This spiral locking -type locomotive subassembly has solved the vexation that the bicycle lock car need carry the lock in addition.
Description
Technical field
The utility model relates to bicycle assembly, and it is a kind of spiral locking-type headstock assembly.
Background technology
Bicycle, also known as bicycle or bicycle, the normally two small-sized land-going machines of taking turns.After people rides car, being power with foot pedal, is the vehicle of environmental protection.
General bicycle or folding bicycle often comprise headstock assembly, front component, wheel assembly, saddle assembly and common vehicle frame or folding stand, front component is connected with headstock assembly, by the front-drive in headstock assembly drive front component to regulate direction.
Bicycle is after finishing using, and need to find one interim to park a little, lock onto on the fence of parking, therefore user needs to carry the lockset such as anti-theft column lock, chain in addition, increases the worry that user carries.
At present, application number is that the Chinese patent of CN200810029367.0 discloses a kind of bicycle headstock handle with anti-theft locking function, specifically this headstock handle can be movable, can take off from headstock, so be just used as the handrail use of headstock in by bike, just take off when parking car and be used as anti-theft column lock to use.Such object be make antitheft and controlling party to function combine, go to pot to anti-theft feature, handrail controlling party to function also will go to pot, so just can avoid suffering physical disturbance as other anti-theft column locks by actv..
But this headstock is taken off as anti-theft column lock use due to needs, be vulnerable to pedestrian and ride or the rolling of other vehicles, cause headstock to damage; Headstock takes off frequently and installs, and easily cause headstock to connect not tight, generation is delivered to, and causes danger to driving.
Further, this this head uses comparatively inconvenient, needs headstock to take off and just can carry out anti-theft locking, if can directly by headstock by bicycle lock in sides such as fence, then can direct convenience a lot.
Utility model content
Goal of the invention of the present utility model is the worry needing to carry in addition lock in order to solve driving car locking, provides a kind of spiral locking-type headstock assembly.
In order to realize foregoing invention object, the utility model have employed following technical scheme: a kind of spiral locking-type headstock assembly, comprise annular handrail, handrail comprises the front end handle of direct rod shape, front end handle is provided with opening, the front end handle of opening part is provided with to fasten and makes handrail be closed locking sleeve, front end handle is provided with outside thread, locking sleeve inwall is provided with the negative thread matched with outside thread, locking sleeve is connected with front end handle bar spiral is flexible, the latch-up structure of restricted locking sleeve movement on the handle of described front end.
Further, described latch-up structure and locking sleeve are all positioned on the front end handle of opening the same side, and latch-up structure comprises dead bolt and opens the lock core of dead bolt locking.
Further, it is inner that described lock core and dead bolt are relatively arranged on front end handle, and lock core and dead bolt are positioned at the front end handle midway location of opening side.
Compared with prior art, have employed the spiral locking-type headstock assembly of technique scheme, there is following beneficial effect:
Adopt spiral locking-type headstock assembly of the present utility model, when bicycle pins by needs, only need to find the railing etc. that can lock to lock thing, locking thing is put into from the opening of annular handrail, locked component and handrail spiral mobile link, moved by the spiral of locked component and make handrail close any switching laws between open mode.After locked component locking, locking thing cannot take out in handrail, plays antitheft effect.User, without the need to carrying lockset in addition again, avoids unnecessary worry.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of spiral locking-type headstock assembly as shown in Fig. 1 to 7, comprise annular handrail 33, handrail 33 comprises the front end handle 331 of direct rod shape, front end handle 331 is provided with opening, the front end handle 331 of opening part is provided with to fasten and makes handrail 33 in the locking sleeve 35 closed, front end handle 331 is provided with outside thread, locking sleeve 35 inwall is provided with the negative thread matched with outside thread, locking sleeve 35 is connected with front end handle 331 spiral expanding, the latch-up structure of restricted locking sleeve 35 movement on front end handle 331.
By the cooperation of two place's screw threads, rotational lock sleeve 35, locking sleeve 35 can be made to slide, make annular handrail 33 closing any switching laws between open mode, when handrail 33 is in open mode, can put into the circle of handrail 33 as locking things such as railings, handrail 33 closed by slide-and-lock sleeve 35 more afterwards, make handrail 33 in closed condition, locking thing cannot take out in handrail 33, reaches the object of locking.
Latch-up structure is for limiting the movement of locking sleeve 35, and when latch-up structure is locked, locking sleeve 35 cannot move, and the locking such as railing thing cannot take out in handrail 33, reaches antitheft object.
Latch-up structure and locking sleeve 35 are all positioned on the front end handle 331 of opening the same side, latch-up structure comprises dead bolt 3312 and opens the lock core 3311 of dead bolt 3312 locking, it is inner that lock core 3311 and dead bolt 3312 are relatively arranged on front end handle 331, and lock core 3311 and dead bolt 3312 are positioned at front end handle 331 midway location of opening side.
Lock core 3311 is for controlling the flexible of dead bolt 3312, can rotational lock core 3311 by key, make dead bolt 3312 be free to stretch in front end handle 331 under the effect of key, the movement of locking sleeve 35 can be limited when dead bolt 3312 stretches out, reach the object of locking; Also can be made in dead bolt 3312 retraction front end handle 331 by key rotation lock core 3311, locking sleeve 35 is rotatable to be moved freely, and the locking such as railing thing can take out from the opening part of handrail 33.
Back-up ring on the front end handle 331 of opening side has position-limiting action to locking sleeve 35, prevents locking sleeve 35 from excessively rotating and deviating from front end handle 331.
The above makes preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
