Description
Technical field
The present invention relates to a kind of for automobile children safety chair and the fixing device of children, more particularly to one kind is for vapour
The lock catch connecting device of car child safety seat.
Background technology
The lock on automobile child seat that the current country is used all uses and installs one on double-hasp, each lock substantially
Safety belt, double-hasp, which is buckled together, to be fixed to protect children's safety by bus.In existing connected mode, the locking plate button of single lock
Firmly lock, this results in user and is possible to think that double-hasp is locked after single locking plate is pinned.So existing lock
There is single locking plate vacation lock in buckle device and user is mistakenly considered the potential safety hazard that two locking plates are all pinned.
The content of the invention
The technical problem to be solved in the present invention is：The present invention provides a kind of only two locking plates all locked whole locks
Just confirm the lock catch connecting device for automobile child seat of locking, it is ensured that the security of automobile child seat locking.
The technical solution adopted for the present invention to solve the technical problems is：A kind of lock for automobile child seat is connected
Device, it includes fixed component and movable part, and the fixed component includes installing in housing, button and clamp, the housing
There is slide plate group, the slide plate group includes slide plate one and slide plate two, has space, the slide plate between the slide plate one and slide plate two
It is connected with one on the spring one being fixed in housing, the slide plate two and is connected with the spring two being fixed in housing, it is described to press
Spring three is connected with button, the spring three is located between button and slide plate group, described clamp one end and button connects, the card
The one end of plate away from button has ratchet clamping part, and the clamp also has connecting portion, and the connecting portion is connected with ratchet clamping part, the card
Teeth portion width is more than connecting portion；The movable part includes bolt plate one and bolt plate two, the bolt plate one and bolt plate two
Opening and the hole one led to opening are formed with after docking in the end of bolt plate one and bolt plate two, the connecting portion can
Through space and opening, the ratchet clamping part can pass through hole one, and the ratchet clamping part cannot pass through space and opening；The fixation
When part is locked with movable part, the ratchet clamping part is located in hole one, and the spring three is in compression or relaxation state.
In order to prevent lock catch connecting device in locking, clamp and button are ejected outside housing next time in the promotion of spring three,
It is further preferred that offering hole two on the housing, the button is located in hole two, and the button surrounding has limited block,
