Connecting device for cabinet body and cabinet body
ActiveCN224187863UImprove experienceQuick and accurate installationDismountable cabinetsFurniture joiningMechanical engineeringPhysics
A connecting device for a cabinet body comprises a connecting device body, a first connecting plane is arranged on one side of the connecting device body, a second connecting plane and a third connecting plane are arranged on the other side of the connecting device body, a segment difference is arranged between the second connecting plane and the third connecting plane, and a connecting piece is arranged on the other side of the connecting device body. The first connecting plane is used for being detachably connected to the handle baffle, the second connecting plane and the third connecting plane are used for abutting against the cabinet body, and the connecting piece is used for being detachably connected to the cabinet body. Due to the fact that the section difference is formed between the second connecting plane and the third connecting plane, in the process of installing the handle baffle, the connecting device only needs to be simply turned over, and the first connecting plane corresponding to the second connecting plane or the third connecting plane corresponding to the thickness size of the handle baffle is aligned with the handle baffle. According to the design, not only is the installation process simplified, but also the adaptability of the product and the user experience are greatly improved.

Stirring device and stirrer
This utility model relates to the field of household appliance technology and discloses a stirring device and agitator. The stirring device includes a housing assembly, a stirring component, and a protective cover. The housing assembly has a stirring chamber inside and a through hole. The stirring component is disposed in the stirring chamber, and the driving end of the stirring component is used to connect to an external driving component through the through hole. The protective cover is located in the stirring chamber and is disposed on the stirring component. Its projection on the housing assembly covers the through hole. By setting the protective cover, when the stirring component is stirring materials in the stirring chamber, the splashing materials are blocked by the protective cover and cannot splash directly into the through hole, preventing the materials from accumulating and clumping in the through hole. It also prevents materials from splashing from the through hole to the outside of the housing assembly, keeping the outside of the housing assembly clean. The driving component outside the housing assembly is also less likely to be contaminated by materials. This not only facilitates daily cleaning and maintenance but also effectively reduces the failure rate of the driving component caused by material contamination.
