Therefore, the directional words used are used to illustrate rather than limit the invention.

[0024] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0025] According to the embodiment of the utility model, a green construction dustproof net is provided. Figures 1 to 4 , including a fixed frame 2 and columns 1 located on both sides of the fixed frame 2, a first net body 3 is fixedly arranged in the fixed frame 2, the first net body 3 can shield the dust at the construction site, a limiting plate 5 and a receiving groove 4 for receiving the fixed frame 2 are provided on the column 1, and the limiting plate 5 can slide in a direction close to or away from the fixed frame 2 to press against or detach from the fixed frame 2.

[0026] It should be noted that when installing the fixed frame 2, the fixed frame 2 is placed in the receiving groove 4, and the limiting plate 5 is slid toward the fixed frame 2, so that the plate surface of the limiting plate 5 is pressed against the fixed frame 2, thereby fixing the fixed frame 2 in the receiving groove 4; when removing the fixed frame 2, the limiting plate 5 is slid in the opposite direction to separate the limiting plate 5 from the fixed frame 2, thereby taking the fixed frame 2 out of the receiving groove 4. The installation and removal of the fixed frame 2 are realized by the cooperation between the limiting plate 5 and the receiving groove 4, and then the installation and removal of the first mesh body 3 are realized, without the aid of other tools, and the operation is simple; at the same time, the two columns 1 are connected only through the fixed frame 2, that is, the distance between the two columns 1 is adjustable, and can be combined with a variety of fixed frames 2 of different lengths to meet the actual needs of the construction site.

[0027] Specifically, universal wheels 12 are fixedly arranged at the bottom of the two columns 1 through connecting plates 11, and the connecting plates 11 are fixedly connected to the columns to facilitate the movement of the green construction dust-proof net as a whole and reduce the carrying intensity.

[0028] In the green construction dust-proof net of the present embodiment, grooves are cut on the opposite side walls of the two columns 1 to form a receiving groove 4. The first groove wall of the receiving groove 4 is located on the opposite side of the two receiving grooves 4. A slide groove 6 is opened on the first groove wall to improve the compactness of the structure. The limit plate 5 slides in the slide groove 6 in the direction approaching or away from the fixed frame 2. When the limit plate 5 completely enters the slide groove 6, the fixed frame 2 can be placed in the receiving groove 4 or taken out from the receiving groove 4.

[0029] In the green construction dust-proof net of the present embodiment, a guide hole 8 connected to the slide groove 6 is provided on the column 1, and an adjustment component 7 for controlling the sliding of the limit plate 5 is arranged inside the guide hole 8. The adjustment component 7 includes a shift block 71 and a spring 72. The shift block 71 is fixedly connected to the limit plate 5, and the two ends of the spring 72 are respectively fixedly connected to the inner wall of the guide hole 8 and the shift block 71.

[0030] It should be noted that the spring 72 is always in a compressed state, and the elastic force of the spring 72 can ensure that the limit plate 5 is always pressed against the fixed frame 2 during the use of the green construction dustproof net, preventing the fixed frame 2 from falling off from the receiving groove 4. The limit plate 5 can slide by moving the shift block 71, and at the same time, the guide hole 8 can limit the shift block 71 to prevent the limit plate 5 from falling off from the slide groove 6.

[0031] In the green construction dustproof net of the present embodiment, the adjustment component 7 also includes a guide rod 73, a spring 72 is sleeved on the outside of the guide rod 73, one end of the guide rod 73 passes through the shift block 71 and is slidably connected to the shift block 71, and the other end is fixedly connected to the inner wall of the guide hole 8, and the guide rod 73 guides the movement of the shift block 71.

[0032] In the green construction dustproof net of this embodiment, a limit block 9 is fixedly provided on the second groove wall of the accommodating groove 4, and a through hole 10 matching the limit block 9 is opened on the fixing frame 2. When the fixing frame 2 is installed, the limit block 9 passes through the through hole 10.

[0033] It should be noted that, after the limiting block 9 passes through the through hole 10 , it can limit the degree of freedom of the fixing frame 2 in the vertical direction, thereby further limiting the fixing frame 2 .

[0034] Optionally, the limiting block 9 is a rod with a threaded end. After the limiting block 9 is installed in the receiving groove 4 , a nut can be screwed onto the rod to limit the fixing frame 2 .

[0035] The green construction dustproof net of this embodiment also includes a second net body 13, which is located below the fixed frame 2 to shield the area between the fixed frame 2 and the ground to prevent dust from escaping from below the fixed frame 2, thereby improving the dustproof effect of the entire green construction dustproof net.

[0036] It should be noted that the second mesh body 13 can be rotated relative to the fixed frame 2. When the green construction dust-proof net is needed to play a dust-proof role, the second mesh body 13 is rotated to the bottom of the fixed frame 2 and parallel to the first mesh body 3. When the green construction dust-proof net is pushed as a whole, the second mesh body 13 can be rotated to form a certain angle with the first mesh body 3 to prevent the uneven ground at the construction site from causing damage to the second mesh body 13, thereby increasing the service life of the green construction dust-proof net.

[0037] In the green construction dust-proof net of the present embodiment, a connecting rod 14 is provided on the second net body 13, a connecting block 15 is provided at the bottom of the fixed frame 2, and a rotating groove 151 matching the connecting rod 14 is opened on the connecting block 15. The connecting rod 14 passes through the rotating groove 151 and can rotate relative to the connecting block 15. Specifically, a plurality of connecting blocks 15 are provided to ensure the connection stability of the connecting rod 14, and the rotating groove 151 is in an open state to facilitate the disassembly and assembly of the connecting rod 14.

[0038] When in use, push the green construction dustproof net to the position where dust protection is required on the construction site, rotate the second net body 13 to the bottom of the fixed frame 2, the second net body 13 blocks the area between the fixed frame 2 and the ground, and the first net body 3 blocks the construction position. When the first net body 3 is damaged and needs to be replaced, the shift block 71 is moved, and the shift block 71 drives the limit plate 5 to slide into the inside of the slide groove 6. At the same time, the spring 72 is compressed and deformed. After the limit plate 5 completely slides into the inside of the slide groove 6, the limit of the limit plate 5 on the fixed frame 2 can be released, and then the damaged first net body 3 together with the fixed frame 2 can be removed from the accommodating groove 4, and the new first net body 3 together with the fixed frame 2 can be installed in the accommodating groove 4, and the limit block 9 is passed through the through hole 10, and then the shift block 71 is released, and the restoring force of the spring 72 is used to push the limit plate 5 to slide out of the slide groove 6, thereby pressing against the fixed frame 2 to complete the replacement of the first net body 3; when the second net body 13 is damaged and needs to be replaced, the connecting rod 14 is directly removed from the rotating groove 151, so as to remove the damaged second net body 13, and then the connecting rod 14 of the new second net body 13 is installed in the rotating groove 151, and the replacement of the second net body 13 can be completed.

[0039] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
