[0042] The terms “first”, “second”, etc., are used interchangeably to distinguish one feature from another and are not intended to indicate that each feature must be located in the position shown in the figure in each embodiment.
[0043] like Figures 1 to 6 As shown, the anti-theft bicycle light includes a lock body 1, which is equipped with a locking pin 2, which has a locked position and an unlocked position. Figures 1 to 3 In the embodiment shown, Figure 1 Lock pin 2 is in the locked position. Figure 3 Lock pin 2 is in the unlocked position. Figures 4 to 6 In the embodiment shown, Figure 4 Lock pin 2 is in the locked position. Figure 5 and Figure 6 Locking pin 2 is in the unlocked position. Locking pin 2 is locked by lock body 1 in the locked position. Lock body 1 can be unlocked to allow locking pin 2 to change from the locked position to the unlocked position. As described later, the change of locking pin 2 between the locked position and the unlocked position can be achieved by manipulating the movement of locking pin 2.
[0044] like Figures 1 to 6 As shown, the anti-theft bicycle light also includes a light 3, which is equipped with a light slot 4. The light slot 4 is located in the lock body 1. The light 3 is inserted into the light slot 4 and thus installed in the lock body 1. The light 3 is removed from the light slot 4 and thus removed from the lock body 1.
[0045] like Figures 1 to 6 As shown, the anti-theft bicycle light also includes a U-shaped latch 5, which is equipped with a threaded fastener 6. The U-shaped latch 5 is disposed on the lock body 1. Tightening the threaded fastener 6 onto the U-shaped latch 5 locks the bicycle, thereby installing the lock body 1 onto the bicycle. Loosening the threaded fastener 6 releases the U-shaped latch 5 from the bicycle, allowing the lock body 1 to be removed from the bicycle. In the illustrated embodiment, the U-shaped latch 5 may have a circular central hole 7. Tightening the threaded fastener 6 onto the U-shaped latch 5 locks the bicycle handlebar 8 within the circular central hole 7, thereby installing the lock body 1 onto the bicycle handlebar 8. Loosening the threaded fastener 6 releases the U-shaped latch 5 from the circular central hole 7 onto the bicycle handlebar 8, allowing the lock body 1 to be removed from the bicycle handlebar 8. In another embodiment, the U-shaped latch 5 can lock onto the bicycle frame, thereby installing the lock body 1 onto the bicycle.

[0046] like Figure 1 and Figure 4 As shown, the locking pin 2 is provided with a first blocking part 9. When the locking pin 2 is in the locked position, the first blocking part 9 prevents the lamp 3 from exiting the lamp slot 4, thus preventing the lamp 3 from being removed from the lock body 1. To remove the lamp 3 from the lock body 1, the lock body 1 must be unlocked and the locking pin 2 must be changed to the position shown. Figure 3 and Figure 5 The unlocked position shown allows the first blocking part 9 to no longer obstruct the lamp 3 from exiting the lamp slot 4, allowing the lamp 3 to exit the lamp slot 4 and thus be removed from the lock body 1. (See example...) Figure 1 and Figure 4 As shown, the locking pin 2 is also provided with a second blocking part 10. When the locking pin 2 is in the locked position, the second blocking part 10 also prevents the threaded fastener 6 from loosening the U-shaped lock buckle 5, thus preventing the lock body 1 from being removed from the bicycle. To remove the lock body 1 from the bicycle, the lock body 1 needs to be unlocked and the locking pin 2 changed to the position shown. Figure 3 and Figure 5 The unlocking position shown allows the second blocking part 10 to no longer block the threaded fastener 6 from loosening the U-shaped lock 5, and the threaded fastener 6 loosens the U-shaped lock 5, thereby removing the lock body 1 from the bicycle.
[0047] exist Figures 1 to 3 In the embodiment shown, the locking pin 2 can be inserted into the lock body 1 in the locked position, and the locking pin 2 can be pulled out of the lock body 1 to change to the unlocked position. When the locking pin 2 is pulled out of the lock body 1, it causes the first blocking part 9 to move in a straight line away from the blocking position, thereby allowing the lamp 3 to exit the lamp slot 4. When the locking pin 2 is pulled out of the lock body 1, it also causes the second blocking part 10 to move in a straight line away from the blocking position, thereby allowing the threaded fastener 6 to loosen the U-shaped lock buckle 5, thus realizing the change of the locking pin 2 from the locked position to the unlocked position.
[0048] exist Figures 4 to 6 In the embodiment shown, the locking pin 2 can rotate around the central axis to change from the locked position to the unlocked position. The rotation of the locking pin 2 causes the first blocking part 9 to rotate and shift away from the blocking position, thereby allowing the lamp 3 to exit the lamp slot 4. The rotation of the locking pin 2 also causes the second blocking part 10 to rotate and shift away from the blocking position, thereby allowing the threaded fastener 6 to loosen the U-shaped lock 5, thus realizing the change of the locking pin 2 from the locked position to the unlocked position.
[0049] like Figures 1 to 3 As shown, the locking pin 2 may include a tongue 11 and a crown 12, with the tongue 11 protruding from the crown 12. In the locked position, the tongue 11 is inserted into the lock body 1 and locked by the lock body 1, while the crown 12 is located outside the lock body 1 to facilitate the application of force to manipulate the locking pin 2 to the unlocked position. Figures 1 to 3 In the illustrated embodiment, after the lock body 1 is unlocked, force is applied to the crown 12 to pull the tongue 11 out of the lock body 1, causing the locking pin 2 to move to the unlocked position. Figures 4 to 6 In the illustrated embodiment, the locking pin 2 may also include a crown 12 and a tongue 11 protruding from the crown 12, but the tongue 11 is... Figures 4 to 6Not shown in the diagram. In the locked position, the tongue 11 is inserted into the lock body 1 and locked by the lock body 1, while the crown 12 is located outside the lock body 1 to facilitate the application of force to manipulate the locking pin 2 to the unlocked position. Figures 4 to 6 In the illustrated embodiment, after the lock body 1 is unlocked, force is applied to the crown 12 to cause the locking pin 2 to rotate around the tongue 11, thus changing the locking pin 2 to the unlocked position. In the illustrated embodiment, the lock body 1 can be a common combination lock, which includes multiple numeric dials, each with a recess, and the tongue 11 with multiple protruding teeth. The protruding teeth of the tongue 11 are engaged by the numeric dials, allowing the lock to be unlocked. Figures 1 to 3 In the illustrated embodiment, the tongue 11 cannot be pulled out, so that in Figures 4 to 6 In the illustrated embodiment, the tongue 11 cannot rotate, thus being locked by the lock body 1. Rotating the dials aligns the concave parts of each dial with the convex teeth of the tongue 11, thereby... Figures 1 to 3 In the illustrated embodiment, the tongue 11 is allowed to be pulled out from the lock body 1, such that... Figures 4 to 6 In the illustrated embodiment, the tongue 11 is allowed to rotate within the lock body 1 to unlock the lock body 1.
[0050] like Figure 1 and Figure 4 As shown, when the locking pin 2 is in the locked position, the first blocking part 9 can block the entrance 13 of the lamp slot 4 to prevent the lamp 3 from exiting the lamp slot 4. In the illustrated embodiment, the first blocking part 9 can block the insert 14 of the lamp 3 at the entrance 13 of the lamp slot 4, preventing the insert 14 from exiting the lamp slot 4 from the entrance 13, thereby preventing the lamp 3 from exiting the lamp slot 4.

In another embodiment, the first blocking part 9 may block the entrance 13 of the lamp slot 4, preventing the insert 14 from exiting the lamp slot 4 from the entrance 13, thereby preventing the lamp 3 from exiting the lamp slot 4.
[0051] like Figure 1 and Figure 4 As shown, when the locking pin 2 is in the locked position, the second blocking part 10 can block the head 15 of the threaded fastener 6, preventing the threaded fastener 6 from moving axially, thereby preventing the threaded fastener 6 from loosening the U-shaped lock 5. Furthermore, when the threaded fastener 6 tightens the U-shaped lock 5, the head 15 of the threaded fastener 6 can be inserted into the countersunk hole 16 of the U-shaped lock 5. When the locking pin 2 is in the locked position, the second blocking part 10 blocks the countersunk hole 16, so that the head 15 of the threaded fastener 6 inside the countersunk hole 16 cannot be touched, thereby preventing the threaded fastener 6 from loosening the U-shaped lock 5. Figure 6 The arrows in the diagram indicate the direction in which the threaded fastener 6 tightens the U-shaped latch 5, and the direction in which the threaded fastener 6 loosens the U-shaped latch 5 is the opposite of the direction indicated by the arrows.
[0052] like Figure 1 and Figure 4 As shown, the first blocking part 9 can be provided on the crown 12 and protrude from the crown 12. In the locked position, the first blocking part 9 protrudes to the entrance 13 of the lamp slot 4. The lamp 3 and the lamp slot 4 can be provided on the top of the lock body 1. The first blocking part 9 can protrude upward from the crown 12 to block the entrance 13 of the lamp slot 4.
[0053] like Figure 1 and Figure 4 As shown, the second blocking part 10 may be provided in the crown 12 and protrude from the crown 12. In the locked position, the second blocking part 10 protrudes to the head 15 of the threaded fastener 6. The U-shaped latch 5 and the threaded fastener 6 may be provided at the bottom of the lock body 1. The second blocking part 10 may protrude downward from the crown 12 to block the head 15 of the threaded fastener 6.
[0054] like Figure 1 and Figure 4 As shown, when the locking pin 2 is in the locked position, the crown 12 can be located at the rear longitudinal side of the lock body 1, and the inlet 13 of the lamp slot 4 can be located at the rear longitudinal side of the lamp slot 4, so that the inlet 13 of the lamp slot 4 is close to the crown 12 and can be easily blocked by the first blocking part 9 on the crown 12. The head 15 of the threaded fastener 6 can be located at the rear longitudinal side of the threaded fastener 6, so that the head 15 of the threaded fastener 6 is close to the crown 12 and can be easily blocked by the second blocking part 10 on the crown 12. Figures 1 to 3 In the illustrated embodiment, the longitudinal direction can be the extending direction of the tongue 11. Figures 4 to 6 In the illustrated embodiment, the longitudinal direction can be the extension direction of the central axis of rotation of the locking pin 2. The lamp groove 4 can also extend longitudinally.
