Safe case relocking device

Technical Field

The utility model relates to a safe deposit box technical field, concretely relates to safe deposit box relocking device.

Background

In order to improve the security of the safe, a relocking device is usually arranged in the safe, and the relocking device is an anti-accident lock arranged outside the original security lock of the safe. When someone illegally steals and tries to destroy the lockset of the safety box in a violent mode, the double-locking device plays a role, so that the double-locking of the safety box is realized, and the safety of the safety box is improved.

The existing safe re-locking device usually comprises a set of re-locking locks and a trigger device for starting and triggering the re-locking locks to act and take effect. When the safe encounters the unexpected conditions of vibration or high temperature and the like caused by external force, the trigger device takes effect, so that the lock is relocked to act, and the double locking of the safe is realized.

However, the existing safe case relocking device has the following defects: the triggering device is usually of irreversible design, i.e. the triggering device is "disposable". When the safe is in a violent damage condition, the triggering device is started to take effect. When the violent damage disappears, the trigger device can not be recovered. Thus, the safe cannot be used again. The trigger device can automatically take effect when the safe case is accidentally vibrated. Sometimes, in order to avoid damage to the safe caused by accidental everywhere, people can raise the trigger response threshold of the trigger device as much as possible, and although damage caused by false triggering can be reduced, sensitivity of trigger reflection is reduced, so that safety performance of the safe is affected.

It should be noted that the present invention relates to a one-level lock for locking a safe, which is an existing lock configured for the safe, and can be normally unlocked by an owner of the safe using a key, a password, or even an opening tool such as an IC card. Since the primary lock is prior art for safes, it will not be described in detail here. Of course, it is desirable to provide the control panel 16 on the door of the safe.

In addition, to ensure safety, relocking locks do not have unlocking tools. And the relocking lockset in the prior art cannot reset once being effective and can only be forcibly unlocked in a violent destruction mode. Thus, even if the relocking device is misactivated for various reasons, damage to the safe may occur. And the utility model discloses be equipped with in the control circuit of control relocking tool to lock action and be used for steerable the time relay of control circuit break-make. Therefore, when the controller starts the electrically controlled re-locking lock to realize the re-locking of the safety box, the time relay is started to start timing, when the set time is over, the time relay cuts off the power of the control loop for controlling the action of the re-locking lock, the re-locking lock is cut off to release the locking, the owner of the safety box can open the safety box through a normal way, and the destructive opening of the safety box caused by the false triggering of the re-locking device is effectively avoided. That is, the relocking device may achieve repeated activation and deactivation. The 'set time' can be conveniently and automatically set according to the requirement, so that the effective relocking of the safe is ensured, and the influence on the normal use of the safe owner due to the long-time locking of the relocking device is avoided.

As a first preferred scheme, as shown in fig. 2, the relocking lockset comprises a locking block 11 arranged on the side wall of the safe cabinet and an electric mortise lock 2 arranged on the inner side of the door 18 of the safe cabinet, when the controller receives signals output by a temperature sensor and/or a shock sensor, the controller enables the electric mortise lock to be electrically operated, and a bolt of the electric mortise lock extends to abut against the locking block, so that the locking of the relocking lockset is realized. Of course, after the 'set time' is passed, the controller can make the electric mortise lock act again so as to make the bolt retract and leave the locking block, and the re-locking lockset at the moment can automatically release the locking.

As a second preferred scheme, as shown in fig. 3, the vibration sensor comprises a swing rod 3 which is arranged approximately horizontally, the lower side of the middle part of the swing rod is rotatably connected to a rotating seat 12 arranged in the safety cabinet, a positioning groove 31 is arranged on the upper side of the swing rod corresponding to the rotating seat, two sides of the positioning groove on the swing rod are respectively provided with a roller path 32, a rolling ball 4 is arranged in the positioning groove, and travel switches 5 which are electrically connected with the controller are respectively arranged below two ends of the swing rod.

In addition, the relock lock includes a locking tongue 83 connected to a piston rod 82 that drives the cylinder.

When the safety box is subjected to violent damage of external force, such as gas cutting and the like, so that the temperature of the box door at the primary lockset rises, the heat absorption end absorbs heat, and therefore liquid refrigerant in the heat conduction pipe is evaporated into a gas state and rapidly flows to the output end, then enters the working cavity through the output end, the air pressure in the heat conduction pipe and the working cavity rises at the moment, the air cylinder is driven to enable the piston rod to extend outwards to drive the lock tongue to act, and the safety box enters a relocking state; when the outside temperature is reduced, the gaseous refrigerant in the working cavity and the heat conducting pipe is condensed into liquid, so that the air pressure is reduced, the piston rod of the driving cylinder is retracted to drive the lock tongue to automatically reset, and the safe case is unlocked.

It should be noted that a refrigerant such as freon R-113, having a boiling point of approximately 43 c, can be used to avoid evaporation of the refrigerant at normal room temperature and to ensure rapid evaporation of the refrigerant after heat absorption. In addition, a capillary layer with capillary action can be arranged on the inner side wall of the heat conducting pipe, so that the refrigerant can flow back through the capillary layer when the temperature is reduced and the refrigerant is condensed into liquid, and the refrigerant can be continuously evaporated into gas. In addition, a return pressure spring 86 can be arranged on a piston rod of the driving oil cylinder, so that the piston rod of the driving oil cylinder can automatically retract and return after extending outwards.
