[0004] In view of this, the present invention provides a nano blackboard all-in-one machine with a fixed structure. The main technical problem to be solved is that in the existing device, when adjusting the height, two people usually adjust it synchronously from both sides at the same time. During the process, synchronization will occur, resulting in a long adjustment time, which is time-consuming and laborious.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixed-structure nano blackboard all-in-one machine, including a base, a bidirectional screw movably connected to the inner wall of the base, movable blocks threadedly connected to the outer walls of both ends of the bidirectional screw, a rotating groove opened at the top of the movable block, a connecting rod movably connected to the inner wall of the rotating groove, columns fixedly connected to the top of both ends of the base, a lifting rod provided inside the column, a lifting block fixedly connected to the top of the lifting rod, a fixed frame provided between the two lifting blocks, a positioning groove opened at the top of the fixed frame, and two positioning grooves, a blackboard provided at the front end of the fixed frame, a positioning strip provided on the back of the blackboard, and two positioning strips, the two positioning strips respectively located inside the two positioning grooves, a linkage groove opened at both ends of the bottom of the fixed frame, and the top ends of the two lifting rods respectively movably connected to the two linkage grooves.
[0006] By adopting the above technical solution, the lifting and lowering of the fixed frame can be achieved, thereby enabling the lifting and lowering of the smart screen. The adjustment speed is fast and the operation is simple.
[0007] As a further description of the above technical solution:
[0008] The outer walls of both columns are provided with limit grooves, and there are two limit grooves in each column. The outer walls of both lifting rods are fixedly connected with limit blocks, and there are two limit blocks in each rod. The limit blocks are located inside the limit grooves.
[0009] By adopting the above technical solution, the installation of the blackboard becomes convenient.
[0010] As a further description of the above technical solution:
[0011] The blackboard has an installation position inside, and the inner wall of the installation position has a slot, and there are multiple slots. Each of the multiple inner walls has a telescopic groove. The back of the blackboard has a connecting groove, and there are multiple connecting grooves. The multiple connecting grooves are respectively connected to the multiple telescopic grooves.
[0012] By adopting the above technical solution, the smart screen can be installed into the mounting position.
[0013] As a further description of the above technical solution:
[0014] Each of the multiple telescopic grooves has a spring fixedly connected to its inner wall, and a telescopic block is fixedly connected to the other end of each spring. A pull plate is fixedly connected to the outer wall of each telescopic block. The pull plate is located outside the blackboard, and the connection between the pull plate and the telescopic block is located inside the communicating groove.
[0015] By adopting the above technical solution, the smart screen pushed into the installation position is limited and fixed.
[0016] As a further description of the above technical solution:
[0017] The installation position is equipped with a smart screen. Both outer walls of the smart screen are provided with two card blocks. The card blocks are located inside the card slots and have locking slots inside. One end of the telescopic block extends into the locking slot.
[0018] By adopting the above technical solution, the smart screen can be accurately positioned after being pushed into the installation position.
[0019] As a further description of the above technical solution:

A support plate is fixedly connected to the bottom of the adjusting screw.
[0021] By adopting the above technical solution, it is convenient to move the entire device and fix its position.
[0022] By employing the above technical solution, the present invention provides a nano blackboard all-in-one machine with a fixed structure, which has at least the following beneficial effects:
[0023] 1. Compared with existing technologies, this fixed-structure nano blackboard all-in-one machine allows for height adjustment by rotating a handle connected to one end of a bidirectional screw, causing the bidirectional screw to rotate and two moving blocks to move synchronously in opposite directions. One end of a connecting rod movably connected to the top of each of the two moving blocks also moves synchronously in opposite directions, while the other ends of the two connecting rods simultaneously push the fixed frame upwards. Simultaneously, lifting blocks connected to both sides of the fixed frame, with lifting rods extending into the column at their bottom, move synchronously within the column as the fixed frame rises and falls. This improves the stability of the fixed frame during upward movement, provides a limit for its lifting, and facilitates height adjustment. The entire process can be completed by one person, avoiding asynchronous operations by two people, saving adjustment time, and offering simple, time-saving, and labor-saving operation.
[0024] 2. Compared with existing technologies, this fixed-structure nano blackboard all-in-one machine requires the smart screen to be installed on the blackboard before adjusting the height of the mounting frame. During installation, multiple clips connected to the smart screen are aligned with the multiple slots on the inner wall of the mounting position. The entire smart screen is then pushed into the mounting position. As the smart screen is pushed into the mounting position, the multiple clips squeeze the corresponding telescopic blocks, forcing the telescopic blocks into the telescopic slots. At this time, the spring is in a compressed state. When the smart screen is fully pushed into the mounting position, the locking slots in the clips align with the telescopic slots, and the spring rebounds, pushing one end of the telescopic block into the locking slot, thus achieving a quick installation of the smart screen. To disassemble the smart screen, the two pull plates in the same group are pulled relative to each other, causing the telescopic blocks to disengage from the locking slots, thus enabling the disassembly and maintenance of the smart screen.

Detailed Implementation
[0036] Reference Figure 1-9This utility model provides a fixed-structure nano blackboard all-in-one machine: It includes a base 1, with a bidirectional screw 2 movably connected to the inner wall of the base 1. Moving blocks 3 are threadedly connected to the outer walls of both ends of the bidirectional screw 2. A rotating groove 4 is formed at the top of each moving block 3, and a connecting rod 5 is movably connected to the inner wall of the rotating groove 4. Columns 6 are fixedly connected to both ends of the top of the base 1. A lifting rod 7 is installed inside each column 6, and a lifting block 8 is fixedly connected to the top of the lifting rod 7. A fixed frame 9 is located between the two lifting blocks 8. When adjusting the height of the all-in-one machine, rotating the handle connected to one end of the bidirectional screw 2 causes the bidirectional screw 2 to rotate, causing the two moving blocks 3 to move synchronously in opposite directions. This causes one end of the connecting rod 5, movably connected to the top of each moving block 3, to move synchronously in opposite directions, while the other ends of the two connecting rods 5 simultaneously act... The fixed frame 9 is pushed upward, and lifting blocks 8 are connected to both sides of the fixed frame 9. The bottom of the lifting blocks 8 is provided with lifting rods 7 that extend into the column 6. The lifting rods 7 move synchronously inside the column 6 as the fixed frame 9 rises and falls, which improves the stability of the fixed frame 9 during the upward movement and provides a limit for the lifting of the fixed frame 9, making it convenient to adjust the height of the all-in-one machine. The top of the fixed frame 9 is provided with positioning grooves 10, and there are two positioning grooves 10. The front end of the fixed frame 9 is provided with a blackboard 11, and the back of the blackboard 11 is provided with positioning strips 12, and there are two positioning strips 12. The two positioning strips 12 are located inside the two positioning grooves 10 respectively. The bottom ends of the fixed frame 9 are provided with linkage grooves 13, and the tops of the two lifting rods 7 are movably connected to the two linkage grooves 13 respectively.
[0037] The outer walls of the two columns 6 are provided with limit grooves 14, and there are two limit grooves 14 in each column. The outer walls of the two lifting rods 7 are fixedly connected with limit blocks 15, and there are two limit blocks 15 in each column. The limit blocks 15 are located inside the limit grooves 14.
[0038] The blackboard 11 has an internal mounting position 16. Multiple slots 17 are provided on the inner wall of the mounting position 16, and each inner wall has a telescopic groove 18. Multiple connecting grooves 19 are provided on the back of the blackboard 11, and each connecting groove 19 is connected to a telescopic groove 18. Springs 20 are fixedly connected to the inner walls of each telescopic groove 18, and telescopic blocks 21 are fixedly connected to the other end of each spring 20. Pull plates 22 are fixedly connected to the outer walls of the telescopic blocks 21, which are located outside the blackboard 11. The connection between the pull plates 22 and the telescopic blocks 21 is located inside the connecting grooves 19. A smart screen 23 is installed inside the mounting position 16. Two locking blocks 24 are provided on each of the two outer walls of the smart screen 23, and each locking block 24 is located inside the slot 17. Before adjusting the height of the mounting bracket 9... To install the smart screen 23 on the blackboard 11, multiple locking blocks 24 connected to the smart screen 23 are aligned with multiple slots 17 on the inner wall of the mounting position 16. The entire smart screen 23 is then pushed into the mounting position 16. During this process, the multiple locking blocks 24 squeeze the corresponding telescopic blocks 21, pushing the telescopic blocks 21 into the telescopic grooves 18. At this time, the spring 20 is in a compressed state. When the smart screen 23 is fully pushed into the mounting position 16, the locking grooves 25 in the locking blocks 24 align with the telescopic grooves 18, and the spring 20 rebounds, pushing one end of the telescopic block 21 into the locking groove 25. This achieves the process of quickly installing the smart screen 23. The locking grooves 25 are provided inside the locking blocks 24, and one end of the telescopic block 21 extends into the locking groove 25.
[0039] A connecting plate 26 is fixedly connected to the bottom of the base 1. Support legs 27 are fixedly connected to both ends of the connecting plate 26. Universal wheels 28 are installed at the bottom of both ends of the support legs 27. Adjusting screws 29 are threaded to both ends of the support legs 27. A support plate 30 is fixedly connected to the bottom of the adjusting screws 29. After the entire device is pushed to the designated position, the adjusting screws 29 are rotated to move the support plate 30 down until the bottom of the support plate 30 contacts the ground, thereby maintaining the stability of the entire device and making it suitable for different ground conditions.
[0040] Working principle: First, push the entire device to the designated position, then rotate the adjusting screw 29 to move the support plate 30 down until the bottom of the support plate 30 contacts the ground, thus maintaining the stability of the entire device and adapting to different ground conditions. Before adjusting the height of the fixing frame 9, the smart screen 23 needs to be installed on the blackboard 11. When installing the smart screen 23, align the multiple locking blocks 24 connected to the smart screen 23 with the multiple locking slots 17 opened on the inner wall of the mounting position 16. Then, push the entire smart screen 23 into the mounting position 16. During the process of pushing the smart screen 23 into the mounting position 16, the multiple locking blocks 24 squeeze the corresponding telescopic blocks 21, squeezing the telescopic blocks 21 into the telescopic groove 18. At this time, the spring 20 is in a compressed state. When the smart screen 23 is completely pushed into the mounting position 16, the locking slots 25 opened in the locking blocks 24 and the telescopic grooves... After the position of 18 is aligned, the spring 20 rebounds, pushing one end of the telescopic block 21 into the locking groove 25, realizing the process of quickly installing the smart screen 23. When adjusting the height of the all-in-one machine, the handle connected to one end of the bidirectional screw 2 is rotated to drive the bidirectional screw 2 to rotate, so that the two moving blocks 3 move synchronously in opposite directions. The ends of the connecting rods 5 that are movably connected to the top of the two moving blocks 3 move synchronously in opposite directions, while the other ends of the two connecting rods 5 act simultaneously to push the fixed frame 9 to move upward. At the same time, the lifting blocks 8 are connected to both sides of the fixed frame 9. The bottom of the lifting block 8 is provided with a lifting rod 7 that extends into the column 6. The lifting rod 7 moves synchronously inside the column 6 with the lifting of the fixed frame 9, which improves the stability of the fixed frame 9 during the upward movement and provides a limit for the lifting of the fixed frame 9, making it convenient to adjust the height of the all-in-one machine. The whole process can be achieved by only one person.
