Description

A kind of catch gear of spare seat

Technical field

The present invention relates to a kind of self-propelled vehicle child passenger and use constrained system, the concrete catch gear that relates to a kind of spare seat.

Background technology

Being connected of automobile baby safe hand basket and spare seat need guarantee through a reliable and stable mechanism.This mechanism not only will satisfy quick loading and unloading automobile baby safe hand basket but also safety preferably must be arranged.Be that automobile baby safe hand basket and complementary seat need when being in coupled condition assurance mechanism to throw off.This mechanism needed smooth opening to be obstructed when automobile baby safe hand basket and complementary seat will separate.

Summary of the invention

The object of the present invention is to provide a kind of catch gear that can effectively lock the spare seat of automobile baby safe hand basket and spare seat.

For solving the problems of the technologies described above, realize above-mentioned technique effect, the present invention realizes through following technical scheme:

A kind of catch gear of spare seat; Comprise stay bearing plate, fixed hook, position limiting slide block assembly, lever, spring and handle; One side of said stay bearing plate is a folding part; The top of said stay bearing plate offers a recess, and said fixed hook comprises a buckle and a right angle draw-in groove, and said position limiting slide block assembly is made up of the slide bar and the slide block that can slide up and down that is arranged on the said slide bar; Said fixed hook is through the rotating indent that is arranged on said stay bearing plate of rotating shaft; Said buckle and the interlock each other of said recess; The terminal rotating of said handle is arranged on the said stay bearing plate, and the end that said lever is fixed on said handle can rotate with the rotation of said handle, and said spring one end is connected the lower end of said lever; The other end is connected on the said folding part; Said position limiting slide block assembly is fixed on the said stay bearing plate, the last end in contact of the lower end of said slide block and said lever, the following end in contact of the upper end of said slide block and said fixed hook.

The principle of work of the catch gear of spare seat of the present invention is following:

1, fixed car safety infant carrier:

, the adapter shaft of baby safe infant carrier presses down simultaneously in snapping in the recess of fixed hook; Lever is moving on the promotion slide block under the effect of extension spring, and sliding snapping in soon in the right angle draw-in groove of fixed hook moved on handle is automatic; The adapter shaft of locking infant carrier, the baby safe infant carrier fixes.

2, take off the automotive safety infant carrier:

Press handle, drive the lever rotation, lever spurs slide block downwards, and slide block is shifted out from the right angle draw-in groove of fixed hook, and fixed hook will rotate around the shaft, and fixed hook opens, and the baby safe infant carrier can be taken away.

Compared with prior art can not only reduce loaded down with trivial details fixing step and more safe and reliable through automobile children safety chair of the present invention.

Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification sheets, below with preferred embodiment of the present invention and conjunction with figs. specify as after.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
