The main lock body 21 is provided with a lock head hole 211, a lock connection hole 212 and a lock tongue cavity 213. The lock head hole 211 is used to accommodate the lock head 23. A countersunk hole is provided at the proximal end of the lock head hole 211 so that the lock head 23 is fixed in the countersunk hole when it is recovered into the lock head hole 211. A lock tongue 214 is provided in the lock tongue cavity 213, and the lock tongue 214 is driven by a mechanical lock or an electromagnetic lock. In this embodiment, the lock tongue 214 is a mechanical lock and is driven by a key.

[0028] In this embodiment, a seat tube mounting base 121 is provided at one end of the mounting plate 12. Figure 3 and Figure 4 The seat tube mounting seat 121 is provided with a seat tube insertion hole 1211, a screw mounting hole 1215, a sinking groove, a tightening block hole 1216 and a locking assembly. The seat tube insertion hole 1211 corresponds to the seat tube hole 112 on the outer tube body 11. The sinking groove is provided on the outer surface of the seat tube mounting seat 121. The tightening block hole 1216 is provided on the inner wall of the seat tube insertion hole 1211. The screw mounting hole 1215, the sinking groove, the tightening block hole 1216 and the seat tube insertion hole 1211 are connected. The sinking groove and the tightening block hole 1216 are respectively provided on both sides of the screw mounting hole 1215. Specifically, the sinking groove is provided on the outer surface of the screw mounting hole 1215. On the other hand, the clamping block hole 1216 is located inside the screw mounting hole 1215. The locking assembly includes a jacking screw 1212, a spacer 1213, and a clamping block 1214. The spacer 1214 has a screw through hole. The spacer 1213 is located in the recess. The jacking screw 1212 passes through the screw through hole and the screw mounting hole 1215 of the spacer 1214 and is threadedly connected to the clamping block 1214 located in the clamping block hole 1216. By adjusting the jacking screw 1212 and the clamping block 1214 and utilizing the elasticity of the spacer 1214, the clamping block 1214 secures the seat tube 50 to the seat tube receptacle 1211. This is one method of securing the seat tube 50. In other embodiments, other securing structures for the seat tube 50 may also be used.

[0029] The drive motor 31 and the take-up reel 32 are disposed on the inner side of the seat tube mounting base 121. The drive motor 31 is used to drive the take-up reel 32 to rotate. In this embodiment, the drive motor 31 and the take-up reel 32 are fixed to the mounting plate 12. In other embodiments, the drive motor 31 and the take-up reel 32 may be fixed to the side wall of the seat tube mounting base 121. By fixing the drive motor and the take-up reel 32 to the mounting plate 12 and then fixing or welding the mounting plate 12 to the outer tube body 11, the convenience of installing the drive motor and the take-up reel 32 is improved.

[0030] The main lock body 21 is disposed outside the seat tube mounting base 121 and within the outer tube body 11. The outer tube body 11 protects the main lock body 21. The lock head hole 211 on the main lock body 21 is exposed to the outside, facilitating the removal of the lock head 23 in the lock head hole 211. A pull tab 24 is provided at one end of the lock head 23. The pull tab 24 includes a sleeve portion 241 and a sealing cover 242. The sleeve portion 241 is sleeved onto one end of the lock head 23.

The lock rope 22 is released or recovered by the forward and reverse rotation of the take-up wheel 32. When the lock rope 22 is released, the lock head 23 is pulled out by the pull buckle 24. The lock head 23 passes the lock rope 22 around the locking object and is inserted into the lock head hole 211. The lock head 23 is locked by the lock tongue 214 to lock the main beam tube and the locking object. The lock tongue 214 is opened, and the drive motor 31 is used to drive the take-up wheel 32 to recover the lock rope 22. The lock head 23 retracts into the lock head hole 211, so that the lock rope 22 and the lock head 23 are hidden, not easy to be damaged, and have good practicality.

[0032] In the above embodiment, the drive motor 31 and the take-up wheel 32 are arranged on one side of the seat tube mounting base 121, that is, one end of the body 10, and the fixed pulley 42 is arranged at the other end of the body 10. The positions of the drive motor 31, the take-up wheel 32 and the fixed pulley 42 do not affect the operation of the main beam tube with a built-in lock. In other embodiments, the drive motor 31 and the take-up wheel 32 can be arranged on a fixed base at the other end of the body 10, and the fixed pulley 42 is arranged at the end of the seat tube mounting base 121 of the body 10, and the lock rope 22 is guided through the fixed pulley 42.

A countersunk hole is provided at the proximal end of the lock head hole 211 so that the lock head 23 is fixed in the countersunk hole when it is recovered into the lock head hole 211. A lock tongue 214 is provided in the lock tongue cavity 213.

[0037] This embodiment differs from the first embodiment in that a seat tube mounting base 121 is provided at one end of the mounting plate 12. The main lock body 21 is located outside the seat tube mounting base 121 and within the outer tube 11. The outer tube 11 protects the main lock body 21. The locking head hole 211 on the main lock body 21 is exposed to the outside, facilitating the removal of the locking head 23 from the locking head hole 211. A pull tab 24 is provided at one end of the locking head 23. The pull tab 24 includes a sleeve portion 241 and a sealing cover 242. The sleeve portion 241 is sleeved onto one end of the locking head 23. The lock head 23 is pulled out using the pull tab 24. The sealing cover 242 engages with the main lock body 21, covering the locking head hole 211 and the locking connection hole 212, preventing them from being exposed. A fixed pulley 42 is provided on the inside of the seat tube mounting base 121. The other end of the mounting plate 12 is provided with a fixing seat 122, and the drive motor 31 and the take-up wheel 32 are provided on the fixing seat 122. The mounting plate 12 is also provided with a wire clamping plate 33 and a movable pulley 41.

The mounting plate 12 is provided with a slide rail 123. The movable pulley 41 is slidably provided on the slide rail 123 of the mounting plate 12 through a support leg. A pulling rope 34 is wound around the take-up wheel 32, and one end of the pulling rope 34 is fixed to the movable pulley 41 through the threading hole on the wire clamping plate 33. The take-up wheel 32 pulls or releases the movable pulley 32 through the pulling rope 34.

[0038] One end of the lock rope 22 is fixed to the lock head 23 , and the other end is wound around the fixed pulley 42 and the movable pulley 32 . Depending on the length requirement of the lock rope 22 , the other end of the lock rope 22 is fixed to the fixed pulley 42 or the movable pulley 32 .

[0039] The traction rope 34 is recovered by the pulley 32, and the lock head 23 is retracted into the lock head hole 211, so that the lock rope 22 and the lock head 23 are hidden, not easily damaged, and have good practicality.

[0040] In the above embodiment, the drive motor 31 and the take-up wheel 32 are arranged on one side of the fixed seat 122, that is, one end of the body 10, and the fixed pulley 42 is arranged at the other end of the body 10. The positions of the drive motor 31 and the take-up wheel 32 and the fixed pulley 42 do not affect the operation of the main beam tube with a built-in lock. In other embodiments, the drive motor 31 and the take-up wheel 32 can be arranged on the inner side of the seat tube mounting seat at the other end of the body 10, the fixed pulley 42 is arranged on the fixed seat 122 of the body 10, and the movable pulley 32 is slidably arranged on the mounting plate 12, which can still achieve the concealment of the lock rope 22 and the lock head 23.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
