Before construction, the prefabricated frame is erected in front of the work surface, with the front end of the prefabricated frame touching the work surface. The adjustment mechanism is then used to adjust the width of the adjustment mechanism relative to the work surface and the length of the adjustment mechanism extension, and to adjust the bottom of the second protective cover 2 to abut against the work surface. The first protective cover 1 is then placed over the prefabricated frame, and the second protective cover 2 is placed over the first protective cover 1 and the adjustment mechanism. In this way, workers can work inside the first protective cover 1 and the second protective cover 2 to reduce dust stirring. Workers wear protective clothing and masks during work to reduce the impact of dust on themselves. The adjustment mechanism can be adjusted according to the actual situation of the work surface.
[0035] In some embodiments, the prefabricated frame includes: four base cylinders 3, which are rectangular in shape; each of the four base cylinders 3 has an adjusting cylinder 4 slidably connected to it; first through holes 5 and second through holes 6 are evenly arranged along the height direction of the base cylinders 3 and the adjusting cylinders 4; an adjusting member 7 is also provided between the base cylinders 3 and the adjusting cylinders 4; the base cylinders 3 and the adjusting cylinders 4 are connected to the first through holes 5 and the second through holes 6 through the adjusting member 7. Figure 1-5 As shown, the four base cylinders 3 of the prefabricated frame are rectangular in shape. The area they form can be a work area for one person, or it can be set according to the length of the work surface so that it can completely cover the work surface. The adjusting cylinder 4 inside the base cylinder 3 can slide, so that when the work area is disturbed in the height direction, the relative height of the adjusting cylinder 4 and the base cylinder 3 can be adjusted to suit the site environment. After the adjusting cylinder 4 and the base cylinder 3 are adjusted to the appropriate position, the adjusting component 7 passes through the first through hole 5 of the base cylinder 3 and the second through hole 6 of the adjusting cylinder 4 to connect them together. The adjusting component 7 can be a bolt and nut, or the adjusting component 7 itself can be a screw. The first through hole 5 of the adjusting cylinder 4 is provided with threads, so that the screw passes through the first through hole 5 and the second through hole 6. At the same time, the screw and the first through hole 5 are screwed together.
[0036] In some embodiments, each bottom cylinder 3 has a pair of first assembly parts 8 and second assembly parts 9 respectively disposed at its bottom and top, with the first assembly parts 8 and second assembly parts 9 of each bottom cylinder 3 facing the two adjacent bottom cylinders 3; the first assembly part 8 of each bottom cylinder 3 is connected to the second assembly part 9 of the adjacent bottom cylinder 3 by a connecting mechanism; each adjusting cylinder 4 has a third assembly part 10 and a fourth assembly part 11 disposed at its top, with the third assembly part 10 and fourth assembly part 11 facing the two adjacent adjusting cylinders 4; the third assembly part 10 of each adjusting cylinder 4 and the fourth assembly part 11 of the adjacent bottom cylinder 3 are connected by a connecting mechanism. Figure 1-5 As shown, the first assembly part 8 and the second assembly part 9 at the bottom and top of each bottom cylinder 3, as well as the third assembly part 10 and the fourth assembly part 11 at the top of the adjusting cylinder 4, have the same shape and size. They can be a cylindrical structure, which can be plugged or snapped into the bottom cylinder 3 structure using a connecting mechanism. The first assembly part 8 at the top and bottom of each bottom cylinder 3 and the second assembly part 9 at the same position of another bottom cylinder 3 are connected by a connecting mechanism. In this way, the four bottom cylinders 3 are connected together in sequence. The third assembly part 10 and the fourth assembly part 11 of the adjusting cylinder 4 are also connected together in sequence using a connecting mechanism, so that the bottom cylinders 3 and the adjusting cylinders 4 of the prefabricated frame can form a stable structure.
[0037] In some embodiments, the connecting mechanism includes a connecting rod 12, the two ends of which are respectively connected to the first assembly part 8, the second assembly part 9, the third assembly part 10, and the fourth assembly part 11. For example... Figure 1-5 As shown, in the connection of the prefabricated frame, the two sides of the prefabricated frame are respectively connected to the first assembly part 8, the second assembly part 9, the third assembly part 10 and the fourth assembly part 11 through the two ends of the connecting rod 12, so that the radial dimension of the connecting rod 12 is adapted to the first assembly part 8, the second assembly part 9, the third assembly part 10 and the fourth assembly part 11, so that they can be connected together by plugging or snapping.
[0038] In some embodiments, the connecting mechanism includes at least two connecting rods 12 and at least one connecting ring 13, wherein both ends of the connecting rods 12 and the connecting ring 13 are threaded, one end of each of the two connecting rods 12 is screwed to the connecting ring 13, and the other end of each connecting rod 12 is connected to the first assembly part 8, the second assembly part 9, the third assembly part 10, and the fourth assembly part 11, respectively. Figure 1-5 As shown, in the connection of the prefabricated frame, the front and rear faces of the prefabricated frame are first connected together by a connecting ring 13 between two connecting rods 12. The connecting ring 13 and the connecting rods 12 are connected together by threads. Then, the other two ends of the two connecting rods 12 are respectively inserted or snapped into the first assembly part 8, the second assembly part 9, the third assembly part 10, and the fourth assembly part 11. It should be noted that the radial dimension of the connecting rods 12 is adapted to the first assembly part 8, the second assembly part 9, the third assembly part 10, and the fourth assembly part 11.
[0039] In some embodiments, the adjusting mechanism includes a first telescopic rod 14 and a second telescopic rod 15, the telescopic ends of the first telescopic rod 14 and the second telescopic rod 15 are connected, and the first telescopic rod 14 and the second telescopic rod 15 are arranged perpendicularly to each other; a fifth assembly part 16 is provided on the top of the two adjusting cylinders 4 near the working surface, the fifth assembly part 16 is respectively connected to the fixed end of the first telescopic rod 14, and the fixed end of the second telescopic rod 15 abuts against the working surface. Figure 1-5As shown, the adjustment mechanism includes a first telescopic rod 14 and a second telescopic rod 15. The telescopic ends of the first telescopic rod 14 and the second telescopic rod 15 are vertically connected, which can be done by bonding, snapping, or welding. The fixed end of the first telescopic rod 14 is snapped or inserted into the fifth assembly part 16 located on the top of the adjustment cylinder 4. The fixed end of the first telescopic rod 14 and the fifth assembly part 16 are adapted to each other. The overall length of the first telescopic rod 14 is the same as the width of the working surface. The second telescopic rod 15 is adjusted so that its end abuts against the working surface. In this way, the first telescopic rod 14 and the second telescopic rod 15 form a support for the second protective cover 2. At the same time, the first telescopic rod 14 and the second telescopic rod 15 are adjusted according to the height of the working surface relative to the ground and the width of the working surface so that they abut against the working surface. The adjustment of the first telescopic rod 14 and the second telescopic rod 15 can be achieved by setting through holes at their telescopic ends and fixed ends respectively. After bolts and nuts pass through the through holes, the nuts are screwed into the bolts so that the nuts abut against each other to fix them together.
[0040] In some embodiments, the two outer sides and the outer top of the first protective cover 1 are respectively provided with multiple sets of female Velcro closures 17, and the inner top and the two inner sides of the second protective cover 2 near the edge of the assembled frame are respectively provided with a set of female Velcro closures 18. The first protective cover 1 and the second protective cover 2 are connected by the female Velcro closures 17 and the female Velcro closures 18. Figure 1-5 As shown, the first protective cover 1 and the second protective cover 2 can be distinguished from each other by pre-set folds. The first protective cover 1 and the second protective cover 2 can be made of rainproof cloth, which is commercially available. The two outer sides and the rear end of the first protective cover 1 near the bottom of the bottom cylinder 3 have gaps, so that when the height of the assembled frame is adjusted, the two outer sides and the rear end near the bottom can be rolled up or unrolled, so that the height of the first protective cover 1 can be adjusted. The second protective cover 2 is the same, with gaps on its end face away from the assembled frame and its two sides near the working surface. A gap is provided to allow adjustment of the height of the second protective cover 2. The female hook and loop fastener 17 of the first protective cover 1 and the male hook and loop fastener 18 of the second protective cover 2 are connected to each other. The female hook and loop fastener 17 extends from the working surface to the side away from it. Thus, when the length of the first telescopic rod 14 is changed after the adjustment mechanism is adjusted, the second protective cover 2 can be attached to the first protective cover 1 in the direction away from the working surface. This allows the second protective cover 2 to be adjusted according to the width of the working surface, and the final first protective cover 1 and the second protective cover 2 are adapted to the working surface, reducing the spread of dust.
