[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-8As shown, the present invention provides a technical solution: a bolted ball joint space frame structure, including a bolted ball joint body 1, on which a set of mounting grooves 2 are provided. The mounting grooves 2 facilitate the assembly of mounting sleeves 3. The mounting sleeves 3 are housed within the mounting grooves 2 and are fixedly connected to the bolted ball joint body 1 by screws. The installation of the mounting sleeves 3 facilitates assembly with the bolted ball joint body 1. When wear and stripping occur, it is convenient to replace worn parts without replacing the entire bolted ball joint body 1. Compared with existing technologies, this invention offers the advantage of more convenient assembly and replacement. A threaded post 4 is threadedly connected to the mounting sleeve 3. A connecting pipe 5 is fixedly connected to the upper end of the threaded post 4. An anti-detachment structure 6 is provided at the bottom end of the threaded post 4. The anti-detachment structure 6 limits the connection between the threaded post 4 and the mounting sleeve 3, preventing the threaded post 4 from detaching, thereby ensuring the stability of the bolted ball joint space frame. Compared with existing technologies, this invention is more efficient. Stable and easy to disassemble, the top of the connecting pipe 5 is fixedly connected to a clamping block 7, and a clamping sleeve 8 is fitted over the clamping block 7. The clamping sleeve 8 is fixedly connected to the clamping block 7 by an internal hex bolt. The clamping block 7 and the clamping sleeve 8 facilitate disassembly and assembly, providing greater flexibility. The upper end face of the clamping sleeve 8 is fixedly connected to a bearing sleeve 9, and a bearing plate 10 is fixedly connected inside the bearing sleeve 9. A steel pipe 11 is installed inside the bearing plate 10, and a fixing structure 12 is provided on the bearing plate 10 for internal support and fixing of the steel pipe 11. The fixing structure 12 facilitates the fixing of steel pipes 11 of different sizes, providing greater flexibility. Compared with welding, it can improve the efficiency of assembling the space frame. Each of the four support plates of the bearing sleeve 9 has a through hole, and a threaded sleeve 13 is fixedly connected in each through hole. A locking bolt 14 is threaded inside the threaded sleeve 13. By rotating the locking bolt 14, the outer wall of the steel pipe 11 can be pressed against it. Together with the fixing structure 12, it can effectively fix steel pipes 11 of different sizes, providing greater flexibility.

[0033] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, in a preferred embodiment, based on the above method, the anti-detachment structure 6 further includes a mounting frame 601 fixed to the bottom end of the threaded column 4. A rotating shaft 602 is rotatably connected inside the bottom end of the mounting frame 601. The top end of the rotating shaft 602 passes through the threaded column 4 and extends into the interior of the connecting pipe 5. A first worm gear 603 is fixedly connected to the top end of the rotating shaft 602. A first rotating rod 604 is rotatably connected to one side of the connecting pipe 5. A first worm 605, meshing with the first worm gear 603, is fixedly connected to one end of the first rotating rod 604 located inside the connecting pipe 5. A rotating head 606 is fixedly connected to the outer end of the first rotating rod 604. Four through holes are evenly opened on the outer peripheral sidewall of the mounting frame 601, and a connecting rod 607 is slidably connected to each of the four through holes. An anti-detachment plate 608 is fixedly connected to the outer end of the connecting rod 607. A rotating frame 609 is fixedly connected to the bottom of the rotating shaft 602. The four ends of the rotating frame 609 are rotatably connected to... A connecting rod 6010 is connected, and the outer end of the connecting rod 6010 is rotatably connected to the adjacent connecting rod 607. A hexagonal groove is opened in the rotating head 606. The cross-sectional shape of the anti-detachment plate 608 is arc-shaped. An anti-detachment groove matching the anti-detachment plate 608 is opened in the mounting sleeve 3. By rotating the rotating head 606, the first rotating rod 604 and the first worm gear 605 can be rotated. The rotation of the first worm gear 605 can cause the first worm wheel 603 to rotate. The rotation of the first worm wheel 603 drives the rotating shaft 602 to rotate. The rotation of the rotating shaft 602 causes the rotating frame 609 to rotate, thereby causing the connecting rod 6010 to drive the connecting rod 607 and the anti-detachment plate 608 to move outward, thereby limiting the threaded column 4 and preventing the threaded column 4 from loosening and coming off. Rotating the rotating head 606 in the opposite direction causes the anti-detachment plate 608 to retract inward, which is convenient for disassembly. The connecting rod 6010 is V-shaped.

[0034] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, in a preferred embodiment, based on the above method, the fixing structure 12 further includes a fixing plate 1201 disposed at the center of the top of the bearing sleeve 9. Multiple support rods 1202 are fixedly connected between the fixing plate 1201 and the bearing plate 10. A bidirectional screw 1203 is rotatably connected between the fixing plate 1201 and the bearing plate 10. Two moving heads 1204 are threadedly connected to the outer side of the bidirectional screw 1203. Four adjusting rods 1205 are rotatably connected to the outer side of each of the two moving heads 1204. A connecting block 1206 is rotatably connected to the end of each adjusting rod 1205 close to the bearing sleeve 9. A support plate 1207 is fixedly connected to the outer end of each adjacent connecting block 1206. The bottom end of the bidirectional screw 1203 penetrates the bearing plate 10 and is fixedly connected to a second worm gear 1208. A second rotating rod 1209 is rotatably connected to one end of the bearing sleeve 9. The inner end of the second rotating rod 1209... A second worm 1210 is fixedly connected to the end of the second rotating rod 1209 and meshes with the second worm gear 1208. A knob 1211 is fixedly connected to the outer end of the second rotating rod 1209. There are four support plates 1207, and each of the four support plates 1207 has a sliding column 1212 fixedly connected to its bottom end. A straight opening 1213 matching the sliding column 1212 is provided on the bearing plate 10. By rotating the knob 1211, the second rotating rod 1209 and the second worm 1210 are rotated, which in turn causes the second worm gear 1208 to rotate. The rotation of the second worm gear 1208 drives the bidirectional screw 1203 to rotate, which causes the moving head 1204 to move towards each other, thereby moving the adjusting rod 1205 and causing the support plate 1207 to move outward. This facilitates the internal support and fixation of the steel pipe 11. The sliding column 1212 and the straight opening 1213 facilitate the movement of the support plate 1207 and ensure the stability of the movement.

[0035] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, four protrusions 15 are evenly fixedly connected to the outer peripheral sidewall of the mounting sleeve 3, and slots 16 matching the protrusions 15 are opened in the mounting groove 2. The length of the protrusions 15 is less than the height of the mounting sleeve 3. The setting of the protrusions 15 and the slots 16 can improve the stability of the mounting sleeve 3, prevent the mounting sleeve 3 from rotating, and ensure the overall stability.

[0036] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, a waterproof cover 17 is fixedly connected to the outside of the connecting pipe 5, and an annular opening 18 matching the waterproof cover 17 is opened on the upper end face of the mounting sleeve 3; the waterproof cover 17 and the annular opening 18 can block external rainwater, prevent external rainwater from entering, and avoid the phenomenon of rusting of the threaded post 4.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, a rotating block 19 is fixedly connected to the outer peripheral sidewall of the connecting pipe 5. The rotating block 19 has a hexagonal cross-sectional shape, and anti-slip grooves are provided on the outer sidewall of the rotating block 19. The rotating block 19 facilitates the rotation of the connecting pipe 5 with the help of external equipment, thereby facilitating the installation of the threaded post 4. The anti-slip grooves can increase the friction.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, a set of drainage outlets 20 are evenly provided on the outer peripheral sidewall of the bearing sleeve 9, and the bottom surface of the drainage outlets 20 is at the same level as the inner bottom wall of the bearing sleeve 9; this facilitates the timely discharge of rainwater accumulated in the bearing sleeve 9 and avoids water accumulation.

[0039] Working principle: The corresponding mounting sleeve 3 is inserted into the mounting groove 2 according to the required installation position. Then, the mounting sleeve 3 is fixed to the bolt ball joint body 1 with screws. The threaded post 4 is screwed into the mounting sleeve 3, so that the mounting frame 601 abuts against the inside of the mounting sleeve 3 and is tightened. Then, with the help of an external electric device, the rotating head 606 is rotated. The rotation of the rotating head 606 causes the first rotating rod 604, the first worm gear 605, the first worm wheel 603, and the rotating shaft 602 to rotate. The rotation of the rotating shaft 602 causes the rotating frame 609 to rotate. The rotation of the rotating frame 609 causes the connecting rod 6010 to move, thereby causing the connecting rod 607 and the anti-detachment plate 608 to move outward, so that the anti-detachment plate 608 abuts against the anti-detachment groove inside the mounting sleeve 3. Finally, the clamping sleeve 8 is fitted onto the clamping block 7. The clamping block 7 and the clamping sleeve 8 are fixed by the internal hex bolts. Then, the steel pipe 11 is inserted into the fixing plate 1201, and the support plate 1207 is located inside the steel pipe 11. Rotating the knob 1211 causes the second rotating rod 1209, the second worm gear 1210, the second worm wheel 1208 and the double screw 1203 to work. The rotation of the double screw 1203 causes the two moving heads 1204 to move synchronously in the center. The movement of the moving heads 1204 drives the adjusting rod 1205 to move, which in turn causes the support plate 1207 to move outward synchronously, thereby internally supporting and fixing the steel pipe 11. Then, the clamping bolt 14 is rotated to rotate, thereby internally and externally pressing and fixing the steel pipe 11, which is convenient for fixing steel pipes 11 of different sizes, and also convenient for installation and disassembly.
