[0002] Non-motorized riding vehicles such as bicycles, electric bicycles, and motorcycles are common means of transportation for people traveling outside. They have been widely used worldwide for a long time in the past, bringing a lot of convenience to people's travel. Their market share is getting higher and higher, but at the same time, they also bring certain safety hazards. In recent years, the phenomenon of bicycle theft has been very common, and most of them are stolen. To prevent theft, lock manufacturers have introduced some anti-theft bicycle locks. The chain lock is one of the bicycle locks, which is mainly used to lock the body or wheels to achieve the purpose of anti-theft.
[0003] The chain lock is light and easy to store. When not in use, it can be stored on the seat tube under the saddle. Therefore, it is favored by people. However, in the existing chain locks, during the user's subsequent riding after the chain lock is stored, due to the bumps on the road, the chain links in the chain of the chain lock collide with each other, making noise, reducing the quality of the user's riding, reducing the riding comfort, and causing problems such as the user's irritability due to the noise generated by the chain links during the riding process. Summary of the Utility Model

The head end or the tail end of the lock body part is detachably connected to the lock head part, and the other end of the lock body part is fixedly connected to the lock head part. The lock body part includes a chain assembly. The chain assembly includes an EVA foam tube and a chain arranged in the EVA foam tube. A steel wire for facilitating folding and storage and a buffer belt for reducing noise are wound around the chain.
[0006] Preferably, the lock head part includes a lock core and lock bow heads arranged on both sides of the lock core. The lock bow heads are detachably connected to the lock core. The first and last sections of the chain are respectively fixedly connected to the lock bow heads arranged on both sides of the lock core. The end of the chain and the end of the lock bow head far from the lock core are fixedly connected. The chain is detachably connected to the lock core through the lock bow head.
[0007] Preferably, a lock core sleeve is sleeved outside the lock core, and a lock head sleeve is sleeved outside the lock bow head.
[0008] Preferably, lock holes for cooperating with the lock bow heads to lock are arranged on both sides of the lock core.
[0009] Preferably, the chain is composed of a plurality of mutually sleeved chain links, and the steel wire and the buffer belt are evenly wound around each chain link.
[0010] Preferably, the buffer belt includes a luggage belt, a backpack strap, a binding rope, a rubber band or an elastic cord.
[0011] Preferably, an unlocking hole is provided on the lock core.
[0012] Compared with the prior art, the advantages of the present utility model are as follows: by winding the steel wire and the buffer belt between the chain links, the steel wire solves the problem that the chain is difficult to untangle due to entanglement, facilitating the folding and storage of the chain lock. The buffer belt prevents the chain links from colliding with each other due to bumps during the vehicle riding process, thereby reducing the noise generated during the vehicle riding process, improving the riding quality of the user, and enhancing the riding comfort.
