Description

A kind of tricycle special-purpose theft-proof lock
Technical field
The utility model relates to a kind of theftproof lock that is exclusively used on the tricycle.
Background technology
Now, the kind that is used for the lock on the tricycle is a lot, also each is variant for its structure, what generally adopt all is directly to fasten mortise lock with a bolt or latch, two kinds of single door bolt and pair door bolts is arranged, when this lock is installed on the front fork, it is not too convenient to install, especially also have shock mitigation system etc. on the front fork of tricycle, and will bend over just can open when opening lock, use also inconvenient.Now also useful chain lock or steel rope lock, this lock will pierce into wheel or vehicle frame with chain or steel cable, and then pinning, and after opening lock, also lock will be tidied away, like this will the duplication of labour, use very inconvenient, time-consuming again.
In patent CN99255963.4, disclose a kind of lock, can be installed on the direction frame, made things convenient for, pin front fork securely, wheel has been fixed on a certain direction with multiple function.The shortcoming of this lock is must remove to pull out lock bolt with hand when unblanking, and the lower recess of lock bolt is cooperated with dead bolt, and lock bolt is blocked, and is very inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of list door bolt direction lock that is used for tricycle, can be installed on the direction frame, lock past front fork conveniently, securely, and wheel is fixed on a certain direction, and handled easily reduces and works simultaneously.
Lock of the present utility model comprises lock tube, the lock pipe, lock bolt, lock core, spring, lock core pilferproof closure and lock pipe lid, lock core is installed in the lock tube, the outer end is sealed with the lock core pilferproof closure, and expose keyhole, the lock tube bottom surface is connected with the lock pipe, corresponding with the position of lock pipe, correspondence position at lock tube and lock core has lockhole, the dead bolt of lock core at the lockhole place can with the groove fit on the lock bolt, described groove comprises be used for the upper grooves that cooperates with dead bolt when locking states, with be used for unblanking after lock bolt is fixed on the lower recess of lock pipe, a convex shoulder is arranged below the lower recess of lock bolt, below convex shoulder, be with spring on the lock bolt, this convex shoulder prevents bullet on the spring, in lock pipe bottom one lock pipe lid is arranged, the lock pipe is stamped the intermediate throughholes that lock bolt is passed through, and the spring that restriction is enclosed within on the lock bolt moves down.
Lock of the present utility model also has a corresponding coupling lock pipe that separates with lock tube, the lower end that holds lock bolt.
The beneficial effect of lock of the present utility model is owing to there is spring, has removed the operation of using the hand-lifting lock bolt when unblanking from, even not locking of lock bolt when vertical the installation, lock bolt can not glide yet, because spring has withstood.
Description of drawings
Fig. 1 is the decomposing schematic representation of an embodiment of the present utility model;
Fig. 2 is the part sectioned view of this embodiment;
Fig. 3 is the part sectioned view along the line A-A among Fig. 2.
The specific embodiment
With reference to Fig. 1,2, shown in 3, lock of the present utility model comprises lock tube 1, lock pipe 2, lock bolt 3, lock core 5, spring 8, lock core pilferproof closure 9 and lock pipe cover 10, lock core 5 is installed in the lock tube 1, the outer end is sealed with lock core pilferproof closure 9, and expose keyhole 4, lock tube 1 bottom surface is connected with lock pipe 2, corresponding with the position of lock pipe 2, correspondence position at lock tube 1 and lock core 4 has lockhole, the dead bolt 6 of lock core 5 at the lockhole place can with the groove fit on the lock bolt 3, lock bolt 3 the first half have two place's grooves, the upper grooves of lock bolt 3 is used for cooperating with dead bolt 6 when locking states, after lower recess is used for unblanking lock bolt 3 is fixed on lock pipe 2, prevents that lock bolt 3 from losing.One convex shoulder 7 is arranged below the low groove of lock bolt 3, be with spring 8 below 7 from convex shoulder on the lock bolt, convex shoulder 7 is used to prevent bullet on the spring 8, has a lock pipe to cover 10 in lock pipe 2 bottoms, intermediate throughholes can make lock bolt 3 freely pass through, but the spring 8 that restriction is enclosed within on the lock bolt moves down.
During use the mounting bar 11 of lock tube 1 one sides or lock pipe 2 one sides is fixed on the locked thing (as a side of the direction frame of bicycle, tricycle near the front fork place), keyhole 4 outwardly.When locking straight shape lock bolt is pressed, compression spring 8 makes the dead bolt 6 of lock core 5 and the groove fit of lock bolt 3, and then lock bolt 3 plays the effect (blocking front fork rotates) of the locked thing motion of restriction.When unblanking, key is inserted in the keyhole 4, rotating lock tongue 6 separates dead bolt 6 and groove on the lock bolt 3, and this moment, the spring jack-up lock bolt 3 that makes progress lifted restrictions, and makes locked thing can move (free to rotate as front fork).Because the operation with the hand-lifting lock bolt has been removed in the existence of spring from, does not lock lock bolt when vertically installing, lock bolt can not glide yet, because spring has withstood.
In this embodiment, mounting bar can be fixed on the direction frame of tricycle by the mode of welding or other bolt.Lock of the present utility model also can have segregative coupling lock pipe, and lock tube is separately fixed at different positions with coupling lock pipe, makes the lower end of lock bolt can be inserted in the coupling lock pipe, thereby utilizes the motion of lock bolt and the locked thing of coupling lock pipe restriction.
What lock core and lock tube adopted in the present embodiment is square structure, also can adopt other shapes certainly, and the shape of lock core, lock tube and lock pipe can be different, as long as both are cooperated, certainly, keyhole can be positioned at the arbitrarily suitable position of lock core.According to actual needs, the lock pipe of lock of the present utility model and the vary in size of lock tube are long or short, either large or small.The internal structure of lock core of the present utility model is common lock core structure, as long as can block the groove of lock bolt, can both realize the purpose of this utility model.Lock of the present utility model not only can be used for also can be used for door, vehicle steering etc. on bicycle, the tricycle.
