Double-roof foldable tent
Disclosed is a double-roof foldable tent. The double-roof foldable tent includes a tent roof connection block, where a plurality of double-roof assemblies are arranged at a bottom of the tent roof connection block, the double-roof assemblies include connection rods, the connection rods are arranged at the bottom of the tent roof connection block, one sides of the connection rods are fixedly connected to fastener posts, the one sides of the connection rods are provided with double-roof rods, and one sides of the double-roof rods are provided with double-roof linkage rods. When the tent is unfolded, a ventilation gap is formed so that more wind passes through the gap, and a ventilation effect is better. Since wind passes through the gap, wind resistance is smaller, the use stability is improved, and air inside the tent can flow sufficiently. The tent can be folded as a whole and is convenient to store.
