The invention relates to a folding joint and a child carrier. The folding joint comprises a first seat body and a second seat body, wherein the first seat body is provided with a first accommodating cavity and a first clamping part; the second seat body is pivotally connected with the first seat body through a pivot, and the second seat body is provided with a second accommodating cavity and a second clamping part; the locking piece has an unlocking state, a first locking state and a second locking state; the elastic piece is used for applying axial force to the locking piece; when the locking piece is in the unlocking state, the locking piece shrinks towards the interior of the first containing cavity so as to be clamped with the first clamping part and separated from the second clamping part. When the locking piece is in the first locking state or the second locking state, the locking piece is driven by the elastic piece to partially stretch into the second containing cavity so as to be clamped with the first clamping part and the second clamping part at the same time. When the locking piece is in the first locking state, the axial clamping depth of the locking piece and the second clamping part is a first depth, when the locking piece is in the second locking state, the axial clamping depth of the locking piece and the second clamping part is a second depth, and the first depth is larger than the second depth.

    本发明涉及一种收折关节和儿童载具。本发明的收折关节包括:第一座体,具有第一容纳腔和第一卡合部;第二座体,通过枢轴与第一座体枢转连接,第二座体具有第二容纳腔和第二卡合部;锁止件,具有释锁状态、第一锁止状态和第二锁止状态;弹性件,用于向锁止件施加轴向力;当锁止件处于释锁状态时,锁止件向第一容纳腔中收缩以与第一卡合部卡合而与第二卡合部分离;当锁止件处于第一锁止状态或第二锁止状态时,锁止件被弹性件驱动而部分地伸入第二容纳腔中以与第一卡合部、第二卡合部同时卡合;锁止件在第一锁止状态时其与第二卡合部的轴向卡合深度为第一深度,锁止件在第二锁止状态时与第二卡合部的轴向卡合深度为第二深度,第一深度大于第二深度。
