[detailed description of the invention]
The present invention is a kind of Steel-clad lock, as shown in Fig. 1 to 8, include the lock housing 1 be made up of base plate 11, cover plate 12 and side plate 13, be arranged on the friction tongue assembly 2 in lock housing 1, main tongue assembly 3(this be the main tongue assembly of three rod-types), my god, latch 6,7 and safety plug assembly 8, and pull-fork assembly 9; Described safety plug assembly 8 includes safety plug 81 and can rotate with hand the safety plug shift fork 82 releasing safety plug 81; Described pull-fork assembly 9 includes interior shift fork 91, outer shift fork 92, middle shift fork 93, and the inside and outside plectrum 94,95 of friction tongue of friction tongue assembly 2 can be opened respectively under the effect of inside and outside shift fork 91,92, inside and outside shift fork 91,92 is basically identical with the hand holding lock of present stage when opening friction tongue assembly 2, is not described in detail in this; At this, be provided with in the left side of described middle shift fork 93 carrying and lock a door promotion boss 931 and press down the promotion boss 932 that opens the door, right side is provided with safety plug and opens promotion boss 933; The balance staff 114 of the base plate 11 be positioned on the left of pull-fork assembly 9 swings and is connected with interlock fork 10, described interlock fork 10 top is provided with to be clipped in carrying and locks a door promotion boss 931 and press down the stressed boss 101 opening the door and promote between boss 932, and the bottom set bar 20 be provided with on the main tongue assembly 3 of confession inserts wherein limit sliding edge and promotes the push-and-pull chute 102 that main tongue assembly 3 slided into, skidded off side plate; Described main tongue assembly 3 is provided with two be inserted into respectively sky, latch 6,7 sky, drive in push-and-pull skewed slot 61,71 sky, latch synchronously skid off the push-and-pull post 4 of locking a door or retracting and unlocking; Described base plate 11 is provided with and opens at the safety plug of middle shift fork 93 the safety plug interlock drive block 30 promoting down to slide along the guide pillar 115 on base plate 11 under boss 933 acts on; Be positioned at safety plug interlock drive block 30 below base plate 11 on be provided with hinged primary and secondary coupled arm 40,50, described main coupled arm 40 swings and is connected on the interlock balance staff 116 of base plate 11, and described safety plug interlock drive block 30 can act on the main coupled arm 40 that is positioned on the left of interlock balance staff 116 when down sliding; Described time coupled arm 50 other end stretchy safety plug shift fork 82 is flapped toward main coupled arm 40.
When the present invention is installed to and door uses, it locks a door outside door, open the door and all undertaken by key and outer handle, and the structure of this respect is basically identical with current similar lock, is not described in detail in this.And when will open the door in room, to realize by interior handle and without the need to key, as long as it is pressed down, at this moment:
On the one hand, in the tongue that rubs under interior shift fork 91 drives, friction tongue assembly 2 pulls back in side plate by plectrum 94, makes it to remove the locking to door;
On the other hand, middle shift fork 93 pressing down after following interior handle rotating on it is opened the door and is promoted stressed boss 101 that boss 932 acts on interlock fork 10 makes whole interlock fork 10 around balance staff 114 (namely toward away from side plate 13 direction) swing counterclockwise, at this moment the set bar 20 interted in the push-and-pull chute 102 of interlock fork 10 will pull whole main tongue assembly 3 slidably retractable in lock housing in side plate, makes main tongue module cancels to the locking of door; Main tongue assembly 3 in side plate slidably retractable in lock housing while, two push-and-pull posts 4 on it in sky, latch 6,7 sky, when sliding in push-and-pull skewed slot 61,71 by sky, latch 6,7 retract the middle part of lock housing, thus make sky, latch 6,7 remove locking to door, if shown in 3 to 5;
Again on the one hand, the safety plug of middle shift fork 93 after following interior handle rotating on the right side of it is opened and is promoted boss and be pressed in for 933 times on safety plug interlock drive block 30 and make it down to slide, thus pull safety plug shift fork 82 toward swinging away from side plate direction by primary and secondary coupled arm 40,50, safety plug 81 so just can be made to slide in side plate, thus make the locking of safety plug releasing to door, as shown in Figure 6,7;
Like this when friction tongue group main part 2, main tongue assembly 3, sky, latch 6,7, and safety plug assembly 8 is all removed and just can be opened door afterwards to the locking in room, thus realization directly presses down interior handle to open the door in room.
And when locking a door in room, as long as on carry interior handle, middle shift fork 93 after following interior handle rotating on it on carry locking a door and promote stressed boss 101 that boss 931 acts on interlock fork 10 makes whole interlock fork 10 around balance staff 114 (namely toward side plate 13 direction) swing clockwise, whole main tongue assembly 3 will make it to stretch out lock housing toward side plate extrapolation by the set bar 20 at this moment interted in the push-and-pull chute 102 of interlock fork 10, meanwhile, two push-and-pull posts 4 on main tongue assembly 3 are in sky, ground latch 6, the sky of 7, ground oblique pushing goove 61, by sky when sliding in 71, lock housing is released in latch front end, ground, main tongue assembly 3 and sky is realized with this, ground latch 6, the locking of 7 pairs of doors.
As can be seen from above, the present invention is provided with stretchy main tongue assembly 3 under the effect of middle shift fork 93 to stretch out or the interlock fork 10 and be provided with and can act on sky on main tongue assembly 3 of retraction side plate 13 in lock housing 1, ground latch 6, make their front ends slide on 7 simultaneously or skid off the push-and-pull post 4 of lock housing, and in lock housing, be provided with safety plug interlock drive block 30 and master, secondary coupled arm 40, 50, opening safety pin is carried out by them like this under the effect of middle shift fork 93, thus realize in room, handling handle in Steel-clad lock locking a door, open the door, therefore of the present invention rational in infrastructure, in very convenient operation, handle is in room inward opening door with lock a door, just in a rush without the need to getting to look for key and manual rotation insurance shift fork to open the door everywhere when there is emergency like this, thus the efficiency of in emergency circumstances escaping can be improved.
Described safety plug interlock drive block 30 is provided with the pushing pin 301 on main coupled arm 40 upper wall that can act on and be positioned on the left of interlock balance staff 116, as shown in Figure 6,7.
The connecting pin 501 in the jack 821 that can insert safety plug shift fork 82 lower end is provided with, as shown in Figure 7 in described secondary coupled arm 50 end.
Be only preferred embodiment of the present invention in sum, be not used for limiting practical range of the present invention, namely all equivalences done according to the content of the present patent application the scope of the claims change and modify, and all should belong to technology category of the present invention.
