Abstract

The utility model provides a wheel hub lock provided with a wire rope and capable of improving the anti-theft coefficient. The wheel hub lock comprises a lock body, a lock core mechanism arranged on the lock body, and a lock pin mechanism; and the lock core mechanism is matched with the lock pin mechanism in a linked way, so as to realize the closing and opening of the wheel hub lock. The wheel hub lock is characterized in that the wheel hub lock further comprises a lock chain mechanism linked with the lock core mechanism in a synchronously-shutting and synchronously-opening way; the lock chain mechanism comprises a lock chain body; and at least one end of the lock chain body is connected with the lock body through a locking buckle. By adopting the technical scheme, at least one end of the lock chain body is connected with the lock body, so that while the lock pin locks the wheel hub, the lock chain body can further be bound and locked with an external fixed objector or an electric vehicle. Therefore, the function of a wire rope lock is performed on the basis of the prior wheel hub lock, and the anti-theft coefficient of the electric vehicle is greatly increased.

Description

A kind of hublock

Technical field

The utility model relates to a kind of lockset, especially a kind of hublock.

Background technology

Motor vehicle such as light motorcycle and electric bicycle is subjected to the welcome of town and country citizen and wage-earners day by day owing to light, inexpensive, has therefore obtained great development in recent years, and the market occupancy volume significantly improves.Such light motorcycle or electric bicycle generally carry the head lock that has with the ignition switch one at present, and the theftproof performance of this lock is very limited, and the stolen situation of vehicle happens occasionally.So for antitheft, car owners can add hublock or steel cable lock etc. usually in addition.Hublock includes lock body, lock core, lock pin and lock pin back-moving spring, described lock body is provided with the storage chamber of the lock core and the lock pin of perforation, lock core can be rotatably set in an end in storage chamber, the lock pin axial location, axially be slidably disposed on the other end in storage chamber, be provided with the interlock head with the lock pin abutting end on the lock core, on the lock pin with an an interlock abutting end suitable interlock containing cavity that is provided with and links, the interlock head stretches in the described interlock containing cavity, the side of interlock head is provided with projection, an interlock containing cavity sidewall is provided with a screw inclined plane, projection is fastened on the screw inclined plane and with lock pin and links, and the lock pin back-moving spring is between lock core and lock pin.Hublock locks the wheel hub on the motor vehicle, thereby realizes motor vehicle for to open the situation that hublock state lower hub can't be rotated, and then motor vehicle is carried out corresponding protection.Steel cable lock includes lock body, lock core and wirerope, and described lock core is installed in lock body, and an end of wirerope is fixedlyed connected with lock body, and the lock core on the other end and the lock body constitutes the lock fit of interlock.Steel cable lock then is by wirerope motor vehicle and fixture to be fixed, thereby makes motor vehicle can't break away from fixture not opening under the situation of steel cable lock, and then motor vehicle is carried out corresponding protection.

Yet nowadays burglar's means are more and more brilliant, and when people used hublock that motor vehicle is protected, the burglar can utilize the light characteristic of motor vehicle that car is locked and implement theft after lift the end; When utilizing steel cable lock that motor vehicle is protected, the burglar implements theft after utilizing instrument cut-out and spud pile to tie up the wirerope of establishing.Though above-mentioned dual mode has certain anti-theft effect, still stays opportunity to the lawless person easily.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of hublock that has wirerope and improve antitheft coefficient.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of hublock, include lock body and be located at lock core mechanism and latch gear on the lock body, lock core mechanism and latch gear be linked the locking of finishing hublock with unblank, it is characterized in that: also include with lock core mechanism and close together with the chain mechanism that opens interlock, chain mechanism includes the chain body, has at least an end and lock body to become snap close to be connected on the chain body.

Adopt technique scheme, the chain body has at least an end to be connected with lock body, when having realized that then lock pin locks wheel hub, the chain body can also be tied around locking with the external stability thing or to electric motor car, thereby be implemented in the function that has steel cable lock on the basis of hublock, improved the antitheft coefficient of electric motor car greatly.

Of the present utility modelly further be set to: an end of described chain body is the snap close end, the other end is provided with the collar, described snap close end is provided with pin, lock body is provided with the pin groove that inserts for pin, and pin groove place is provided with snap close piece, snap close piece and the interlock of lock core mechanism, when lock core mechanism is blocking, snap close piece enters the pin groove and forms snap fit with the pin that is inserted in the pin groove, and when lock core mechanism was unlocking condition, snap close piece withdrawed from the pin groove and is separated with pin.

Adopt technique scheme, the snap close end on the chain can be walked around fixture and pass the collar then, is inserted in then in the pin groove, the such fixed form of chain is simple and convenient, and can it be unloaded in fixing not needing, and then made things convenient for and carry, also reduced the volume of hublock with chain.Wherein, the pin groove on chain snap close end and the lock body constitutes plug and cooperates, and snap close piece in the pin groove and chain snap close end formation snap fit, and realization is fixed chain snap close end by the cooperation of lock core mechanism in the lock body and snap close piece.In the time of in pin inserts the pin groove, the locking plate dop will carry out locked to the locked groove on the pin, thereby realize the fixing of pin and lock body.

Of the present utility modelly further be set to: described lock core mechanism includes cylindric lock core, lock core can be rotatably set in the lock body, lock core one end is provided with axial cylindrical shape die cavity and constitutes the lock pin cavity volume, cylindric lock pin is circumferentially located, axially be arranged in the lock pin cavity volume movingly, described lock core and lock pin constitute lock core and rotatablely move and the lock pin axially-movable, lock core is provided with the spigot surface that is provided with along the circumferential spiral of lock core, pin is provided with locked groove, snap close piece is a locking plate, locking plate is provided with the locking plate pin and the locking plate dop of protrusion, locking plate is circumferentially located, axially be arranged on lock core one side movingly, locking plate upper collet pin is installed in the spigot surface place and with the inconsistent formation lock core of spigot surface and is rotatablely moved and the locking plate axially-movable, constitute the interlock of described snap close piece and lock core mechanism, the locking plate dop is provided with towards the pin groove center, the pin groove is positioned at locking plate institute on track, and locking plate dop and locked groove shape are suitable.

Adopt technique scheme, locking plate passes pin groove position through track, and the locking plate dop moves axially when lock core rotates and drive locking plate towards the setting of pin groove, locking plate dop on the locking plate enters in the pin groove, thereby realizes that lock body is to chain the locked of end of thread of locking.Wherein, chain can be fixed with other fixtures of periphery simultaneously, makes electric motor car has been carried out double insurance, if the burglar will commit theft, just need untie the locking on the hublock and the locking of chain simultaneously, and then improve the antitheft coefficient of electric motor car greatly.
