A folding frame and an outdoor table or outdoor chair using the folding frame. The folding frame comprises a base, a plurality of support legs hinged around the base, a plurality of extension support bars hinged on the support legs and capable of folding, and a locking mechanism. The base is provided with a plurality of gear racks. Both sides of each gear rack are configured with vertically distributed first teeth part. Both sides of the upper end of the support leg are configured with circularly distributed second teeth part. The upper end of the support leg is positioned between two gear racks, and the second teeth part of the support leg mesh with the first teeth part of the gear rack. When the locking mechanism can lock the unfolded support legs, the gear rack also locks the support legs.

A foldable desk includes a tabletop, two outer legs, and two inner legs. An outer leg connecting rod and an inner leg connecting rod are connected to upper ends of the two outer legs and the two inner legs, respectively. Each of the two outer legs is rotatably connected to a one of the two inner legs in an X-structure. The tabletop is located between the two outer legs, and a front end of a bottom surface of the tabletop is disposed with a buckle configured to be buckled to the inner leg connecting rod when the foldable desk is unfolded for use. The two outer legs or the two inner legs are telescopic, and the tabletop is configured to be placed horizontally or switched to be placed in a state in which a front of the tabletop is lower than a rear of the tabletop.

A collapsible stand includes a carrying member, a first support frame unit and a second support frame unit respectively pivotally connected to the carrying member, a linking unit pivotally connected between the first and second support frame units for allowing the collapsible stand to be alternatively set between an extended position and a collapsed position, and a locking unit for locking the first and second support frame units to the carrying member selectively in the extended or collapsed position. The overall structure of the collapsible stand is simple and easy to operate. When set in the extended position, the first and second support frame units give a large area support to the carrying member, assuring high stability.

A folding table includes a table frame, having two crossbars and a plurality of stands, the two crossbars each have a folding portion, the plurality of stands are respectively pivoted to two ends of the two crossbars; a table plate, detachably mounted on the two crossbars; and at least one gravity lock, disposed at the folding portion, the gravity lock has a body provided with two longitudinal long grooves, two side sheets are respectively located at two sides of the body, one end of the two side sheets is combined with the crossbar, and the other end is pivoted to the body, the two side sheets each have a hook portion to shade a partial opening of a slot.
