Folding device

The present invention mainly discloses a folding device, and more particularly to a folding device for a folding cart, which can be installed between a frame of a folding bicycle and a handle riser, so that the frame and the handle riser can be selectively pivoted relative to each other. Or fixed.

A commonly used folding device can be installed between two pipe members and provides a function of selectively pivoting or fixing the two pipe members. Since the folded two pipe members can be reduced in size, whether carried or stored The transportation is extremely convenient, and the usage rate of the folding device is greatly increased. Today's folding bicycles or motorized bicycles/electric bicycles are environmentally friendly and easy to store and carry. The foldable bicycles or electric bicycles are provided with folding devices for folding purposes. .

However, the conventional folding device comprises two coupling members, a shaft member and a quick release group, and the two coupling members are respectively fixed to one end of the two tubular members corresponding to each other by welding or other connection, and the shaft member is pierced. On one side of the two coupling members, the two coupling members can be pivotally folded with each other with the shaft member as an axis, and the quick release group is disposed on the other side of the two coupling members and is connected to the two coupling members. Tightly locked. The quick release set is operable to change between a locked position and a released position, and the quick release group is pivotable when the release member is in the release position. However, when the quick release group is changed from the locked position to the released position, a quick release lever of the quick release group must be firstly rotated and rotated, and the quick release lever needs to be pulled out by the hand and released from the two coupling members to release. The quick release group enables the two coupling members to pivotally fold relative to each other. When the fixing is required, the quick release lever must be reinserted into the two coupling members and the quick release lever is rotated for a plurality of times to be locked and then tightened to obtain a proper engagement force, so that the two coupling members are fixedly connected. The conventional folding device only uses the quick release group to tightly lock the two coupling members and does not provide a better lock and connection strength. Moreover, the conventional folding device not only has a large number of parts, but also has a cumbersome operation during use, which greatly affects the user's feeling of folding the folding car, so that the user gradually loses the interest in using the folding car, which is entirely because the folding device operates.
