[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 7 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] A prefabricated building wall structure includes: a main board 1; secondary boards 2 are provided on both sides of the main board 1, and fixing strips 3 are fixedly connected to both sides of the secondary boards 2. Pins 4 are fixedly connected to both ends of the fixing strips 3. Mounting sleeves 5 are provided on the main board 1 near the pins 4, and the mounting sleeves 5 are respectively fitted onto the outer surface of the pins 4; a linkage mechanism 6 is provided on the side of the mounting sleeves 5 near the main board 1 for quick assembly and disassembly of the main board 1 and the secondary boards 2; a disassembly and assembly mechanism 7 for easy hanging and picking up of items is provided on one side of both the main board 1 and the secondary boards 2. The user controls the two mounting sleeves 5 on both sides of the main board 1 to move away from each other through the linkage mechanism 6, then places the two secondary boards 2 on both sides of the main board 1, and finally controls the mounting sleeves 5 to move towards the pins 4 simultaneously through the linkage mechanism 6, so that they fit onto the outside of the pins 4, thereby achieving the purpose of quick installation of the secondary boards 2 through the pins 4 and the fixing strips 3.

[0029] like Figure 7 As shown, the linkage mechanism 6 includes: a connecting block 8 fixedly connected to the side of the mounting sleeve 5 near the main board 1; a slider 9 fixedly connected to the side of the connecting block 8 away from the mounting sleeve 5; and a corresponding stroke groove 10 provided on the main board 1 near the slider 9 and the connecting block 8; two fixing blocks 11 fixedly connected to the side of the slider 9 away from the connecting block 8; the two fixing blocks 11 are fixedly connected to each other by a first rotating shaft 12; a linkage rod 13 is rotatably connected to the outer surface of the middle part of the first rotating shaft 12; and a second rotating shaft 13 is rotatably connected to the end of the linkage rod 13 away from the first rotating shaft 12. 4. Four second rotating shafts 14 are respectively fixed inside the two moving blocks 15; a rotating mechanism 16 is provided at the center of the main board 1 to control the relative movement of the two moving blocks 15. The user controls the two moving blocks 15 to move away from each other through the rotating mechanism 16. While the moving blocks 15 move, they drive the second rotating shafts 14. The second rotating shafts 14 press one end of the linkage rod 13, so that the other end of the linkage rod 13 presses and pushes the first rotating shaft 12. The first rotating shaft 12 drives the fixed block 11, and the fixed block 11 drives the slider 9. The slider 9 drives the mounting sleeve 5 to move away from each other through the connecting block 8.

[0030] like Figures 2 to 7As shown, the rotating mechanism 16 includes: a circular plate 17 disposed at the center of the main plate 1; two arc-shaped grooves 18 formed inside the circular plate 17; cylindrical pins 19 disposed inside each arc-shaped groove 18; the two cylindrical pins 19 being fixedly connected to the moving block 15; a limit block 20 being fixedly connected to the side of the moving block 15 away from the cylindrical pins 19; and matching limit grooves 21 formed on the main plate 1 near the limit blocks 20; the limit blocks 20 being slidably connected to the limit grooves 21. A third rotating mechanism is fixedly connected at the center of the circular plate 17. Shaft 22, the end of the third rotating shaft 22 away from the circular plate 17 passes through the main board 1 and extends to the knob 23. The knob 23 is fixedly connected to the third rotating shaft 22, and the third rotating shaft 22 is fixedly connected to the main board 1. When the user rotates the knob 23, the knob 23 drives the third rotating shaft 22, and the third rotating shaft 22 drives the circular plate 17 to rotate. While the circular plate 17 rotates, it pushes the cylindrical pin 19 through the arc groove 18. The cylindrical pin 19 drives the moving block 15. The two moving blocks 15 slide away from each other through the cooperation of the limiting block 20 and the limiting groove 21.

[0031] like Figure 7 As shown, each slider 9 has a sliding rod 24 slidably connected inside. Both ends of the sliding rod 24 are fixedly connected to the main board 1. A first spring 25 is provided between the slider 9 and the main board 1. The first spring 25 is respectively sleeved on the outer surface of the sliding rod 24. It can not only limit the slider 9 so that the slider 9 can slide flexibly on the surface of the sliding rod 24, but also push the slider 9 when the user releases the knob 23. This causes the two sliders 9 to move towards the pin 4 through the connecting block 8 and the mounting sleeve 5.

[0032] like Figure 1 As shown, both the main board 1 and the sub-board 2 are fixedly connected to ball bearing seats 26 on both sides of their bottom. The ball bearing seats 26 are equipped with movable balls 27. When the user adjusts the angle between the sub-board 2 and the main board 1 with the mounting sleeve 5 as the center, the main board 1 or the sub-board 2 can rotate flexibly.

[0033] like Figure 3As shown, the disassembly and assembly mechanism 7 includes: a perforated plate 28 is provided on one side of both the main plate 1 and the sub-plate 2; a plurality of mounting pins 29 are evenly arranged inside the perforated plate 28; steel balls 30 are provided at the four corners of the mounting pins 29 near the end of the perforated plate 28; a matching ball groove 31 is provided on the perforated plate 28 near the steel balls 30; a second spring 32 is provided on the side of the steel balls 30 away from the mounting pins 29, and the second springs 32 are respectively located inside the ball grooves 31; a matching slot 35 is provided on the outer surface of the mounting pins 29 near the steel balls 30, allowing the user to hang items as needed. The user can freely install and remove the mounting pin 29 on the perforated plate 28 by adjusting the size of the product. During installation, the user inserts the mounting pin 29 into the interior of the perforated plate 28. At the same time as the mounting pin 29 is inserted, it pushes the steel ball 30, causing the steel ball 30 to enter the interior of the ball groove 31. When the mounting pin 29 is fully inserted into the interior of the perforated plate 28, the second spring 32 pushes the steel ball 30, causing a small part of the steel ball 30 to move into the slot 35 on the surface of the mounting pin 29, thereby fixing the mounting pin 29. During removal, the user can forcefully pull out the mounting pin 29 inside the perforated plate 28.

[0034] like Figure 3 As shown, decorative panels 33 are provided between the perforated panel 28, the main panel 1, and the sub-panel 2. The decorative panels 33 are all fixedly connected to the perforated panel 28. The side of the decorative panel 33 away from the perforated panel 28 is fixedly connected to a sound insulation panel 34. The sound insulation panel 34 is fixedly connected to the main panel 1 and the sub-panel 2 respectively. The decorative panel 33 improves the aesthetics of the partition wall surface, and the sound insulation panel 34 improves the overall sound insulation effect of the partition wall.

[0035] Working principle: When assembling the partition wall, the user rotates knob 23, which drives the third rotating shaft 22. The third rotating shaft 22 drives the circular plate 17 to rotate. While rotating, the circular plate 17 pushes the cylindrical pin 19 through the arc groove 18. The cylindrical pin 19 drives the moving block 15. The two moving blocks 15 slide away from each other through the cooperation of the limiting block 20 and the limiting groove 21. While moving, the moving block 15 drives the second rotating shaft 14. The second rotating shaft 14 presses one end of the linkage rod 13, causing the other end of the linkage rod 13 to press and push the first rotating shaft 12. The first rotating shaft 12 drives the fixing block 11, which drives the slider 9. The slider 9 drives the mounting sleeve 5 away from each other through the connecting block 8. Then, the two sub-plates 2 are placed on both sides of the main plate 1. The knob 23 is released, and the first spring 25 pushes the slider 9, causing the two sliding... Block 9 causes the slider 9 to move the mounting sleeve 5 towards the pin 4 via the connecting block 8, thereby allowing the mounting sleeve 5 to be fitted onto the surface of the pin 4. The user can then adjust the angle between the main board 1 and the sub-board 2 by cooperating with the pin 4 and the mounting sleeve 5. This not only allows the user to quickly assemble and disassemble the main board 1 and the sub-board 2, but also allows for free adjustment of the angle between the main board 1 and the sub-board 2 according to the environment of the installation site after installation. This enables the partition wall to be installed arbitrarily according to the needs of the site environment, solving the problem that although the existing prefabricated building wall structure can quickly install and disassemble the partition wall, it can only be installed in parallel. Since the installation environment of the partition wall is not necessarily rectangular and may have corners, the existing partition wall cannot be adjusted according to the installation environment, resulting in poor practicality.

[0036] Users can freely install and remove the mounting pins 29 on the perforated plate 28 according to the volume of the items to be hung. During installation, the user inserts the mounting pin 29 into the interior of the perforated plate 28. At the same time as the mounting pin 29 is inserted, it pushes the steel ball 30, causing the steel ball 30 to enter the ball groove 31. When the mounting pin 29 is fully inserted into the interior of the perforated plate 28, the second spring 32 pushes the steel ball 30, causing a small part of the steel ball 30 to move into the slot 35 on the surface of the mounting pin 29, thereby fixing the mounting pin 29. During disassembly, the user can forcefully pull out the mounting pin 29 inside the perforated plate 28. The decorative panel 33 improves the aesthetics of the partition wall surface, and the sound insulation panel 34 improves the overall sound insulation effect of the partition wall. It not only makes it convenient for users to hang items on the partition wall after installation, but also improves the overall aesthetics and sound insulation effect of the partition wall after installation, increases the versatility of the partition wall function, and solves the problem of the relatively simple functionality of the existing prefabricated building wall structure.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
