Bottle frame assembly, door assembly and refrigeration equipment

The invention relates to the technical field of refrigeration, and provides a bottle frame assembly, a door assembly and refrigeration equipment. The bottle frame assembly comprises two oppositely-arranged mounting bases, sliding grooves extending in the height direction of the mounting bases are formed in the mounting bases, and a plurality of inserting grooves sequentially formed in the height direction of the mounting bases are formed in the edges of the mounting bases. Inserting blocks matched with the inserting grooves in an inserted mode are formed on the side wall of the bottle frame. The bottle frame can be switched between a vertical locking state in which the insertion blocks are inserted into the insertion grooves and an inclined unlocking state in which the insertion blocks are separated from the insertion grooves; the first pulleys are rotatably mounted on the side wall of the bottle frame and located above the corresponding insertion blocks; the first pulleys are embedded in the corresponding sl
