[0035] The pearl part 150 includes a lifting lipstick tube 160 arranged in the upper chamber 120, and a spiral lifting rod 170 arranged at the lower end of the lifting lipstick tube 160 and extending into the lower chamber 130 from the limiting hole 140 and slidingly matched in the limiting hole 140;

[0036] A knob bottom cover 180 is arranged in the lower chamber 130, and a second chamber 190 is arranged in the knob bottom cover 180, and a threaded connection hole 200 is arranged at the top end of the knob bottom cover 180, the spiral lifting rod 170 is screw-connected with the threaded connection hole 200, and the lower end of the spiral lifting rod 170 extends into the threaded connection hole 200 and is matched with the second chamber 190 in lifting;

[0037] Through the cooperation of the spiral lifting rod 170 and the threaded connection hole 200 in the knob bottom cover 180, the user can more finely control the extension length of the lipstick core, and the problem of too long or too short exposure of the lipstick caused by the traditional push-pull structure is avoided;

[0038] The limiting plate 110 divides the first chamber into the upper chamber 120 and the lower chamber 130, and guides the movement of the spiral lifting rod 170 through the limiting hole 140, the limiting hole 140 limits the rotation of the spiral lifting rod 170 in the circumferential direction, so that the spiral lifting rod 170 can only be linearly adjusted, which not only ensures the stability and straightness of the lifting process, but also prevents the spiral lifting rod 170 from deviating or jamming during the lifting process;

[0039] In the assembling process of the utility model, the lifting lipstick tube 160 and the spiral lifting rod 170 are inserted into the upper chamber 120 and installed downward, so that the lower end of the spiral lifting rod 170 extends into the lower chamber 130, then the knob bottom cover 180 is inserted into the lower chamber 130 and installed upward, so that the spiral lifting rod 170 is screw-connected with the threaded connection hole 200 in the knob bottom cover 180, and the assembly of the utility model lipstick is completed;

[0040] The utility model lipstick structure adopts the ingenious combination of the middle beam tube 100, the limiting plate 110 and the pearl part 150 and other components, so that the whole lipstick structure is more compact, space is saved, and a smaller and more portable product can be manufactured, the convenience and reliability of the lipstick are improved, and the assembly efficiency is high, and the labor cost and time cost in the production process are saved.

[0041] In the embodiment of the utility model, first plane parts 210 and first arc surface parts 220 are arranged on the side wall of the spiral lifting rod 170 along the length direction;

[0042] An inner wall of the limiting hole 140 is formed with a second flat surface 230 that abuts against the first flat surface 210;

[0043] The side wall of the spiral lifting rod 170 is provided with a first flat surface 210 and a first arc surface 220 along the length direction, and the inner wall of the limiting hole 140 is formed with a second flat surface 230 that abuts against the first flat surface 210. This design ensures that the spiral lifting rod 170 can move along the predetermined path when it is lifted or lowered, avoiding the problem of deflection or tilting;

[0044] Due to the cooperation between the first flat surface 210 and the second flat surface 230, the spiral lifting rod 170 will not rotate unnecessarily during lifting or lowering, enhancing the stability of the structure;

[0045] The design of the first flat surface 210 and the second flat surface 230 allows the spiral lifting rod 170 to smoothly slide within the limiting hole 140, reducing frictional resistance and making it easier for users to adjust the exposed length of the lipstick core;

[0046] Through the combination of flat surfaces and arc surfaces, stable lifting function can be achieved without additional anti-rotation mechanisms, simplifying the internal mechanical structure and reducing manufacturing complexity and cost;

[0047] In one embodiment, the first flat surface 210 and the first arc surface 220 are respectively provided with a plurality of circumferential arrangements along the side wall of the spiral lifting rod 170;

[0048] In one embodiment, the second flat surface 230 is provided with a plurality of circumferential arrangements along the inner wall of the limiting hole 140.

[0049] In the embodiment of the utility model, the side wall of the first arc surface 220 is provided with a screw thread 240 that screws with the threaded connection hole 200 along the length direction;

[0050] The screw thread 240 screws with the threaded connection hole 200, providing stable mechanical connection for the spiral lifting rod 170. This design not only enhances the overall stability of the structure, but also effectively transmits the torque generated when the knob bottom cover 180 rotates, ensuring accurate control of the lipstick core extension;

[0051] The cooperation between the screw thread 240 and the threaded connection hole 200 ensures good connection even under external vibration or impact, reducing the risk of loosening;

[0052] Compared with other designs that may require additional anti-rotation devices or complex mechanisms, this scheme achieves stable positioning and lifting adjustment function through simple geometric shapes (flat surfaces and arc surfaces) and screw thread 240 structure, simplifying the internal structure and improving the reliability of the system.

[0053] In the embodiment of the utility model, the lower end of the first plane part 210 extends into the lower cavity, a limiting boss 260 is fixedly arranged on the part of the first plane part 210 extending into the lower cavity, and the upper end surface of the limiting boss 260 abuts against the lower end surface of the limiting plate 110;

[0054] The design of the limiting boss 260 ensures that the spiral lifting rod 170 cannot be excessively adjusted, and avoids the risk of the spiral lifting rod 170 sliding out of the limiting hole 140. This provides additional safety for the entire structure, preventing internal components from falling off or being damaged due to misoperation;

[0055] The abutting cooperation of the limiting boss 260 and the lower end surface of the limiting plate 110 can provide a clear mechanical stop point;

[0056] Through the contact between the limiting boss 260 and the limiting plate 110, the contact points in the system are increased, further enhancing the stability of the structure and reducing the shaking or instability that may occur during use;

[0057] The existence of the limiting boss 260 can disperse the force, reduce the direct friction between the limiting plate 110 and the spiral lifting rod 170, thereby reducing the wear speed between the two and prolonging the service life of the product.

[0058] When the spiral lifting rod 170 rises to the top end, the contact of the limiting boss 260 and the limiting plate 110 will produce a clear operation touch, informing the user that the highest position has been reached, improving the user experience.

[0059] In the embodiment of the utility model, the lower end surface of the limiting boss 260 is provided with a chamfered portion 270;

[0060] During the production and assembly process, the chamfered portion 270 can serve as a guide structure during the process of the lower end of the spiral lifting rod 170 extending into the upper chamber 120 and being installed downward, helping the limiting boss 260 to be more easily aligned and enter the limiting hole 140, simplifying the assembly process and improving the production efficiency.

[0061] In the embodiment of the utility model, the inner wall of the second chamber 190 is fixedly provided with a mounting plate 280, the upper end surface of the mounting plate 280 is formed with a connecting pipe 290, and the threaded connection hole 200 is arranged on the inner wall of the connecting pipe 290;

[0062] The arrangement of the mounting plate 280 increases the rigidity of the internal structure of the knob bottom cover 180, especially when subjected to the torque applied by the spiral lifting rod 170, it can provide stronger support force to prevent deformation or damage;

[0063] The design of the connecting pipe 290 ensures that the threaded connection hole 200 is accurately aligned with the screw thread 240 on the screw lifting rod 170, avoiding misalignment problems caused by assembly errors, and ensuring smooth screw transmission.

[0064] By integrating the threaded connection hole 200 in the connecting pipe 290, the friction and pressure directly acting on the body of the knob bottom cover 180 can be effectively reduced, thereby prolonging its service life and reducing wear and tear.

[0065] The mounting plate 280 and the connecting pipe 290 provide stable support, allowing users to obtain a more stable and consistent operating experience when rotating the knob bottom cover 180, thereby improving the accuracy of adjusting the exposed length of the lipstick core.

[0066] In the embodiment of the utility model, the connecting pipe 290 and the inner wall of the second chamber 190 form an annular mounting chamber 300, and the lower end face of the limiting plate 110 is formed with a limiting ring 310 that rotates and cooperates in the annular mounting chamber 300.

[0067] The design of the annular mounting chamber 300 and the limiting ring 310 ensures the accurate positioning of the screw lifting rod 170 in the knob bottom cover 180, preventing it from shifting or shaking during use, thereby enhancing the stability and reliability of the overall structure.

[0068] The presence of the limiting ring 310 helps to evenly distribute the force on the annular mounting chamber 300, reducing the risk of structural damage.

[0069] The cooperation of the annular mounting chamber 300 and the limiting ring 310 can compensate for manufacturing tolerances to some extent, ensuring good cooperation even in the presence of slight deviations in part dimensions, thereby improving the reliability and consistency of the product.

[0070] The close cooperation between the annular mounting chamber 300 and the limiting ring 310 can block external dust and moisture from entering the internal structure to some extent, protecting the internal components from contamination and prolonging the service life of the product.

[0071] In the embodiment of the utility model, at least two first elastic adjustment grooves 320 are uniformly and circumferentially provided on the side wall of the connecting pipe 290.

[0072] The first elastic adjustment grooves 320 allow the connecting pipe 290 to expand or contract to some extent, which helps to adapt to different diameter components, improving the compatibility and versatility of the product.

[0073] Since the connecting pipe 290 has a certain elasticity, it can automatically adjust the center position during installation, ensuring good alignment with other components and reducing assembly errors.

[0074] The design of the first elastic adjusting groove 320 makes the connecting pipe 290 easier to install and disassemble, especially when the internal components need to be replaced or maintained, providing greater convenience;

[0075] Reducing assembly difficulty: the elastic properties of the connecting pipe 290 reduce the requirement for assembly accuracy, ensuring good assembly results even in slight deviations, simplifying the quality control link in the production process.

[0076] In the embodiment of the utility model, the upper end of the knob bottom cover 180 is evenly provided with a plurality of second elastic adjusting grooves 330 along the circumference;

[0077] The design of the second elastic adjusting groove 330 makes the installation of the knob bottom cover 180 into the lower chamber 130 smoother, and at the same time, the first annular protrusion 360 better elastically rotates and fits in the first annular mounting groove 340, making the installation of the knob bottom cover 180 in the lower chamber 130 more stable.

[0078] In the embodiment of the utility model, the inner wall of the lower chamber 130 is provided with a first annular mounting groove 340 and a second annular mounting groove 350, the first annular mounting groove 340 is close to the limiting plate 110, the second annular mounting groove 350 is close to the opening of the lower chamber 130, and the outer wall of the knob bottom cover 180 is formed with a first annular protrusion 360 and a second annular protrusion 370 which respectively rotate and fit in the first annular mounting groove 340 and the second annular mounting groove 350;

[0079] The installation of the knob bottom cover 180 in the lower chamber 130 is more stable;

[0080] The first annular mounting groove 340 and the second annular mounting groove 350 provide a clear rotation path for the knob bottom cover 180, ensuring that it can stably rotate along the predetermined track during operation, avoiding deviation or shaking, and enhancing the stability and reliability of the overall structure;

[0081] The existence of the two annular protrusions helps to evenly distribute the force on the corresponding annular mounting chamber 300, reducing the single-point force condition and reducing the risk of structural damage.

[0082] By providing the first annular mounting groove 340 and the second annular mounting groove 350 on the inner wall of the lower chamber 130, and forming the first annular protrusion 360 and the second annular protrusion 370 on the outer wall of the knob bottom cover 180 which respectively rotate and fit in the two annular mounting chambers 300, not only the stability and operation performance of the mechanical structure are enhanced, but also the assembly process is simplified, the durability and reliability of the product are improved, and a higher quality product experience is provided for the user.
