[0002] Municipal roads refer to roads that reach various areas of the city and are used for transportation and pedestrians within the city. They are convenient for residents' lives, work, cultural and entertainment activities, and are connected to roads outside the city to carry external traffic. During road construction, dust nets are usually set up at the construction site to reduce the spread of dust from the construction site.

[0003] After searching, the patent number is CN218293130U, which discloses a municipal road construction dust reduction fence with an easy-to-adjust range. Although it has the function of independent disassembly, the enclosure range can be quickly changed, it has a directional water sprinkling function, can perform multi-directional water sprinkling and dust removal functions, and has a detachable and washable dust net, but when in use, the coverage area of ​​the dust net cannot be arbitrarily increased during use. When strong winds sweep and cause excessive dust, it will affect the dust prevention effect.

[0004] For this reason, a dust-proof net which is easy to disassemble for road construction is proposed. Utility Model Content

At this time, the movable ring can slide upward along the threaded screw through the threaded hole, so that the connecting frame can slide upward along the movable hole at the top of the base through the limit rod during the sliding of the movable ring. At this time, the connecting frame can drive the dustproof net main body to slide upward, which can increase the coverage area of ​​the dustproof net main body and the dustproof effect of the dustproof net main body. The user rotates the first turntable counterclockwise to make the dustproof net main body at the bottom of the connecting frame slide downward. The adjustment method is simple, which is convenient for users to adjust according to actual needs and can improve the use experience.

[0016] 2. By setting a winding component, when the user drives the connecting frame to slide upward, the dust-proof net main body in the storage tube can be unfolded on the winding roller, which is convenient for the user to increase the coverage area of ​​the dust-proof net main body. When the connecting frame is reset, the bottom end of the dust-proof net main body is in a loose state. At this time, the second turntable is rotated clockwise, and the second turntable can drive the winding roller to rotate in the storage tube. At this time, the winding roller can wind up the loose dust-proof net main body, which can make the dust-proof net main body in a taut state, thereby ensuring the dust-proof effect and facilitating the retraction and release of the dust-proof net main body.
