Abstract
The invention discloses a forcible entry-preventing lock. The forcible entry-preventing lock comprises a lock core, a lock core sleeve and a rotary sleeve, wherein a key groove is formed in the lock core; a lock core hole is formed in the lock core sleeve; the lock core is movably arranged in the lock core hole of the lock core sleeve; a rotary sleeve installing hole section is formed on one end of the key groove of the lock core; a front key groove which is matched with the key groove of the lock core is formed in the rotary sleeve; the rotary sleeve is rotationally arranged in the rotary sleeve installing hole section. The forcible entry-preventing lock disclosed by the invention has the advantages that the rotary sleeve is additionally arranged in the lock core, so that integral properties of drilling resistance, torsion resistance and prying resistance of the forcible entry-preventing lock are enhanced. When an electric drill is adopted to drill a lock, although a smaller drill bit can enter a key hole of the lock core, but the rotary sleeve can rotate under the vibration of the electric drill, so that an acting force of the drill bit cannot be fixed to one position, and the drill bit is easy to twist off; although a larger drill bit cannot be twisted off, but the larger drill bit cannot stretch into the key groove, and a structure of the lock still cannot be destroyed.
Description
Technical field
The present invention relates to the tapered end parts of spring lock, particularly a kind of anti-orcible entry tapered end.
Background technology
The tapered end modular construction of spring lock common at present as shown in Figure 11,12, is overlapped 5 including lock core and is located at the lock core 6 that lock core puts in lock core hole.In the marble hole of lock core set and the marble hole of lock core, it is provided with spring 71, tack pellet 72 and cup head pellet 73, by plug, spring 71, tack pellet 72 and cup head pellet 73 is blocked in the marble hole of lock core sleeving marble hole and lock core.Spring 81 and hoodle 82 it is separately installed with in the spacing hole of key slot 61 both sides, by plug, spring 81 and hoodle 82 are blocked in spacing hole, spring 81 and hoodle 82 are used for limiting cup head pellet 73 and move down, and rely on cup head pellet 73 to limit lock core 6 and rotate.
The tapered end of this structure has the following disadvantages:
1. the direction unblanked at insertion key does not have any protection device, the problem that there is torsion, not pick-proof not anti-drilling, not anti-.
2, in the latched condition, owing to the hoodle 82 distance of stretch out and draw back in spacing hole is very short, and spacing hole both sides are symmetrical and centre is across key slot, therefore exist for bigger room between two spacing holes.When there being foreign body to stir, hoodle 82 easily jumps to the outside of spacing hole under the effect of spring 81 elastic force, thus blocking key slot, makes key normally to unblank.
3, in the lockout condition, spring 81 some can be exposed in key slot, key slot 61 is easy to ticked by spring 81 if being stretched into by the steel wire that end is hook-type, there is no the support of spring 81, hoodle 82 is retracted in spacing hole, and cup head pellet 73 does not have the support of hoodle 82 to fall therewith yet, then stirs cup head pellet 73 with foreign body, when making the intersection that cup head pellet 73 upper surface falls to lock core sleeving marble hole and lock core marble, lock core is namely rotatable.
In sum, the tapered end anti-damage performance (torsion anti-drilling, anti-, pick-proof performance) of this structure is poor, and theftproof performance is poor.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and a kind of anti-orcible entry tapered end is provided.It solve existing tapered end anti-damage performance and the problem of theftproof performance difference.
The technical scheme is that anti-orcible entry tapered end, including lock core and lock core set；Lock core is provided with key slot, and lock core puts and is provided with lock core hole, and lock core is movably arranged in the lock core hole of lock core set；
One end of plug keyway is provided with rotary sleeve installing hole section；It also includes rotary sleeve, and rotary sleeve is provided with the front key slot that the key slot with lock core adapts, and rotary sleeve is rotating to be arranged on rotary sleeve installing hole Duan Zhongzhong and is positioned in the axial direction.
The further technical scheme of the present invention is: being communicated with the ball hole to rotary sleeve installing hole section on outer wall of lock core, the outer wall of rotary sleeve is provided with the ball grooves corresponding with ball hole position；Being provided with ball in ball hole, and ball contacts with ball grooves, rotary sleeve is arranged in rotary sleeve installing hole section, and is relatively rotated by ball and lock core；Ball is limited between ball grooves and ball hole, provides axial location for rotary sleeve.
The present invention further technical scheme is: it also includes return assembly；
Lock core is additionally provided with interior marble hole, left installing hole and right installing hole；Interior marble hole is through to key slot from lock core outer surface, and left and right installing hole is symmetrically arranged at the both sides of interior marble hole, and left and right installing hole is through to lock core outer surface from the intersection of interior marble hole Yu key slot respectively；
Lock core puts and is additionally provided with outer marble hole, and the outer marble hole of lock core set is mutually corresponding with the interior marble hole of lock core；
In the lockout condition, interior marble hole connects with outer marble hole, outer marble hole and be sequentially arranged with upper plug head, upper spring, upper pellet A and upper pellet B in interior marble hole, and upper plug head is used for closing outer marble hole；
Left plug that return assembly includes being sequentially arranged in left installing hole, left spring, left pellet, and it is symmetrically mounted on the right plug in right installing hole, right spring, right pellet；Left plug and right plug are respectively used to close left installing hole and right installing hole.
The present invention further technical scheme is: the termination of left and right pellet is all spherically.
The present invention further technical scheme is: the termination of upper pellet B is spherically.
The present invention compared with prior art has the advantage that
1, in lock core, increase rotary sleeve, enhance the overall torsion anti-drilling, anti-of tapered end, pick-proof performance.When adopting electric drill to bore lock, although less drill bit can enter in the keyhole of lock core, but rotary sleeve can rotate under the vibration of electric drill, and the active force of such drill bit can not be fixed on a place, and drill bit easily twists off；Although bigger drill bit is unlikely to twist off, but can not stretch in key slot, still cannot destroy the structure of tapered end.
When 2, adopting foreign body twistlock by force, the width of foreign body must be narrower than the width of key slot, foreign body needs the front key slot first passing through on rotary sleeve to the key slot stretching into lock core, just because of there being the existence of front key slot, the length of foreign body will increase accordingly, foreign body is more elongated, more easily twists off when twistlock, and twistlock difficulty is big.
When 3, adopting the tapered foreign body twistlock of band, owing to the front key slot of rotary sleeve has certain degree of depth, foreign body is difficult to the key slot of arrival lock core, and twistlock difficulty is big.
4, in sum, the present invention has excellent anti-damage performance and theftproof performance.
Below in conjunction with figure, the invention will be further described with embodiment.
