Technical Field
[0001] This utility model relates to the field of dining chair technology, and more specifically, to a children's dining chair that is easy to disassemble. Background Technology
[0002] With social progress and development, a dining chair suitable for children to sit down and eat has been developed to help children develop good sitting habits from an early age. This avoids the trouble of parents chasing after their children to feed them, and can also train children's sitting posture, which helps their physical development.
[0003] Utility model patent CN221785826U discloses a chair, including a bottom support frame, a seat detachably connected to the bottom support frame, a backrest detachably connected to the seat, and a tray assembly detachably connected to the backrest. When used as a high chair, the seat is first installed onto the bottom support frame, then the backrest is installed onto the seat, and finally the tray assembly is installed onto the backrest. The chair can then be used as a high chair for infants and toddlers to eat. Removing the tray assembly from the backrest allows it to be used as a regular chair, convenient for infants and toddlers. This chair can be switched between a regular chair and a high chair, broadening its applicability. Furthermore, for ease of packaging and installation, all components are designed to be detachable, facilitating disassembly, assembly, and transportation.
[0004] Although the existing technology solves the problem that most existing children's high chairs are inconvenient for daily use, and the seat is detachable, the detachability of the seat uses components such as locking components, locking components, and locking components. For example, the locking component includes a locking position on the seat, a locking member on the bottom support frame that can slide relative to it and engage or disengage from the locking position, an unlocking member on the bottom support frame that can slide relative to it and push the locking member out of the locking position, and an elastic member between the locking member and the bottom support frame that can push the locking member back to its original position. These components are relatively complex and are still not very convenient to disassemble. Utility Model Content
