Abstract

The utility model relates to a build-in anti-theft lock for bicycles, and belongs to metal material products. The utility model can lock a handle bar of the bicycle and cause the handle bar not to rotate, the self of the utility model is stored in steel pipes of the bicycle and is not damaged by external tools, and thus the anti-theft purpose for the bicycle is achieved. On the basis of the structural principle of the existing cylinder lock, the utility model is composed of an outer shell, a lock body, a lock core, a lock bolt, a cylinder, a spring and a key, wherein, the lock bolt is arranged on the middle position of the lock body, and the lock body is arranged in mounting holes of the bicycle. After the lock bolt buckles the inner wall of a steel pipe of a straight pipe of a front fork of a bicycle, a lock column positions the steel pipe of the handle bar of the bicycle to rotate, and the utility model achieves the anti-theft purpose that the bicycle can not run as the bicycle is locked.

Description

The built-in anti-theft column lock of bicycle

The utility model relates to the spring lock aufbauprinciple, be designed to small-sized tubular built-in anti-theft lock for bicycle, especially rotation that can the locking bicycle handlebar, bicycle can't be travelled, and lock the built-in of self, do not damaged, reach the built-in anti-theft column lock of bicycle of antitheft purpose by extraneous instrument.

At present, known anti-theft lock for bicycle, belong to spring lock structure class, as the crab tongs shape bicycle lock, positive open form bicycle lock, the bar shaped bicycle lock, the steel wire rope bicycle lock, chain bicycle lock and inserted link bicycle lock etc., by key, shell, lock body, lock core, locking bar (tongue, steel wire rope, chain, inserted link etc.), pellet shot from a slingshot, spring is formed, by the lock or the direct padlock locking wheel on bicycle that are installed on the bicycle, reach the antitheft purpose of bicycle, but because of lock and locking bar (tongue, steel wire rope, chain, inserted link etc.) all be installed in the outside, its lock or locking bar are very easily by screwdriver, hawkbill, instruments such as hacksaw destroy, thereby make lock lose antitheft effect, bicycle is stolen easily by the people.

The purpose of this utility model provides the built-in anti-theft column lock of a kind of bicycle, the rotation that it can the locking bicycle handlebar.Because its installation with bicycle handle bar's deflection locking, can't be carried out and be ridden away bicycle, and lock the built-in property of self, and external instrument can not be destroyed, and has guaranteed that locking bicycle reaches its antitheft purpose.

The utility model purpose is achieved in that the overall appearance of this lock is the cylinder bodily form, the side is shaped on vertical fin and the lock body interlude has dead bolt hole, length is 26mm, diameter is 14.8mm, the unlatching of this lock is common sheet gear shape key, and structural attitude of the present utility model is: be the spring lock aufbauprinciple, in the rigidity shell, leading portion lock body, lock core, dead bolt, back segment lock body, pellet shot from a slingshot, spring assembled in sequence are formed.Leading portion lock body, lock core, dead bolt and back segment lock body are formed the inner structure of lock.At front and rear sections lock body and lock core place one inside groove is arranged, dead bolt is installed in the inside groove, design has gear in lock core inside groove position, and also designing simultaneously on the dead bolt has gear, and promptly gear on the lock core and the gear on the dead bolt are to intermesh.The front and rear sections lock body of this lock is fixed in the shell by the shell punching press, and lock core is after being opened by matched key, can rotate, and the rotation of lock core will promote the dead bolt moving linearly, promptly do to open or locking, and the unlatching of key is controlled by the pellet shot from a slingshot of back segment lock body.With the locking device of common spring lock end points by lock, design is changed into the lock body midway location (promptly, between the back two-phase lock body), preceding, the intersegmental inside groove that is provided with of rear locking, movable dead bolt that is pushed with the lock core rotation of device in the groove, the dead bolt hole that is provided with on inside groove and lock core and the shell communicates, lock core is in the inside groove position, be provided with the transmission gear that is meshed with setting on the dead bolt, impetus by gear, because of the rotation of lock core promotes stretching out (i.e. locking) or shrink (promptly opening) whole principle of work and being of dead bolt: after will lock unlatching, pack in the mounting hole on the bicycle, key is to locking.Lock core is with the rotation of key, and the shell that the dead bolt promotion is stretched out lock comes, and after dead bolt fastens the steel pipe inwall of bicycle front fork straight tube, makes whole lock fixing motionless, by lock control locking bicycle handle bar, bicycle handle bar can not be rotated again, finishes the locking task.Otherwise dead bolt shrinks back in the shell of lock, extracts lock out, and bicycle handle bar is promptly rotatable, finishes the unlatching task.The utility model purpose reaches like this: with about 45 ° of bicycle handle bar's deflections, (diameter is the circular hole of 15mm to bore a mounting hole of the present utility model on the vehicle frame steel pipe outside of standpipe bottom of bicycle handle bar, outer interior two-layer steel pipe walls one side of vehicle frame and front fork straight tube is all drilled through, on the circular hole lower edge, file a wide dark little arc groove of about 2mm * 2mm simultaneously, be that whole erection hole shape and utility model front are harmonious), after mounting hole makes, the utility model Key for lock is opened back (being that dead bolt shrinks back in the shell of the lock) mounting hole of packing into, lock key is gone to latched position, the lock core of locking this moment is followed key and is rotated synchronously, gear on the lock core will promote the gear on the dead bolt, dead bolt is pushed out to the lock shell, the dead bolt of releasing the lock shell fastens the steel pipe inwall of bicycle front fork straight tube, at this moment, locking bit can not move in the pipe of steel pipe, control the rotation of bicycle front fork straight tube then by lock, promptly locked the rotation of bicycle handle bar, bicycle can't be pushed away away and ride away, reach the purpose of locking bicycle, play antitheft effect.Integral body because of lock is hidden in the steel pipe of bicycle simultaneously, and extraneous instrument can't destroy lock body, has ensured integraty and the normal function of locking self, further improves its antitheft effect.

Owing to adopt such scheme, can be when locking the bicycle front fork rotation, also locked the rotation of bicycle handle bar, it can't be travelled, locked self integral body in addition and be built in characteristic in the bike pipe and do not destroyed and ensured anti-theft feature by extraneous instrument.This lock is the spring lock aufbauprinciple, is metalwork, and is simple in structure.

Below in conjunction with accompanying drawing (accompanying drawing is lock-out state figure) and embodiment the utility model is further specified:
