As a result, it can form a guide support for the lifting process of the door body, so that the door body can be stably lifted to the target position. Further, in order to further improve the accuracy of the door body moving path, the guide mechanism 210 in the present application also includes a guide roller 211, and the guide roller 211 is arranged on the side of the guide slope 212 close to the door body to be lifted, and the rolling direction of the guide roller 211 is consistent with the opening and closing direction of the door body. The guide roller 211 in this embodiment is connected to the guide slope 212 through a connecting shaft 213, and based on this double guide structure, the door body can stably realize the lifting movement process.

[0036] See also Figure 2 As shown, the moving assembly 200 also includes a connecting piece, one end of which is connected to the guide mechanism 210, and the other end is passed through the interior of the box 100 and connected to the extrusion block 230. In this embodiment, the two ends of the connecting piece are fixedly connected to the guide mechanism 210 and the extrusion block 230 respectively, and are passed through the top surface of the box 100. The extrusion block 230 is preferably an elastic element, which moves up and down with the interior of the box 100. The first limiting groove 231 is arranged above the second limiting groove 232. Further, the sliding groove in this embodiment includes a transition groove, a first limiting groove and a second limiting groove. The first limiting groove is located above the second limiting groove. The transition groove connects the first limiting groove and the second limiting groove. When the door body lifting structure is in In the normal state, the extrusion block squeezes the elastic member, and the other end of the connecting rod is inserted into the first limiting groove; when the door body lifting structure is in the working state, the elastic member pushes the extrusion block, and the other end of the connecting rod is inserted into the second limiting groove, wherein the first limiting groove 231 and the second limiting groove 232 are both configured as "V"-shaped grooves, specifically configured as guide grooves with a low center and high ends. This structure enables the connecting rod 300 to always be stably located at the center of the first limiting groove 231 or the second limiting groove 232 in a static state. Specifically, in order to conduct the moving path of the connecting rod 300, a transition groove 233 is also provided on the extrusion block 230, and the transition groove 233 connects the first limiting groove 231 and the second limiting groove 232. See for details. Figure 3 As shown, in this embodiment, two transition grooves 233 are symmetrically arranged between the first limiting groove 231 and the second limiting groove 232. The two transition grooves 233 respectively connect the two ends of the first limiting groove 231 and the second limiting groove 232. At the same time, the end of the second limiting groove 232 is inclined toward the end of the first limiting groove 231 to achieve a guiding effect on the moving path of the connecting rod 300.
