Description

Technical Field

[0001] The utility model relates to the technical field of middle beam cores, in particular to a rabbit ear fork red aluminum middle beam core. Background Art

[0002] Lipstick is the general term for all lip makeup, including lip balm, lip stick, lip gloss, lip glaze, etc. It can make the lips rosy and shiny, moisturize and protect the lips, increase facial beauty and correct the lip contour. It is a product that has a supporting effect. It is one of the must-have beauty cosmetics for women.

[0003] The finished lipstick tube usually includes a cap, a center bundle core and an outer base. The center bundle core includes a center bundle portion, a spiral portion, a fork portion and a bead portion which are sequentially arranged from the outside to the inside. The bead portion is arranged on the inner side of the fork portion, and the bead portion is used to place the lipstick paste. The assembled center bundle core is inserted into the outer base of the lipstick tube and then matched with the cap to assemble the finished lipstick tube. Therefore, the center bundle core becomes an important core component of the lipstick tube. The center bundle core mainly includes an aluminum center bundle, a spiral tube, beads and a fork.

[0004] For example, the existing patent announcement number CN209284448U provides a rabbit-ear fork red aluminum middle bundle core. The device interferes with the spiral in a point manner, which can effectively control the feel of rotation, so that the user can better use the device. At the same time, the device can directly drive the first fixed block and the second fixed block to move through the rotating cylinder. It has a simple structure and low cost, and can be better promoted.

[0005] However, the device is only suitable for effectively controlling the feel of rotation so that the user can better use the device.

[0006] In the existing rabbit ear fork lipstick aluminum center bundle core, the beads provide the rabbit ears to move inside the fork. When the lipstick moves up and down along the fork, its surface is easily in friction contact with the inner surface of the fork, causing wear of the lipstick surface. No interval is set between the fork surface and the lipstick. At the same time, during the rotation of the fork, the fork and the spiral tube rotate relative to each other, resulting in greater friction. Long-term forward and reverse rotation will cause the gap between the fork and the spiral tube to be too large, causing the lipstick to shake, and the beads and lipstick are relatively loose during the lifting and lowering process, and the rotation feel is poor. Utility Model Content

[0007] The utility model aims to provide an aluminum middle bundle core of a rabbit ear fork lipstick to solve the problem that the fork and the spiral tube rotate relative to each other, have large friction, and long-term forward and reverse rotation will cause the gap between the fork and the spiral tube to be too large, causing the lipstick to shake.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rabbit-ear fork-mouth red aluminum middle bundle core, comprising an aluminum middle bundle, the interior of the aluminum middle bundle is connected with a spiral tube, the interior of the spiral tube is provided with a fork, and the interior of the fork is installed with beads.

[0011] Preferably, the inner surface of the spiral tube is provided with a spiral groove, and the side of the bead is fixed with a rabbit ear.

[0012] Preferably, the rabbit ear passes through the guide groove, and the outer end of the rabbit ear is inserted into the spiral groove.

[0013] Preferably, a lipstick plug rod is fixed in the middle of the top of the bead, a protective ring is fixed to the edge of the top of the bead, a sealing ring is adhered to the outer surface of the protective ring, and the outer side of the sealing ring is in sliding contact with the inner surface of the fork.

[0014] Preferably, a first buffer pad is adhered to the top end of the guide groove, and a second buffer pad is adhered to the bottom end of the guide groove.

[0015] Preferably, a ball is installed at the bottom end of the gap between the spiral tube and the fork, and the surface of the ball is wrapped with a wear-resistant sleeve.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model installs a ball at the bottom end of the gap between the spiral tube and the fork, and wraps a wear-resistant sleeve on the surface of the ball. The wear-resistant sleeve is made of wear-resistant rubber material and has a certain elasticity. In this way, during the repeated forward and reverse rotation of the fork, a certain distance is provided between the fork and the spiral tube due to the arrangement of the ball, thereby reducing friction and wear, always maintaining a certain gap interval, and maintaining stable relative rotation between the fork and the spiral tube. After a long time, the fork will not become loose and has a good rotation feel.

[0018] 2. The utility model provides a first buffer pad and a second buffer pad at the top and bottom of the guide groove on the surface of the fork, respectively. In this way, when the bead moves up and down inside the fork along the guide groove, excessive movement between the bead and the fork is reduced, and vibration and impact are reduced, so that the lipstick can stably enter and exit the fork. In addition, a protective ring and a sealing ring are provided at the top edge of the bead, and the sealing ring is in close contact with the inner surface of the fork. In this way, a gap between the lipstick and the fork can be maintained, reducing friction and wear between the lipstick and the fork, keeping the surface of the fork clean, and reducing vibration and impact on the lipstick caused by falling.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The rabbit-ear fork-mouth red aluminum center bundle core shown in the figure includes an aluminum center bundle 5, which is a cylindrical structure and is slidingly connected to the base 1, the connecting column 2 and the fork 7; the interior of the aluminum center bundle 5 is connected with a spiral tube 8, which is fixedly connected to the aluminum center bundle 5, and is relatively rotationally connected to the fork 7, and is axially fixed to the fork 7.

[0030] A fork 7 is provided inside the spiral tube 8, and a bead 11 is installed inside the fork 7. The bead 11 is slidably installed inside the fork 7 to drive the lipstick to move up and down; a connecting column 2 is fixed to the bottom end of the fork 7, and a base 1 is installed outside the connecting column 2. By rotating the base 1 and the connecting column 2, the fork 7 is driven to rotate.

[0031] A guide groove 9 is provided on the surface of the fork 7 . The guide groove 9 is vertically arranged and has a length not greater than the height of the fork 7 . The bead 11 is used to move up and down along the guide groove 9 through the rabbit ear 12 . The bead 11 is connected to the fork 7 by a sliding installation.

[0032] A spiral groove 4 is formed on the inner surface of the spiral tube 8, and a rabbit ear 12 is fixed on the side of the bead 11. The rabbit ear 12 slides through the guide groove 9, and the outer end of the rabbit ear 12 is inserted into the spiral groove 4. During the relative rotation of the spiral tube 8 and the fork 7, the bead 11 moves up and down along the guide groove 9.

[0033] A lipstick plug-in rod 3 is fixed in the middle of the top of the bead 11 for fixing the lipstick; a protective ring 10 is fixed to the top edge of the bead 11, and the protective ring 10 is a circular structure. A sealing ring 13 is adhered to the outer surface of the protective ring 10, and the outer side of the sealing ring 13 is in sliding contact with the inner surface of the fork 7. The gap between the inner surface of the lipstick and the fork 7 is set by the protective ring 10 and the sealing ring 13, so as to reduce the friction and wear between the lipstick and the inner surface of the fork 7.

[0034] A first buffer pad 6 is adhered to the top of the guide groove 9, and a second buffer pad 14 is adhered to the bottom of the guide groove 9. Both the second buffer pad 14 and the first buffer pad 6 are made of elastic rubber material, which can reduce the vibration and impact between the rabbit ear 12 and the fork 7 during the up and down movement.

[0035] A ball 15 is installed at the bottom end of the gap between the spiral tube 8 and the fork 7, and the surface of the ball 15 is wrapped with a wear-resistant sleeve 16. In this way, the spiral tube 8 and the fork 7 are installed and connected at intervals, and are set at intervals by the ball 15 and the wear-resistant sleeve 16 to reduce friction and wear between the fork 7 and the threaded tube 8.

[0036] The red aluminum middle bundle core of the rabbit ear fork mouth is used as follows: a ball 15 is installed at the bottom end of the gap between the spiral tube 8 and the fork 7, and a wear-resistant sleeve 16 is wrapped on the surface of the ball 15. The wear-resistant sleeve 16 is made of wear-resistant rubber material and has certain elasticity and wear resistance.

[0037] In this way, during the repeated forward and reverse rotation of the fork 7, during the relative rotation between the fork 7 and the spiral tube 8, a certain interval is provided due to the arranged ball 15, thereby reducing the friction and wear between the fork 7 and the spiral tube 8, always maintaining a certain gap interval, and maintaining stable relative rotation between the fork 7 and the spiral tube 8, so that the fork 7 and the threaded tube 8 will not become loose over time and have a good rotation feel.

[0038] A first buffer pad 6 and a second buffer pad 14 are respectively provided at the top and bottom ends of the guide groove 9 opened on the surface of the fork 7. In this way, when the bead 11 moves up and down inside the fork 7 along the guide groove 9, excessive movement between the bead 11 and the fork 7 is reduced, and vibration and impact are reduced, thereby keeping the lipstick stable in and out of the fork 7.

[0039] Moreover, a protective ring 10 and a sealing ring 13 are arranged at the top edge of the bead 11, and the sealing ring 13 is in close contact with the inner surface of the fork 7. In this way, a gap can be maintained between the lipstick and the fork 7, reducing the friction and wear between the lipstick and the fork 7, keeping the inner surface of the fork 7 clean, and reducing the vibration and impact on the lipstick caused by falling to the ground.
