Description

Technical Field

[0001] The utility model relates to the technical field of wall processing, in particular to a painting device for building walls. Background Art

[0002] In construction projects, painting building walls is an important part. Painting can provide a uniform appearance and color for building walls, making them look more beautiful and neat. Different color and texture selections can be used to achieve a specific design style or meet personal aesthetic needs. At the same time, painting can provide additional protection to prevent the wall from being damaged by the external environment.

[0003] In the process of painting building walls, workers often use roller brushes. Conventional roller brushes are mainly composed of a brush rod, a roller and a brush cover. Conventional roller brushes require the brush cover to be dipped into the paint in the bucket, and then the brush cover is aimed at the wall for painting. However, in this process, some paint is likely to drip onto the ground, and the paint needs to be dipped frequently, which not only causes paint waste, but also increases the difficulty of subsequent cleaning of the ground. At the same time, the operation is also more troublesome, and workers often need to bend or squat frequently, which can easily cause fatigue to the body. To this end, we propose a painting device for building walls. Utility Model Content

[0018] Embodiment 1

[0019] See also Figure 1-Figure 4 A painting device for building walls shown in the figure comprises a holding cylinder 6, an edge portion of the outer wall of the holding cylinder 6 is fixedly connected with a splicing tube 7, an outer wall of the splicing tube 7 is rotatably sleeved with a filter cartridge 1 away from the holding cylinder 6, and an end of the splicing tube 7 away from the holding cylinder 6 is fixedly connected with a connecting tube 10, a brush sleeve 2 is fixedly sleeved on the outer wall of the filter cartridge 1, the connecting tube 10 is located on the inner side of the filter cartridge 1, and a plurality of leakage holes 11 are opened in a linear array on the outer wall of the connecting tube 10, an injection tube 3 is fixedly connected to the top of the outer wall of the holding cylinder 6 near the splicing tube 7, a sealing assembly is provided on the inner wall of the injection tube 3, a piston 8 is tightly fitted to the inner wall of the holding cylinder 6, the piston 8 is close to the injection tube 3, and a push rod 9 is fixedly connected to one side wall of the piston 8, and the push rod 9 movably passes through one side wall of the holding cylinder 6.

[0020] See also Figure 1 and Figure 2 In the figure, the end of the push rod 9 away from the piston 8 is fixedly connected to the connecting plate 5.

[0021] See also Figure 4 In the figure, an internal thread 12 is provided on the upper portion of the inner wall of the injection tube 3.

[0022] See also Figure 1 In the figure, an observation plate 4 is fixedly installed through the outer wall of the holding tube 6, and the observation plate 4 is made of glass material; specifically, the observation plate 4 made of glass material is transparent, so that it is convenient to observe the content of paint inside the holding tube 6 and to add paint to the inside of the holding tube 6 in time.

[0023] In this embodiment, first, the paint bucket and the water pump are prepared, and the water inlet end of the water pump and the paint bucket are connected to each other through a pipeline. Then, the connection plate 5 is held and pulled backward, and the connection plate 5 can drive the push rod 9 and the piston 8 to move successively, and the piston 8 will slide backward on the inner wall of the holding tube 6 until the piston 8 is away from the injection tube 3. Then, the water outlet end of the water pump is connected to the injection tube 3 through a pipeline. Since the upper part of the inner wall of the injection tube 3 is provided with an internal thread 12, the pipeline and the injection tube 3 can be fixed together by a threaded connection for easy disassembly and assembly. Then, the water pump is started, so that the water pump can transport the paint to the inside of the holding tube 6, and the paint will enter the connecting tube 10 along the splicing tube 7, and the paint will also drip into the filter cartridge 1 along the leakage hole 11 on the outer wall of the connecting tube 10, and the paint will pass through the hole of the filter cartridge 1 and be adsorbed by the brush cover 2. At the same time, the inside of the holding tube 6 can be filled with paint, and then the pipeline connected to the injection tube 3 is unscrewed. The paint bucket and the water pump are both well-known prior art and will not be described in detail.

[0024] Then you can hold the holding tube 6 and roll the brush cover 2 on the building wall to perform the painting operation. The filter cartridge 1 will rotate on the outer wall of the splicing tube 7. When the paint adsorbed in the brush cover 2 is almost used up, push the connecting plate 5 forward. The connecting plate 5 can drive the push rod 9 and the piston 8 to move forward. The piston 8 will push the paint inside the holding tube 6 and the splicing tube 7 into the connecting tube 10, and the brush cover 2 can continue to apply paint.

[0025] It should be noted that the building wall roller brush can be equipped with some paint before use, and when the brush cover 2 needs to be painted, there is no need to dip it in the paint bucket, so the loading can be easily achieved, which reduces the paint dripping onto the ground as much as possible, and there is no need to dip the paint frequently, thus avoiding waste of paint and increasing the difficulty of subsequent cleaning of the ground. At the same time, it is easy to operate, and the staff does not need to bend or squat frequently, which reduces the workload of the staff.

[0026] Embodiment 2

[0027] See also Figure 4 This embodiment further explains Example 1. The sealing assembly in the figure includes a connecting ring 13, which is fixedly connected to the middle of the inner wall of the injection tube 3, and a conical rubber plug 17 is tightly fitted at the lower edge of the inner ring surface of the connecting ring 13, and an elastic member is connected between the bottom end of the conical rubber plug 17 and the inner wall of the injection tube 3.

[0028] See also Figure 4In the figure, the elastic member includes a U-shaped plate 14, which is fixedly connected to the inner wall of the injection tube 3, and the U-shaped plate 14 is located below the conical rubber plug 17, and a connecting column 15 is slidably inserted through the inner wall of the U-shaped plate 14 corresponding to the center of the conical rubber plug 17, the top of the connecting column 15 is fixedly connected to the bottom end of the conical rubber plug 17, and a spring 16 is slidably sleeved on the outer wall of the connecting column 15, and the spring 16 is fixedly connected between the upper end of the U-shaped plate 14 and the lower end of the conical rubber plug 17.

[0029] In this embodiment, when the paint is injected into the injection pipe 3, since the pipe and the injection pipe 3 are fixed to each other through a threaded connection, as the paint is continuously injected, the conical rubber plug 17 can be pushed downward under the action of water pressure, and the conical rubber plug 17 can drive the connecting column 15 to slide downward in the inner wall of the U-shaped plate 14, and the conical rubber plug 17 can also squeeze the spring 16 connected to the U-shaped plate 14, so that the injection pipe 3 can be automatically opened when adding material.

[0030] After stopping feeding, the water pressure is lost immediately. At this time, under the action of spring 16, conical rubber plug 17 can be reset and tightly fit on the lower edge of the inner ring surface of connecting ring 13 to seal connecting ring 13, thereby preventing paint from leaking along injection pipe 3 when using the roller brush. After stopping feeding, injection pipe 3 can be automatically closed, which brings convenience to the staff.
