Abstract
The utility model belongs to the technical field of safety boxes, and particularly relates to a self-locking device for the safety box. According to the technical scheme, the self-locking device comprises a code disc lock which is arranged in a door body of the safety box, a lengthened lock rod which is arranged in the door body and can be inserted into a lock hole of a box body, and a control mechanism which controls the lengthened lock rod to be pushed into and pulled out from the lock hole of the box body to achieve locking and unlocking functions. A glass plate is arranged between the code disc lock and the door body. The lengthened lock rod is provided with a spring bolt mechanism which can control pushing and pulling movement of the lengthened lock rod. The spring bolt mechanism is controlled by a steel pull wire mechanism connected to the glass plate. According to the self-locking device, of the structure, for the safety box, the safety box can not be unlocked due to the fact that the lengthened lock rod is still located in the lock hole of the box body under the condition that the code disc lock is damaged.
Description
Technical field
The utility model belongs to safety cabinet technical field, relates in particular to a kind of use and is used in the self-locking device for safe in safe door body.
Background technology
Along with living standard improves day by day, the use of safety cabinet is no longer only confined to bank, unit, and entered family and become gradually the important component part in people's daily life, be used for depositing some as valuables such as cash, certificate, bullion, antique, calligraphies and paintings, and burglar often passes through to destroy lockset opening safety cabinet when left unguarded, cause great loss.And the controlling organization that forms safety cabinet lockset comprises code-disc lock, lengthens locking bar and controls the controlling organization that the push-and-pull turnover of this lengthening locking bar in the lockhole that forms cabinet realizes locking and open function.Yet, while opening prizing the strongbox due to robber, only code-disc lock need be destroyed, can by instrument, make controlling organization ineffective easily, and lengthening locking bar is pulled out to cabinet lockhole, thereby cause safety cabinet to lose safety effect.
Utility model content
Even if being just to provide a kind of code-disc lock destruction, the purpose of this utility model still can prevent from lengthening the self-locking device for safe that locking bar is pulled out in cabinet lockhole.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of self-locking device for safe, its structure comprises and is arranged at the code-disc lock that forms in safe door body, is arranged in a body and can inserts the lengthening locking bar of cabinet lockhole and control the push-and-pull turnover of this lengthenings locking bar in cabinet lockhole and realize and locking and the controlling organization of open function, it is characterized in that: between described code-disc lock and a described body, be provided with glass plate, at described lengthening locking bar place, be provided with and can control the spring bolt mechanism that its push-and-pull is moved, described spring bolt mechanism is by the steel wire tow line mechanism controls being connected on described glass plate.
The additional technical feature that forms this kind of self-locking device for safe also comprises:
---on described door body inwall, be provided with anti-drilling cover plate, described glass plate and this anti-drilling cover plate are fixedly integrally formed structure;
---described spring bolt mechanism by be arranged at lengthen locking bar middle part lockhole, be fixed on described dead bolt top and with the corresponding open frame of this lockhole and be arranged at forming from lock in this framework;
---described spring bolt mechanism lengthens the open frame of locking bar end and is arranged at forming from lock in this framework by being arranged at;
---described steel wire tow line mechanism comprises the some wrapping posts formations that are fixed on a body that are connected in the wire rope between described glass plate and spring bolt mechanism and control this steel wire rope tension.
A kind of self-locking device for safe provided by the utility model compared with prior art, owing to being provided with glass plate between code-disc lock and door body, at lengthening locking bar place, be provided with and can control the spring bolt mechanism that its push-and-pull is moved, spring bolt mechanism is by the steel wire tow line mechanism controls being connected on glass plate, even if code-disc lock is destroyed, its spring bolt mechanism can become the obstacle that lengthening locking bar is pulled out cabinet lockhole, and this lengthening locking bar can not pulled out from cabinet lockhole, thereby has played safety effect.
Accompanying drawing explanation
The structural representation of the self-locking device for safe that Fig. 1 provides for the utility model;
Fig. 2 is the structural representation of self-locking device for safe spring bolt mechanism.
The specific embodiment
Below in conjunction with accompanying drawing, the structure of self-locking device for safe provided by the utility model and use principle are described in further detail.
As shown in 1,2 figure, it is the structural representation of self-locking device for safe provided by the utility model.The structure of this device comprises: be arranged at the code-disc lock 1 forming in safe door body, be arranged in a body and can insert and in cabinet lockhole 2, be five of being arranged above and below and lengthen locking bars 3, on door body inwall corresponding to above-mentioned code-disc lock, be provided with anti-drilling cover plate 4, and on this cover plate, be fixed with the glass plate 5 being structure as a whole with it, the spring bolt mechanism forming from lock 8 that is provided with spring members 7 controls of being fixed by open frame 6 on end and the top of above-mentioned lengthening locking bar, glass plate 5 and form spring bolt mechanism from 8 of locks, be connected with steel wire tow line 9, this wire rope is controlled and is had certain tensile by being fixed on some wrapping posts 10 on a body.
Its operating principle is: robber is when prying open safety cabinet code-disc lock, can be in the lump by by screw with it fixing glass plate destroy broken, looseness of steel wire ropes now, entering under the effect of spring members 7 from lock 8 of making to be strained by wire rope by wrapping post is set in the lockhole 11 that lengthens locking bar middle part, or from lock 8 in the effect lower block of spring members 7 in the end that lengthens locking bar, this lengthening locking bar is fixed in cabinet lockhole 2, thereby it is firmly locked to realize keeper.
In forming the structure of above-mentioned self-locking device for safe:
---glass plate can directly be arranged between code-disc lock 1 and door body, and robber can be broken by glass plate when destroying code-disc lock, thereby to realize steel wire tow line 9 loosening in the same old way, and makes dead bolt under the effect of spring members, will lengthen locking bar locking.
