Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, specifically to an automatic floor opening and closing dust control device. Background Technology

[0002] During construction, dust pollution mainly comes from on-site earthwork leveling, sawdust from the woodworking workshop, concrete mixing, and the transportation and handling of materials such as cement, stone, and backfill soil. These processes generate a large amount of dust pollution that affects air quality.

[0003] As construction site dust control standards and requirements continue to rise, the requirements for dustproof mesh netting on each floor are becoming increasingly stringent. Traditionally, dustproof mesh netting on each floor of a construction site is fixed using pressed wooden strips and steel nails. This not only damages the surface structure of existing components but also causes many inconveniences for work on the outer edges of the floors due to the mesh netting. Workers often forcibly pull and tug at the already sealed dustproof mesh netting for ease of construction, resulting in large-scale damage to the mesh netting on each floor and increasing labor and material costs. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic opening and closing dust control device for floors, so as to solve the problems of structural surface damage, inconvenient construction on the outer edge of the floor, and increased labor and material costs caused by the traditional floor dustproof mesh fixing method mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic floor opening and closing dust control device, comprising: an elastic connecting component, wherein two sets of elastic connecting components are provided, the elastic connecting component includes a cylinder, one end of the cylinder is slidably engaged with a moving rod, the end of the moving rod away from the cylinder is elastically connected to a sliding rod, a push plate is fixedly installed on the end of the sliding rod away from the moving rod and the end of the cylinder away from the moving rod, an installation groove is fixedly installed on the side wall of one end of each of the two push plates, a fixing plate is installed between the two installation grooves, and a pressure plate is connected to the upper end of each of the two installation grooves through a telescopic rod;

[0006] Both sets of elastic connecting components are equipped with fixing components on the left and right sides. The fixing components include pressure plate two and pressure plate three, which are elastically connected to each other.

[0007] Preferably, the cylinder has several limiting holes penetrating its sidewalls on the upper and lower sides of the end away from the push plate. The moving rod has grooves on the upper and lower sidewalls of one end. A spring is fixedly installed in each groove, and a limiting post is slidably inserted in each groove. The inner end of the limiting post is fixedly connected to the other end of the spring. The outer end of the limiting post has an arc-shaped chamfer. One end of the moving rod is slidably inserted into the cylinder, and one end of the limiting post is inserted into one of the limiting holes by compressing the spring.

[0008] Preferably, a moving groove is provided at the other end of the moving rod, and a second spring is fixedly installed in the moving groove. The end of the slide rod away from the push plate is slidably inserted into the moving groove and fixedly connected to the other end of the second spring.

[0009] Preferably, an anti-slip pad is fixedly installed on the side wall of the push plate away from the mounting groove. The mounting groove is U-shaped, and one end of the mounting groove is welded to the side wall of the push plate. A support plate is also fixedly installed on the side wall of the push plate. The support plate is perpendicular to the push plate and is located below the mounting groove.

[0010] Preferably, a hand-tightening bolt is threaded onto the lower sidewall of the mounting groove. One end of the hand-tightening bolt passes through the lower sidewall of the mounting groove, and both ends of the fixing plate are inserted into the mounting groove. The upper end of the hand-tightening bolt is tightened to make it tightly contact the lower sidewall of the fixing plate.

[0011] Preferably, the lower end of the telescopic rod is located at the upper end of the mounting groove, and the upper end of the telescopic rod is in contact with the lower side of one end of the pressure plate, thus supporting the pressure plate.

[0012] Preferably, a rubber block is fixedly installed on the lower side wall of the pressure plate two, and two round holes are symmetrically opened on the front and rear sides of the upper end of the pressure plate two.

[0013] Preferably, a rubber block 2 is fixedly installed on the upper end of the pressure plate 3, and two support columns are symmetrically fixedly installed on the front and rear sides of the lower end of the pressure plate 3, with a spring 3 fixedly installed at the lower end of each support column.

[0014] Preferably, the lower end of the support column is slidably inserted into the circular hole, and the lower end of the spring three is fixedly connected to the inner wall of the bottom end of the circular hole.

Then, press the pressure plate onto the upper or lower end of the dustproof mesh, ensuring it contacts the upper inner wall of the doorway or the ground. Next, position the lower end of the telescopic rod at the upper end of the mounting groove, and compress the telescopic rod until its upper end contacts the lower side of one end of the pressure plate. The first support plate is used to fix the upper end of the dustproof mesh inside the doorway. Before fixing the second and third pressure plates, the left and right sides of the dustproof mesh are laid on the inner walls of the left and right sides of the doorway. Then, the second and third pressure plates are fixed between the two support plates at the upper and lower ends, and one end of the dustproof mesh is pressed against the left and right side walls of the doorway, thus fixing the dustproof mesh. The construction is convenient and will not cause damage to the dustproof mesh or the surface structure of the existing components. The device can also be reused, saving costs.

In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0029] Please see Figures 1 to 6This invention provides a technical solution: an automatic floor opening and closing dust control device, comprising: two sets of elastic connecting components, each including a cylinder 1, with a movable rod 3 slidably engaged at one end of the cylinder 1, and a sliding rod 9 elastically connected to the end of the movable rod 3 away from the cylinder 1. Push plates 10 are fixedly installed at both the end of the sliding rod 9 away from the movable rod 3 and the end of the cylinder 1 away from the movable rod 3. An anti-slip pad 11 is fixedly installed on the side wall of the end of the push plate 10 away from the mounting groove 12. Several limiting holes 2 penetrating the side walls are provided on the upper and lower side walls of the end of the cylinder 1 away from the push plate 10. Grooves 4 are provided on the upper and lower side walls of one end of the movable rod 3. A spring 5 is fixedly installed in each groove 4, and a limiting post 6 is slidably inserted in each groove 4. The inner end of the limiting post 6 is fixedly connected to the other end of the spring 5. The outer end of the limiting post 6 has an arc-shaped chamfer. The diameter of the limiting post 6 is smaller than the diameter of the limiting hole 2. One end of the moving rod 3 is slidably inserted into the cylinder 1. One end of the limiting post 6 is inserted into one of the limiting holes 2 through the compression spring 5, thus engaging the moving rod 3 in the cylinder 1. By engaging the limiting post 6 with different limiting holes 2, the position of the moving rod 3 in the cylinder 1 can be changed, thereby changing the length between the cylinder 1 and the moving rod 3. This allows the elastic connecting component to be installed in doorways of buildings of different widths.

[0030] A moving groove 7 is provided at the other end of the moving rod 3. A spring 8 is fixedly installed in the moving groove 7. The end of the slide rod 9 away from the push plate 10 is slidably inserted into the moving groove 7 and fixedly connected to the other end of the spring 8. The combined length of the cylinder 1, the moving rod 3 and the slide rod 9 is slightly greater than the width of the door opening to be covered. Then, by compressing the spring 8, the cylinder 1, the moving rod 3 and the slide rod 9 are placed into the door opening. Then, the external force is removed. Under the reaction force of the spring 8, the push plate 10 and the anti-slip pad 11 are pushed outward, so that the anti-slip pad 11 is in close contact with the side wall of the door opening, thereby fixing it. Before fixing the elastic connecting parts, the dustproof mesh 25 to be covered is cut to a size larger than the door opening to be covered. The two ends of the dustproof mesh 25 are fixed to the anti-slip pad 11, thereby pre-fixing the left and right ends of the dustproof mesh 25 to the door opening.

[0031] Two push plates 10 each have a U-shaped mounting groove 12 fixedly installed on one side wall. One end of the mounting groove 12 is welded to the side wall of the push plate 10. A support plate 17 is also fixedly installed on the side wall of the push plate 10. The support plate 17 is perpendicular to the push plate 10 and is located below the mounting groove 12. A fixing plate 14 is installed between the two mounting grooves 12. The upper ends of the two mounting grooves 12 are connected to pressure plates 15 via telescopic rods 16. A hand-tightening bolt 13 is threaded onto the lower side wall of the mounting groove 12. One end of the hand-tightening bolt 13 passes through the lower side wall of the mounting groove 12. Both ends of the fixing plate 14 are inserted into the mounting grooves 12. By tightening the hand-tightening bolt 13, its upper end is made to contact the lower side wall of the fixing plate 14 tightly, thus fixing the elastic connecting component and preventing it from being accidentally pulled out of the doorway under external force.

[0032] Then press the pressure plate 15 onto the upper or lower end of the dustproof mesh 25, and make it contact the upper inner wall of the doorway or the ground. Then place the lower end of the telescopic rod 16 at the upper end of the mounting groove 12. By compressing the telescopic rod 16, make the upper end of the telescopic rod 16 contact the lower side of one end of the pressure plate 15, support the pressure plate 15, and thus fix the upper end of the dustproof mesh 25 inside the doorway.

[0033] Both sets of elastic connecting components have fixing components on their left and right sides. The fixing components include pressure plate 218 and pressure plate 31. Pressure plate 218 and pressure plate 31 are elastically connected. A rubber block 10 is fixedly installed on the lower side wall of pressure plate 218. Two round holes 19 are symmetrically opened on the front and rear sides of the upper end of pressure plate 21. A rubber block 24 is fixedly installed on the upper end of pressure plate 31. Two support columns 22 are symmetrically fixedly installed on the front and rear sides of the lower end of pressure plate 31. A spring 33 is fixedly installed on the lower end of each support column 22. The lower end of the support column 22 slides into the round hole 19. The lower end of the spring 33 is fixedly connected to the bottom inner wall of the round hole 19. By compressing the spring 33, the support column 22 can slide in the round hole 19, thereby changing the distance between pressure plate 218 and pressure plate 31, so that pressure plate 218 and pressure plate 321 can be installed in door openings of different heights.

[0034] The lower end of the pressure plate 218 is placed on the support plate 17 on the elastic connecting component at the lower end via the rubber block 20. The upper end of the pressure plate 321 is in close contact with the lower side wall of the support plate 17 on the elastic connecting component at the upper end via the rubber block 24. At this time, the spring 323 is in a compressed state. Before fixing the pressure plate 218 and the pressure plate 321, the left and right sides of the dustproof mesh are laid on the inner walls of the left and right sides of the door opening. Then, the pressure plate 218 and the pressure plate 321 are fixed between the two support plates 17 at the upper and lower ends, and one end of the dustproof mesh 25 is pressed against the left and right side walls of the door opening, thereby fixing the dustproof mesh.

[0035] When this device is in operation, the dustproof mesh 25 to be covered is cut to a size larger than the door opening to be covered. Both ends of the dustproof mesh 25 are fixed to the anti-slip pad 11. The elastic connecting component is then fixed inside the door opening, thus pre-fixing both ends of the dustproof mesh 25 to the door opening. Next, the pressure plate 15 is pressed onto the upper or lower end of the dustproof mesh 25, contacting the upper inner wall of the door opening or the ground. Then, the lower end of the telescopic rod 16 is positioned above the mounting groove 12, and the telescopic rod is compressed. 16. Make the upper end of the telescopic rod 16 contact the lower side of one end of the pressure plate 15 to support the pressure plate 15, thereby fixing the upper end of the dustproof mesh 25 inside the doorway. Before fixing the pressure plate 28 and the pressure plate 3 21, lay the left and right sides of the dustproof mesh on the left and right inner walls of the doorway. Then fix the pressure plate 28 and the pressure plate 3 21 between the two support plates 17 at the upper and lower ends, and press the dustproof mesh 25 against the left and right side walls of the doorway at one end, thereby fixing the dustproof mesh.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
