An outdoor barbecue tent capable of quick assembling and folding disclosed in the present invention includes a tent body and a shelf. The tent body includes a sunshade part and at least two fixed columns arranged on the sunshade part. A movable column relatively movably mounted to each of the at least two fixed columns, and two diagonal positions of the shelf are mounted with a supporting rod respectively, the supporting rods are connected to the fixed columns, and the shelf is connected to the fixed columns. The structure thereof utilizes the foldability of the folding tent body, the retractability of the movable column, and the convenient mounting of the shelf to achieve the ease assembling of the shelf, and greatly reduces the time of assembling the outdoor barbecue tent capable of quick assembling and folding. At the same time, the shelf can be detached on the column, thus achieving the technical effect that the folded barbecue tent body is small in size and convenient to carry.

The invention comprises a scalable and foldable multipurpose frame structure configured with a generally flat-roof as a worksite and a peaked-roof as a recreational canopy, a cover retaining system and a ventilation system. The frame structure comprises a plurality of foldable wall trusses connecting a plurality of upright telescopic posts transversely forming a wall frame structure and a closed loop geometric footprint, a plurality of foldable roof trusses connecting a centrally disposed roof assembly to either the telescopic posts or the wall trusses transversely forming the roof. The cover retaining system comprises various spring clips for known-size frame members, and various clamps for unknown-size frame members, to secure roof and wall cover to the frame structure. The ventilation system comprises an enclosure that can utilize standard furnace air filters and existing air circulation devices. Multiple frame structures can be linked together to scale up space.

Environment isolation structures may include a frame and flexible panels at least partially covering, and attached to, the frame. The frame may include multidirectional node connectors including multiple locations for attachment. At least some of the locations for attachment may be located on different sides of the multidirectional node connectors. Poles configured to telescope to selectively fixable lengths may include connectors affixed to longitudinal ends of the poles. Each connector may be configured to selectively attach to a respective location for attachment on a given side of a respective multidirectional node connector to form the frame.

A portable shade shelter has a plurality of canopies including at least a first canopy and a second canopy. The first canopy is disposed over the second canopy, and the first canopy is capable of being spaced apart from the second canopy in a vertical direction such that air is capable of flowing between the first canopy and the second canopy. Each of the first canopy and the second canopy includes a plurality of openings configured to permit air and light to pass through the respective first canopy and second canopy.

The present invention comprises a novel foldable yurt structure generally consisting of at least two foldable lattice walls and a foldable lattice roof. The foldable roof is to be positioned substantially on top of the foldable walls. Once the roof sits on the wall and securely and fastened with zip ties, an inner tension band or rope is encircled to prevent structure expand and hold the structure in substantially same structural position. The whole structure is covered by PVC tarpaulin, Vinyl tarpaulin, or polyethylene tarpaulin.

An improved pole frame structure of a foldable tent includes upright poles, side cross support rod assemblies, and a top support rod unit. The top support rod unit includes a top module provided with a limiting component, top support rod assemblies, and oblique support rods. One end of each oblique support rod is connected to the respective top support rod assembly by means of a slider provided with a stopper, and the other end of the oblique support rod is pivotally connected to the respective side cross support rod assembly. The structure enhances, by means of the stopper and the limiting component, the stability of the oblique support rods supporting tent cloth, and prevents the tent cloth from being damaged by the oblique support rods.
