[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 10 shown, the present invention provides a building daylighting roof installation structure, including; The connection frame 1 is made of aluminum alloy; The mounting hole 11 is opened on the outer wall of the connection frame 1; The connection piece 12 is L-shaped and made of stainless steel; The bolt 2 is threadedly installed inside the mounting hole 11; The cylinder 6 is fixedly installed at one end of the bolt 2; The nut 5 is threadedly installed on the outer wall of the cylinder 6; The fixing mechanism is arranged inside the bolt 2 and is used to strengthen the connection between the bolt 2 and the mounting hole 11; The limiting mechanism is arranged inside the cylinder 6 and is used to limit the nut 5; Among them, the fixing mechanism includes a fixing component and a positioning component. The fixing component has three groups, including a rotating block 31 rotatably installed inside the bolt 2. Four arc-shaped sliding grooves 311 are opened on the outer wall of the rotating block 31. A convex column 42 is slidably installed in the inner wall of each arc-shaped sliding groove 311. One end of each convex column 42 is fixedly installed with a rectangular column 4, and an arc-shaped plate 41 is fixedly installed at the outer end of each rectangular column 4. Four rectangular grooves 22 are opened on the outer wall of the bolt 2, and the four arc-shaped plates 41 are respectively slidably connected with the corresponding rectangular grooves 22; the positioning component includes a rotating column 3 rotatably installed inside the bolt 2. The rotating column 3 passes through the cylinder 6 and is rotatably connected with the cylinder 6. Three mounting round plates 21 are rotatably sleeved on the outer wall of the rotating column 3, and the three mounting round plates 21 are all fixedly connected with the inner wall of the bolt 2; four rectangular sliding grooves 211 are opened on the outer walls of the three mounting round plates 21, and each rectangular sliding groove 211 is respectively slidably connected with the corresponding rectangular column 4.

[0023] Adopt the above solution: By setting the fixing mechanism, the design of the rotating block 31 ensures the tight connection between the bolt 2 and the mounting hole 11 and provides additional supporting force. Four groups of arc-shaped chutes 311 are arranged on the outer wall of each rotating block 31, which not only enhances the cooperation with the convex column 42, but also enables the convex column 42 to move smoothly during rotation through the design of the arc-shaped chute 311, thus avoiding structural deviation caused by improper installation or uneven force. One end of each convex column 42 is fixedly installed with a rectangular column 4, and the design accuracy of the rectangular column 4 is extremely high, ensuring its perfect cooperation with the arc-shaped plate 41 and further strengthening the stability of the entire structure; The outer end of the rectangular column 4 is fixedly installed with an arc-shaped plate 41, which can achieve adaptive adjustment and fine-tuning through the sliding fit with the rectangular groove 22. The four arc-shaped plates 41 in the rectangular groove 22 ensure the stability of the rotating block 31 during movement and prevent system loosening or deviation caused by external force application. Therefore, this design not only improves the installation accuracy, but also makes the entire installation process faster and more efficient, reducing the influence of human error on the structural stability; The positioning component includes the rotating column 3 and its rotational connection with the cylindrical column 6. Through this structure, the rotating column 3 can provide continuous rotational support during installation, making the force distribution of the entire structural system more uniform and reducing the risk of local overload. The design of the rotating column 3 not only has excellent load-bearing capacity, but also can freely adjust the angle of the mounting circular plate 21 during rotation, thus effectively ensuring the stable operation of the rectangular column 4; Four rectangular chutes 211 are designed on the outer wall of the mounting circular plate 21, and these chutes are slidably connected with the rectangular column 4, making the movement of the rectangular column 4 on the mounting circular plate 21 smoother and avoiding the situation of asymmetric force or excessive friction. Through this sliding fit, the rectangular column 4 can be flexibly adjusted in multiple directions, thereby improving the adaptability of the entire installation structure and ensuring that various complex working conditions can be handled during installation; The limiting mechanism in the present invention is used to limit the nut 5 to prevent it from displacing or loosening during the rotation of the bolt 2. The design of the limiting structure enables the nut 5 to be in close contact with the inner wall of the cylindrical column 6, thus forming a firm fixing effect. The limiting mechanism avoids the loosening of the nut 5 caused by vibration or external force through precise design, which is crucial for ensuring the stability of the entire structural system. Through reasonable mechanical design, the limiting mechanism effectively reduces the accident risk caused by structural instability and improves the durability of the structure.

[0024] Such as Figures 1 to 10As shown in the figure, the limiting mechanism includes a driving component and a limiting component. There are four groups of driving components, and they are all designed to be evenly distributed in a circular pattern with the axis of the cylinder 6 as the center; the driving component includes an installation groove 61 opened on the outer wall of the cylinder 6. The installation groove 61 is rectangular in design. A slider 7 is slidably installed inside the installation groove 61. A clamping block 71 is fixedly installed on the top of the slider 7. A clamping groove 51 is opened on the outer wall of the nut 5. The clamping block 71 is clamped with the clamping groove 51; positioning grooves 73 are respectively opened on the outer walls on both sides of the slider 7. A positioning rod 62 is rotatably installed on the inner wall of the installation groove 61. The two ends of the positioning rod 62 are bent towards the corresponding positioning grooves 73 and are respectively slidably connected with the corresponding positioning grooves 73; the bottom of the slider 7 and the installation groove 61 are elastically connected by two springs 63. The two springs 63 are respectively located on both sides of the positioning rod 62; convex grooves 64 are provided on the inner walls on both sides of the installation groove 61. Convex blocks 72 are respectively fixedly installed on the outer walls on both sides of the slider 7. The two convex blocks 72 are respectively slidably connected with the corresponding convex grooves 64.

[0025] Adopting the above scheme: By setting four groups of driving components, and each group of components is evenly distributed in a circular pattern with the axis of the cylinder 6 as the center, the balance and stability of the limiting mechanism are ensured. This evenly distributed design makes the force on the overall mechanical structure more uniform, thus avoiding tilting or structural instability that may be caused by excessive unilateral force. Each driving component interacts with the slider 7 through its installation groove 61. The clamping block 71 on the slider 7 is clamped with the clamping groove 51 on the nut 5. Through this clamping method, an effective restriction on the nut 5 is formed. This clamping design ensures the stability of the nut 5 during operation and prevents loosening or displacement; In the limiting mechanism, the slider 7 is the main driving element. It realizes precise positioning and sliding through the cooperation of the positioning rod 62 and the positioning groove 73. The two ends of the positioning rod 62 are bent towards the corresponding positioning grooves 73 and are slidably connected, which can ensure the stable operation of the slider 7 in the installation groove 61 and accurately execute the required displacement. The bent design of the positioning rod 62 on both sides increases the stability of the slider 7, avoids the deviation or shaking of the slider 7, makes the positioning during the working process more accurate, and reduces the risk of failures caused by unstable structures; The elastic connection function of the spring 63 is crucial. The two springs 63 are located on both sides of the positioning rod 62 and are respectively connected to the inner wall of the slider 7 and the installation groove 61. This design can provide the necessary elastic support for the slider 7 to ensure that the slider 7 receives appropriate resilience during the sliding process; The sliding fit design between the convex block 72 and the convex groove 64 further enhances the stability and accuracy of the limiting mechanism. This matching structure can effectively guide the sliding of the slider 7 in the installation groove 61, avoid the abnormal displacement of the slider 7, reduce wear, maintain the smoothness of the sliding, and thus ensure the efficient operation of the entire limiting mechanism.

[0026] Working principle and usage process of the present invention: Construction workers first align the bolt 2 with the mounting hole 11, and then preliminarily fix the bolt 2 and the connecting piece 12 to the connecting frame 1 through the nut 5; To reinforce the connection between the bolt 2 and the connecting frame 1, the construction workers use tools to rotate the rotating column 3, and drive the three rotating blocks 31 to rotate together through the rotating column 3. Due to the arc design of the arc-shaped chute 311 on the outer wall of the rotating block 31, the rotational movement of the rotating block 31 is converted into a linear movement of the convex column 42 driving the rectangular column 4 along the rectangular chute 211. The rectangular column 4 drives the arc-shaped plate 41 to move together, so that the four arc-shaped plates 41 expand outwards, so that when the arc-shaped plate 41 is completely fitted with the mounting hole 11, the connection between the bolt 2 and the mounting hole 11 is strengthened; To prevent the nut 5 from rotating due to external force and causing the bolt 2 to loosen, the construction workers need to press the clamping block 71 forcefully, so that the positioning rod 62 slides on the inner wall of the positioning groove 73, so that the positioning rod 62 slides from the top of the positioning groove 73 to the bottom, and through the rebound of the spring 63, the slider 7 drives the clamping block 71 to move, and finally the clamping block 71 is clamped into the card slot 51 on the outer wall of the nut 5, so as to effectively limit the nut 5.
