DETAILED DESCRIPTION

[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] like Figure 1-Figure 3 As shown, a paint brush for high-viscosity paint includes a brush housing assembly 1, a brush handle 3 and a brush head assembly 4. The brush housing assembly 1 includes a brush housing mainboard 101, a convex plate 102 and a T-shaped slide 103, and the cross-section of the brush housing mainboard 101 is an arc-shaped structure. The convex plate 102 is fixed in the middle of the outside of the brush housing mainboard 101, and the convex plate 102 is provided with a T-shaped slide 103 inside. The brush housing assembly 1 also includes a connecting plate 104 and a connecting bolt 105. The upper and lower sides of the T-shaped slide 103 are slidably installed with the connecting plate 104 through a slider, and the middle of one side of the connecting plate 104 is penetrated by the connecting bolt 105. The brush housing assembly 1 also includes a connecting plate 104 and a connecting bolt 105. It includes a side frame plate 106 and a connecting sleeve 107. The side frame plate 106 is fixed to the other side of the connecting plate 104, and the side frame plate 106 is a semicircular structure, and the connecting sleeve 107 is fixed at the center of the side frame plate 106. The brush housing assembly 1 also includes a flexible connecting plate 108. The flexible connecting plate 108 is connected between the side frame plate 106 and the brush housing main board 101, and the structure of the flexible connecting plate 108 is the same as that of half a bellows. The brush housing assembly 1 also includes a threaded barrel 109 and a locking bolt 110. The threaded barrel 109 is embedded and fixed in the middle of the side frame plate 106, and the locking bolt 110 is installed inside the threaded barrel 109.

[0021] The brush housing main board 101 cooperates with the connecting plate 104, the side frame plate 106 and the flexible connecting plate 108 to form a whole brush housing, so as to collect the paint liquid dripping from the brush head assembly 4. The locking bolt 110 passes through the threaded tube 109 to facilitate the bolt connection assembly between the brush head seat 401 and the brush housing assembly 1, so as to facilitate the replacement and disassembly of different brush head assemblies 4. The position of the connecting plate 104 can be adjusted by sliding, so as to facilitate the adjustment of the position of the side frame plate 106. The flexible connecting plate 108 between the side frame plate 106 and the brush housing main board 101 can be contracted and expanded to cooperate with the position adjustment of the side frame plate 106 to change the length of the brush housing assembly 1, and is suitable for brush head assemblies 4 of different lengths.

[0022] like Figure 2 and Figure 3As shown, a connecting frame 2 is fixed to the outside of the brush shell mainboard 101, and a brush handle 3 is installed on the outside of the connecting frame 2. The brush handle 3 is a telescopic rod structure, and the surface of the brush handle 3 is provided with a non-slip rubber layer. A brush head assembly 4 is installed on the inside of the brush shell assembly 1, and the brush head assembly 4 includes a brush head seat 401 and bristles 402. Bristles 402 are fixed to the outside of the brush head seat 401, and the bristles 402 are specifically plastic chemical fiber bristles, and the surface of the bristles 402 has a spiral texture structure; the brush handle 3 is a telescopic rod structure, which is convenient for adjusting the total length of the brush handle 3. The bristles 402 are plastic chemical fiber bristles, which can reduce the production cost compared to pig bristles. When the plastic chemical fiber filaments are produced, a spiral roller is installed on the extrusion head of the chemical fiber filaments. The roller squeezes the chemical fiber filaments to form a spiral texture on the surface of the bristles 402, further increasing the contact area between the bristles 402 and the high-viscosity paint to achieve the purpose of increasing the adhesion of the paint, thereby making the paint brush structure compact and reasonable, and at the same time low in manufacturing cost. It can also increase the paint storage capacity of the bristles 402, reduce the frequency of dipping paint, and further improve the work efficiency of workers.

[0023] In summary, if Figure 1-Figure 3 As shown, the paint brush for high-viscosity paint has a telescopic rod structure during use, which can adjust the total length of the brush handle 3. The bristles 402 used for the paint brush are plastic chemical fiber bristles, which can reduce the production cost compared to boar bristles. When the plastic chemical fiber filaments are produced, a spiral roller is installed on the extrusion head of the chemical fiber filaments. The roller squeezes the chemical fiber filaments to form a spiral texture on the surface of the bristles 402, further increasing the contact area between the bristles 402 and the high-viscosity paint to achieve the purpose of increasing the adhesion of the paint; when the brush head assembly 4 needs to be disassembled, the locking bolt 110 can be removed to facilitate the removal of the brush head seat 401 and the bristles 402, and vice versa, the installation can be carried out in the same way, and during use, the position of the side frame plate 106 can be slid and adjusted and fixed by the connecting bolt 105. At this time, the flexible connecting plate 108 can be contracted and expanded to cooperate with the position adjustment of the side frame plate 106 to change the length of the brush shell assembly 1, so that the structure is also suitable for brush head assemblies 4 of different lengths, thus completing the use process of the paint brush for high-viscosity paint.
