Description

A kind of child chair

Technical field

This utility model relates to a kind of chair, especially one medicated cushion and the adjustable chair of backrest structure.

Background technology

Existing chair is common in medicated cushion and is fixed on support, or medicated cushion lifts under the driving of the assemblies such as cylinder. In addition, if medicated cushion can move forward and backward in the horizontal direction, can more efficient adjustment user sitting posture.

Chinese patent literature disclose one section of name be called a kind of can before and after the utility model patent of seat cushions that regulates, publication number is CN201384260, it connector including medicated cushion body, being arranged on seat support rack, bottom fore-and-aft direction at medicated cushion body is parallel offers two strip grooves, connector has two flanges being inlaid in this strip groove, gathering sill is offered in described strip groove, flange top offers screwed hole, flange is fixed on gathering sill by screw rod, and can along gathering sill slide anteroposterior; The sidewall of described flange offers location tooth bar, the driving device of press-button structure it is provided with in medicated cushion body, this driving device has and stretches in strip groove and keep unclamping with location tooth bar or the clutch dop of clamping, when clutch dop and location tooth bar clamping, connector is fixed in the strip groove of medicated cushion body; When clutch dop unclamps with location tooth bar, connector can move forward and backward in the strip groove of medicated cushion body, and front and back position is adjusted.

Utility model content

This utility model solves the technical problem that the child chair being to provide a kind of design unlike the prior art, it is achieved that the front and back position of medicated cushion and backrest is adjustable, and the purpose that overall steadiness is good.

In order to solve above-mentioned technical problem, this utility model adopts following scheme:

A kind of child chair, including backrest and medicated cushion, backrest and medicated cushion are arranged on spinal column, described spinal column includes spinal column and lower spinal column, and lower spinal column turns forward, and upper spinal column tilts backwards, backrest is arranged on spinal column, and adjustable along upper spinal column position, medicated cushion is arranged on lower spinal column, and adjustable along lower spinal column position.

Compared to the prior art, the beneficial effects of the utility model are by upper and lower for spinal column two parts, upper spinal column rear-inclined, lower spinal column top rake, when medicated cushion is when lower spinal column up-down adjustment position, medicated cushion will be made to adjust forward or backward simultaneously, in like manner, backrest during up-down adjustment position, also can move forward and backward on the upper spinal column of rear-inclined, and this structure is particularly suitable for child, when child's body development is grown tall, needing to adjust upward medicated cushion and backrest, health takes up room increase simultaneously, and medicated cushion is moved rearwards by forward expanding the accommodation space of chair with backrest.

On the basis of such scheme, this utility model also does following improvement:

Described lower spinal column is arranged one group of spacing hole, base is fixed on the sleeved support of band, this sleeve set is on lower spinal column, and by drawing pin knob to coordinate with spacing hole, sleeve slides up and down along lower spinal column, and coordinated with spacing hole by the pin knob that draws installed on it, when behind sleeve slip relevant position, pull and draw pin knob to be automatically inserted into spacing hole, sleeve is fixed on lower spinal column, when needs continue to adjust sleeve portion, will pull and draw pin knob to extract spacing hole, sliding sleeve regulates, and simple in construction is easily controllable.

Arranging one group of spacing hole on described upper spinal column, backrest is hinged on the sleeved support of band, and this sleeve set is on upper spinal column, and by drawing pin knob to coordinate with spacing hole, similar with base operating principle, this simple in construction is easily controllable.

Arranging the balancing spring keeping backrest to maintain conventional sense between described backrest and the hinged end of back bracket, balancing spring can keep backrest not by maintaining rotine positioning under External Force Acting, keeps appearance and modeling, optimizes the result of use of backrest.

Described spinal column is arranged on base, and base bottom installs one group of roller, base is installed roller and is easy to mobile.

Described upper spinal column is one-body molded with lower spinal column, and upper spinal column and lower spinal column are integrally machined molding, compared with fixing with welding or fixation kit, has higher steadiness.

Described spinal column is provided with graduation mark, it is possible to improves and reconciles degree of accuracy, record condition data etc.

Fig. 1 is the structural representation of this utility model embodiment.

Fig. 2 is backrest and backrest support frame articulated structure schematic diagram in embodiment.

Accompanying drawing labelling:

1 time spinal column; Spinal column on 2; 3 sleeves; 4 spacing holes; 5 draw pin knob; 6 medicated cushions; 7 backrests; 8 bases; 9 articulated sections; 10 articulated slabs; 11 bearing pins; 12 balancing springs.

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is elaborated.

This utility model by spinal column shape-designing to chair, solves medicated cushion and effect that backrest locus regulates, and simple in construction is easy to operate. The content that this part embodiment relates to includes how to regulate medicated cushion, how to regulate backrest, how Automatic adjusument backrest stress etc.

Such as Fig. 1, this utility model includes the spinal column being arranged on chair base 8, and under spinal column, half turns forward (in Fig. 1 be front to the direction of medicated cushion 6), namely descends spinal column 1, and spinal column the upper half, toward rear-inclined, namely goes up spinal column 2. Installing the support of medicated cushion 6 on lower spinal column 1, this support is to be sleeved on lower spinal column 1 by a sleeve 3. Sleeve 3 installs one and draws pin knob 5, the one group of spacing hole 4 drawing pin knob 5 and be arranged on lower spinal column 1 sidewall coordinates, realize sealed on lower spinal column 1 of sleeve 3 and separate, specific operation process is: when sleeve 3 is adjusted to target location, pull and draw pin knob 5 to insert spacing hole 4, sleeve 3 is fixed on lower spinal column 1, when sleeve 3 needs to continue to regulate the position on lower spinal column 1, pull and draw pin knob 5 to extract spacing hole 4, sleeve 3 and lower spinal column 1 separate, and continue the regulating sleeve 3 position on lower spinal column 1.

In like manner, backrest 7 passes through sleeve, draws pin knob and upper spinal column 2 to coordinate, and concrete structure, with reference to medicated cushion, repeats no more again.
