The first rotating ring 22 is sleeved on the outer periphery of the rotating shaft 10, so that the first rotating ring 22 can It is accommodated in the cap 21, and one side of the cover 23 facing the cap 21 has a wall 231. The inner edge of the cover 23 has an internal thread portion 232, and the cover 23 is sleeved. It is arranged on the outer periphery of the rotating shaft 10, so that the cover 23 can be screwed with the cap 21; an anti-theft component 30, which is composed of a hollow positioning ring 31, a hollow lock 32, a positioning The rotating rod 33, a hollow second rotating ring 34, a retaining post 35, and a plug member 36 with an accommodation hole 361, the positioning ring 31 has a tooth surface 311 facing one side of the cover 23, and the The inner edge of the positioning ring 31 has an internal thread portion 312, and the lock head 32 has an external thread portion 321 with respect to the outer periphery of the internal thread portion 312 of the positioning ring 31, and the outer periphery of the lock head 32 There is a radial through hole 322, and the lock head 32 can receive the positioning rotating rod 33 and the second rotating ring 34 inside. The center of the positioning rotating rod 33 has an internally threaded hole 331, and the positioning rotating rod 33 A plurality of positioning grooves 332 are arranged at equal intervals on the outer periphery, and the positioning ring 31 and the second rotating ring 34 are passed through one end of the rotating shaft 10, so that the outer thread portion 11 of the rotating shaft 10 can be screwed on the positioning rotating rod. 33 is an internally threaded hole 331, and the stopper 35 is installed in the receiving hole 361 of the plug 36, and the plug 36 is fixed in the radial through hole 322 of the lock 32, so that the stop 35 It can be accommodated in the positioning groove 332 of the positioning rotating rod 33 in a normal state.

The operation portion 12 is a hexagon socket.

Wherein, two sides of the first swivel ring 22 and the second swivel ring 34 are respectively provided with a lining 40.

It may further include a hollow fixing ring 37, and both sides of the fixing ring 37 have a tooth surface 371 and a blocking piece 372, respectively, and the tooth surface 371 can be engaged with the tooth surface 311 of the positioning ring 31 (such as the first 7), and the blocking piece 372 of the fixing ring 37 can be received in one of the notches 61 of the fork pipe 60.

With the combination of the above, please continue to refer to the first to sixth figures. This creation is a quick-release anti-theft structure for bicycles, which is especially suitable for quick disassembly and assembly of the hub 50 mounted on the fork pipe 60. For use, the fork pipe 60 may be a front fork pipe or a rear fork pipe.

Generally, two ends of the flower hub 50 have a convex rod portion (not shown in the figure), and the two convex rod portions can be respectively accommodated in the gaps 61 of the fork tube 60; it is worth noting that this creation The quick-release anti-theft structure can be pre-assembled with the flower hub 50, that is, the outer thread portion 11 of the rotating shaft 10 is used to sequentially pass through the first rotating ring 22 and the cover 23, and the cover 23 is screwed on the cap 21, Then, the rotating shaft 10 is used to pass through the positioning ring 31 and the second rotating ring 34, and the external thread portion 11 of the rotating shaft 10 is screwed into the internal thread hole 331 of the positioning shaft 33, and the external thread portion 321 of the lock 32 is used. The screw is provided on the internal thread portion 312 of the positioning ring 31. After that, the user can accommodate the protruding rod portions at the two ends of the flower hub 50 in the notch 61 of the fork tube 60, and at the same time, make the cover 23 cover. 230 fits into one of the notches 61 of the fork pipe 60. After that, the user can use a hexagonal wrench (not shown) to insert the operating portion 12 of the rotating shaft 10 and pull the hexagonal wrench to rotate the rotating shaft 10 synchronously. Displacing the positioning rotating rod 33 toward the cover 23 finally makes the tooth surface 311 of the positioning ring 31 abut against the side edge of the fork pipe 60 (please refer to the sixth figure for cooperation) (Shown), so that the quick assembly of the hub 50 is completed, The overall operation is simple and convenient, and it is convenient and practical.

Under normal conditions, when a user does not have a tool such as a hexagon wrench, since the outer peripheral edge of the operating portion 12 of the rotating shaft 10 is additionally equipped with an arc-shaped cap 21, the cap 21 cannot be held by other hand tools, effectively preventing damage and Rotate the rotating shaft 10 and the blocking post 35 of the anti-theft component 30 abuts against the positioning groove 332 of the positioning rotating lever 33 (as shown in the fourth figure). The positioning groove 332 of the positioning rotating rod 33 prevents the positioning rotating rod 33 from being rotated, and even moves forward and backward, so it can effectively achieve the effect of anti-theft and security, and it has deep safety and practicality.

When the user wants to remove the hub 50, he only needs to turn the fork pipe 60 upside down (that is, the entire frame body is turned 180 degrees), so that the stopper 35 can be separated from the positioning groove 332 of the positioning rotating rod 33. And falling into the receiving hole 361 of the plug member 36 (as shown in the fifth figure), the user can use a hexagon wrench to rotate the rotating shaft 10, so that the positioning rotating rod 33 can be rotated and further away from the direction of the cover 23. The displacement achieves the purpose of opening the anti-theft component 30, and the positioning ring 31 is in a loose state, so that the user can easily remove the hub 50 from the slot 61 of the fork pipe 60. The overall disassembly method is easy and convenient It is convenient for users to assemble and use DIY.

In summary, the quick-release anti-theft structure of this creative bicycle effectively improves the various shortcomings of the conventional structure, and the main technical means of this creative work have not been found in any relevant publications, which is in line with the application requirements for new patents. An application is filed in accordance with the law, and the Bureau is kindly requested to grant this creative patent right.
