Folding mechanism and folding trolley

Abstract

The embodiment of the invention discloses a folding mechanism and a folding trolley. The folding mechanism comprises a foundation base, a rotation assembly, a movable base, a bayonet lock, a torsion elastic part and a linear elastic part; a rotation groove is formed in the middle of the foundation base, a first insertion groove and a second insertion groove are formed in the groove bottom wall andone groove end wall of the rotation groove respectively, and a first locking groove and a second locking groove are formed in the groove side walls of the rotation groove respectively; the bottom ofthe movable base is inserted in the rotation groove, the top of the movable base is fixedly connected with the bottom of the rotation assembly, a pivot penetrates through the two groove side walls ofthe rotation groove and the movable base, long strip holes for the pivot to pass through and slide relatively are formed in the movable base, and a plug is arranged at the bottom of the movable base;the bayonet lock is relatively fixedly connected with the bottom of the rotation assembly in the axial direction and is relatively movably connected with the bottom of the rotation assembly in the circumferential direction, and the baronet lock is correspondingly clamped into the first locking groove and the second locking groove separately; the torsion elastic part promotes the baronet lock to bemaintained in the first locking groove, and the linear elastic part promotes the plug to be maintained in the first insertion groove or the second insertion groove. The folding mechanism folds or spreads the rotation assembly conveniently and easily, and is stable and good in structural performance.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of folding bikes, and in particular to a folding mechanism and a folding bike. Background technique [0002] Folding bicycles are favored by consumers for their features of reducing the space occupied by folding when not in use and making them convenient for storage. Existing folding bicycles are usually equipped with folding mechanisms at the standpipe, main frame, etc. to realize folding. An existing folding mechanism mainly includes: a base fixedly connected to the first member of the folding cart, a rotating member pivotally connected to the base at one end, and used to fix the rotating member when the rotating member is in an unfolded position. The cam-type quick release lock of the member and the buckle that fixes the rotating member when the rotating member is rotated to the stowed position. This kind of folding mechanism is provided with cam-type quick-release locks and bu...

AI Technical Summary

Problems solved by technology

This kind of folding mechanism is equipped with cam-type quick-release locks and buckles to fix the rotating components in different states respectively. The structure is relatively complicated and the operation is also inconvenient.
