As shown in Fig. 5 .1, in the time turning the key in the lock, key inserts in the keyhole on tapered end, tapered end bar extend in turret apertures, and the two sides of tapered end bar, side 1 and side 2 27 lay respectively at the side, junction of evagination camber line 22 and inner concave curve 23 and correspond respectively to two evagination camber lines 22, in the time that key rotates counterclockwise, namely drive tapered end to rotate counterclockwise, thereby drive tapered end bar to rotate counterclockwise, tapered end bar is subject to stopping of inner concave curve 23, so tapered end bar drives rotating disk to rotate counterclockwise, thereby stirring dead bolt by driving lever inwardly shrinks, in the time that tapered end and tapered end bar rotate to the position as shown in Fig. 5 .2, dead bolt is retracted in lock body completely, completing key opens the door.Now, key can not be transferred to key.As shown in Fig. 5 .3, need clockwise rotate again key, make key get back to original position, drive tapered end bar to get back to original position, transfer to key, complete the action of opening the door.
In the time opening the door with badge, as shown in Fig. 5 .1, motor 17 is received turn signal, start to rotate, drive the rotating disk 12 being connected with a joggle with conical gear 11 to rotate counterclockwise, now, because tapered end bar is positioned at the right side of the junction of evagination camber line 22 and inner concave curve 23, do not stop the rotation of rotating disk 12, so tapered end bar maintains static, until dial rotation is to position shown in Fig. 5 .3, dead bolt is retracted in lock body completely, and realization is opened the door with badge, completes the action of opening the door.
The lock body of this integrated universal latch is divided into front panel 33, rear outer backboard 34 and rear board 35, on front panel 33, be provided with suspension column 36, corresponding with suspension column 36 positions, on rear outer backboard 34, be provided with suspension column hole, motor 17, rotating disk 12 and dead bolt 16 are all arranged in rear board 35, tapered end 25 is arranged on the outside of front panel, and the position of tapered end bar is corresponding with the position of the turret apertures arranging on rotating disk.When lock is installed, the front panel of lock is arranged on a surface, allow tapered end bar through the circular hole on rear outer backboard 34, then with screw, rear outer backboard is fixedly connected with four suspension columns 36 on front panel, then regulate tapered end bar 24, tapered end bar is inserted in the turret apertures 21 on rotating disk, then by fastening to rear board 35 and rear outer backboard 34 use M3 screw two sides, locking is fixed on a body.
Also the use that above-mentioned two kinds of tongue switching controlling organizations can be combined, now, lock both can open the door by key, can open the door by badge again.In the time wanting to turn the key in the lock, dead bolt is protruding, now, the position relationship of dead bolt bar and turret apertures is as shown in Fig. 5 .1, being rotated counterclockwise key drives tapered end bar to be rotated counterclockwise, can drive rotating disk 12 to rotate in the counterclockwise direction same angle, tapered end bar and turntable rotation are to the position shown in Fig. 5 .2, thereby drive dead bolt to shrink in lock body, realizing key opens the door, but should be noted, now, although having realized key opens the door, but now key should not be transferred to, need dextrorotation to turn 90 degrees, thereby drive the dextrorotation of tapered end bar to turn 90 degrees, make tapered end bar get back to the original position as shown in Fig. 5 .3, while namely getting back to key insertion lockhole, key could be transferred in the position of tapered end bar, if because just key is extracted after turning the key in the lock, work as dead bolt at closing time, inner concave curve 23 when motor turns clockwise in turret apertures 21 will come in contact with tapered end bar, cause high capacity stall to motor, although so now door opening function is realized, key also needs 90 ° of clockwise idle running to be returned to original position to drive tapered end bar to get back to the original position as shown in Fig. 5 .3, for gear turntable is that motor reserves the clockwise idle running space of 90 °, make dead bolt extended.In the time opening the door with badge, drive rotating disk 12 to be rotated counterclockwise 90 ° by motor, dead bolt is reversed in lock body, realizes badge and opens the door.
Adopt the turret apertures 21 of the utility model shape, can make rotating disk 12 under the drive of motor, turn clockwise 90 ° and do not contact tapered end bar 24, therefore tapered end can not rotate, thereby can not increase the extra load of motor, and because tapered end can be left-handed or turn right 180 °, therefore can make up the angular deviation with rotating disk 12 gaps generations by tapered end.See thus, in the time that motor drives rotating disk 12 to rotate, tapered end bar is motionless, and rotating disk and dead bolt bar do not interfere.In the time that key actuated tapered end bar rotates, thereby tapered end bar is applied to the active force of key on rotating disk 12 and realizes and opening the door by contacting with the inner concave curve in turret apertures.
When door is during in closed condition, dead bolt is protruding, enters the lock tongue cavity being positioned on doorframe, and in dead bolt is retracted into lock body time, door is unlocked.As shown in figs. 1 and 3, dead bolt stretch out or retraction is controlled by rotating disk 12.As shown in figures 1 and 3, be as the criterion with the position of dead bolt in Fig. 3 and driving lever, in the time that rotating disk 12 clockwise rotates, driving lever together clockwise rotates, and when driving lever goes to while contacting with the hypotenuse 2 29 of driving lever groove, driving lever is stirred dead bolt displacement to the right, dead bolt is retracted in lock body, thus door capable of being opened.
Tapered end 25 parts are installed on front panel backboard, and another part is connected with rotating disk 12 by dead bolt bar 24, and rotating disk is arranged in rear board 35.
As shown in Figure 3, driving lever groove preferably adopts following structure: it is made up of hypotenuse 1 and hypotenuse 2 29, connect hypotenuse one and hypotenuse two by curve 30, driving lever is along the radially setting of rotating disk, in the time that the end of driving lever contacts with hypotenuse two with hypotenuse one, hypotenuse one and hypotenuse two are all tangent with the end of rotating disk driving lever.The benefit that driving lever groove is set is like this, in the time promoting dead bolt by external force, dead bolt produces the trend of inwardly shrinking, because driving lever end and hypotenuse one are tangent connection, gear turntable is subject to the center of rotation 0 of the direction sensing gear turntable of the pressure F of dead bolt on the contact surface of driving lever and driving lever groove, be that F does not produce rotation torque, therefore gear turntable keeps static.Can prevent from unblanking with external force is undesired from the outside.In like manner, in dead bolt is recovered to lock body time, while pulling dead bolt by external force, rotating disk can not rotate, so dead bolt can not be pulled.Therefore, the driving lever of this structure and driving lever groove can be realized lock self-locking.
For driving lever is rotated in the angle of defined, and stir dead bolt and move back and forth with being beneficial to, be provided with only limit 32 at the free end of hypotenuse one and hypotenuse two.
As shown in Figure 6, for realize a lock can difference towards door on use, on the front panel 33 of the integrated universal latch of this structure, be provided with two tapered end holes 37, be respectively tapered end hole one and tapered end hole two, tapered end 25 is arranged in one of them tapered end hole 37, and tapered end hole one and tapered end hole two are all symmetrical arranged in the short transverse of door He on width, correspondingly, for the installation of door, suspension column is also all symmetrical arranged in the short transverse of door He on width.Like this, when open the door opposite direction time, tapered end can be arranged on to the position of the door opener on different tapered end hole endoadaptation rear boards, realize a lock general.
Tear lock open in order to prevent external force, microswitch 38 is set between front panel and rear board, microswitch is fixed on front panel 33, by door body, microswitch 38 is exerted pressure and is triggered, because front panel component are from the inside locking assembling of front panel 33, entirety is fixed by being loaded on indoor rear board again, there is no detachable screw in the outside of front panel, so in the time that front panel is dismantled by force, microswitch departs from door surface, trigger and disappear, warning is activated.
As shown in FIG. 8 and 9, microswitch 38 can be set equally on tapered end, microswitch is locked in Lock cylinder cover with Lock cylinder cover, make microswitch pressurized and in triggering state, in the time that badge open-door system is normal, attempt dismounting lock core lid opens the door by mechanical lock head without permission, will cause microswitch to trigger and disappear, activate and report to the police, realize anti-theft feature.Above-mentioned microswitch is connected with electric-control system.
Specific embodiment:
Door is under normal closed condition, and dead bolt stretches out.By brush badge, signal is passed to motor, after motor picked up signal, counter-rotate 90 °, because the effect of reduction box can obtain desired torque peace speed stabilizing degree, thereby band dynamic bevel gear rotates, and meshing gear rotates and makes dead bolt rectilinear motion, to lock body internal contraction; In the time that door enters closed condition, door magnetic acknowledge(ment) signal passes to motor, and motor is rotated in the forward 90 °, by the engagement of reduction box control bevel gear, thereby drives dead bolt straight line to stretch out.
In order to make badge and key all can realize and opening the door, the rotational angle of motor should match with the rotational angle of tapered end bar, as, in the time that turntable rotation 90 degree realizations are opened the door, locked a door, tapered end bar also opens the door by key by 90-degree rotation.
