Patent Description:
Outdoor sliding-door tents are outdoor tent products. In general, a rack constitutes the main body of an outdoor sliding-door tent, the top of the rack has a canopy structure that can be opened and closed, sliding door assemblies are provided around the rack, each sliding door assembly comprises a door frame structure fixed on the rack and sliding doors that can be opened and closed on the door frame structure, and each sliding door comprises a border structure and a door body embedded in the border structure. A conventional border structure generally comprises two horizontal sliding door border tubes and two vertical sliding door border tubes; and a conventional door frame structure comprises two horizontal door frame tubes and two vertical supporting and fixing frame tubes. The prior art has the following problems: <NUM>. The assembly of the four borders is troublesome. In particular, when screws are used for fixation, it is difficult to align the positions of the holes. As the border structure is a rectangular structure, when the assembly of a corner has an error, it will be impossible to correctly assemble all borders; <NUM>. It is noisy to open or close a sliding door assembly; <NUM>. The structure of the vertical sliding door borders is vertically asymmetric, resulting in a complex manufacturing process; <NUM>. The installation structure between the horizontal door frame tubes and the vertical supporting and fixing frame tubes is complex and the installation is laborious; <NUM>. When the vertical supporting and fixing frame tubes are mounted to a ring beam of the rack, screws need to be tapped from the inner side of the vertical borders of the door frame and are exposed, affecting the appearance; <NUM>. On the inner side of a conventional vertical supporting and fixing frame tube, there are two double-rib structures used for fitting a border of the door panel, but only one double-rib structure is actually used. The redundant double-rib structure affects the appearance; <NUM>. The chute tubes are groove tube structures that are integrated with the vertical sliding door border tubes of the sliding door. The chute tubes are used to contact the door frame or another sliding door when the present sliding door is closed, and have a sealing effect. As only some vertical sliding door border tubes need to be provided with chute tubes, normally both vertical sliding door border tubes with chute tubes and vertical sliding door border tubes without chute tubes need to be manufactured, adding difficulties to the manufacturing. Further, the vertical sliding door border tubes with chute tubes and the vertical sliding door border tubes without chute tubes are not interchangeable, causing inconvenience to assembly. <CIT> shows a sliding door assembly suitable for an outdoor tent comprising a door frame structure and sliding doors. Each sliding door comprises a door panel and a border structure comprising horizontal tubes and vertical tubes, mounted by first fasteners. Plastic parts are built in the upper and lower ends of the vertical tubes. Said parts have guide holes providing guidance for the connection of the first fasteners between the horizontal tubes and the vertical tubes. <CIT> Al shows a sliding door assembly comprising a door frame structure and sliding doors. Each sliding door comprises a door panel and a sliding door frame comprising horizontal tubes and vertical tubes mounted by first fasteners. Parts are built in the upper and lower ends of the vertical tubes. Said parts have guide holes providing guidance for the connection of the first fasteners between the horizontal and the vertical tubes. <CIT> shows a door frame structure and sliding doors. Each sliding door comprises a door panel and a door frame with vertical tubes and horizontal tubes, inserted parts and mounting screws. <CIT> shows a door frame structure and sliding doors.
