[0002] Bicycle carriers for vehicles are widely used to provide bicycle carrying capacity to automobiles, and the bicycle carriers are usually installed on vehicle trailer hooks or on roof luggage racks. No matter where the bicycle carrier is installed, it is necessary to conveniently and reliably fix the bicycle to the bicycle carrier.
[0003] Existing bicycle fixing devices achieve three-point fixing by fixing the front and rear tires of the bicycle and a point on the bicycle frame to the bicycle carrying bracket. The conventional practice is to use clamping claws to fix the bicycle to the bicycle carrying bracket. The clamping claws generally consist of two main parts, the first and second claws. When tightened with a tightening device such as a rotating knob, the two clamping claws tighten the bicycle frame pipe beam to fix the bicycle to the carrying bracket.
[0004] However, this type of clamping claw is usually unable to completely wrap around the bicycle frame tube beam, and due to structural reasons, the internal stress is relatively large, and a larger thickness and size are usually required to ensure strength, which is not conducive to users easily fixing the bicycle. For this reason, we provide a cable tie type bicycle fixing device with an anti-theft lock. Summary of the invention
[0005] The purpose of the present invention is to provide a cable tie type bicycle fixing device with an anti-theft lock to solve the problem mentioned in the above background technology that the existing clamping claws are usually unable to completely wrap around the bicycle frame pipe beam, and due to structural reasons, the internal stress is relatively large, and usually a larger thickness and size are required to ensure strength, which is not conducive to users to easily fix the bicycle.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention fixes the bicycle and the carrying bracket by adopting a cable tie type binding structure. When fixing, the ratchet cable tie part is fixed around the position where the automatic bicycle frame beam needs to be fixed, and one end of the ratchet cable tie is inserted into the locking buckle and tightened, which can be initially fixed. In order to further increase the fixing force, the operating buckle can be pulled to push the ratchet cable tie to be tensioned, and under the action of the first torsion spring rotating shaft, the end of the locking buckle can be close to the ratchet cable tie to achieve locking and fixing. When unlocking, the operating buckle is pulled and pressed in the direction of the locking buckle, so that the operating buckle presses the locking buckle downward, forcing the locking buckle to lift and release the ratchet cable tie, thereby releasing the bicycle frame beam. The disassembly and assembly process is convenient and quick, which solves the problem that the existing clamping claw structure is usually unable to completely wrap the bicycle frame pipe beam, and due to structural reasons, the internal stress is relatively large, and a larger thickness and size are usually required to ensure strength, which is not conducive to users to easily fix the bicycle.
