Description

A kind of child's safety seat for vehicle chair back angle regulator

Technical field

The utility model relates to a kind of child's safety seat for vehicle, relates in particular to a kind of child's safety seat for vehicle chair back angle regulator.

Background technology

Child's safety seat for vehicle is to aim at child safety to ride in an automobile and a kind of base device of taking advantage of of design-calculated, it is by the angle of inclination of the adjusting chair back and the use location of chair inherently safe band, to children provide one comfortable, safety take advantage of the seat ring border, in the former child's safety seat for vehicle, for the angle that makes the chair back can be adjusted, mainly contain two kinds of structures, one is single rail structure: monolateral slide rail is installed in the centre of the chair back and base, the last slide rail and the chair back link, glidepath and base link, the centre has different positions, hole to cooperate, and reach the purpose of chair back angular adjustment, but the chair back is bigger with respect to rocking of base; Another kind of structure is the double sided slider bar structure, and slide rail is installed on the relatively-stationary base: the problem that this structure has avoided the chair back easily to rock with respect to base, but need two hands to operate the adjusting that could realize chair back angle simultaneously, very inconvenient during use.In sum, existing chair back angle regulator, its structure is still waiting to improve.

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 upper rail, lower guideway, described lower guideway is installed on the base, described lower guideway is provided with upper rail, described upper rail, lower guideway is provided with porose, its main points are, described upper rail is provided with the upper rail cross beam frame, the inside of described upper rail cross beam frame is provided with registration mast, described registration mast is provided with sliding pin, the top of upper rail cross beam frame is provided with handle, described handle both sides are respectively arranged with the hole, described two slotted holes are and are similar to " eight " font and arrange, removable pin stretches into handle and goes up in the hole that is provided with, the top of described handle is provided with first elastic parts, in the middle of the described upper rail cross beam frame in-to-in, the inboard of two registration masts also is provided with second elastic parts, described registration mast one end stretches into second elastic parts, the other end stretches into upper rail, in the hole that lower guideway is provided with, this device has realized that the chair back is reliable with respect to the base combination, be difficult for rocking, and the adjustment of the one-hand operation child's safety seat for vehicle chair back, easy to operate.

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.

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 the adjustment of the one-hand operation child's safety seat for vehicle chair back, easy to operate.

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, described child's safety seat for vehicle chair back angle regulator mainly is made of upper rail 5, lower guideway 4, upper rail cross beam frame 6, handle 2 etc.

Described chair back angle regulator is installed between the chair back 1 and the base 3, is used to adjust the angle of the chair back 1 and base 3, provides comfortable, a safe seat ring border of taking advantage of to children.

Described lower guideway 4 is provided with upper rail 5, and described guide rail is provided with a round, and is preferred, is provided with plastic mattress 7 between upper rail 5 and the lower guideway 4, can reduce noise, the power of reducing friction when sliding.

Described upper rail 5 is provided with upper rail cross beam frame 6, the inside of described upper rail cross beam frame 6 is provided with registration mast 12, described registration mast 12 is provided with sliding pin 8, the top of upper rail cross beam frame 6 is provided with handle 2, described handle 2 both sides are respectively arranged with hole 13, described two slotted holes 13 are and are similar to " eight " font and arrange, and removable pin stretches in the hole 13 that is provided with on the handle 2.

The top of described handle 2 is provided with first elastic parts 9, and is preferred, and first elastic parts 9 is extension spring, and the other end of described elastic parts 9 is fixedly on the chair back 1.

In the middle of described upper rail cross beam frame 6 in-to-ins, the inboard of two registration masts 12 also is provided with second elastic parts 4, described registration mast 12 1 ends stretch into second elastic parts 4, the other end stretches in the hole that guide rail is provided with, preferred, second elastic parts 4 is a stage clip.

Preferably, the side of described handle 2 is provided with handle orienting lug 11, will shake hands 2 to be limited on the chair back 1, makes handle 2 limit the straight-line motion that directions be done front and back along handle orienting lug 11.

Its principle of work is: when needs are regulated chair back angle, as long as the thumb of a hand is pinned chair back front end, all the other four fingers are held handle, do the action of clenching fist then, handle will travel forward, at this moment, removable pin 8 moves to the other end in the hole 13 that is provided with on the handle 2, and the distance between the registration mast 12 reduces, registration mast 12 and upper rail 5, separate in the hole that lower guideway 4 is provided with, to shake hands 2 to move to the desired position, decontrol handle 2, the first elastic partss and will shake hands 2, again registration mast 12 is pushed up outward toward pulling back, stretch into upper rail 5 on the registration mast 12, in the hole that lower guideway 4 is provided with, thus the adjustment of realization chair back angle.

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.
