[0002] Bicycles are a common product used for sports, fitness, leisure, and entertainment.

[0003] However, after a bicycle is parked, it needs to be locked with a lock to prevent theft. In the field of bicycle anti-theft devices, the most common products include U-locks, chain locks, and rope locks. These products typically fix the bicycle frame or wheels to a fixed object to prevent theft; however, these traditional locks only provide primary protection. Once the lock body or rope is cut, the entire bicycle can be moved without additional obstruction, leading to its theft. Therefore, there is an urgent need to design head tube locks and bicycles equipped with such locks to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a head tube lock and a bicycle with the lock, in order to overcome the aforementioned shortcomings in the prior art.

[0013] Preferably, the length of the steel cable is approximately 1.5M.

[0014] By adopting the above-mentioned utility model, a steel cable of about 1.5M in length can be used to easily tie the vehicle to a nearby railing or small tree.

[0015] Preferably, the maximum adjustment angle of the head tube fixing member is 90°, and after the head tube fixing member is adjusted, the position of the lock body is located directly below the handlebar fixing fork.

[0016] By adopting the above-mentioned utility model, with a 90° angle adjustment, the position of the lock body insertion hole is exactly below the handlebar fixed front fork, which facilitates the connection between the lock pins at both ends and the T-shaped enlarged lock pin head.

[0017] Preferably, the handlebar fixed fork is movably connected to the vehicle body, and the connection end of the handlebar fixed fork and the vehicle body is provided with positioning holes, and the internal threads of the positioning holes are connected with fixing bolts.

[0018] By adopting the above-mentioned utility model, the position of the handlebar fork can be quickly fixed by using fixing bolts.

[0019] The bicycle includes the head tube lock, a fixed bracket is fixedly installed on the surface of the frame, and the handlebar fixed fork is fixedly connected to the frame through the fixed bracket.

[0020] By adopting the above-mentioned utility model, the fixed bracket is used to assist in the fixed connection between the lock body and the vehicle body, which facilitates subsequent locking operations.

[0021] The head tube lock and the bicycle equipped with the lock provided by this utility model have the following advantages: When locking the bicycle with this head tube lock, the T-shaped enlarged lock pins and lock pins at both ends of the steel cable are inserted into the matching lock body and handlebar fork. Only the angle of the bicycle's front end needs to be adjusted so that the T-shaped enlarged lock pins can contact the lock pins, thereby securing the bicycle. This ensures that even if the steel cable is damaged, the bicycle will still maintain a locked front end, reducing the chance of the bicycle being stolen and making it convenient to use.
