[0019] As shown in the figure, a foldable children's chair, including chair back 1, seat plate 2 and chair leg 3, the chair back 1 with the seat plate 2 rear articulation connection, the chair back 1 bottom is equipped with first hollow groove 4, the bottom end of first hollow groove 4 front side wall is equipped with first narrow edge 5, the upper surface of the rear position of seat plate 2 is equipped with the convex part 6 of first narrow edge 5 contact cooperation, the chair back 1 has the vertical state when first narrow edge 5 does not cross the convex part 6 and the horizontal state after first narrow edge 5 crosses the convex part 6;The technical scheme is through setting the convex part in the rear part of seat plate, makes first narrow edge contact convex part, when needing to fold the chair back, can exert force to the chair back, makes first narrow edge cross the convex part, thereby makes the chair back fold into horizontal state, the chair back and seat plate of folding chair are completely attached, and thickness reduces 60%, is convenient to put into narrow space (such as car trunk), is convenient to store, and practicality is good.

[0020] The convex part 6 left and right sides are equipped with the through strip slot 7, when first narrow edge crosses the convex part, will make the convex part occur elastic deformation, and the strip slot can make the convex part bear a certain degree of elastic deformation.

[0021] The convex part in the embodiment has multiple embodiments;

[0022] Embodiment one: the convex part and the strip slot on the two sides of the convex part are integrally injection molded with the seat plate, and the plastic material has elasticity and can bear appropriate elastic deformation.

[0023] The convex part adopts elastic buffer pad (such as rubber block), and the mounting mode can adopt bonding or bolt fixing; when the chair back is folded, the buffer pad is in contact with the chair back, and the buffer pad is elastically deformed.

[0024] The convex part 6 is arc-shaped and balancedly connected on the front and back sides, the first narrow edge part 5 is provided with a rounded corner 8, has the advantages of smooth folding, not easy to be blocked, reducing friction loss and prolonging service life.

[0025] The rear part of the seat plate 2 is provided with an arc-shaped avoiding surface 10 for the bottom of the chair back 1 to rotate, the chair back is connected with a bolt, the bolt penetrates through the two sides of the seat plate, the rotating installation of the chair back is realized, and the arc-shaped avoiding surface can prevent the chair back from being blocked when rotating.

[0026] The rear part of the arc-shaped avoiding surface is further provided with a second hollow groove 11, the top end of the rear side wall of the second hollow groove 11 is provided with a second narrow edge part 12, the bottom end of the rear side wall of the first hollow groove 4 is provided with a third narrow edge part 13, the second narrow edge part 12 and the third narrow edge part 13 are in contact with each other when the chair back 1 is in the vertical state, the chair back cannot rotate backward any more, the vertical state is stable, the chair back is locked firmly in the vertical state, and the chair back is prevented from being accidentally folded when a child leans backward.
