[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1-6 , which is the first embodiment of the present invention, provides an integrated bicycle front fork lock, which includes a frame front fork 1, a base 2 is installed on both sides of the frame front fork 1, the frame front fork 1 runs through the base 2 as a whole, and the top of the base 2 away from the frame front fork 1 is movably connected with a bracket 3, the bracket 3 is hinged to the end of the base 2 away from the frame front fork 1 through a rotating rod 4, and the end of the rotating rod 4 passing through the bracket 3 protrudes from the base 2, and the other end of the rotating rod 4 is provided with a protruding shaft 5, which is fixedly installed on the side of the base 2 away from the rotating rod 4, and a bolt 6 is threadedly connected to the protruding shaft 5, one end of the bolt 6 extends into the rotating rod 4, and the protruding shaft 5 is threadedly connected to the rotating rod 4 through the bolt 6. The bottom of the frame front fork 1 The part is pre-set with mounting grooves for convenient installation of wheels. The base 2 is fixedly mounted on the columnar structures on both sides of the frame front fork 1 and cannot be rotated or moved. The bracket 3 can rotate with the rotating rod 4 as the center under the restriction of the base 2, and release the lock of the wheel when it deflects to the side away from the wheel. The rotating rod 4 can keep synchronous rotation with the bracket 3 when it is not locked. The inner side of the rotating rod 4 is provided with a thread that is compatible with the bolt 6. The bolt 6 can enter the rotating rod 4 and connect with the thread in the rotating rod 4 while being threadedly connected to the protruding shaft 5, thereby fixing the deflection angle of the bracket 3 on the base 2. After the bracket 3 is locked, the rotation of the wheel on the frame front fork 1 will not be affected if the bracket 3 is not disassembled.

[0031] The end of the bracket 3 away from the base 2 is movably connected to a locking rod 7, which runs through the entire bracket 3. The locking rod 7 passes through the bracket 3 and is fixedly installed with a limiting pad 8 at one end close to the protruding shaft 5. The locking rod 7 can move in the hole in the bracket 3, and the limiting pad 8 can limit the maximum moving distance of the locking rod 7, thereby avoiding excessive movement of the locking rod 7 and causing it to fall off.

[0032] A sleeve 9 is also fixedly installed on the side of the bracket 3 close to the protruding shaft 5. The sleeve 9 is located at the end of the bracket 3 away from the rotating rod 4. The end of the locking rod 7 that passes through the bracket 3 is located in the sleeve 9. The end of the locking rod 7 away from the limit pad 8 is respectively fixedly installed with an insertion rod 10 and a docking shaft 13. A spring 11 is provided on the inner side of the sleeve 9. The insertion rod 10 is movably connected to the sleeve 9 through the spring 11. The end of the insertion rod 10 away from the locking rod 7 protrudes from the sleeve 9. The sleeve 9 can limit the movement direction of the insertion rod 10 and the locking rod 7, thereby avoiding angular deviation. When the spring 11 is in an extended state, it pushes the insertion rod 10 to move toward the end away from the locking rod 7, so that the insertion rod 10 protrudes from the sleeve 9 to meet the locking requirements of wheels of different widths.

[0033] One end of the insertion rod 10 protruding from the sleeve 9 is fixedly connected to the plug 12, and the end of the docking shaft 13 away from the locking rod 7 is movably connected to the joint 14. A slot 15 is provided on the inner side of the joint 14, and the slots 15 are distributed in a circular array around the docking shaft 13. The plug 12 is pushed toward the joint 14 by the insertion rod 10 protruding from the sleeve 9. After the plug 12 is docked with the joint 14, the locking rod 7 connected to the insertion rod 10 and the locking rod 7 connected to the docking shaft 13 are in the same straight line. When they are located in the wheel, the wheel can be locked.

[0034] The plug 12 is fixedly installed with U-shaped blocks arranged at equal intervals on one side close to the connector 14. The U-shaped blocks in the plug 12 correspond to the slots 15 one by one. The slots 15 are installed with card blocks that adapt to the U-shaped blocks in the plug 12. The plug 12 can be plugged into the slots 15 in the connector 14 through the U-shaped blocks. After the connector 14 is plugged into the plug 12, it can be rotated on the plug 12, so that the card blocks in the slots 15 are plugged into the U-shaped blocks in the plug 12, thereby completing the docking of the plug 12 and the connector 14.

[0035] One end of the docking shaft 13 close to the connector 14 is movably connected with a threaded swivel 16, and the outer side of the threaded swivel 16 is threadedly connected with a threaded barrel 17. The threaded barrel 17 is movably connected to the outer side of the docking shaft 13. The threaded swivel 16 can rotate synchronously with the connector 14, and the threaded barrel 17 can move in the groove of the docking shaft 13, but cannot rotate. After the threaded swivel 16 is threadedly connected to the threaded barrel 17, the connector 14 connected to the threaded swivel 16 cannot rotate in the docking shaft 13, thereby preventing the connector 14 from rotating in the docking shaft 13 and disengaging from the plug 12, thereby ensuring the stability of the locking.

[0036] When locking is required, the bracket 3 is deflected to the side close to the wheel in the frame front fork 1, and the locking rod 7 in the bracket 3 can maintain the same straight line direction under the restriction of the limit pad 8, pass through the wheel in the frame front fork 1, and push the insertion rod 10 from the sleeve 9 through the spring 11 stretched in the sleeve 9 to adapt to the locking requirements of wheels of different widths. At the same time, after the U-shaped block in the plug 12 is plugged into the slot 15 in the joint 14, the joint 14 is rotated in the docking shaft 13 to make the card block in the joint 14 and the U-shaped block in the plug 12 complete the card connection, thereby completing the docking of the plug 12 and the joint 14, and the threaded ring 16 fixedly installed on the outside of the joint 14 is threaded with the threaded cylinder 17 that slides but cannot rotate on the docking shaft 13. The connection makes the connector 14 non-rotatable in the docking shaft 13, thereby preventing the connector 14 from rotating in the docking shaft 13 and disengaging from the plug 12, ensuring the stability of the lock, and when it is necessary to release the lock, by twisting the bolt 6 in the protruding shaft 5, the bolt 6 and the rotating rod 4 are released from the threaded connection, so that the bracket 3 can rotate with the rotating rod 4 as the center under the restriction of the base 2, and when the bracket 3 is rotated to the side away from the wheel in the frame front fork 1, the bolt 6 is re-entered into the rotating rod 4, and is threadedly connected with the protruding shaft 5 while entering the rotating rod 4 and connecting with the thread in the rotating rod 4, thereby fixing the deflection angle of the bracket 3 on the base 2, and then after the bracket 3 is locked, the rotation of the wheel on the frame front fork 1 will not be affected if the bracket 3 is not disassembled.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
