[0021] Working principle:

[0022] When disassembling and assembling the construction site protection net in this structure, first remove the fixing bolts 4 from the outer side of the mounting plate 2 to separate the top of the mounting plate 2 and the rectangular grid frame 1, then stretch the L-shaped pressing plate 10 upward at the longitudinal slide groove 8 through the slider 9, rotate and pull the locking plates 12 at the ends of the L-shaped pressing plates 10 on the left and right sides, and disengage the top rod 7 at the top end of the longitudinal round rod 5 from the locking plate 12, and then release the locking plate 12, and its locking plate 12 is reset under the spring action of the reset spring shaft 11, at this time, the longitudinal round rod 5 and the protective filter screen 6 fall to the hollow groove inside the rectangular grid frame 1 under the action of gravity, and then the mounting plate 2 is rotated through the hinge shaft 3, that is, the left and right sides of the rectangular grid frame 1 and the mounting plate 2 are separated, at this time, the L-shaped pressing plate 10 is pulled outward from the top of the rectangular grid frame 1, and the longitudinal round rod 5 and the protective filter screen 6 are pulled out from the hollow groove inside the rectangular grid frame 1, thereby completing the removal process of the protective filter screen 6 from the rectangular grid frame 1;

[0023] Similarly, when the protective filter 6 needs to be installed, the protective filter 6 needs to be firstly wound on the left and right two longitudinal round rods 5, and then the two longitudinal round rods 5 are inserted into the hollow groove inside the rectangular grid 1, and the bottom end of the longitudinal round rod 5 is inserted into the circular groove of the bottom plate of the rectangular grid 1, as shown in FIG. Figure 3 As shown, the mounting plate 2 is then rotated, and the L-shaped pressure plate 10 is slid, and the locking plate 12 is pulled, so that the locking plate 12 limits and clamps the top rod 7 at the top end of the longitudinal round rod 5. At this time, the L-shaped pressure plate 10 presses the longitudinal round rod 5, and under the action of gravity or manually, the L-shaped pressure plate 10 is pulled downward to press the longitudinal round rod 5, and then the fixing bolts 4 are used to fix the top side of the mounting plate 2 and the side of the rectangular grid 1, thereby completing the assembly effect of the building protection net, and the assembled protection net is a double-layer filter screen structure, which effectively prevents dust from spreading, and the overall structure is convenient for loading and unloading, and is convenient for disassembly and cleaning of the protection net, which is suitable for daily use on construction sites.
