Quick release structure for hidden drive handle

This creation is a quick release structure that can hide the drive handle, which makes the bicycle quick release drive handle, and can be stored in the shaft when it is not needed.

In the conventional bicycle quick release structure, as shown in Figs. 1 and 2, a shaft 10 is simultaneously worn on the bicycle's two forks 1 and the axle 2, and the shaft 10 is provided with an external thread 11 at one end and is locked. In one of the forks 1 , the other end is provided with a screw hole 12 and a linkage rod 13 . The linkage rod 13 has a coupling head 131 and simultaneously wears a locking block 14 and a positioning seat 15 . A ring tooth 151 is disposed on the end surface, and an annular tooth surface 3 is disposed on the outer end surface of the other fork frame 1 to be in contact with the ring tooth 151; the connecting head 131 of the connecting rod 13 is an eccentric pivot group and a driving handle 16 When the driving handle 16 is turned downward and upward, the linkage rod 13 and the shaft 10 can be actuated to achieve the purpose of locking and loosening; the above structure has the following disadvantages:

1. Since the driving handle 16 needs to be evaded after locking, the fork frame 1 can be surely locked and abutted. Therefore, when the shaft 10 is tightened and the axle 2 is locked, the angle of the fork 1 must be matched. Therefore, the angle of the driving handle 16 can be adjusted even more tightly or more relaxed, which is extremely troublesome and inconvenient.

2. The driving handle 16 is an exposed member at any locking angle. Therefore, the shaft 10 is loosened due to "the driving handle 16 is accidentally touched and rotated", and is less secure.

The main purpose of the present invention is to solve the above problems, and to provide a quick release structure capable of concealing the driving handle. The main technical and purpose is that the driving handle passes through the slot of the circular shaft and is worn in the shaft.

The effect of the handle 25.

The composition of this creation, the details are as follows: the composition of the creation, the details are as follows: as shown in Figures 3, 4, 5, and 6, the creation of the handle 25 using the handle 25 is small, the shaft 20 The shaft through hole 21 can be hidden therein, and the cutting groove 232 can accommodate the crown 251 for hiding purposes; when assembled, the screw hole 231 of the round shaft head 23 is screwed into the screw segment 201 of the shaft 20 And sizing at the screwing portion to firmly integrate the round shaft head 23 with the shaft 20, and the latching member 26 When the side hole 233 is screwed into the hole 233, the steel ball 263 can be abutted against the guide groove 253 of the driving handle 25, so that the driving handle 25 can be stabilized without being shaken when being extracted or pushed in, and noise can be avoided; The length of the guiding groove 253 extends from the shank 251 to the end of the shank 252, so that the driving handle 25 can slide back and forth, and the steel ball 263 can be inserted into the first positioning groove 254 or the second of the guiding groove 253. Positioning the groove 255; when the driving handle 25 is pushed into the first positioning groove 254 of the guiding groove 253, the driving handle 25 is not only sucked by the magnetic member 22, the first The positioning groove 254 assists in positioning the driving handle 25 more firmly; when the driving handle 25 is pulled out to abut the steel ball 263 against the second positioning groove 255 of the guiding groove 253, the handle body 252 can be completely separated from the rod through hole 21 The range is so as to be undisturbed by the rod through hole 21, and the steel ball 263 of the latching member 26 is pivoted in the slot 232; the driving handle 25 is made of a ferromagnetic metal material ( For example, iron (Fe), cobalt (Co), nickel (Ni), etc., the magnetic member 22 is a circular magnet, and therefore, the magnetic member 22 has a magnetic The driving handle 25 can be attracted to make the driving handle 25 not protruded. Further, a small convex portion 256 is protruded on either side of the handle 251 to ensure that the circular shaft head 23 can be more protruded from both sides of the handle 251. The flat drive handle 25 can be conveniently pulled by reaching the user's fingers.

Referring to FIGS. 6-8, when the screw 202 is to be screwed or loosened, the driving handle 25 can be applied to be larger than the positioning force of the magnetic member 22 and the first positioning groove 254. Pulling out, the steel ball 263 of the latching member 26 is positioned in the second positioning groove 255, and the driving handle 25 is pivoted by the steel ball 263 to the angle perpendicular to the shaft 20 (as shown in FIG. 6 As shown in the figure, the left and right deflection of the driving handle 25 can drive the shaft 20 to rotate (the shaft 20 is adhered to the round shaft 23), and the outer thread 202 can be screwed. Or relax the bicycle fork 1 to achieve the convenience of rotating the shaft 20 without tools; when the driving handle 25 is used, the driving handle 25 is turned by the steel ball 263 of the clamping member 26 as an axis. At an angle parallel to the shaft 20 (as shown in FIG. 7), and pushed in the direction of the rod through hole 21, the handle body 252 of the driving handle 25 enters the large aperture section 211 of the rod through hole 21. The handle 251 is immersed in the slot 232, and the end of the handle 252 is placed on the magnetic member 22, and the steel ball 263 is again inserted into the first positioning slot 254 (as shown in FIG. 8). The drive handle 25 The driving handle 25 can be hidden in the shaft 20 and the round shaft head 23 by the suction of the magnetic member 22; thus, the driving handle 25 does not need to consider the shaft for the flashing fork 1 The screwing angle of the rod 20 is problematic, and the driving handle 25 is not exposed without the risk of mis-triggering causing the axle 2 to loosen.
