Abstract

An antitheft lock device comprises a left lock seat, a right lock seat and a lock bar consisting of a latch portion and a positioning portion. A rotatable lock cylinder is arranged inside the positioning portion, an extendable bolt is arranged on the lock cylinder, and an opening for the bolt to extend out is arranged on the positioning portion. A key hole is arranged at the end of the lock cylinder, and a right lock hole matched with the latch portion is transversely arranged on the right lock seat. A positioning hole and a left lock hole respectively matched with the positioning portion and the latch portion are transversely arranged on a left plate and a right plate of the left lock seat, and a first locking hole matched with the bolt is arranged on a front plate of the left lock seat. The antitheft lock device has the advantages that the lock bar with a lock cylinder structure can be stored in a trunk and the like when a user rides a bike in rainy days, and thereby mud and sands can be prevented from entering the lock cylinder structure, the lock cylinder is protected and service life of the antitheft lock device is prolonged, and further, when the lock bar is lost or damaged, the lock bar can be purchased separately, and thereby replacement cost is low.

Description

A kind of anti-theft lock device

(1) technical field

The utility model relates to a kind of anti-theft lock device, belongs to battery-driven car, bicycle, the used anti-theft column lock of motor bike field.

(2) background technology

At present, stolen in order to prevent bicycle, motor bike, battery-driven car, anti-theft column lock is installed in car to be stuck, can make wheel lock like this, the structure of anti-theft column lock mainly comprises corresponding respectively left lock and the right lock that is packed on the car fork both sides, be shaped on the installation through hole on left side lock and the right lock, be equipped with locking bar in this installation through hole, wheel is passed at the middle part of locking bar, play the effect that stops wheel, the part that locking bar is positioned at left lock is provided with locked groove, in the left lock lock core is installed, and realizes locking in the locked groove thereby the lock pin of lock core can stretch into to install in the through hole and place.Though this anti-theft column lock is very convenient in use, also there is shortcoming: the one, lock core structure is stuck at car by left lock extended immobilization, and in daily use, silt easily enters and causes lock core to get rusty in the lock core or stuck, causes disabler, and service life is short; The 2nd, when needing to change after anti-theft locking function lost efficacy, necessary integral replacing makes replacement cost higher.

(3) summary of the invention

Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides the anti-theft lock device that a kind of simple in structure, long service life, cost are low, be easy to change.

The technical scheme in the invention for solving the technical problem is: a kind of anti-theft lock device, comprise corresponding respectively left lock and the right lock that is packed on the car fork both sides, also comprise a locking bar of forming by lock bolt partial sum localization part, be provided with rotating lock core in the described localization part, this lock core is provided with exsertile lock pin, offer the opening that can supply described lock pin to stretch out on the described localization part, the end of described lock core is provided with key hole, the edge laterally is provided with the right lockhole that partly matches with described lock bolt on the described right lock, the left side of described left lock, along laterally being respectively equipped with knock hole and the left lockhole that partly matches with described localization part and described lock bolt, the front side plate of described left lock is provided with the lock hole one that matches with described lock pin on the right side board.

Further, the upper and lower side plate upper edge of described left lock vertically is provided with the jack that can partly pass through for described lock bolt, is positioned at described jack place on the epipleural of described left lock and extends upward and be provided with the slot that has upper shed and match with described localization part.

Further, a sidewall of described slot is provided with the lock hole two that matches with described lock pin.

Further, the cross-sectional plane of described lock bolt part is rounded, and the cross-sectional plane of described localization part is square.

The utility model is when locking, the lock bolt part of locking bar penetrates from the knock hole and the left lockhole of left lock successively, penetrate in the right lockhole of right lock through behind the wheel, the localization part of locking bar is positioned at the left side of left lockhole, and the lock pin of the lock core on the localization part of locking bar is positioned at left lock, uses key rotation lock core then, lock pin is ejected and embed in the lock hole one of left lock, making locking bar be locked on left lock, the right lock can't pull out, thereby pins wheel, reaches antitheft effect.When normally riding, the locking bar that has lock core structure can be inserted into the slot place of left lock, it is the jack that the lock bolt of locking bar partly passes left lock, and the localization part of locking bar places the interior also hanging support of slot on the epipleural of left lock, and make the lock pin of the lock core on the localization part of locking bar eject the lock hole two that is positioned on the slot, can prevent that locking bar from losing in the process of riding.When the rainy day, environment was ridden, the locking bar that has lock core structure can be deposited in boot etc. and locate, thereby stopping silt enters in the lock core structure, play the effect of protection lock core.

The beneficial effects of the utility model are: because lock core structure is arranged on the locking bar, when the rainy day rides, the locking bar that has lock core structure can be deposited in boot etc. locates, thereby stopping silt enters in the lock core structure, play the effect of protection lock core, prolonged service life of the present utility model; Simultaneously, when locking bar is lost or destroy, only need to buy separately locking bar and get final product, needn't change simultaneously, make that use is convenient, and replacement cost is lower being fixed in the left and right lock that car sticks.
