It also includes a pair of stoppers 300, the two stoppers 300 are arranged oppositely, and the two mounting brackets 100 are respectively installed on the crossbeam 500 through the two stoppers 300. The limiting member 300 includes a base 310 and a mounting protrusion 320. The bottom of the base 310 is provided with a mounting protrusion 320 protruding from the base 310. The mounting protrusion 320 is integrally arranged at the bottom of the base 310. The mounting protrusion 320 is semi-cylindrical in shape, and an external thread is provided on the curved surface on the side of the mounting protrusion 320. When two limiting members 300 are spliced ​​together, the semi-cylindrical mounting protrusions 320 on the two limiting members 300 are butt-jointed to form a complete bolt column 410, and the bolt column 410 extends downward from the bottom surface of the base 310. The cross beam 500 is provided with a mounting hole, the bottom surface of the base 310 mounted on the cross beam 500 is against the top surface of the cross beam 500, the bolt column 410 passes through the mounting hole on the cross beam 500 and extends to the bottom of the cross beam 500, and a locking nut 420 threadedly connected to the bolt column 410 is sleeved on the bolt column 410, and the locking nut 420 is against the bottom surface of the cross beam 500 to achieve the fixing of the limiting member 300 on the cross beam 500.

[0045] like Figure 1 As shown, when two mounting brackets 100 are respectively mounted on two stoppers 300, an installation gap 130 is formed between the two frames 110. A waterproof plugging strip 600 for filling the installation gap 130 is inserted in the installation gap 130. The two sides of the waterproof plugging strip 600 are respectively against the side walls of the two frames 110 to prevent water from entering the installation gap 130, thereby sealing the gap at the joint of the two stoppers 300, with good waterproof effect, preventing the bolt column 410 and the locking nut 420 from being soaked in water and rusting, and extending the service life. Figure 3 As shown, the waterproof blocking strip 600 includes a waterproof portion 610 and a limiting portion 620.

The bottom surface of the limiting portion 620 abuts against the top surface of the frame 110 to cover the top of the gap between the waterproof portion 610 and the frame 110, thereby improving the waterproof effect of the waterproof blocking strip 600.

[0046] like Figure 2As shown, preferably, a limit buckle 314 extending upward into the installation gap 130 is provided on the top surface of the support section 3111, and limit slots 611 are respectively provided on the two side walls of the waterproof part 610 facing the frame 110.
