Technical Field

[0001] This utility model relates to the field of wall coating brush technology, and in particular to a special coating brush for solving the problem of external corner treatment. Background Technology

[0002] In the wall painting process of building decoration, it is necessary to paint the external corners of the wall. Since ordinary flat brushes cannot adhere to both sides of the external corners, the coating is uneven. Therefore, a special painting brush for external corner treatment has been developed. However, the brush head of existing corner-specific paintbrushes is fixed and cannot be adjusted according to the tilt angle of the wall. As a result, the brush head does not fit well with the corner, leading to uneven application. To address this issue, we propose a special paint brush for corner treatment. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a special coating brush for treating external corners.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A special painting brush for treating external corners includes a brush head, a support rod inserted at the center of the brush head, and a locking block fixedly connected to the bottom end of the support rod. The surface of the locking block is fitted with a locking groove, and a limiting mechanism is inserted through the surface of the locking block at the center-up position. The limiting mechanism includes a hollow rod fixedly installed inside the locking block, and a connecting rod fixedly connected to the bottom end of the locking groove. A handle is fixedly connected to the bottom end of the connecting rod, and an extension inner rod is fixedly connected to the bottom end of the handle.

[0005] Preferably, the front and rear surfaces of the card slot are provided with arc-shaped grooves, and the arc-shaped grooves are located on the right side of the center position. The front and rear ends of the hollow rod pass through the arc-shaped grooves for easy manipulation.

[0006] Preferably, a fixing block is fixedly installed at the center of the hollow rod, and a hole is opened in the center of the fixing block. A movable rod is inserted inside the hollow rod, and the movable rod passes through the fixing block and is connected to the fixing block by a bearing.

[0007] Preferably, the surface of the movable rod has opposite external threads from the center to both sides, and the surface of the movable rod is symmetrically fitted with threaded sleeves, and the threaded sleeves are threadedly connected to the movable rod, and the threaded sleeves move in opposite directions along the threads on the surface of the movable rod.

[0008] Preferably, the top of the hollow rod is provided with a slide rail, and a through-slide rail connecting threaded sleeve and a limiting plate are inserted inside the slide rail. The surface of the limiting plate that abuts against the slot is provided with an anti-slip pad, which can play a role in reinforcement and stability.

[0009] Preferably, the surface of the extended inner rod is fitted with an extended outer rod, and the inner wall of the extended outer rod has an internal thread adapted to the extended inner rod, and the outer wall of the extended outer rod is provided with anti-slip texture.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this device, the angle of the brush head is adjusted by bending the support rod, which improves the fit between the brush head and the external corner, thus making the brushing more uniform. The opposing movement between the threaded sleeves is adjusted by rotating the movable rod to achieve a fixed limit function, improving the stability of the brush head and further enhancing the practicality of the device.

[0014] 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.

[0015] Reference Figure 1-5A special painting brush for solving the problem of external corner treatment includes a brush head 1, a support rod 2 inserted at the center of the brush head 1, and a locking block 3 fixedly connected to the bottom end of the support rod 2. A locking groove 4 is provided on the surface of the locking block 3. A limiting mechanism 9 is inserted through the surface of the locking block 3 at the center upward position. The limiting mechanism 9 includes a hollow rod 91 fixedly installed inside the locking block 3. A connecting rod 5 is fixedly connected to the bottom end of the locking groove 4. A handle 6 is fixedly connected to the bottom end of the connecting rod 5. An extension inner rod 8 is fixedly connected to the bottom end of the handle 6.

[0016] Furthermore, refer to Figure 2 It can be seen that the front and rear surfaces of the card slot 4 are provided with arc-shaped grooves, and the arc-shaped grooves are located on the right side of the center position. The front and rear ends of the hollow rod 91 pass through the arc-shaped grooves for easy manipulation. During use, the hollow rod 91 drives the card block 3 to rotate inside the card slot 4, thereby facilitating the adjustment of the angle of the brush head 1.

[0017] Furthermore, refer to Figure 5 It can be seen that a fixing block is fixedly installed at the center of the hollow rod 91, and a hole is opened in the center of the fixing block. A movable rod 92 is inserted inside the hollow rod 91, and the movable rod 92 passes through the fixing block and is connected to the fixing block by a bearing.

[0018] Furthermore, refer to Figure 5 It can be seen that the surface of the movable rod 92 has opposite external threads from the center to both sides, and the surface of the movable rod 92 is symmetrically fitted with threaded sleeves 93, and the threaded sleeves 93 and the movable rod 92 are connected by threads. During use, the transmission function is achieved through the threads.

[0019] Furthermore, refer to Figure 4 and Figure 5 It can be seen that the top of the hollow rod 91 is provided with a slide rail, and a limiting block 94 is inserted inside the slide rail. The limiting block 94 passes through the slide rail and connects the threaded sleeve 93 and the limiting plate 95. During use, the limiting block 94 can achieve the limiting, which facilitates its linear movement.

[0020] Furthermore, refer to Figure 4 It can be seen that the surface of the extended inner rod 8 is fitted with the extended outer rod 7, and the inner wall of the extended outer rod 7 has an internal thread that matches the extended inner rod 8. The outer wall of the extended outer rod 7 is provided with anti-slip texture. During use, by rotating the extended outer rod 7 and moving it along the surface of the extended inner rod 8, the length of the extended inner rod 8 can be adjusted, thereby increasing the usable range of the brush head 1.

[0021] Working principle: When using this utility model, according to the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown, when it is necessary to adjust the length of the inner extension rod 8, the worker holds the handle 6 with one hand and rotates the outer extension rod 7 with the other hand. The outer extension rod 7 moves downward along the surface of the inner extension rod 8, extending the length of the inner extension rod 8, which makes it easier to paint higher areas. When the angle of the brush head 1 needs to be adjusted, the operator manually rotates the movable rod 92. The rotation of the movable rod 92 causes the threaded sleeve 93 to move on its surface. During the movement, the threaded sleeve 93 drives the limiting plate 95 to move through the limiting block (94). The limiting plate 95 moves away from the outer wall of the slot 4, and the locking block 3 is released. Then the operator rotates the support rod 2 to change the angle of the brush head 1. When the support rod 2 rotates, it drives the locking block 3 connected to its bottom end to rotate. The rotation of the locking block 3 drives the limiting mechanism 9 to rotate along the slide rail. After the adjustment is completed, the operator manually rotates the movable rod 92. The rotation of the movable rod 92 drives the threaded sleeve 93 to reset. The threaded sleeve 93 drives the limiting plate 95 to reset through the limiting block (94), which facilitates the limiting of the adjusted locking block 3, and thus facilitates the fixing of the adjusted brush head 1, which facilitates the painting of the external corners at different angles. The operation is completed. The above is the complete working principle of this utility model.
