Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle anti-theft technology, specifically a bicycle anti-theft device. Background Technology
[0002] Moderate cycling is beneficial to health, but due to the light weight of bicycles, theft remains a serious problem. People usually lock their bicycles to railings or lampposts to improve their anti-theft capabilities. Existing shopping malls, parks, pedestrian streets, etc., rarely have anti-theft devices specifically for bicycles, which reduces the convenience for cyclists. Utility Model Content
[0003] The purpose of this invention is to provide a bicycle anti-theft device, which aims to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: the bicycle anti-theft device includes a support plate, and the support plate is provided with a plurality of anti-theft units: The anti-theft unit includes a base tube and a top rod. The lower end of the top rod has a groove. The base tube and the groove are respectively provided with fixing rods. It also includes a cylindrical spring. The two ends of the cylindrical spring are respectively located in the base tube and the groove. The two fixing rods are respectively located inside the two ends of the cylindrical spring. The outer surface of the push rod is provided with two retaining rings, and a collar is slidably connected to the push rod, with the collar located between the two retaining rings; A circular ring is rotatably connected to one side of the outer surface of the collar, and a spare lock is provided on the other side of the outer surface of the collar.
[0005] Preferably, the interval between two adjacent sets of anti-theft units is not less than 1 meter.
[0006] Preferably, one end of the fixing rod is provided with a stud, and both the support plate and the groove are provided with threaded holes that mate with the stud.
[0007] Preferably, both the fixing rod and the cylindrical spring are made of steel, and the two ends of the cylindrical spring are connected to the fixing rod by welding.
[0008] Preferably, the bottom cylinder and the support plate are connected by bolts, the lower end of the bolts penetrates the support plate, and the length of the lower end of the bolts extending beyond the support plate is approximately 2 to 3 times the thickness of the support plate. The system also includes several cement blocks buried in the ground, each cement block having a threaded tube inside, and the bolts are connected to the threaded tubes.
[0009] The beneficial effects of this utility model are: When using this anti-theft device, the rider can directly connect the bicycle to the ring via a lock. Since the support plate is directly installed on the ground, the bicycle's anti-theft capability is significantly improved after being connected to the ring. At the same time, because the ring can move up and down and can also rotate, and can also swing in a circular motion under the action of the cylindrical spring, it can ensure that most bicycles can be connected to the ring via a lock. In addition, a spare lock is provided for riders who do not have a lock or have lost their lock, greatly improving convenience. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0016] like Figure 1-4 As shown, a bicycle anti-theft device includes a support plate 1, on which a plurality of anti-theft units are provided: The anti-theft unit includes a base tube 2 and a top rod 3. The bottom end of the top rod 3 has a groove. The base tube 2 and the groove are respectively provided with fixing rods 4. It also includes a cylindrical spring 5. The two ends of the cylindrical spring 5 are located in the base tube 2 and the groove, respectively. The two fixing rods 4 are located inside the two ends of the cylindrical spring 5. Two retaining rings 6 are provided on the outer surface of the push rod 3, and a collar 7 is slidably connected to the push rod 3, with the collar 7 located between the two retaining rings 6; A ring 8 is rotatably connected to one side of the outer surface of the collar 7, and a spare lock 9 is provided on the other side of the outer surface of the collar 7.
[0017] The spare lock 9 can be a manual lock with a key or an intelligent electronic lock. When it is an intelligent electronic lock, a QR code 14 for unlocking can be affixed to the surface of the top rod 3. The electronic lock is normally in a locked state. After entering the mini-program through QR code 14 and binding the identity, it can be unlocked. The electronic lock can be locked manually. If it is not locked within a certain time, such as 3 minutes, it will lock automatically. When opening it again, it is also necessary to enter the mini-program through QR code 14 to unlock it.
[0018] When using this anti-theft device, the rider needs to park the bicycle 15 on one side of the anti-theft unit. If the rider has his own lock, he can connect the bicycle 15 to the ring 8 through the lock. Since the ring 8 can rotate on the collar 7 and the collar 7 can move back and forth between the upper and lower retaining rings 6 along the top rod 3, and since the cylindrical spring 5 is present, the top rod 3 can move forward, backward and left and right, thus ensuring that the bicycle 15 is connected to the ring 8 through the lock.
[0019] If the rider's bicycle 15 is not equipped with a lock, the spare lock 9 that comes with the anti-theft unit can be used to connect the bicycle 15 to the anti-theft unit.
[0020] Furthermore, the interval between two adjacent sets of anti-theft units shall not be less than 1 meter.
[0021] Ensure that there is sufficient space on both sides of the anti-theft unit to facilitate the connection between the bicycle 15 and the anti-theft unit, and that when the spare lock 9 or ring 8 in a single anti-theft unit is occupied, the unoccupied ring 8 or spare lock 9 in the anti-theft unit can also meet the connection requirements of the qualified bicycle 15 with the anti-theft unit.
[0022] Furthermore, a stud 10 is provided at one end of the fixing rod 4, and threaded holes that mate with the stud 10 are provided in both the support plate 1 and the groove. The fixing rod 4 is installed on the support plate 1 or the groove through the mating of the stud 10 and the threaded holes.
[0023] Furthermore, both the fixing rod 4 and the cylindrical spring 5 are made of steel, and the two ends of the cylindrical spring 5 are connected to the fixing rod 4 by welding.
[0024] Welding the cylindrical spring 5 to the fixed rod 4 together improves the connection stability between the two and enhances the overall stability.
[0025] Furthermore, the bottom cylinder 2 is connected to the support plate 1 by bolts 11. The lower end of the bolt 11 passes through the support plate 1, and the length of the lower end of the bolt 11 extending beyond the support plate 1 is about 2 to 3 times the thickness of the support plate 1. It also includes several cement blocks 12 buried under the ground 16. The cement blocks 12 are provided with threaded pipes 13 inside, and the bolts 11 are connected to the threaded pipes 13.
[0026] When bolt 11 is connected to threaded pipe 13, it can simultaneously fix support plate 1 and bottom cylinder 2.
[0027] This anti-theft device can be used in parks, shopping malls, pedestrian streets, and other places with staff to facilitate routine maintenance.
