Description
Technical field
This application involves field of lockset, the in particular to a kind of anti-drilling anti-folding lock core of three face pearls.
Background technique
In daily life, in order to protect the safety of property often using various theftproof locks, spring lock and side column lock are
A kind of relatively common theftproof lock, lock core are the major parts that control lock is opened, it can be rotated and drive lock with key is mating
Bolt movement.Conventional spindle be usually on a direction with locking pellet component or both direction on have locking pellet group
Part, these structures all can make the safe application performance of lock core have a greatly reduced quality.Meanwhile present most lock cores are in the presence of very big
Security hidden trouble, some criminals are unlocked using illegal means, such as: using technology plug opening lock master, using vibration
Power driven tools or tinfoil tool are unlocked, using the means such as copy key or tool insertion lock core.
In addition, upper pellet is just ejected lock core marble hole by key, while will transmission when key is inserted into keyhole in place
Part pushes the lock core of another side to.At this moment, it turns key cylinder to be just able to rotate, while driving driving member, then by driving member band turn
Dynamic thumb wheel stirs lock tongue and opens lock.It is such movement in door, it is achievable outdoors.Therefore, door is inside and outside can turn lock core
And lock is opened.But when key is inserted in the lock core hole in door and has forgotten to pull out by someone, and people is at outdoor, even if this person
Also with one the key of adaptation be also difficult to from open outdoors this lock.The reason is that: that key in door by lock core from
The driving member on own one side pushes other end to, when it is inside and outside be inserted into key when, key is in the other end of lock core hole by oneself one side
Driving member withstands and cannot cause door that can not open in place.So needing to propose to improve.

In slot 221, lock core is lockked, when unlocking, key turns, the second pellet group 500 and third pellet group 600 skid off V-shaped groove 221, the
Two pellet groups 500 and 600 top card of third pellet group are set in keyhole, the bottom of the second pellet group 500 and third pellet group 600
Portion slides in lock core hole just.
Further, third marble hole 330 and the 4th marble hole 340 are stepped hole, third marble hole and the 4th pellet
Hole close to jack one end diameter be less than its diameter far from jack one end, the outer diameter at bottom outlet pellet both ends respectively with third pellet
The diameter of hole and the 4th marble hole is correspondingly arranged, and bottom outlet pellet both ends have protruded out the vertex of a cone respectively.
In the technical solution, third marble hole 330 and the 4th marble hole 340 carry out the second pellet group and third pellet group
Limit.
Further, the both ends of elastic dialing core group 900 are equipped with cushion block 1000, lock core between corresponding lock core 300 respectively
300 are recessed with first sliding groove 350 close to the end of pulling sleeve 700, and first sliding groove 350 and cushion block 1000 and elastic dialing core group 900 are right
It should be arranged.
In the technical solution, push cushion block after key insertion, so that the elasticity of compression dials core group 900 so that corresponding shifting block with
Pulling sleeve rotation is realized in pulling sleeve cooperation.
Further, lock core 300 is recessed with second sliding slot 360, second sliding slot 360 and shifting block close to the end face of pulling sleeve 700
800 are correspondingly arranged.
In the technical solution, by the effect of the first spring 810 and elastic dialing core group so that shifting block 800 is slideably positioned in
In two sliding slots, to realize the cooperation of shifting block and pulling sleeve.
Further, the first spring 810 is set to shifting block 800 between one end and second sliding slot of pulling sleeve 700, shifting block
800 periphery close to one end of pulling sleeve 700 is recessed with arc groove 820, and arc groove 820 is arranged in elastic dialing core group 900.
In the technical solution, when key is inserted into, the compression of elastic dialing core group is pushed by block, the first spring pushes shifting block to match
Pulling sleeve is closed, when key is extracted, elastic dialing core group pushes shifting block by arc groove 820, and shifting block and pulling sleeve are disengaged.
Further, elastic dialing core group 900 includes the two groups of cores 920 connected by rivet 910 and is set to two groups of cores
Between second spring 930, the opposite end face of two groups of cores is recessed with limiting slot 921 respectively, and the both ends of second spring are respectively set
In in two limiting slots.
In the technical solution, setting is spaced between two groups of cores 920, when two lock cores are inserted into key simultaneously, both sides block is same
Shi Zuoyong compresses the distance between two groups of cores, and both sides lock core is used cooperatively with pulling sleeve simultaneously, realizes that two sides are unlocked.
Further, the periphery of pulling sleeve 700, which has protruded out, dials tongue 710, and 700 center of pulling sleeve is equipped with through-hole 720, in through-hole
Wall center has protruded out annular boss 721, and boss two sides are recessed with the poke hole 722 being correspondingly arranged with shifting block 800 respectively, and two stir
Hole is arranged in the straight angle.
In the technical solution, poke hole 722 cooperates shifting block, realizes the rotation of pulling sleeve, in rotation process, dials tongue and lockset zero
Open and close lockset is realized in component cooperation.
Further, several anti-drill pins 1100 are equipped in lock housing 200 and lock core 300.
In the technical solution, different length, radius etc. is arranged according to different setting directions in anti-drill pin 1100, prevents sudden and violent
Power is unlocked.
The working principle of the anti-drilling anti-folding lock core of three face pearl of the utility model: after key is inserted into lock core, the block of corresponding side is pushed
Elastic dialing core group, so that in the corresponding poke hole of corresponding shifting block insertion pulling sleeve, in the bottom and key of the first pellet group
Keyhole cooperation, rotates key, and lock core rotation drives the second pellet group and third pellet group to skid off corresponding V-shaped groove, the second pellet
Group and third pellet group top card are set in keyhole, and the bottom of the second pellet group and third pellet group slides on lock core hole just
It is interior, lock core continuous rotation is realized, so as to unlock；And when the insertion of side lock core key, key, block are inserted into from the other side
The elasticity of compression dials core group, so that corresponding shifting block equally can be inserted in the corresponding poke hole of pulling sleeve, to realize that two sides are unlocked.
In conclusion pellet group is arranged in three polar axis directions of the anti-drilling anti-folding lock core of the three faces pearl, unlocking difficulty is increased, is improved
Lock housing is linked together by the safe application performance of lock core by the connecting rod of high rigidity, reinforces the fracture resistance of lock body entirety, two locks
Elastic dialing core group is equipped between core, existing lock can be solved because someone will in lock two sides while the function of unlocking by realizing
Key, which is inserted in the lock core hole of side, have been forgotten to pull out and the shortcomings that the other side can not unlock.
