Bicycle quick release structure

The present invention relates to a bicycle quick release structure, in particular to a positioning structure capable of adjusting the interlocking or separating state between the quick release handle head and the mandrel, the movement is clear and convenient to operate, the components are simple, the assembly is convenient, and Simple in function and low in cost.

Bicycles can be used as a means of leisure fitness or transportation, and have the environmental protection effect of energy saving and carbon reduction, which is widely favored by the public. In order to facilitate the disassembly of the wheels, most bicycle structures currently have a quick-release structure in the front and rear wheels, which allows the user to quickly combine and detach the wheel and the frame, and reduce the overall volume. Easy to carry or store.

The quick release structure of a common bicycle includes a shaft that is placed on the axle, a quick release handle that is pivotally connected to one end of the shaft, a nut that is screwed to the other end of the shaft, and is placed on the shaft. In one of the upper seats, the quick release handle has a joint head and is eccentrically pivoted to one end of the shaft, and the lock can be tightened or relaxed by turning the quick release handle to reduce or widen the distance between the nut and the socket. The purpose. However, when the distance between the nut and the socket is tightly adjusted, the quick release structure needs to be adjusted to lock the nut, and the pressing force can only be checked by turning the quick release handle joint, so usually It is necessary to adjust the inspection several times until the correct distance and the pressing force are reached, which causes inconvenience in use, and when locked, it is easy to cause the quick release handle to be loose due to the accidental touch of the quick release handle or the vibration in the drive. It causes the looseness of the components or the separation of the wheels from the frame, which affects the safety of driving.

The manufacturer provides a quick release structure that can adjust the quick release handle and the shaft to be detached, and can rotate the quick release handle to an appropriate position without loosening the shaft due to accidental contact or vibration, so as to achieve safety effect. .

The quick-release structure that can be adjusted between the quick-release handle and the shaft can be divided into two types: the toggle type and the push type.

According to the conventional bicycle quick release structure, the "multi-angle quick release structure" disclosed in the domestic patent No. 102148919 includes: a positioning seat, a lock lever, a linkage rod, a limit sleeve, and a reinforcement a threaded sleeve, a joint head and a lock handle; the linkage rod and the joint head are coupled and combined in the lock handle, and one end of the lock rod has an external thread screw nut and is locked to the frame; wherein the lock rod is further One end is provided with a large circular diameter connecting head, and the locking rod is worn by the group positioning seat to form a linkage head that is engaged with the front end of the positioning seat, and the linkage rod is assembled into the linkage head, and the linkage head is provided with a plurality of convex blocks, and the linkage rod is provided There is a plurality of grooves; the interlocking head of the locking bar has a limiting sleeve of a through hole, and the limiting sleeve is further assembled into the reinforcing screw sleeve, the reinforcing screw sleeve is provided with an external thread, and the positioning seat is provided with an internal thread Mutually screwing, the linkage rod passes through the through hole of the limiting sleeve and the reinforcing nut sleeve; the locking handle can advance the linkage rod, and the groove is fitted with the protrusion of the linkage head to form a rotatable locking rod Alternatively, the rod can be retracted to disengage the groove from the projection to form a non-rotatable lock lever.

Another conventional quick-release structure for a push-type adjustment, such as the quick-release device and the wheel that is particularly suitable for a bicycle, as disclosed in the Japanese Patent No. 095148435, which comprises a pull rod extending in the axial direction, one in the An end member at the first end of the pull rod, a clip at the second end of the pull rod, and a tensioning device for tensioning the clip, wherein the tensioning device includes a a control rod for applying a clamping force and a tension sleeve having a conveyor portion for transmitting a clamping force to one of the engaging portions of the clip, the tension sleeve The barrel includes at least one inwardly extending shoulder for supporting one end of the at least one biasing spring, wherein the lever is positioned to move relative to the clip in an axial direction of the rod, and the lever is rotatable to the lever The axial direction moves outwardly against the biasing force of a biasing spring, moving from an engaged position to a rotational position, wherein an angular position of the control lever can be set without being restrained by the tensioning state.

In the above-mentioned structure, the former pivotally connects one end of the linkage rod with the lock handle, and the other end of the linkage rod is provided with a plurality of grooves, one end of the lock rod is locked with the nut, and the other end of the lock rod is interlocked a head, the linkage head is provided with a plurality of bumps, and by rotating the lock lever to force the linkage rod to advance, and the groove is engaged with the protrusion, the lock lever can be rotated, which can also make the linkage rod retreat, so that The groove is separated from the protrusion, that is, the locking bar cannot be rotated; the latter connects one end of the pulling rod with the clamping member, the other end of the clamping member is sleeved with the tensioning sleeve of the tensioner, and the clamping member and the tensioning sleeve are disposed. The engaging portion has a biasing spring disposed therein, and when the clamping member and the tensioning sleeve are engaged with each other, the lever is rotated to rotate the lever, which can press the head of the safety bolt and simultaneously pull the lever. The lever can move relative to the clamping member in the axial direction against the biasing force of the biasing spring, and moves from the engaged position to the rotating position, that is, the lever cannot be rotated, and the lever can be adjusted in an untensioned state. position.

However, regardless of the flip-type or push-type quick release structure, in order to make the lock lever (tension control lever) and the lock lever (pull rod) out of the interlocking state, it is necessary to continuously pull or press the force to adjust the lock handle. (tensioning the lever) until the predetermined angular position can not apply force. If the groove and the bump or the clip and the tension sleeve are not completely disengaged, and the disengaged state is unclear, the locking lever will still be The pull rod) rotates, causing malfunction, and the latter components are complicated and complicated, assembly is difficult, and the overall structure is easily broken due to damage of one component, resulting in an increase in cost, and the overall structure is necessary for improvement.
