[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1.

By pulling the movable ring, the first steel pipe, the second steel pipe and the third steel pipe can be connected, which simplifies the installation steps of building a scaffold with steel pipes, thereby solving the problem that when building a scaffold between steel pipes, multiple fasteners need to be installed and the fasteners need to be tightened and fixed, which makes the installation of scaffolds for house construction inconvenient.

[0018] 2. When the first steel pipe, the second steel pipe and the third steel pipe are connected, the limiting block is engaged with the second circular hole and the inner wall of the first circular hole on the first steel pipe and the second steel pipe, thereby limiting the mutual movement between the first steel pipe, the second steel pipe and the third steel pipe, preventing the first steel pipe and the second steel pipe from sliding between the first limiting plate and the inner wall of the second limiting plate, thereby ensuring the stability of the mutual connection between the first steel pipe, the second steel pipe and the third steel pipe.

[0019] 3. When the ground is uneven during installation of the scaffold, the motor is used to drive the screw to rotate, thereby driving the outer surface of the third steel pipe to move along the inner wall of the fixed axis.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] See also Figure 1-8The present invention provides a technical solution: a scaffold for house construction that is easy to install, comprising: two first steel pipes 1, two second steel pipes 2 and two third steel pipes 3, the outer surfaces of the two first steel pipes 1 are each provided with two fixing components 4 for fixing the second steel pipe 2, the outer surfaces of the two third steel pipes 3 are each provided with a fixing component 4 for fixing the first steel pipe 1, the six fixing components 4 each include a first limiting plate 402, the outer surfaces of the six first limiting plates 402 are each fixedly connected with the first limiting plates 402 near the edges on both sides, the outer surfaces of the twelve first limiting plates 402 are each fixedly connected with the second fixing blocks 403, the outer surfaces of the twelve second fixing blocks 403 are each provided with a first spring 405, one end of the twelve first springs 405 are each fixedly connected with a moving block 406, the outer surfaces of the twelve moving blocks 406 are each fixedly connected with a moving ring 407, the six first limiting plates 402 are respectively welded to the outer surfaces of the two first steel pipes 1 and the two third steel pipes 3, the twelve The other end of the first spring 405 is fixedly connected to the outer surface of the twelve second fixed blocks 403 respectively, and the inner walls of the twelve second fixed blocks 403 are slidably connected with the moving shaft 404. The other ends of the twelve moving shafts 404 are fixedly connected to the outer surface of the twelve moving blocks 406 respectively, and the outer surfaces of the other sides of the six first fixed blocks 401 are fixedly connected with the connecting plate 408. The outer surfaces of the six connecting plates 408 are fixedly connected with the second limiting plate 409. The inner walls of the six second limiting plates 409 are fixedly sleeved on the outer surfaces of the two first steel pipes 1 and the two third steel pipes 3 respectively. The inner walls of the six second limiting plates 409 are fixedly installed with the third fixed block 410. The inner walls of the four first limiting plates 402 and the two second limiting plates 409 fixedly installed on the outer surfaces of the two third steel pipes 3 are in contact with the outer surfaces of the two first steel pipes 1 respectively, and the inner walls of the twelve moving rings 407 are in contact with the outer surfaces of the two second steel pipes 2 and the two first steel pipes 1 respectively.

[0032] In this embodiment, a scaffold for house construction that is easy to install needs to be connected to the first steel pipe 1, the second steel pipe 2 and the third steel pipe 3 during the construction process. A plurality of fixing components 4 are fixedly installed on the first steel pipe 1. The staff needs to first connect the outer surface of the second steel pipe 2 near one end to the fixing component 4. At this time, the staff needs to move the movable shaft 404 first. The outer surface of the movable shaft 404 will slide on the inner wall of the second fixed block 403. At the same time, the movable shaft 404 will drive the movable block 406 to move when it moves. The movable block 406 will drive the movable ring 407 to move when it moves. At the same time, the movable block 406 will squeeze the first spring 405 when it moves until the center of the movable ring 407 is aligned with the first limit plate 402. When the center of the intersection of the second limit plate 409 and the second limit plate 409 is on the same horizontal line, the staff inserts the outer surface of the second steel pipe 2 along the inner wall of one of the moving rings 407, and the outer surface of the second steel pipe 2 will contact the moving ring 407, the first limit plate 402, the second limit plate 409, the first limit plate 402 and the inner wall of the moving ring 407 in sequence. When the second steel pipe 2 is moved to the appropriate position, the staff no longer holds the moving shaft 404, and the elastic force of the first spring 405 itself will drive the moving block 406 to move, and the moving block 406 will drive the moving ring 407 to move. Since the second steel pipe 2 is located between the first limit plate 402 and the second limit plate 409 at this time, the second steel pipe 2 will not move, and the moving ring 407 It is sleeved on the outer surface of the second steel pipe 2, and the moving ring 407 will not move, so that the elastic force of the first spring 405 will be applied to the moving ring 407 through the moving block 406, and the moving ring 407 will generate a force applied to the outer surface of the second steel pipe 2, thereby limiting the movement of the second steel pipe 2, and the second steel pipe 2 and the first steel pipe 1 are connected to each other, and then the other end of the second steel pipe 2 is connected to another first steel pipe 1 in the same way. After the second steel pipe 2 is connected to the first steel pipe 1, the staff needs to connect the outer surface of the first steel pipe 1 with the fixing component 4 on the outer surface of the third steel pipe 3. The connection method is the same as the connection method of the second steel pipe 2 and the first steel pipe 1. The lengths between the first steel pipe 1, the second steel pipe 2 and the third steel pipe 3 in this device are It can be adjusted according to the actual scaffolding. The number and position of the fixing components 4 on the first steel tube 1 can be adjusted by the number of the second steel tubes 2 installed on the first steel tube 1. The number and position of the fixing components 4 on the third steel tube 3 can be adjusted by the number of the third steel tube 3 that needs to be connected to the first steel tube 1. In this device, when the first steel tube 1, the second steel tube 2 and the third steel tube 3 need to be connected, the first steel tube 1 can be inserted into the first limiting plate 402 and the second limiting plate 409 on the third steel tube 3, and the second steel tube 2 can be inserted into the first limiting plate 402 and the second limiting plate 409 on the first steel tube 1. The elastic force of the first spring 405 itself will be converted into pressure to act on the outer surfaces of the first steel tube 1 and the second steel tube 2 located on the inner wall of the movable ring 407.By restricting its movement, the first steel pipe 1, the second steel pipe 2, and the third steel pipe 3 can be connected by pulling the movable ring 407, simplifying the installation steps of the steel pipes into a scaffold, thereby solving the problem of the inconvenience of installing scaffolds for building construction, which requires installing multiple fasteners when building a scaffold between steel pipes and tightening the fasteners.

[0033] like Figure 1-8 As shown, the outer surfaces of the six third fixed blocks 410 are fixedly connected to the sliding shaft 411, the outer surfaces of the six sliding shafts 411 are slidably connected to the limiting blocks 412, and the outer surfaces of the six third fixed blocks 410 are provided with second springs 413, one end of the six second springs 413 is respectively fixedly connected to the outer surfaces of the six third fixed blocks 410, and the other ends of the six second springs 413 are respectively fixedly connected to the outer surfaces of the six limiting blocks 412, and the inner walls of the eight first limiting plates 402 and the four second limiting plates 409 fixedly installed on the outer surfaces of the two first steel pipes 1 are respectively in contact with the outer surfaces of the two second steel pipes 2.

[0034] When the second steel pipe 2 is moved to a suitable position, the first circular hole 6 on the second steel pipe 2 is located on the outer surface of the limit block 412, and the outer surface of the limit block 412 is in contact with the inner wall of the limit block 412. The surface is no longer in contact with the outer surface of the second steel pipe 2, and the extrusion force is eliminated, so that the elastic force of the second spring 413 itself drives the limit block 412 to move, and the inner wall of the limit block 412 slides along the outer surface of the sliding shaft 411 until the outer surface of the limit block 412 slides into the inner wall of the first circular hole 6. At this time, the outer surface of the limit block 412 contacts and engages with the inner wall of the first circular hole 6. When the first steel pipe 1 is connected to the third steel pipe 3, the limit block 412 on the third steel pipe 3 is The outer surface will contact and engage with the inner wall of the second circular hole 7, and engage with the inner walls of the second circular hole 7 and the first circular hole 6 on the first steel pipe 1 and the second steel pipe 2 through the limit block 412, thereby limiting the mutual movement between the first steel pipe 1, the second steel pipe 2 and the third steel pipe 3, preventing the first steel pipe 1 and the second steel pipe 2 from sliding between the inner walls of the first limit plate 402 and the second limit plate 409, and ensuring the stability of the mutual connection between the first steel pipe 1, the second steel pipe 2 and the third steel pipe 3.

[0035] like Figure 1-8As shown, one end of the two third steel tubes 3 is provided with a moving component 5, and the two moving components 5 include a base 501. One end of the two third steel tubes 3 is movably embedded in the inner wall of the two bases 501. The outer surfaces of the two bases 501 are fixedly connected with a fixed shaft 502. The inner walls of the two fixed shafts 502 are provided with two sliding grooves 503. The inner walls of the four sliding grooves 503 are slidably connected with sliders 504. Each adjacent two sliders 504 form a group. The outer surface of each group of sliders 504 is fixedly connected to the outer surface of the two third steel tubes 3. The outer surfaces of the two third steel tubes 3 are respectively connected to the two fixed shafts 502. The inner walls of the two bases 501 slide with each other, and motors 505 are provided on the inner walls of the two bases. The output ends of the two motors 505 are fixedly connected with output shafts 506, and the outer surfaces of the two output shafts 506 are fixedly sleeved with first gears 507. The inner walls of the two third steel pipes 3 are threadedly connected with screw rods 508 near one end, and the inner walls of the two screw rods 508 are fixedly connected with second gears 509. The outer surfaces of the two first gears 507 are respectively engaged with the outer surfaces of the two second gears 509. The outer surfaces of the two second steel pipes 2 are provided with two first circular holes 6, and the outer surfaces of the two first steel pipes 1 are provided with second circular holes 7.

[0036] In this embodiment, a scaffold for house construction that is easy to install is being erected. When the first steel pipe 1, the second steel pipe 2 and the third steel pipe 3 are connected, the third steel pipe 3 is perpendicular to the horizontal ground. When the ground is uneven during the connection, the staff starts the motor 505, the motor 505 drives the output shaft 506 to rotate, the output shaft 506 drives the first gear 507 to rotate, the first gear 507 drives the meshed second gear 509 to rotate, and when the second gear 509 rotates, it drives the screw rod 508 to rotate. The outer surface of the screw rod 508 rotates spirally on the inner wall of the third steel pipe 3, thereby driving the inner wall of the third steel pipe 3 along The outer surface of the screw rod 508 moves spirally, and the third steel pipe 3 will drive the outer surface of the slider 504 to slide along the inner wall of the slide groove 503 when moving. At the same time, the outer surface of the third steel pipe 3 slides along the inner wall of the fixed shaft 502 until the horizontal position of the third steel pipe 3 is the same as the horizontal position of other third steel pipes 3. In this device, the motor 505 is used to drive the screw rod 508 to rotate, thereby driving the outer surface of the third steel pipe 3 to move along the inner wall of the fixed shaft 502. The movement of the third steel pipe 3 can change the distance between one end of the third steel pipe 3 and the ground, so that the third steel pipe 3 can adapt to uneven ground, thereby improving the applicability of scaffolding for house construction that is easy to install.

[0037] The method of using and the working principle of this device: During the construction of a scaffold for house construction that is easy to install, the first steel pipe 1, the second steel pipe 2 and the third steel pipe 3 are connected to each other, and the staff connects the outer surface of the second steel pipe 2 near one end to the fixed component 4 on the first steel pipe 1. At this time, the staff needs to move the movable shaft 404, and the movable shaft 404 will drive the movable ring 407 to move, and at the same time, the first spring 405 will be squeezed until the center of the movable ring 407 is on the same horizontal line as the center of the intersection of the first limit plate 402 and the second limit plate 409. Then the outer surface of the second steel pipe 2 is inserted in sequence along the inner wall of the movable ring 407, the first limit plate 402, the second limit plate 409, the first limit plate 402 and the movable ring 407. When the outer surface of the second steel pipe 2 contacts the inner wall of the second limit plate 409, the outer surface of the second steel pipe 2 will drive the limit block 412 to move. When the limit block 412 moves The second spring 413 will be squeezed. When the second steel pipe 2 is moved to the appropriate position, the first circular hole 6 will be located on the outer surface of the limit block 412. The elastic force of the second spring 413 itself will drive the limit block 412 to slide into the inner wall of the first circular hole 6. At the same time, the staff no longer holds the movable shaft 404. The elastic force of the first spring 405 itself will be converted into pressure to act on the outer surface of the second steel pipe 2 located on the inner wall of the movable ring 407, limiting its movement. The third steel pipe 3 and the first steel pipe 1 are connected to each other in the same way. At the same time, when there is unevenness between the construction ground, the staff starts the motor 505, and the motor 505 will drive the first gear 507 to rotate. The first gear 507 will drive the second gear 509 to rotate. The second gear 509 will drive the screw rod 508 to rotate. The screw rod 508 will drive the inner wall of the third steel pipe 3 to move spirally along the outer surface of the screw rod 508, so that the horizontal position of the third steel pipe 3 is the same as the horizontal position of other third steel pipes 3.
