The invention discloses a bicycle folding joint with an improved structure, which comprises a first joint, a second joint and a handle, wherein the first and the second joints are coaxially hinged; the handle is fixedly connected with the hinged shaft of the first and the second joints; the first joint is provided with a first slider, the second joint is provided with a first groove, and the handle can drive the first slider on the first joint to slide in the direction vertical to the hinged shaft to extend into the first groove of the second joint; and the second joint is further provided with a second groove, the first joint is further provided with a second slider and a driving block, and the driving block can move synchronously with the first slider and can further drive the second slider to extend into the second groove of the second joint. Due to the two pairs of engaging structures of the first and the second joints, the connection strength and stability of the first and the second joints are improved; and the folding structure can still work even one of the engaging structures is broken, so that the safety of a user is ensured.
Description
technical field [0001] The invention relates to a bicycle folding joint, in particular to a bicycle folding joint with improved structure. Background technique [0002] Folding bicycles are more and more popular because they are convenient to fold, store and carry. At present, there is only one card interface for bicycle folding joints to be connected. The connection strength and stability are poor. Risk of failure of the folding device due to snapping structure breakage. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a bicycle folding joint with an improved structure. The structure of the bicycle folding joint with the improved structure is strong and the connection is stable. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: a bicycle folding joint with improved structure, including the first and second joints and the handle, the first and second...
