[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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 application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1

[0031] like Figures 1 - 6 As shown, this embodiment discloses an adjustable shell connection structure, including a shell member 2 and a cover member 3. The shell member 2 is broken from the middle to form an opening. The shell member 2 can be opened from the opening and the circumference of the shell member 2 is longer than the circumference of other parts connected to it. The shell member 2 can adapt to different installation tolerances. The cover member 3 is detachably connected to the opening of the shell member 2 to cover the opening to ensure the aesthetic appearance. The shell member 2 includes a shell 21 and a docking structure 28. The docking structure 28 is arranged on both side walls of the opening of the shell 21. A protrusion 23, a movable part 22 and a plurality of through grooves 26 are provided on the docking structure 28. The protrusion 23 is arranged on both side walls of the opening, and the movable part 22 is arranged below the protrusion 23 along the edge line of the opening. A plurality of through grooves 26 are arranged on the movable part 22. The cover member 3 is clamped on the shell 21 through the through grooves 26, which can compensate for manufacturing errors and ensure the overall aesthetics.

[0032] There is a gap between the movable parts 22 that is larger than the gap between the protruding parts 23 and is used for installing the covering member 3 .

[0033] Furthermore, a plurality of protrusions 24 are provided on the docking structure 28, and the plurality of protrusions 24 are arranged on the inner wall of the outer shell 2, and the protrusions 24 are arranged one by one on the side of the through groove 26 close to the opening, and the protrusions 24 abut against the buckles 32 on the cover part 3 to limit the movement of the cover part 3 along the shell 21, and the cover part 3 is connected with the shell 21 to form a whole.

[0034] Furthermore, the cover member 3 includes a cover plate 31 and a plurality of clips 32. The plurality of clips 32 are arranged on the inner wall surface of the cover plate 31. The clips 32 pass through the through grooves 26 and abut against the protrusions 24 to limit the movement of the cover plate 31. The cross-section of the clips 32 is L-shaped. After passing through the through grooves 26, the clips 32 abut against the protrusions 24, and the friction force generated by the abutting pressure fixes the cover member 3 relative to the outer shell member 2. After the installation is completed, the clips 32 cannot fall out due to the tension of the shell 21.

[0035] Preferably, the cover member 3 further includes reinforcing ribs 34, which are arranged on the cover plate 31 along its length direction. The cover plate 31 is arc-shaped, and the reinforcing ribs 34 are used to increase the strength of the cover plate 31 to prevent the cover plate 31 from being deformed and loosened when being snapped.

[0036] More preferably, a connecting portion 25 is further provided on the docking structure 28. The connecting portion 25 is arranged on the inner wall of the protruding portion 23. A through hole is provided on the connecting portion 25 for the connecting member 4 to pass through. The connecting portion 25 is formed by stamping the protruding portion 23, with simple forming and low manufacturing cost.

[0037] More preferably, the covering member 3 further includes a groove 33. The groove 33 is arranged on the outer side wall of the buckle 32. The groove 33 is used to improve the strength and elasticity of the buckle 32. When the buckle 32 is snapped onto the housing 21, the protrusion 24 deforms the buckle 32, and the force generated by the deformation is used to fix the cover plate 31.

[0038] More preferably, a curling structure 27 is provided on the outer housing member 2. The curling structure 27 is arranged on the outer edge line of the outer housing member 2. The curling structure 27 is formed by curling the edge portion of the housing 21. The thickness of the curling structure 27 is greater than that of the housing 21, so that the curling structure 27 can be snapped onto other structures. In addition, the curling structure 27 also improves the strength of the outer housing member 2. The curling structure 27 makes the edge of the outer housing member arc-shaped, preventing cuts and enhancing the safety of disassembly and assembly.

[0039] Embodiment 2

[0040] This embodiment also discloses a rice cooker, including an adjustable outer shell connection structure, a middle ring 1 and a bottom shell 5. The adjustable outer shell connection structure is arranged between the middle ring 1 and the bottom shell 5 and can be adapted to the middle ring 1 and the bottom shell 5 with different tolerances during installation, reducing the manufacturing difficulty and assembly time.

[0041] Furthermore, a connecting member 4 is further included. The connecting member 4 passes through the docking structure 28 to fix the outer housing member 2 on the middle ring 1 for fixing the outer housing member 2 and preventing the outer housing member 2 from shaking.

[0042] Preferably, the adjustable outer shell connection structure is detachably connected to the middle ring 1 and the bottom shell 5, facilitating installation and replacement.

[0043] The assembly process of the adjustable outer shell connection structure is as follows:

[0044] Take the housing 21 and sleuth it on the middle ring 1. Apply an external force from the opening of the housing 21 to align the protruding portion 23. Take the covering member 3 and align the buckle 32 with the through slot 26, then forcefully insert the covering member 3 into the opening of the housing 21. When installing the covering member 3, the movable portion 22 on the housing 21 moves towards the opening, reducing the distance between the two through slots 26, making it easier to install the covering member 3. After completion, take the bottom shell 5 and install it at the other end of the outer housing member 2. Fine-tune the left and right positions of the covering member 3 to complete the fixation of the covering member 3 and ensure the overall aesthetics of the outer housing member 2. Finally, install the top cover 6 on the middle ring 1 to complete the assembly of the rice cooker.

[0045] Based on the disclosure and teachings of the above specification, those skilled in the art to which the present utility model pertains can also make changes and modifications to the above embodiments. Therefore, the present utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present utility model should also fall within the protection scope of the claims of the present utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
