The invention discloses a rotary adjustment safety seat. The safety seat comprises: a seat body; a headrest; a height adjusting structure; a base, wherein a rotary hole is formed in the base; and a seat adjusting mechanism. The seat adjusting mechanism comprises: a rotating disc, wherein the rotating disc is rotatably arranged in the rotating hole, the seat body is arranged on the rotating disc, and a rotating part between the seat body and the base only comprises the rotating disc; a pull plate arranged between the seat body and the rotating disc and provided with a connecting end and a pulling end, wherein the connecting end is connected with the seat body, a clamping bolt is arranged at the pulling end, the pulling end can move up and down between the seat body and the rotating disc, when the pulling end moves downwards, the clamping bolt can be driven to be inserted into the limiting part on the rotating disc, and when the pulling end moves upwards, the clamping bolt can be drivento be pulled out. The rotating disc is arranged between the seat body and the base, the area of the rotating disc is large, the bearing capacity is strong, the rotating disc is not easy to damage, noteasy to incline and block, and the rotation is stable. And the cross section area of the rotating disc is large, and the machining precision requirement is low, so that the machining cost can be reduced.
本发明公开了一种旋转调节安全座椅,包括:座椅本体、头枕、调高结构,底座,底座上设有转孔;座椅调节机构,座椅调节机构包括:转盘,转盘可转动地设在转孔内,座椅本体设在转盘上,且座椅本体与底座之间的转动部件仅包括转盘;拉板,拉板设在座椅本体和转盘之间,拉板具有连接端和拉动端,连接端与座椅本体相连,拉动端上设有卡栓,拉动端可在座椅本体和转盘之间上下活动,当拉动端向下活动时可带动卡栓插入转盘上的限位部,当拉动端向上活动时可带动卡栓拔出。根据本发明通过在座椅本体和底座之间设置转盘,转盘面积大、承重能力强,转盘不易损坏也不易歪斜、卡死,转动平稳。转盘的截面面积较大,加工精度要求较低,从而可降低加工成本。
