The invention also provides a child car seat which is provided with the connecting component.
The working principle of the child car seat is as follows:
when the child car seat is not installed on the car seat, the third locking member 5 is not connected with the anchoring mechanism, the sixth matching portion 61b is far away from the fifth matching portion 51, the first locking member 31 enables the first limiting portion 311 to be inserted into the first locking groove 11 under the action of the elastic force of the first elastic member 32, the second locking member 41 enables the second limiting portion 411 to be inserted into the second locking groove 12 under the action of the elastic force of the second elastic member 42, namely, the first locking mechanism and the second locking mechanism are both in a locking state, the first inclined surface on the sliding assembly 61 is far away from the arc-shaped outer contour surface on the second locking member 41, and the second inclined surface on the first locking member 31 is far away from the outer cylindrical surface of the lock pin, as shown in fig. 2, at the moment, the relative position between the fixing member 1 and the telescopic member 2 is fixed, and relative sliding between the fixing member 1 and the telescopic member 2.
When the third locking member 5 is connected and locked with the anchoring mechanism, the third locking member 5 rotates relative to the telescopic member 2, under the action of the tension spring 64, the sliding assembly 61 is pulled to slide backwards, so that the sixth matching portion 61b is gradually clamped into the fifth matching portion 51, when the sliding assembly 61 slides backwards, the first locking member 31 is driven to synchronously slide backwards, so that the rear end surface, i.e. the inclined surface, of the first limiting portion 311 abuts against the first open groove 21, when the sliding assembly 61 continuously slides backwards, the first locking member 31 rotates around the rotating connection part between the first locking member 31 and the sliding assembly 61 through the interaction between the inclined surface and the first open groove 21 until the first limiting portion 311 is separated from the first locking groove 11, the first locking mechanism is unlocked, in the process, the third locking member 5 is connected and locked with the anchoring mechanism, and the second locking mechanism is still in the locked state, as shown in fig. 3. In this state, the fixed member 1 can be slid backward relative to the extensible member 2, the fixed member 1 and the extensible member 2 are brought together, and the seat is brought closer to the backrest of the car seat as shown in fig. 4.
When the child car seat needs to be detached from the car seat, a person holds the operating element 62 and the rotating shaft 7 at the same time, applies force to the operating element 62, so that the operating element 62 slides forward in a direction close to the rotating shaft 7 relative to the rotating shaft 7, the operating element 62 slides forward to drive the sliding assembly 61 to slide forward synchronously, after the third locking element 5 is pulled by the tension spring 64 to rotate reversely by a certain angle relative to the telescopic element 2, the connection between the third locking element 5 and the anchoring mechanism is released, and the sixth matching part 61b is far away from the fifth matching part 51, as shown in fig. 5.
