The present invention provides the following embodiments.

[0026] Please refer to the attached Figure 1-4 The utility model provides a steel structure installation quick connection structure, including a fixing frame 2, a reinforcing plate 3 is fixedly connected to the top of the fixing frame 2, which is used to locally increase the thickness of the top of the fixing frame 2, so that the fixing frame 2 will not be deformed when subjected to the force of the rotation of the torsion block 6, a threaded hole is provided on the reinforcing plate 3 that passes through the top of the fixing frame 2, a threaded rod 5 is threadedly connected to the threaded hole, holes perpendicular to the fixing frame 2 are provided at both ends of the reinforcing plate 3, and the reinforcing plate 3 is fixed to the top of the fixing frame 2 by threaded fixing bolts 4; a torsion block 6 is welded to the top of the threaded rod 5, and the diameter of the torsion block 6 is larger than the diameter of the cross-section of the threaded rod 5, which is used to facilitate the rotation and twisting of the torsion block 6 welded on the top of the threaded rod 5, and the rotation of the threaded rod 5 drives the lifting block 7 to move vertically; an adjusting mechanism is provided in the fixing frame 2, and a fixed clamping mechanism is connected to the bottom of the adjusting mechanism.

[0027] The adjusting mechanism comprises a sliding block 8 and a lifting block 7. The two ends of the lifting block 7 are slidably connected to the sliding block 8. A sliding hole 71 matching with the threaded rod 5 is provided at the top of the lifting block 7. The top of the lifting block 7 is rotatably connected with the bottom of the threaded rod 5 through the sliding hole 71, and the threaded rod 5 rotates to drive the lifting block 7 to lift vertically, thereby adjusting the distance of the sliding block 8; a limiting block 72 is obliquely extended at both ends of the lifting block 7, one side of the sliding block 8 is set as an inclined surface, and a limiting groove 81 matching with the limiting block 72 is provided on the inclined side surface. The lifting block 7 and the sliding block 8 are slidably connected through the limiting block 72 and the limiting groove 81, and sliding bars 82 are welded on both sides of the sliding block 8; a fixing frame 2 is provided with a fixing frame 2 matching with the sliding block 8. The through slot 21 and the sliding slot 22 matched with the sliding bar 82, the through slot 21 passes through the bottom end of the fixing frame 2, and the sliding slot 22 is arranged on the inner wall of the through slot 21. Through the snap-fitting relationship between the through slot 21 and the sliding slot 22 and the adjusting mechanism, the position of the clamping mechanism can be quickly adjusted; the sliding block 8 is integrally slidably connected in the through slot 21, and is snap-fitted with the sliding bar 82 and the sliding slot 22 so that it can slide horizontally. Since the shape of the limit block 72 is set to be wide on the outside and narrow on the inside, and the shape of the limit slot 81 is set to be narrow on the outside and wide on the inside matched with the limit block 72, when the lifting block 7 moves downward, the limit blocks 72 at both ends squeeze the limit slot 81 so that the sliding block 8 moves horizontally to both ends synchronously.

[0028] The fixed clamping mechanism includes a receiving plate 9, a locking bolt 10, a G-shaped clamping block 11 and a movable rod 12. Two locking bolts 10 are threadedly connected to the lower surface of the receiving plate 9. The four locking bolts 10 all pass through the receiving plate 9 and are symmetrically connected to the threaded grooves opened at the bottom of the sliding block 8. The receiving plate 9 is threadedly fixed to the bottom of the sliding block 8, and the receiving plate 9 can move simultaneously when the lifting block 7 moves vertically and drives the sliding block 8 to move to both sides; the bottom of the receiving plate 9 is fixedly connected to a G-shaped clamping block 11, and extension plates are set at both ends of the clamping feet of the G-shaped clamping block. The extension plate is against the inner walls of the upper and lower ends of the steel body 1 to stabilize the steel body 1 and prevent it from being deflected by its own gravity. Three groups of symmetrical movable rods 12 are welded to the inner surface of the G-shaped clamping block 11. A movable hole 13 matching the movable rod 12 is opened through the connection of the steel body 1, and the length of the movable rod 12 is half the depth of the movable hole 13. When the movable rod 12 is clamped into the movable hole 13, it can be completely clamped inside the steel body 1, thereby increasing the stability of the connection. The fixed clamping mechanism and the sliding block 8 are both set to a symmetrical structure, and the fixed clamping mechanism and the connection of the steel body 1 are symmetrically distributed.

[0029] In the utility model, firstly, a movable hole 13 is pre-opened at the connection of the steel body 1 to be installed and connected, and then the torsion block 6 is rotated and twisted to drive the spiral rod 5 to move, and the spiral rod 5 drives the lifting block 7 to move downward. When the lifting block 7 moves downward, the limit blocks 72 at both ends squeeze the limit grooves 81 so that the sliding block 8 moves horizontally to both ends synchronously, and the sliding block 8 drives the clamping mechanism fixedly connected by the locking bolts 10 to adjust the symmetrical G-shaped clamping block 11 to the maximum distance. At this time, the installation structure is placed just above the connection of the steel body 1 with the hole opened, and the upper bottom end of the G-shaped clamping block 11 is clamped on the upper surface of the I-shaped steel body 1, and the center of the installation structure is aligned with the steel body 1. The center of the connection is rotated and twisted again to drive the spiral rod 5 to move upward, and the spiral rod 5 drives the lifting block 7 to move upward. The limit blocks 72 at both ends drag the limit grooves 81 to make the sliding block 8 move horizontally inward synchronously, and the clamping mechanism moves inward at the same time as the sliding block 8. Since extension plates are set at both ends of the clamping feet of the G-shaped clamping block 11, and the extension plates at both ends are against the inner walls of the upper and lower ends of the steel body 1, the steel body 1 will not be offset during the movement of the clamping mechanism. When the three groups of movable rods 12 welded on the symmetrical G-shaped clamping block 11 are all clamped in the movable holes 13 at the connection of the steel body 1, stop twisting the twisting block 6 to complete the installation and connection of the steel body 1.
