Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
The head rest lifting regulating mechanism of a kind of child safety seat as shown in Figure 1 to Figure 3, including seat 1 and head rest 2,
Also include the backrest plate 3 being fixedly installed on the chair back 11 of seat 1, can be arranged at up or down the chair back 11 and backrest plate 3 it
Between head rest plate 4, head rest 2 is installed on the top of head rest plate 4.Being vertically arranged with pull bar 5 on head rest plate 4, pull bar 5 is provided with spacing
Hole 51, head rest plate 4 is provided with the limited post 41 corresponding with spacing hole 51, realizes pull bar by spacing hole 51 and limited post 41
5 coordinate with the sliding of head rest plate 4.Being provided with pull-rod spring 52 between pull bar 5 and head rest plate 4, pull-rod spring 52 is used for making pull bar 5
There is the movement tendency moved down relative to head rest plate 4.The bottom of pull bar 5 is hinged with lower clamping block 54 by lower transmission arm 53, when
When pull bar 5 is vertically movable relative to head rest plate 4, lower clamping block 54 is horizontal relative to head rest plate 4 under the drive of lower transmission arm 53
Move back and forth；The side of backrest plate 3 is provided with some and lower clamping block 54 lock fit backrest plate lock hole 31 from top to bottom.
Specifically, in order to improve the locking effect to pull bar 5, to improve the pull bar 5 position when lock-out state further
Degree of putting, the bottom of pull bar 5 is hinged with two lower transmission arms 53, and two lower transmission arms 53 are arranged in "eight" shape, links under two
The free end of arm 53 is all hinged with lower clamping block 54, and two sides of backrest plate 3 are symmetrically arranged with some backrest plate lock holes 31.
Operation principle of the present utility model is: during original state, and under the effect of pull-rod spring 52, pull bar 5 passes through the second line of a couplet
The downward clamping block 54 of swing arm 53 applies lateral thrust so that lower clamping block 54 is entrapped in backrest plate lock hole 31, and pull bar 5 is in
Lock-out state, now head rest plate 4 cannot move up and down relative to backrest plate 3；When needing the height regulating head rest 2, the most upwards
Pulling pull bar 5, pull-rod spring 52 to be compressed, pull bar 5, during upper shifting, applies horizontal stroke by lower transmission arm 53 to lower clamping block 54
To pulling force, forcing lower clamping block 54 to depart from backrest plate lock hole 31, pull bar 5 is in released state, now by the liter of head rest plate 4
Fall is mobile, just can conveniently realize the regulation to head rest 2 height；After head rest 2 altitude mixture control completes, releasing lever 5, at pull bar
Under the effect of spring 52, pull bar 5 moves down relative to head rest plate 4, and drives lower clamping block 54 transverse shifting by lower transmission arm 53,
Force lower clamping block 54 again to snap in corresponding backrest plate lock hole 31, again realize the locking to pull bar 5.
The both sides of head rest plate 4 are respectively arranged with side and lean on 6, and side is coordinated with head rest plate 4 horizontal sliding by sliding panel 7 by 6；The back of the body
Having two the oblique chutes 32 arranged in inverted "eight" shape on backup plate 3, it is right with corresponding tiltedly chute 32 that each sliding panel 7 is equipped with
The angled-lift splits 71 that should arrange.By arranging said structure, when user regulates the height of head rest 2, on the one hand, head rest plate 4 can lead to
Crossing sliding panel 7 drives side to lean on 6 vertical motions, and on the other hand, sliding panel 7 is also in the mating reaction of angled-lift splits 71 with oblique chute 32
Under, driving side is by 6 relative to head rest plate 4 traverse motion, thus it is suitable to ensure that head rest 2 and side can be in all the time by 6
Relative position so that user takes the most comfortable.
Being additionally provided with shoulder belt plate 8 between head rest plate 4 and backrest plate 3, shoulder belt plate 8 has the shoulder belt hole 81 passed for shoulder belt；Shoulder
Band plate 8 sliding vertical with head rest plate 4 coordinates, specifically, in order to make shoulder belt plate 8 position degree when moving relative to backrest plate 3
Higher, head rest plate 4 is provided with guide runner 42, and shoulder belt plate 8 is provided with the guide chute 82 coordinated with guide runner 42 sliding.Shoulder belt
The upper end of plate 8 is provided with the limited block 83 being correspondingly arranged with head rest plate 4, is provided with shoulder belt flat spring between shoulder belt plate 8 and head rest plate 4
84, shoulder belt flat spring 84 has relative to the movement tendency moved on head rest plate 4 for making shoulder belt plate 8；The top of pull bar 5 is by upper
Transmission arm 55 is hinged with clamping block 56, and when pull bar 5 is vertically movable relative to head rest plate 4, upper clamping block 56 is at upper transmission arm
Relative to head rest plate 4 traverse motion under the drive of 55；The side of shoulder belt plate 8 is provided with joins with the locking of upper clamping block 56 respectively
Lock hole 86 under lock hole 85 and shoulder belt plate on the shoulder belt plate closed.
Specifically, in order to improve the position degree of shoulder belt plate 8 further, the upper articulation of pull bar 5 has two upper transmission arms
55, two upper transmission arms 55 are arranged in "eight" shape, and the free end of two upper transmission arms 55 is all hinged with clamping block 56, shoulder belt
Two sides of plate 8 are all correspondingly provided with on shoulder belt plate lock hole 86 under lock hole 85 and shoulder belt plate.
When pulling up pull bar 5, upper clamping block 56 also can be by the lateral pull effect from pull bar 5 so that lock
Determining block 56 to disappear the locking of shoulder belt plate 8, shoulder belt plate 8 will be relative to head rest plate 4 under the elastic force effect of shoulder belt flat spring 84
Upper shifting, until its limited block 83 is inconsistent with head rest plate 4, now under shoulder belt plate, lock hole 86 is relative with the position of upper clamping block 56
Should, if now releasing lever 5, clamping block 56 just can be made to be inserted under shoulder belt plate in lock hole 86；If user thinks shoulder belt
When the position of plate 8 is too high relative to head rest plate 4, user only need to press down on shoulder belt plate 8, force shoulder while pulling pull bar 5
Band plate 8 moves down relative to head rest plate 4, makes lock hole 85 on shoulder belt plate corresponding with the position of upper clamping block 56, then unclamps and draw
Bar 5, makes clamping block 56 be inserted on shoulder belt plate in lock hole 85.To sum up, by arranging said structure, can be effective during use
Adjust the relative position between shoulder belt plate 8 and head rest plate 4, use more convenient.
The above is only better embodiment of the present utility model, therefore all according to described in this utility model patent claim
Structure, feature and principle done equivalence change or modify, be all included in this utility model patent claim.
