[0043] See also Figure 1-10The present invention provides a technical solution: a freely positionable mobile dust suppression device for decoration design, comprising a base 1, a screw rod 2, a first bevel gear 3, a second bevel gear 4, a turning handle 5, a connecting plate 6, a supporting seat 7, a universal wheel 8, a fixing frame 9, a moving wheel 10, a dust collecting device 11, a bellows 12, a dust collecting hood 13, an activated carbon filter purification net 14, a fixing frame 15, a limiting mechanism 16, a fixing block 17, a protrusion 18, a fixing column 19, a first spring 20, a limiting plate 21, a fixing bolt 22, a connecting column 23, a mounting block 24, a fixing mechanism 25, a mounting plate 26, a second spring 27, a movable block 28, a movable plate 29, a fixing sleeve 30, a limiting frame 31 and a mounting column 32.

[0044] When using the freely positionable mobile dust suppression device for decoration design, if Figure 1 and Figure 3 As shown, both left and right ends of the base 1 are slidably connected with connecting plates 6, and the side of the connecting plate 6 away from the vertical central axis of the base 1 is fixedly connected to the support seat 7 by bolts, the lower end of the support seat 7 is installed with a universal wheel 8, and the lower end of the base 1 is installed with a moving wheel 10, the support seat 7 is placed on the ground through the universal wheel 8, the base 1 is placed on the ground through the moving wheel 10, the pushing device is moved through the universal wheel 8 and the moving wheel 10, the device is transferred to the corresponding position, and then the use length of the device is adjusted according to the actual space, by rotating as shown in FIG. Figure 1 and Figure 2 The turning handle 5 shown in the figure rotates on the base 1, and the lower end of the turning handle 5 is fixedly connected with the second bevel gear 4, and the second bevel gear 4 is meshingly connected with the first bevel gear 3. At the same time, the first bevel gear 3 is fixedly connected to the left and right ends of the screw rod 2, respectively. The turning handle 5 drives the screw rod 2 to rotate in the middle part of the base 1 through the first bevel gear 3 and the second bevel gear 4, and the screw rod 2 is connected to the connecting plate 6 by means of threads, and the threads at the left and right ends of the screw rod 2 are in opposite directions.

[0045] The connecting plate 6 and the base 1 are driven to slide by the screw rod 2, and the connecting plate 6 drives the support seat 7 and the base 1 to form a telescopic structure, so that the distance between the support seat 7 and the base 1 can be adjusted, and the position of the dust cover 13 can be adjusted, and then the support seat 7 is locked. Figure 1 , Figure 5 , Figure 6 , Figure 8 and Fig.10As shown, the dust hood 13 is connected to the suction end of the dust collection device 11 through the bellows 12, the dust collection device 11 is installed at the upper end of the base 1, and the dust hood 13 and the fixing frame 9 are connected by means of a slot, the fixing frame 9 is fixedly connected to the upper end of the support seat 7 by bolts, the front and rear ends of the dust hood 13 close to the vertical central axis of the base 1 are fixedly connected with connecting columns 23, the middle part of the connecting column 23 is fixedly connected with a mounting block 24 with a square structure, and the connecting column 23 and the fixing frame 9 are rotatably connected, the dust hood 13 forms a flip structure at the upper end of the fixing frame 9 through the connecting column 23, and the connecting column 23 and the fixing frame 9 are limited by a fixing mechanism 25, the fixing mechanism 25 includes a mounting plate 26 arranged on the side of the connecting column 23 away from the vertical central axis of the fixing frame 9, a second spring 27 arranged at the edge of the mounting plate 26, a movable block 28 fixedly connected to the movable end of the second spring 27, a movable plate 29 connected to the movable block 28 by a hinged manner, and a fixing sleeve 30 with a limiting function.

[0046] The movable plate 29 forms a flip structure on the side of the movable block 28 away from the vertical central axis of the base 1, and the movable block 28 is connected to the mounting plate 26 by sliding. At the same time, limit frames 31 are set at equal angles on the front and rear sides of the fixed frame 9. The interior of the limit frame 31 is fixedly connected with a mounting column 32 with a threaded outer surface. The mounting block 24 is inserted into the middle of the mounting plate 26. When the mounting plate 26 is rotated, the mounting plate 26 drives the connecting column 23 to rotate on the upper end of the fixed frame 9 through the mounting block 24, so that the angle of the dust hood 13 can be freely adjusted according to actual usage, so that the dust hood 13 can be better aligned with the source of dust generated during the decoration process, thereby achieving a better dust reduction effect.

[0047] After the angle adjustment of the dust hood 13 is completed, the movable plate 29 is rotated to the side away from the vertical central axis of the fixed frame 9, and a torsion spring is provided at the connection between the movable plate 29 and the movable block 28. At this time, the torsion spring undergoes elastic deformation, and then the movable block 28 is pulled to the side away from the vertical central axis of the base 1, and the movable block 28 slides with the mounting plate 26, and the movable block 28 squeezes the second spring 27, so that the second spring 27 undergoes elastic deformation. Then the movable plate 29 is aligned with the limit frame 31 at the corresponding position, and the inner part of the limit frame 31 is fixedly connected with the mounting column 32, and the movable plate 29 is released. At this time, the torsion spring at the connection between the movable plate 29 and the movable block 28 undergoes elastic deformation, driving the movable plate 29 to rotate to the side close to the vertical central axis of the fixed frame 9, and then the movable block 28 is released, and at this time, the second spring 27 recovers its elastic deformation.

[0048] The movable block 28 is pushed to slide with the mounting plate 26. At this time, the movable block 28 drives the movable plate 29 to be sleeved on the outer surface of the mounting column 32. Through the engagement between the movable plate 29 and the mounting column 32, the mounting plate 26 and the fixing frame 9 can be limited, thereby fixing the connecting column 23 and the fixing frame 9, which is convenient for freely positioning the dust hood 13 and the fixing frame 9, and has high practicality. Then, the fixing sleeve 30 threadedly connected to the outer surface of the mounting column 32 can be rotatably connected, so that the fixing sleeve 30 and the side of the movable plate 29 are fitted, and the mounting column 32 and the movable plate 29 can be further limited by the fixing sleeve 30, and the fastening is good. In addition, the dust hood 13 is connected to the suction end of the dust collection device 11 through the bellows 12. Since the bellows 12 can be deformed in a certain state, the dust hood 13 interferes with the bellows 12 when the angle of the dust hood 13 is adjusted.

[0049] After the fixing is completed, the dust collecting device 11 installed on the upper end of the base 1 is started. The dust collecting device 11 uses the bellows 12 to collect dust through the dust collecting hood 13, and can suck the dust in the design and construction process into the dust collecting hood 13 to reduce dust in the construction environment. Figure 1 , Figure 7 and Fig. 9 As shown, an activated carbon filter purification net 14 is arranged inside the dust cover 13, and the activated carbon filter purification net 14 is fixedly connected to the middle of the fixing frame 15. The setting of the activated carbon filter purification net 14 prevents dust from directly entering the dust collection device 11 and causing damage to the dust collection device 11. When the use is over, the dust collection device 11 is turned off. Figure 1 and Figure 4 As shown, limiting mechanisms 16 are provided at both upper and lower ends of the fixed frame 15, and a disassembly structure is formed between the fixed frame 15 and the dust hood 13 through the limiting mechanism 16. The limiting mechanism 16 includes a fixing block 17 fixedly connected to the upper and lower ends of the side surface of the fixed frame 15, a convex block 18 with a positioning function, a fixing column 19 with a "T"-shaped structure, a first spring 20 sleeved on the outer surface of the fixing column 19, a limiting plate 21 fixedly connected to the movable end of the first spring 20, and a fixing bolt 22 with a limiting function.

[0050] The fixing block 17 is then pulled outwardly, and the fixing block 17 is then disengaged from the fixing frame 15 and the dust hood 13, thereby facilitating the removal of the dust from the dust hood 13 and cleaning the dust on the fixing frame 15.
