[0002] In order to improve the space utilization, people usually install wall-mounted racks in bathrooms, kitchens and rooms with small storage space. Existing wall-mounted racks are of fixed type and foldable type. For example, CN212939327U is a foldable wall-mounted rack and CN217851969U is a foldable wall-mounted rack. When not in use, the rack is folded up and attached to the wall, which occupies a small space. When in use, it is unfolded and can be used for temporary storage and placement. However, in order to ensure the stability of the foldable racks, inclined support rods are required to be provided above or below the storage board for support, which makes it inconvenient to fold and use. Moreover, when in the folded state, whether it is the fixed board, the storage board or the support frame, it is exposed and protrudes from the wall, which is not convenient to fold and looks abrupt, which is not conducive to the aesthetic feeling of the home.

[0006] Further improvements are that the guide support hole, guide limit hole and plug-in hole are coaxially arranged, the axial dimension of the guide support hole is larger than the axial dimension of the guide limit hole and the first guide connecting block and the second guide connecting block, and the radial dimension of the plug-in hole and the protrusion is larger than the radial dimension of the guide support hole.

[0007] A further improvement is that the plug-in hole and the protrusion are configured as a circular structure, a polygonal structure or a special-shaped structure.

[0008] A further improvement is that the connecting back plate is configured as an integral sheet metal structure.

[0009] Further improvements are: the support plate includes a fixed plate body, a connecting cross plate vertically arranged at the upper and lower ends of the fixed plate body and supporting lugs symmetrically arranged on both sides of the fixed plate body, and the lower ends of the supporting lugs are provided with a yielding groove; the bearing plate includes: a bottom plate, side plates arranged around the bottom plate and an inner edge structure bent horizontally inward along the side plates, the bottom plate, side plates and inner edge structure form an open cavity structure that surrounds the support plate; one end of the flipping mechanism is fixedly connected to the supporting lug, and the other end is rotatably arranged at one end of the side plate of the bearing plate close to the vertical wall.

[0010] A further improvement is that the flipping mechanism includes: a rotating shaft symmetrically arranged on both sides of the supporting plate, a rotating bracket rotatably arranged on the rotating shaft, a locking nut connected to the end of the rotating shaft, and an elastic buffer structure and a gasket arranged between the rotating bracket and the locking nut, and the other end of the rotating bracket is fixedly connected to the supporting lug.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present application provides a shelf with a support plate, a load-bearing plate and a flip mechanism, and provides a fixed connection back plate on the wall. The rear side of the connection back plate is fixed to the wall by gluing, thereby increasing the contact surface between the connection back plate and the wall, thereby improving the convenience, speed and firmness of the installation of the connection foundation. By providing two or more buckle support structures with relative sliding buckles between the support plate and the connection back plate, the overall load-bearing capacity, stability and installation convenience of the support plate and the load-bearing plate are increased, and no additional support rods are required to improve the overall stability, thereby reducing the exposure of components and saving costs. By arranging a flip structure at the bottom of the support plate to connect the bearing plate, the bearing plate can cover the support plate and the flip structure as a whole in its open cavity structure after flipping and folding, and can accommodate the placed items to prevent them from falling when flipped to a horizontal state for use; after flipping and folding, the inner edge structure is close to the wall, which plays a role of overall covering, hiding and shielding the support plate, effectively protecting the internal structure of the shelf, and having a good dust and dust prevention effect; at the same time, a support plate with upper and lower connecting horizontal plates and left and right supporting lugs is arranged, one end of the flip structure is fixedly connected to the supporting lug, and the bearing plate is rotated to a horizontal position, and the side edge and the inner folding edge structure on the inner side of the bearing plate abut against the connecting horizontal plate for support and limiting; the connection support of the bearing plate is firm and reliable, and the carrying capacity of the objects is increased; after flipping and folding and being close to the wall, decorative pictures can be pasted on the outer back of the bearing plate to play a role of space decoration, and can also be used for the decoration of household switch panels, and the applicability is relatively wide; the overall structure of the present application is simple and compact, and is convenient to fold, and will not be abrupt due to exposure and affect the beauty of the home.

[0014] Since the axial dimension of the guide support hole is larger than that of the guide limit hole, and the axial dimensions of the first guide connecting block and the second guide connecting block arranged on both sides of the protrusion are compatible with the guide limit hole, the first guide connecting block and the second guide connecting block have a guiding sliding distance between the guide support hole and the guide limit hole, and since: a guide cavity is provided between the protrusion and the connecting back plate, when the protrusion slides along the guide support hole to the first guide connecting block and the top of the guide support hole for support, the connection between the plug-in hole and the guide support hole slides into the guide cavity and is locked by the protrusion and will not fall off, thereby ensuring that the support plate and the connecting back plate are connected firmly and reliably by the buckle, while improving the bearing capacity of the lower load-bearing plate. This buckle structure is simple, the buckle connection operation is convenient, fast and reliable, and the stability is high. There is no need to add additional supporting structure to achieve the purpose of improving stability and bearing capacity, and at the same time it will not increase the folding space, thereby improving space utilization.

[0015] By arranging an elastic buffer structure between the rotating bracket and the locking nut, the elastic buffer structure has excellent elasticity, so that the load-bearing plate is more stable when unfolding and folding, reducing the impact force of folding and unfolding, and effectively preventing accidental damage.

[0016] By setting a flange limiter on the rotating shaft, the connection strength with the rotating bracket is increased while increasing the rotation friction to enhance the rotation damping and achieve a buffering effect. When the limit protrusion and the matching positioning groove are rotated, a certain step positioning effect is achieved under the action of the elastic buffer structure, thereby achieving different rotation angle limits.
