Description

Technical Field

[0001] This utility model belongs to the field of cosmetic technology, specifically relating to an eyebrow pencil. Background Technology

[0002] An eyebrow pencil is a device used for makeup. There are currently double-ended eyebrow pencils, with one end for drawing eyebrows and the other end for drawing eyeliner or other makeup components. However, existing twist-up eyebrow pencils tend to retract during use, affecting the makeup application effect. Therefore, it is very important to obtain an eyebrow pencil that prevents retraction. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides an eyebrow pencil, including at least one functional component, comprising:

[0004] Middle section components;

[0005] The pen tip is at least partially installed within the middle section assembly and rotatably connected to the middle section assembly;

[0006] The inner rod has a groove on the pen tip, at least part of which is located in the groove and slides within it to allow the material inside the inner rod to elongate relative to the pen tip. The inner rod is at least partially threaded to the inner wall of the middle section assembly. When the pen tip and the middle section assembly rotate, the pen tip drives the inner rod to rotate, causing the inner rod to elongate under the action of the thread.

[0007] At least one spring is provided on the outer wall of the pen tip of at least one of the functional components, the spring at least partially forming an anti-recoil protrusion, and an anti-recoil groove is provided on the inner wall of the middle section component to cooperate with the anti-recoil protrusion, so that the anti-recoil protrusion can only rotate in one direction, and when rotating in the other direction, the anti-recoil protrusion enters the anti-recoil groove to stop.

[0008] Through the above technical solution, the anti-retraction structure ensures that products such as eyebrow pencils can only extend and not retract. For example, when using eyebrow gel, which is restricted by the skull, traditional eyebrow pencils would retract along the threaded groove. However, this technology uses an anti-retraction slot to prevent retraction and increase stability during use.

[0009] Several anti-recoil grooves form a ratchet groove structure, and the spring piece cooperates with the ratchet groove structure to form an anti-recoil structure; there are two spring pieces; the spring piece and the pen tip are integrally formed.

[0010] The above technical solution, with the two springs symmetrically arranged at the center, can increase the anti-reverse effect and stability, and the one-piece molding design can simplify the production steps and reduce production costs.

[0011] The inner wall of the pen tip has a driving surface, and the outer wall of the inner rod has a driven surface that mates with the driving surface. When the pen tip rotates, the driving surface abuts against the driven surface, causing the inner rod to rotate. Both the driving surface and the driven surface are planar.

[0012] The middle section assembly includes a middle section body and a pen phase. The pen phase is snapped into the inner wall of the middle section body, and a threaded groove is formed on the inner wall of the pen phase. A cut is formed at the end of the inner rod, and a snap-fit ​​arm is formed on both sides of the cut. Each snap-fit ​​arm has a protrusion that mates with the threaded groove, so that the protrusion can move within the threaded groove.

[0013] The above technical solution enables stable movement of the inner rod in the threaded groove.

[0014] The inner wall of the middle section body is provided with several anti-rotation limiting strips, and the outer wall of the pen phase is provided with a matching limiting strip, which is located between two anti-rotation limiting strips. The inner wall of the middle section body is provided with a first snap-fit ​​groove, and the outer wall of the pen phase is provided with a first snap-fit ​​protrusion that matches the snap-fit ​​groove.

[0015] The aforementioned matching limit strip can prevent the circumferential rotation of the middle section body and the pen phase.

[0016] It also includes a pen barrel, the middle section body of the middle section assembly is installed inside the pen barrel, a second buckle protrusion is provided on the inner wall of the pen barrel, a third buckle protrusion is provided on the outer wall of the middle section body to cooperate with the second buckle protrusion, a plurality of anti-rotation strips are provided on the inner wall of the pen barrel, and a plurality of mating strips are provided on the outer wall of the middle section body, with the mating strips located between two anti-rotation strips.

[0017] A first sealing ring is provided between the pen tip and the middle section body; it also includes a pen cap, and a second sealing ring is provided between the inner wall of the pen cap and the middle section body.

[0018] Through the above technical solution, the sealing ring can keep the inner wall of this utility model airtight, so that the internal materials have a better service life.

[0019] The functional components are provided in two parts, located on both sides of the pen barrel.

[0020] The inner wall of the pen cap is fitted with a protective sleeve, and at least part of the pen tip of the functional component is inserted into the protective sleeve and abuts against the inner wall of the protective sleeve to prevent it from falling off, so as to better protect the pen tip.

[0021] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure and can prevent the pen tip from retracting during use. Attached Figure Description

[0036] Middle section component 1;

[0037] The pen tip 2 is at least partially installed within the middle section assembly 1 and rotatably connected to the middle section assembly 1;

[0038] The inner rod 3 has a groove 21 on the pen tip 2. The inner rod 3 is at least partially located in the groove 21 and slides within the groove 21 to allow the material in the inner rod 3 to elongate relative to the pen tip 2. The inner rod 3 is at least partially threaded to the inner wall of the middle section assembly 1. When the pen tip 2 and the middle section assembly 1 rotate, the pen tip 2 drives the inner rod 3 to rotate, so that the inner rod 3 elongates under the action of the thread.

[0039] At least one spring piece 22 is provided on the outer wall of the pen tip 2 of at least one of the functional components. The spring piece 22 at least partially forms an anti-recoil protrusion 23.

[0044] The middle section assembly 1 includes a middle section body 12 and a pen phase 13. The pen phase 13 is snapped into the inner wall of the middle section body 12, and a threaded groove 14 is formed on the inner wall of the pen phase 13. A cutout 32 is formed at the end of the inner rod 3, and a snap-fit ​​arm 33 is formed on both sides of the cutout 32. Each snap-fit ​​arm 33 is provided with a protrusion 34 that mates with the threaded groove 14, so that the protrusion 34 can move within the threaded groove 14.

[0045] The above technical solution enables the inner rod 3 to move stably in the threaded groove 14.

[0046] The inner wall of the middle section body 12 is provided with several anti-rotation limiting strips 15, and the outer wall of the pen phase 13 is provided with a matching limiting strip 16, which is located between two anti-rotation limiting strips 15. The inner wall of the middle section body 12 is provided with a first snap-fit ​​groove 17, and the outer wall of the pen phase 13 is provided with a first snap-fit ​​protrusion 18 that matches the snap-fit ​​groove.

[0049] A first sealing ring 51 is provided between the pen tip 2 and the middle section body 12; it also includes a pen cap 6, and a second sealing ring 52 is provided between the inner wall of the pen cap 6 and the middle section body 12.

[0050] Through the above technical solution, the sealing ring can keep the inner wall of this utility model airtight, so that the internal materials have a better service life.

[0051] The functional components are provided in two parts, located on both sides of the pen barrel 4.

[0052] The inner wall of the pen cap 6 is fitted with a protective sleeve 61. At least part of the pen tip 2 of the functional component is inserted into the protective sleeve 61 and abuts against the inner wall of the protective sleeve 61 to prevent it from falling off, so as to better protect the pen tip 2.
