Technical Field

[0001] The utility model relates to the technical field of roller brushes, in particular to a roller brush for building construction. Background Technique

[0002] With the acceleration of the urbanization process, the urbanization rate in China will increase to more than 76% in the future, and the contribution rate of cities to the entire national economy will reach more than 95%. The development of urban agglomerations, city clusters, urban belts and central cities indicates the rapid take-off of China's urbanization process and also brings a broader market for the construction industry. In the large-area paint rolling of daily building decoration projects, a roller brush is often used. A roller brush, also known as a roller, is a tool for large-area paint rolling.

[0003] For common roller brushes for building construction, the rollers are mostly fixedly installed, which is very inconvenient to disassemble, and it is difficult to scrape off the residual paint on the surface of the roller during cleaning, which is not convenient for subsequent cleaning. Therefore, a roller brush for building construction is proposed to solve the above problems. Content of the Utility Model

One end of the connecting plate is connected to a support plate. A sleeve is arranged at the center of the support plate. The sleeve is sleeved on the surface of the support frame and can rotate;

[0006] An extrusion strip is installed on the inner wall of the collar. A convex block is arranged on one side of the extrusion strip. There are multiple groups of the convex blocks. The convex blocks are fixedly installed on the inner wall of the collar.

[0007] Further, a roller is arranged inside the rolling brush. The rolling brush can rotate on the surface of the roller. A cross bar is arranged inside the roller. A nut is arranged on the side surface of one end of the cross bar. The nut meshes with a tooth.

[0008] Furthermore, baffles are connected to both ends of the roller. The baffles are arranged outside both ends of the rolling brush.

[0009] Furthermore, a hinge block is installed on the surface of one end of the support frame. A knob is arranged on one side of the hinge block. A screw rod is connected to one side of the knob. One end of the screw rod penetrates through the hinge block and extends to the outside.

[0010] Furthermore, the upper end of the connecting rod is fixedly connected to the lower surface of the support frame. A grip rod is arranged inside the connecting rod. The grip rod can rotate on the surface of the connecting rod. The surface of the lower end of the connecting rod is provided with first teeth, and the inner wall of the grip rod is provided with second teeth. The first teeth and the second teeth are engaged with each other.

[0011] Furthermore, an installation block is connected to the surface of the other end of the support frame. A clamping ring is connected to the upper surface of the installation block. The clamping ring is made of steel sheet and has elasticity. A connecting column is connected to the surface of the other end of the cross bar. The connecting column is stuck inside the clamping ring.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By setting the support plate to drive the sleeve to slide on the surface of the support frame, and at the same time drive the connecting plate and the collar to move, the collar is sleeved on the outside of the rolling brush. By installing bumps and extrusion strips on the inner wall of the collar, and by moving the collar on the surface of the rolling brush, the residual paint on the surface of the rolling brush can be scraped off. Then the rolling brush is put into clean water, and by continuously pushing and pulling the collar to drive the bumps to rub on the surface of the rolling brush, the cleaning effect can be achieved, greatly improving the cleaning efficiency of the rolling brush.

[0014] 2. By sleeving the rolling brush and the roller on the outside of the cross bar, then screwing the nut tightly on the teeth to fix the roller, and then flipping the cross bar to one side to stick the connecting column connected to one end of it inside the clamping ring, and then rotating the knob to drive the screw rod to rotate to lock the connection between the hinge block and the cross bar, the installation of the rolling brush can be completed, avoiding the problem that the traditional roller is mostly fixedly installed and the disassembly is very inconvenient.

[0015] 3. By setting the grip rod to drive the second teeth to rotate, making them misaligned with the first teeth and then pulling the grip rod downward and stretching the length according to the need, and then rotating the grip rod to make the second teeth overlap with the first teeth, the length of the grip rod can be adjusted conveniently.
