[0005] The technical solution adopted by the utility model to solve the above technical problems is: the car child safety seat comprises a base and a seat arranged on the base, and is characterized in that it also comprises:

[0006] A lock seat is arranged between the seat and the base, connected to the base, and has an installation channel inside, the entrance of the installation channel is surrounded by a socket, and an upper opening communicating with the installation channel is arranged on the upper side of the lock seat;

[0007] A locking member is movably disposed in the installation channel, wherein a first end of the locking member is movably disposed in the installation channel and a second end extends out of an upper opening of the lock seat, and the second end of the locking member has a first state in which the lock seat is locked and connected to the seat and a second state in which the lock seat is unlocked and connected to the seat;

[0008] The seat belt buckle is adapted to the socket and can directly or indirectly act on the locking member after being inserted into the socket. The seat belt buckle can be inserted into the socket and cause the second end of the locking member to release the locking connection between the lock seat and the seat, thereby allowing the lock seat to be disconnected from the seat.

[0009] In order to facilitate the flexible unlocking or locking of the seat and the lock seat, preferably, a first connecting rod is provided at the bottom of the seat, and the second end of the locking member is partially recessed inward to form a slot that matches the outer peripheral shape of the first connecting rod. When the first connecting rod is inserted into the slot, the lock seat and the seat can be locked and connected, and when the first connecting rod is disengaged from the slot, the lock seat and the seat can be unlocked. The arrangement of the slot enables the first connecting rod to slide in or out along the slot wall of the slot to complete the locking or unlocking action.

[0010] In order to facilitate the user to adjust the posture of the locking member, preferably, a follower is further provided in the installation channel, the seat belt buckle pushes the follower and indirectly acts on the locking member, the follower is movably provided in the installation channel and can reciprocate forward and backward along the channel wall of the installation channel, the upper surface of the follower is partially recessed downward to form a first groove, the first end of the locking member is at least partially located in the first groove, the first groove has a front groove wall and a rear groove wall arranged in the front-to-back direction, when the seat belt buckle is inserted into the socket, the seat belt buckle pushes the follower to move backward, the front groove wall drives the first end of the locking member to move, and then the card slot is separated from the first connecting rod.
