Yet above-mentioned disclosed head rest regulating mechanism structure is comparatively complicated, installs and regulates trouble, and stability is not good enough again, needs to improve.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple and quick child safety seat for automobiles head rest regulating mechanism in addition at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of child safety seat for automobiles head rest regulating mechanism, comprise that backrest and height can be located at the head rest at backrest top with regulating, it is characterized in that the convex a plate that is provided with in described backrest top, this connecting panel has the pilot hole of vertical setting, aforesaid connecting panel is arranged at intervals with at least two positioning grooves along the pilot hole both sides, described head rest has the inner chamber that plugs for aforementioned connecting panel, the both sides of described head rest are respectively equipped with first side opening and second side opening, aforesaid first side opening and second side opening all communicate with the head rest inner chamber, described head rest one side flexibly is provided with a regulating plate, one cooperates the adjust bar of locating to be convexly set in aforementioned regulating plate bottom with aforementioned positioning groove also has the trend of moving to the pilot hole direction all the time, this adjust bar is by first side opening and through aforementioned pilot hole and stretch out aforesaid second side opening, and the head of this adjust bar is provided with the banking stop that a restriction adjust bar breaks away from second side opening.
Further, the opposite side that described head rest is relative with regulating plate forms a groove, described second side opening then is opened in this bottom portion of groove and stretches out for adjust bar, one compression spring is sheathed on a described adjust bar leading section and an end and this bottom portion of groove and offsets, and the other end and described banking stop medial surface offset.
Further, described adjust bar comprises the elongated portion that cooperates spacing limiting section with positioning groove and run through pilot hole, and aforesaid limiting section diameter is greater than the diameter that stretches into portion.
As preferably, two fulcrums that described regulating plate is isosceles trapezoid wide at the top and narrow at the bottom and the close corner by the upper end symmetry substantially are located at described head rest one side and are had elasticity, and described adjust bar then is positioned on the diad of described regulating plate bottom.
Compared with prior art, advantage of the present utility model is: push behind the banking stop between the adjust bar and positioning groove matching relationship and remove, can realize the head rest height adjustment, unclamp banking stop after having regulated, promptly locate, convenient to operation, during the location, adjust bar tightly cooperates with positioning groove, be difficult for displacement, so stability is good, integral structure is simple, assembles easy to process.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, child safety seat for automobiles in the present embodiment comprises base 3, backrest 2 and head rest 1, base 3 is located at backrest 2 bottoms, head rest 1 is located at backrest 2 tops and can be realized height adjustment, the convex a plate 21 that is provided with in backrest 2 tops, connecting panel 21 has the pilot hole 8 of vertical setting, and connecting panel 21 is arranged at intervals with a plurality of positioning grooves 6 along pilot hole 8 both sides.
In conjunction with shown in Figure 5, head rest 1 has the inner chamber 12 that plugs for connecting panel, head rest 1 both sides offer first side opening 11 and second side opening 13 respectively, first side opening 11 and second side opening 13 all communicate with inner chamber 12, head rest 1 one sides also flexibly are provided with a regulating plate 4, regulating plate 4 is isosceles trapezoid wide at the top and narrow at the bottom substantially, two fulcrums 41 of the close corner by the upper end symmetry are located at head rest 1 one sides and are had elasticity, convex with an adjust bar 5 on the regulating plate 4 bottom diad, see shown in Figure 6, adjust bar 5 comprises the elongated portion 52 that cooperates spacing limiting section 51 with positioning groove 6 and run through pilot hole, and limiting section 51 diameters are greater than the diameter that stretches into portion 52.
Make adjust bar 5 have trend to pilot hole 8 directions motions all the time because of regulating plate 4 has elasticity, adjust bar 5 passes first side opening 11, and through pilot hole 8 and stretch out second side opening 13, adjust bar 5 heads are provided with banking stop 42, and are fixing with screw 44.
