[0001] The present invention relates to the technical field of locks, and in particular to a password bicycle lock. Background Art

[0002] In the prior art, in order to advocate green travel, people choose bicycles as means of transportation. Then, for anti-theft purposes, people usually lock bicycles with password locks, which are locked on the wheels of bicycles. However, in this way, the whole bicycle can be directly lifted away, and the anti-theft function still cannot be achieved. Therefore, a password lock cooperating with a chain appears. It includes a lock shell, a password wheel assembly arranged on the lock shell, a lock rod, a core shaft, and a driving member for driving the core shaft to move to achieve unlocking. The password wheel assembly is rotatably arranged on the outer periphery of the core shaft. The lock rod includes at least two rod bodies arranged separately. The ends of the rod bodies extend out of the lock shell and bend. One end of the chain is sleeved on one of the rod bodies, and the other end is sleeved on the other rod body. The driving member drives the core shaft to move, and the chain disengages from the rod body. The chain locks the bicycle to a telegraph pole or a tree trunk. However, for the above-mentioned password lock, the lock rod is arranged separately and is easy to be pulled out from both sides, thus realizing the disengagement of the chain, and the anti-theft function is poor. Summary of the Invention

[0003] Objective of the present invention: In order to overcome the defects of the prior art, the present invention provides a password bicycle lock, the lock rod of which is integrally formed, and the lock rod is prevented from being pulled out from both sides by using limit cooperation, and the anti-theft effect is good.

[0004] Technical solution of the present invention: A password bicycle lock includes a lock shell, a password wheel assembly arranged on the lock shell, a lock rod, a core shaft, and a driving member for driving the core shaft to slide to achieve unlocking. The password wheel assembly is rotatably arranged on the outer periphery of the core shaft. The end of the lock rod extends out of the lock shell. The lock rod includes an integrally formed rod body and first bent portions and second bent portions located at both ends of the rod body and bent towards the lock shell. A limit structure is provided between the lock rod and the lock shell to limit the sliding of the lock rod. The end of the first bent portion extends into the lock shell. The end of the driving member extends out of the lock shell and abuts against the second bent portion. A gap for the chain to enter and exit is formed between the end of the second bent portion and the lock shell. When the driving member drives the core shaft to slide, the driving member separates from the second bent portion to achieve the unlocking of the chain.

[0005] By adopting the above technical solution, the lock rod is integrally formed and is cooperated with the lock shell through a limit structure, preventing the lock rod from being pulled out from both sides, making its structure stable and having good anti-theft performance. Rotate the password wheel assembly. After the password is correct, the driving member moves, pushing the core shaft to slide, so that the driving member separates from the second bent portion. A gap is formed between the driving member and the second bent portion, and the chain can enter and exit the second through hole. When the password is incorrect, the driving member cannot push the core shaft, and the driving member always abuts against the second bent portion, and the chain cannot disengage.

[0006] Further setting of the present invention: An installation groove is provided on the lock case along its transverse direction, the rod body is clamped in the installation groove, the limiting structure includes a plurality of limiting blocks and limiting grooves cooperating with the limiting blocks, each limiting block is arranged on both side walls of the installation groove, each limiting groove is arranged on the outer periphery of the rod body, and each limiting block is clamped in the corresponding limiting groove to limit the rod body from detaching from the lock case.

[0007] With the above further setting, the structure is simple and the installation is convenient. The cooperation of the limiting block and the limiting groove can be used to limit the lock rod from detaching. No matter which side is pulled, it will be blocked, and the anti-theft performance is high.

[0008] Another further setting of the present invention: A locking groove for inserting the first bent portion is provided on the lock case, a clamping block is provided on the side wall of the locking groove, a clamping groove is correspondingly provided on the first bent portion, and the clamping block is clamped in the clamping groove to prevent the first bent portion from detaching from the lock case.
