[0020] The utility model will be further explained in connection with the drawings and specific embodiments.

[0021] Please see the attached Figure 1 A telescopic roller brush, which comprises a brushing roller, a support long rod 3, a sleeve 4 and a position limiter 6; the brushing roller is installed at one end of the support long rod 3, and the other end of the support long rod 3 is inserted into the sleeve 4; an adjusting groove 5 is formed on the wall of the sleeve 4 along the length direction of the sleeve 4, the length of the adjusting groove 5 is less than the length of the sleeve 4, one end of the position limiter 6 is movably arranged on the other end of the support long rod 3 through a spring, the other end of the position limiter 6 penetrates to the outside of the sleeve 4 through the adjusting groove 5, and the middle part of the position limiter 6 can be clamped and fixed with the adjusting groove 5, so that the support long rod 3 and the sleeve 4 are connected to form a telescopic handle.

[0022] Preferably, the support long rod 3 and the sleeve 4 can be made of light hard plastic pipes, which can meet the requirements of non-deformation and damage and light use during use, and the diameter of the support long rod 3 is slightly smaller than the diameter of the sleeve 4, so that the support long rod 3 can be inserted into the sleeve 4 and flexibly extended and retracted relative to the sleeve 4, and the length of the support long rod 3 and the sleeve 4 can be adaptively selected according to actual use requirements.

[0023] By opening the adjusting groove 5 on the sleeve 4, when the support long rod 3 moves relative to the sleeve 4, the position limiter 6 moves along the adjusting groove 5 with the support long rod 3, compared with the traditional screw rotation adjustment, the telescopic movement efficiency of the support long rod 3 is higher, and the operation is more convenient. At the same time, the adjusting groove 5 can limit and guide the telescopic movement of the support long rod 3 through the position limiter 6, so as to ensure that the support long rod 3 moves linearly relative to the sleeve 4, and the movement is stable, controllable and efficient. By clamping and fixing the position limiter 6 on the adjusting groove 5, the telescopic movement of the support long rod 3 relative to the sleeve 4 can be limited, so as to fix the length of the telescopic handle and facilitate the brushing operation.

[0024] Preferably, the position limiter 6 can adopt a T-shaped structure, the small head end of the T-shaped structure is connected with the support long rod 3, the large head end of the T-shaped structure is located outside the sleeve 4 and has a width greater than the width of the adjusting groove 5, and the middle part of the T-shaped structure penetrates the adjusting groove 5. The length of the adjusting groove 5 is less than the length of the sleeve 4, which can limit the sliding amplitude of the position limiter 6 and avoid the support long rod 3 from being pulled out of the sleeve 4. The width of the adjusting groove 5 is slightly greater than the width of the middle part of the position limiter 6, so that the position limiter 6 can linearly slide under the limitation and guidance of the adjusting groove 5.

[0025] Please see the attached Figure 2The adjustment groove 5 has a plurality of first locking teeth 51 spaced apart on its groove wall, and the limiter 6 has a second locking tooth (not shown in the figure) in the middle. The second locking tooth can engage in the gap between any two adjacent first locking teeth 51, so that the limiter 6 is engaged and fixed on the adjustment groove 5.

[0026] By setting the first locking tooth 51, the second locking tooth is locked in place by the gap, which is used to limit the sliding of the second locking tooth relative to the adjustment groove 5, thereby limiting the sliding of the limiter 6 and realizing the connection and fixing function of the support rod 3 and the sleeve 4.

[0027] When the spring between the limiter 6 and the support rod 3 is at its natural length, the second locking tooth is precisely engaged in the gap between two adjacent first locking teeth 51. When the limiter 6 is pressed inward, the spring is compressed, and the second locking tooth disengages from the gap between the two adjacent first locking teeth 51. After the restriction is released, the support rod 3 can extend and retract relative to the sleeve 4.

[0028] Please see the appendix Figure 2 The first locking teeth 51 are symmetrically arranged on both sides of the adjustment groove 5, and the second locking teeth are provided in two and symmetrically arranged on both sides of the middle part of the limiter 6.

[0029] The symmetrical arrangement of the first and second locking teeth ensures that the limiter 6 is evenly stressed when it is fixedly engaged with the adjusting groove 5, guaranteeing the stability of the engagement and thus ensuring a reliable connection between the support rod 3 and the sleeve 4. To further improve connection reliability, multiple pairs of second locking teeth can be spaced apart on the limiter 6 to increase the contact area between the limiter 6 and the adjusting groove 5.

[0030] The gap width between any two adjacent first teeth 51 is consistent with the width of the second tooth, ensuring the positioning reliability of the limiter 6 on the adjustment groove 5.

[0031] Appendix Figure 2 The gap between two adjacent first locking teeth 51 shown is an isosceles trapezoidal structure. Correspondingly, the second locking tooth is also an isosceles trapezoidal structure, increasing the contact area for engagement and ensuring effective engagement of the second locking tooth within the gap, thus functioning as a locking and positioning limiter 6. Depending on actual usage requirements, the gap between two adjacent first locking teeth 51 can also be rectangular, triangular, or other structures. Correspondingly, the shape and dimensions of the second locking tooth are consistent with the shape and dimensions of the gap between the two adjacent first locking teeth 51.

[0032] Please see the appendix Figure 1 The coating roller includes a roller 1, a three-way pipe 2, and a roller support 8. The roller support 8 is a C-shaped structure with one end open. The roller 1 is rotatably mounted at the open end of the roller support 8 via a rotating shaft. The three-way pipe 2 is installed through two connecting ports in the middle of the other end of the roller support 8. The three-way pipe 2 is connected to one end of the support rod 3 via a third connecting port.

[0033] The roller bracket 8 can be made of lightweight hard plastic or lightweight metal, which facilitates the installation of the roller 1 and the painting operation of the roller 1. The tee pipe 2 can be connected to one end of the support rod 3 by threaded connection, which is convenient for disassembly and assembly to meet the replacement and cleaning needs of the roller 1.

[0034] Please see the appendix Figure 1 The end of the sleeve 4 away from the coating roller is fitted with a handle 7 via a connecting sleeve 71.

[0035] The grip 7 is easy to hold and more convenient to use. Preferably, the grip 7 can be equipped with a silicone anti-slip sleeve, which provides high stability and comfort when holding the hand.

[0036] Please see the appendix Figure 1 The handle 7 is provided with a hanging ring 72 at the end away from the sleeve 4, which is convenient for hanging and storing the entire roller brush.

[0037] Please see the appendix Figure 1 and attached Figure 2 The method of use and working principle of this utility model are as follows:

[0038] Depending on the height of the painting position, the construction worker presses the limiter 6, which compresses the spring between the limiter 6 and the support rod 3. The second locking tooth disengages from the gap between the two adjacent first locking teeth 51, allowing the support rod 3 to be moved telescopically relative to the sleeve 4 and adjusted to a suitable length.

[0039] After adjustment, release the limiter 6. Under the elastic force of the spring, the second locking tooth is pushed out and locked into the gap between the two adjacent first locking teeth 51 at the corresponding position, which is used to lock the support rod 3 and the sleeve 4.

[0040] The worker can hold the handle 7 and apply paint using the roller 1. After painting is complete or when roller 1 needs to be replaced, the paint roller can be detached from the support rod 3 by screwing on the T-connector 2 for cleaning or replacement. After cleaning, the entire roller can be stored by hanging it using the hanging ring 72.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
