[0022] Example

[0023] This application discloses a foldable, telescopic plastic cosmetic brush holder. Please refer to [link / reference needed]. Figure 1 and Figure 4 The device includes a mounting base 2 and a base 4. The bottom surface of the mounting base 2 has a threaded groove 10, which is connected to the protrusion 14 by threads. The protrusion 14 is detachably connected to the external thread on the top of the protrusion 14 by thread engagement. The protrusion 14 is made of engineering plastic and is integrally injection molded. The bottom of the protrusion 14 is fixedly connected to the base 4 by hot melt welding to ensure the connection strength. A deep groove ball bearing is embedded in the center of the top of the base 4. The connecting column 13 forms a 360° free rotation structure with the base 4 through the bearing. The baffle 11 is disc-shaped and its diameter is adapted to the inner diameter of the housing 1. Multiple second slots 12 are evenly distributed along the circumference on the top surface to form a stepped limiting structure.

[0024] Please see Figure 2 , Figure 3 and Figure 4 The through groove 9 on the top surface of the mounting base 2 is a T-shaped groove structure. The groove width is larger than the outer diameter of the housing 1 to ensure smooth sliding without obvious shaking. Two L-shaped first slots 8 are symmetrically arranged on the inner side wall of the through groove 9. A rectangular locking block 5 is integrally formed on one side surface of the housing through injection molding. The size of the locking block 5 matches the first slot 8. When the housing 1 slides along the through groove 9, the locking block 5 moves horizontally and then vertically in the L-shaped slot to realize the automatic locking function during the extension and retraction process.

[0025] Please see Figure 1 and Figure 2 A rotating bushing is embedded in the center of the top surface of the housing 1. The rotating column 7 forms a rotating pair with the housing 1 through the bushing. The top of the rotating column 7 is connected to the rotating upper shell 3 by a pin. The inner wall of the rotating upper shell 3 is provided with a sealing ring that matches the inner wall of the housing 1. When closed, it forms a dustproof sealing structure. The rotating upper shell 3 is made of transparent plastic, which makes it easy for users to observe the internal makeup brush storage.

[0026] Please see Figure 2 and Figure 3The two L-shaped first slots 8 are symmetrically distributed. The corners of the slots are rounded to avoid stress concentration when the card block 5 slides. When the housing 1 is fully extended, the card block 5 is located at the top of the vertical section of the L-shaped slot. At this time, the extension length of the housing 1 is equal to the height of the mounting base 2, which meets the pick-and-place requirements of different usage scenarios. When the housing 1 is fully retracted, the card block 5 is located at the end of the horizontal section of the L-shaped slot.

[0027] Please see Figure 2 and Figure 4 Multiple second slots 12 are evenly distributed radially around the center of the baffle 11 to accommodate makeup brushes of different sizes. The inner sidewall of the slot is provided with anti-slip texture to increase the friction between the brush handle and the slot. The bottom of the baffle 11 is connected to the base 4 through the connecting post 13.

[0028] The implementation principle of this embodiment is as follows: In use, firstly, the rotating upper shell 3 is opened by rotation, at which time the buckle assembly 6 is unlocked. Then, as needed, the shell 1 can be extended and retracted from the mounting base 2 along the first slot 8 to make it easier to take out the makeup brush. When taking out the makeup brush, simply remove the brush handle from the second slot 12. After use, insert the brush handle into the second slot 12 on the baffle 11 to achieve fixed storage of the makeup brush. Next, rotate the rotating upper shell 3 into the shell 1 and lock it through the buckle assembly 6 to complete the closure of the brush tube. When it is necessary to carry the brush tube out, if the size is too large, the locking block 5 and the first slot 8 can be extended and retracted to make the brush tube fold and extend, reducing the size and making it easy to carry. After arriving at the destination, the brush tube can be unfolded to return to the normal use state.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
