[0002] In modern living environments, emphasis is placed on storage and comfort. In some densely populated cities and countries, storage and organization are not limited to daily utensils. Moreover, due to the limited living space in some current living environments, the living area is very compact. Therefore, people usually arrange their living environments better in limited spaces. A bed is one of the essential household items in people's home lives. However, usually, a bed occupies a large floor area and often takes up a significant amount of living space. Thus, by improving the usage method of the bed to obtain more activity space, the foldable wall bed industry has emerged.

[0003] Please refer to Figure 1 , which is a schematic structural diagram of a current wall bed; as shown in the figure, the structure of the current wall bed S usually consists of a wall bed cabinet and a wall bed body. One side of the wall bed body is rotatably connected to the wall bed cabinet through a connecting rod assembly S11 provided in the wall bed cabinet, and the other side of the wall bed body can rotate around its rotatable connection side with the wall bed cabinet to realize the unfolding and storage actions of the wall bed body. During the implementation of the present application, the applicant found that there is no self-locking structure between the wall bed cabinet and the wall bed body of the current wall bed S. When the wall bed cabinet is not firmly installed or is loose, there may be a risk that the wall bed cabinet topples in the direction of the wall bed body (for example, the inclined direction shown in Figure 1 ), resulting in a great safety hazard for the wall bed S. Summary of the Utility Model

[0004] The embodiments of the present application provide a wall bed with a self-locking function, which solves the problem that the wall bed cabinet of the current wall bed topples due to insecure installation or looseness.
