[0016] like Figure 1-5 As shown, a tilt adjustment mechanism of a baby dining chair includes a seat 1 and a base 2. The bottom of the seat 1 is fixedly connected to a connecting seat 3. The base 2 and the connecting seat 3 are connected by a support column 4. The upper end of the support column 4 is connected to the connecting seat 3, and the lower end of the support column 4 is fixedly connected to the base 2. A tilt adjustment mechanism is provided between the upper end of the support column 4 and the connecting seat 3; the tilt adjustment mechanism includes a supporting portion 31 at the bottom of the connecting seat 3, the front side of the supporting portion 31 is a supporting plane of a planar structure, and a plurality of supporting portions are provided on the front side of the supporting portion 31. The screw hole 32 is provided at the position corresponding to the screw hole on the upper part of the support column 4, and a through hole is provided that penetrates the support column 4 in the front and rear directions. An angle adjustment plate 5 is also provided between the upper end of the support column 4 and the abutment portion 31. The angle adjustment plate 5 includes a movable adjustment plate 51 and a fixed plate 52. The rear side of the fixed plate 52 is fixedly connected to the abutment plane, and the front side of the fixed plate 52 is an inclined surface. The rear side of the movable adjustment plate 51 and the front side of the fixed plate 52 are fitted together. The fitting surfaces of the fixed plate 52 and the movable adjustment plate 51 are mutually matched inclined surface structures. The joint surface of the section plate 51 is provided with mutually cooperating height adjustment teeth 53, and a long strip-shaped adjustment avoidance hole 54 is provided at the position corresponding to the through hole and the screw hole 32 of the fixed plate 52 and the movable adjustment plate 51. The thickness of the fixed plate 52 gradually decreases from top to bottom, and the upper end of the fixed plate 52 is provided with a support portion 55 protruding forward. The thickness of the movable adjustment plate 51 gradually increases from top to bottom; a plurality of screws 7 pass through the through hole and the adjustment avoidance hole 54 at the upper end of the support column 4 and are screwed on the corresponding screw hole 32 to fix the support column 4 to the abutment portion 31. An avoidance groove 33 is provided at the position of the upper end of the support column corresponding to the connecting seat 3, and one side of the avoidance groove 33 is flush with the abutting plane. The upper end of the support column 4 is accommodated in the avoidance groove 33, and the rear side of the upper end of the support column 4 abuts on the support portion 55 of the fixed plate 52, and the rear side surface of the upper part of the support column 4 close to the upper end abuts on the movable adjustment plate 51; a decorative cover 6 is also provided on the outer side of the connecting seat 3, which surrounds the connecting seat 3 and the abutting portion 31, and an opening is provided in the decorative cover 6 corresponding to the position of the support column 4.
