Description

Can the tripartite security door that locks lock

The utility model relates to a kind of door lock, is a kind of being flush-mounted in the door leaf specifically, can realize the special-purpose lock of the fixed security door of three direction disposable locks.

The security door of active service, if carry out three directions lockings, polygamy is equipped with two locks, one limit lock locking laterally, one in lock locking upper and lower to, complex operation, the phenomenon that lock is forgotten to lock in often causing causes non-anti-theft, the pick-proof not of security door.Moreover used security door is with lock, after outdoor locking, most indoor be openable, thereby the burglar who can not the anti-creep window enters the room.

The purpose of this utility model is, designs a kind of being inlaid in the door leaf, can carry out simultaneously tripartite locking and can realize that the novel anti-theft door usefulness with stronger pick-proof that indoor and outdoor independently locks locks.To overcome existing deficiency with lockset.

Its objective is such realization: this lock comprises the rectangle lock box that is inlaid in the door leaf and the lid of front end, be contained in the tapered end in the lock box, be clamped in the plate of dialling of lock core rear end, be contained in the horizontal dead bolt in the lock box outside, and drive its flexible driving lever, eccentric block, driving handwheel, be contained in the travelling gear of dialling the plate rear end, with the rack-plate of its engagement.On the axle of travelling gear rear end, device has the driving handwheel.At rack-plate and homonymy horizontal dead bolt place, horizontal locking bolt is installed, on the front end face of opposite side, vertical with it pulley is installed, this pulley is held in and is contained in inboard " eight " font sliding guide groove that locate, the symmetry of vertical shift plate about in the of two of lock box, and both are slidingly matched by composition.Dialling on the corresponding end face of plate and travelling gear, be provided with corresponding double wedge.At the nearly excircle place of travelling gear driving wheel, the axial thread stop pin is housed, and on the rear end face of lock box, has the lock hole that matches with stop pin.

Security door of the present utility model is with locking, and owing to have group plate and warp to dial the travelling gear of plate driving in the lock core back-end device, the wheel and rack plate meshes, and device has the pulley of horizontal locking bolt and driving vertical shift plate on the rack-plate, thereby has realized three direction lock functions of lock.On the driving handwheel of travelling gear, be provided with the axial thread stop pin that can insert the lock box rear end face in addition, thereby the indoor and outdoor that guaranteed this lockset lock independently.

The security door of the tripartite locking of energy of the present utility model is provided by following examples and accompanying drawing thereof with lock.

Fig. 1 is according to the front view of the security door that the utility model proposes with lock.

Fig. 2 is the sectional view of Fig. 1 along A-A.

Fig. 3 is the sectional view of Fig. 1 along B-B.

Describe in detail according to the detail of the security door that the utility model proposes below in conjunction with Fig. 1～3 with lock.

Security door of the present utility model is with locking, comprise and be inlaid in the interior rectangle lock box [2] of door leaf and the lid [3] of front end, be contained in the tapered end [4] in the lock box middle part, be clamped in group plate [7] of lock core rear end, be contained in the horizontal dead bolt [6] in the lock box outside, and drive the driving lever [12] that dead bolt stretches, eccentric block [13], drive handwheel [14], be contained in the travelling gear [8] of dialling the plate rear end, with the rack-plate [9] of travelling gear engagement.On the axle of travelling gear rear end, device has driving handwheel [10].At rack-plate and homonymy horizontal dead bolt place, three horizontal locking bolts [5] are installed side by side, on the front end face of opposite side, the pulley vertical with this end face [15] is installed, this pulley is held in, in " eight " font sliding guide groove of the symmetry of the vertical shift plate about in the of two [1] at the inboard place of lock box lock box, both are slidingly matched by composition.Dialling on the corresponding end face of plate and travelling gear, be provided with corresponding double wedge.At the nearly excircle place of travelling gear driving handwheel, device has axial thread stop pin [11], in the corresponding position of lock box rear end face, has the lock hole that matches with stop pin.

The operation of this lock is as follows: during outdoor locking, key is inserted lockhole, rotate 270 ° in the direction of the clock, this moment, the double wedge on the plate [7] was dialled in the lock core rear end, double wedge on travelling gear, promote travelling gear [8] rotation, and driving gear batten [9] is made horizontal rectilinear motion laterally, three horizontal locking bolts [5] in its outside stretch in the horizontal lock hole on the doorframe, its inboard pulley [15] drives two vertical shift plates [1] simultaneously and stretches out up and down, drive two locking bolts up and down be attached thereto insert on the doorframe about in the of two in the lock hole, at this moment, lock core rotates to 360 °, transfer to key, this lock is in locking states, dials the double wedge of double wedge on wheel travelling gear [8] on the plate [7], limited the revolution of travelling gear, then indoor can't the unlatching.The operation of indoor locking is, rotating drive handwheel [10], and half-twist counter clockwise, this lock is finished the locking of three directions, then,, is screwed in the lock hole of lock box rear end then outdoor can't the unlatching with axial thread stop pin [11].Unlatching behind the outdoor locking, key is inserted lockhole, be rotated counterclockwise 360 °, dial plate [7] and drive travelling gear [8] rotation, drive in the rack-plate [9] and move, then laterally locking bolt [5], vertical shift plate [1] indentation simultaneously, key continues rotation, dial plate and promote dead bolt driving lever [12], drive horizontal dead bolt [6] indentation, this moment, the gate was opened.Indoor unlatching is rotated counterclockwise the driving handwheel [10] of travelling gear earlier, makes it half-twist, and then vertical shift plate and horizontal locking bolt indentation rotated horizontal dead bolt again and driven handwheel [14], laterally dead bolt indentation under the drive of eccentric block [13], and this moment, the gate was opened.
