AI Technical Summary

Technical Problem

Existing strollers, high chairs, and other products have complex folding joint structures, numerous and bulky parts, making assembly inconvenient and failing to meet portability requirements.

Method used

It adopts a simplified folding joint structure, including a first rotating seat, a second rotating seat, a locking component, a linkage component, and an unlocking component. Through the synergistic action of the elastic component and the unlocking component, the locking component can be unlocked and locked, simplifying the stacked design, reducing the thickness, and improving convenience.

Benefits of technology

It achieves a compact and lightweight folding joint, reduces material costs and assembly difficulty, improves folding smoothness, facilitates one-handed operation, reduces folded volume, avoids the risk of children's fingers getting pinched, and is suitable for children's products that are frequently stored.

Abstract

The application discloses a folding joint structure, comprising: a first rotating seat and a second rotating seat connected in rotation; a locking piece movably mounted in the first rotating seat and moving in a plane perpendicular to the rotating shaft, and provided with a first elastic piece between the first rotating seat; a linkage piece axially movably mounted between the first rotating seat and the second rotating seat, and provided with a second elastic piece between the second rotating seat; an unlocking piece arranged on the first rotating seat and used for pushing the linkage piece to move; in the unfolded state, the locking piece is simultaneously clamped in a first locking groove of the first rotating seat and a second locking groove of the second rotating seat, the linkage piece is in a locking position, and the locking piece cannot be unlocked; when unlocking, the linkage piece is driven to move by the unlocking piece to move away from the locking position, and then the unlocking movement of the locking piece is allowed or the unlocking movement of the locking piece is driven; the application reduces the thickness of the folding joint through the structural improvement, greatly simplifies the laminated structure design, and makes the whole more compact and light.
