The front end of the seat plate is bent downwards with a large radius. The seat plate cross brace is fixed to the back of the bend. The two ends of the seat plate cross brace are provided with inner plug nuts. The rear end and both sides of the seat plate are bent downwards at right angles. Self-tapping screw holes are provided on the bend edges.

[0006] The backrest leg assembly consists of a backrest leg bend tube, a chair cross brace, a backrest leg center brace, and a chair back panel. The backrest leg bend tube is a door frame shape with an open lower end, and the two vertical arms serve as chair legs. At the bend in the middle of the backrest leg bend tube, each of the two chair legs has two vertically arranged first and second connecting holes, which are used to connect and fasten the chair leg assembly. The chair cross brace is located at the lower part of the bend in the backrest leg bend tube, and its two ends are welded to the two chair legs of the backrest leg bend tube. The two ends of the backrest leg center brace are welded to the bend in the middle of the two chair legs of the backrest leg bend tube. The chair back panel is fixed to the backrest leg center brace and the backrest leg bend tube above the backrest leg center brace, and covers the space formed by the backrest leg bend tube and the backrest leg center brace.

[0007] The two chair leg assemblies are divided into a left chair leg assembly and a right two chair leg assembly. The left chair leg assembly and the right two chair leg assembly are completely identical, including an L-shaped chair leg and an L-shaped fixing member. The rear end of the L-shaped chair leg is provided with an inner plug nut and the lower end is plugged with a plug. The horizontal arm of the L-shaped fixing member is fixed below the rear end of the L-shaped chair leg, and the vertical arm is provided with a self-tapping screw hole for connecting with the back leg bend tube.

[0008] To further achieve the purpose of this utility model, the L-shaped chair leg may include a crossbeam, a vertical leg, and a connecting bend. The two ends of the connecting bend are respectively inserted into one end of the crossbeam and one end of the vertical leg. An inner plug nut is provided in the other end of the crossbeam, and a plug is inserted into the lower end of the vertical leg.

[0009] Compared with existing technologies, this utility model has the following significant features and positive effects: This utility model uses a seat cross brace assembly, back leg assembly, chair cross brace, and two chair leg assemblies connected together by bolts to form a detachable structure. This structure is simple, easy to disassemble and install, and safe and comfortable to use. Furthermore, each component in the seat cross brace assembly, back leg assembly, chair cross brace, and two chair leg assemblies is composed of different parts connected by bolts, further forming a detachable structure, enhancing the flexibility of disassembly and assembly and making it more convenient to carry. After assembly, the upper surface of the seat is horizontal, the two front legs are vertical, and the two back legs are bent backward at a certain angle, creating structural stability. This makes the product highly practical, safe, reliable, and aesthetically pleasing, making it a popular and ideal children's product. Attached Figure Description
