DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 a steel structure support frame that can be adjusted, which includes a first support rod 1 and a second support rod 2. A docking groove 4 is provided inside the first support rod 1. A docking rod 3 inserted into the inside of the docking groove 4 is provided at the lower end of the second support rod 2. A plurality of card slots 8 are provided on one side of the docking rod 3. A fixing plate 5 located on one side of the first support rod 1 is provided at the top of the first support rod 1. A first screw rod 9 is provided on the fixing plate 5, and the first screw rod 9 is threadedly connected to the fixing plate 5. A limiting plate 6 is rotatably provided at one end of the first screw rod 9. Clamping blocks 7 cooperating with the card slots 8 are provided at both ends of the limiting plate 6. Fixing seats 10 are fixedly provided at both ends of the fixing plate 5. A cavity is provided inside the fixing seat 10. A spring is provided inside the cavity. A limiting rod 11 connecting both ends of the limiting plate 6 is provided at one end of the spring;

[0023] In this embodiment, through the cooperation of the clamping block 7 and the card slot 8, the docking rod 3 can be limited, so that the position of the second support rod 2 can be limited, and the stability of the first support rod 1 and the second support rod 2 during use can be improved;

[0024] When it is necessary to temporarily adjust the height of the vertical beam, rotate the first screw rod 9, and the position of the limiting plate 6 can be moved. At this time, the limiting rod 11 can compress the spring in the cavity, and then the clamping block 7 can be disengaged from the card slot 8. At this time, the docking rod 3 can be lifted and lowered in the docking groove 4. When the position of the docking rod 3 is adjusted, rotate the first screw rod 9. At this time, the compressed spring gradually returns to its original position, and then the clamping block 7 can re-enter the card slot 8, which is convenient for temporarily adjusting the height of the vertical beam, and thus convenient for temporarily adjusting the height of the steel structure support frame, and the limitation during use is low.

[0025] In this embodiment, the cross-section of the docking groove 4 is cross-shaped, which can improve the stability of the docking rod 3 during telescoping.

[0026] In this embodiment, two support rods 12 are symmetrically arranged on both sides of the fixing plate 5, one end of the support rod 12 is provided with a positioning seat 13 that slides with the first support rod 1, a plurality of slide grooves 14 are symmetrically arranged on the top of the first support rod 1, and a slider that slides with the slide grooves 14 is arranged on the positioning seat 13, and a second screw rod 15 and a guide rod 17 are symmetrically arranged on the top of the first support rod 1, and the second screw rod 15 and the guide rod 17 respectively penetrate the two positioning seats 13, the second screw rod 15 is threadedly connected with the positioning seat 13, and the guide rod 17 slides with the positioning seat 13. The lower end of the second screw rod 15 is rotatably provided with a limit seat 16 fixed on the first support rod 1. The docking rod 3 and the first support rod 1 are equipped with scale bars. When the position of the docking rod 3 is fine-tuned, the block 7 cannot cooperate with the slot 8. At this time, the fixing plate 5 is first taken, and then the second screw rod 15 is rotated. Since the position of the second screw rod 15 is fixed, the two positioning seats 13 can slide along the second screw rod 15 and the guide rod 17 on both sides of the first support rod 1 through the effect of the threaded structure, thereby facilitating fine-tuning the positions of the fixing plate 5 and the limit plate 6, and enabling the block 7 to fully cooperate with the slot 8.

[0027] In this embodiment, the cross section of the slide groove 14 is T-shaped, and the cross section of the clamping groove 8 is trapezoidal.

[0028] In this embodiment, a toggle block is provided at the lower end of the second screw rod 15 and the outer end of the first screw rod 9 .
