In the technical solution, any second pellet group not with the same axial setting of any first pellet group, avoids second Pellet group and the interference of the first pellet group, it is random that pellet etc. in anti-dial lower pellet and vibrationproof can be selected in lower pellet 410, upper pellet 430 Combination, belongs to the prior art, does not just repeat one by one herein, and six group first 400, four group second of pellet group is equipped in the embodiment The quantity of pellet group 500 and two groups of third pellet groups 600, corresponding first marble hole 230 is also six, wherein the first marble hole three A to intersect with connecting hole, corresponding marble spring is held in interconnecting piece, and the outside of the first marble hole 230 is provided with obturator, should Pellet group is arranged in three polar axis directions of the anti-drilling anti-folding lock core of three face pearls, increases unlocking difficulty, improves the safe application performance of lock core, Lock housing is linked together by the connecting rod of high rigidity, reinforces the fracture resistance of lock body entirety, is equipped with elastic dialing core between two lock cores Group, the existing lock core locked and key is inserted in side because of someone can be solved in lock two sides while the function of unlocking by realizing Forget to pull out in hole and the shortcomings that the other side can not unlock.
Further, the hardness range of connecting rod 100 is HRC40~45.
In the technical solution, connecting rod selects No. 45 steel to be process, and by heat treatment process, guarantees the hardness of connecting rod 100 Range is HRC40~45, and in the prior art, lock housing is all that brass overall processing forms, and the material is soft for brass, easily snaps off, and adopts Split settings lock housing is linked together with the connecting rod of high rigidity, reinforces the fracture resistance of lock body entirety.
Further, it is recessed in lock core hole 220 and is correspondingly arranged respectively with the second pellet group 500 and third pellet group 600 V-shaped groove 221.
In the technical solution, when not unlocking, the second pellet group 500 and 600 bottom of third pellet group are arranged in corresponding V-arrangement 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.
