The high adjusting device of this headrest, simple structure is convenient for make safe and reliable, convenient operation. The outward appearance is leveled, elegant appearance.

Description

A kind of child's safety seat for vehicle headrest height adjustment device

Technical field

This utility model relates to a kind of child's safety seat for vehicle headrest height adjustment device.

Background technology

At present, for protection children head by bus, adapt to child's difference height, simultaneously on child's safety seat for vehicle mostly Use adjustable headrest.Child's safety seat for vehicle headrest height adjustment device on market, some operations inconvenience, some outward appearances The most beautiful.

Utility model content

Different because taking child height, to preferably protect his head it is necessary to adjust the height of chair headrest easily.

This utility model solves its technical problem and be the technical scheme is that

One, a matrix is done at the rear portion at headrest (1), inserts child safety seat chair back ledge (6).Pacify child On full backrest ledge, do some regulation location dimples.

Two, in headrest regulation drain pan (2) both sides, a circular hole (2-1), propping up as lever bolt (3) are made respectively Support point.

Three, the top (3-2) of lever bolt, flushes with an occiput posterior appearance.The lower lobes of lever bolt Part, as latch (3-3), is inserted in pit corresponding on child safety seat chair back ledge.In the middle part of lever bolt two The cylinder of side, as rotating shaft (3-1), inserts in the circular hole (2-1) of headrest regulation drain pan both sides, and rotatably.

Four, the rotating shaft (3-1) in the middle part of lever bolt puts torsion spring (4), and one end of torsion spring is pressed in lever bolt bullet Spring draw-in groove position (3-4), the other end withstands on lid (5)

Five, the outward appearance of lid (5) flushes with an occiput posterior appearance, and the upper inner (5-1) of lid is pressed in lever The stepped locations on latch top (3-5), makes the top (3-2) of lever bolt flush with an occiput posterior appearance.At lid The leg (5-2) of 2 semicircles is done on upper inner both sides, is arranged on both sides in the middle part of lever bolt (3-1) position, protects lever Latch support post.

After using this technical scheme, child safety seat headrest adjusts and becomes very convenient.According to child height, behaviour on the other hand Making just headrest to be transferred to the position that is suitable for, simple to operate, safe and reliable, flat appearance, elegant in appearance, structure is simple simultaneously Single, it is simple to produce.

Detailed description of the invention

It is described further below in conjunction with the accompanying drawings:

This utility model is a kind of child's safety seat for vehicle headrest height adjustment device.As it is shown in figure 1, comprise headrest 1, Headrest regulation drain pan 2, lever bolt 3, torsion spring 4, lid 5, child safety seat chair back 6, totally six part compositions.

As Figure 1-Figure 5, in the present embodiment, do a matrix at the rear portion of headrest (1), insert child safety seat Backrest ledge (6).On child safety seat chair back ledge, do some regulation location dimples.

In the present embodiment, in headrest regulation drain pan (2) both sides, make a circular hole (2-1) respectively, insert as lever The strong point of pin (3).

In the present embodiment, the top (3-2) of lever bolt, flush with an occiput posterior appearance.Lever bolt Lower protrusion as latch (3-3), insert in pit corresponding on child safety seat chair back ledge.Lever In the middle part of latch, the cylinder of both sides is as rotating shaft (3-1), inserts in the circular hole (2-1) of headrest regulation drain pan both sides, and rotatably.

In the present embodiment, the rotating shaft (3-1) in the middle part of lever bolt puts torsion spring (4), and one end of torsion spring is pressed in thick stick Rod-type latch spring draw-in groove position (3-4), the other end withstands on lid (5).

In the present embodiment, the outward appearance of lid (5) flushes with an occiput posterior appearance, the upper inner (5-1) of lid Being pressed in the stepped locations of lever bolt top (3-5), the top (3-2) making lever bolt is neat with an occiput posterior appearance Flat.Inside top of closure, the leg (5-2) of 2 semicircles is done on both sides, is arranged on both sides in the middle part of lever bolt (3-1) position, Protection lever bolt support column.

In the present embodiment, when pressing lever bolt top with hands, lever bolt just turns around rotating shaft (3-1) Dynamic, thus latch (3-3) is extracted from backrest pit, make headrest thread off with backrest, at this moment, in that context it may be convenient to be raised and lowered Headrest high and low position.It is adjusted to after suitable position unclamps hands, lever bolt (3) resilience under the effect of torsion spring (4), make thick stick Rod-type latch (3) just rotates backward around rotating shaft (3-1), and latch (3-3) is automatically inserted in the pit that backrest is corresponding, by head Pillow is secured firmly on child safety seat, protects the head of child to greatest extent.
