DETAILED DESCRIPTION

[0020] like Figure 1-Figure 5 As shown, a steel structure anti-loosening support assembly includes a vertically arranged column 1 and a crossbeam 2, wherein the column is provided with a limit slot 3, and the crossbeam 2 is clamped in the limit slot 3.

[0021] A support rod 4 is obliquely arranged between the column 1 and the beam 2. Specifically, a first connecting ear 5 is fixedly arranged on the column 1, and a second connecting ear 6 is fixedly arranged on the beam 2. Both ends of the support rod 4 are fixedly connected to the first connecting ear and the second connecting ear respectively.

[0022] Both ends of the support rod 4 are respectively provided with connecting bolts 7 for connecting it with the column 1 and the crossbeam 2, and the free end of the connecting bolt 7 is provided with an anti-loosening nut 8 adapted thereto. Two first sliding grooves 9 are symmetrically provided in the middle of the anti-loosening nut 8 along its radial direction, and a second sliding groove 10 connected thereto is provided between each of the first sliding grooves 9 and the outer end surface of the anti-loosening nut 8, and the width of the second sliding groove 10 is smaller than the width of the first sliding groove 9. An anti-loosening block 11 is slidably installed in the first sliding groove 9, and a spring 12 is connected between the anti-loosening block 11 and the inner end of the first sliding groove 9. A shift rod 13 is slidably provided in the second sliding groove 10, one end of the shift rod 13 is fixedly connected to the anti-loosening block 11, and the other end of the shift rod 13 extends to the outside of the second sliding groove 10.

[0023] During installation of the present invention, the connecting bolt 7 is passed through the through holes corresponding to the ends of the support rod 4 and the first connecting ear 5 or the second connecting ear 6, and then the anti-loosening nut 8 is tightened and installed. The connecting bolt 7 is provided with an anti-loosening ring groove 14 corresponding to the anti-loosening block 11. When the anti-loosening nut 8 is screwed, the staff member pushes the two push rods 13 outward, thereby causing the two anti-loosening blocks 11 to retract into the corresponding first chute 9, so as to facilitate screwing the anti-loosening nut 8 until it is tightened. When the anti-loosening nut 8 is in the tightened state, the two anti-loosening blocks 11 face the anti-loosening ring groove 14. Under the action of the restoring elastic force of the spring 12, the two anti-loosening blocks 11 move toward the outside of the first chute 9 until the ends match the anti-loosening ring groove 14, which can effectively prevent the anti-loosening nut from loosening outward, thereby ensuring the connection strength between the support rod and the column and the crossbeam.

[0024] As a further improvement to the present invention, each second chute 10 is provided with a lever-limiting mechanism. This mechanism comprises a limiting groove 15 perpendicular to and formed at each end of the second chute 10, and a limiting member 16 with a T-shaped cross-section that plugs into and engages with the limiting groove 15 and the second chute 10. The end of the limiting member 16 that engages with the limiting groove 15 extends outside the limiting groove 15. Furthermore, threaded holes of identical specifications and axes are defined on the outer wall of the anti-loosening nut 8 and on the limiting member. A matching fastening screw 17 is installed in both of these threaded holes. In actual use, before screwing the anti-loosening nut 8, the lever 13 is moved to push the anti-loosening block 11 into the first chute 9, and then each of the limiting members 16 is inserted into the corresponding limiting groove 15 and the second chute 10 near the inner wall of the anti-loosening nut 8. The lever 13 is fixed and limited by the limiting member 16 to prevent the lever 13 and the anti-loosening block 11 from sliding toward the center hole of the anti-loosening nut 8 and affecting the normal screwing of the anti-loosening nut 8 during the process of screwing the anti-loosening nut 8 on the connecting bolt 13. When the anti-loosening nut 8 is tightened, the limiting member 16 can be pulled out, and under the action of the restoring elastic force of the spring 12, the two anti-loosening blocks 11 move toward the outside of the first chute 9 until the ends are matched with the anti-loosening ring groove 14. Then insert the limiting member 16 into the limiting groove 15 and the second sliding groove 10 near one end of the outer peripheral wall of the anti-loosening nut 8, and screw in the fastening screw 17 to fix the limiting member 16, so that the limiting member 16 presses the lever 13 and the anti-loosening block 11 in the direction of the anti-loosening ring groove 14.

[0025] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
