Base structure adapted for a seat body of a child safety seat
A base structure ( 100 ) adapted for a seat body of a child safety seat is provided and includes a first base ( 1 ), a second base ( 2 ), a locking component ( 3 ) and a releasing mechanism ( 4 ). The second base ( 2 ) is pivotally connected to the first base ( 1 ) and located above the first base ( 1 ). A locking hole ( 21 ) is formed on a bottom portion of the second base ( 2 ). The locking component ( 3 ) is slidably disposed on the first base ( 1 ). An end of the locking component ( 3 ) is for engaging with an end of the locking hole ( 21 ). An end of the releasing mechanism ( 4 ) is located inside the second base ( 2 ) and slidably disposed on another end of the locking hole ( 21 ). The releasing mechanism ( 4 ) is operated to push the locking component ( 3 ) to disengage from the locking hole ( 21 ) for unlocking the second base ( 2 ), so as to allow the second base ( 2 ) to pivot relative to the first base ( 1 ).
1. A base structure adapted for a seat body of a child safety seat, wherein the base structure comprises:
