Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the cosmetic pencil comprises a middle section connecting mechanism, wherein the middle section connecting mechanism comprises a middle section 5 and a pencil holder 8, and one end of the middle section 5 extends into the pencil holder 8 and is connected into a whole. The pen holder 8 is internally provided with the pen phase 7, the pen phase 7 is internally provided with the inner rod 6, and the pen phase 7 is in threaded fit with the inner rod 6 and can be screwed in or out for a certain distance. The front end of the middle section 5 is provided with a pen point 2, and the pen point 2 can rotate relative to the middle section 5; the inner end of the pen point 2 is matched with the front end of the inner rod 6 and can drive the inner rod 6 to rotate; the front end of the inner rod 6 is provided with a pen core. Therefore, the pen core can be extended out for the user to make up through the structure, and can be retracted for the pen point 2 to protect the pen core, so that the service life of the cosmetic pen is prolonged.

With reference to fig. 3, 4 and 5, the inner end of the middle joint 5 is provided with a step portion 13, and the wall surface of the step portion 13 is provided with two or more hook portions 14, preferably two in this embodiment, and the two hook portions are respectively located on the left and right sides of the step portion 13. The hook part 14 protrudes from the surface of the step part 13 and is arranged along the axial direction of the middle section 5. The inner wall of the pen shaft 8 is provided with a limit block 15 corresponding to the hook 14, and preferably, the limit block 15 is arranged in the middle of the pen shaft 8 in the embodiment, so that the other side of the pen shaft 8 can have a larger space for installing other components. Therefore, the limiting block 15 on the inner wall of the penholder 8 is hooked by the hook part 14 protruding outwards, and the middle section 5 is installed and fixed on the penholder 8.

Compared with the prior art that the middle section 5 and the pen holder 8 are in threaded connection or are bonded and fixed by glue, in the embodiment, an installer only needs to insert the middle section 5 into the pen holder 8 and then rotate the middle section 5, generally rotates a small half circle or so, and can hook the hook part 14 to hook the limiting block 15, so that the middle section 5 is fixed in the pen holder 8 simply and quickly.

As shown in fig. 3 and 4, the hook portion 14 is further formed with a fixing groove 18 for engaging with the stopper 15. The hook portions 14 are each provided with a guide inclined surface 16, and the guide inclined surfaces 16 are used for guiding the stopper 15 to move into the fixing groove 18 of the hook portion 14, so that the hook portion 14 hooks the stopper 15.

Specifically, after the middle section 5 is inserted into the pen holder 8, if the limiting block 15 abuts against the guiding inclined plane 16, the installer can rotate the middle section 5, if the middle section 5 gradually extends into the pen holder 8, the rotating direction is proved to be correct, otherwise, the rotating direction can be adjusted. The guide inclined plane 16 gradually guides the limiting block 15 to move downwards to the area where the fixing groove 18 is located, when the limiting block 15 is clamped in the fixing groove 18, the middle section 5 cannot continue to rotate, and at the moment, the middle section 5 is installed on the pen holder 8. So that the installer can better and more quickly complete the installation of the middle section 5 on the barrel 8 by the guide slope 16.

The ratio of the total length of the circumferential projections of all the guide inclined planes 16 at the end part of the step part 13 to the circumferential length of the step part 13 is 0.4-0.6, and the ratio of the total length of all the guide inclined planes 16 to the circumferential length of the step part 13 is 0.7-1.1.

Referring to fig. 1 and 2, a mascara base 10 is provided at an outer end of the barrel 8, and a mascara brush 11 is installed on the mascara base 10. So that the user can make up eyelash using the mascara brush 11, realizing more functions, satisfying more demands of consumers.

Referring to fig. 1 and 2, a weight 9 is further provided in the barrel 8, one end of the weight 9 extends outward to form a stabilizing shaft 17, and the stabilizing shaft 17 is embedded in the middle of the mascara base 10; the mascara base 10 is clamped by the barrel 8 and the stabilizing shaft 17. Therefore, the eyelash seat 10 can be installed and stabilized in the penholder 8 by matching the stabilizing shaft 17 on the weighting block 9 with the inner wall of the penholder 8, the gravity center and the weight of the cosmetic pen can be adjusted by using the weighting block 9, and when a user performs makeup on eyelashes, the gravity center of the cosmetic pen can be positioned near a palm, so that the user can perform makeup operation with better hand feeling.

Further, referring to fig. 1 and 2, the mascara brush 11 and the writing tip 2 are respectively sleeved with the upper cap 12 and the lower cap 1, so that the mascara brush 11 and the writing tip 2 are protected by the upper cap 12 and the lower cap 1, and the mascara brush 11 and the writing tip 2 are prevented from being damaged by external force when the cosmetic pencil is stored.

With reference to fig. 1 and 2, a first sealing ring 3 is further sleeved at the inner end of the pen point 2, and the first sealing ring 3 is located between the pen point 2 and the middle section 5 and used for sealing a gap between the pen point 2 and the middle section 5, so that water or sundries are prevented from entering the cosmetic pencil, and the use of parts is prevented from being affected.

With reference to fig. 1 and 2, the outer end of the middle section 5 is sleeved with a second sealing ring 4, when the lower pen cap 1 is sleeved on the pen point 2, the outer end of the middle section 5 seals the opening of the lower pen cap 1, and the second sealing ring 4 deforms and abuts against the inner wall of the lower pen cap 1, so that a gap between the middle section 5 and the lower pen cap 1 is sealed, and water or sundries are prevented from entering the pen cap to influence the pen point 2 and the pen core therein. Meanwhile, due to the self resilience acting force of the sealing ring II 4, the friction force of the lower pen cap 1 arranged on the middle section 5 can be enhanced, and the lower pen cap 1 is prevented from falling off easily.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
