Problems solved by technology
[0004] (2) Because the locking handle 13 cannot adjust the left and right angles, and the locking handle needs to be positioned downward against the vehicle frame 16, it must cooperate with the locking of the nut 11 to adjust the locking handle 13 Angle, very troublesome and time-consuming
[0005] (3) In particular, the linkage rod 12 is directly screwed into the screw hole 101 of the lock force lever 10. After the lock force lever 10 is locked, the linkage rod 12 is still connected to the lock force lever 10, so there will be a "lock force handle 13". Turning by mistaken touch" and "vibration during driving" cause the linkage rod 12 to malfunction and make the locking rod 10 loose, which is not safe
[0006] ⑷The positioning seat 15 has no reinforcing structure, and its endurance strength is poor

The invention discloses a quick release structure for a bicycle, which comprises: a locking lever, a linkage lever, a positioning seat, a connecting head, and a locking handle; The rod is combined into the locking rod, and one end of the locking rod has an external thread and is locked to the frame; wherein, the other end of the locking rod is provided with a screw hole, and a polygonal groove is provided in the screw hole; the locking rod A bolt with a through hole is set in the screw hole, the bolt passes through the positioning seat, and the linkage rod passes through the through hole of the bolt. The polygonal groove of the locking lever forms a rotatable locking lever, and also enables the linkage lever to retreat to disengage the polygonal head from the polygonal groove to form a non-rotatable locking lever. The polygonal head of the linkage rod can be inserted into or retreated from the polygonal groove of the lock handle, so that the lock handle can rotate or cannot be rotated, so the linkage rod of the lock handle will not have the problem of accidentally loosening the lock lever due to vibration, which is safe sex increased.
Description
technical field [0001] The invention relates to a bicycle quick-release structure. The locking lever and the linkage lever of the bicycle quick-release structure can be connected and linked when they need to be rotated to lock and loosen. After locking, the locking lever is separated from the locking lever. Therefore, the locking bar will not be loosened due to vibration, so that the safety effect can be achieved. Background technique [0002] Existing bicycle quick release locking force structure is generally all the same figure 1 , 2 Shown, be that a locking force bar 10 wears and assembles on the axle, and its one end is provided with nut 11 and locks on vehicle frame 16, and the other end is provided with interlocking bar 12, locking bar 13, positioning seat 15, and interlocking bar 12 and The combined structure of the locking handle 13 is set so that the linkage rod 12 has a connecting head 14 and is eccentrically combined in the locking handle 13. When the locking ha...
