Description

Technical Field

[0001] The utility model relates to the technical field of lipsticks, in particular to a middle bundle core component that is easy to use. Background Art

[0002] The middle bundle core refers to the lipstick tube used to hold lipstick. The middle bundle core includes components such as beads, spirals, and middle sections. The beads are a cylinder with one end open and the other end closed for holding cosmetics, and are connected to the transmission rod. The spiral is a hollow tubular structure. The transmission rod extends into the spiral and cooperates with its thread to drive the cylinder to reciprocate along the axial direction. The middle section is a hollow tubular structure, which is inserted into the outside of the spiral and fixed relative to the spiral axial direction. There are circumferentially arranged convex ribs between the two. The middle section has a through hole for the transmission rod to pass through and limit the rotation of the beads relative to it. This design can provide a damping feeling during rotation, thereby enhancing the user experience.

[0003] Traditional lipstick tubes are generally controlled by holding the outer spiral tube and manually turning the middle section at the bottom to control the internal beads to move up and down, thereby driving the lipstick to extend out of the spiral tube and the middle section. Therefore, in actual use, the top of the lipstick tube is also equipped with a cap to ensure the relative stability of the internal environment of the lipstick tube and reduce the phenomenon of dust and impurities entering the lipstick tube. However, the cap is generally configured separately, pulled out when in use, and inserted when not in use. Therefore, there are many inconveniences in actual use, and the cap may be lost, which is not convenient for practical application. Utility Model Content

At this time, continue to rotate until the bottom of the bead 2 squeezes the bottom plate 9, causing the bottom plate 9 to move downward, driving the connecting rod 8 to move downward synchronously, and the connecting rod 8 drives the cover plate 6 to rotate downward through the linkage mechanism until the cover plate 6 completely covers the top of the middle section 5, which is convenient for operation.

[0028] Furthermore, the lipstick body 1 is inserted into the bead 2, the transmission rod 3 is fixedly installed on the side wall of the bead 2, the bead 2 is arranged inside the spiral tube 4, the inner wall of the spiral tube 4 is provided with a threaded groove, the port of the transmission rod 3 is arranged inside the threaded groove, the middle section 5 is inserted into the spiral tube 4, a long hole is opened on the surface of the middle section 5, the transmission rod 3 passes through the long hole, the middle section 5 passes through the spiral tube 4 downward, and the surface of the middle section 5 near the bottom is evenly provided with convex ribs.

[0029] Furthermore, the linkage mechanism includes a rotating shaft 14, a groove is opened on the surface of the cover 6, the rotating shaft 14 is fixedly installed inside the groove, a gear 13 is fixedly sleeved on the surface of the rotating shaft 14, two fixed rods 15 are fixedly installed on the top of the middle section 5, the cover 6 is rotatably connected through the rotating shaft 14 and the two fixed rods 15, and a rack 12 is fixedly installed on the side wall of the connecting rod 8 near the top, the rack 12 and the gear 13 are meshed to achieve a state in which the rack 12 moves upward and drives the cover 6 to flip upward through the gear 13 and the rotating shaft 14. When the linkage mechanism is in use, the connecting rod 8 will drive the rack 12 to move, the rack 12 will drive the gear 13 to move, and the gear 13 will drive the rotating shaft 14 and the cover 6 to move synchronously, thereby achieving the purpose of flipping the cover 6 upward and covering it downward.

[0030] Furthermore, a sealing gasket 7 is fixedly mounted on the surface of the cover plate 6 , and the sealing performance of the cover plate 6 to the interior of the center section 5 can be enhanced by providing the sealing gasket 7 .

[0031] Furthermore, an elastic block 11 is fixedly installed on the surface of the cover 6 at a position away from the rotating shaft 14, and a slot matching the size of the elastic block 11 is opened at the top of the middle section 5 away from the fixing rod 15. By setting the elastic block 11, when the lipstick is used more, the beads 2 do not need to be completely moved to the lowest point of the middle section 5. At this time, the beads 2 will not exert pressure on the bottom plate 9, so the cover 6 cannot be used in a linked manner. At this time, the cover 6 can be manually rotated, and the cover 6 can use the rotating shaft 14 to drive the gear 13 to rotate synchronously, and the gear 13 drives the rack 12 to move downward until the elastic block 11 on the surface of the cover 6 is engaged with the slot, and the sealing of the top of the middle section 5 can also be achieved. The cover 6 can also be manually opened upwards, and the cover 6 can be operated separately without moving the bottom plate 9, thereby enhancing the flexibility of operation.

[0032] Furthermore, a through groove 17 is formed on the inner wall of the middle section 5 so that the vertical groove 16 and the interior of the middle section 5 are connected to each other.

[0033] In summary, when the lipstick body 1 needs to be rotated out for use, just hold the spiral tube 4 and then manually rotate the middle section 5. At this time, the internal beads 2 will move upwards using the transmission rod 3, thereby driving the lipstick body 1 to move upward synchronously. When the middle section 5 moves upward, the pressure on the bottom plate 9 will gradually disappear, so that the bottom plate 9 will gradually move upward under the action of the spring 10, thereby driving the connecting rod 8 to move upward synchronously, and the connecting rod 8 drives the rack 12 to move upward, and the rack 12 drives the gear 13 to rotate, thereby driving the rotating shaft 14 and the cover plate 6 to rotate upward synchronously, and then the cover plate 6 will automatically open before the lipstick body 1 extends out of the spiral tube 4 and the middle section 5, and there is no need to configure a lid for use. When the lipstick is used up, hold the spiral tube 4 and manually rotate the middle section 5, so that the beads 2 drive the lipstick body 1 to move downward until the lipstick body 1 is completely hidden in the middle section 5. At this time, continue to rotate until the bottom of the beads 2 squeezes the bottom plate 9, causing the bottom plate 9 to move upward. The cover plate 6 is moved downward, driving the connecting rod 8 to move downward synchronously, and the connecting rod 8 drives the rack 12 to move downward synchronously, and the rack 12 drives the gear 13 and the rotating shaft 14 to rotate synchronously, so that the cover plate 6 rotates downward until the cover plate 6 completely covers the top of the middle section 5, which is convenient for operation and use. The sealing performance of the cover plate 6 to the inside of the middle section 5 can be enhanced by setting the sealing gasket 7. By setting the elastic card block 11, when the lipstick is used more, the beads 2 do not need to be completely moved to the lowest point of the middle section 5. At this time, the beads 2 will not exert pressure on the bottom plate 9, so the cover plate 6 cannot be used in linkage. At this time, the cover plate 6 can be manually rotated, and the cover plate 6 can use the rotating shaft 14 to drive the gear 13 to rotate synchronously, and the gear 13 drives the rack 12 to move downward until the elastic card block 11 on the surface of the cover plate 6 is engaged with the card slot, which can also achieve sealing on the top of the middle section 5. The cover plate 6 can also be manually directly opened upward, and the cover plate 6 can be operated separately without moving the bottom plate 9, thereby enhancing the flexibility of operation.
