The connecting component 5 includes a guide bar 51, a hinge 52, a fixing block 53 and a fastening screw 54, and the side of the guide bar 51 is installed with a hinge 52 by bolts. There are two guide bars 51, and the two guide bars 51 are respectively installed on the two sides of the hinge 52 by bolts. The two guide bars 51 form a rotating structure through the hinge 52. The guide bar 51 is set as a rotating structure, so that the guide bar 51 is convenient for the staff to fold, store and unfold, and the outer side of the guide bar 51 is symmetrically installed with fixing blocks 53 front and back. There are two groups of fixing blocks 53, and the two groups of fixing blocks 53 are respectively installed on the sides of the guide bar 51 and the main load-bearing frame 1. The installation positions of the two groups of fixing blocks 53 correspond one to one, and the internal threads of the fixing blocks 53 are connected with fastening screws 54.

[0023] like Figure 1-Figure 3As shown, a stretchable grid 2 is fitted on the right side of the main load-bearing frame 1, and a counterweight assembly 4 is movably installed on the right side of the stretchable grid 2, a connecting assembly 5 is fitted on the left side of the main load-bearing frame 1, and a clamping assembly 6 is slidably connected to the inner surface of the connecting assembly 5, and the clamping assembly 6 includes a T-shaped slider 61, a metal load-bearing block 62, a strong magnet 63 and a limiting groove 64, and a metal load-bearing block 62 is fixedly installed on the side of the T-shaped slider 61, and a strong magnet 63 is fitted on the other side of the metal load-bearing block 62, and a limiting groove 64 is provided on the side of the T-shaped slider 61, and the internal size of the limiting groove 64 is similar to the limiting bolt. 7 completely matches the external dimensions of the guide bar 51, and the limit bolt 7 forms a snap-fit ​​structure with the T-shaped slider 61 through the limit groove 64.

[0024] In summary, the combined assembled grid is first based on Figures 1 to 3 In the structure shown in the figure, the staff unfolds the stretchable grid 2 and fits it on the right side of the main load-bearing frame 1. Then the staff completes the installation of the counterweight assembly 4 by respectively engaging the first hook 43 and the second hook 44 into the metal connecting ring 3 at the corresponding position. Then the staff takes out the connecting assembly 5, and then opens the guide bar 51 by rotating the hinge 52. Then the staff aligns the fixing block 53 on the side of the guide bar 51 with the fixing block 53 on the side of the main load-bearing frame 1, and then rotates the fastening screw 54 to complete the fitting installation between the guide bar 51 and the main load-bearing frame 1. Then the staff fits a corner of the advertising cloth on the outer surface of the metal load-bearing block 62. Then, a strong magnet 63 is placed on the outer surface of the advertising cloth. At this time, the strong suction between the strong magnet 63 and the metal supporting block 62 is used to clamp and fix the corners of the advertising cloth. Similarly, the other three corners of the advertising cloth are installed on the other three groups of clamping components 6. Then the staff grabs the metal supporting block 62 and drives the T-shaped slider 61 to slide up and down on the inner surface of the guide strip 51. When the metal supporting block 62 moves to the specified position, the staff grabs the limit bolt 7 and passes it through the guide strip 51 and inserts it into the limit groove 64 to complete the locking work of the T-shaped slider 61. When the four groups of clamping components 6 are fixed, the advertising cloth is automatically unfolded to complete the overall installation of the grid.
