The invention discloses a headrest adjusting mechanism and a child safety seat, and relates to the technical field of safety seats. The safety pin is slidably connected into the through groove in the sliding piece. The trigger rod is arranged on the headrest in a sliding manner and is provided with a wedge-shaped part; the guide piece is fixedly connected to the safety pin, and a right-angled triangular guide groove is formed in the guide piece; the sliding column is fixedly connected to the trigger rod and is in sliding fit with the guide groove. The elastic force of the first elastic piece enables the wedge-shaped part of the trigger rod to abut against the sliding piece; the elastic force of the second elastic piece enables the second friction surface of the sliding piece to abut against the first friction surface; the elastic force of the third elastic piece enables the safety pin to be inserted into the safety groove or abut against the notch edge of the safety groove. The height of the headrest can be steplessly adjusted, and the headrest and the seat body can be further locked when emergency situations such as vehicle collision occur, so that the defect that the locking force of stepless adjustment is insufficient is overcome.
本发明公开了一种头枕调节机构及儿童安全座椅,涉及安全座椅技术领域,包括:滑动件滑动设置在头枕上;安全销滑动连接在滑动件上的通槽内;触发杆滑动设置在头枕上,触发杆具有一楔形部;导向件固定连接在安全销上,导向件上开设有呈直角三角形的导向槽;滑柱固定连接在触发杆上,滑柱与导向槽滑动配合;第一弹性件的弹力使触发杆的楔形部与滑动件抵接;第二弹性件的弹力使滑动件的第二摩擦面与第一摩擦面抵接;第三弹性件的弹力使安全销插接到安全槽内或抵接到安全槽的槽口边缘。本发明能够对头枕的高度进行无级调节,并且能够在车辆发生碰撞等突发情况时,将头枕和椅身之间进一步锁死,以弥补无级调节的锁紧力不足的缺陷。
