Unverified承重标注需区分'静态承重'和'动态承重'——蹦床跳跃时的冲击力可达体重的3-5倍，标称承重100kg的产品实际适合体重20-30kg以下儿童单人使用，多人同跳会显著超出安全冗余92% similar Unverified承重标注需看单人瞬时冲击承重而非静态承重，孩子跳跃时冲击力可达体重3-5倍，标注承重应≥使用者体重×3并预留成人陪同余量（建议整体承重≥100kg）92% similar Unverified承重标注要看动态承重而非静态承重，标称静态承重50kg的塑料滑梯实际安全使用体重上限约25-30kg，孩子跳跃冲击会放大受力2-3倍91% similar Unverified承重标注需留足冗余，实际使用应选标称承重≥孩子体重2倍的产品（如20kg孩子选承重40kg以上），因跳跃时瞬间冲击力远大于静态体重90% similar Unverified承重上限的标注需按同时使用人数评估：标注承重100kg的跳床若供两个孩子同时跳，动态冲击力可达静态重量的3-4倍，实际应选静态承重≥150kg的型号才安全；单人使用则孩子体重不超过标注上限的60%88% similar
