Description

Technical Field

[0001] This utility model relates to the field of building construction equipment, and in particular to a building coating waterproofing construction device. Background Technology

[0002] Waterproof coating construction requires a high level of cleanliness of the substrate. Inadequate cleaning can lead to poor adhesion between the coating and the substrate, resulting in blistering. To ensure proper substrate cleaning, a significant amount of manpower is required, slowing down the construction process. To accelerate the construction of waterproof coatings, reduce subsequent maintenance work, and improve the first-time acceptance rate, innovation in substrate cleaning techniques for waterproof coating construction is essential.

[0003] Existing paint rollers have a single function, only capable of applying paint (e.g., patent number CN200710134975.3, a fast paint roller), and cannot perform substrate cleaning before applying paint.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] To address the aforementioned deficiencies, the purpose of this utility model is to provide a building coating waterproofing construction device, which can clean the substrate before coating by replacing the multi-functional roller (replacing the cotton roller with a brush roller) and driving the brush roller to rotate through a drive component, thereby avoiding the "hollowing" phenomenon after coating.

[0006] To achieve the above objectives, this utility model provides a building coating waterproofing construction device, including a handle and a drive shaft rotatably mounted on its output end; the end of the drive shaft is provided with a locking member for positioning a multi-functional roller; the handle is provided with a drive assembly for driving the drive shaft to rotate, the drive assembly including a transmission roller located inside the handle and connected by a universal joint; the drive shaft is fitted with a multi-functional roller; the drive shaft is provided with a positioning groove for rotating and positioning the multi-functional roller.

[0007] According to the building coating waterproofing construction device of this utility model, the handle includes a grip part and a connecting part for connecting the drive shaft and the grip part; both the grip part and the connecting part are provided with cavities.

[0008] According to the building coating waterproofing construction device of this utility model, a rotating motor is installed inside the handle part; multiple transmission rollers connected by universal joints are installed inside the connecting part; the transmission rollers located at the end positions are respectively connected to the output end of the rotating motor and the drive shaft through a gear structure.

[0009] According to the building coating waterproofing construction device of this utility model, the locking member is screwed to the end of the drive shaft.

[0010] According to the building coating waterproofing construction device of this utility model, the multi-functional roller is a brush roller; the multi-functional roller is provided with a protrusion that cooperates with the positioning groove.

[0011] According to the building coating waterproofing construction device of this utility model, the functional roller is a cotton roller.

[0012] This utility model provides a building coating waterproofing construction device, including a handle and a drive shaft rotatably mounted on its output end. The handle contains a drive assembly that drives the drive shaft to rotate. A multi-functional roller, which can be a brush roller or a cotton roller, is fitted over the drive shaft. When cleaning the substrate is required, the brush roller is installed outside the drive shaft, and the drive assembly is activated. The drive assembly further drives the brush roller actively, cleaning dust and impurities on the substrate through the rotating brush roller, thus preventing poor adhesion between the coating and the substrate. This utility model allows for cleaning of the substrate before coating by replacing the multi-functional roller (replacing the cotton roller with a brush roller) and driving the brush roller to rotate through the drive assembly, preventing "hollowing" after coating.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0020] See Figure 1 and Figure 2 This utility model provides a building coating waterproofing construction device, which includes a handle 1 and a drive shaft 2 rotatably installed at its output end; the handle 1 is provided with a drive component to drive the drive shaft 2 to rotate; the drive shaft 2 is fitted with a multi-functional roller 3, which can be a brush roller or a cotton roller; when it is necessary to clean the base layer (such as the wall to be coated), the brush roller is installed outside the drive shaft 2 and the drive component is activated. The drive component further drives the brush roller to actively clean the dust and impurities on the base layer by rotating the brush roller, so as to avoid the phenomenon of poor adhesion between the coating and the base layer.

[0021] See Figure 3 The handle 1 includes a grip portion 11 and a connecting portion 12 for connecting the drive shaft 2 and the grip portion 11; both the grip portion 11 and the connecting portion 12 have internal cavities. A rotary motor 4 is installed inside the grip portion 11; multiple transmission rollers 5 connected by universal joints 8 are provided inside the connecting portion 12; the transmission rollers 5 located at the ends are connected to the output end of the rotary motor 4 and the drive shaft 2 respectively through a gear structure. In this example, the gear structure adopts a right-angle gear structure (or a bevel gear structure). The right-angle gear structure and the universal joint 8 are well-known technical means to those skilled in the art and will not be described in detail here. When the drive shaft 2 is driven to rotate, the rotary motor 4 is started. The rotary motor 4 transmits the rotational force to the transmission rollers 5 through the right-angle gear structure, and further, under the power transmission action of the universal joint 8, the rotational force is further transmitted to the drive shaft 2.

[0022] The drive shaft 2 is equipped with a locking member 6 at its end for positioning the multi-functional roller 3. In this example, the locking member 6 is screwed to the end of the drive shaft 2, thereby locking the multi-functional roller 3 onto the drive shaft 2. When changing the type of multi-functional roller 3, it is only necessary to remove the locking member 6, replace the multi-functional roller 3, and then reinstall the locking member 6.

[0023] See Figure 2 The drive shaft 2 is provided with a positioning groove 21 for rotating and positioning the multifunctional roller 3;

[0024] See Figure 2 and Figure 4When the multi-functional roller 3 uses a brush roller 311, the multi-functional roller 3 is provided with a protrusion 31 that cooperates with the positioning groove 21. Under the action of the cooperation between the protrusion 31 and the positioning groove 21 (during installation, the protrusion 31 will be inserted into the positioning groove 21), the multi-functional roller 3 will not rotate relative to the drive shaft 2 after installation, further enabling the drive shaft 2 to transmit the rotation effect to the multi-functional roller 3. The rotating brush roller cleans dust and impurities on the base layer.

[0025] join Figure 5 When the multi-functional roller 3 uses a cotton roller 312 (used to pick up paint and roll it onto the substrate during coating work), the cotton roller does not have a protrusion 31 structure inside. In other words, the cotton roller can rotate freely on the drive shaft 2. This increases the rotational flexibility of the cotton roller and facilitates coating work.

[0026] In summary, this utility model provides a building coating waterproofing construction device, including a handle and a drive shaft rotatably mounted on its output end; the handle contains a drive assembly that drives the drive shaft to rotate; the drive shaft is fitted with a multi-functional roller, which can be a brush roller or a cotton roller; when it is necessary to clean the substrate, the brush roller is installed outside the drive shaft, and the drive assembly is activated. The drive assembly further drives the brush roller to rotate actively, cleaning dust and impurities on the substrate through the rotating brush roller, thus preventing the coating from not adhering firmly to the substrate. This utility model can clean the substrate before coating by replacing the multi-functional roller (replacing the cotton roller with a brush roller) and driving the brush roller to rotate through the drive assembly, thus avoiding the "hollow" phenomenon after coating.

[0027] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
