Description

Technical Field

[0001] The utility model relates to the technical field of bicycle locks, and more specifically, to a bicycle lock structure. Background Art

[0002] A bicycle lock is a common device used to lock a bicycle, which can effectively prevent the bicycle from being stolen when people park the bicycle outdoors.

[0003] When using a bicycle lock to lock the bicycle, the end of the chain needs to be inserted into the lock hole. In the existing bicycle locks, usually only when the end of the chain is inserted into the innermost part of the lock hole, the lock catch in the lock body can lock the end of the chain. However, when the end of the chain is inserted into the lock hole, it is difficult for the user to observe the position of the end of the chain. Therefore, it is easy for the user to be negligent and cause the end of the chain not to be inserted in place, resulting in the end of the chain inserted into the lock hole not being locked, and the safety is relatively poor. Summary of the Utility Model

[0004] The utility model provides a bicycle lock structure, which solves the technical problem that in the prior art, it is easy for the user to be negligent and cause the end of the chain not to be inserted in place, resulting in relatively poor safety.

[0005] In view of the above problems, the technical solution proposed by the utility model is as follows:

[0006] A bicycle lock structure includes a lock shell, a chain and a lock hole. A receiving cylinder is arranged at a position on one side of the lock shell opposite to the lock hole. The bicycle lock structure further includes a group of touch rods. A round hole communicating with the receiving cylinder is opened on one side of the lock shell. One end of the touch rod extends into the interior of the lock shell through the round hole and is aligned with the lock hole. The other end of the touch rod extends into the interior of the receiving cylinder through the round hole and is fixedly connected with a movable plate. A spring is further arranged in the receiving cylinder. One end of the spring abuts against the movable plate, and the other end of the spring abuts against the inner wall of the receiving cylinder. An indicating ring is connected to the outer side of the movable plate, and a transparent observation port is arranged on the surface of the receiving cylinder.

[0007] Further, a guiding column is fixedly arranged in the receiving cylinder. The indicating ring is nested on the surface of the guiding column. A notch is opened on the guiding column. A connecting bar is fixedly connected to the indicating ring. One end of the connecting bar passes through the notch and is connected to the movable plate.

[0008] Further, a fluorescent layer is arranged on the surface of the indicating ring.

[0009] Further, a storage bag is fixedly connected to the lock shell, and a zipper is arranged on the storage bag.

[0010] Furthermore, the lock housing is divided into a first assembled housing and a second assembled housing. The first assembled housing is provided with screw holes, and the second assembled housing is provided with fixing holes at positions corresponding to the screw holes.

[0011] Furthermore, the lock housing is made of metal.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the user inserts the chain into the inside of the lock hole to lock the vehicle, one end of the chain can push the movable plate inside the receiving cylinder to move. At this time, the indicating ring will move under the drive of the movable plate. When the chain is inserted to the innermost side of the lock hole, the indicating ring will just align with the transparent observation port on the receiving cylinder under the pushing action. Therefore, the user can judge whether the chain has been inserted to the innermost side of the lock hole by whether the indicating ring can be observed through the transparent observation port on the receiving cylinder, avoiding the situation that the end of the chain cannot be locked by the lock catch inside the lock housing due to the chain not being inserted in place, thereby improving the safety of the vehicle lock.

Detailed implementation manners

[0021] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6 , a bicycle lock structure, including a lock housing 1, a chain 2 and a keyhole 3. A receiving cylinder 4 is provided at a position on one side of the lock housing 1 opposite to the keyhole 3. The bicycle lock structure further includes a set of contact rods 5. A round hole 6 communicating with the receiving cylinder 4 is opened on one side of the lock housing 1. One end of the contact rod 5 extends into the interior of the lock housing 1 through the round hole 6 and is aligned with the keyhole 3. The other end of the contact rod 5 extends into the interior of the receiving cylinder 4 through the round hole 6 and is fixedly connected to a movable plate 7. A spring 8 is further provided in the interior of the receiving cylinder 4. One end of the spring 8 abuts against the movable plate 7, and the other end of the spring 8 abuts against the inner wall of the receiving cylinder 4. An indicating ring 9 is connected to the outer side of the movable plate 7. A transparent observation port 10 is provided on the surface of the receiving cylinder 4.

[0024] When the end of the chain 2 is inserted into the inside of the lock housing 1 through the keyhole 3, one side of the end of the chain 2 will come into contact with one end of the contact rod 5. At this time, the contact rod 5 will extend into the inside of the receiving cylinder 4 under the pushing action of the chain 2. One end of the contact rod 5 will drive the movable plate 7 fixedly connected thereto to move inside the receiving cylinder 4. Furthermore, the indicating ring 9 will move under the drive of the movable plate 7. When the chain 2 is inserted to the innermost side of the keyhole 3, the lock catch inside the lock housing 1 locks the end of the chain 2. At this time, the movable plate 7 inside the receiving cylinder 4 is pushed to a position aligned with the transparent observation port 10. The color of the indicating ring 9 is different from the color of the receiving cylinder 4. The user can see the indicating ring 9 inside the receiving cylinder 4 through the transparent observation port 10 at this time. When unlocking the lock catch inside the lock housing 1, the chain 2 can be pulled out of the outside of the keyhole 3. During this process, the contact rod 5 is no longer under the pushing action of the chain 2, and the movable plate 7 will move back to its original position under the elastic force of the spring 8. At this time, the indicating ring 9 will move back to its original position under the drive of the movable plate 7 and will no longer be aligned with the transparent observation port 10. The user cannot observe the indicating ring 9 inside the receiving cylinder 4 through the transparent observation port 10. In summary, when locking the vehicle, the user can judge whether the chain 2 has been inserted to the innermost side of the keyhole 3 by whether the indicating ring 9 can be observed through the transparent observation port 10 on the receiving cylinder 4, avoiding the situation that the end of the chain 2 cannot be locked by the lock catch inside the lock housing 1 because the chain 2 is not inserted in place, thereby improving the safety of the vehicle lock.

[0025] Further, please refer to Figures 1-6 , a guide post 11 is fixedly arranged inside the receiving cylinder 4. The indicating ring 9 is nested on the surface of the guide post 11. A notch 12 is formed on the guide post 11. A connecting bar 13 is fixedly connected to the indicating ring 9. One end of the connecting bar 13 passes through the notch 12 and is connected to the movable plate 7.

[0026] Since the indicating ring 9 is nested on the surface of the guide post 11, the indicating ring 9 will always move along the direction of the guide post 11 under the driving action of the movable plate 7 and will not flip inside the receiving cylinder 4, thereby ensuring the normal use of the user.

[0027] Further, please refer to Figures 1-6 , a fluorescent layer is provided on the surface of the indicating ring 9.

[0028] The fluorescent layer on the surface of the indicating ring 9 enables the indicating ring 9 to be observed by people even at night, thereby making use of the night environment.

[0029] Further, please refer to Figures 1-6 , a placement bag 14 is fixedly connected to the lock housing 1. A zipper 15 is provided on the placement bag 14.

[0030] When riding a bicycle, the key that matches the lock housing 1 can be placed and stored inside the storage bag 14, and the zipper 15 can seal the storage bag 14 to prevent the user from losing the key during the ride.

[0031] Furthermore, please refer to Figures 1-6 , the lock housing 1 is divided into two parts, a first assembled housing 16 and a second assembled housing 17. A screw hole 18 is provided on the first assembled housing 16, and a fixing hole 19 is provided at a position corresponding to the screw hole 18 on the second assembled housing 17.

[0032] The first assembled housing 16 and the second assembled housing 17 are snapped together to form the overall lock housing 1. At this time, the positions of the screw hole 18 and the fixing hole 19 will be aligned one by one. Passing a screw through the fixing hole 19 and screwing it into the screw hole 18 can fixedly connect the first assembled housing 16 and the second assembled housing 17 for normal use. Unscrewing the screw from the screw hole 18 and the fixing hole 19 can separate the first assembled housing 16 and the second assembled housing 17, so as to repair the lock catch inside the lock housing 1.

[0033] Furthermore, please refer to Figures 1-6 , the lock housing 1 is made of metal.

[0034] The lock housing 1 made of metal has high strength and good wear resistance, and has a relatively long service life.

[0035] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
