Angular padlock head
Technical field
The present invention relates to a kind of angular padlock head, especially for the padlock head of bicycle steel cable lock.
Background technology
Existing blade angle lock is made up of following component basically: the lock core of tubular and lock core shell, some blades, some ring-type partitions and side column.Blade edge be provided with the side column diameter match but the position different half round cut that is angle, the centre is provided with key hole, the alternate lock core hole that places of blade and partition.The lock core barrel is provided with the axial long slot bore that matches with side column, and lock core is arranged in the lock core shell rotationally together with partition, blade etc., and lock core shell inwall and long slot bore relevant position are provided with the side column groove that matches with side column, and side column places between long slot bore and side column groove.Unblank preceding or when inserting non-matching key, the half round cut on the lock core tube intra vane is out of line, side column still is between long slot bore and the side column groove and blocks lock core, lock core can't be rotated and keeps locking not busy state; When inserting matched key, the half round cut on all blades will be in straight line and relative with the long slot bore position, and side column falls between long slot bore and the breach, break away from the side column groove, thereby lock core can rotate under the drive of key lock was opened this moment.The blade angle lockset has reliability higher, and therefore the advantage that mutual opening rate is low is used increasingly extensive.But blade angle is locked in and also exposes some shortcomings in the application: 1, because blade does not have radial location in lock core, be given a shock key hole arrangement disorder on the rear blade, key inserts very inconvenience; Revolution space than wide-angle also can be arranged when 2, key is not inserted into as yet, but lock fails still to open, cause the illusion that key lost efficacy or lock has damaged to the people.
Summary of the invention
The objective of the invention is to for overcome the deficiencies in the prior art provide a kind of be not afraid of can not rotate when vibrations, key are not inserted into as yet, can not cause key to lose efficacy or the blade angle lock and the key of the illusion that lock has damaged to the people.
Angular padlock head that the present invention provides for achieving the above object and key comprise lock core and lock core shell, some blades, some ring-type partitions and the side column of tubular, the location ruler that described lock core inner chamber is provided with rotating resetting-mechanism and links with it, described blade edge is provided with positioning convex, the positioning convex of blade leans against on the ruler of location, and the positioning convex of all blades is consistent with the relative position of key hole; Described lock core shell key insertion end end is fixed with catch, and catch is provided with the slotted hole shape keyhole that matches with the key cross section.
The further setting of the present invention: described resetting-mechanism is by being arranged on lock core intracavity bottom torsion spring rotationally and the torsion spring seat is formed, described location ruler is made of straight connecting portion of a bar shaped and the annulus that is connected two ends, described annulus is vertical with connecting portion, parallel with the lock core end face, circle diameter and lock core endoporus matched in clearance, described torsion spring seat outer end is provided with jack, the inserted sheet that the annulus outer face is provided with protrusion in the ruler of described location matches with jack, the inserted sheet of described location ruler is inserted in and constitutes interlock on the jack of torsion spring seat, described resetting-mechanism is made up of torsion spring that is arranged on the lock core intracavity bottom rotationally and torsion spring seat, described location ruler is made of straight connecting portion of a bar shaped and the annulus that is connected two ends, described annulus is vertical with the straight connecting portion of described bar shaped, parallel with the lock core end face, circle diameter and lock core endoporus matched in clearance, described torsion spring seat outer end is provided with jack, the inserted sheet that the annulus outer face is provided with protrusion in the ruler of described location matches with jack, the inserted sheet of described location ruler are inserted on the jack of torsion spring seat and constitute interlock.
Compared with prior art, the invention has the beneficial effects as follows: 1, because lock core shell key insertion end end is fixed with catch, catch is provided with the slotted hole shape keyhole that matches with the key cross section, and the key cross section is a pancake, can't rotate, as long as both sides are provided with the breach that matches with catch thickness on the position of corresponding catch when key is inserted into, make the cross-sectional maximum dimension at key this place be not more than the width of keyhole, assurance only could be rotated when key is inserted into; 2, because the location ruler that the lock core inner chamber is provided with rotating resetting-mechanism and links with it, described blade edge is provided with positioning convex, the positioning convex of blade leans against on the ruler of location, the positioning convex of all blades is consistent with the relative position of key hole, the key hole position consistency of all blades under the effect of location ruler, therefore the key insertion is very convenient, has overcome the deficiencies in the prior art.
