Abstract
Description
Technical Field
[0001] The utility model relates to a cosmetic brush with a brush head that can be rotatably adjusted. Background Art
[0002] Prior art, such as Chinese utility model patent document, publication number CN219742106U, discloses a cosmetic brush that is easy to replace the brush head, belonging to the technical field of cosmetic brushes, comprising: a brush handle, a telescopic rod slidably connected inside the brush handle, a fixed block symmetrically arranged on the telescopic rod, a rotating block rotatably connected to the fixed block, a connecting plate fixedly connected to the surface of the rotating block, a mounting block fixedly installed on the connecting plate, a limiting groove is provided on the mounting block, and magnet columns are symmetrically arranged in the limiting groove. This scheme arranges an angle adjustment component, and the rotating mounting block drives the brush head to adjust the angle. When it is adjusted to the desired angle, the locking nut is rotated to lock the angle of the brush head.
[0003] In the prior art, the angle of the brush head can be locked by an angle adjustment component. The technical problem is that the overall structure of the angle adjustment component is complex and the number of parts is large, which is not conducive to improving assembly efficiency and reducing production costs, and needs further improvement. Utility Model Content
[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a cosmetic brush with a brush head that can be rotatably adjusted.
[0005] A cosmetic brush with a rotatable and adjustable brush head designed for this purpose comprises a brush handle and a brush head, wherein a mounting groove is arranged at the front end of the brush handle, and a connecting block is arranged at the rear end of the brush head, and the connecting block is rotatably arranged in the mounting groove. A plurality of positioning grooves are arranged on the connecting block, and the plurality of positioning grooves are arranged in a circle along the rotation axis of the connecting block. A positioning block is arranged in the mounting groove, and the positioning block can be embedded in any one of the positioning grooves to form a positioning.
[0006] Preferably, the upper and lower end surfaces of the connecting block are respectively provided with convex shafts, and the upper and lower side wall surfaces of the mounting groove are respectively provided with axial holes, and the convex shafts are rotatably arranged in the axial holes.
[0007] Preferably, guide grooves are respectively arranged on the upper and lower side walls of the installation groove, the front end of the guide groove passes through the brush handle and is arranged to be open, the shaft hole is arranged in the guide groove, and the shaft hole is arranged to be recessed relative to the guide groove.
[0008] Compared with the prior art, the utility model sets a positioning groove and a positioning block to achieve angle limiting. When in use, the brush head rotates relative to the brush handle, and the positioning block is separated from the original positioning groove and then enters the next positioning groove to achieve angle limiting. Compared with the prior art, this solution has the advantages of simple structure and convenient assembly, which can effectively reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0015] See also Figure 1-Figure 5 , Figures 1 to 4 The first embodiment of a cosmetic brush with a brush head that can be rotated and adjusted. Figure 5 The second embodiment of a cosmetic brush with a rotatable and adjustable brush head comprises a brush handle 1 and a brush head 2. A mounting groove 11 is provided at the front end of the brush handle 1, and a connecting block 21 is provided at the rear end of the brush head 2. The connecting block 21 is rotatably provided in the mounting groove 11. The rear end surface of the connecting block 21 is an arcuate surface 20, and a plurality of positioning grooves 23 are provided on the arcuate surface 20. The plurality of positioning grooves 23 are arranged in a circle along the rotation axis of the connecting block 21. A positioning block 12 is provided in the mounting groove 11, and the positioning block 12 can be embedded in any one of the positioning grooves 23 to form a positioning.
[0016] Based on the above embodiment, when in use, the brush head rotates relative to the brush handle, the positioning block is separated from the original positioning groove and then enters the next positioning groove to achieve angle limiting. Compared with the prior art, this solution has the advantages of simple structure and convenient assembly, which can effectively reduce production costs.
[0017] See also Figure 1 and Figure 2The installation groove 11 is a groove with openings on the front side and both the left and right sides. This design is to enable the brush head 2 to rotate relative to the brush handle 1 after the connection block 21 is assembled.
[0018] See also Figure 2 and Figure 3 The upper and lower end surfaces of the connecting block 21 are respectively provided with convex shafts 22 , and the upper and lower side wall surfaces of the mounting groove 11 are respectively provided with shaft holes 13 , and the convex shaft 22 is rotatably arranged in the shaft holes 13 .
[0019] See also Figure 2 and Figure 3 The upper and lower side walls of the mounting groove 11 are respectively provided with guide grooves 14 , the front end of the guide groove 14 penetrates the brush handle 1 and is open, the shaft hole 13 is arranged in the guide groove 14 , and the shaft hole 13 is recessed relative to the guide groove 14 .
