Abstract: A swiftly-assembling collapsible goal and a portable frame are provided. The goal includes a plurality of poles engaged together to form a frame of the goal. Engaged poles are associated with each other with a hinge disposed at a corner region therebetween. One of two engaged poles is provided with a tenon protruding from a first end thereof and the other pole of the two engaged poles is provided with a mortise slot at a second end of the other pole facing toward the first end. The tenon defines a wedge-shaped slot along an axis of the pole. An insert pin is engaged to the tenon with a wedge-shaped rib engaged in the wedge-shaped slot. The insert pin has two tabs laterally extending from two side surfaces thereof. The pole with mortise slot defines two slits in two sidewalls which define the mortise slot, for respectively receiving the two ribs therein. The tenon and the insert pin are received in the mortise slot.
