Abstract
The invention relates to a single opening lock cylinder preventing single-hook opening. The single opening lock cylinder comprises a lock case (1), a lock cylinder (2), a shifting block (5) and a structural part (4), a groove (9) is formed in the rear end of the lock cylinder (2), at least two special-shaped shifting block cores (10) are arranged in an inner cavity of the shifting block (5), a projection or groove is formed on the periphery of each shifting block core (10), and the shifting block cores (10) are matched with the inner cavity of the shifting block (5). A thief can be effectively prevented from easily opening a lock by materials such as a single-hook lock pick or steel sheet from the outside, and cannot enter a house.
Description
Art
The present invention relates to a kind of anti-theft lock, especially a kind of list unlocking core preventing from singly hooking unlatching.
Background technology
At present, existing theftproof lock, is setting connector in lock core mostly, and connector is provided with groove, and key is to stretch
Enter to drive in the groove of connector shifting block core to unlock, this lock is easily beaten with single hook unlocking tool or steel disc by lawless person
Open, commit theft hence into interior.
Content of the invention
For disadvantages described above, the invention provides a kind of list unlocking core preventing from singly hooking unlatching, it can be effectively prevented
Robber from outdoor use list hook the material such as unlocking tool or steel disc lock is opened, overcome single unlocking core because structural limitation lead to antitheft
The drawbacks of effect difference, simple to operate, insurance is reliable, solve single unlocking core at present due to the limitation of self structure and lock core this
The anti-technology of body opens the technical problem of poor performance, lawless person cannot open with simple tool, it is to avoid robber is from outdoor
Easily lock is opened with single hook, get in.
For reaching object above, present invention employs a kind of technical scheme below: list unlocking core preventing from singly hooking unlatching, bag
Include lock housing, lock core, shifting block, structural member, described lock core rear end is provided with groove, described shifting block inner chamber is provided with shifting block core, described shifting block
Core is abnormal shape, at least two, shifting block core neighboring is provided with a projection or groove, described shifting block core and shifting block inner chamber kissing
Close, described shifting block core side is provided with retaining part, retaining part is arranged with spring, retaining part one end is stretched in groove, the other end with
Shifting block core is adjacent, and shifting block core opposite side is adjacent with structural member, and the other end of structural member is arranged with inner button, inner button and structural member
Between be provided with spring.
Shifting block core of the present invention includes left shifting block core and right shifting block core, and they are symmetricly set on axis；Described shifting block
The cross section of core is rectangle, polygon, spline shape, profile of tooth etc.；Described left shifting block core or right shifting block core often rotate 360 degrees only one
Individual position is matched with shifting block inner chamber；Described structural member is connected by connector with inner button.
Employ above technical scheme, the present invention, from outdoor insertion key or indoor promotion inner button, is pushed away by spring
Left shifting block core or right shifting block core are ejected shifting block by dynamic retaining part or structural member, thus reaching the purpose from outdoor and indoor unlocking.
Brief description
Fig. 1 is present configuration schematic diagram.
Fig. 2 is shifting block of the present invention match state diagram concavo-convex with shifting block core.
Specific embodiment
According to Fig. 1, a kind of list unlocking core preventing from singly hooking unlatching of the present invention, including lock housing 1, lock core 2, shifting block 5, tie
Component 4, described lock core 2 rear end is provided with groove 9, and described shifting block 5 inner chamber is provided with shifting block core 10, and described shifting block core 10 is abnormal shape, extremely
It is two less, shifting block core 10 neighboring is provided with a projection or groove, and described shifting block core 10 is matched with shifting block 5 inner chamber, institute
State shifting block core 10 side and be provided with retaining part 3, retaining part 3 is arranged with spring 6, retaining part 3 one end is stretched in groove 9, the other end
Adjacent with shifting block core 10, shifting block core 10 opposite side is adjacent with structural member 4, and the other end of structural member 4 is arranged with inner button 8, inward turning
It is provided with spring 7 between button 8 and structural member 4.
Shifting block core 10 of the present invention includes left shifting block core and right shifting block core, and they are symmetricly set on axis；Described group
The cross section of head core 10 is rectangle, polygon, spline shape, profile of tooth；Described left shifting block core or right shifting block core only often rotate 360 degrees
One position is matched with shifting block 5 inner chamber；Described structural member 4 is connected by connector with inner button 8.
The specific embodiment of the invention is as follows: when outdoor unlocking, key is stretched in lock core 2, is ejected by spring 6 and stop
Back pieces 3, right shifting block core is ejected shifting block 5, rotates key and rotates 360 degrees, and the projection of left shifting block core or groove are kissed with shifting block 5 inner chamber
After conjunction, shifting block 5 is moved by left shifting block core ribbon, thus lock is opened；When indoor unlocking, promote inner button 8, structural member 4 passes through
Spring 7 ejects, and left shifting block core is ejected shifting block 5, rotates inner button 8 and rotates 360 degrees, the projection of right shifting block core or groove and shifting block
After 5 inner chambers coincide, shifting block 5 is moved by right shifting block core ribbon, thus lock is opened.
