A module connection structure, a modular display frame for a buffet cart, and a buffet cart. The module connection structure is used to connect an upper module (11) and a lower module (12) which are stacked vertically. A top plate (121) of the lower module (12) is fixed with a nut socket (16), and a screw (13) corresponding to the nut socket (16) is inserted into a base plate (111) of the upper module (11). The screw (13) is screwed into the nut socket (16) to connect the upper module (11) and the lower module (12). At least two pairs of screws (13) and nut sockets (16) are provided between the upper module (11) and the lower module (12). The modular display frame (100) for a buffet cart comprises the aforementioned module connection structure, and adjacent modules stacked vertically are vertically connected by means of the module connection structure. The invention achieves an arrangement of multiple vertically stacked modules and connects the modules by dedicated screws and nut sockets, such that the vertically stacked modules allow display of food in a height direction, thereby enabling more food to be placed on a buffet cart, improving space utilization efficiency, and meeting a demand for holding more food.

The present utility model is applicable to the technical field of electric-heating insulation devices, and provides a wireless insulation board, comprising a shell, a panel, an electric heating component, and a battery power supply system. The panel is provided on the electric heating component, and covers the shell. The battery power supply system is embedded in the shell, and is electrically connected to the electric heating component. The wireless insulation board of the present utility model is provided internally with a battery power supply system that can supply power for the electric heating component and does not need a power line to connect to an external power source, and therefore, the wireless insulation board can be moved arbitrarily for use by a user in daily life or in occasions such as banquets. Furthermore, since the wireless insulation board no longer depends on a fixed power source, it is easy to carry and can be applied outdoors. In addition, the wireless insulation board has no power line extending beyond the insulation board, and therefore, the wireless insulation board can be widely embedded in different types of electric heating products.
Provided is a modular foldable buffet cart, comprising a foldable caster frame (100), a plurality of cooking modules (200), and decorative panels; the cooking modules (200) and decorative panels are detachably nested on the caster frame (100); the caster frame is internally provided with a power-supply connection cable (110); one end of the power-supply connection cable is serially connected to a plurality of frame sockets (120) used for connecting with the electrical power plugs of the cooking modules (200), and the other end is connected to a plurality of frame plugs (130) of a quantity matching that of the frame sockets (120) and used for connecting to an external power supply; the frame plugs (130) are fixed on said caster frame (100), and the frame plugs (130) are arranged inside the caster frame (100). In the buffet cart, the requirements of various cooking functions and changeability of outward appearance may be satisfied by changing the cooking modules (200), while it also facilitates the connection of the electrical power plugs of the cooking modules (200) to the frame sockets (120) on the caster frame; it has the advantages of interchangeability of tabletop devices and convenience in using tabletop devices for cooking.
