Description

Technical Field

[0001] This utility model relates to the field of waterproof coating painting technology, and specifically discloses a basement waterproof coating painting device. Background Technology

[0002] JS waterproof coating, a high-performance polymer cement-based waterproof coating, boasts advantages such as being environmentally friendly and non-toxic, possessing excellent elasticity, strong adhesion, and outstanding water resistance. After film formation, it creates a continuous and dense waterproof membrane on the substrate surface, effectively blocking groundwater penetration and providing long-term protection for concrete structures. In basement waterproofing projects, the application of JS waterproof coating is crucial. It not only resists groundwater erosion and moisture penetration but also mitigates the risk of cracking caused by structural settlement, making it a key element in ensuring the long-term safe use of basements. Due to the complex space of basements, with multiple construction interfaces including walls, ceilings, and corners, a plastering device is necessary to fully cover the substrate surface with the waterproof coating.

[0003] However, the basement waterproofing coating painting devices commonly available on the market have significant shortcomings: First, the brush head and the main body of the device are mostly integrated and fixed, lacking a convenient disassembly and assembly mechanism. When the brush head is in contact with the coating and rough substrate for a long time, causing the bristles to wear or the structure to be damaged, it is impossible to disassemble and replace the brush head separately. The entire device must be discarded, resulting in material waste and increased construction costs. Second, the connecting rod of the device has a fixed length, which is difficult to adapt to the construction needs of walls, ceilings and narrow spaces of different heights in the basement. When the connecting rod is short, the construction workers need to climb or use scaffolding to adjust the operating height. When the connecting rod is long, it increases the difficulty of painting at lower levels, making the operation very inconvenient.

[0004] Therefore, a basement waterproofing coating application device is needed to solve the above problems. Utility Model Content

[0005] This utility model proposes a basement waterproof coating painting device. By setting up a disassembly and assembly mechanism, the brush tube with brush can be easily replaced, avoiding the need to discard the whole device, effectively reducing material waste and lowering construction costs. At the same time, the length adjustment mechanism allows for flexible adjustment of the overall length of the device, enabling it to adapt to the construction needs of basement walls and ceilings of different heights and narrow spaces, significantly improving ease of use.

[0006] This utility model is implemented as follows: a basement waterproof coating painting device includes a connecting rod and a brush cylinder with bristles on its outer surface. The outer wall of the connecting rod is rotatably connected to a rotating cylinder through multiple bearings. The brush cylinder is sleeved on the outer wall of the rotating cylinder. The outer wall of the brush cylinder is provided with a disassembly and assembly mechanism.

[0007] The disassembly and assembly mechanism includes a first limiting cover rotatably connected to the outside of the connecting rod via a sealed bearing. A first sealing ring is embedded in the left side of the first limiting cover through a groove, abutting against the right end of the brush cylinder. A disc is provided on the left side of the connecting rod. A second limiting cover is rotatably connected to the outer wall of the disc via a sealed bearing. A second sealing ring is embedded in the right side of the second limiting cover through a groove, abutting against the left end of the brush cylinder. A limiting square groove is formed at the right end of the disc. A limiting square post is fixedly connected to the left end of the connecting rod and inserted into the limiting square groove. A through hole is formed at the left end of the inner wall of the limiting square groove. A screw rod passing through the through hole is fixedly connected to the left end of the limiting square post. A hexagonal nut is threaded onto the outer wall of the screw rod.

[0008] The other end of the connecting rod is fixedly connected to a fixed plate. A length adjustment mechanism is provided on the lower side of the fixed plate. The length adjustment mechanism includes a round rod located below the fixed plate. A semi-circular plate is fixedly connected to the lower end of the fixed plate. A sliding groove is provided on the left end of the outer wall of the round rod. A slider fixedly connected to the semi-circular plate is slidably connected inside the sliding groove. The length adjustment mechanism also includes a locking mechanism.

[0009] As a preferred embodiment of the basement waterproof coating painting device of this utility model, the locking mechanism includes a plurality of evenly distributed limiting circular holes opened on the right side of the outer wall of the circular rod, a U-shaped frame fixedly connected to the right end of the semi-circular plate, a threaded post threaded through and threadedly connected to the outer wall of the U-shaped frame, a limiting post inserted into one of the limiting circular holes fixedly connected to the left end of the threaded post, and an anti-slip torsion block fixedly connected to the right end of the threaded post.

[0010] As a preferred embodiment of the basement waterproof coating painting device of this utility model, the outer wall of the rotating cylinder is provided with two limiting grooves, and the inner wall of the two limiting grooves is inserted with a limiting strip that is fixedly connected to the inner wall of the brush cylinder.

[0011] As a preferred embodiment of the basement waterproof coating application device of this utility model, a rubber gasket is abutting between the hexagonal nut and the disc.

[0012] As a preferred embodiment of the basement waterproof coating application device of this utility model, both the chute and the slider are dovetail-shaped structures that slide and cooperate with each other.

[0013] As a preferred embodiment of the basement waterproof coating application device of this utility model, a portion of the left side of the limiting square column is a conical structure.

[0014] As a preferred embodiment of the basement waterproof coating application device of this utility model, the left end of the limiting column is equipped with a tapered guide head.

[0015] The beneficial effects of this utility model are:

[0016] 1. During installation, align the limiting strip on the inner wall of the brush cylinder with the limiting groove on the outer wall of the rotating cylinder and insert it axially, ensuring the limiting strip is inserted into the limiting groove to form a circumferential limit, and that the brush cylinder contacts the first sealing ring. Then, align the limiting square groove of the disc with the limiting square post of the connecting rod and push it in until the screw passes through the through hole in the inner wall of the limiting square groove, and the second sealing ring of the second limiting cover contacts the end face of the brush cylinder. Finally, tighten the nut on the screw, pushing the disc to press against the second limiting cover, ensuring the first and second sealing rings tightly fit against both ends of the brush cylinder for bidirectional sealing. Simultaneously, the limiting square post and limiting square groove cooperate to restrict the rotation of the disc. When the bristles wear out and need replacement, simply loosen and remove the nut, slide the disc and second limiting cover horizontally to remove them, and then slide the brush cylinder axially to disengage the limiting strip from the limiting groove, thus removing the entire brush cylinder. This method allows for convenient replacement of the brush cylinder with bristles, avoids discarding the entire device, effectively reduces material waste, and lowers construction costs.

[0017] 2. According to the required construction height, hold the round rod and slide it vertically, causing the slider to move within the groove. After adjusting to the appropriate height, lock the semi-circular plate to the round rod using the locking mechanism to maintain length stability. The semi-circular plate design prevents obstruction of the limiting hole during operation, facilitating the alignment and insertion of the limiting post into the corresponding hole. This length adjustment mechanism allows for flexible adjustment of the overall length of the device, adapting to the construction needs of walls and ceilings of varying heights in basements and in narrow spaces, significantly improving ease of use.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-6 A basement waterproof coating painting device includes a connecting rod 1 and a brush cylinder 2 with bristles on its outer surface. The outer wall of the connecting rod 1 is rotatably connected to a rotating cylinder 3 through multiple bearings. The brush cylinder 2 is sleeved on the outer wall of the rotating cylinder 3. The outer wall of the brush cylinder 2 is provided with a disassembly and assembly mechanism.

[0028] The disassembly and assembly mechanism includes a first limiting cover 6 rotatably connected to the outside of the connecting rod 1 via a sealed bearing. A first sealing ring 7 is installed on the left side of the first limiting cover 6 through a groove, abutting against the right end of the brush cylinder 2. A disc 8 is provided on the left side of the connecting rod 1. A second limiting cover 9 is rotatably connected to the outer wall of the disc 8 via a sealed bearing. A second sealing ring 10 is installed on the right side of the second limiting cover 9 through a groove, abutting against the left end of the brush cylinder 2. A limiting square groove 11 is opened at the right end of the disc 8. A limiting square post 12 is fixedly connected to the left end of the connecting rod 1 and inserted into the limiting square groove 11. A through hole 13 is opened through the left end of the inner wall of the limiting square groove 11. A screw 24 passing through the through hole 13 is fixedly connected to the left end of the limiting square post 12. A hexagonal nut 14 is threadedly connected to the outer wall of the screw 24.

[0029] The other end of the connecting rod 1 is fixedly connected to a fixed plate 15. A length adjustment mechanism is provided on the lower side of the fixed plate 15. The length adjustment mechanism includes a round rod 17 located below the fixed plate 15. A semi-circular plate 16 is fixedly connected to the lower end of the fixed plate 15. A groove 18 is provided on the left end of the outer wall of the round rod 17. A slider 19 fixedly connected to the semi-circular plate 16 is slidably connected inside the groove 18. The length adjustment mechanism also includes a locking mechanism.

[0030] In this embodiment: when installing the brush cylinder 2 with bristles to the main body, align the limiting strip 5 on the inner wall of the brush cylinder 2 with the limiting groove 4 on the outer wall of the rotating cylinder 3, and sleeve it axially onto the outer wall of the rotating cylinder 3, so that the limiting strip 5 is fully inserted into the limiting groove 4 to form a circumferential limit, until the brush cylinder 2 contacts the first sealing ring 7 of the first limiting cover 6. Then, align the limiting square groove 11 of the disc 8 with the limiting square post 12 at the left end of the connecting rod 1, and push the disc 8 to insert the limiting square post 12 into the limiting square groove 11, until the screw 24 at the left end of the limiting square post 12 passes through the through hole 13 on the inner wall of the limiting square groove 11. Then, the second sealing ring 10 of the second limiting cover 9 is brought into contact with the left side of the brush cylinder 2. The rubber gasket is then placed on the outside of the screw 24, and the hexagonal nut 14 is screwed into the outer wall of the screw 24. The hexagonal nut 14 is then rotated with a wrench to move the hexagonal nut 14 to the right along the screw 24, pushing the disc 8 to the right to press the second limiting cover 9. This causes the second sealing ring 10 and the first sealing ring 7 to fit tightly against the left and right end faces of the brush cylinder 2, forming a bidirectional seal. At the same time, the cooperation between the limiting square post 12 and the limiting square groove 11 restricts the circumferential rotation of the disc 8, ensuring a stable installation. The installation is now complete.

[0031] When the bristles of the brush cylinder 2 are worn or damaged, use a wrench to rotate the hexagonal nut 14 in the opposite direction, so that it moves to the left along the screw 24 until the hexagonal nut 14 is completely disengaged from the screw 24. Remove the hexagonal nut 14 and the rubber washer, and then move the disc 8 to the left so that the limiting column 12 is pulled out from the limiting groove 11. Remove the second limiting cover 9, and then pull the brush cylinder 2 to the left along the axis of the rotating cylinder 3 so that the limiting strip 5 on the inner wall slides out from the limiting groove 4 of the rotating cylinder 3. The brush cylinder 2 can then be removed as a whole. In this way, the brush cylinder 2 with bristles can be easily replaced, avoiding the need to discard the whole device, effectively reducing material waste and lowering construction costs.

[0032] To adjust the overall length according to the construction needs of different heights in the basement, hold the round rod 17 and slide it up and down vertically, causing the slider 19 to slide synchronously in the groove 18. When the length of the device is adjusted to a suitable construction height, the locking mechanism locks the semi-circular plate 16 and the round rod 17 to ensure that the length remains unchanged during construction. Since the semi-circular plate 16 has a semi-circular structure, it prevents the limiting round hole 20 from being blocked during operation, making it easy to align the limiting post 23 and insert it into the corresponding limiting round hole 20. Thus, the overall length of the device can be flexibly adjusted with the length adjustment mechanism, so that it can adapt to the construction needs of different heights of walls, ceilings and narrow spaces in the basement, significantly improving the ease of use.

[0033] During use, when the bristles of the brush cylinder 2 contact the wall and roll, the rotating cylinder 3 rotates synchronously through the outer rings of multiple bearings. At the same time, the first limiting cover 6 and the second limiting cover 9 rotate through two sealed bearings respectively. Since the two sealed bearings and multiple bearings have low friction characteristics, the rotation of the brush cylinder 2 and the bristles can be ensured to be smooth and unobstructed. Meanwhile, the first sealing ring 7 and the second sealing ring 10 are respectively embedded in the grooves of the first limiting cover 6 and the second limiting cover 9, and tightly abut against the left and right end faces of the brush cylinder 2, effectively preventing paint from seeping into the inner cavity of the brush cylinder 2 from the connection.

[0034] As a technical optimization of this utility model, the locking mechanism includes a plurality of evenly distributed limiting circular holes 20 opened on the right side of the outer wall of the circular rod 17, a U-shaped frame 21 fixedly connected to the right end of the semi-circular plate 16, a threaded post 22 threaded through and threadedly connected to the outer wall of the U-shaped frame 21, a limiting post 23 inserted into one of the limiting circular holes 20 fixedly connected to the left end of the threaded post 22, and an anti-slip torsion block fixedly connected to the right end of the threaded post 22.

[0035] In this embodiment: when the device length is adjusted to a suitable construction height, the anti-slip torsion block is rotated, and the threaded column 22 drives the limiting column 23 to move to the left, so that the limiting column 23 is aligned and inserted into the corresponding limiting round hole 20 until the limiting column 23 is fully embedded. Then, through the mutual cooperation between the limiting column 23 and the limiting round hole 20, the semi-circular plate 16 and the round rod 17 are locked to ensure that the length remains unchanged during the construction process.

[0036] As a technical optimization of this utility model, two limiting grooves 4 are provided on the outer wall of the rotating cylinder 3, and limiting strips 5 that are fixedly connected to the inner wall of the brush cylinder 2 are inserted into the two limiting grooves 4.

[0037] In this embodiment: the limiting groove 4 on the outer wall of the rotating cylinder 3 and the limiting strip 5 on the inner wall of the brush cylinder 2 are inserted to form a circumferential limiting structure. During installation, the limiting strip 5 is inserted into the limiting groove 4 to prevent the brush cylinder 2 from rotating relative to the rotating cylinder 3, ensuring that the brush cylinder 2 and the rotating cylinder 3 rotate synchronously when the bristles roll. During disassembly, the brush cylinder 2 is pulled axially, and the limiting strip 5 slides out of the limiting groove 4, realizing the quick disassembly and assembly of the brush cylinder 2.

[0038] As a technical optimization of this utility model, a rubber gasket is provided between the hexagonal nut 14 and the disc 8.

[0039] In this embodiment, the rubber gasket between the hexagonal nut 14 and the disc 8 fills the gap between the contact surfaces through elastic deformation, increasing the friction of the threaded connection and preventing the hexagonal nut 14 from loosening due to vibration or external force.

[0040] As a technical optimization of this utility model, both the slide groove 18 and the slider 19 are dovetail-shaped structures that slide and cooperate with each other.

[0041] In this embodiment, since both the groove 18 and the slider 19 are dovetail-shaped structures that slide and engage with each other, the slider 19 is prevented from detaching from the inside of the groove 18.

[0042] As a technical optimization of this utility model, a portion of the left side of the limiting column 12 is a conical structure.

[0043] In this embodiment, the tapered structure on the left side of the limiting column 12 serves as a guide, guiding the limiting column 12 to quickly align with the limiting groove 11 during installation, reducing insertion difficulty and minimizing manual alignment time.

[0044] As a technical optimization of this utility model, the left end of the limiting post 23 is equipped with a tapered guide head.

[0045] In this embodiment, the tapered guide head at the left end of the limiting post 23 guides the limiting post 23 to quickly align with the limiting hole 20 when locking. Even if there is a deviation between the limiting post 23 and the limiting hole 20, the insertion direction can be automatically corrected by the tapered surface, thus improving the ease of operation of the locking mechanism.

[0046] The working principle and usage process of this utility model are as follows: When installing the brush cylinder 2 with bristles to the main body, align the limiting strip 5 on the inner wall of the brush cylinder 2 with the limiting groove 4 on the outer wall of the rotating cylinder 3, and axially fit it onto the outer wall of the rotating cylinder 3, so that the limiting strip 5 is fully inserted into the limiting groove 4 to form a circumferential limit, preventing the brush cylinder 2 from rotating relative to the rotating cylinder 3, until the brush cylinder 2 contacts the first sealing ring 7 of the first limiting cover 6. Then, align the limiting square groove 11 of the disc 8 with the limiting square post 12 at the left end of the connecting rod 1, and push the disc 8 to insert the limiting square post 12 into the limiting square groove 11, until the screw 24 at the left end of the limiting square post 12 passes through the limiting square groove. The inner wall of the brush cylinder 2 is pierced through the hole 13, and the second sealing ring 10 of the second limiting cover 9 is brought into contact with the left side of the brush cylinder 2. Then, the rubber gasket is placed on the outside of the screw rod 24, and the hexagonal nut 14 is screwed into the outer wall of the screw rod 24. Then, the hexagonal nut 14 is rotated with a wrench to move the hexagonal nut 14 to the right along the screw rod 24, pushing the disc 8 to the right to press the second limiting cover 9. This makes the second sealing ring 10 and the first sealing ring 7 tightly fit the left and right end faces of the brush cylinder 2, forming a bidirectional seal. At the same time, the cooperation between the limiting square post 12 and the limiting square groove 11 restricts the circumferential rotation of the disc 8 to ensure a stable installation. The installation is now complete.

[0047] When the bristles of the brush cylinder 2 are worn or damaged, use a wrench to rotate the hexagonal nut 14 in the opposite direction, so that it moves to the left along the screw 24 until the hexagonal nut 14 is completely disengaged from the screw 24. Remove the hexagonal nut 14 and the rubber washer, and then move the disc 8 to the left so that the limiting column 12 is pulled out from the limiting groove 11. Remove the second limiting cover 9, and then pull the brush cylinder 2 to the left along the axis of the rotating cylinder 3 so that the limiting strip 5 on the inner wall slides out from the limiting groove 4 of the rotating cylinder 3. The brush cylinder 2 can then be removed as a whole. In this way, the brush cylinder 2 with bristles can be easily replaced, avoiding the need to discard the whole device, effectively reducing material waste and lowering construction costs.

[0048] To adjust the overall length according to the construction needs of different basement heights, hold the round rod 17 and slide it up and down vertically. This will cause the slider 19 to slide synchronously within the groove 18. When the device length is adjusted to a suitable construction height, rotate the anti-slip torsion block. The threaded column 22 will drive the limiting column 23 to move to the left, aligning the limiting column 23 with and inserting it into the corresponding limiting round hole 20 until the limiting column 23 is fully embedded. Then, through the cooperation of the limiting column 23 and the limiting round hole 20, the semi-circular plate 16 and the round rod 17 are locked, ensuring that the length remains unchanged during construction. Since the semi-circular plate 16 has a semi-circular structure, it will prevent the limiting round hole 20 from being blocked during operation, making it easy to align the limiting column 23 with and insert it into the corresponding limiting round hole 20. Thus, the overall length of the device can be flexibly adjusted with the length adjustment mechanism, making it adaptable to the construction needs of different heights of basement walls, ceilings, and narrow spaces, significantly improving ease of use.

[0049] During use, when the bristles of the brush cylinder 2 contact the wall and roll, the rotating cylinder 3 rotates synchronously through the outer rings of multiple bearings. At the same time, the first limiting cover 6 and the second limiting cover 9 rotate through two sealed bearings respectively. Since the two sealed bearings and multiple bearings have low friction characteristics, the rotation of the brush cylinder 2 and the bristles can be ensured to be smooth and unobstructed. Meanwhile, the first sealing ring 7 and the second sealing ring 10 are respectively embedded in the grooves of the first limiting cover 6 and the second limiting cover 9, and tightly abut against the left and right end faces of the brush cylinder 2, effectively preventing paint from seeping into the inner cavity of the brush cylinder 2 from the connection.
