Detailed implementation manner

[0023] Please refer to Figures 1 - 5 , a paint roller brush capable of brushing arc surfaces, including a clamping mechanism 100 and a paint roller brush body 200 clamped on its top. A telescopic mechanism 300 is fixedly connected to the bottom of the clamping mechanism 100. The clamping mechanism 100 includes a mounting bracket 101:

[0024] Furthermore, a dual-axis motor 102 is fixedly connected to the center of the inner wall of the mounting bracket 101. The output ends on both sides of the dual-axis motor 102 are fixedly connected with threaded rods 103. The opposite ends of the threaded rods 103 are rotatably connected to a mounting plate 104. The opposite sides of the mounting plate 104 are fixedly connected to the left and right ends of the mounting bracket 101. A threaded sleeve 105 is threadedly connected to the surface of the threaded rod 103. The mutually close sides of the threaded sleeves 105 are fixedly connected with clamping pieces 107 that fit against the inner wall of the paint roller brush body 200.

[0025] The mounting bracket 101 serves as the basic structure of the entire device, used to install and support other components. The dual-axis motor 102 is located at the center of the inner wall of the mounting bracket 101, used to drive the rotation of the threaded rod 103. The threaded rod 103 is driven to rotate by the dual-axis motor 102 and cooperates with the limiting rod 106 to achieve the positioning and clamping of the paint roller brush body 200. The paint roller brush body 200 is the part that actually performs the painting. It is fixed by the clamping mechanism 100, and different specifications of the paint roller brush body 200 can be replaced according to needs. The telescopic mechanism 300 is located at the bottom of the clamping mechanism 100, used to adjust the height of the paint roller brush body 200, so that the paint roller brush body 200 can adapt to surfaces with different arcs and heights. In this device, the paint roller brush body 200 can be easily disassembled and replaced through the clamping mechanism 100, facilitating the use of different types of paint roller brushes. The paint roller brush body 200 can be easily disassembled, which is convenient for cleaning and maintenance. The height of the paint roller brush can be adjusted through the telescopic mechanism 300 to adapt to surfaces with different curvatures, which can improve work efficiency, reduce work intensity, and ensure the painting quality.

[0026] Further, a threaded sleeve 105 is slidably connected to the inner wall of the limit rod 106, and both the left and right ends of the threaded sleeve 105 are fixedly connected to the side of the mounting plate 104 close to each other.

[0027] When the bi-axial motor 102 is started, the threaded rod 103 starts to rotate, and the threaded sleeve 105 moves along the thread direction as the threaded rod 103 rotates. Since the threaded sleeve 105 is fixedly connected to the mounting plate 104, the limit rod 106 slides within the threaded sleeve 105, causing the clamping member 107 to approach the inner wall of the roller brush body 200, thereby clamping the roller brush body 200.

[0028] Further, the clamping member 107 includes a connecting plate 108 fixedly connected to one side of the limit rod 106. A first electric push rod 109 is rotatably connected to the side of the connecting plate 108 close to each other. The telescopic end of the first electric push rod 109 is fixedly connected to a center block 110, and the axis of the center block 110 and the axis of the roller brush body 200 are located on the same axis.

[0029] The center block 110 is installed at the telescopic end of the first electric push rod 109, and its axis is located on the same axis as the axis of the roller brush body 200. The design of the center block 110 ensures that the roller brush body 200 can maintain good concentricity during the clamping process, which is beneficial to the stable rotation of the roller brush body 200.

[0030] Further, a plurality of second electric push rods 111 are fixedly connected to the circumferential surface of the center block 110 at equal intervals. The telescopic ends of the plurality of second electric push rods 111 are fixedly connected to a first clamping plate 112, and the side of the first clamping plate 112 away from the second electric push rod 111 is attached to the inner wall of the roller brush body 200.

[0031] When it is necessary to clamp the roller brush body 200, the first electric push rod 109 extends, pushing the center block 110 to move towards the inner wall of the roller brush body 200. As the center block 110 moves, the plurality of second electric push rods 111 also extend accordingly, pushing the first clamping plate 112 into contact with the inner wall of the roller brush body 200. The first clamping plate 112 contacts the inner wall of the roller brush body 200 and applies a certain pressure, thereby clamping the roller brush body 200.

[0032] Further, fixed sleeves 113 are rotatably connected to the upper and lower positions on the side of the center block 110 close to each other. A sliding rod 114 is slidably connected to the inside of the fixed sleeve 113, and one end of the sliding rod 114 extends outside the fixed sleeve 113 and is rotatably connected to a second clamping plate 116.

[0033] As the center block 110 moves, the fixed sleeve 113 also moves accordingly. The sliding rod 114 slides within the fixed sleeve 113, and the spring 115 provides elastic force, causing the second clamping plate 116 to closely adhere to the inner wall of the roller brush body 200, realizing the clamping of the roller brush body 200.

[0034] Further, the second clamping plate 116 is correspondingly arranged at the upper and lower positions inside the drum brush body 200. The opposite side of the second clamping plate 116 is attached to the inner wall of the drum brush body 200. A spring 115 is fixedly connected between the sliding rod 114 and the fixed sleeve 113.

[0035] Through the elastic force provided by the spring 115, the second clamping plate 116 can automatically adjust the degree of fitting with the inner wall of the drum brush body 200 to ensure the reliability of clamping. The design of the second clamping plate 116 can well adapt to drum brush bodies 200 of different specifications to ensure the reliability of clamping. The combination of the second clamping plate 116 and the first clamping plate 112 can provide a more stable clamping effect, especially at the upper and lower positions of the drum brush body 200.

[0036] Further, a third electric push rod 117 is fixedly connected to the top of the lower second clamping plate 116. The telescopic end of the third electric push rod 117 is fixedly connected to the bottom of the upper second clamping plate 116.

[0037] When the third electric push rod 117 extends, it pushes the upper second clamping plate 116 to move downward, so that it clamps the drum brush body 200 together with the lower second clamping plate 116. When the third electric push rod 117 contracts, the upper second clamping plate 116 moves upward and separates from the lower second clamping plate 116. The drum brush body 200 is no longer under pressure and can be easily taken out or replaced from the clamping mechanism 100.

[0038] Further, the telescopic mechanism 300 includes a telescopic rod 301 fixedly connected to the bottom of the mounting frame 101. A plurality of first positioning holes 302 are equidistantly arranged on the surface of the telescopic rod 301. A sleeve 303 is slidably connected to the surface of the telescopic rod 301. A plurality of second positioning holes 304 are equidistantly arranged on the surface of the sleeve 303. A positioning bolt 305 is threadedly connected between the first positioning hole 302 and the second positioning hole 304. One end of the sleeve 303 away from the telescopic rod 301 is fixedly connected to a handle 306.

[0039] By holding the handle 306, the operator can slide the sleeve 303 along the length direction of the telescopic rod 301 to adjust the overall length of the telescopic mechanism 300. When the telescopic mechanism 300 is adjusted to the required length, the operator can select appropriate first positioning holes 302 and second positioning holes 304, and then use the positioning bolt 305 to pass through these two holes to lock the telescopic rod 301 and the sleeve 303 together to ensure that the telescopic mechanism 300 remains in the required position. Use the positioning bolt 305 to pass through the first positioning hole 302 and the second positioning hole 304 to lock the telescopic rod 301 and the sleeve 303 in the required position, so as to ensure that the telescopic mechanism 300 will not move accidentally during use and maintain the required extended length.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
