[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 - Figure 3 As shown, in this embodiment, in order to facilitate the assembly and disassembly of the dustproof net body 1 on the scaffold 2 through the installation mechanism 3, the specific use principle of the installation mechanism 3 in conjunction with the dustproof net body 1 is as follows:

[0020] First, the movable plate 8 is manually pulled by the handle 12 installed on the front end wall of the movable plate 8, and the connecting rods 9 installed on the left and right sides of the rear end wall of the movable plate 8 will move forward in the connecting holes 6 opened on the left and right sides of the front end wall of the bottom plate 5 installed at the bottom end of the cross bar 4, and force the tension spring 10 which is set outside the connecting rod 9 and installed between the bottom plate 5 and the movable plate 8 to be forced to perform a stretching operation until the limiting rod 11 installed on the rear end wall of the movable plate 8 moves out of the limiting groove 7 opened on the front end wall of the bottom plate 5, and then, the upper part of the dustproof net body 1 is placed between the bottom plate 5 and the movable plate 8, and then, the pulling force on the movable plate 8 is released. At this time, the tension spring 10 will perform a recovery extension operation and drive the movable plate 8 to move backward to close the The dust-proof net body 1 is close to the bottom plate 5, and the limiting rod 11 on the rear end wall of the movable plate 8 passes through the mesh hole of the upper part of the dust-proof net body 1 and is inserted into the limiting groove 7. In this way, the mounting mechanism 3 can be pre-installed and fixed on the upper and lower ends of the dust-proof net body 1. When the dust-proof net body 1 needs to be installed on the scaffolding 2 for use to protect the dust-proof environment for construction, the cross bar 4 above the dust-proof net body 1 is horizontally placed between the vertically symmetrical pipe racks on the scaffolding 2, and the pipe racks on the scaffolding 2 are placed between the arc-shaped clamping plates 21 symmetrical on the left and right sides of the rear end of the cross bar 4. Then, the knob 18 is manually rotated to drive the rotating rods 17 installed at both ends of the bidirectional screw 16 through the knob 18 to the symmetrical fixing blocks 1 installed on both sides of the front end wall of the cross bar 4. 3, and the rotating rod 17 will drive the bidirectional screw 16 to rotate. During the rotation, because the symmetrical adjusting plates 19 are respectively threadedly connected with the bidirectional screw 16 through the screw holes 20 opened on the side walls, the symmetrical adjusting plates 19 will pass through the screw holes 20 along the bidirectional screw 16 in the transverse opening 15 opened between the front end wall fixing blocks 13 of the cross bar 4 to make a relative movement operation. At this time, the arc clamping plate 21 installed at the rear end of the adjusting plate 19 will also make a relative movement operation until the pipe rack on the scaffolding 2 is clamped and fixed between the arc clamping plates 21. Finally, the cross bar 4 below the dustproof net body 1 is pulled to straighten the dustproof net body 1, and then the lower end of the dustproof net body 1 is aligned with the scaffolding in the same way. The frame 2 can be connected and fixed, so that the dustproof net body 1 can be quickly installed and fixed on the scaffolding 2 for use. When the dustproof net body 1 is disassembled after the construction is completed, it is only necessary to rotate the knob 18 in the opposite direction to make the arc-shaped clamping plate 21 move in the opposite direction and no longer clamp the pipe rack on the scaffolding 2, so that the dustproof net body 1 can be disassembled, and the cross bar 4 can be rotated to reel up the dustproof net body 1. At the same time, after the dustproof net body 1 is damaged, the handle 12 is pulled to move the limit rod 11 out of the mesh of the dustproof net body 1, and the dustproof net body 1 is pulled out from between the bottom plate 5 and the movable plate 8, and the dustproof net body 1 can be replaced, thereby achieving the purpose of facilitating the disassembly, use and replacement of the dustproof net body 1 on the scaffolding 2.
