Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to an anti-drip paint roller brush device. Background Art

[0002] As a key building material, coatings play a vital role in waterproofing various building structures. They effectively prevent water penetration and protect building structures from water erosion, thereby extending the service life of the building. During the application of waterproof coatings, roller brushes are the primary tool, ensuring that the coating adheres evenly and efficiently to the treated surface. The roller brushes are particularly effective on flat surfaces.

[0003] However, despite the wide variety of paint rollers available on the market, traditional rollers cannot adjust the brush height, making it difficult to apply paint to exterior walls of varying heights. This increases the difficulty of applying paint and reduces construction efficiency. Furthermore, during the application process, paint may drip onto the ground due to improper operation or design flaws. This not only wastes paint but also negatively impacts the sanitation of the construction site. After the application is complete, construction workers must perform additional cleaning, further increasing construction costs and time. Utility Model Content

[0057] Further, the rolling brush device 3 comprises mounting assemblies, a brushing roller 31 and a receiving member 32, the receiving member 32 is located directly below the brushing roller 31, and the top of the receiving member 32 is inwardly recessed, so that when the brushing roller 31 brushes the paint, any dripping paint can be received by the receiving member 32, thereby avoiding the situation that the paint drips to the ground.

[0058] Meanwhile, the brushing roller 31 is rotationally mounted on the front end of the opposite faces of the two groups of mounting assemblies, and the rotation axis of the brushing roller 31 extends left and right, and the receiving member 32 is mounted on the front end of the opposite faces of the two groups of mounting assemblies, the above design ensures the close cooperation between the brushing roller 31 and the receiving member 32, so that the paint is not easy to drip during the brushing process.

[0059] Further, the number of the mounting assemblies is at least two groups, and the two groups of mounting assemblies are symmetrically mounted on the left and right sides of the front end of the position adjusting mechanism 2, which not only helps to improve the stability of the rolling brush device, but also enables the brushing roller 31 to more uniformly brush the paint, thereby reducing the possibility of paint dripping.

[0065] The mounting assembly comprises a mounting arm 33, a pull rod 34, an elastic member 35 and a guide rod 36, so that the receiving member 32 is mounted on the mounting arm 33 through the pull rod 34, the elastic member 35 and the guide rod 36, ensuring the firmness of the installation of the receiving member 32. At the same time, the pull rod 34 and the guide rod 36 are relatively stationary, and the pull rod 34 and the guide rod 36 are both moved left and right relative to the mounting arm 33, so that the installation position of the receiving member 32 can be fine-tuned, and the receiving member 32 is always located directly below the brush roller 31, further reducing the possibility of paint dripping.

[0066] Further, the receiving member 32 comprises a receiving box 321 and at least two connecting arms 322, the receiving box 321 is located directly below the brush roller 31, and the top of the receiving box 321 is inwardly recessed; one of the connecting arms 322 is sleeved around the outside of the guide rod 36 of one of the mounting assemblies in the front-rear direction, and the other connecting arm 322 is sleeved around the outside of the guide rod 36 of the other mounting assembly in the front-rear direction;

In addition, when the paint receiving box 321 accumulates too much paint or impurities, and the paint receiving member 32 needs to be disassembled for cleaning the paint or impurities in the paint receiving box 321, the outer end of the pull rod 34 is simply pulled outward, the vertical mounting portion of the pull rod 34 compresses the elastic member 35, the elastic member 35 deforms to provide a moving space for the horizontal connecting portion of the pull rod 34 to move outward, so that the horizontal connecting portion of the pull rod 34 is separated from the mounting slot, and the paint receiving member 32 can be disassembled from the mounting arm 33. In addition, since the paint receiving member 32 can be disassembled from the mounting arm 33, a new paint receiving member 32 can be replaced to effectively collect the paint dropped by the paint roller 31, and the possibility of paint dripping can be further avoided.
