[0002] Building decoration is mainly to protect the main structure of the building, improve the use function of the building and beautify the building. It uses decorative materials or ornaments to carry out various treatment processes on the internal and external surfaces and spaces of the building. In the process of building decoration, wall painting is an indispensable operation step. When painting the wall, latex paint or other wall paint is needed to be rolled on the wall, and a wall painting device is needed to operate during the rolling process.

[0003] In view of this, Chinese Patent No. CN215594769U proposes a wall brushing device for building decoration; the utility model adds a threaded rod with a threaded connection in the inner cavity of the handle, which can be adjusted by adjusting the distance between the connecting section of the threaded rod and the handle to achieve the purpose of lifting and lowering, and the paint is infiltrated into the round roller through the evenly distributed penetration holes on the surface of the isolation plate. However, when the existing wall brushing device rolls the wall paint, the roller brush is cylindrical, and a certain area of ​​dead angle will be generated for the connection area between the gypsum line on the top of the wall and the wall. In this dead angle area, the staff generally stand on the ladder and use the brush manually to paint, which is very troublesome to operate and increases the risk of the staff climbing to work. Therefore, the present design scheme improves a wall brushing device for building decoration. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the overall concept of the utility model, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0021] The examples are as follows:

[0022] The utility model provides Figure 1-4 The wall brushing device for building decoration shown in the figure comprises a roller brush 1, a support mechanism 2 installed outside the roller brush 1, and a telescopic mechanism 3 installed at the tail of the support mechanism 2;

[0023] The supporting mechanism 2 includes a supporting frame 201 rotatably sleeved on the outer wall of the roller brush 1, a first connecting frame 202 is rotatably provided on one side of the supporting frame 201, a second connecting frame 203 is rotatably provided on one end of the first connecting frame 202, a connecting rod 204 is rotatably provided between the outer walls of the first connecting frame 202 and the second connecting frame 203, a first electric telescopic rod 205 is rotatably installed on both sides of the outer wall of the connecting rod 204, a limiting slide groove 206 is provided on one side of the first connecting frame 202, a slider 207 is slidably provided on the inner wall of the limiting slide groove 206, a connecting strip 208 is rotatably provided on the inner wall of the slider 207, a second electric telescopic rod 209 is fixedly provided on one side of the inner wall of the limiting slide groove 206, and when the first electric telescopic rod 205 is contracted, the connecting rod 204 is folded, and when it is folded to the maximum, the first connecting frame 202 and the second connecting frame 203 are just in a 90-degree state, and can remain stable.

[0024] The output end of the second electric telescopic rod 209 is fixedly connected to one side of the slider 207, and one end of the connecting bar 208 is rotatably connected to one side of the support frame 201. Since the connecting bar 208 is rotatably connected between the slider 207 and the support frame 201, when the second electric telescopic rod 209 is retracted, the connecting bar 208 rotates therein and the length is limited so that the support frame 201 rotates on the first connecting frame 202, and the maximum rotation angle with the first connecting frame 202 is 90 degrees;

[0025] Furthermore, the telescopic mechanism 3 includes an extension rod 301 fixed to the tail of the second connecting frame 203, and the outer wall of the extension rod 301 is provided with a grip rod 302, and when the staff paints the wall, they mainly operate by holding the grip rod 302;

[0026] Furthermore, a connection groove 303 is formed on one side of the outer wall of the handle 302 , and a fixing bolt 304 is inserted into the inner wall of the connection groove 303 .

[0027] A screw hole 305 is provided at the edge of one side of the extension rod 301, and the outer wall of one end of the fixing bolt 304 passes through the inner wall of the connecting groove 303 and is threadedly connected to the inner wall of the screw hole 305. When the length of the wall brushing device is adjusted, the extension rod 301 is mainly inserted into the inside of the gripping rod 302, and the fixing bolt 304 is turned so that it is threadedly connected in the screw hole 305 and squeezed on the outer edge of the connecting groove 303, so that the gripping rod 302 and the extension rod 301 can be fixed.

[0028] Working principle: When using the wall painting device for building decoration in the present design, first, it is necessary to dip the roller brush 1 into paint and paint on the wall. When brushing to the dead corner near the plaster line, start the first electric telescopic rod 205 to make it telescope between the connecting rods 204, and then fold the connecting rods 204. While folding, the first connecting frame 202 rotates on the second connecting frame 203, and then the support frame 201 and the roller brush 1 thereon are rotated to form a ninety-degree angle with the second connecting frame 203. The staff can operate the grip 302 to move the roller brush 1 left and right at the bottom, so that the edge of the roller brush 1 contacts the edge of the plaster line and the originally horizontal and non-conforming part is moved. At the same time, when painting a narrow area, the second electric telescopic rod 209 is started to make the connecting strip 208 slide in the limiting slide groove 206 through the slider 207, and then the support frame 201 is rotated to form a ninety-degree angle with the first connecting frame 202. The staff does not need to tilt the wall painting device, and can paint by pushing it in the vertical direction, making it more convenient for the staff to paint the wall. At the same time, according to the height of the wall, the gripping rod 302 is slid on the extension rod 301 and then the fixing bolt 304 is screwed in the connecting groove 303 to make it threadedly connected with the screw hole 305 to fix the adjusted length of the gripping rod 302.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0030] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
