The invention discloses a center lock structure, comprises a chassis, rotary sliding sleeve and a center rod, the top of the rotary sliding sleeve is circumferentially and slidely connected with the chassis; and the center rod is extended into the rotary sliding sleeve along the top of the chassis, an elastic member is provided at one side on the bottom of the center rod, the elastic member is exposed outside the center rod when there is no external force, and the elastic member is concealed in the center rod when squeezed by an external force; in the invention, by the center rod, upper and lower rotary sliding sleeve, through holes and the accommodating grooves for pressing or releasing the elastic member, the structure can be unlocked by rotation and pull-down.

Disclosed is a tent frame, a unit tent and an extendable cubic tent group. The tent group is assembled from a plurality of unit tents sharing edge structures. The unit tent consists of an inflatable tarpaulin and a tent frame. The tent frame includes bases, columns and beams. The beam is provided with at least a first water channel and a second water channel in a length direction. The present invention is simplified in the structures of the columns and the beams, which is more beneficial to coping with the situation of large water volume. Besides, the assembly of small parts can be reduced, and the stability of the structure can be enhanced, so that the structural weight of the overall frame is greatly reduced while the hidden water discharge function is reserved.

Disclosed is a double-spliced foldable tent with central lifting and automatic opening and closing structure, including two groups of central tops, one group of middle frame and two groups of edge frames. Any group of edge frame and middle frame are connected by telescopic fork frame. Two groups of side inclined frames are arranged between a group of central top and middle frame. At least one group of side inclined frame is arranged between a group of central top and a group of edge frame. One group of central tops includes an upper top and a lower support locked or separated by spring pin. One group of side inclined frame includes a first inclined rod hinged on upper top at one end and a second inclined rod hinged on lower support at one end, of which the other end is hinged on the side wall of first inclined rod.

An awning mounting rack includes four stand columns; a first folding bracket is disposed between two adjacent stand columns; each stand column has a top holder. The top holder includes a first pole, a second pole and a support pole. The four stand columns include two first stand columns and two second stand columns; the other ends of the second poles connected to the first stand columns are pivot joined to the first top set, the non-end portions of the second poles connected to the first stand columns are respectively pivot joined to a first support rod, the ends of the first support rods are pivot joined to a first bottom set; the other end of the second poles connected to the second stand column are pivot joined to a second top set, the non-end portions of the second poles are pivot joined to a second support rod.

A sidewall attachment system for attaching decorative objects such as decorative flowers to a structure such as a tent to create a decorative display such as a flower wall. The sidewall attachment system generally includes a sidewall which is adapted to be removably secured to a structure such as a tent. The sidewall includes mounts and apertures for removably securing the upper end and sides, respectively, of the sidewall to the structure. The sidewall also includes a plurality of retainer strips adapted to removably engage with corresponding connector strips located on each of a plurality of panels adapted to be removably connected to the sidewall. Each of the panels includes a plurality of openings which function as grommets to retain any number of decorative attachments such as flowers to the panels to form a decorative display on the structure.

An expandable shelter includes a canopy adjustable in length along a longitudinal axis. Legs support the canopy in an A-frame configuration defining an apex angle along an upper ridgeline. A shaded or sheltered area that is variable in length and width is defined. A mobile shelter includes multiple protective structures, each supported by a respective generally vertical supporting column having a lower handle configured to be gripped and supported by a respective bearer. Each handle may be toroidal in shape for use at any angle. Non-level terrain may be traversed by coordinated movements of bearers with regard to each respective handle such that the protective structures are maintained in a desired configuration.
