Telescopic tent capable of expanding infinitely

The invention discloses a telescopic tent capable of expanding infinitely and relates to the technical field of tents. The tent comprises a plurality of inverted U-shaped supports which are linearly arranged, and a connecting fixing piece is arranged between two adjacent supports. According to the invention, the two adjacent door-type supports are connected through a cross rod, the cross rod is composed of two straight rods, the two straight rods are connected through hinged fixing bolts at a middle part, and the two ends of the straight rods are connected with the supports through connectingfixing bolts, so that the cross rod and the two door-type supports form a deformable parallelogram, and the purposes of convenient construction and disassembly, convenient telescopic control and infinite expansion are realized; by connecting two adjacent door-shaped supports on the connecting rods, the purposes of convenient construction and disassembly and convenient telescopic control are realized; and the adjacent thre
