Bicycles are a means of transportation used by many people, from children to the elderly. In recent years, bicycles have been set up because of the advantages of being able to achieve both the purpose of preventing pollution and improving health. The use of the bicycle is encouraged by installing a cradle for storing bicycles on the back.

The bicycle must be equipped with a separate locking device because it does not need a separate operation key for activating the engine for driving. As a result, a conventional chain lock is used to lock the wheels of the bicycle to the body frame. However, because the chain lock is easily cut by the cutter and the bike itself is light, it can be easily carried, so if you lift the bicycle first, then move it to another place and then cut the chain with a high-performance cutter, you can use or resell the bicycle without compromising performance. There was a problem that was vulnerable to theft.

In order to solve this problem, as disclosed in Korean Patent Registration No. 10-0959122, the steering shaft locking device is mounted in the frame so that it does not protrude on the exterior, thereby making the aesthetics beautiful, and in order to release the locking device after theft, A steering shaft locking device of a bicycle, which has been damaged due to a steering shaft damage, has been proposed.

However, the steering shaft locking device of the bicycle has the advantage of reducing the willingness to theft by connecting the steering shaft and the frame to damage the bicycle when unlocking the locking device. In case of failure of the manufacturing process such as design and manufacture, the cost of maintenance is greatly increased, such as the need to replace the frame itself, which makes it difficult to easily apply to a general bicycle.

The present invention has a lock rod that is inserted into or withdrawn from the insertion hole formed in the overlapping area in which the steering wheel steering shaft and the body frame of the bicycle are interconnected to secure the lock to the body frame can be fixed to prevent the handle from rotating By doing so, the object of the present invention is to provide a bicycle locker that can be easily applied without changing the manufacturing process of the existing bicycle, without being able to remove the lock without accompanying the body frame and steering shaft of the bicycle.

Hereinafter, the present invention will be described.

With regard to the task solution,
