Description

A kind of multifunctional lock

The utility model relates to a kind of lock with multiple function, especially relates to a kind of lock that is used on bicycle, the tricycle.

Now, the lock kind that is used for bicycle, 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.

The purpose of this utility model provides a kind of lock with multiple function, and the single door bolt direction lock especially for bicycle, tricycle can be installed on the direction frame, conveniently, pin front fork securely, wheel is fixed on a certain direction, and to prevent stealing, and this lock can be changed lock core.

For achieving the above object, lock of the present utility model mainly is made of lock tube, lock pipe, lock bolt and lock core, lock core is installed in the lock tube separably, the lock tube bottom surface is connected with the lock pipe, corresponding with lock pipe position, correspondence position at lock tube and lock core has lockhole, the groove fit of the dead bolt of lock core on lockhole place and lock bolt.During use lock tube one side is fixed on the locked thing (as a side of the direction frame of bicycle, tricycle near the front fork place), lock core is put into lock tube, makes the lockhole alignment of lock core and lock tube.When locking straight type lock bolt is inserted lockhole, make the groove fit of the dead bolt and the lock bolt of lock core, then lock bolt plays the effect (blocking front fork rotates) of the locked thing motion of restriction.When unblanking, key is inserted in the lock core, rotating lock tongue separates dead bolt and groove on the lock bolt, upwards pulls out lock bolt this moment, can cooperate with dead bolt up to the lower recess of lock bolt, thereby lock bolt is blocked (front fork is free to rotate).

Lock of the present utility model also can have a coupling lock pipe that separates, 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.

Lock of the present utility model also can have a chain or steel cable, and an end links to each other with the top of lock bolt, and the other end links to each other with lock tube, utilizes chain or steel cable to pin object.

The utility model compared with prior art has rational in infrastructurely, unblanks conveniently the characteristics of good anti-theft effect, and lock core is what to separate with lock tube, can change lock core as required, and is easy to use, safety is better, and lock core can adopt different material manufacturings with lock tube, to reduce production costs.

With embodiment the utility model is elaborated with reference to the accompanying drawings below.

Fig. 1 is the decomposing schematic representation of an embodiment of the present utility model;

Fig. 2 is the front elevation drawing of this embodiment;

Fig. 3 is the part sectioned view along the line A-A among Fig. 2.

With reference to Fig. 1,2, shown in 3, lock of the present utility model is mainly by lock tube 1, lock pipe 2, lock bolt 3 and lock core 6 constitute, lock core 6 is installed in the lock tube 1 separably, lock core 6 is a square structure with lock tube 1, lock tube 1 bottom surface is welded with lock pipe 2, corresponding with the position of lock pipe 2, correspondence position at lock tube 1 and lock core 6 has lockhole, the groove fit of the dead bolt 5 of lock core 6 on lockhole place and lock bolt 3, there is an enlarged portion on lock bolt 3 tops, two place's grooves are arranged on the breechblock, prevent that lock bolt 3 from sliding, cooperate with dead bolt 5 when the upper grooves of lock bolt 3 is used for locking states, after lower recess is used for unblanking lock bolt 3 is fixed on lock and manages 2, prevent that lock bolt 3 from losing, keyhole 4 is positioned at a side at lock core 6 centers.

Side with lock tube 1 during use is fixed on direction frame one side of bicycle, tricycle near the front fork place, opening outwardly, lock core 6 is put into lock tube 1, make the lockhole alignment of the lockhole and the lock tube 1 of lock core 6, when locking straight type lock bolt 3 is inserted lockhole, the dead bolt 5 of lock core is cooperated with the upper grooves of lock bolt 3, thereby the front fork rotation is blocked in lock bolt 3 lower ends.When unblanking, key is inserted in the keyhole 4 of lock core 6, rotating lock tongue 5 separates dead bolt 5 and groove on the lock bolt 3, upwards pulls out lock bolt 3 this moment, can cooperate with dead bolt 4 up to the lower recess of lock bolt 3, thereby lock bolt 3 be blocked again, and makes front fork free to rotate

In this embodiment, lock tube can be fixed on the direction frame by the mode of welding or other bolt.Lock tube adopts steel preferably, and the material of lock core can adopt plain cast iron, has on the one hand lock tube that protection to lock core is provided, and avoids lock core destroyed, on the other hand, has reduced cost of production.Simultaneously,, can change lock core as required,,, or old lock core is replaced by new lock core with the raising safety as two lock cores are exchanged because lock core separates with lock tube.

Lock of the present utility model not only can be used on bicycle, the tricycle, also can provide one to hold the coupling lock pipe of lock bolt lower end, so just can above-mentioned lock and coupling lock pipe is fixing respectively, make lock bolt can be inserted in the coupling pipe, thereby the relative fixed of utilizing lock bolt and coupling to lock pipe limit the motion of locked thing.For example, lock tube can be fixed on the door, coupling lock pipe is fixed on relative doorframe or other Yishanmen, thereby by lock bolt door lock is lived.

Lock of the present utility model also can have chain or steel cable, and play and chain lock or the same effect of steel rope lock this moment, but reduced the too much action of tidying up.

What lock core and lock tube adopted in the present embodiment is square structure, also can adopt other shape certainly, and the shape of lock core, lock tube and lock pipe can be different, as long as both are cooperated.Certainly, keyhole also can be positioned at the arbitrary 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.
