[0023] Combine the following Figure 1-Figure 4 The utility model is described in detail.

[0024] Example

[0025] An adjustable chair for a nursery or a nursery training room comprises a vertically arranged backboard 10 and a tray frame 14 connected to the backboard 10 and arranged horizontally, a seat board 13 is hinged on the backboard 10, fixing holes 11 are provided on the backboard 10 and the tray frame 14, a threaded hole 24 opposite to the fixing hole 11 is provided on the seat board 13, a fixing screw 25 movably passing through the fixing hole 11 and threadedly connected to the threaded hole 24 is provided on the backboard 10 or the tray frame 14, an opening 12 for infant movement is provided on the tray frame 14, and a supporting mechanism is connected to the supporting mechanism, and a plurality of universal wheels 4 are connected to the supporting mechanism.

[0026] When the seat 13 is fixed to the tray frame 14 by the fixing screw 25, it can be used for infants and young children to sit on; when the seat 13 is fixed to the back plate 10 by the fixing screw 25, the opening 12 on the tray frame 14 is exposed, and the baby is carried into the opening 12, and the baby is assisted to walk by the movement of the universal wheel 4, thereby realizing the function of a walker.

[0027] The supporting mechanism includes at least two sleeves 7 and a movable tube 8 movably arranged in the sleeve 7, a plurality of insertion holes 19 are vertically arranged on the sleeve 7, a plug rod 20 cooperating with the insertion hole 19 is movably penetrated through the side wall of the movable tube 8, a compression spring 21 connected with the plug rod 20 is arranged in the movable tube 8, an annular baffle plate 22 is arranged on the plug rod 20, a rotating plate 23 cooperating with the annular baffle plate 22 is rotatably arranged in the movable tube 8, and a pressing rod 15 abutting against the upper end of the rotating plate 23 and used to deflect the rotating plate 23 is movably arranged on the side wall of the tray rack 14.

[0028] In order to meet the needs of infants and young children of different heights and ages, the support mechanism is set as a height-adjustable mechanism. Specifically, the movable tube 8 can move up and down in the sleeve 7, and the insertion rod 20 is inserted into the socket 19 to achieve the locking of the movable tube 8. When the position of the movable tube 8 needs to be adjusted, it is only necessary to press the pressing rod 15 inward, and the pressing rod 15 pushes the rotating plate 23 to deflect. The rotating plate 23 will abut the annular baffle 22 and retract the insertion rod 20 into the movable tube 8, so that the insertion rod 20 is disengaged from the socket 19 and unlocked. At this time, the tray rack 14 is moved as a whole to adjust the height of the tray rack 14. After adjusting to the right position, the pressing rod 15 is released, and the compression spring 21 pops the insertion rod 20 outward and inserts it into the socket 19.

[0029] The universal wheel 4 is connected to a mounting plate 5 movably mounted on a sleeve 7 , a first U-shaped groove 18 is provided on the mounting plate 5 , a horizontal thread on the mounting plate 5 penetrates a limiting screw 16 , and two limiting holes 6 cooperating with the limiting screw 16 are provided on the sleeve 7 .

[0030] The mounting plate 5 moves on the sleeve 7, thereby controlling all the universal wheels 4 to rise and fall simultaneously; when the universal wheels 4 protrude from the lower end of the sleeve 7, the walking function can be performed; when the universal wheels 4 do not protrude from the lower end of the sleeve 7, the seat function is adjusted to prevent the seat from moving easily. The mounting plate 5 is fixed by the limit screw 16 and the two limit holes 6; the setting of the mounting plate 5 increases the support surface composed of several universal wheels 4, thereby increasing the stability of the walker; the setting of the first U-shaped groove 18 is to prevent the mounting plate 5 from blocking the infant from sitting on the seat by himself.

[0031] The bottom of the sleeve 7 is connected to the bottom plate 1, and the bottom plate 1 is provided with a second U-shaped groove 2 opposite to the first U-shaped groove 18 and a circular groove 3 for the universal wheel 4 to pass through. After the universal wheel 4 is stored, the bottom plate 1 is in contact with the ground, which prevents the universal wheel 4 from moving freely when the seat function is used, and at the same time increases the support area of ​​the seat, increases the stability of the ride, and prevents the seat from tipping over. Since the circular groove 3 is provided to protect the circumference of the universal wheel 4, it is prevented that the universal wheel 4 presses on the feet of other infants and young children during use. The second U-shaped groove 2 has the same function as the first U-shaped groove 18.

[0032] The bottom of the tray frame 14 is connected with a sitting bag 17. The sitting bag 17 supports the buttocks of some younger babies to prevent the babies from falling during walking.

[0033] Armrests 9 are provided on both sides of the seat 13, and the distance between the two armrests 9 is greater than the width of the back plate 10. The armrests 9 are provided to facilitate the protection of infants and young children and prevent them from falling from the side; after the seat 13 is fixed to the back plate 10, the armrests 9 can be stored and placed on both sides of the back plate 10. A detachable safety belt (not shown in the figure) can also be provided between the two armrests 9 to fix some younger infants and prevent them from falling forward.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
