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
The present invention relates to a kind of lock-bit system of child safety seat, especially relate to and be connected lock-bit system between a kind of chair back of child safety seat and base.
Background technology
Nowadays child safety seat is known, on open market, there are split type child safety seat and integral type child safety seat, split type child safety seat is because the end back of the body can separate, and product weight is lighter separately, is convenient to the advantages such as fitting operation and becomes more and more popular at present.At present, existing split type child safety seat comprises the chair back and base, the bottom of the chair back is provided with front anchor shaft and rear anchor shaft, on base, be provided with the position-limited trough that is positioned at base rear side, be positioned at locking mechanism and the red green indicating piece of lock-bit of base front side, locking mechanism is connected with the red green indicating piece of lock-bit, the red green indicating piece of lock-bit comprises red indication end and green indication end, while carrying out lock-bit operation, must first the rear anchor shaft of the chair back be snapped in position-limited trough, again front anchor shaft is locked in locking mechanism, complete after lock-bit operation, the embolium indication end of the red green indicating piece of lock-bit is positioned at indication window below, indication window shows that lock-bit completes, when current anchor shaft does not snap in locking mechanism, red indication end is positioned at indication window below, indication window shows that lock-bit does not complete.
There is following defect in this structure: after in this structure, anchor shaft snaps in position-limited trough, front anchor shaft snaps in locking mechanism, between position-limited trough and locking mechanism, there is not contact, while only having current anchor shaft to snap in locking mechanism, indicating window eloquence can show that lock-bit completes, when after anchor shaft do not snap in position-limited trough, when front anchor shaft snaps in locking mechanism, indication window also can show that lock-bit completes, when user operates, rear anchor shaft may occur not to be snapped in position-limited trough, front anchor shaft snaps in the situation of locking mechanism, now indication window shows that lock-bit completes, making user take for lock-bit completes, thereby generation potential safety hazard.
Summary of the invention
Technical matters to be solved by this invention is to provide and is connected lock-bit system between a kind of chair back of child safety seat of the user's of preventing maloperation and base, in this connection lock-bit system, in the time that rear anchor shaft is not locked, user cannot lock front anchor shaft, and only have in the time that rear anchor shaft and rear anchor shaft are simultaneously locked, indicating window eloquence can show that lock-bit completes, thereby has avoided there is anchor shaft not by locked situation because of carelessness.
The present invention solves the problems of the technologies described above adopted technical scheme: between a kind of child safety seat chair back and base, be connected lock-bit system, comprise preposition locking mechanism, rearmounted locking mechanism, actuating spindle and Mobile base, described Mobile base is subject to drive towards the application force of base rear end direction, in described Mobile base, be provided with position-limited trough, described actuating spindle is positioned at described position-limited trough, described position-limited trough comprises and is wholely set horizontal slot and tipper, described tipper is obliquely and extends as initiating terminal by the terminal of horizontal slot, described rearmounted locking mechanism is connected with described Mobile base by pull bar,
