The invention discloses a tent framework capable of being folded and assembled and a tent thereof, and the tent framework comprises connecting heads and connecting rods, wherein each connecting head is provided with a connecting ring, more than two movable buckle pins rotating and sliding around the connecting ring are sheathed on each connecting ring, the movable buckle pins are in plug-in connection or cup joint with two ends of each connecting rod, a plurality of the connecting heads are taken as vertices respectively, and the connecting heads and the connecting rods are mutually connected for constituting tapered unit tent frameworks, wherein the bottom surface of each tapered unit tent framework is a polygon with more than three sides. The tapered unit tent frameworks are mutually combined, expanded and connected, and the connecting rods are arranged at the tapered top parts of the connected tapered unit tent frameworks for connection so as to constitute a continuous tent framework. The tent framework has the advantages of less part specifications and low manufacturing cost and the tent is convenient to assemble, fold, detach and transport, the continuous tents in various scales can be assembled and built simply and quickly without professional staff according to local conditions, and the continuous tent frame has great stability, good safety and very strong applicability, and is suitable for large-scale popularization and application.
