On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0037] Example

[0038] The present embodiment provides a coating brush head 100 having three roller brushes, and the angles of the roller brushes on both sides relative to the roller brush in the middle are adjustable, so that the contact area with the surface to be coated is high and the coating brush head 100 can be adapted to the coating of the outer walls of pipes of different sizes.

[0039] like Figure 1-2 As shown, a brush head 100:

[0040] It includes a middle rod 110 and two adjustment rods 130;

[0041] The two ends of the intermediate rod 110 are respectively hinged to the middle parts of the two adjustment rods 130;

[0042] A first roller brush 120 is installed in the middle of the intermediate rod 110;

[0043] One end of the adjusting rod 130 is a working end, and the other end is an adjusting end;

[0044] A second roller brush 140 is installed at the working end of the adjustment rod 130;

[0045] The adjustment ends of the two adjustment rods 130 are connected via an adjustment mechanism 200, and the adjustment mechanism 200 changes the angle between the adjustment rods 130 and the middle rod 110 by adjusting the distance between the adjustment ends of the two adjustment rods 130;

[0046] The angle between the adjusting rod 130 and the intermediate rod 110 is 90-180 degrees;

[0047] The first roller brush 120 is installed in the middle of the middle rod 110 of the painting brush head 100, and the second roller brush 140 is installed at the working end of the adjustment rod 130. By setting three roller brushes, the contact area with the surface to be painted can be increased, which can significantly improve the efficiency of the painting operation. In order to increase the contact area with the surface to be painted, when used for painting the outer wall of the pipeline, it is necessary to adjust the angle between the adjustment ends of the two adjustment rods 130 according to the size of the pipeline through the adjustment mechanism 200 to adjust the angle between the adjustment rod 130 and the middle rod 110 to an obtuse angle that matches the size of the pipeline; when used for flat painting, the adjustment mechanism 200 is required to adjust the middle rod 110 and the adjustment rod 130 to a parallel state.

[0048] In this embodiment, the adjustment mechanism 200 includes an adjustment sleeve 210 and two screws 220;

[0049] The adjusting sleeve 210 has threads with opposite rotation directions at both ends thereof;

[0050] The two screw rods 220 have threads with the same rotation direction, and the two screw rods 220 are respectively installed at two ends of the adjustment sleeve 210;

[0051] The inner end of the screw rod 220 is threadably matched with the adjusting sleeve 210 , and the outer end of the screw rod 220 is hinged to the adjusting end of the adjusting rod 130 on the same side.

[0052] It should be noted that the angle between the adjustment rod 130 and the middle rod 110 is negatively correlated with the distance between the adjustment ends of the two adjustment rods 130 ;

[0053] Specific:

[0054] When the adjusting sleeve 210 is screwed forward, the two screws 220 move toward each other, the distance between the adjusting ends of the two adjusting rods 130 decreases, and the angle between the adjusting rod 130 and the middle rod 110 increases;

[0055] When the adjusting sleeve 210 is screwed in the reverse direction, the two screw rods 220 move in opposite directions, the distance between the adjusting ends of the two adjusting rods 130 decreases, and the angle between the adjusting rod 130 and the middle rod 110 decreases.

[0056] In this embodiment, the outer surface of the adjusting sleeve 210 is provided with textures for increasing friction, so as to facilitate screwing the adjusting sleeve 210 .

[0057] In this embodiment, in order to avoid interference between the adjustment sleeve 210 and the first roller brush 120 and ensure that the angle between the adjustment rod 130 and the intermediate rod 110 can be adjusted to 180 degrees, an avoidance design is required;

[0058] Specifically: the adjustment sleeve 210 is arranged horizontally; the adjustment end of the adjustment rod 130 is provided with an extension portion extending upward or downward; the end of the extension portion is hinged to the outer end of the screw rod 220; after installation, the extension portion causes the joint sleeve to be located above or below the first roller brush 120 to avoid interference between the adjustment sleeve 210 and the first roller brush 120.

[0059] In this embodiment, the intermediate rod 110 is hinged to the adjusting rod 130 via a pin shaft, and the adjusting rod 130 is hinged to the adjusting mechanism 200 via a pin shaft.

[0060] In this embodiment, the intermediate rod 110 is installed on the adapter frame 300, and the adapter frame 300 has a connector 310 for connecting to the handle 400. The connector 310 allows the paint brush head 100 to be externally connected to the handle 400 to facilitate the operation of the paint brush head 100.

[0061] In order to facilitate driving the painting brush head 100 to perform painting operations, this embodiment further provides a painting brush tool, which includes a handle 400 and the above-mentioned painting brush head 100 ; the painting brush head 100 is connected to the handle 400 via a connecting head 310 .

[0062] like Figure 3 As shown, in one embodiment, the painting tool is suitable for painting flat surfaces and arc surfaces, one brush head 100 is provided, one handle 400 is provided, and the upper end of the handle 400 is hinged to the connecting head 310 via bolts. When in use, the angle between the brush head 100 and the handle 400 can be adjusted by loosening the bolts.

[0063] like Figure 4 As shown, in another embodiment, the painting tool is suitable for painting pipes, and two painting brush heads 100 are provided, and the handle 400 includes two rod bodies 410 cross-hinged in the middle, and the working end of the rod body 410 is fixedly connected to the connecting head 310 of the painting brush head 100, and the operating end of the rod body 410 is provided with an operating handle 420, and the two rod bodies 410 are connected by a spring 430, and an opening is formed between the two painting brush heads 100. Pinching the two operating handles 420 can make the opening larger so that the pipe can enter from the opening and be accommodated between the two painting brush heads 100. After loosening the two operating handles 420, the first roller brush 120 and the second roller brush 140 can be pressed on the pipe by the action of the spring 430 to ensure that when the painting tool is moved axially along the pipe, the first roller brush 120 and the second roller brush 140 are always in contact with the surface of the pipe to be painted.
