Description

Self-locking safe

The utility model relates to a kind of safety cabinet that is used to deposit valuables.

Though the pattern of safety cabinet is varied, its basic structure is identical, promptly mainly is made up of cabinet of working in coordination and cabinet door.The theftproof performance of safety cabinet is the most important technical indicator of safety cabinet, and therefore, the antitheft blocking mechanism of working in coordination with cabinet all is equipped with in the inboard of safety cabinet cabinet door.Antitheft blocking mechanism of the prior art is made of lock pin body and the combination lock and the mechanical latch of working in coordination with the lock pin body respectively usually, is a kind of blocking mechanism of double insurance.The lock pin body mainly comprises lock pin, handle, slide bar and pin rod, plural lock pin is parallel to connect into Jiong shape, it is inboard and can horizontally slip in lockpin sleeve so that lock pin enters or withdraw from the lockpin hole on the cabinet to be installed in the cabinet door by lockpin sleeve, and then makes safety cabinet locking or unlatching.Because the slip of lock pin is to realize by pulling the handle that is installed in the cabinet outer side of door, pass Over-The-Counter door earlier when therefore closing locker door, and then pull handle lock pin is entered in the lockpin hole on the cabinet.Iff being to close the Over-The-Counter door and do not pull handle, safety cabinet is can not locking, and can only be left unlocked or unlatched.This not only makes the complicated operationization of closing locker door, and causes easily and be left unlocked or unlatched and give stealer with opportunity.

But the purpose of this utility model is the safety cabinet of a kind of automatic blocking of design, with operation of conveniently closing locker door and the possibility of stopping to be left unlocked or unlatched the cabinet door.Strengthen the safety of safety cabinet.

To achieve these goals, the utility model is at the self-locking mechanism that a cover and blocking mechanism are worked in coordination of setting up on the basis of existing safety cabinet blocking mechanism, when closing the Over-The-Counter door, make the lock pin of blocking mechanism enter lockpin hole on the cabinet automatically, realize the automatic blocking of cabinet door by self-locking mechanism.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model self-locking safety cabinet.

Accompanying drawing 1 is the blocking mechanism of self-locking safety cabinet and the structural representation of self-locking mechanism.

With reference to the accompanying drawings 1, the blocking mechanism of the utility model self-locking safety cabinet comprises lock pin body and the combination lock 1 and the mechanical latch 2 of working in coordination with the lock pin body respectively, the keyhole of the figure disc of combination lock 1 and mechanical latch 2 is positioned at the cabinet outer side of door, and the lock pin body comprises lock pin, handle, slide bar and pin rod.Plural lock pin 3 is parallel to connect into Jiong shape, be installed in the inboard of cabinet door and can in lockpin sleeve 4, horizontally slip by lockpin sleeve 4, handle 5 is fixed on the cabinet outer side of door and can rotates around fixed point, and the one end links to each other with Jiong shape lock pin central authorities and can rotate around tie point.Slide bar 6 is installed in the offside of lock pin 3 by jack rod sleeve 7 and can horizontally slips in jack rod sleeve 7, and the one end links to each other with Jiong shape lock pin 3, and the other end is a free end.Pin rod 8 is installed in the offside of lock pin 3 and can overlaps in 9 at pin rod by pin rod cover 9 and horizontally slips, and the one end links to each other with Jiong shape lock pin 3, and the other end has two pole 12 and the poles 13 worked in coordination with combination lock breach 10 and machine machine latch dead bolt 11 respectively.

In order to realize automatic blocking, the self-locking mechanism that the utility model is provided with that a cover is made up of block, lance, self-lock rod, self-locking block, slide bar spring and pin rod spring and works in coordination with above-mentioned blocking mechanism.Block 14 is fixed on the upper limb of cabinet.The middle part of lance 15 is fixed on the inboard of cabinet door and can rotates around fixed point, works in coordination with block 14 in its upper end.The other end links to each other with self-lock rod and can rotate around tie point, self-lock rod 16 is installed in the below of lance 15 and can overlaps in 17 at bar by bar cover 17 and slides up and down, its lower end has the retaining of working in coordination with self-locking block 18, be set with a stage clip 19 on the self-lock rod of retaining 18 top, self-locking block 20 is fixed on the lock pin body slide bar 6 and works in coordination with self-lock rod 16 lower ends retaining 18.Slide bar spring 21 and pin rod spring 22 are set on lock pin body slide bar 6 and the pin rod 8.When closing the cabinet door, the upper end of lance 15 and block 14 collide mutually, lance 15 is rotated and make on the self-lock rod 16 and move, the retaining of self-lock rod 16 lower ends 18 breaks away from self-locking block 20 on the slide bar 6, the lock pin body promptly slides to the right under 22 effects of slide bar spring 21 and pin rod spring, and lock pin 3 is entered in the lockpin hole on the cabinet.Meanwhile, mechanical latch dead bolt 11 moves on automatically, stops that pole 13 moves to left, and has realized self-locking.The figure disc of this moment as rotation combination lock 1 can stop that then pole 12 moves to left, and realizes the dual locking of cabinet door.Set up after the self-locking mechanism, the unlock operation program of blocking mechanism does not change, but self-locking mechanism can make blocking mechanism be held open state, until closing the cabinet door.

Self-locking mechanism of the present utility model is simple, and is ingenious, work in coordination and can realize automatic blocking cabinet door with blocking mechanism, not only simplified the operation sequence of closing locker door, and stopped to be left unlocked or unlatched the possibility of cabinet door, strengthened the security reliability of safety cabinet.Therefore, the utility model is particularly suitable for depositing valuables.
