[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a paint brush with a foldable brush head.

[0027] Reference Figure 1-3 A paint brush with a foldable brush head comprises a handle 1 and a brush head 4. A U-shaped plate 2 is fixedly arranged on the upper end of the handle 1, and a non-slip sleeve is fixedly sleeved on the lower end of the handle 1 to improve the stability of holding the paint brush. A rotating rod 3 is rotatably arranged on the inner side of the U-shaped plate 2, and the brush head 4 is fixedly sleeved on the rod wall of the rotating rod 3. A rotating wheel is fixedly sleeved on one end of the rotating rod 3, and a limiting mechanism for limiting the rotation of the rotating rod 3 is arranged between the rotating wheel and the U-shaped plate 2;

[0028] The outer wall of the brush head 4 is movably sleeved with a scraper ring 5, and the side wall of the brush head 4 is fixedly provided with two side plates 6, an internal threaded tube 7 is rotatably arranged between the two side plates 6, and the internal thread sleeve of the internal threaded tube 7 is provided with a threaded rod 8, and one end of the threaded rod 8 is fixedly connected to one end of the scraper ring 5.

[0029] In order to clean the residual paint on the brush head 4 during the storage process, refer to Figure 1-3, a transmission mechanism for driving the internal threaded tube 7 to rotate is arranged on the inner side of both ends of the U-shaped plate 2, and the transmission mechanism includes a first bevel gear 9 and a second bevel gear 11. Both ends of the rotating rod 3 are movably sleeved with a fixed tube 10, and one end of the fixed tube 10 is fixedly connected to the inner wall of one end of the corresponding U-shaped plate 2. The first bevel gear 9 is fixedly sleeved on one end of the internal threaded tube 7 close to the fixed tube 10, and the second bevel gear 11 is fixedly sleeved on one end of the fixed tube 10, and the first bevel gear 9 is meshedly connected with the second bevel gear 11;

[0030] During the rotation of the brush head 4, the first bevel gear 9 will be driven to revolve relative to the second bevel gear 11 which is fixedly arranged, that is, the first bevel gear 9 will rotate to drive the internal threaded tube 7 to rotate, and the internal threaded tube 7 will drive the threaded rod 8 which cannot rotate to move, that is, it can drive the scraper ring 5 to move, and scrape off the residual paint on the brush head 4, so as to prevent the paint 4 from dripping and causing pollution as much as possible.

[0031] In order to limit the position of the brush head 4 after the brush head 4 is rotated into place, refer to Figure 1-3 The limiting mechanism includes a stopper 13 and an insertion rod 15. A cavity is provided on one side of the rotating wheel. The stopper 13 is slidably arranged inside the cavity. The insertion rod 15 is fixedly sleeved in the middle of the stopper 13. Both ends of the insertion rod 15 extend to the outside of the cavity. A limiting tube 12 is fixedly arranged at one end of the U-shaped plate 2 and located on both sides of the rotating rod 3. One end of the insertion rod 15 is plugged into the corresponding limiting tube 12. A pull block is fixedly sleeved at one end of the outer side of the insertion rod 15 to facilitate pulling the insertion rod 15. A spring 14 is fixedly arranged on the side of the stopper 13 away from the limiting tube 12. The other end of the spring 14 is fixedly connected to the inner wall of the cavity to facilitate the stopper 13 to drive the insertion rod 15 to reset;

[0032] After the brush head 4 is rotated to the right position, the insertion rod 15 is released, and the elastic force of the spring 14 drives the stopper 13 to reset, so that the insertion rod 15 is inserted into the corresponding limiting tube 12, so that the rotating rod 3 cannot rotate, thereby stably limiting the brush head 4.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
