Description

Technical Field

[0001] The utility model relates to the technical field of lipstick tubes, and more specifically to a replaceable lipstick tube. Background Art

[0002] With the development of market demand and environmental protection concepts, in the prior art, lipstick tubes also tend to use replaceable structures. The structure of the lipstick tube includes a middle bundle and a bottom shell. The middle bundle and the bottom shell are mostly integrally formed or non-detachable structures. The replacement is only to replace the inner bead installed inside the middle bundle (the part where the lipstick body is installed). However, since the lipstick body itself is relatively fragile and easily broken during transportation, the replacement parts need to be specially packaged and protected for the lipstick body during packaging, which wastes packaging materials. In addition, when replacing the inner bead, it is inevitable that the lipstick body will be contacted, causing the lipstick body to be contaminated by hands. Therefore, a technical solution is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment 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 making creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment discloses a replaceable lipstick tube, including a bottom shell 1, an inner bead 2, a middle bundle 3, a bottom cover 4, an outer cover 5, and a lubricating sheet 6. The inner bead 2 is installed in the middle bundle 3, and the inner bead 2 is partially located in the middle bundle 3. The inner bead 2 includes an upwardly open installation space 21 for installing the lipstick body, and the installation space 21 is always located inside the middle bundle 3. The lower end of the inner wall of the middle bundle 3 is provided with a second guide block 32, and the outer wall of the inner bead 2 is provided with a guide track 25 capable of accommodating the movement of the second guide block 32. The guide track 25 includes a first slide groove 251 and a second slide groove 252, the first slide groove 251 extends along the length direction of the inner bead 2, the upper end of the first slide groove 251 is connected to the upper end surface of the inner bead 2, the lower end of the first slide groove 251 is connected to the second slide groove 252, the second slide groove 252 extends downward in a spiral around the outer peripheral wall of the inner bead 2, when the inner bead 2 and the middle bundle 3 are installed, the inner bead 2 is inserted into the middle bundle 3 from the lower end, the second guide block 32 of the middle bundle 3 is correspondingly inserted into the upper end opening of the first slide groove 251, and the inner bead 2 is pushed into the middle bundle 3 so that the second guide block 32 is located at the lower end of the first slide groove 251.

[0024] like Figure 1 As shown, the bottom cover 4 is installed on the lower end opening of the bottom shell 1, and the bottom cover 4 is connected to the bottom shell 1 by a buckle. The bottom surface of the bottom cover 4 is provided with an upwardly concave groove 43, and a pull plate 431 is provided in the groove 43. The pull plate 431 extends downward, and the lower end surface of the pull plate 431 is flush with the bottom surface of the bottom cover 4. After the lipstick body on the inner bead 2 is used up, the pull plate 431 is pulled downward to disengage the buckle between the bottom cover 4 and the bottom shell 1, and the middle bundle 3 and the inner bead 2 are taken out, and the new middle bundle 3 and the inner bead 2 are installed, and then the bottom cover 4 is buckled into the bottom shell 1.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the inner bead 2 includes a guide space 22, which is the part of the inner bead 2 that opens toward the bottom cover 4, the middle bundle 3 is partially located in the bottom shell 1, and the bottom cover 4 includes a second ring plate 42, which extends toward the middle bundle 3, and the second ring plate 42 is partially located inside the guide space 22 of the inner bead 2, and the outer wall of the second ring plate 42 contacts the side wall of the guide space 22, and the outer wall of the second ring plate 42 is provided with a guide groove 421, and the guide groove 421 extends along the length direction of the second ring plate 42, and the lower end of the inner wall of the inner bead 2 is provided with a first guide block 23 corresponding to the guide groove 421, and the inner bead 2 can move up and down along the second ring plate 42, and when the middle bundle 3 is rotated, the second guide block 32 located at the bottom end of the first slide groove 251 moves along the second slide groove 252, so that the inner bead 2 can move up and down along the second ring plate 42, so that the lipstick body can extend out of the upper end of the middle bundle 3 for use or rotate in reverse to retract the lipstick body into the middle bundle 3.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, a stop shoulder 24 is provided at the lower end of the outer wall of the inner bead 2. When the inner bead 2 is raised to the highest point by rotating the middle beam 3, the stop shoulder 24 presses against the lower end of the middle beam 3 to limit the highest point of the inner bead 2.

[0027] like Figure 4As shown, the guide rail 25 includes a limiting groove 253, which is located at the connection between the first slide groove 251 and the second slide groove 252. The limiting groove 253 is horizontally arranged and opposite to the direction of the second slide groove 252. The lower end surface of the limiting groove 253 is provided with a first protrusion 2521, and the second guide block 32 can pass over the first protrusion 2521 and snap into the limiting groove 253. The second guide block 32 is provided with a snap-in groove 321, and the lower end surface of the limiting groove 253 is provided with a second protrusion 2522 corresponding to the snap-in groove 321. When the second protrusion 2522 is snapped into the snap-in groove 321, the first protrusion 2521 abuts against the peripheral side wall of the second guide block 32. When the rotation is in progress, the limiting groove 253 is provided with a first protrusion 2521. When the middle bundle 3 is in the process of being rotated, the second guide block 32 located at the bottom of the first slide groove 251 moves toward the direction of the limiting groove 253. After the second guide block 32 passes over the first protrusion 2521, the slot 321 at the lower end of the second guide block 32 is clamped with the second protrusion 2522. At the same time, the second protrusion 2522 abuts against the outer wall of the second guide block 32. The second protrusion 2522 has a certain blocking effect on the second guide block 32, which can limit the rotation direction between the middle bundle 3 and the inner bead 2 to prevent the two from loosening during replacement. At the same time, it can fix the inner bead 2 when it reaches the lowest end position to prevent the inner bead 2 from loosening in the middle bundle 3.

[0028] like Figure 1 As shown, the bottom cover 4 includes a first ring plate 41, which extends toward the middle beam 3. The middle beam 3 includes a retaining ring 31. The retaining ring 31 is located at the portion of the middle beam 3 located in the bottom shell 1. The upper end of the first ring plate 41 abuts against the upper end surface of the lubricating sheet 6 against the retaining ring 31. The upper end surface of the lubricating sheet 6 abuts against the retaining ring 31. The lubricating sheet 6 increases the contact area between the first ring plate 41 and the retaining ring 31. At the same time, the lubricating sheet 6 is coated with lubricating oil to play a lubricating role. At the same time, the lubricating sheet 6 can also increase the feel of the rotating middle beam 3 and will not cause the middle beam 3 to rotate too fast. The bottom shell 1 is provided with a convex ring 11, which is located at the upper end opening of the bottom shell 1. The convex ring 11 covers a portion of the middle beam 3. The outer cover 5 is buckled with the convex ring 11. The outer cover 5 is fixedly installed on the bottom shell 1. The outer cover 5 covers the portion of the middle beam 3 located outside the bottom shell 1.
