing board 4.

[0029] See also Figures 1 to 10The end of the writing board 4 away from the middle of the outer frame 1 is movably provided with a knob 5, and the knob 5 can be rotated at a fixed position on the writing board 4. One end of the knob 5 extends out of the front of the writing board 4, and the other end of the knob 5 extends into the interior of the writing board 4 and is threadedly connected to the supporting cylinder 13. When the knob 5 and the supporting cylinder 13 rotate relative to each other, the supporting cylinder 13 can move.

[0030] See also Figures 1 to 10 One end of the supporting cylinder 13 is movably connected to the inside of the writing board 4. The supporting cylinder 13 can move along a fixed track inside the writing board 4, so that the knob 5 and the supporting cylinder 13 can rotate relative to each other. The other end of the supporting cylinder 13 extends out of the back of the writing board 4, and the end of the supporting cylinder 13 extending out of the back of the writing board 4 can abut against the wall. Through the abutment between the supporting cylinder 13 and the wall, the writing board 4 can be supported, avoiding the extended end of the writing board 4 from being in a suspended state, thereby ensuring stable writing on the writing board 4.

[0031] See also Figures 1 to 9 The connecting plate 7 is arc-shaped, and arc-shaped slide grooves 12 are provided on the middle display screen 2 and the side display screen 3. The two ends of the connecting plate 7 are movably connected to the arc-shaped slide grooves 12 on the middle display screen 2 and the side display screen 3, respectively, so that the connecting plate 7 can be relatively rotated in the arc-shaped slide grooves 12, thereby enabling the middle display screen 2 and the side display screen 3 to rotate relative to each other.

[0032] See also Figures 1 to 9 The top and bottom of the connecting plate 7 are movably connected with a locking pin 8. One end of the locking pin 8 extends out of the connecting plate 7 and is hemispherical. The other end of the locking pin 8 extends into the connecting plate 7 and is fixedly connected with a spring 9. One end of the spring 9 is fixed to the inner wall of the connecting plate 7 under the action of the elastic force of the spring 9, so that the locking pin 8 can extend out of the connecting plate 7. A notch matching the hemispherical end of the locking pin 8 is opened in the arc-shaped slide groove 12. At the same time, the hemispherical end of the locking pin 8 can be plugged into the notch. When the locking pin 8 is plugged into the notch, the rotation position of the middle display screen 2 and the side display screen 3 can be limited, so that it can be stably in the adjusted position.

[0033] In summary, when the indoor interactive teaching device for smart education is in use, its writing board 4 can slide inside and outside the outer frame 1. When the writing board 4 moves outward, the display length of the outer frame 1 can be further extended, making it more convenient to use. When the writing board 4 is extended, the knob 5 is turned so that the knob 5 can rotate relative to the supporting cylinder 13, and then the supporting cylinder 13 can move, and then contact the wall to support the writing board 4. When the writing board 4 is fully extended, the middle display screen 2 can be pulled to move outside the outer frame 1, and the side display screen 3 can be rotated relative to the middle display screen 2, so that the side display screen 3 can be tilted, so that it can be displayed at multiple angles. When the middle display screen 2 and the side display screen 3 rotate relative to the connecting plate 7, under the action of the elastic force of the spring 9, the locking pin 8 can be plugged into the notch in the arc-shaped slide groove 12, thereby limiting the rotation position between the middle display screen 2 and the side display screen 3.
