[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 4 A connecting structure and an easy-to-replace indoor decoration roller brush includes a brush rod 1, a brush cylinder 2 connected to the brush rod 1, two symmetrically arranged connecting components 3 connected to one end of the brush rod 1 near the brush cylinder 2, and a disassembly component 4 provided between the two connecting components 3, the disassembly component 4 extending to the outside of the brush rod 1.

[0024] The main improvement of this utility model lies in enhancing the ease of use of the roller brush, such as... Figures 1 to 4 As shown, the connecting structure and easy-to-replace roller brush for interior decoration in this utility model are used by inserting the brush rod 1 into one end of the brush cylinder 2 and supporting it on the inside of the brush cylinder 2 through two connecting components 3, thereby fixing the brush cylinder 2 to the outside of the brush rod 1. When it is necessary to remove the brush cylinder 2 from the brush rod 1, the connecting component 3 can be quickly separated from the brush cylinder 2 through the disassembly component 4, thereby quickly removing the brush cylinder 2 from the brush rod 1 and improving the convenience of using the roller screen in interior decoration.

[0025] like Figures 1 to 3 As shown, two bearings 5 ​​are connected to the outer wall of the brush rod 1 near the brush cylinder 2. The inner rings of the two bearings 5 ​​are fitted onto the brush rod 1 and fixedly connected to the outer wall of the brush rod 1. Two connecting components 3 are respectively connected to the outer rings of the two bearings 5. The connecting components 3 can rotate more smoothly on the brush rod 1 through the bearings 5. When the brush cylinder 2 is installed on the brush rod 1 through the connecting components 3, the bearings 5 ​​can make the wall coating operation smoother and more successful when coating the wall, ensuring that the brush cylinder 2 rolls smoothly on the wall, improving the stability of the wall coating operation and improving the wall coating effect.

[0026] like Figures 1 to 4As shown, the connecting assembly 3 includes several elastic clips 31, which are distributed around the circumference of the bearing 5 on the outer ring of the bearing 5. One end of the elastic clip 31 is fixedly connected to the outer ring of the bearing 5, and the end of the elastic clip 31 away from the bearing 5 extends obliquely away from the brush rod 1. The elastic clips 31 on the outer sides of the two bearings 5 ​​extend to the side away from each other, and the end of the elastic clip 31 away from the bearing 5 abuts against the inner wall of the brush cylinder 2. Multiple elastic clips 31 extend outwards and press against the inner wall of the brush cylinder 2. When installing the brush cylinder 2 onto the brush rod 1, firstly, several elastic clips 31 at the end of the brush rod 1 are pressed inwards. Then, the pressed elastic clips 31 are inserted into the brush cylinder 2, and the brush rod 1 is inserted into the brush cylinder 2. The outer side of the extended end of another set of elastic clips 31 is pressed into the brush cylinder 2 by the end of the brush cylinder 2. Once both sets of elastic clips 31 are completely inside the brush cylinder 2, the installation of the brush cylinder 2 on the brush rod 1 is complete. During the wall coating process, a certain amount of force is usually applied. To ensure that the brush cylinder 2 can make close contact with the wall, the elastic deformation force of the elastic clip 31 needs to have a certain strength. This is necessary to meet the pressure required for wall coating while ensuring that the elastic clip 31 is always pressed against the inside of the brush cylinder 2 to prevent the connection between the brush cylinder 2 and the brush rod 1 from loosening. At the same time, even if the elastic clip 31 undergoes a small deformation under pressure during the wall coating process, the side of the same set of multiple elastic clips 31 away from the wall can still be pressed against the inside of the brush cylinder 2. Therefore, the connection stability between the brush cylinder 2 and the brush rod 1 is guaranteed to a certain extent.

[0027] like Figures 1 to 4As shown, the disassembly assembly 4 includes a clip sleeve 41 and a pull rope 42. The clip sleeve 41 is sleeved on the outside of the brush rod 1 and is located between two bearings 5. One end of the pull rope 42 is connected to the clip sleeve 41, and the other end of the pull rope 42 extends to the outside of the brush cylinder 2. The inner diameter of the clip sleeve 41 is larger than the outer ring diameter of the bearing 5, and the inner wall of the clip sleeve 41 is slidably connected to the outer wall of a plurality of elastic clips 31. When installing the brush cylinder 2, the clamp sleeve 41 can be moved towards the elastic clamp 31 at one end of the brush rod 1 that is inserted into the brush cylinder 2, and the multiple elastic clamps 31 can be squeezed and retracted to the inside of the clamp sleeve 41, thus facilitating the insertion of the elastic clamps 31 into the inside of the brush cylinder 2. Subsequently, the elastic clamp 31 on the outside of the bearing 5 at the other end can be squeezed against the end of the brush cylinder 2, thus smoothly entering the brush cylinder 2. Then, by pulling the clamp sleeve 41 with the pull rope 42, the inner elastic clamps 31 are released, thereby allowing the elastic clamps 31 on the inside of the clamp sleeve 41 to... The brush rod 1 is installed by pushing the brush rod outward and pressing it against the inner wall of the brush cylinder 2. When the brush cylinder 2 needs to be replaced, the pull rope 42 can be pulled to move the clamp sleeve 41 towards the bearing 5 near the end of the pull rope 42, and the elastic clamp 31 on the outside of the bearing 5 is squeezed and retracted into the clamp sleeve 41. Then the brush rod 1 can be pulled outward from the brush cylinder 2. The elastic clamp 31 on the outside of the bearing 5 at the other end is forced to retract inward, and the brush rod 1 can be pulled out of the brush cylinder 2 smoothly, completing the disassembly operation of the brush cylinder 2 on the brush rod 1.

[0028] like Figures 1 to 4 As shown, a groove 101 is formed through the side wall of the brush rod 1, located between two bearings 5. A sliding rod 6 is slidably connected within the groove 101. Both ends of the sliding rod 6 extend from the sides of the groove 101 and are fixedly connected to the middle position of the inner wall of the clamp sleeve 41. One end of the pull rope 42 is fixedly connected to one side of the middle position of the sliding rod 6, and the other end of the pull rope 42 extends from one end of the groove 101 to the outside of the brush rod 1. The clamp sleeve 41 slides within the groove 101 of the brush rod 1 via the sliding rod 6, making the pull rope 42 more stable when pulling the clamp sleeve 41 and preventing the clamp sleeve 41 from rotating on the brush rod 1, which would cause the pull rope 42 to wrap and shrink, thus improving the stability of the pull rope 42.

[0029] like Figures 1 to 4 As shown, limit grooves 102 are provided on both sides of the slide groove 101, and limit blocks 61 are fixedly connected to both sides of the slide rod 6. The two limit blocks 61 are slidably connected to the two slide rods 6 respectively. The limit blocks 61 prevent the clamp sleeve 41 from wobbling up and down on the brush rod 1, ensuring that the pull rope 42 is always in the middle position. This ensures that when the pull rope 42 is pulled, the clamp sleeve 41 can stably squeeze and retract the elastic clamp 31 to the inside, improving the stability of the brush cylinder 2 disassembly operation.

[0030] like Figures 1 to 4As shown, two arc-shaped limiting plates 7 are fixedly connected to the outer wall of the brush rod 1 between the two bearings 5. The two arc-shaped limiting plates 7 are located on both sides of the slide groove 101, and the inner wall of the clamping sleeve 41 is slidably connected to the outer wall of the two arc-shaped limiting plates 7. The arc-shaped limiting plates 7 support the clamping sleeve 41 on the inner side, further ensuring the stability of the movement of the clamping sleeve 41 on the outer side of the brush rod 1.

[0031] like Figures 1 to 4 As shown, the end of the pull rope 42 that extends to the outside of the brush rod 1 is provided with a knot 8. The knot 8 makes it easier to pull the pull rope 42, and at the same time, the knot 8 can prevent the end of the pull rope 42 from retracting into the through hole of the brush rod 1, ensuring that the end of the pull rope 42 is on the outside of the brush rod 1, which facilitates the pulling operation of the pull rope 42.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
