In addition, the conventional bicycle locking means are mostly made of a chain or loop form to be locked with a lock, so they usually hang on a bicycle and used for unlocking the bicycle after storage. If lost, you can not use the lock means to discard or have to re-create the key in the key point there was a problem that costs a lot.

In addition, there is a safety problem that often causes theft accident, such as stealing the bicycle in the unlocked way by cutting the chain or ring portion of the locking means.

An object of the present invention is to provide a bicycle locking device using a number key to prevent the loss of the key is not necessary to carry the key by forming a lock function by fixing the number key to the handle so that the wheel does not rotate.

Another object of the present invention to provide a bicycle lock using a number key that can prevent theft of the bicycle due to the cutting of the locking device without using a chain or a hook.

Bicycle lock device using a number key of the present invention for achieving the above object, the number key lock body 10, the number key 12 formed on the front and back of the number key lock body 10, and the number A hook 14 installed below the front and rear number keys 12 of the key lock body 10 and fixed to the bicycle handle 20, and a hole 17 formed in the lower portion of the number key lock body 10; Locking support 16 is inserted between the nut 24 fastened to the rotation fixing shaft 22 of the front wheel of the bicycle and inserted into the hole 17 of the key lock body 10, and the locking support ( 16 is formed integrally with the locking fastening portion 15 having a fixing groove 19 to be fixed so as not to fall out of the number key lock body 10 when the number key 12 is locked by turning the number key 12, and It is installed at the lower part of the lock support 16 to fix the wheels of the bicycle front wheels It is characterized by consisting of a wheel rotation fixing portion 18 to prevent rotation.

The lower end portion of the locking support 16 is formed in a semi-circular shape is characterized in that it is formed so as not to fall in contact with the wheel rotation fixed shaft 22 when performing the bicycle locking function.

The present invention performs a locking function by fixing the wheel so that the wheel is not rotated by using the number key when storing the bicycle, and when using the bicycle, there is no need to carry the key by releasing the lock function by using the number key. There is no advantage, there is an advantage that can prevent theft of the bicycle due to the cutting of the locking device does not use a chain or hook.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings in which: FIG. It should be understood, however, that the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It should be noted that the embodiments of the present invention described below are only for explaining the spirit of the present invention to a person skilled in the art, and a detailed description of known functions and configurations of the present invention which may unnecessarily obscure the gist of the present invention It should be noted that it is omitted.

1 is a structural diagram of a locked state of a bicycle lock using a number key according to an embodiment of the present invention,

Figure 2 is a perspective view of the detached state of the bicycle lock using the number key according to an embodiment of the present invention.

The key lock body 10,

A number key 12 formed on an upper front and rear surface of the number key lock body 10,

A hook 14 installed below the front and rear number keys 12 of the number key lock main body 10 and fixed to the bicycle handle 20;

Hole 17 formed in the lower portion of the key lock body 10,

A locking support 16 fitted between the nuts 24 fastened to the rotation fixing shaft 22 of the front wheel of the bicycle and inserted into the hole 17 of the key lock body 10;

The lock fastening part 15 is formed integrally with the lock support 16 and has a fixing groove 19 for fixing the number key 12 so as not to fall out of the number key lock body 10 when the lock key is turned. )Wow,

Is installed in the lower portion of the lock support 16 is fixed to the wheels of the front wheel of the bicycle is composed of a wheel rotation fixing portion 18 to prevent the bicycle wheel is rotated.

The lower end portion of the locking support 16 is formed in a semi-circular shape is formed so as not to come off when performing the bicycle locking function in contact with the wheel rotation fixed shaft 22.

1 to 2 will be described in detail the operation of the bicycle lock device using the number key according to an embodiment of the present invention.

First, in order to unlock the bicycle lock device, if the password of the number key 12 is matched, the member inserted into the fixing groove 19 in the number key lock body 10 is opened so that the fixing groove 19 falls out. Can be. At this time, when the user lifts the number key lock main body 10 inserted into the bicycle handle 20, the lock support 16 is separated from the number key lock main body 10.

In such a separated state, turn the locking support 16 to the wheel rotation fixing part 18 in the opposite direction in which the wheels of the bicycle wheels are located, and then between the nuts 24 fastened to the rotation fixing shaft 22 of the front wheel of the bicycle. Insert in. Then, the hook 14 of the key lock body 10 is mounted to be hooked to the bicycle handle 20, and then the lock fastening portion 15 of the lock support 16 is inserted into the hole 17 and the number key ( If you turn 12), the number key lock is fixed to the bicycle so that it does not move and the user can use the bicycle.
