The invention discloses a telescopic structure of a connecting plug and a child safety seat. The telescopic structure of the connecting plug comprises a plug connecting frame which is arranged on a base of the child safety seat in a front-back sliding mode; the plug connecting frame is provided with a plurality of first adjusting concave parts, and the plurality of first adjusting concave parts are sequentially arranged along the sliding direction of the plug connecting frame; the lock pin is elastically supported so as to allow the lock pin to be kept in a first locking state in which the first end of the lock pin extends into the first adjusting concave part; the first end of the lock pin is provided with an inclined surface which faces backwards; when the lock pin is in the first locking state, the lock pin can limit backward extending movement of the plug connecting frame relative to the base, and the inclined face makes contact with the edge of the first adjusting concave part so as to allow the plug connecting frame to do forward retracting movement relative to the base.
本发明公开了一种连接插头的伸缩结构以及儿童安全座椅。该连接插头的伸缩结构包括:插头连接架,可前后滑动地设置于所述儿童安全座椅的底座;所述插头连接架设置有多个第一调节凹部,所述多个第一调节凹部沿所述插头连接架的滑动方向依次排列;锁销,被弹性地支撑以允许所述锁销保持在其第一端伸入到所述第一调节凹部中的第一锁止状态;所述锁销的第一端具有斜面,所述斜面朝向后方;当所述锁销处于所述第一锁止状态时,所述锁销能够限制所述插头连接架相对于所述底座的向后伸出移动,所述斜面与所述第一调节凹部的边缘接触以允许所述插头连接架相对于所述底座做向前缩回移动。
