Description

Technical Field

[0001] This utility model relates to the field of rotating structure technology for cosmetic pens, and more specifically, it relates to a novel rotating structure for cosmetic pens. Background Technology

[0002] Makeup brushes are a common tool used for makeup in daily life. Makeup brushes can be classified according to the material of their lead: hard-core makeup brushes, liquid-core makeup brushes, and different types of makeup brushes can be used depending on the occasion.

[0003] Currently, most makeup brushes require an extension function during use. This function allows users to adjust the brush's position according to their habits and needs. The extension function also allows for precise control of the lead's extension, thus controlling the amount of makeup used. This caters to different makeup needs.

[0004] However, in existing makeup pens, the upward function can only rotate in one direction and cannot rotate in the opposite direction. Under such circumstances, users are prone to damaging the rotating upward structure, which will eventually lead to damage to the makeup pen and affect the user experience. A new rotating structure for makeup pens is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a novel rotating structure for cosmetic pens.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A novel rotating structure for a cosmetic pen includes a threaded rod, a connecting component sleeved on the outer side of the threaded rod, a rotating component engaged below the connecting component, a limiting component sleeved on the outer side of the connecting component, and an external connecting component sleeved on the outer side of the limiting component. The cooperation of the threaded rod, the rotating component, and the connecting component is used to control the linear upward movement of the threaded rod.

[0008] The threaded rod has a limit ring at its top and threads on its outer side wall.

[0009] The limiting component includes a limiting sleeve, and two sets of limiting blocks are symmetrically arranged on the outer side wall of the limiting sleeve.

[0010] The external component includes an external sleeve, and two sets of limiting slots are symmetrically opened on the outer side of the external sleeve. The shape of the limiting slots is adapted to the shape of the limiting block.

[0011] The connecting assembly includes a connecting sleeve, a ratchet is provided at the bottom of the connecting sleeve, and a threaded sleeve is provided at the bottom of the ratchet.

[0012] By adopting the above technical solution, the cooperation of the threaded rod, rotating component, and connecting component is used to control the linear ascent of the threaded rod. When the rotating component is turned, it contacts the connecting component, and the rotating component drives the connecting component to rotate. Since the limiting component and the external component mutually limit each other, and the connecting component and the limiting component mutually limit each other, and the threaded rod is restricted from axial rotation by the limiting component, the connecting component drives the threaded rod to rotate through the thread. Under the rotation of the connecting component, the threaded rod can achieve linear ascent. However, when the rotating component rotates in the opposite direction, no driving force is generated between the rotating component and the connecting component, that is, only the rotating component is spinning freely and does not have an effect on the threaded rod, so the threaded rod cannot descend. The shape of the limiting slot matches the shape of the limiting block, and the limiting slot and the limiting block cooperate to create a fixing structure and maintain the stability of the entire structure. The top of the connecting sleeve fits into the internal structure of the limiting sleeve, ensuring the stability of the rotating ascent structure.

[0013] The present invention is further configured such that: the inner wall of the threaded sleeve is provided with threads, and the thread shape of the inner wall of the threaded sleeve is adapted to the thread shape of the outer wall of the threaded rod.

[0014] By adopting the above technical solution, the stable rise of the structure is ensured by the matching of the threads, so that the threaded rod can rise in a straight line and is not easy to fall off from the connecting assembly.

[0015] The present invention is further configured such that: a through hole is provided at the top of the limiting sleeve, and the threaded rod is disposed inside the through hole, the through hole being used to restrict the axial rotation of the threaded rod.

[0016] The present invention is further configured such that: the through hole is a rectangular structure, and the two sides of the rectangular structure are semi-circular arcs.

[0017] The present invention is further configured such that: the rotating assembly includes a rotating sleeve, and a pawl is provided on the top of the rotating sleeve, the shape of the pawl being adapted to the shape of the ratchet.

[0018] The present invention is further configured such that: a torsion block is provided at the bottom of the rotating sleeve, and the torsion block, the rotating sleeve, and the ratchet are integrally formed.

[0019] By adopting the above technical solution, when the rotating sleeve rotates counterclockwise, the pawl rotates along with the rotating sleeve. At this time, the pawl drives the ratchet to rotate, and the ratchet drives the threaded sleeve to rotate together. Because the structure at the top of the connecting sleeve and the internal structure of the limiting sleeve mutually restrict each other, and the outside of the limiting sleeve is restricted by the limiting groove, the connecting sleeve can only be restricted between the limiting sleeve and the rotating sleeve. The threaded rod passes through the limiting sleeve, the connecting sleeve, and the rotating sleeve in sequence. Due to the restriction of the through hole, the threaded rod cannot rotate axially. The thread on the outer wall of the threaded rod meshes with the thread inside the threaded sleeve, thus... This device enables the threaded rod to rise linearly via rotation. When the rotating sleeve rotates clockwise, it drives the pawl to rotate. However, during this process, the lower side of the pawl has an adjustable clearance. As the pawl moves with the rotating sleeve, no pushing force is generated between the pawl and the threaded sleeve, and the pawl cannot drive the ratchet to rotate. In other words, only the pawl is spinning freely. Therefore, in practical applications, this rotating structure ensures that the threaded rod rises linearly when rotated counterclockwise, while clockwise rotation results in free rotation. This solves the problem of users damaging makeup pens due to accidental rotation and provides users with a better experience.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. By setting up a threaded rod, a rotating component, and a connecting component to work together, a rotating structure is designed to control the linear ascent of the threaded rod, achieving the purpose of the makeup pen rising in a straight line. At the same time, this rotating structure can also rotate in the opposite direction. During the reverse rotation, no driving force is generated between the rotating component and the connecting component, that is, only the rotating component is spinning freely and does not have any effect on the threaded rod, so the threaded rod cannot produce a descent effect. The reverse rotation function solves the problem of users damaging the makeup pen due to accidental rotation in daily life, bringing a better user experience.

[0022] 2. By setting through holes and limiting their shape, the through holes can restrict the axial rotation of the threaded rod, ensuring that the threaded rod can rise in a straight line during normal use, thus achieving the functions required by the makeup pen.

[0023] 3. By setting up a rotating structure, the product's structure will not be damaged when it is spinning freely, making it easy for users to handle and providing a stress-relieving experience, thus increasing the product's effectiveness. Attached Figure Description

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0037] Example 1, please refer to Figures 1-6 The present invention provides the following technical solution:

[0038] See Figures 1-3 A novel rotating structure for a cosmetic pen includes a threaded rod 1, which is the main rotating part. A connecting component 5 is sleeved on the outside of the threaded rod 1. The connecting component 5 is connected to the threaded rod 1 by threads. A rotating component 4 is engaged below the connecting component 5. The rotating component 4 is adapted to the connecting component 5. A limiting component 2 is sleeved on the outside of the connecting component 5. An external connecting component 3 is sleeved on the outside of the limiting component 2.

[0039] Among them, the bottom outer side of the rotating component 4 is also fitted with a tail cap for rotation, the outer side of the end of the threaded rod 1 is provided with a pen tube, the outer side of the pen tube and the outer side of the external component 3 is fitted with a pen sleeve, and the end of the pen tube is provided with a pen cap.

[0040] The threaded rod 1, the rotating assembly 4, and the connecting assembly 5 work together to control the linear ascent of the threaded rod 1. When the rotating assembly 4 is turned, the rotating assembly 4 comes into contact with the connecting assembly 5, and the rotating assembly 4 drives the connecting assembly 5 to rotate. Since the limiting assembly 2 and the external assembly 3 mutually limit each other, and the connecting assembly 5 and the limiting assembly 2 mutually limit each other, and the threaded rod 1 is restricted from axial rotation by the limiting assembly 2, the connecting assembly 5 drives the threaded rod 1 to rotate through the thread. Under the rotation of the connecting assembly 5, the threaded rod 1 can achieve linear ascent. However, when the rotating assembly 4 rotates in the opposite direction, no driving force is generated between the rotating assembly 4 and the connecting assembly 5. That is, only the rotating assembly 4 is spinning idly and does not have an effect on the threaded rod 1. The threaded rod 1 cannot produce a descent effect.

[0041] See Figures 1-3 A limit ring is provided at the top of the threaded rod 1, and threads are provided on the outer side wall of the threaded rod 1.

[0042] See Figures 1-3 The limiting component 2 includes a limiting sleeve 21, and two sets of limiting blocks 22 are symmetrically arranged on the outer side wall of the limiting sleeve 21.

[0043] See Figures 1-3 The external component 3 includes an external sleeve 31. Two sets of limiting slots 32 are symmetrically opened on both sides of the external sleeve 31. The shape of the limiting slots 32 is adapted to the shape of the limiting block 22. The limiting slots 32 and the limiting block 22 cooperate to form a fixed structure and maintain the stability of the entire structure.

[0044] See Figure 5 The connecting component 5 includes a connecting sleeve 51, a ratchet 53 at the bottom of the connecting sleeve 51, a threaded sleeve 52 at the bottom of the ratchet 53, and the top of the connecting sleeve 51 is fitted with the internal structure of the limiting sleeve 21 to ensure the stability of the rotating and rising structure.

[0045] See Figure 2 and Figure 6 The inner wall of the threaded sleeve 52 is provided with threads. The thread shape of the inner wall of the threaded sleeve 52 is adapted to the thread shape of the outer wall of the threaded rod 1. The matching of the threads ensures the stable rise of the structure, so that the threaded rod 1 can rise in a straight line and is not easy to fall off from the connecting assembly 5.

[0046] See Figure 2The top of the limiting sleeve 21 has a through hole 23, and the threaded rod 1 is disposed inside the through hole 23. The through hole 23 is used to limit the rotation of the threaded rod 1. The through hole 23 is rectangular in shape, and the two sides of the rectangular structure are semi-circular.

[0047] See Figure 2 and Figure 4 The rotating assembly 4 includes a rotating sleeve 41, and a pawl 42 is provided on the top of the rotating sleeve 41. The shape of the pawl 42 is adapted to the shape of the ratchet 53.

[0048] When the rotating sleeve 41 rotates counterclockwise, the pawl 42 rotates with the rotating sleeve 41. At this time, the pawl 42 drives the ratchet 53 to rotate, and the ratchet 53 drives the threaded sleeve 52 to rotate together. Since the structure at the top of the connecting sleeve 51 and the internal structure of the limiting sleeve 21 mutually restrict each other, and the outside of the limiting sleeve 21 is restricted by the limiting groove 32, the connecting sleeve 51 can only be restricted between the limiting sleeve 21 and the rotating sleeve 41. The threaded rod 1 passes through the limiting sleeve 21, the connecting sleeve 51 and the rotating sleeve 41 in sequence. Due to the restriction of the through hole 23, the threaded rod 1 cannot rotate axially. The thread on the outer wall of the threaded rod 1 meshes with the thread inside the threaded sleeve 52, so that the threaded rod 1 can rise linearly by rotation.

[0049] When the rotating sleeve 41 rotates clockwise, it drives the pawl 42 to rotate. However, during this process, the lower side of the pawl 42 has an adjustable clearance. As the pawl 42 moves with the rotating sleeve 41, no pushing force is generated between the pawl 42 and the threaded sleeve 52. The pawl 42 cannot drive the ratchet 53 to rotate, meaning that only the pawl 42 is spinning freely. Therefore, in practical applications, this rotating structure ensures that the threaded rod 1 rises in a straight line when rotated counterclockwise, while rotating clockwise results in free rotation. This solves the problem of users damaging makeup pens due to accidental rotation, providing users with a better experience. In addition, the free rotation structure makes it easy for users to handle and provides a stress-relieving experience.

[0050] See Figure 2 and Figure 4 The bottom of the rotating sleeve 41 is provided with a torsion block 43, and the torsion block 43, the rotating sleeve 41, and the pawl 42 are integrally formed.

[0051] Specifically, when the rotating lifting structure is applied, by rotating the torsion block 43, the pawl 42 rotates with the torsion block 43, and then the pawl 42 at the top of the torsion block 43 drives the ratchet 53 to rotate in a clockwise direction. The ratchet 53 drives the threaded rod 1 through the thread to achieve a straight upward effect, and finally achieves the effect of the makeup pen rotating upward.

[0052] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
