Description

Touching key-control self-lock mechanism for lock

Keyed self-locking mechanism is touched with lock by touch keyed self-locking mechanism, particularly door leaf that the utility model relates to a kind of lock.

Existing lock, particularly door lock has lock housing, locking bolt, locking bolt spring, lock pin, lock pin spring and stirs device, its locking bolt stretch out the wedge shape that the head major part is the monocline face, stirring device is the gear piece affixed with lock core, drive the gear piece of stirring device by key or handle, dial locking bolt and retreat and unblank, by reversing key or stir cage knob and make the locking bolt self-locking.Because the intensity of lock core or gear piece is low, the fastness of this lock is relatively poor, be easy to be knocked open by the robber, also from crack between a door and its frame lock is instigateeed with foil by the robber easily and open, and must help with key or handle when unblanking, overcome bigger spring force, locking bolt is retreated, lock is opened, be unfavorable for that faint electric power is unblanked or remote control open and close lock.

Task of the present utility model is exactly the self-locking shortcoming that will overcome above-mentioned lock, and that designs a kind of novelty touches keyed self-locking mechanism, so that come the unlatching and the locking of control lock with faint electric power or manpower, it is big to reach self-lock force, locks firm effect.

The structure of the inventor's one confrontational locking bolt adopts to have bibeveled locking bolt head shapes, and has utilized principles such as ratchet and pawl and lever, well-designed each structure member, thus successfully finished the foregoing invention task.The utility model comprises housing, locking bolt, locking bolt spring, lock pin, lock pin spring and stirs device, also have one can rotate on the housing around little axle, the rotating disk that has lock double wedge and control double wedge, the rotating disk torsion spring is arranged under the rotating disk, in the hole of rotating disk front portion pad is housed, can withstand the double wedge of locking of rotating disk with the ratchet of locking of locking bolt interlock, promote a certain angle of dial rotation, pad is depressed lock pin, block the locking groove of locking bolt, do not allow locking bolt retreat, the keying ratchet blocks the control double wedge simultaneously, do not allow rotating disk to revolution,, thereby reach the purpose of self-locking in order to avoid lock pin lifts.When unblanking, as long as stir the keying ratchet with very slight power, make it and control double wedge to break away from, rotating disk just back rotates under the effect of rotating disk torsion spring counterclockwise, thereby drive pad and leave lock pin, lock pin will lift under the effect of lock pin torsion spring, separates with the locking groove of locking bolt, locking bolt can retreat to right-hand, is unblanked.For stirring the keying ratchet, can adopt the ring that is connected with inserted link with lock core, also can adopt the micro electromagnetic coil, can also adopt the driving lever that is installed in relevant position on the lock housing.

Because the utility model is not with lock core or stirs the destruction opening force that device directly bears locking bolt, but bear this power by the high strength lock pin that is arranged between lock housing and the locking bolt locking groove, thereby its anti-sled ability and self-lock ability are all much bigger than common lock, and when normally unblanking, the power of stirring the keying ratchet is very little, can adopt the very little micro electromagnetic coil of power consumption to inhale the keying ratchet, rotating disk is turned round, discharge the pressure of pad, thereby be convenient to utilize little electric controllers such as capacitor-discharge unlocking apparatus or numerical control encryption apparatus to come the unlatching and the locking of control lock lock pin.With No. 5 dry cells of three joints, just can promote electromagnetic coil reliably and drive the action of keying ratchet; Also can touch driving lever with have gentle hands unblanks.

Be elaborated below in conjunction with embodiment and accompanying drawing.But interest field of the present utility model is not limited thereto.

Fig. 1 is that a kind of locking bolt head that designs according to the utility model is the bibeveled schematic diagram that touches keyed self-locking mechanism, and Fig. 2 is the sectional view along its A-A face, and Fig. 3 is that its B is to view.

With reference to accompanying drawing, being equipped with one in the chute 11 of housing 1 can be along the flexible locking bolt 2 of chute, the head 21 of its external part is made bibeveled shape, its other end has locking bolt spring 3 that locking bolt 2 is pressed to left side slip, if apply an enough big active force (as the F power among the figure) to the right for locking bolt 2, perhaps the inclined-plane to head 21 applies an enough big horizontal force (as P power or the P ' power among the figure), just the pressure that can make locking bolt 2 overcome spring 3 slides to the right, but, also be shaped on a wedge shaped stop groove 22 on the locking bolt 2, the lock pin 4 of a wedge shape also is housed on housing 1, its angle of wedge 41 falls into this locking groove 22 just, locking bolt 2 is withstood, and 42 of the arc surfaces of the right-hand member of lock pin 4 withstand in 1 the corresponding arc groove of housing or on the plane, so locking bolt 2 just can't move to left by locked.Lock pin 4 can rotate around bearing pin 43.The torsion spring 44 that is enclosed within on the bearing pin 43 can lift lock pin 4, makes its angle of wedge 41 break away from locking groove 22, thereby allows locking bolt 2 be moved to right, in order to unblanking.Just lift when needed, on housing 1, also be provided with little axle 12, the torsion spring 51 that rotating rotating disk 5 is housed on it and forces rotating disk 5 to rotate in the counterclockwise direction in order to control lock pin 4.The periphery place of rotating disk 5 lock double wedge 52 and control double wedge 53, the left of rotating disk 5 is porose 54, and band cap pad 55 moving up and down is housed in the hole, when rotating disk 5 is changeed a certain angle along clockwise direction, pad 55 is pressed on the lock pin 4 just, and the angle of wedge 41 is sunk in the locking groove 22 just; When rotating disk 5 is reversed by torsion spring 51 in the counterclockwise direction, pad 55 slip away lock pin 4 last plane 45 and can't press toward lock pin 4, under the effect of torsion spring 44, lock pin 4 lifts, the angle of wedge 41 withdraws from locking groove 22.In order to make pad 55 reliable operations, on rotating disk 5, also be provided with the sheet spring 56 of pushing down pad 55.For angle that rotating disk 5 is rotated counterclockwise is suitable, also has banking pin 57.Be pressed in position on the lock pin 4 in order to make rotating disk 5 be rotated clockwise to pad 55, being fixed with one in the side 23 of locking bolt 2 can be along the gulde edge 13 of housing 1 and the ratchet 6 of locking that slides with locking bolt 2 move left and right.When locking bolt 2 was moved to the left, the ratchet 6 of locking withstood the double wedge 52 of locking, and rotating disk 5 is turned clockwise; When locking bolt 2 moved left to extreme position, the ratchet 6 of locking broke away from the double wedge 52 of locking, and pad 55 just in time is pressed on the lock pin 4 simultaneously, and keying ratchet 7 then withstands control double wedge 53 just, and rotating disk 5 can not be reversed counterclockwise.Keying ratchet 7 is that one one end has dull and stereotyped 71 L shaped lever, and it can be around spindle 14 rotations that are fastened on the housing 1, and the torsion spring 72 that is enclosed within on the spindle 14 makes keying ratchet 7 have the trend of clockwise rotating, thereby always is pressed on the periphery of rotating disk 5.For keying ratchet 7 is separated with control double wedge 53, allow rotating disk 5 be rotated in the counterclockwise direction, the available ring 15 that connects with inserted link with lock core on the housing 1 that is installed in stirs dull and stereotyped 71, make 7 actions of keying ratchet, also can stir dull and stereotyped 71 with the driving lever 16 that is installed on the housing 1, can also inhale flat board 71 with the micro electromagnetic coil 17 that is fixed on the housing 1, so that realize cipher control or remote-control unlocking.

Accompanying drawing is depicted as the situation that self-locking mechanism is in the lock state, locking bolt 2 is stuck, door is lockable.Door when opening the door, touches driving lever 16, or with light twist lock core of key and ring 15, perhaps makes micro electromagnetic coil 17 produce magnetic force, keying ratchet 7 is rotated counterclockwise and thread off, so just can have been opened with control double wedge 53 with electric power with have gentle hands; Subsequently, because acting on the power of locking bolt head 21 disappears, locking bolt 2 is moved to the left under the effect of spring 3, is being with the ratchet 6 of locking to be moved to the left simultaneously, and the ratchet 6 of locking just heads on the double wedge 52 of locking makes rotating disk 5 clockwise rotate certain angle, when keying ratchet 7 fastens control double wedge 53 again, the ratchet 6 of locking breaks away from just with the double wedge 52 of locking, and this moment, pad 55 was depressed lock pin 4, and the angle of wedge 41 enters in the locking groove 22, locking bolt 2 is stuck again, finishes an actuation cycle.If need relay the bolt 2 that uncages, then need again light keying ratchet once, but also available driving lever 16 is pushed down flat board 71, and keying ratchet 7 is lifted, and can't withstand control double wedge 53, break away from the position of lock pin 4 so that allow rotating disk 5 under torsion spring 51 effects, can freely forward pad 55 to, perhaps push the ratchet 6 of locking aside, do not allow it be pushed up the method for the double wedge 52 of locking, make self-locking mechanism obtain permanent release, facilitate random open and close door like this, and needn't touch the control ratchet continually.

Locking bolt head of the present utility model also can be made into conically, spherical or prismatic except can be made into bibeveled pattern, as long as the lockhole on the doorframe acts on the power of opening the door of locking bolt head locking bolt is moved to right.The keyed self-locking mechanism of touching of the present utility model not only can be used in the door lock, also can be used for can also being used for other two members with relative motion, as locking device in other lock.
