[0004] According to an embodiment of the present invention, the anti-theft bicycle light includes a lock body, a light, and a U-shaped lock. A lock pin is disposed on the lock body, and the lock pin has a locked position and an unlocked position. The lock pin is locked to the lock body at the locked position and is allowed to shift to the unlocked position when the lock body is unlocked. The light has a light slot disposed on the lock body and is attached to the lock body by being detachably inserted into and connected to the light slot. The U-shaped lock has a screw fastening component disposed on and installed on the lock body. The U-shaped lock is fastened to the bicycle by tightening the U-shaped lock with the screw fastening component, and the lock body is attached to the bicycle. Among them, the lock pin has a first blocking portion and a second blocking portion. When the lock pin is in the locked position, the first blocking portion prevents the light from coming out of the light slot, and the second blocking portion prevents the screw fastening component from loosening the U-shaped lock. When the lock pin shifts to the unlocked position, the first blocking portion releases the block and allows the light to come out of the light slot, and the second blocking portion releases the block and allows the screw fastening component to loosen the U-shaped lock.
[0005] In one or more embodiments, the lock pin is inserted into the lock body at the locked position and shifts to the unlocked position by being pulled out of the lock body.
[0006] In one or more embodiments, the lock pin shifts from the locked position to the unlocked position by rotating around a central axis.
[0007] In one or more embodiments, the lock pin includes a tongue portion and a crown portion. The tongue portion protrudes and extends from the crown portion. At the locked position, the tongue portion is inserted into the lock body, and the crown portion is located outside the lock body to be operated at the unlocked position.
[0008] In one or more embodiments, the lock pin, when in the locked position, causes the first blocking portion to block the entrance of the light slot, thereby preventing the detachment of the light.
[0009] In one or more embodiments, the lock pin, when in the locked position, causes the second blocking portion to receive the head of the screw fastening component, thereby preventing the loosening of the screw fastening component.
[0010] In one or more embodiments, the head of the screw fastening component is immersed in the counterbore of the U-shaped lock, and when the lock pin is in the locked position, the second blocking portion blocks the counterbore, thereby preventing the loosening of the screw fastening component.
[0011] In one or more embodiments, at the locked position, the first blocking portion projects and extends from the crown portion to the entrance of the light slot, thereby preventing the detachment of the light.
[0012] In one or more embodiments, at the locked position, the second blocking portion projects and extends from the crown portion to the head of the screw fastening component, thereby preventing the loosening of the screw fastening component.
[0013] In one or more embodiments, the U-shaped lock is provided with a circular central hole so as to be fastened to a bicycle handle.
[0014] The embodiments of the present invention have at least one of the following beneficial effects. The lock pin is provided with a first blocking portion. When the lock pin is in the locked position, the first blocking portion prevents the light from exiting the light slot, thereby preventing the light from being removed from the lock body. To remove the light from the lock body, it is necessary to unlock the lock body and move the lock pin to the unlocked position. As a result, the first blocking portion no longer prevents the light from detaching from the light slot, and the light can be removed from the lock body by exiting the light slot. The lock pin is further provided with a second blocking portion. When the lock pin is in the locked position, the second blocking portion prevents the screw fastening component from loosening the U-shaped lock, thereby also preventing the lock body from being removed from the bicycle. To remove the lock body from the bicycle, it is necessary to unlock the lock body and move the lock pin to the unlocked position. As a result, the second blocking portion no longer prevents the screw fastening component from loosening the U-shaped lock, and the lock body can be removed from the bicycle by the screw fastening component loosening the U-shaped lock.

Further, the second blocking portion 10 also linearly moves away from the blocking position, allowing the loosening of the U-shaped lock 5 by the screw fastening component 6. Thereby, the shift of the lock pin 2 from the locked position to the unlocked position is realized.
[0025] In the embodiment shown in FIGS. 4 to 6, the lock pin 2 can shift from the locked position to the unlocked position by rotating around the central axis. In conjunction with the rotation of the lock pin 2, the first blocking portion 9 rotates away from the blocking position, allowing the light 3 to exit from the light slot 4. Further, the second blocking portion 10 also rotates away from the blocking position, allowing the U-shaped lock 5 to be loosened by the screw fastening component 6. Thereby, the shift of the lock pin 2 from the locked position to the unlocked position is realized.
[0026] As shown in FIGS. 1 to 3, the lock pin 2 can include a crown portion 12 and a tongue portion 11 extending protruding from the crown portion 12. In the locked position, the tongue portion 11 is inserted into the lock body 1 and locked to the lock body 1, and the crown portion 12 is outside the lock body 1, and by being biased, it facilitates operating the lock pin 2 to shift to the unlocked position. In the embodiment shown in FIGS. 1 to 3, after the lock body 1 is unlocked, the crown portion 12 is biased to pull the tongue portion 11 out of the lock body 1 and shift the lock pin 2 to the unlocked position. In the embodiment shown in FIGS. 4 to 6, the lock pin 2 can similarly include a crown portion 12 and a tongue portion 11 extending protruding from the crown portion 12, but the tongue portion 11 is not shown in FIGS. 4 to 6. In the locked position, the tongue portion 11 is inserted into the lock body 1 and locked to the lock body 1, and the crown portion 12 is outside the lock body 1, and by being biased, it facilitates operating the lock pin 2 to shift to the unlocked position. In the embodiment shown in FIGS. 4 to 6, after the lock body 1 is unlocked, the crown portion 12 is biased to rotate the lock pin 2 around the tongue portion 11 and shift the lock pin 2 to the unlocked position. In the illustrated embodiment, the lock body 1 may be a normal dial-type lock, the lock body 1 includes a plurality of dials, each dial is provided with one recess, and the tongue portion 11 is provided with a plurality of protruding teeth. By the protruding teeth of the tongue portion 11 being caught by the dial, the tongue portion 11 in the embodiment shown in FIGS. 1 to 3 is prevented from coming out, and the tongue portion 11 in the embodiment shown in FIGS. 4 to 6 is prevented from rotating, and the tongue portion 11 is locked by the lock body 1.
