[0002] Lipstick can beautify lips, change the color of lips, make lips more vivid, fuller, and more beautiful. After applying lipstick, the whole person's complexion will be improved, and they will appear more refreshed. Some lipsticks also have moisturizing and nourishing effects, which can relieve problems such as dry lips and peeling. In order to facilitate the storage of lipstick, a shell is needed to store the lipstick paste.

[0003] In the existing lipstick shell design, only a single buckle structure is often used for connection. Such a design is prone to loosening or falling off when used for a long time or subjected to external force, affecting the user experience. At the same time, the material selection of some lipstick shells is not reasonable, which makes the shell itself prone to deformation or damage. Therefore, it is necessary to improve the existing lipstick shell design to improve its connection stability and durability. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Example 1

[0029] Reference Figure 1-Figure 5The housing comprises: a housing 1, a cover 2, a fixed housing 3, a first inner tube 8, a second inner tube 9, a mounting tube 7 and other components. A cover 2 is provided on the upper surface of the housing 1 to protect the lipstick paste from being contaminated or damaged. Inside the housing 1, a fixed housing 3 is installed by a rotation connection, so that the fixed housing 3 can rotate inside the housing 1, so that the user can adjust the extension length of the lipstick paste conveniently.

[0030] The fixed shell 3 is sequentially installed with a first inner tube 8, a second inner tube 9 and a mounting tube 7. The mounting tube 7 is used to fill the lipstick paste, and the user can push the mounting tube 7 by rotating the fixed shell 3 or the housing 1 to control the extension length of the lipstick paste.

[0031] In order to ensure a stable connection between the cover body 2 and the fixed shell 3, first clamping blocks 5 are fixedly connected to the inner walls of the four sides of the cover body 2, and a plurality of first clamping grooves 4 are arranged on the circumference of the fixed shell 3. When the cover body 2 is closed, the first clamping blocks 5 will cooperate with the corresponding first clamping grooves 4 to form a snap-on connection.

[0032] In addition, in order to further enhance the connection stability between the cover body 2 and the fixed shell 3, two sets of fixing components are also designed. These fixing components are respectively arranged between the fixed shell 3 and the cover body 2, and are mainly composed of a mounting groove 14, a second clamping block 6 and a matching block 15. The mounting groove 14 is located on the circumferential inner wall of the cover body 2, and the second clamping block 6 is fixedly connected to the circumferential outer wall of the fixed shell 3. When the cover body 2 is closed, the second clamping block 6 will enter the mounting groove 14 and match with the protrusion 16 on the matching block 15 to form another layer of snap-on connection.

[0033] A special sliding structure is adopted in the design of the mounting tube 7. Two symmetrically arranged bosses 10 are fixedly connected on the circumference of the mounting tube 7, and these bosses 10 can slide in the second slide groove 12 of the first inner tube 8 and the first slide groove 11 of the second inner tube 9. Such a design allows the mounting tube 7 to slide conveniently inside the first inner tube 8 and the second inner tube 9, thereby controlling the extension length of the lipstick paste.

[0034] In order to prevent the second inner tube 9 from shaking during use, a gear ring 13 is fixedly connected inside the shell 1. The gear ring 13 and the second inner tube 9 can cooperate with each other to enhance the stability of the overall structure.

[0035] In terms of material selection, high-toughness polyethylene material is selected to make the housing 1, the cover 2 and the fixed shell 3. This material not only has good toughness, but also is light in weight, resistant to falling and collision, and is very suitable for making the lipstick housing 1.

[0036] The present application can be used for lipstick shells, and can also be used in other fields applicable to the present application.

In order to increase the aesthetics and anti-slip properties of the lipstick shell 1, a knurled pattern is also provided on the outer wall of the fixed shell 3.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
