[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] The following is combined with Figure 1-8 This application will be described in further detail.

[0027] This application discloses a wall painting device for interior decoration projects. (Refer to...) Figure 1 and Figure 8A wall painting device for interior decoration engineering includes a wall painting device body 1. The wall painting device body 1 includes a holding rod 101. One end of the holding rod 101 is fixedly connected to a first connecting rod 102. One side of the first connecting rod 102 is fixedly connected to a second connecting rod 103. The inner cavity of the second connecting rod 103 is movably connected to a fixed shaft 105 through a bearing. The surface of the fixed shaft 105 is movably connected to a brush cylinder 104. The surface of the brush cylinder 104 is provided with a squeegee mechanism 2. The inner cavity of the holding rod 101 is provided with an extension mechanism 3.

[0028] The wiping mechanism 2 includes a second mounting block 202. The inner cavity of the second mounting block 202 is fixedly connected to the surface of the fixed shaft 105. A support rod 203 is fixedly connected to one side of the second mounting block 202. There are two support rods 203. A wiping ring 206 is movably connected to the surface of the two support rods 203. The inner cavity of the wiping ring 206 is movably connected to the surface of the brush cylinder 104. A first mounting block 201 is movably connected to one side of the two support rods 203.

[0029] Reference Figure 3 A limiting ring 207 is fixedly connected to the surface of the fixed shaft 105. One side of the limiting ring 207 is movably connected to one side of the brush cylinder 104. The position of the brush cylinder 104 is limited by the limiting ring 207 so that the brush cylinder 104 will not shake when it rotates on the surface of the fixed shaft 105.

[0030] Reference Figure 3 The first mounting block 201 has a snap-fit ​​groove 205 on one side. There are two snap-fit ​​grooves 205. The inner cavity of the snap-fit ​​groove 205 snaps into the surface of the support rod 203. By setting the snap-fit ​​groove 205, the support rod 203 can be snapped into the inner cavity of the first mounting block 201, thereby fixing the position of the first mounting block 201.

[0031] Reference Figure 4 and Figure 5The surface of the wiper ring 206 is provided with an installation groove 209. The inner cavity of the installation groove 209 is movably connected to a limiting plate 211. A spring 210 is fixedly connected to one side of the limiting plate 211. There are three springs 210. One end of the spring 210 is fixedly connected to the inner cavity of the installation groove 209. A moving block 208 is fixedly connected to one side of the limiting plate 211. One side of the moving block 208 is movably connected to the surface of the brush cylinder 104. By setting the moving block 208, the limiting plate 211 and the spring 210 to work together, the elastic action of the spring 210 indirectly drives the moving block 208 to make close contact with the surface of the brush cylinder 104, so that the inner cavity of the wiper ring 206 is in close contact with the surface of the brush cylinder 104, thereby wiping water from the brush on the surface of the brush cylinder 104. The position of the moving block 208 is limited by the setting of the limiting plate 211, so that the moving block 208 will not detach from the inner cavity of the wiper ring 206 during movement.

[0032] Reference Figure 4 The surface of the wiper ring 206 is provided with a sliding groove 204. There are two sliding grooves 204. The inner cavity of the sliding groove 204 is movably connected to the surface of the support rod 203. The sliding groove 204 serves as a guide when the wiper ring 206 slides on the surface of the support rod 203.

[0033] Reference Figure 6 and Figure 7 The extension mechanism 3 includes a storage groove 305, which is formed in the inner cavity of the grip rod 101. A threaded rod 301 is movably connected to the inner cavity of the storage groove 305. A handle 302 is fixedly connected to one end of the threaded rod 301. A threaded ring 303 is fixedly connected to the inner cavity of the storage groove 305. The inner cavity of the threaded ring 303 is threadedly connected to the surface of the threaded rod 301. By setting the threaded rod 301 and the threaded ring 303, the threaded rod 301 can rotate threadedly in the inner cavity of the threaded ring 303 and move in the inner cavity of the grip rod 101. The length of the grip rod 101 can be extended for use at higher painting heights.

[0034] Reference Figure 8 A limiting ring 304 is fixedly connected to the surface of the threaded rod 301. The surface of the limiting ring 304 is movably connected to the inner cavity of the receiving groove 305. By setting the limiting ring 304, the threaded rod 301 will not detach from the inner cavity of the receiving groove 305 when it rotates, thus playing a limiting role for the threaded rod 301.

[0035] Working principle: After rinsing the brush cylinder 104 with water, to remove residual water from its surface, first pull the first mounting block 201 to disengage its inner cavity from the support rod 203. Then, slip the wiper ring 206 onto the surfaces of the brush cylinder 104 and support rod 203, sliding it back and forth from left to right to wipe away the water. During the movement of the brush cylinder 104, the elasticity of the spring 210 causes the limiting plate 211 to move, which in turn moves the moving block 208, bringing it into close contact with the surface of the brush cylinder 104. This allows the inner cavity of the wiper ring 206 to contact the surface of the brush cylinder 104. The surface of the brush cylinder 104 is always in close contact. When the water is scraped off, the scraper ring 206 is pulled to disengage from the support rod 203 and the surface of the brush cylinder 104. Then, the first mounting block 201 is snapped onto the surface of the support rod 203. At this point, the water on the surface of the brush cylinder 104 has been scraped off, and the brush cylinder 104 can continue to be used. When it is necessary to paint a wall with a high height, hold the handle 101 and turn the handle 302. The handle 302 drives the threaded rod 301 to rotate. Through the threaded connection between the surface of the threaded rod 301 and the inner cavity of the threaded ring 303, the threaded rod 301 extends out through the inner cavity of the handle 101, thereby increasing the length of the handle 101.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
