Description

The safety cabinet special-purpose theft-proof lock
The utility model relates to the safety cabinet special lockset.
Along with the progress of society, the technology of lock improves constantly, and the kind of lock is ever-changing, and in order to tackle constantly brilliant pilferage technology of burglar, people are in pick-proof, anti-saw, the technical multiple scheme of having taked such as anti-drilling.As the spring-free blade theftproof lock is at present advanced a kind of lockset, and it pulls out performance and anti-strong impact force lock anti-has had preferably the destruction of lock core and improve.But it is because structural restriction exists poor stability, baroque defective.
The safety cabinet special-purpose theft-proof lock that provides a kind of anti-destructive good, safe is provided the purpose of this utility model.
Goal of the invention of the present utility model is achieved by the following scheme: this theftproof lock comprise lock core, dead bolt, fixed lock core lock box and with the lock core cover of the supporting key of lock core, lock core in several pieces lock core chips are housed, be provided with 1 reed between per 2 lock core chips, the lock core cover is outer to be with and the fixing fixed cover of lock box, fixed cover bottom is jagged, and dead bolt passes this breach and the action by being inserted in the lock core cover lower end cylinder in the dead bolt transverse waist hole and the effect of a guide position limiter moves forward and backward dead bolt; One radial hole is arranged at lock core cover bottom, and spring is housed in the hole, and the aperture has axial straight trough, and the pin of riding is housed in the groove; One straight trough of aiming at lock core cover straight trough under locking-in state is arranged in the fixed cover, and straight trough opening one side is the inclined-plane.
Described guide position limiter can comprise a limited block, and it is fixed on the lock box with screw-nut by a backing plate, and the dead bolt afterbody has " L " shape hole that can slide on limited block.
Described fixed cover is Shape, its bottom is provided with two lugs that are connected with lock box, constitutes the breach that dead bolt passes between two lugs.
Described key is a kind of key with the angle-differentiated combination.
The utility model has the advantages that; Simple and reasonable for structure, have and good anti-ly pull out, anti-drilling, pick-proof, anti-ly pound performance, safety effect is splendid.

Embodiment to the utility model is described further below in conjunction with accompanying drawing:
As shown in the figure, lock core chip 5 of the present utility model is 9, and just breach circumferential position difference is answered the breach lock core chip by different key 22 insertion section breach pairings.The used key of this lock is to make up with different minute of angle, therefore except that size of key than common thread form key much bigger, also be difficult to imitatedly, strengthened confidentiality.Between per 2 lock core chips 5 a slice reed 6 is arranged, reed 6 is middle porose basin shape, and lock core chip 5 and reed 6 integral body are embedded in the lock core cover 11.Lock core overlaps 11 lower ends a cylinder 9, and it is inserted in the transverse waist hole 8 of dead bolt 7.Lock core overlaps 11 bottoms a radial hole 10, and a spring 18 is housed in the aperture 10, and there is an axial straight trough 17 in the hole for 10 mouthfuls, and the pin 15 of riding is housed in the groove, and fixed cover 4 is enclosed within on the lock core cover 11, is
Figure 0020855000041
Shape, in an axial straight trough 14 is arranged, a side of straight trough 14 opening parts is inclined-plane 16, opposite side is the right angle face.Fixed cover 4 two bottom sides have lug 19 respectively, have screw hole on the lug 19, and it is screwed in lock box 1, and 19 of two lugs constitute the breach that dead bolt 7 passes.Limited block 3 is fixed in the lock box 1 by a backing plate 2 usefulness screws, nut, can slide on limited block 3 in " L " shape hole 12 of dead bolt 7 afterbodys.
The operating principle of this theftproof lock is as follows: rotate counterclockwise key, next plays rotation to lock core chip 5 and lock core cover 11 in the effect of the pin 15 of riding, when lock core cover straight trough 17 secured in alignment put straight trough 14, the pin 15 of riding ejects in the spring force effect, be in the straight trough stop of lock core cover and fixed cover 9, be rotated further key, lock core chip 5 and then rotates, lock core cover breach 13 sides until lock core chip lug 21 latch, because the work plane of key is a plane, so the moon hole of 9 lock core chips 5 is arranged consistent, can extract key 22, be locking-in state this moment.
When key 22 inserts in lock core chip 5 holes, clockwise direction key 22, the different breach faces of the insertion portion of key 22 promote the rotation of side, lock core chip moon hole, it is consistent to put straight trough 17 until 9 lock core chip breach 20 and lock core, individual lock chip lug 21 promotes lock core cover 11 and clockwise rotates together, and the pin 15 of riding simultaneously skids off fixed cover breach inclined-plane 16, and drive dead bolt 7 contracts inward, be retracted in lock core cover and the lock core chip breach 20, until the pin 15 of riding until unlatching.Under opening, key can not pull out, because this moment, breach both sides, key insertion section were blocked by lock core chip.
