The utility model another technical matters to be solved provides a kind of chair back and combines with base reliably, the child safety chair chair back angle regulator that is difficult for rocking.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of child safety chair chair back angle regulator; Comprise base, regulating mechanism and pass through this regulating mechanism chair back of base angular adjustment relatively; The upper surface that it is characterized in that said base has built-in chamber; These both sides, built-in chamber form a plurality of shift slots and chute respectively, and described regulating mechanism comprises

Slide plate is connected fixing and is arranged in the built-in chamber and can moves forward and backward with the bottom surface of the aforementioned chair back, both sides have the boss with aforementioned chute bearing fit, are horizontally arranged with two bar-shaped troughs;

Shake hands, be arranged at aforementioned slide plate middle part and base ability front and back pulling relatively, the rear end has two through holes that are " eight " font;

Gear block is two, and each gear block is inserted in the bar-shaped trough separately and has first protuberance that crosses out bar-shaped trough and then can cooperate the location with shift slot and reaches second protuberance that upwards stretches out through hole; And

Bringing-back mechanism forces aforesaid two gear blocks to keep mutual open trend all the time.

The preferred following design of Bringing-back mechanism: described slide plate middle part has a junction, and described Bringing-back mechanism comprises a retracing spring and be located at the strut rail in the handle, and the front end of this retracing spring is connected with aforementioned strut rail, and the rear end then is connected with connecting portion.

Further, the bottom surface of the said chair back is protruding dome shape, and accordingly, the upper surface of said base is the dome shape with the suitable indent in aforementioned chair back bottom surface, and described slide plate is circular-arc.

It is L shaped grooved slide rail that said boss upper surface has the cross section, and accordingly, said base has the draw runner that cooperates with the slide rail guiding, and this draw runner is positioned at the chute top and inwardly stretches out.

Said chute and boss are curved from front to back setting.

For making moving of slide plate steadily reliable; Accurate positioning; Described built-in chamber diapire is convex to be provided with two arched ribs, and described a plurality of shift slot takes shape on the aforesaid arched ribs, accordingly; The lower surface of said slide plate forms and supplies the adaptive deep-slotted chip breaker of aforementioned arched ribs, and the port of said bar-shaped trough takes shape in a side of this deep-slotted chip breaker.

Said slide plate is processed for the non-metal flexible material, when having reduced chair angle greatly and having regulated fricative noise with reduced cost.

Compared with prior art, the advantage of the utility model is: the chair back combines with base reliably, be difficult for rocking, and the angle of inclination of the one-hand operation adjusting child safety seat chair back, easy and simple to handle; Integral structure is simple, is convenient to produce, assemble.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Like Fig. 1～shown in Figure 5; Child safety chair chair back angle regulator in the present embodiment comprises base 2, regulating mechanism and passes through this regulating mechanism chair back 1 of base 2 angular adjustment relatively; The upper surface of base 2 has built-in chamber 25, and these 25 both sides, built-in chamber form a plurality of shift slots 23 and chute 21 respectively.

Regulating mechanism comprises slide plate 3, handle 4, and gear block 5 and Bringing-back mechanism, slide plate 3 are connected with the bottom surface of the chair back 1 and are fixedly set in the built-in chamber 25 also and can move forward and backward.Both sides have the boss 31 that cooperates slip with chute 21, and vertical chute 21 directions have two bar-shaped troughs.Slide plate 3 in the present embodiment is processed for the non-metal flexible material, and fricative noise in the time of can reducing chair back angular adjustment has greatly also reduced simultaneously productive costs.Handle 4 is arranged at slide plate 3 middle parts and base 2 ability front and back pullings relatively, and the rear end has two through holes 41 that are " eight " font.

In conjunction with shown in Figure 6, gear block 5 is two, and each gear block 5 is inserted in the bar-shaped trough separately and has and crosses out bar-shaped trough and then can cooperate first protuberance 51 of location to reach second protuberance 52 that upwards stretches out through hole with shift slot 23.

Bringing-back mechanism forces two gear blocks 5 to keep mutual open trend all the time.Particularly, slide plate 3 middle parts have a junction 33, Bringing-back mechanism comprise a retracing spring 6 and be located at the handle in strut rail 42, the front end of this retracing spring 6 is connected with strut rail 42, the rear end then is connected with connecting portion 33.

The bottom surface of the chair back 1 is protruding dome shape, and accordingly, the upper surface of base 2 is the dome shape with the suitable indent in the chair back 1 bottom surface.The all curved from front to back setting of chute 21 and boss 31.Built-in chamber 25 diapires are convex to be provided with two arched ribs 22, and a plurality of shift slots 23 take shape on the arched ribs 22, and accordingly, the lower surface of slide plate 3 forms the deep-slotted chip breaker 32 that supplies arched ribs 22 adaptive, and the port of bar-shaped trough takes shape in a side of this deep-slotted chip breaker 32.It is L shaped grooved slide rail 311 that boss 31 upper surfaces have the cross section, and accordingly, chute 21 upper surfaces have the draw runner 24 that cooperates with slide rail 311 guiding, and draw runner 24 is positioned at chute 21 tops and inwardly stretches out.As shown in Figure 3, base 2 designs for hollow out near the part 25 of chute 21.

In conjunction with Fig. 7 and shown in Figure 8; When needing to regulate the angle of inclination of the chair back 1 and base 2; Pulling handle 4 travels forward, and second protuberance 52 that handle 4 drives the gear pin laterally bounces back two gear pins 5 to intermediary movements; And then make first protuberance 51 throw off shift slot 23, slide thereby make the chair back 1 relative base 2 do front and back; After having regulated angle; Unclamp handle 4, under the effect of retracing spring 6, second protuberance 52 of gear block will move along through hole 41; And then two gear blocks 5 are separated from each other, first protuberance 51 of gear block just stretches out and corresponding shift slot 23 adaptive location again.
