Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a shell structure. Background Technology

[0002] The rotary linear motion mechanism is widely used in the housing structure of daily necessities such as lipsticks, gel sticks, and solid glue sticks. This mechanism typically consists of a rotating base, a lifting platform with a guide key, and an outer casing. The lifting platform and the rotating base are threaded together, and the guide key on the lifting platform is embedded in an axial groove on the inner wall of the outer casing. When the user rotates the rotating base located at the bottom of the casing, the lifting platform moves linearly along the axial direction under the constraint of the guide key, thus achieving smooth material ejection and retraction. This type of mechanism has advantages such as compact structure, low cost, and controllable motion stroke, and is widely applicable to light-load consumer products.

[0003] However, existing rotary linear motion mechanisms typically have mechanical limit structures at both ends of the slide to prevent excessive travel of the lifting platform, which could lead to jamming or damage. While the limit design helps protect the structure, it also restricts the lifting platform's full range of motion, preventing it from reaching the theoretical top exit position. Consequently, material inside the housing often cannot be completely ejected. Users frequently need external tools to remove residual material, which is not only inconvenient but also negatively impacts user experience and material utilization. Utility Model Content

[0004] This invention provides a shell structure designed to solve the problem of difficult removal of residual materials.

[0005] The solution adopted by this utility model to solve its technical problem is: a shell structure, including a rotating base, a sleeve and a lifting platform, wherein the top of the rotating base is provided with an external thread, the lifting platform is provided with an internal thread that meshes with the external thread, and the sleeve is fixed to the top of the rotating base and sleeved on the outside of the lifting platform.

[0006] The outer wall of the lifting platform is provided with a guide key, and the inner wall of the sleeve is provided with a sliding groove. The guide key is slidably connected inside the sliding groove.

[0007] The sleeve is provided with a mounting shell on its outer side, and a spring piece is provided on the outer wall of the sleeve. The mounting shell is provided with a fixing groove that matches the spring piece, and the lifting platform is provided with a groove that matches the spring piece.

[0008] Furthermore, a protective shell is snapped onto the outside of the mounting shell.

[0009] Furthermore, the top of the mounting housing is provided with a protective cover.

[0010] The protective cover in this embodiment can be fixed to the top of the mounting shell by snap-fit, hinge, or magnetic attraction.

[0011] Furthermore, the mounting housing is provided with a transparent viewing window.

[0012] Furthermore, a limiting plate is detachably connected to the top of the mounting shell, and the limiting plate is provided with openings.

[0013] Furthermore, a reflector is provided on the outer side of the protective shell.

[0014] This embodiment also provides a packaging shell for a body deodorant cream, wherein the packaging shell adopts the above-described shell structure.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] 1. In this embodiment, the outer side of the sleeve is provided with a mounting shell, the outer wall of the sleeve is provided with a spring piece, the mounting shell is provided with a fixing groove that matches the spring piece, and the lifting platform is provided with a groove that matches the spring piece. With the above design, when the user rotates the rotating base, as long as the spring piece does not correspond to the position of the groove on the lifting platform, the wall of the lifting platform can push the spring piece to one side of the fixing groove, so that the spring piece is engaged in the fixing groove. At this time, the mounting shell and the sleeve are in a fixed state.

[0017] When the spring corresponds to the groove on the lifting platform, the spring is not pushed by the lifting platform wall. Under the action of the restoring force, it enters the groove, thereby releasing the fixed state of the sleeve and the mounting shell, so that the sleeve and the mounting shell can be separated, making it convenient for the user to use the remaining material on the lifting platform.

[0018] 2. The mounting housing is equipped with a transparent viewing window, which allows users to visually check the remaining material inside the housing from the outside.

[0019] 3. A limiting plate is detachably connected to the top of the sleeve. The limiting plate is provided with an opening. With the above design, the user can squeeze the material in the shell through the opening on the limiting plate to prevent excessive material consumption and large-area contamination.

[0020] 4. A reflector is provided on the outside of the protective case. With the above design, when the material inside the case is applied to the body, the user can check the application of the material to the body through the reflector.

[0021] The above description is merely an overview of the technical solution of this utility model.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1 to 3 As shown, a housing structure includes a rotating base 1, a sleeve 2, and a lifting platform 3. The rotating base 1 has an external thread on its top, and the lifting platform 3 has an internal thread that meshes with the external thread. The sleeve 2 is fixed to the top of the rotating base 1 and sleeved on the outside of the lifting platform 3. The outer wall of the lifting platform 3 has a guide key 31, and the inner wall of the sleeve 2 has a groove 21. The guide key 31 is slidably connected inside the groove 21.

[0030] like Figure 2As shown, in this embodiment, the sleeve 2 has a through hole in the middle for the lifting platform 3 to pass through. A mounting shell 4 is snapped onto the outer side of the sleeve 2. A spring piece 22 is provided on the outer wall of the sleeve 2. The spring piece 22 is made of an elastic material and has elastic deformation capability. The mounting shell 4 has a fixing groove 41 that matches the spring piece 22. In this embodiment, the spring piece 22 is pushed into the fixing groove 41 by the wall of the lifting platform 3 to achieve the fixation of the mounting shell 4 and the sleeve 2.

When the user controls the lifting platform 3 to descend to its lowest position by rotating the base 1, the spring piece 22 corresponds to the position of the groove 32. Under the action of elastic restoring force, it automatically springs back into the groove 32, thereby releasing the snap-fit ​​between the spring piece 22 and the fixing groove 41, and unlocking the mounting shell 4 and the sleeve 2. At this time, the user can directly pull out the mounting shell 4 and the protective shell 5 from the sleeve 2 and directly use the remaining materials on the lifting platform 3.

[0033] It should be noted that the fixing groove 41 in this embodiment can be either a groove or a hole.

[0034] In this embodiment, the mounting shell 4 is snapped onto the outer side of the protective shell 5. Specifically, the mounting shell 4 has a snap-fit ​​protrusion inside, and the protective shell 5 has a snap-fit ​​groove outside. The snap-fit ​​protrusion is snapped onto and adapted to the inside of the snap-fit ​​groove.

[0035] In this embodiment, the top of the mounting shell 4 is provided with a protective cover 6. Optionally, the protective cover 6 can be fixed to the top of the mounting shell 4 by snap-fit, hinge or magnetic attraction.
