It is a travel method that saves energy, improves energy efficiency, reduces pollution, is beneficial to health, and takes efficiency into consideration. Therefore, more and more people choose to travel by bicycle or scooter. However, there is no basket on scooters and some bicycles, which makes it difficult for riders to put their belongings and inconvenient to ride. An additional basket needs to be installed. The existing baskets are all installed with screws, which is not only troublesome to disassemble and assemble, but also easy to lose. Summary of the invention

[0003] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a combination lock, which is used to install a storage basket, facilitates the disassembly of the storage basket, and can play an anti-theft effect.

[0004] The technical solution of the utility model is as follows: a password lock comprises a mounting frame connected to a vehicle frame and a lock body, the lock body being arranged on the mounting frame, the lock body comprising a lock shell, a lock shaft, a password wheel, a lock tongue and an unlocking piece, the lock shell being connected to the mounting frame, the lock shaft and the password wheel being arranged in the lock shell, the password wheel being rotatably sleeved on the lock shaft, and the password wheel being partially exposed outside the lock shell, the lock tongue being arranged at the end of the lock shaft, and being connected to or integrally arranged with the lock shaft, a through groove for the lock tongue to enter and exit is provided on the mounting frame corresponding to the position of the lock tongue, the unlocking piece is slidably arranged on the lock shell, and is connected to the lock tongue or the lock shaft so as to drive the lock tongue to enter and exit the through groove, a reset spring is also sleeved on the lock shaft, the lock tongue extends from the through groove under the action of the reset spring, the storage basket is plug-in-matched with the mounting frame, and is locked with the mounting frame under the action of the lock tongue.

[0005] By adopting the above technical solution, a lock opening is provided on the storage basket. When the storage basket is plugged into the mounting frame, the lock opening corresponds to the through slot. The combination lock is placed on the vehicle frame through the mounting frame, and the storage basket is plugged into and matched with the mounting frame. The lock tongue extends out of the through slot and is inserted into the lock opening on the storage basket to lock the storage basket. When the storage basket needs to be removed, the combination wheel is turned to the correct combination, and then the unlocking piece is slid to drive the lock shaft and the lock tongue to slide. The lock tongue sequentially exits the lock opening and the through slot. At this time, the storage basket can be removed from the mounting frame. After releasing the unlocking piece, the reset spring automatically resets the lock tongue, and the storage basket is locked by the combination lock to prevent theft. In addition, the storage basket is convenient and quick to disassemble and assemble, and can be disassembled and assembled by oneself according to usage requirements.
