Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3 , an embodiment of the utility model is provided: a portal steel frame reinforcement structure, including a horizontal frame 1 and a vertical frame 2, a fixed box 3 is arranged between the horizontal frame 1 and the vertical frame 2, a knob 4 is rotatably connected inside the fixed box 3, a bevel gear 1 5 is fixedly connected to the lower surface of the knob 4, a limiting assembly 6 is arranged on the outer wall of the fixed box 3, a transmission rod 7 is rotatably connected inside the fixed box 3, a screw rod 8 is fixedly connected to one end of the transmission rod 7, a bevel gear 2 9 is fixedly connected to the other end of the transmission rod 7, the bevel gear 2 9 is meshed with the bevel gear 1 5, a connecting tube 10 is threadedly connected to the outer wall of the screw rod 8, and a hinge block 11 is fixedly connected to one side of the outer wall of the connecting tube 10; the limiting assembly 6 includes a limiting rod 601, one end of the limiting rod 601 is fixedly connected to one side of the outer wall of the fixed box 3, the outer wall of the limiting rod 601 is slidably connected to the limiting block 602, and the lower surface of the limiting block 602 is fixedly connected to the upper surface of the connecting tube 10;

[0024] Specifically, first, the angle is precisely adjusted by rotating the hinge block 11; next, the knob 4 is turned to drive the bevel gear 1 5 to mesh and rotate with the bevel gear 2 9; then, the power of the bevel gear 2 9 is transmitted to the connecting cylinder 10, causing it to rotate; the connecting cylinder 10 is one of the key components in the present design, and its rotation is directly related to the tensioning degree of the reinforcement material; in this way, the user can adjust the position of the connecting cylinder 10 in real time to achieve the ideal tensioning effect; the limit block 602 is located on the upper surface of the connecting cylinder 10 and can slide on the outer wall of the limit rod 601; in this way, the flexibility of operation is guaranteed, the stability of the system is increased, and the potential risks caused by over-adjustment are prevented.

[0025] Refer to the figure Figure 2 and Figure 4 , the outer wall of the hinge block 11 is rotatably connected with the hinge seat 12, and one side of the outer wall of the hinge seat 12 is fixedly connected with a connecting plate 13; the connecting plate 13 is internally slidably connected with a limiting plate 15, and one side of the outer wall of the limiting plate 15 is fixedly connected with a connecting frame 14; one side of the outer wall of the connecting frame 14 is fixedly connected with a sliding block 16, and the outer wall of the sliding block 16 is slidably connected with a connecting frame 2 17; the inner thread of the connecting frame 2 17 is connected with a fastening bolt 18, and the fastening bolt 18 is rotatably connected to the inner wall of the sliding block 16; one side of the outer wall of the connecting frame 2 17 is fixedly connected with a limiting plate 2 19, and the outer wall of the limiting plate 2 19 is slidably connected with a connecting plate 2 20; the inner thread of the connecting plate 20 is connected with a fastening bolt 21, and the fastening bolt 21 is rotatably connected to the outer wall of the limiting plate 2 19;

[0026] Specifically, when adjusting the steel frame structure, it is first necessary to pull the connection frame 14 so as to make precise adjustments according to the width of the steel frame; after the adjustment is completed, the connection frame 14 needs to be closely fitted to the outer walls of the horizontal frame 1 and the vertical frame 2; after the connection frame 14 is adjusted, we need to pull the connection frame 2 17 so that the limit plate 2 19 is adjusted accordingly on the inner wall of the connection plate 2 20 according to the sliding of the connection frame 14; this step is to ensure that the steel frame can be evenly distributed when subjected to stress to avoid structural damage due to stress concentration; after the adjustment is completed, the fastening bolts 21 need to be screwed into the connection plate 2 20 inside, so that it contacts the outer wall of the limit plate 2 19, thereby further improving the stability of the steel frame; after the fastening bolt 21 is installed, the connecting frame 2 17 needs to be inserted into the outer wall of the sliding block 16; this step is to enable the steel frame to be fine-tuned in the horizontal direction to adapt to different working environments; after the connecting frame 2 17 is inserted into the sliding block 16, the fastening bolt 18 needs to be twisted into the sliding block 16 and the connecting frame 2 17 inside, so as to achieve the purpose of adjusting according to the width of the other side of the steel frame; this step can ensure that the steel frame is more evenly stressed and improve the stability and service life of the overall structure.

[0027] Working principle: When a reinforcement structure is needed, the connection frame 14 is pulled to adjust according to the width of the steel frame, and then the connection frame 14 is fitted to the outer walls of the horizontal frame 1 and the vertical frame 2. At this time, the connection frame 17 is pulled to make the limit plate 19 adjust on the inner wall of the connection plate 20 according to the sliding of the connection frame 14, and then the fastening bolt 21 is twisted into the inside of the connection plate 20 to contact the outer wall of the limit plate 19 for stabilization. At this time, the connection frame 17 is inserted into the outer wall of the sliding block 16, and the fastening bolt 18 is twisted into the inside of the sliding block 16 and the connection frame 17, so as to achieve the effect of further adjusting according to the width of the other side of the steel frame;

[0028] Secondly, the hinge block 11 is rotated according to the installation angle, and then the knob 4 is rotated to drive the bevel gear 1 5 to mesh and rotate with the bevel gear 2 9, and then the bevel gear 2 9 drives the connecting tube 10 to rotate, thereby achieving the effect of facilitating the adjustment of the tensioning degree according to the reinforcement requirements, and the limit block 602 on the upper surface of the connecting tube 10 slides on the outer wall of the limit rod 601, thereby achieving the effect of facilitating the limiting.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
