Description

Technical Field

[0001] This application relates to the field of spraying apparatus, and more particularly to a waterproof coating spraying apparatus for building waterproofing construction. Background Technology

[0002] Building waterproofing construction, through the scientific selection of materials and standardized processes, forms a continuous and sealed waterproof layer that effectively blocks water penetration, protects the building structure from erosion, extends the building's service life, and prevents problems such as mold and equipment damage caused by indoor leaks. It ensures residential safety and comfort and is a key measure to ensure the integrity and durability of building functions.

[0003] Regarding the aforementioned technologies, the inventors believe that in current building waterproofing construction, waterproof coating spraying devices are mostly used to spray waterproof coatings. However, in actual use, after the waterproof coating is sprayed, air bubbles are easily found between the waterproof coating and the wall surface. When these air bubbles burst, they form small bowl-shaped defects, resulting in a thinner coating and uneven spraying thickness. This can lead to cracking of the coating and affect the spraying effect of the waterproof coating. Utility Model Content

[0009] Optionally, the positioning component includes a top block sleeved on the outside of the spray gun body. An elastic element is provided on the side of the top block opposite to the connecting sleeve. One end of the elastic element is fixed to the spray gun body, and the other end of the elastic element is fixed to the top block. A limiting engagement component is provided between the top block and the connecting sleeve. When the elastic element is in a compressed state, the limiting engagement component is relatively disengaged, and the connecting sleeve rotates. When the elastic element is in a free state, the limiting engagement component is relatively engaged, restricting the rotation of the connecting sleeve.

[0010] Optionally, the limiting engagement component includes a first locking tooth fixed on the top block, and a second locking tooth is also provided on one side of the connecting sleeve opposite to the first locking tooth. Multiple first locking teeth are equidistantly arranged along the circumference of the top block, and multiple second locking teeth are equidistantly arranged along the circumference of the connecting sleeve. The second locking teeth are located between two opposite first locking teeth, and multiple second locking teeth cooperate with multiple first locking teeth.

[0011] Optionally, a positioning block is fixedly connected to the spray gun body, and a first inner cavity is opened in the rotating sleeve relative to the positioning block.

[0015] Optionally, the spray gun body is fixedly connected to a support ring between the top block and the ring block, the elastic element abuts against the support ring, the support ring has a through hole relative to the pull rod, and the pull rod slides through the through hole.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. By setting a connecting sleeve, the position of the oil surface roller can be adjusted by rotating the connecting sleeve and the connecting frame. The positioning component positions the connecting sleeve to stabilize the oil surface roller in the required position. When the spray gun body is used to spray waterproof coating, the movement of the spray gun body causes the oil surface roller to roll over the sprayed area, thereby effectively avoiding bubbles and other issues. At the same time, it makes the waterproof coating more evenly distributed and reduces the risk of cracking of the waterproof coating.

[0018] 2. By setting a positioning component, when rotating the connecting sleeve, the top block slides on the surface of the spray gun body, so that the first locking tooth and the second locking tooth are separated. Then the connecting sleeve and the connecting frame can be rotated. After the oil surface roller is rotated to the desired position, the top block is released. The spring drives the top block to reset, so that the first locking tooth engages with the second locking tooth again. The position of the top block is stabilized by the limit block, so that the top block plays a positioning role for the connecting sleeve, so that the oil surface roller is kept in the desired position.

[0024] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0026] Building waterproofing construction, through the scientific selection of materials and standardized processes, forms a continuous and sealed waterproof layer that effectively blocks water penetration, protects the building structure from erosion, extends the building's service life, and prevents problems such as mold and equipment damage caused by indoor leaks. It ensures residential safety and comfort and is a key measure to ensure the integrity and durability of building functions.

[0027] Regarding the aforementioned technologies, the inventors believe that in current building waterproofing construction, waterproof coating spraying devices are mostly used to spray waterproof coatings. However, in actual use, after the waterproof coating is sprayed, air bubbles are easily found between the waterproof coating and the wall surface. When these air bubbles burst, they form small bowl-shaped defects, resulting in a thinner coating and uneven spraying thickness. This can lead to cracking of the coating and affect the spraying effect of the waterproof coating.

[0028] In order to reduce the uneven spraying caused by air bubbles between the waterproof coating and the wall surface after spraying and to improve the spraying effect, this application provides a waterproof coating spraying device for building waterproofing construction.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a waterproof coating spraying device for building waterproofing construction. Referring to the figures, the waterproof coating spraying device for building waterproofing construction includes a spray gun body 1, and a nozzle for spraying is provided at the end of the spray gun body 1.

[0031] A connecting sleeve 2 is rotatably fitted on the surface of the spray gun body 1. A connecting frame 3 is fixedly connected to the surface of the connecting sleeve 2. An oil surface roller 4 is rotatably mounted on the connecting frame 3. A connecting component 31 is provided at one end of the connecting frame 3. The connecting component 31 is used in conjunction with the oil surface roller 4. A positioning component 5 is provided on the surface of the spray gun body 1. The positioning component 5 is used in conjunction with the connecting sleeve 2.

[0032] The outer wall of the oil roller 4 is located on the side of the nozzle away from the spray gun body 1, so that when the oil roller 4 rolls over the construction position, the nozzle will not come into contact with the construction position.

[0033] The positioning component 5 includes a spring 51, which is coaxially arranged with the spray gun body 1. The spring 51 is slidably sleeved on the surface of the spray gun body 1. One end of the spring 51 is fixedly connected to the surface of the spray gun body 1, and the other end of the spring 51 is fixedly connected to a top block 52, which is slidably sleeved on the surface of the spray gun body 1. In a specific embodiment, a support ring is also coaxially fixedly connected to the side wall of the spray gun body 1. One end of the spring 51 is fixed to the support ring, and the other end of the spring 51 is fixed to the top block 52.

[0034] A plurality of first locking teeth 53 are fixedly installed on one side of the top block 52 near the connecting sleeve 2, and a plurality of second locking teeth 54 are fixedly installed on one side of the connecting sleeve 2 near the top block 52. The plurality of first locking teeth 53 are equidistantly arranged along the circumferential direction of the top block 52, and the plurality of second locking teeth 54 are equidistantly arranged along the circumferential direction of the connecting sleeve 2, and the second locking teeth 54 are located in the gap formed between two adjacent first locking teeth 53. The plurality of second locking teeth 54 are used in conjunction with the plurality of first locking teeth 53.

[0035] When spraying waterproof coating using the spray gun body 1, adjust the position of the oil surface roller 4 according to the spraying direction, pull the top block 52 to separate the first locking tooth 53 from the second locking tooth 54, and then rotate the connecting sleeve 2 and the connecting frame 3 to adjust the position of the oil surface roller 4. After adjusting the oil surface roller 4 to the required position, release the top block 52 so that the spring 51 drives the top block 52 to reset. Through the reset of the top block 52, the first locking tooth 53 and the second locking tooth 54 are engaged, thereby positioning the connecting sleeve 2 to keep the oil surface roller 4 in the required position.

[0036] Furthermore, during the spraying process, the oil roller 4 rolls the sprayed area to effectively avoid bubbles and other issues, while also making the waterproof coating more evenly distributed and reducing the risk of cracking.

[0037] A positioning block 21 is fixedly installed on the surface of the spray gun body 1. The rotating sleeve has a first inner cavity, which is a cavity adapted to the positioning block 21. The positioning block 21 is located inside the first inner cavity and is rotatably sleeved inside the connecting sleeve 2. By installing the positioning block 21 on the surface of the spray gun body 1, the position of the connecting sleeve 2 is stabilized by the positioning block 21, so as to prevent the connecting sleeve 2 from sliding laterally on the surface of the spray gun body 1 and affecting the position of the connecting frame 3 and the oil roller 4.

[0038] A limiting block 5201 is fixedly installed on the surface of the spray gun body 1. The limiting block 5201 is arranged along the axial direction of the spray gun body 1. The inner sidewall of the top block 52 has a second inner cavity relative to the limiting block 5201. The second inner cavity is adapted to the shape of the limiting block 5201, and the limiting block 5201 is located inside the second inner cavity. The inner cavity of the top block 52 is slidably connected to the surface of the limiting block 5201.

[0039] By setting a limiting block 5201 on the surface of the spray gun body 1, the position of the top block 52 is stabilized by the limiting block 5201. While allowing the top block 52 to slide on the surface of the spray gun body 1, the top block 52 is prevented from rotating, so that the top block 52 can play a positioning and supporting role for the connecting sleeve 2.

[0040] A pull rod 55 is fixedly connected to the surface of the top block 52. One end of the pull rod 55 is fixedly connected to a ring block 56. The ring block 56 is slidably sleeved on the surface of the spray gun body 1. A slider 5601 is fixedly installed on the inner side wall of the ring block 56. A groove 5602 is opened on the surface of the spray gun body 1. The slider 5601 is slidably connected inside the groove 5602.

[0041] By pulling the ring block 56 to move, and stabilizing the position of the ring block 56 through the slider 5601 and the slide groove 5602, the ring block 56 drives the pull rod 55 to move, thereby causing the pull rod 55 to drive the top block 52 to move, so as to adjust the position of the top block 52.

[0042] In a specific embodiment, a through hole is provided at the position of the support ring relative to the pull rod 55. The through hole completely penetrates the side wall of the support ring, and the pull rod 55 passes through the inside of the through hole and is slidably connected to the support ring.

[0043] The connecting assembly 31 includes a connecting rod 3101 and a connecting block 3102. The connecting rod 3101 is rotatably connected inside the connecting frame 3, and the connecting block 3102 cooperates with the connecting rod 3101. The oil roller 4 is rotatably sleeved on the surface of the connecting rod 3101. Support plates 3103 are fixedly installed on the surfaces of both the connecting frame 3 and the connecting block 3102. A bolt 3104 passes through one side of the support plate 3103. The surface of the bolt 3104 is slidably connected to the inner cavity of the support plate 3103. A nut 3105 is threaded onto one end of the bolt 3104, and the surface of the nut 3105 abuts against one side of one of the support plates 3103.

[0044] When it is necessary to replace the oil surface roller 4, separate the nut 3105 from the bolt 3104, then separate the connecting block 3102 from the connecting frame 3, and then remove the oil surface roller 4 and the connecting rod 3101 from the connecting frame 3 to replace the oil surface roller 4. After the new oil surface roller 4 is fitted onto the surface of the connecting rod 3101, insert the connecting rod 3101 into the interior of the connecting frame 3, and align the connecting block 3102 with the connecting frame 3. Use bolts 3104 and nuts 3105 to align several support plates 3103 to fix the position of the connecting block 3102. Thus, the connecting rod 3101 is fixed in the connecting frame 3 by the connecting block 3102, thereby completing the replacement of the oil surface roller 4.

[0045] The implementation principle of the waterproof coating spraying device for building waterproofing construction in this embodiment is as follows: When spraying waterproof coating using the spray gun body 1, the position of the oil surface roller 4 is adjusted according to the spraying direction. The ring block 56 is pulled, and the position of the ring block 56 is stabilized by the slider 5601 and the groove 5602, so that the ring block 56 drives the top block 52 to move through the screw, so that the first locking tooth 53 separates from the second locking tooth 54. Then, the connecting sleeve 2 and the connecting frame 3 are rotated, and the position of the connecting sleeve 2 is stabilized by the positioning block 21 to prevent the connecting sleeve 2 and the connecting frame 3 from lateral displacement, so as to adjust the position of the oil surface roller 4. After the oil surface roller 4 is adjusted to the required position, the ring block 56 is released, so that the spring 51 drives the top block 52 to reset, and the position of the top block 52 is stabilized by the limit block 5201, so that the first locking tooth 53 engages with the second locking tooth 54, thereby positioning the connecting sleeve 2 through the top block 52 to keep the oil surface roller 4 in place. The required position is determined during the spraying process. The oil roller 4 rolls over the sprayed area to effectively avoid bubbles and ensures a more uniform distribution of the waterproof coating, reducing the risk of cracking. When the oil roller 4 needs to be replaced, the nut 3105 is separated from the bolt 3104, and then the connecting block 3102 is separated from the connecting frame 3. The oil roller 4 and connecting rod 3101 are then removed from the connecting frame 3 to replace the oil roller 4. After the new oil roller 4 is placed on the surface of the connecting rod 3101, the connecting rod 3101 is inserted into the interior of the connecting frame 3, and the connecting block 3102 is connected to the connecting frame 3. Several support plates 3103 are then connected using bolts 3104 and nuts 3105 to fix the position of the connecting block 3102. The connecting rod 3101 is then fixed in the connecting frame 3 by the connecting block 3102, thus completing the replacement of the oil roller 4.
