A modified trampoline holder structure comprises a plurality of transverse tubes, six connection sleeves, and three supporting tubes. The transverse tubes are connected together into a ring shape. Each connection sleeve firmly clamps the joint of two adjacent transverse tubes. Each connection sleeve is inserted into an end opening of one supporting tube. Locking bumps are formed at two sides of the inner edge of each tube clamping portion. Corresponding locking grooves are formed at two sides of the joint of two adjacent transverse tubes. When the tube clamping portion firmly clamps the joint of two adjacent transverse tubes, the locking bump and the locking groove will be locked together. Each insertion tube portion is composed of at least two arc-shaped sheets. Detents that can be locked together are formed on the two arc-shaped sheets.
Une structure de support de trampoline modifiée comprend plusieurs tubes transversaux, six manchons de raccordement, et trois tubes supports. Les tubes transversaux sont raccordés ensemble en forme d'anneau. Chaque manchon de raccordement serre fermement la jonction de deux tubes transversaux adjacents. Chaque manchon de raccordement est introduit dans une ouverture d'extrémité d'un tube support. Des renflements de blocage sont formés des deux côtés du bord intérieur de chaque section de serrage de tube. Les gorges de blocage correspondantes sont formées des deux côtés de la jonction de deux tubes transversaux adjacents. Lorsque la section de serrage de tube serre fermement la jonction de deux tubes transversaux adjacents, le renflement de blocage et la gorge de blocage sont verrouillés ensemble. Chaque section de tube d'introduction est composée d'au moins deux tôles cintrées. Les crans qui peuvent être verrouillés ensemble sont formés sur ces deux tôles cintrées.
