The chair is a child chair, an old man chair or a growth chair, the height of the growth chair is adjustable, and the chair can be used for children and old people in different growth stages.

The adjustable dinner plate assembly shown in fig. 1-4 comprises an armrest 1, a dinner plate 2 connected to the armrest in a sliding manner, and an elastic limiting part 3 embedded in and fixed at the bottom of the armrest; the elastic limiting part 3 is matched with a clamping hole 22 arranged on the dinner plate 2 in a clamping way, so that the position of the dinner plate 2 is fixed.

The specific structure of each part is as follows:

the pair of armrests 1 are configured to be fixed to the seat longitudinal support 4 in bilateral symmetry, and include a bar-shaped body 11 and a connecting portion 12 located at a rear end of the bar-shaped body 11. The armrest is in threaded connection, clamping connection or two connection and matching with the seat longitudinal support through the connecting part 12.

In this embodiment, the bar-shaped main body 11 of the armrest 1 directly serves as a slide rail and is slidably connected to the slide groove 21, and the cross-sectional shape of the bar-shaped main body 11 matches the cross-sectional shape of the slide groove 21. The front end of the sliding chute 21 is open or closed.

The dinner plate 2 is provided with sliding grooves 21 which are arranged in parallel at two sides of the bottom surface and are used for connecting the handrails 1 in a sliding way, and the rear ends of the sliding grooves 21 are provided with openings which are used as inlets for the handrails to insert. The bottom wall or the side wall of the sliding chute 21 is provided with a clamping hole 22.

In this embodiment, the number of the locking holes 22 is at least 2, and the locking holes are parallel to the central axis of the sliding chute and distributed on the bottom wall of the sliding chute 21, so as to facilitate the operation. More clamping holes can be additionally arranged for expanding the adjusting range.

The elastic limiting member 3 is disposed corresponding to the fastening hole 22, and includes a base 31 and an elastic fastening block 32 fixed on the base, the base 31 is embedded in the bottom surface of the armrest 1, and the elastic fastening block 32 is configured to be elastically fastened to the fastening hole 22. The elastic limiting part 3 is arranged reasonably and is positioned at a position which is not easy to be found and touched by children, so that the wrong operation of the children is avoided, and the safety performance of the dining chair is improved.

The position adjustment principle of the dinner plate is as follows: after the elastic clamping blocks 32 are pressed and retracted into the base 31, the handrail 1 is inserted into the sliding grooves 21 of the dinner plate 2, the dinner plate 2 is slid until the elastic clamping blocks 32 correspond to the clamping holes 22, the elastic clamping blocks 32 automatically pop out downwards under the self elastic restoring acting force and are clamped into the clamping holes 22, and therefore the connection between the handrail 1 and the dinner plate is achieved. According to the use requirement, after the elastic clamping block 32 is pressed, the dinner plate 2 is adjusted to another position, so that the elastic clamping block 32 is matched with another clamping hole 22, and the position adjustment of the dinner plate 2 is realized. The arrangement can meet the requirements of children in different growth stages or other people of different types, prolong the service life of the dining chair and enlarge the application range.

In this embodiment, the elastic latch 32 faces the bottom surface of the handrail 1 and extends and retracts perpendicularly to the bottom surface of the handrail, and the latch hole 22 is located on the bottom wall of the sliding slot 21.

In other embodiments (not shown in the drawings), the number of the clamping holes is at least 2, and the clamping holes are distributed on the side wall (inner side wall or outer side wall) of the sliding groove, and correspondingly, the elastic clamping blocks on the elastic limiting pieces are arranged towards the side surface (inner side surface or outer side surface) of the handrail and are perpendicular to the side surface of the handrail to do telescopic motion.

In order to improve the convenience of attaching and detaching the armrest while securing the connection strength between the armrest 1 and the seat longitudinal support 4, as shown in fig. 1 and 5, the connection portion 12 includes the following portions:
