[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Example 1

[0031] Please refer to Figure 1-Figure 4 , a flipped classroom tool, which is used in the field of classroom teaching tools, including:

[0032] Two support frames 1, one side of each support frame 1 is provided with a slide groove 2, the inside of each of the two slide grooves 2 is slidably connected with a slide rod 3, a blackboard 4 is rotatably connected between the two slide rods 3 through a rotating shaft, a mounting rod 5 is fixedly arranged between the two slide rods 3, and the mounting rod 5 is arranged at the bottom of the blackboard 4;

[0033] A light blocking mechanism is arranged on the top of the blackboard 4 to block light from the blackboard 4;

[0034] The collecting mechanism is arranged on the mounting rod 5 and is used for collecting and cleaning the chalk dust on the blackboard 4 .

[0035] A slot is provided on one side of each slide bar 3 , a spring is fixedly mounted on one side of the inner wall of the slot, an insert block is fixedly provided on one end of the spring, and a plurality of slots for inserting the insert blocks are provided on one side of the support frame 1 .

[0036] The above technical scheme can achieve the effect of pressing the two plug blocks so that the plug blocks move into the slots under the compression of the springs, and then move the blackboard 4. The sliding bars 3 fixed on both sides of the blackboard 4 will slide in the corresponding sliding grooves 2, so that the blackboard 4 can be slid and adjusted to a suitable height for students to watch and study. After the blackboard 4 slides to a suitable height position, since a plurality of plug holes are provided on one side of the support frame 1, the plug blocks will be plugged into the plug holes of corresponding heights under the action of the springs, which is beneficial to limit and fix the sliding bars 3 and the blackboard 4, and prevent the sliding bars 3 from sliding freely inside the sliding grooves 2, thereby improving the firmness of the blackboard 4. The light blocking mechanism can block light for the blackboard 4, and prevent the blackboard 4 itself from reflecting light during use, thereby affecting students' viewing of foreign languages ​​on the blackboard. The chalk dust can be collected and stored by the collecting mechanism, which is beneficial to uniformly clean and process the collected and stored chalk dust, thereby improving the convenience and technical effect.

[0037] The light blocking mechanism includes a blocking cover 9 for blocking light from the blackboard 4. The bottom of the blocking cover 9 is rotatably connected to two rotating rods 10 through a rotating shaft. The outer walls of the two rotating rods 10 are fixedly sleeved with anti-slip sleeves 11. The top ends of the two sliding rods 3 are fixedly sleeved with internal threaded tubes 8. The outer walls of the two rotating rods 10 are provided with external threads 12 threadedly connected to the internal threaded tube 8. By rotating the two rotating rods 10 at the same time, the anti-skid sleeve 11 sleeved on the outer wall of the rotating rod 10 can increase the anti-skid property with the professor's palm, facilitate rotation and use, and improve convenience. At the same time, the top of the rotating rod 10 and the blocking cover 9 will be rotationally connected through the rotating shaft, and the external thread 12 on the outer wall of the rotating rod 10 will be threadedly connected with the internal threaded tube 8, and then the rotating rod 10 can be threadedly installed in the internal threaded tube 8, so that the blocking cover 9 is installed on the top of the blackboard 4, and the effect of convenient disassembly is also achieved. The blocking cover 9 can block light for the blackboard 4, preventing the blackboard 4 itself from reflecting light during use, which affects students' viewing of foreign languages ​​on the blackboard, avoids unclear viewing, affects students' learning progress, and brings troubles to students, thereby improving applicability.

[0038] The collecting mechanism includes an ash collecting frame 13, which is fixedly arranged on one side of the mounting rod 5. A mobile frame 14 is slidably connected inside the ash collecting frame 13, and a cleaning pad 15 is clamped and installed on the inner wall of the mobile frame 14. Two limit plates 16 for limiting the mobile frame 14 are fixedly arranged on the top of the ash collecting frame 13, and a through hole 17 is opened on the bottom side of the inner wall of the ash collecting frame 13. A collection box 20 corresponding to the through hole 17 is arranged at the bottom of the mounting rod 5, and a mounting block 19 is fixedly arranged on the top of the collection box 20. A mounting groove 18 for sliding installation of the mounting block 19 is opened on one side of the mounting rod 5. Chalk dust can be collected by the ash collecting frame 13. When there is too much chalk dust in the ash collecting frame 13, the movable frame 14 is pushed to drive the cleaning pad 15 installed on the inner wall to move. The limiting plate 16 fixed on the top of the ash collecting frame 13 can limit the movable frame 14, so that the cleaning pad 15 can fit tightly with the bottom side of the inner wall of the ash collecting frame 13. When the chalk dust is pushed to the through opening 17, the chalk dust will automatically fall into the corresponding collection box 20 through the through opening 17, and then the chalk dust in the ash collecting frame 13 can be cleaned. The chalk dust can be stored in the collection box 20. The collection box 20 can be disassembled and removed by using the sliding connection between the mounting block 19 and the mounting groove 18, which is conducive to unified processing of the collected and stored chalk dust and improves convenience.

[0041] Please refer to Figure 1-Figure 3A threaded rod 6 is passed through the bottom of the mounting rod 5, and the outer wall of the threaded rod 6 is connected to the inner thread of the mounting rod 5. The top and bottom of the blackboard 4 are both provided with threaded holes 7 for the threaded rod 6 to be threadedly connected.

[0042] The above technical solution can achieve the purpose of utilizing the rotational connection between the blackboard 4 and the sliding rods 3 on both sides, so that the blackboard 4 can be easily flipped over so that the professor can use the other side. At the same time, the threaded rotating rod 6 is rotated and threadedly connected to the corresponding threaded hole 7, so that the blackboard 4 can be locked and fixed, thereby improving the stability of the blackboard 4 after flipping, and facilitating the professor to use the technical effect.

[0043] Please refer to Figure 1 A cross bar 21 is fixedly arranged between the two support frames 1, and the cross bar 21 is arranged at the bottom of the mounting rod 5. A support plate 22 is fixedly arranged at the bottom of the two support frames 1, and two universal wheels are fixedly installed at the bottom of each support plate 22.

[0044] The above technical solution can achieve the goal of supporting the device through the support plate 22 and the universal wheel, making it easy to move the device. The setting of the cross bar 21 enhances the stability between the support frames 1.
