[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-3 A saddle tube battery anti-theft lock includes a lock cylinder body 1 and a lock cylinder body mounting base 2. The lock cylinder body 1 consists of a lock cover 4, a lock cylinder shell 8, and bolts 11, 12, 13, and a bolt 5 housed within the lock cylinder shell 8. The length of the lock cylinder body mounting base 2 is less than the length of the lock cylinder shell 8. Bolt 11 is connected to one end of bolt 212, and the other end of bolt 212 is connected to bolt 313. Bolt 313 has a pressure head 14 at the opposite end of bolt 212. The bolt 5 consists of a baffle 15, a bolt protrusion 16, and a spring 17. One end of the spring 17 is fixedly connected to a spring fixing base 18 on the wall of the lock cylinder shell 8, and the other end of the spring 17 is fixedly connected to the bolt protrusion 16. The baffle 15 is movably connected to the pressure head 14. A bolt protrusion extension groove is opened on the outer wall of the opposite end of the lock cylinder shell 8.
[0029] The lock cylinder body mounting base 2 consists of a lock cylinder body mounting cavity 6 and a lock cylinder body mounting edge 9, the latter being square in shape. The lock cylinder body mounting cavity 6 has a lock cylinder body fixing mounting hole 7 on its flat wall, and the shape of the lock cylinder body mounting cavity 6 matches that of the lock cylinder outer shell 8. A lock cover mounting hole is opened inside the lock cylinder body mounting edge 9, and the shape of the lock cover mounting hole is the same as that of the lock cover 4.
[0030] A lock cylinder mounting base 2 is provided on the outer wall of the lock cylinder mounting cavity 6, which is adjacent to the plane wall of the lock cylinder mounting base 2. A lock cylinder mounting base boss 10 is provided on the outer wall of the lock cylinder mounting cavity 6. A lock cylinder mounting hole 7 passes through the lock cylinder mounting base boss 10 and the lock cylinder mounting cavity 6.
[0031] Please see Figure 4-7 In this design, the saddle tube battery anti-theft lock is installed inside the lock cylinder body mounting shell 22. The lock cylinder body mounting shell 22 is fixedly connected to the saddle tube battery mounting tube 21. A latch protrusion telescopic hole 20 is provided on the outer wall of the saddle tube battery mounting tube 21.
