Description
Technical field
This utility model relates to lock head structure, the lock head structure of a kind of anti-orcible entry.
Background technology
The tapered end modular construction of the most common spring lock as shown in Figure 11,12, including lock core set 5 be located at lock core set
Lock the lock core 6 in core bore.It is provided with spring 71, tack pellet 72 and semicircle in the marble hole of lock core set and the marble hole of lock core
Head pellet 73, is blocked spring 71, tack pellet 72 and cup head pellet 73 at lock core sleeving marble hole and lock core by plug
In marble hole.In the spacing hole of key slot 61 both sides, be separately installed with spring 81 and hoodle 82, by plug by spring 81 and
Hoodle 82 blocks in spacing hole, and spring 81 and hoodle 82 are used for limiting cup head pellet 73 and move down, and rely on cup head bullet
Son 73 limits lock core 6 and rotates.
The tapered end of this structure has the following disadvantages:
1. the direction unblanked at insertion key does not has any protection device, there is asking of torsion, not pick-proof the most anti-drilling, the most anti-
Topic.
2, in the latched condition, owing to the hoodle 82 distance of stretch out and draw back in spacing hole is the shortest, and spacing hole both sides are symmetrical and
Centre, again across key slot, therefore exists for bigger room between two spacing holes.When there being foreign body to stir, hoodle 82 is easy
Under the effect of spring 81 elastic force, jump to the outside of spacing hole, thus block key slot, make key normally to unblank.
3, in the lockout condition, spring 81 some can be exposed in key slot, if the steel wire that end is hook-type is stretched
Enter and key slot 61 is easy to ticked by spring 81, do not have the support of spring 81, hoodle 82 to retract in spacing hole, cup head bullet
Son 73 does not has the support of hoodle 82 to fall the most therewith, then stirs cup head pellet 73 with foreign body, makes cup head pellet 73 upper surface
When falling to the intersection of lock core sleeving marble hole and lock core marble, lock core is the most 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.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides the lock head structure of a kind of anti-orcible entry.It solves
Determined existing tapered end anti-damage performance and theftproof performance difference problem.
The technical solution of the utility model is: the lock head structure of anti-orcible entry, including including lock core, lock core set and rotary sleeve；
Lock core is multidiameter shape, and its one end is path section, and lock core is provided with key slot, and lock core puts and is provided with lock core hole, and lock core activity is pacified
It is contained in the lock core hole of lock core set；Rotary sleeve is provided with installing hole and front key slot, and installing hole is connected with front key slot, front key
The key slot of spoon groove and lock core adapts, and rotary sleeve passes through installing hole kink in the path section of lock core, and rotary sleeve is axially
On be positioned, and rotary sleeve be positioned at lock core set lock core hole in.
The further technical scheme of this utility model is: be communicated with the ball hole to installing hole on the outer wall of rotary sleeve,
The outer wall of lock core path section is provided with the ball grooves corresponding with ball hole position, is provided with ball in ball hole, and ball and ball
Groove contacts, and rotary sleeve is sleeved in the path section of lock core and is relatively rotated with lock core by ball；Ball be limited in ball grooves with
Between ball hole, provide axial location for rotary sleeve.
This utility model further technical scheme is: it also includes return assembly；
Interior marble hole, left installing hole and right installing hole it is additionally provided with on lock core；Interior marble hole is through to key from lock core outer surface
Spoon groove, left and right installing hole is symmetrically arranged at the both sides of interior marble hole, and left and right installing hole is respectively from interior marble hole and key
The intersection of groove is through to lock core outer surface；
Lock core puts and is additionally provided with outer marble hole, and the outer marble hole of lock core set is the most corresponding with the interior marble hole of lock core；
In the lockout condition, interior marble hole connects with outer marble hole, is sequentially arranged with stifled in outer marble hole and interior marble hole
Head, upper spring, upper pellet A and upper pellet B, 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 side
Right plug in installing hole, right spring, right pellet；Left plug and right plug are respectively used to close left installing hole and right installing hole.
This utility model further technical scheme is: the termination of left and right pellet is the most spherically.
This utility model further technical scheme is: the termination of upper pellet B is spherically.
This utility model compared with prior art has the advantage that
1, add rotary sleeve between lock core and lock core set, enhance the overall torsion anti-drilling, anti-of tapered end, pick-proof performance.Adopt
When boring lock with electric drill, although less drill bit can enter in the keyhole of lock core, but rotary sleeve can rotate under the vibration of electric drill,
So active force of drill bit can not be fixed at one, and drill bit easily twists off；Although bigger drill bit is unlikely to twist off, but can not stretch
Enter in key slot, still cannot destroy the structure of tapered end.
When 2, using foreign body twistlock by force, the width of foreign body must be narrower than the width of key slot, and foreign body is to stretch into lock
The key slot of core needs the front key slot first passing through on rotary sleeve, just because of there being the existence of front key slot, the length of foreign body will
Corresponding increase, foreign body is the most elongated, the most easily twists off when twistlock, and twistlock difficulty is big.
When 3, using with tapered foreign body twistlock, owing to the front key slot of rotary sleeve has certain degree of depth, foreign body is difficult to
Arriving the key slot of lock core, twistlock difficulty is big.
4, in sum, this utility model has excellent anti-damage performance and theftproof performance.
Below in conjunction with figure and embodiment, this utility model is further described.
