Abstract

The utility model relates to a cipher theft-proof door whose lockset device has a special structure. The position of a stopping clamp plate 8 which is corresponding to the drive catch plate 16 of a cipher lock is provided with the inner inverted catch plate of a protuberant cipher lock which is the last cipher-checking catch plate 19, and a wheel rim forms a toothed shape and is engaged with a ratchet bar 24. A protuberant clamp plate makes the criminal activity which checks the cipher by the auditory sensation and the hand feeling and the test feeling become impossible, and a ratchet cipher checking wheel makes the numerical code of a cipher lock disordered automatically in the operation of a locked door body. The utility model is suitable for the theft-proof door of various safes and classified offices.

Description

Theft-proof door with puzzle lock

The utility model is applicable to various safety cabinets and confidential accounts office.The molecule that can effectively avoid theft crime is to sign indicating number.Can dial a mao combination disk automatically during normal the use.Safe and reliable.

At present, the lock device on the known coded lock security door is by built-in lock, coded lock, and constitute with the dial drivening rod latch of the fixed coaxial rotation of handle.On control link, fix a stop clamp and coded lock side direction and be parallel to the axis arranged of coded lock.Open built-in lock when the digital rotating disk of operator password lock aligns the notch of each wheel disc of coded lock and stop clamp, turning handle is recoverable mortise lock, realizes opening the door.This lockset can rely on sensation and sense of hearing check mark to be unblanked.And during normal use whenever close the door and leave the on-the-spot action that upsets password that must be artificial, forget easily and cause great stolen leak.

And the utility model provides a kind of coded lock security door with special construction.Make with feel and sense of hearing examination sense check the number unblank to become impossible.And dial random combination disk automatically when making lock out action behind the door closing, thus thoroughly avoided closing behind the door owing to forget to dial to touch and cause stolen danger, alleviate staff's operation sequence and psychological burden greatly.

Basic function of the present utility model be achieved in that on the door body, be equipped with one with the dial of handle coaxial rotation, turning handle can drive latch by connecting rod and make expanding-contracting action, with the unlatching that reaches door and the purpose of locking.Wherein the stop clamp that moves with the control link axis that is parallel to coded lock is contained in the side of coded lock.And the neutral plane of clamp is parallel to the vibration-direction of clamp with connecting rod, by each axis to dialer of coded lock.Coded lock used herein has the zigzag wheel rim just the same with general code pins except that last a slice check mark.And the stop clamp with respect to first pair of dialer of coded lock promptly initiatively the dial place one outstanding 2-3mm double wedge is arranged.When the examination sense is checked the number, the digital calibration dish of necessary rotational password lock, driving first pair of dialer by mandrel rotates, the handle of while operated door, each that makes that control link drives that the stop clamp compresses coded lock is to dialer, at this moment the double wedge of clamp must be absorbed in the groove of first pair of dialer, rotates promptly to be stuck.Because of first pair of dialer is the active dial, thereby can not stir all the other each passive purposes that dialer realized check mark again.It is impossible that examination sense check mark becomes.The wheel rim of last check mark dial is made toothing in addition.At this elasticity that has that is meshed with it is housed above to dialer and allows the zigzag tooth bar of bit function, constituted the click structure.The profile of tooth end of tooth bar rides over profile of tooth on the dialer, and tail end and is fixed on the terminal hinged of rocking bar on the body.And have extension spring tension rocking bar and with the terminal fulcrum of control link on (latch ends of connecting rod is for terminal, and the thumb wheel traction end is a head end), the finger that move with connecting rod Shen one outside the head end middle part of control link.When turning handle was regained latch, finger was stirred rocking bar drive tooth bar and is moved, and does to dial random preparation.When turning handle used that link spigot pin is overhanging makes the lock door body action, because the stop clamp is contained in each groove to dialer, profile of tooth can not be rotated dialer, and tooth bar also can not move, and forces rocking bar to rotate and draws the Shen spring, and deposit is dialled random energy.Shen outside link spigot pin continues, when the stop clamp withdrawed from each to the dialer notch, spring tension discharged, and rotated ratchet-gear wheel, realized dialling automatically random action.Because what dial unrest is that last dials unrest to dialer, effect is very sufficient.If because recover the correct check mark position of this dish, must stir successively the front each to dialer driving last to dialer, just numerical digit of each dish of front has been upset naturally like this, realized dialling disorderly digital purpose comprehensively.

Further specify the novel performance of this use below in conjunction with drawings and Examples

Fig. 1 is a shape assumption diagram of the present utility model

Fig. 2 is a cut-away view of the present utility model

Fig. 3 is the A-A sectional view

Fig. 4 dials the detailed view of random mechanism automatically

1 doorframe among each figure, 2 bodies, 3 handles, 4 built-in locks, 5 coded locks, 6 peepholes, 7 steady shape hinges, 8 stop clamps, 9 thumb wheels, 10 control links, 11 stop claws, 12, connecting rod, 13 mortise locks, 14 digital dials, 15 rotating shafts, 16 initiatively check the number dial, 17 passive check mark dials, 18 passive check mark dials, the passive dial of 19 ratchet-shaped, 20 poles, 21 springs, 22 rocking bars, 23 fingers, 24 ratchet bars.

In mechanism shown in Figure 2, the action of contracting of the Shen of each latch 13, the control that is subjected to built-in lock 4 coded locks 5 and makes pawl 11 with fixed stop clamp 8 of control link 10 and stop.

Rotate dial shown in Figure 3 14 after built-in lock 4 is regained dead bolts again and drives successively initiatively by rotating shaft 15 that dial 16 and each passive check mark dial 17,18,19 make the elongated slot of the dial of respectively checking the number align stop clamp 8 when opening with key, at this moment turning handle 3(sees Fig. 1) get final product each latch 13 of withdrawal, realization such as drivening rod 10,12 with the coaxial fixed thumb wheel 9 of handle and open the door.At this moment since the elongated slot inner control connecting rod 10 that the stop clamp has been absorbed in the dial of respectively checking the number moved right, thereby stir rocking bar 22 with the fingers 23 that connecting rod 10 moves, tooth bar 24 is moved to right.Regain hour rack 24 fully when each link spigot pin and move on to maximum position to the right, be in the random state fully that gives of dialling.See Fig. 4.

When closing behind the door the lock door body, operating grip makes thumb wheel 9 counter-rotatings, and each latch 13 is overhanging, and control link 10 moves to left simultaneously.Move left initial stage at connecting rod 10, because stop clamp 8 is contained in each elongated slot to dialer, although at this moment the pole 20 with connecting rod 10 interlocks spurs springs 21, rocking bar 22 and ratchet bar 24, but ratchet figure disc 25 can not rotate, so ratchet bar 24 can not move, and spring 21 is elongated, store and dial random energy.Move to left each during to the square groove of dialer when control link 10 drives stop clamps 8, spring 21 shrinks and releases energy, and drives ratchet bar 24 and rotates ratchets to dialer 19, has realized group touching work.

Find out by Fig. 2 and Fig. 3, the check plate 8 on fixed and the control link 10, there is a double wedge at the position with coded lock active dial 16 relatively.The crime personnel that ought not know this lock cipher like this rotate dial 14 and try sense and check the number, and the double wedge of stop clamp 8 must at first be absorbed in the square groove of dial 16 initiatively, makes that initiatively dial 16 can not rotate, and the examination sense is checked the number and then can't be carried out.Effectively limited the crime activity.
