Description

Bicycle quick release actuation positioning structure

The invention relates to a bicycle quick-release actuating positioning structure, which enables the bicycle quick-release locking bar to be directly locked to the frame, and the locking force of the actuating locking bar can be adjusted to adjust the angle, so that the bicycle is kept in a non-touching manner. The frame and the abutment are positioned on the frame.

Check, the bicycle quick release lock structure of the conventional, generally shown in Figures 1 and 2, is a locking rod 10 worn on the axle, one end of which has a nut 11 and is locked to the frame 15, and the other end is linked The combination of the rod 12, the locking handle 13, the linkage rod 12 and the locking handle 13 is configured such that the linkage rod 12 has a coupling head 14 and is eccentrically coupled to the locking handle 13 when the locking lock is forced to the handle 13 When the action is performed downwards and upwards, the linkage rod 12 and the lock rod 10 can be operated to achieve the purpose of tightening and relaxing the lock; the above structure has the following disadvantages:

(1) The combination structure of the lock handle 13 and the linkage rod 12 is configured such that the joint head 14 is directly worn on the lock handle 13 so that the lock handle 13 can only be turned up and down, and the left and right angles cannot be adjusted. The nut 11 is required to be assisted in locking, and the nut 11 has a problem of being loosened and loosened due to vibration.

(2) The locking handle 13 cannot adjust the left and right angles, and the locking handle needs to be positioned in the downward direction to be positioned on the frame 15, so that it must be locked with the locking of the nut 11 to adjust the locking handle 13 The angle is extremely troublesome and time consuming.

The present invention is to improve the above-mentioned shortcomings, and the main technical and purpose is to combine the interlocking rod and the locking handle of the locking rod, and the interlocking rod has a ring groove and a stopper, and the connecting head is provided with the stopper 27. The ring groove of the linkage rod 22 forms a lock handle to rotate and adjust the angle, and directly rotates the lock lever. Therefore, the lock lever can be directly locked to the screw hole of the frame without the nut, so that the lock can be quickly locked. The problem of tight relaxation and no loosening of the nut, and the locking handle can be adjusted to an angle that does not touch the frame, and is positioned against the frame.

Referring to FIG. 3, FIG. 4, FIG. 5 and FIG. 6, the locking bolt 20 has an external thread 21 at one end and is directly locked to the screw hole 16 of the frame 15. The other end of the locking rod 20 is provided with a linkage rod 22 and a locking handle. 25, the combination of the linkage rod 22 and the locking handle 25 is configured such that the eccentric hole of the locking handle 25 has a coupling head 26 connecting the linkage rod 22, the linkage rod 22 is provided with a ring groove 23, and the ring groove 23 is provided with a stopper 24 Further, the coupling head 26 is provided with a stopper 27 that abuts into the annular groove 23 of the interlocking lever 22.

With the above structure, its function and efficacy are explained as follows:

(1) As shown in FIG. 6, the connecting head 26 of the locking handle 25 is provided with a stopper 27, which can be blocked by the stopper 24 of the interlocking lever 22, thereby rotating the locking handle 25 and the rotating linkage rod 22 and The locking rod is locked, so that the locking rod can be directly locked to the screw hole 16 of the frame 15, and the nut can be loosened without the nut being loosened. Moreover, directly locking the lock lever can obtain a stronger locking force and can achieve the locking effect more quickly.

(2) As shown in FIG. 5, when the lock lever is locked, if the lock handle 25 touches the frame, since the linkage rod 22 is provided with the ring groove 23, the lock handle 25 can be rotated by the rotation angle. The adjustment is not to touch the frame, and the abutment is positioned on the frame 15.

In summary, the structure of the present invention does have excellent practicality and enhanced efficacy, and is in line with the gist of the patent law, and is therefore required to grant a patent.

Claims (1)

The utility model relates to a bicycle quick-release actuation positioning structure, wherein one end of the locking bar is locked to the frame, and the other end of the locking bar is provided with a linkage rod and a locking handle, and the combination of the linkage rod and the locking handle is set as an eccentric hole of the locking handle. The connecting rod has a connecting rod connecting rod; the connecting rod is provided with a ring groove, and the ring groove is provided with a stopper; and the connecting head is provided with a stopper, and the blocking block is inserted into the ring groove of the linking rod to form Let the lock force the handle to adjust the angle and block the lock handle; with the above structure, when the lock handle is blocked, the linkage rod and the lock rod can be directly rotated, and the lock rod lock is forced to be tight when the lock is completed. When it is tight, the lock handle can be adjusted to not touch the frame, and the anchor is positioned on the frame.
