Connection capturing system between chair backrest and base of child safety chair

Abstract

The invention discloses a connection capturing system between the chair backrest and the base of a child safety chair. The connection capturing system comprises a front capturing mechanism, a rear capturing mechanism, a control shaft and a movable seat. The movable seat is drive by an acting force facing the rear end of the base. A limit groove is formed in the movable seat. The control shaft is located in the limit groove. The limit groove comprises a horizontal groove and an oblique groove which are integrated. The oblique grooves uses the terminal of the horizontal groove as the starting end and obliquely extends upwards. The rear capturing mechanism is connected with the movable seat through a pull rod. A linkage switch is disposed on the front capturing mechanism. The front capturing mechanism controls on and off of the linkage switch. When the linkage switch is off, the position of the control shaft is locked, and when the linkage switch is on, the control shaft can move upwards. The connection capturing system has the advantages that misoperation caused by carelessness of a user can be avoided.

Description

technical field [0001] The invention relates to a locking system of a child safety seat, in particular to a connection locking system between a seat back and a base of the child safety seat. Background technique [0002] Nowadays, child safety seats are well known. Generally, there are split-type child safety seats and integral child safety seats on the market. The split-type child safety seat can be separated because the bottom back can be separated, and the individual products are lighter in weight and easy to install and operate. Currently becoming more and more popular. At present, the existing split-type child safety seat includes a seat back and a base. The bottom of the seat back is provided with a front fixed shaft and a rear fixed shaft. The lock mechanism is connected with the lock red and green indicator. The lock mechanism is connected with the lock red and green indicator. The lock red and green indicator includes a red indicator end and a green indicator end. ...

AI Technical Summary

Problems solved by technology

[0003] This structure has the following defects: in this structure, the rear fixed shaft snaps into the limiting slot, and the front fixed shaft snaps into the locking mechanism. There is no connection between the limiting slot and the locking mechanism, and only the current fixed shaft snaps into the locking position When the mechanism is in place, the indicator window will display that the lock position is completed. When the rear fixed shaft is not snapped into the limit slot and the front fixed shaft is snapped into the lock mechanism, the indication window will also display that the lock position is completed. When the user operates, it may be When the rear fixed shaft does not snap into the limit slot and the front fixed shaft snaps into the locking mechanism, the indicator window shows that the locking is completed, which makes the user mistakenly think that the locking is completed, thus causing potential safety hazards
