Description

A kind of adjustable dining chair

Technical field

The utility model is related to technical field of furniture more particularly to a kind of adjustable dining chairs.

Background technology

Dining chair is indispensable furniture in modern house.For the dining chair of adult, size tends to meet The demand of different users, but children dinning chair has its particularity, to ensure that children's is safe to use, height, which has, accordingly to be wanted It asks.When using the excessive dining chair of height, children's lifts, and safety cannot ensure that children are active in addition, be easier to The case where falling down.In addition, child height increase it is very fast, can not adjust the dining chair of height generally after using one or two years with regard to because It is shorter and cannot be satisfied requirement.Pair and adjustable dining-chair for child, gone out to need outside higher reliability, surface cannot press from both sides Seam or hole, avoid children's finger from being caught in.

Invention content

The utility model provides a kind of adjustable dining chair, it is adjustable for height simultaneously, avoid structure from crack or hole occur Hole and the requirement that disclosure satisfy that reliability.

In order to reach the purpose, the utility model adopts the following technical solution：

Including chair body, Telescopic chair body includes seat, the chair back and chair leg, it is characterised in that：Further include being socketed in leg The telescopic outrigger in outside, leg upper edge leg extending direction are provided with track groove, on the track groove inner surface It is provided with the first connecting hole, the telescopic outrigger is equipped with the protrusion being connected in the track groove and is located at the flexible branch The groove of leg outer side, the protrusion are equipped with the second connecting hole, are connected in first connecting hole and second connecting hole Bolt, the bolt include bolt head, and the bolt head is flushed with the telescopic outrigger outer surface, are set on the outside of the bolt head There is knob.

Telescopic outrigger will be screwed into groove and positioning can be realized after track groove is moved to corresponding position as a result,.

As a preferred embodiment, elasticity layer is arranged in the telescopic outrigger lower end, the elasticity layer surface is provided with protrusion.

The frictional force between telescopic outrigger and ground is improved as a result,.

As a preferred embodiment, the elastic layer is rubber layer.

As a preferred embodiment, the telescopic outrigger inside lower end is provided with enclosed air bag, the air bag is stretched with described The fitting contact setting of contracting supporting leg inner surface.

Structural failure is avoided to damage children as a result,.

As a preferred embodiment, the groove is cylinder, the relief width between the bolt head and the groove-side surface Degree is less than 0.3mm.

The finger of children is avoided to be stuck in the gap as a result,.

As a preferred embodiment, the knob is the platy structure vertical with the bolt head outer surface.

As a preferred embodiment, the quantity of second connecting hole is one.

To sum up, compared with prior art, the utility model has the advantage of：Telescopic outrigger is moved to corresponding positions along track groove It postpones, will be screwed into groove and positioning can be realized, exposed connecting hole is not present in body structure surface at this time, and may be to children The gap damaged；The setting of closed air bag avoids structural failure from damaging children.

Specific implementation mode

As depicted in figs. 1 and 2, which includes chair body 1, and Telescopic chair body 1 includes seat 11, the chair back 12 and chair leg 13, is gone back Telescopic outrigger 2 including being socketed in 13 outside of chair leg, 13 upper edge chair leg of chair leg, 13 extending direction are provided with track groove 131, track Be provided with the first connecting hole 132 on 131 inner surface of slot, telescopic outrigger 2 be equipped be connected to the protrusion 21 in track groove 131 with And the groove 22 positioned at 2 outside of telescopic outrigger, protrusion 21 are equipped with the second connecting hole 23, the first connecting hole 132 is connect with second Bolt 3 is connected in hole 23, bolt 3 includes bolt head 31, and bolt head 31 is flushed with 2 outer surface of telescopic outrigger, bolt head 31 Outside is equipped with knob 32.For telescopic outrigger 2 after track groove 131 is moved to corresponding position, will be screwed into groove 22 can be real It now positions, in adjustment process, telescopic outrigger 2 is covered in 132 outside of track groove 131 and the first connecting hole always, ties at this time Exposed connecting hole is not present in structure surface.

Elasticity layer is arranged in 2 lower end of telescopic outrigger, and elastic layer surface is provided with protrusion 21, to improve telescopic outrigger 2 and ground Frictional force between face.Elastic layer is chosen as rubber layer.2 inside lower end of telescopic outrigger is provided with enclosed air bag 4, air bag 4 Setting is contacted with the fitting of 2 inner surface of telescopic outrigger.At this point, air bag 4 plays cushioning effect, structural failure is avoided to cause children Injury, enclosed air bag 4 can work for a long time.

Groove 22 is cylinder, and the gap width between 22 side surface of bolt head 31 and groove is less than 0.3mm, avoids children Finger be stuck in the gap.Knob 32 is the platy structure vertical with 31 outer surface of bolt head.Second connecting hole 23 Quantity is one, and the hole being more than is not present in dining chair body structure surface at this time, disclosure satisfy that relevant specification of country requirement.

Described above is only the explanation to the utility model so that those of ordinary skill in the art's can completely implements this Scheme, but be not limitations of the present invention, those skilled in the art can be as needed after reading this specification The modification of not creative contribution is made to the present embodiment, these are all without creative modification, but as long as in this practicality It is all protected by Patent Law in novel right.
