[0020] like Figure 1-7 As shown, a baby dining chair includes a seat 1 and a base 2, which are connected by a support column 3, and the support column 3 includes an upper support portion 31, a detour connection portion 32 and a lower support portion 33 of an integrated structure from top to bottom. The upper support portion 31 and the lower support portion 33 are vertically arranged, and the lower support portion 33 is located in front of the upper support portion 31. The bottom of the seat 1 is fixedly connected with a connecting seat 10, the upper end of the upper support portion 31 is fixedly connected to the connecting seat 10, the connection portion between the upper support portion 31 and the connecting seat 10 is located at the rear side of the bottom of the seat 1, and the lower end of the lower support portion 33 is fixedly connected to the base 2; an upper footrest connection portion is provided at a position near the front side of the bottom of the seat 1, and a lower footrest connection portion is provided on the lower support portion 33, and the upper footrest 4 and / or the lower footrest 5 are respectively connected to the upper footrest connection portion and the lower footrest connection portion.

[0021] The upper footrest connecting portion is a card interface 11 opened on the connecting seat 10, and the upper end of the upper footrest 4 is provided with a rotary joint 41 that cooperates with the card interface 11; the card interface 11 is a circular bayonet, and a number of inner card strips 12 are symmetrically distributed on the inner wall of the circular bayonet, and the top surface of the inner card strip 12 is a sloped structure; the rotary joint 41 includes a circular protrusion 42 that cooperates with the circular bayonet, and a number of outer card strips 43 are symmetrically provided on the outer wall of the circular protrusion 42, and the bottom surface of the outer card strip 43 is a sloped structure. When the circular protrusion 42 is inserted into the circular bayonet, the inner card strip 12 and the outer card strip 43 are staggered with each other, and the upper footrest 4 is rotated so that the bottom surface of the outer card strip 43 abuts against the top surface of the inner card strip 12, and the top surface of the inner card strip 12 is provided with a convex rib 13, and the corresponding bottom of the outer card strip 43 is provided with a slot. When the convex rib 13 and the slot cooperate, the upper footrest 4 is clamped to the bottom of the seat 1.

[0022] The lower footrest connecting portion includes an adjustment slot hole 51 that passes through the lower support portion front and back. The adjustment slot hole 51 is long and strip-shaped from bottom to bottom. Guide slots 52 parallel to the adjustment slot holes are provided on both sides of the adjustment slot hole 51 on the front side of the lower support portion 33; a screw hole 53 is provided at a position corresponding to the adjustment slot hole on the back of the lower footrest 5, and a guide block 54 is provided at a position corresponding to the guide slot 52. The adjusting bolt 6 passes through the adjustment slot hole and is screwed on the screw hole 53 to fix the lower footrest 5 to the front side of the lower support portion 33. The guide block 54 is embedded in the guide slot 52 to prevent the lower footrest 5 from rotating; there are two screw holes 53 on the back of the lower footrest 5, one of which is provided with a hand tightening wheel 61 at the nut end of one of the bolts 6, and the hand tightening wheel 61 can completely cover the end of the other bolt.

[0023] The utility model adopts a vertical arrangement of the support column that originally tilted backward. In order to ensure the stability of the seat, the support column is composed of an upper support part, a detour connecting part and a lower support part of an integrated structure from top to bottom, wherein the upper support part and the lower support part are vertically arranged and distributed front to back, and the detour connecting part is used to connect the upper support part and the lower support part into one body. The vertical arrangement of the upper support part and the lower support part facilitates the processing and installation of the base and the seat connecting part. At the same time, considering that the position of the upper support part is moved backward, a footrest cannot be set, so that younger babies have shorter legs and cannot step on the footrest. For this reason, the utility model adopts an upper and lower double footrest structure. The upper footrest structure is adopted for younger babies, and the lower footrest structure is adopted for older babies who have grown taller, and the lower footrest can be adjusted up and down to meet the needs of children of different age groups. It has the characteristics of reasonable structure, adjustable footrest and good comfort.
