Claims

[Scope of Claim for Utility Model Registration] Regarding a coupling device that is installed on a bicycle body and folds the bicycle in half, the coupling portion is provided with a coupling hinge portion and a coupling tightening portion spaced apart from each other on the left and right sides,
The hinge part on one side is pivoted on a vertical axis and rotates around the axis to be bent and connected, and the connecting tightening part on the other side is divided into upper and lower parts and faces each other, and the upper and lower parts are connected to each other. In a coupling device in which a lock screw is inserted and tightened into a drilled lock hole and a lock screw hole to be locked in a fixed connection state, the lock hole of the upper connection tightening part is opened on the side, The connection tightening part and the lock screw are provided so as to engage when tightening, and when the lower end of the lock screw is screwed into the lock screw hole on the lower side in an upright state, the lock is released and the bending rotation of the connector is prevented. A locking device for a connector in a folding bicycle body. The lock hole of the upper lock side connection tightening part is provided in a slot opened on the side,
An engaging protrusion is formed on the upper surface of the tightening part to protrude to an appropriate height around the groove, and an engaging ring formed on the lower surface of the locking screw head is fitted into this engaging protrusion, and is locked when tightened. A locking device for folding bicycles. The locking hole of the upper connection tightening part is provided in a slot that is opened on the side, and a recess of an appropriate depth is formed around the slot on the top surface of the tightening part, and the head of the locking screw is inserted into this recess. A locking device for a folding bicycle, characterized in that the locking devices fit and lock when tightened. The locking hole of the upper connection tightening part is provided in a slot with an opening narrower than the screw diameter, and the locking screw to be inserted into this hole is provided with the required length in the flat part just below the head, and the locking screw is inserted into the slot with the required length just below the head. A locking device for a folding bicycle, which passes parallel to a loosening opening and can move in and out of the slot, and when tightened, crosses the flat parts and engages in the slot to lock the lock.
