[0029] 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.

[0030] Reference Figure 1-4 The utility model provides an embodiment: comprising a sphere 1, a mounting rod 2 is fixedly mounted on the top of the sphere 1, a round rod 7 is provided at the bottom of the sphere 1, four groups of discs 3 are fixedly mounted on the surface of the round rod 7, a mounting frame 4 is provided on the inner side of each two groups of discs 3, a connecting component 5 is provided on the surface of the round rod 7; a placement groove 6 is provided inside the round rod 7;

[0031] The connecting component 5 is used to limit the installation frame 4 to prevent the installation frame 4 from shaking. First, the installation rod 2 is installed to the required position, and then the sphere 1 and the installation rod 2 are fixed at this time. Then, the installation frame 4 is placed inside the disc 3. Finally, the installation frame 4 and the disc 3 are limited by the connecting component 5. At this time, the installation of parts such as the installation rod 2 can be realized, and the installation of the bolt ball grid ceiling is achieved.

[0032] Reference Figure 1-4The connecting assembly 5 includes a circular block 51, the bottom of the circular block 51 contacts the top of the mounting frame 4, a circular block 52 is fixedly installed on the top of the circular block 51, a sliding ring 53 is slidably installed on the surface of the round rod 7, and a connecting rod 54 is rotatably installed on the surface of the sliding ring 53. The bottom of the connecting rod 54 is fixedly installed on the top of the circular block 52. Through the mutual cooperation of the circular block 51, the circular block 52, the sliding ring 53 and the connecting rod 54, the sliding ring 53 can be pressed toward the bottom, and the sliding ring 53 drives the connecting rod toward the bottom. 54 moves toward the bottom, the connecting rod 54 moves toward the bottom to drive the circular block 51 and the circular block 52 to move toward the bottom, the circular block 51 moves toward the bottom to limit the installation frame 4, and finally the bolt ball grid frame and the installation frame 4 to be installed can be fixed by bolts, thereby realizing the installation of the bolt ball grid frame, and a rotating disk 55 is rotatably installed on the inner side of each two groups of discs 3, and the inner side of the rotating disk 55 and the outer side of the installation frame 4 are fixedly installed. By setting the rotating disk 55, a group of installation frames 4 can be pushed The rotation of the rotating disk 55 drives the four groups of mounting frames 4 to rotate, thereby realizing the angle adjustment of the mounting frame 4, which is convenient for installing the bolt ball grid frame in different positions. The connecting assembly 5 also includes a limit block 56, the bottom of the limit block 56 contacts the top of the sliding ring 53, and the limit block 56 is located inside the placement groove 6. There are five limit blocks 56. Through the setting of the limit block 56, when the sliding ring 53 moves to the bottom of the limit block 56, the limit block 56 can be pushed outward. The limit block 56 moves outward so that its bottom contacts the top of the sliding ring 53, thereby limiting the sliding ring 53. A spring 57 is fixedly installed on the inner wall of the placement groove 6. The outer end of the spring 57 is fixedly installed on the inner side of the limit block 56. Through the setting of the spring 57, the limit block 56 can always bear the elastic force of the spring 57, thereby making the limit block 56 more stable when in contact with the sliding ring 53, and avoiding the sliding ring 53 from being reset to the top during work.

[0033] Reference Figure 1-4 , a connecting rod 58 is fixedly installed at the bottom of the sphere 1, and a cover plate 59 is fixedly installed at the bottom of the connecting rod 58. The cover plate 59 and the round rod 7 are threadedly installed. Through the mutual cooperation of the connecting rod 58 and the cover plate 59, the top of the round rod 7 can be brought into contact with the bottom of the cover plate 59. At this time, the round rod 7 can be rotated, and the round rod 7 is rotated to enter the inside of the cover plate 59, so that the installation of the cover plate 59 can be achieved. A limiting ring 510 is fixedly installed on the surface of the round rod 7, and the top of the limiting ring 510 is in contact with the bottom of the sliding ring 53. Through the setting of the limiting ring 510, the sliding ring 53 can be limited to prevent the sliding ring 53 from moving too far to the bottom. At this time, the limiting block 56 has a poor limiting effect on the sliding ring 53.

[0034] Working principle: First, fix the mounting rod 2 on the beam, and then place the round rod 7 to the bottom of the cover plate 59. When the top of the round rod 7 contacts the bottom of the cover plate 59, the round rod 7 can be rotated to enter the inside of the cover plate 59, thereby realizing the installation of the cover plate 59. Then, when any group of mounting frames 4 is rotated, the rotating disk 55 can be driven to rotate. The rotation of the rotating disk 55 will drive the four groups of mounting frames 4 to rotate, thereby realizing the angle adjustment of the mounting frames 4. After the angle of the mounting frames 4 is adjusted, the sliding ring 53 can be pushed toward the bottom, and the sliding ring 53 drives the connecting rod 54 to move toward the bottom. The connecting rod 54 moves toward the bottom, driving the circular block 51 and the circular block 52 to move toward the bottom. The circular block 51 moves toward the bottom to limit the installation frame 4. When the sliding ring 53 and the limit block 56 contact, the limit block 56 will first move inward to enter the placement groove 6. Then, when the sliding ring 53 and the limit block 56 are disengaged, the limit block 56 is subjected to the elastic force of the spring 57, which will make the bottom of the limit block 56 contact the top of the sliding ring 53, thereby limiting the position of the card plate. Finally, the bolt ball grid frame to be installed and the installation frame 4 can be fixed by bolts, thereby realizing the installation of the bolt ball grid frame.
