Compared with the prior art, this scheme of adoption, the user only need use a hand can accomplish the high regulation of resting the head on, and is simple and convenient, in addition simple structure.
Description
Technical field
The utility model belongs to Automobile Products field, relates in particular to a kind of child safety seat.
Background technology
Along with expanding economy; improving constantly of people's living standard, automobile, especially domestic sedan car has more and more become the daily walking-replacing tool of people; in general; adult uses of seat belts and substantially can ensure its safety, and the safety of children's ride-on small passenger car is not resolved, for this reason; develop the child seat aiming at designed for children; child seat is fixed on automotive seat, because child seat more agrees with the body type of children, better protection can be formed to children.
Because child height change is very fast, along with child height change, the height of headrest also will change thereupon, therefore, market there is the product that can regulate height of headrest in a large number, but the height of headrest regulating mechanism of prior art all needs to make with the hands to regulate height: a hand shift by-pass cock, another hand adjustment head restraint height is very inconvenient during use.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, provides a kind of headrest lifting mechanism that only can realize the child safety seat that height of headrest regulates with a hand.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of headrest lifting mechanism of child safety seat, comprise the chair back and be installed on the headrest on the described chair back, it is characterized in that: between the described chair back and described headrest, be provided with handle, described handle have two chutes arranged in inverted "eight" shape, described chute is equipped with block, the side of described block has the shoes be inserted in described chute, described chair back both sides offer the some slots distributed up and down, one end activity of described block is inserted in described slot, the other end activity of described block is inserted on described headrest, described handle upper end offers the first hole, described headrest offers the second hole, and the upper side in described second hole is higher than the upper side in described first hole.Adopt this programme, user only needs use hand can complete adjustment to height of headrest, simple and convenient, and structure is simple.
In order to obtain better technique effect, further technical measures also comprise: the above-mentioned chair back has the bar hole that the above-below direction along the described chair back distributes, described headrest and the described chair back are by being connected through the bolt of described bar hole.The cooperation of bar hole and bolt serves the effect of guiding, and user is unlikely to when regulating height to cause headrest to occur deflection due to power thrusts problem.
Further technical measures, the back side of above-mentioned headrest has recessed area, and described handle is arranged in this recessed area.Such scheme makes the cooperation of the chair back and headrest, and the cooperation of handle and headrest is all compacter.
Further, between above-mentioned handle and described headrest, there is block response agency.The effect of response agency is that only need decontrol handle after pillow height degree adjustment right overhead puts in place can make
As preferably, above-mentioned response agency comprises spring, and one end apical grafting of described spring is on described handle, and other end apical grafting is on described headrest.
Compared with prior art, user of the present utility model only needs use hand can complete adjustment to height of headrest, simple and convenient, and structure is simple.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Embodiment 1, a kind of headrest lifting mechanism of child safety seat, comprise the chair back 1 and be installed on the headrest 2 on the described chair back 1, it is characterized in that: between the described chair back 1 and described headrest 2, be provided with handle 3, the back side of described headrest 2 has recessed area, described handle 3 is arranged in this recessed area, described handle 3 have two the chute 3a arranged in inverted "eight" shape, described chute 3a is equipped with block 4, the side of described block 4 has the shoes 41 be inserted in described chute 3a, the described chair back 1 both sides offer the some slot 1a distributed up and down, one end activity of described block 4 is inserted in described slot 1a, the other end activity of described block 3 is inserted on described headrest 2, between described handle 3 and described headrest 2, there is response agency, described response agency comprises spring 5, described handle 3 has a projection, described headrest 2 has a spring mounting seat, one end apical grafting of described spring 5 is on the projection of described handle 3, and other end apical grafting is on the spring mounting seat of described headrest 2, and described handle 3 upper end offers the first hole 3b, described headrest 2 offers the second hole 2a, the upper side of described second hole 2a is higher than the upper side of described first hole 3b.
The described chair back 1 has the bar hole 1b that the above-below direction along the described chair back 1 distributes, described headrest 2 and the described chair back 1 are by being connected through the bolt of described bar hole 1b.
When regulating height of headrest, first user holds the first hole 3b of handle, upwards lift, due to the effect of two chute 3a that inverted "eight" shape is arranged, the pin of block 4 moves to centre, thus block 4 is extracted in 1a from slot, at this moment, the upper side of the first hole 3b of handle 3 and the second hole 2a of headrest 2 is in same plane, therefore, now, user can lift handle 3 and headrest 2 simultaneously, when lift puts down handle to during proper height, under the effect of response agency, block inserts in slot automatically, the height of resting the head on is fixed, namely the whole control process of headrest is completed.Whole process only needs the participation of a hand, simple to operation, brings great convenience to user.
Although the utility model has illustrated by reference to preferred embodiment and has described, those skilled in the art should understand, and in the scope of claims, can do the various change in form and details.
