Summary of the invention

The utility model is at deficiency of the prior art, provide a kind of chair back with respect to base in conjunction with reliable, be difficult for rocking and the child's safety seat for vehicle chair back angle regulator of one-hand operation.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:

A kind of child's safety seat for vehicle chair back angle regulator, comprise base, the chair back, its main points are, be provided with slide plate on the described base versatilely, the top of described slide plate is provided with the chair back, two wing bases of described slide plate are provided with limiting stopper, the inboard end of described slide plate is provided with elastic parts, the two ends of elastic parts are respectively arranged with left slider, right slide block, described left slider, be respectively arranged with locating dowel pin on the right slide block, the movable handle that is provided with on the locating dowel pin, described handle is provided with two slotted holes, described slotted hole is " eight " font and arranges, the other end of described slide plate is provided with elastic parts, and the other end of elastic parts is arranged on the base, and this structure chair back is reliable with respect to the base combination, be difficult for rocking, and one-hand operation is easy to operate to the adjustment of the child's safety seat for vehicle chair back.

In the technique scheme, the both sides of described handle are provided with the handle orienting lug, and handle is limited on the chair back, make handle limit the straight-line motion that direction is done front and back along the handle orienting lug.。

In the technique scheme, also be provided with the anti-slip limiting stopper on the base, when preventing from excessively to stretch, slide plate pulls the potential safety hazard of existence.

Beneficial effect: the utility model compared with prior art has following beneficial effect:

1) the utility model chair back with respect to base in conjunction with reliable, be difficult for rocking, and one-hand operation is easy to operate to the adjustment of the child's safety seat for vehicle chair back.

2) adopted the inclined-plane matching mechanism in the mechanism, realized resetting of sliding pin with extension spring and stage clip simultaneously, made mechanism safer, reliable.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

See Fig. 1～Fig. 3, child's safety seat for vehicle chair back angle regulator is mainly by base 1, and slide plate 2 shakes hands 6, slide block, formations such as elastic parts.

Be provided with slide plate 2 versatilely on the described base 1, two wing bases 1 of described slide plate 2 are provided with limiting stopper 3, described slide plate 2 one front end inside are provided with elastic parts 10, the top of described slide plate 2 is provided with the chair back 4, the two ends of elastic parts 10 are respectively arranged with left slider 8, right slide block 5, and described left slider 8, right slide block 5 are provided with locating dowel pin 13, and are preferred, described left slider 8, right slide block 5 can be arranged to one with locating dowel pin 13, convenient processing.

Described handle 6 is provided with two slotted holes, and described slotted hole is " eight " font to be arranged, and slotted hole is placed on the locating dowel pin 13 of left slider 8,5 settings of right slide block, and the other end of described slide plate 2 also is provided with elastic parts 9, and the other end of elastic parts 9 is arranged on the base 1.

Preferably, also be provided with anti-slip limiting stopper 7 on institute's art base, when preventing from excessively to stretch, slide plate 2 pulls the potential safety hazard of existence.

Preferably, the both sides of described handle 6 are provided with handle orienting lug 11, and handle orienting lug 11 will shake hands 6 to be limited on the chair back 4, make handle 6 limit the straight-line motion that directions be done front and back along handle orienting lug 11.

Its principle of work is: when the needs adjusting angle, the thumb of a hand is pinned the chair back 4 front ends, all the other four fingers are held handle 6, do the action of clenching fist then, handle 6 will travel forward, left slider 8, to move toward the top of slotted hole " eight " word on the locating dowel pin 13 that right slide block 5 is provided with, that is to say, and force locating dowel pin 13 to move toward middle, thereby drive left slider 8, right slide block 5 moves toward middle, make left slider 8, right slide block 5 breaks away from limiting stoppers 3, makes slide plate 2 move to actual needs, is arranged on that the chair back 4 also and then moves on the slide plate 2, thereby realize the adjustment of the chair back 4 angles, after angular adjustment is finished, unclamp handle 6, handle 6 is under the pulling force of elastic parts, and under the elastic force double action of elastic parts, back move left slider 8, right slide block 5 is pushed to the outside, thereby is limited at once more in the limiting stopper 3.

Though the utility model is described by preferred embodiment, yet the utility model is not limited to embodiment as described herein, also comprises various changes and the variation done under the situation that does not break away from the utility model scope.
