A cushion trampoline includes a boost damping device including a bed-body connection sleeve, a booster connection sleeve, a guardrail connection sleeve and a support connection standing tube. The booster connection sleeve is communicated with the support connection standing tube through a flexible device, the support connection standing tube is connected with a leg. An anti-friction inner sleeve is provided between the booster connection sleeve and the support connection standing tube, thus preventing the friction between tubes from destroying a protective layer of the tubes. The flexible device comprises an elastomer and an elastomer obstacle, the elastomer is provided in the inner part of the booster connection sleeve; a convex portion is provided on the elastomer obstacle, a hole, matched with the convex portion of the elastomer obstacle, is provided on the support connection standing tube, a groove, matched with the convex portion of the elastomer obstacle, is provided on the booster connection sleeve. The elastomer in the boost damping device, as a boost, cushion and damping material, and in the course of jumping, plays a boost, cushion and damping role and increases bearing capacity, thus achieving a better jumping effect. |
