The specific embodiment:
As shown in Figure 1-Figure 3: special type interlocking theftproof lock, by lock body 2, lock bridge 1 and locking closure 3 are formed.Insurance lockhole 4, main lockhole 5 and fabrication hole 6, totally 5 rooms are arranged on the lock body 2.In 3 sides of lock body 22 of lock beam holes (being used to insert lock bridge) are arranged respectively; One of dead bolt hole (being used for ring-shaped lock dead bolt ejects); Secondary 1 of lockhole (being used to open locking closure 3).Lock bridge 1 inserts in the lock body 2, in the insurance lockhole 4 and fabrication hole 6 on the locking closure pawl 7 insertion lock bodies 2 on the locking closure 3.Lock body 2 comprises that shell body 9, main lock move part, secondary lock, two-stage safeties and two-sided slide rail 20 and form.Main lock operation part, secondary lock, two-stage safeties and two-sided slide rail 20 all are in the shell body 9.The opening device of this lock usefulness is the interlock key.Main lock operation part comprises main lock core 16, main lock housing body 35, main lock spring 17, the rotating shaft 22 of main lock, ring-shaped lock dead bolt 11, full lock main shaft extension spring 12 and main driving lever 15.Main lock core 16 and main lock spring 17 are installed in the main lock housing body 35, and main lock core 16 compresses main lock spring 17, and the bending part of main driving lever 15 is inserted in the main lock core 16.Rotating shaft 22 is connected with main driving lever 15 extension spring 12 of full lock main shaft with main lock by screw.Ring-shaped lock dead bolt 11 slides in the rotating shaft 22 of main lock.Secondary lock comprises auxiliary lock core 19, secondary lockhole 21, spring locking plate 18 and push rod 23.Secondary lockhole 21 is in lock body 2 sides, corresponding to auxiliary lock core 19.Push rod 23 1 ends are fixed on the auxiliary lock core 19, and an end withstands on the spring locking plate 18.The two-stage safeties are in the both sides up and down of main lock rotating shaft 22 respectively, comprise insurance rotating shaft 10, insurance driving lever 13 and insurance torsion spring 14.Insurance torsion spring 14 is connected with insurance driving lever 13 by insurance rotating shaft 10, and insurance driving lever 13 moves up and down with the rotation of insurance rotating shaft 10.
Shown in Fig. 3, Fig. 4-1, Fig. 4-2 and Fig. 4-3: two-sided slide rail 20 is between main lock core 16 and ring-shaped lock dead bolt 11, and catch 26, aft ramp 27 and lock core passage 28 are insured in insurance catch 24, preceding slide rail 25, back before comprising.Slide rail 25 before preceding insurance catch 24 is positioned at, back insurance catch 26 is positioned at aft ramp 27.Lock core passage 28 is in the center of two-sided slide rail 20.
Shown in Fig. 5-1 and Fig. 5-2: the interlock key is made up of key base plate 33, key mainboard 29, key slide plate 30, internal tooth clavis spoon 31 and shift fork 32.Key base plate 33 and key mainboard 29 link together by screw.The U type prong of shift fork 32 links together by rectangular window and the key slide plate 30 on the key mainboard 29A face, and the thick head that the other end is enclosed within internal tooth clavis spoon 31 is gone up and welded together.
Operating principle:
1, unlocking function.As shown in Figure 3, when this lock was in closure state, the bending part of the main driving lever 15 that is connected with the rotating shaft 22 of main lock was inserted in the main lock core 16, and lock bridge 1 is locked in the main lock core 16 can't be extracted out.Open this lock, have only key is inserted in the rotating shaft 22 of main lock, and clockwise rotate, drive main driving lever 15 and move right and break away from main lock core 16, at this moment (as not considering the two-stage safeties) main lock core 16 ejects forward and ring-shaped lock dead bolt 11 is ejected outside the lock body under the effect of main lock spring 17.At this moment, lock bridge 1 can be extracted out, and this lock should be opened.But, because this lock has also designed the two-stage safeties,, main driving lever 15 satisfied a condition of unblanking so breaking away from 16 of main lock cores, if look on the bright side of things Qi Bensuo, must satisfy two other condition simultaneously and promptly the two-stage safeties must be opened.
2, insurance principle.Shown in Fig. 4-1, Fig. 4-2 and Fig. 4-3, its insurance function is realized by interacting by two-sided slide rail 20, preceding insurance catch 24, back insurance catch 26 and insurance rotating shaft 10.The residing position of forward and backward insurance catch is just in time blocked the outlet (being lock core passage 28) of main lock core 16, even main driving lever 15 breaks away from main lock core 16, main lock core 16 still can't eject.Key is inserted respectively in two insurance rotating shafts 10, and to right rotation, at this moment insure driving lever and will drive forward and backward insurance catch and move right, main lock core 16 is ejected by lock core passage 28; When stopping the rotation, under the effect of insurance torsion spring 14, about the insurance driving lever 13 insurance catch that will drive separately be moved to the left (homing).
3, secondary lock operating principle.If look on the bright side of things Qi Bensuo, at first to take off the locking closure 3 that covers on lockhole, just might insert key operated lock.The effect of secondary lock is exactly to pin locking closure 3.Shown in Fig. 6-1, Fig. 6-2 and Fig. 6-3,4 locking closure pawls 7 are inserted into insurance lockhole 4 and 6 four Kong Weizhong of fabrication hole in lock body front, and spring locking plate 18 is subjected to the extruding of one of them locking closure pawl 7, begin distortion gradually.After locking closure 3 ran down to the position, spring locking plate 18 is original position because the rebound effect of self has rebounded again, just in time the bending part of spring locking plate 18 was stuck in the groove of one of them locking closure pawl 7, had realized the locking function of locking closure 3.
Fig. 7-1 and Fig. 7 the-the 2nd, opens the fundamental diagram of locking closure, private key is inserted in the secondary lockhole 21, rotate counterclockwise, the push rod 23 that is fixed on the auxiliary lock core 19 moves from top to bottom, and push gradually along the inclined-plane of spring locking plate 18, spring locking plate 18 is out of shape and the groove of disengaging locking closure pawl 7, at this moment just can takes off locking closure 3.To extract out after the clockwise cycle original position of private key.
4, interlock key operating principle.The people has only two hands, can not rotate 3 keys simultaneously, and for guaranteeing that the user can open this lock smoothly, this lock has been equipped with special interlock key.Shown in Fig. 5-1 and Fig. 5-2, three link together internal tooth clavis spoon 31 by shift fork 32 and slide plate 30, rotate shift fork, will drive in addition that two shift forks rotate by key slide plate 30, rotate thereby drive internal tooth clavis spoon 31.Three dresses are listed in the internal tooth clavis spoon 31 that can rotate simultaneously together are inserted in insurance lockhole 4 and the main lockhole 5, just can open this lock.
Using method:
1, this lock is furnished with two kinds of keys, and a kind of is to open secondary lock, takes off that locking closure uses; Second kind is the interlock key, is used to open main lock and two-stage safety device.
The first step: private key is inserted in the secondary lockhole, counterclockwise to anticlockwise, take off cover the locking closure outside lock body and extract key out standby.
Second step: take out the interlock key, insert in insurance lockhole and the main lockhole, in the hole that is inserted into object on the shift fork, to right rotation, hear one after, see that the lock body left end face has dead bolt to eject, show that this lock opens, extract lock bridge out, promptly finish and unblank.
The 3rd step: shut.Dead bolt must not be pressed in the lock body before shutting, otherwise can't shut.At first lock bridge is passed the object that will lock, then lock bridge is inserted in the lock body, the dead bolt that ejects when unblanking promptly completely shuts by returning original position.
The 4th the step: at last locking closure is returned original position by opposite program button again, hear one, show that locking closure is locked.
