Description

Technical Field

[0001] This utility model belongs to the field of cleaning tool technology, and specifically relates to a rotatable metal brush. Background Technology

[0002] A rotatable metal brush is a cleaning tool that uses an electric motor or other power source to drive the brush head to rotate, utilizing the friction and impact force of the bristles to remove dirt and impurities from the surface of an object. In industries such as metal processing and machinery manufacturing, rotatable metal brushes are commonly used to remove oil, rust, and oxide layers from metal surfaces. In the cleaning process of metal materials such as aluminum rods, rotatable metal brushes can efficiently remove surface dirt and impurities, improving cleaning efficiency and quality. The design of the brush head can be adjusted according to different cleaning needs, exhibiting high flexibility and adaptability. With the development of materials science, the brush head materials of future rotatable metal brushes will become more diversified, possessing higher hardness and wear resistance, while reducing damage to the surface being cleaned.

[0003] The use of a rotating metal brush may have the following drawbacks: prolonged friction between the metal bristles and the surface of the object being cleaned or processed will cause the bristles to gradually wear down, corrode, rust, and shorten, affecting the cleaning or processing effect. Therefore, the brush head needs to be replaced regularly. The brush head does not have a quick-disassembly structure and usually requires the use of special tools or complicated operations to replace it. This not only increases the difficulty and time of replacing the brush head, but may also lead to the risk of damaging the brush head or drive device during the replacement process.

[0025] Please see Figure 1-5 The technical solution provided in this embodiment is as follows:

[0026] A rotatable metal brush, comprising,

[0027] Handle 1, a rotating block 2 is rotatably provided on one side of the outer wall of handle 1, a locking block 7 is slidably provided on one side of the outer wall of rotating block 2, and a brush head 3 is rotatably provided on one side of the outer wall of locking block 7.

[0028] The quick-connect assembly is located on the inner wall of the rotating block 2. The quick-connect assembly includes two pressure rods 5, two first springs 6, two first fixing blocks 8, and two second fixing blocks 9. Each first fixing block 8 is rotatably disposed on the inner wall of the rotating block 2. Each pressure rod 5 is fixedly disposed on the outer wall of the corresponding first fixing block 8, and each pressure rod 5 slides through the interior of the rotating block 2. Each second fixing block 9 is fixedly disposed on the outer wall of the snap-fit ​​block 7. Two bolts are fixedly disposed on the outer wall of the rotating block 2. Each pressure rod 5 is slidably sleeved on the bolt. Each bolt has a nut threadedly connected to its outer wall.

[0029] In a specific embodiment of this utility model, the quick-connect assembly makes brush head 3 replacement simple and quick, without the need for complex tools or cumbersome operations. Users can quickly replace the appropriate brush head 3 according to different cleaning needs and tasks, improving work efficiency. Since brush head 3 can be quickly disassembled, users can more easily clean and maintain it, extending the service life of brush head 3 and the overall device. First, the second fixing block 9 inside the snap-fit ​​block 7 is snapped with the first fixing block 8. The first spring 6 provides support for the first fixing block 8, facilitating the continuous snap-fit ​​of the first fixing block 8 and the second fixing block 9. When it is necessary to disassemble brush head 3 and snap-fit ​​block 7, the pressure rod 5 can be pressed down to push the first fixing block 8 downwards, and the second fixing block 9... Disassembly can be achieved when the fixing block 9 is no longer engaged with the first fixing block 8. In addition, when the first spring 6 has no supporting force or the supporting force is small, the nut on the bolt inside the pressure rod 5 can be used to support the pressure rod 5 or restrict the position of the pressure rod 5, so that the first fixing block 8 and the second fixing block 9 can be engaged more tightly. The half gear 10 meshes with the limiting rod 11. The angle of the brush head 3 can be adjusted by pushing and pulling the limiting rod 11. The position of the limiting rod 11 is restricted by the engagement of the limiting plate 12 with the limiting rod 11. Then, the motor 4 drives the engaging block 7 and the brush head 3 to rotate. The first bolt 13 can prevent the limiting plate 12 from loosening or falling off during rotation. When the limiting plate 12 needs to be adjusted, the first bolt 13 can be removed.

[0030] Specifically, a motor 4 is fixedly installed on the inner wall of the handle 1, and the output end of the motor 4 is fixedly connected to the rotating block 2.

[0031] In a specific embodiment of this utility model, the output end of the motor 4 is fixedly connected to the rotating block 2, which can achieve stable power transmission.

[0032] Specifically, the locking block 7 is slidably provided with a limiting rod 11, and the limiting rod 11 passes through the locking block 7.

[0033] In a specific embodiment of this utility model, the limiting rod 11 passes through the locking block 7 and can slide inside the locking block 7.

[0034] Specifically, a half gear 10 is fixedly installed on the outer wall of the brush head 3, and the half gear 10 meshes with the limiting rod 11.

[0035] In a specific embodiment of this utility model, the half gear 10 meshes with the limiting rod 11, which facilitates the adjustment of the angle of the brush head 3.

[0036] Specifically, the outer wall of the snap-fit ​​block 7 is provided with a limiting plate 12 for rotation, and the inner wall of the snap-fit ​​block 7 is threaded with a first bolt 13, which slides through the inside of the limiting plate 12.

[0037] In a specific embodiment of this utility model, a limiting plate 12 is rotatably provided on the outer wall of the snap-fit ​​block 7 to facilitate the restriction of the sliding of the limiting rod 11.

[0038] Specifically, a second spring 14 is fixedly installed between the snap-fit ​​block 7 and the outer wall of the limiting plate 12.

[0039] In a specific embodiment of this utility model, a second spring 14 is fixedly provided between the snap-fit ​​block 7 and the outer wall of the limiting plate 12. The second spring 14 exerts a certain pulling force on the limiting plate 12 so that the limiting plate 12 is snapped onto the outer wall of the limiting rod 11.

[0040] Working principle:

[0041] First, engage the second fixing block 9 inside the snap-fit ​​block 7 with the first fixing block 8. The first spring 6 provides support for the first fixing block 8, ensuring the first fixing block 8 and the second fixing block 9 remain engaged. When it is necessary to disassemble the brush head 3 and the snap-fit ​​block 7, press down on the pressure rod 5 to push the first fixing block 8 downwards. The second fixing block 9 will then no longer be engaged with the first fixing block 8, allowing for disassembly. Alternatively, when the first spring 6 has little or no supporting force, the pressure rod 5 can be supported by the nut on the bolt inside the pressure rod 5. Alternatively, the position of the pressure rod 5 can be restricted to make the first fixing block 8 and the second fixing block 9 more tightly engaged. The half gear 10 meshes with the limiting rod 11. The angle of the brush head 3 can be adjusted by pushing and pulling the limiting rod 11. The position of the limiting rod 11 is restricted by the engagement of the limiting plate 12 with the limiting rod 11. Then, the motor 4 drives the engaging block 7 and the brush head 3 to rotate. The first bolt 13 can prevent the limiting plate 12 from loosening or falling off during rotation. When the limiting plate 12 needs to be adjusted, the first bolt 13 can be removed.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
