Abstract

The utility model relates to an interlocking electronic coded lock with an encrypted emergency lock, which avoids the difficulties in repairing the electronic coded lock in the market and solves the problem of losing the effect of the coded lock if an emergency lock is arranged. The utility model is characterized in that a safe mechanical coded lock interlocking device without a lock core is arranged between a stopper (3) controlled by an electronic coded lock electromagnet (12) and an emergency lock (4). When a fault occurs, through conditioning the code of the mechanical coded lock and turning an emergency key, the deflector rod (5) of the emergency lock enables an interlocking piece (6) to slide downward to push a disc (13), the stopper (3) is lowered down to a position below a latch baffle (2) and the lock can be opened conveniently. The utility model has the advantages that the lock can be widely used on products such as a safe deposit box, an iron cash case, a safety-deposit box, a storage cabinet, an antitheft door and the like, and the use is safe and reliable.

Description

Emergent lock is encrypted the interlock electronic password lock

One, technical field

The utility model belongs to lockset, relates in particular to a kind of emergent lock that is applied on the products such as casing, cupboard, door and encrypts the interlock electronic password lock.

Two, background technology

Traditional mechanical code lock is generally substituted by the electronic cipher lockset in the products such as various in the market strongboxs, safety cabinet, safe deposit box, Storage Cabinets, security door, and its structure is that the flexible link rod of keeper adds coded lock electromagnet block composition.Operating principle is after coded lock is imported correct number, the electromagnet power supply energising produces magnetic force, the electromagnet block is glided, thereby make the keeper link rod unobstructed, can freely stretch and realize the unlatching of door, have be suitable for convenient, open functions such as modification quick, that be convenient to password.Good effect is that coded lock does not have core, increases the technical opening difficulty, and theftproof performance improves greatly.The subject matter that exists is: electronic cipher lockset hidden danger is many, maintenance frequency is higher than mechanical code lock far away, for user under the prerequisite that breaks down can conveniently open keeper, so must be equipped with one emergent lock, and the routine lock that emergent lock is the common heart with lock, common product all is to take hidden installation now, just still be easy to find and by technical opening, as long as start emergent lock, electronic password lock just performs practically no function, thereby greatly reduces the due security performance of coded lock like this.

Three, summary of the invention

The purpose of this utility model is exactly that a kind of emergent lock that provides at the potential safety hazard of electronic password lock existence on the present market is encrypted the interlock electronic password lock.

The technical solution of the utility model is: emergent lock is encrypted the interlock electronic password lock and is added keyboard by control chip and forms with electronic password lock and emergent lock that display board constitutes, one of the increase mechanical code lock interlocking mechanism device of no core safely between the block of electronic password lock magnet control and emergent the lock.Described interlocking mechanism device comprises the disk on mechanical code lock, interlock sheet, emergent lock driving lever and the electromagnet block, described interlock sheet is " 7 " font, which is provided with two sliding trays, by bolt on door-plate, its bottom is on the disk of electromagnet block, and top is provided with reset tension spring, is provided with inserted sheet with mechanical code lock top groove corresponding position, be provided with the corresponding double-action plate lower knuckle of driving lever place in the emergent lock, form the gesture of interlock.

The beneficial effects of the utility model are: not only because emergent lock must just can make keeper open with mechanical code lock teamwork, even emergent lock is by technical opening, do not knowing that keeper is opened, thereby the safety of electronic password lock, convenient function are really brought into play, the product safety and reliability of applying electronic coded lock; And also have an emergent lock not need the advantage of the installation site determined, and effectively preventing to find easily behind the emergent lock of artificial destruction the position of electromagnet block, external force is stirred block and is opened keeper.

Below in conjunction with accompanying drawing the utility model is further described.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1 keeper, 2 keeper baffle plates, 3 blocks, 4 emergent locks, 5 emergent lock driving levers, 6 interlock sheets, 7 inserted sheets, 8 reset tension springs, 9 mechanical code locks, 10 sliding trays, 11 bolts, 12 electromagnet, 13 disks.

Five, the specific embodiment

As shown in Figure 1, look for a suitable space to set up a mechanical code lock 9 in the door inboard that electronic password lock is installed, make the interlock sheet 6 of " a 7 " font of the steel plate of the above thickness of 2.0mm, which is provided with two and slide up and down groove 10, be fixed on the door-plate by bolt 11, top is drilled with aperture and links to each other with pin on the door-plate by reset tension spring 8, the inserted sheet 7 of end place mechanical code lock 9 rotating disk directly over, the bottom is on the disk 13 on the block 3 of electromagnet 12 control, interlock sheet 6 bottoms bending slightly become to dial platform, and the emergent driving lever of locking on 45 is corresponding with being arranged at.Keeper 1 is installed within the door-plate, and keeper baffle plate 2 cooperates with the block 3 of electromagnet 12 controls, controls the flexible of keeper 1.When implementing the utility model, at first set the password of electronic password lock and mechanical code lock, push to door-plate then and get final product.When opening door under the normal condition, only need the password of input electronic lock, electromagnet 12 circuit turn-ons glide under the keeper baffle plate at block 3 under the effect of electromagnetic force, and keeper 1 can freely stretch under the effect of door upper handle, thereby conveniently door is opened.When electronic password lock breaks down, need open coded lock, at first mix up the password of mechanical code lock 9, three rotating disk grooves on mechanical code lock 9 tops are overlapped in the below of the inserted sheet 7 on the interlock sheet 6 at this moment, lock 4 lock core then with the key rotating emergency, the driving lever 5 that is arranged on the lock core glides the interlock sheet platform of dialling that clockwise direction rotates to interlock sheet 6 lower knuckle places, promote disk 13, thereby block slides to for 3 times under the keeper baffle plate 2, rotates keeper unlatching handle and makes within the keeper 1 indentation door-plate and door can be opened.After unclamping emergency key, the stage clip that is arranged at disk 13 belows on the block 3 resets block 3 jack-up, and interlock sheet 6 resets under the effect of reset tension spring 8, and the rotary machine sign indicating number is reduced to emergent safe condition.If do not mix up correct mechanical cipher, even open emergent lock, the inserted sheet 7 because the rotating disk of mechanical code lock 9 will link on the sheet 6 withstands, and the driving lever 5 in the emergent lock 4 can't press down block 3, and door lock still can't be opened.
