Description
Technical field
This utility model relates to a kind of bicycle, especially relates to a kind of locking system.
Background technology
Bicycle is the short distance traffic instrument of a kind of green, environmental protection, also it is general conventional fitness tool, but the lockset of bicycle does not the most all have good solution, it is generally adopted by chain lock, U-shape lock and cable-type padlock etc. at present, but these locksets are the most inconvenient to carry, the most easily destroyed by people and untie.And in the middle of reality, the antitheft requirement of bicycle is the highest.These problems seriously govern the vehicles of this environmental protection of bicycle usage amount in daily life.
Summary of the invention
The bicycle lock that this utility model mainly solves existing for prior art is inconvenient to carry, easily by technical problems such as people's destructions, it is provided that lockset is integrated on bicycle by one, is difficult to the bicycle shaft self-locking system destroyed by people.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals: a kind of bicycle shaft self-locking system, including wheel shaft, flower-drum, it is characterized in that described wheel shaft includes a lock chamber, lock intracavity is provided with lock body, the inner of lock body is connected with a screw mandrel, lock cavity wall corresponding to screw mandrel position is provided with an opening, described screw mandrel is provided with a nut adaptive therewith, nut is provided with left driving lever and right driving lever, the rightest driving lever is provided with a pin-and-hole, a removable pin it is provided with in pin-and-hole, removable pin is on a left side, between right driving lever, the shank of part is provided with spacing preiection, it is provided with compression spring between left end and the described left bar of removable pin, the inner chamber of the described flower-drum face corresponding with the right-hand member of described removable pin is provided with the lock groove suitable with described removable pin.Use bicycle of the present utility model, its car locking process is as follows: insert a key in lock body, key matches with lock core, is rotated by lock body, owing to lock body is connected with screw mandrel, therefore lock body drives screw mandrel to rotate, the nut that screw mandrel rotarily drives on screw mandrel moves right, and the left driving lever being arranged on nut moves right, and left driving lever drives removable pin to move right, if removable pin is just directed at lock groove, complete car locking action；If removable pin is not in alignment with lock groove, when left driving lever moves right, compression spring is compressed, removable pin top is to the inwall of flower-drum, rotating flower-drum until removable pin is directed at lock groove, compression spring is replied, and removable pin is pushed in lock groove, complete car locking, at this moment can also rotate flower-drum, because when there being people to promote bicycle in this case, flower-drum is natural with vehicle wheel rotation, when removable pin alignment lock groove, removable pin can enter in lock groove naturally.This locking mode so that be difficult to unlock in the case of not having key, unless destroyed wheel shaft, flower-drum.
Releasing process: insert a key in lock body, key matches with lock body, being rotated by lock body, owing to lock body is connected with screw mandrel, therefore lock body drives screw mandrel to rotate, the nut that screw mandrel rotarily drives on screw mandrel is moved to the left, the right driving lever being arranged on nut is moved to the left, and owing to removable pin is provided with spacing preiection, right driving lever drive activity is moved to the left, removable pin is removed from lock groove, completes to unlock.
Of the present utility model bringing provides the benefit that, solves the bicycle lock existing for prior art inconvenient to carry, easily by technical problems such as people's destructions, it is achieved that one is integrated on bicycle, is difficult to the bicycle shaft self-locking system destroyed by people.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model；
Accompanying drawing 2 is a kind of structural representation of wheel shaft of the present utility model.
Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment:
nullSuch as Fig. 1、Shown in Fig. 2，This utility model is a kind of bicycle shaft self-locking system，Including wheel shaft 1、Flower-drum 12，Described wheel shaft 1 includes a lock chamber，Lock intracavity is provided with lock body 2，The inner of lock body 2 is connected with a screw mandrel 3，Lock cavity wall corresponding to screw mandrel 3 position is provided with an opening 14，Described screw mandrel is provided with a nut 4 adaptive therewith，Nut 4 is provided with left driving lever 6 and right driving lever 7，The rightest driving lever 7 is provided with a pin-and-hole 11，A removable pin 9 it is provided with in pin-and-hole，Removable pin 9 is on a left side、Between right driving lever, the shank of part is provided with spacing preiection 10，It is provided with compression spring 8 between left end and the described left driving lever of removable pin，Described flower-drum 12 is provided with annular cavity 5，This annular cavity 5 face corresponding with the right-hand member of described removable pin 9 is provided with 4 lock grooves 13 suitable with described removable pin，On the sidewall of these 4 equally distributed annular cavities of lock groove.
When this utility model to be passed through carries out car locking, insert a key in lock body, key matches with lock core, is rotated by lock body, owing to lock body is connected with screw mandrel, therefore lock body drives screw mandrel to rotate, the nut that screw mandrel rotarily drives on screw mandrel moves right, and the left driving lever being arranged on nut moves right, and left driving lever drives removable pin to move right, if removable pin is just directed at lock groove, complete car locking action；If removable pin is not in alignment with lock groove, when left driving lever moves right, compression spring is compressed, removable pin top is to the inwall of flower-drum, rotating flower-drum until removable pin is directed at lock groove, compression spring is replied, and removable pin is pushed in lock groove, complete car locking, at this moment can also rotate flower-drum, because when there being people to promote bicycle in this case, flower-drum is natural with vehicle wheel rotation, when removable pin alignment lock groove, removable pin can enter in lock groove naturally.This locking mode so that be difficult to unlock in the case of not having key, unless destroyed wheel shaft, flower-drum.
When needing to unlock, inserting a key in lock body, key matches with lock body, is rotated by lock body, owing to lock body is connected with screw mandrel, therefore lock body drives screw mandrel to rotate, and the nut that screw mandrel rotarily drives on screw mandrel is moved to the left, and the right driving lever being arranged on nut is moved to the left, owing to removable pin is provided with spacing preiection, right driving lever drive activity is moved to the left, and is removed by removable pin from lock groove, completes to unlock.
