[0002] The dust-proof net is a wind-proof and dust-suppressing net used in construction sites or open-air material yards. The dust-proof net uses the principles of aerodynamics and is processed into a wind-proof and dust-suppressing wall with a certain geometric shape, opening rate and different hole shape combination according to the results of on-site environmental wind tunnel experiments. When the circulating air passes through the wall from the outside, an upward and downward interfering airflow is formed on the inside of the wall to achieve the effect of strong wind on the outside, weak wind on the inside, small wind on the outside, and no wind on the inside, thereby preventing dust from flying.

[0003] For example, a Chinese patent discloses: a dust screen with a fixing device, patent number: CN217419574U, which increases the tightness of the connection between the pressure plate 1 and the pressure plate 2 through the design of the plug-in slot 1, the plug-in slot 2 and the card plate, and prevents the dust screen from slipping out from between the pressure plate 1 and the pressure plate 2.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: when installing the dust net of the above device, short plate one and short plate two need to be aligned and plugged into slot one and slot two respectively. In order to ensure accurate alignment of the assembly, additional effort and time are required, and higher operating skills and accuracy are required, which increases the complexity of the installation and causes inconvenience in assembly.

In order to ensure accurate assembly alignment, extra effort and time are required, higher operating skills and accuracy are required, which increases the complexity of installation and causes inconvenience in assembly. The dustproof net body is passed through the slide slot into the main body of the sliding device, and the rotating rod is driven to rotate by turning the handle, and the rotating rod drives the two-way threaded rod to rotate. During the rotation of the two-way threaded rod, the two rectangular blocks are driven to slide, and during the sliding of the rectangular blocks, the pressure plate is driven to slide by the connecting rod. During the sliding of the pressure plate, its sliding position is limited by the limit block to ensure the stability of the sliding extrusion of the pressure plate. The pressure plate can be driven to slide by turning the handle to extrude and assemble the dustproof net body, thereby improving the convenience of assembly.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem that when installing the dust net of the above-mentioned device, the short plate one and the short plate two need to be aligned and plugged into the positions of the slot one and the plugging slot two respectively. In order to ensure accurate assembly alignment, extra effort and time are required, higher operating skills and accuracy are required, the complexity of installation is increased, and the technical problem of inconvenient assembly is caused. The overall idea is as follows: it includes a device main body 11, a slide groove 12 is opened inside the device main body 11, and a dust net body 13 is sleeved inside the slide groove 12. Two connecting seats 14 are fixedly connected at both ends of the device main body 11, and sharp spikes 15 are slidably connected inside the two groups of connecting seats 14. The dust net body 13 is covered on the soil pile to prevent the soil from being blown away by the wind or washed away by rainwater, thereby protecting the soil pile. The spiked nails 15 are knocked and buried in the soil, the device main body 11 is fixed, and the dust net body 13 is slid into the device main body 11 through the slide groove 12.

[0027] The device body 11 is internally rotatably connected with a rotating rod 16, one side of which is fixedly connected with a handle 17, the outer surface of the rotating rod 16 is sleeved with a limiting mechanism, the limiting mechanism includes a bidirectional threaded rod 18, the bidirectional threaded rod 18 is sleeved on the outer surface of the rotating rod 16, the outer surface of the bidirectional threaded rod 18 is threadedly connected with two rectangular blocks 19, the outer surfaces of the two rectangular blocks 19 are both rotatably connected with connecting rods 21, the two connecting rods 21 are internally rotatably connected with a pressing plate 22, the device body 11 is internally fixedly connected with a limiting block 23, the rotating rod 16 is rotatably connected to the limiting block 23 Internally, the pressure plate 22 is slidably connected to the outer surface of the limit block 23, and the rotating handle 17 drives the rotating rod 16 to rotate, and the rotating rod 16 drives the bidirectional threaded rod 18 to rotate. During the rotation of the bidirectional threaded rod 18, the two rectangular blocks 19 are driven to slide. During the sliding of the rectangular blocks 19, the pressure plate 22 is driven to slide through the connecting rod 21. During the sliding of the pressure plate 22, its sliding position is limited by the limit block 23 to ensure the stability of the sliding extrusion of the pressure plate 22. By screwing the handle 17, the pressure plate 22 can be driven to slide to extrude and assemble the dustproof net body 13, thereby improving the convenience of assembly.

[0028] A ratchet 24 is sleeved on the outer surface of the rotating rod 16, and a support block 25 is fixedly connected to the inside of the device body 11.

A tension spring 27 is sleeved on the outer surface of the support block 25, and the tension spring 27 is sleeved on the outer surface of the pawl 26. During the rotation of the rotating rod 16, the ratchet 24 is driven to rotate, and the ratchet 24 is restricted from reversing by the rotation of the pawl 26, thereby ensuring the stability of the rotating rod 16 after extrusion and assembly, and preventing the rotating rod 16 from reversing and loosening after the dustproof net body 13 is assembled, which is beneficial to improving the safety and stability of the use of the dustproof net body 13. During the rotation of the pawl 26, it is pulled to reset by the tension spring 27.

[0029] In view of the problems existing in the prior art, the utility model provides a dustproof net that is easy to assemble. The dustproof net body 13 is inserted into the sliding device body 11 through the slide groove 12, and the handle 17 is screwed to drive the rotating rod 16 to rotate. The rotating rod 16 drives the bidirectional threaded rod 18 to rotate. During the rotation of the bidirectional threaded rod 18, the two rectangular blocks 19 are driven to slide. During the sliding of the rectangular blocks 19, the connecting rod 21 drives the pressure plate 22 to slide.

By screwing the handle 17, the pressure plate 22 can be driven to slide to extrude and assemble the dustproof net body 13, thereby improving the convenience of assembly.

[0030] Working principle:

[0031] The first step is to cover the dust-proof net body 13 on the soil pile to prevent the soil from being blown away by the wind or washed away by rain, thereby protecting the soil pile; the spiked nails 15 are knocked and buried in the soil to fix the device body 11; the dust-proof net body 13 is slid into the device body 11 through the slide groove 12; the handle 17 is screwed to drive the rotating rod 16 to rotate; the rotating rod 16 drives the bidirectional threaded rod 18 to rotate; the bidirectional threaded rod 18 drives the two rectangular blocks 19 to slide during the rotation; the rectangular blocks 19 slide during the sliding process, and the pressing plate 22 is driven to slide through the connecting rod 21; the sliding position of the pressing plate 22 is limited by the limit block 23 during the sliding process, thereby ensuring the stability of the sliding extrusion of the pressing plate 22; the pressing plate 22 can be driven to slide by screwing the handle 17 to extrude and assemble the dust-proof net body 13, thereby improving the convenience of assembly.

[0032] In the second step, the rotating rod 16 drives the ratchet 24 to rotate during the rotation, and the ratchet 24 is restricted from reversing by the rotation of the pawl 26, thereby ensuring the stability of the rotating rod 16 after extrusion assembly, and avoiding the loosening of the rotating rod 16 after the dustproof net body 13 is assembled, which is beneficial to improving the safety and stability of the use of the dustproof net body 13. The pawl 26 is reset by pulling the tension spring 27 during the rotation.
