The back-locking device is a pressure plate driving and circling a spring fixed shaft to rotate, and is a prizing bar circling and driving the spring fixed shaft to rotate; the lock opening device is an auxiliary turntable arranged on the circular turntable. The utility model has the advantages of simple structure and high anti-theft performance.
Description
The utility model relates to a kind of lock, relates in particular to a kind of lock that is used for having on the security door anti-theft feature.
The general theftproof lock of Shi Yonging has following severally, and a kind of is common cattle head lock, and the dead bolt of this lock is the tapered plane dead bolt, though anti-lock device is housed, is also pried open easily; A kind of is the lock of two dead bolt structures of major-minor, and main dead bolt is the tapered plane dead bolt, and secondary dead bolt is a straight plane dead bolt, but this lock lacks anti-lock device, is outwarded winding easily.Also has a kind of lock of multi-faceted locking that is in addition.This kind is locked in anyhow that direction all is provided with dead bolt, but its structure more complicated, the cost height.
The purpose of this utility model just provides a kind of simple in structure, the theftproof lock that theftproof performance is good.
Core of the present utility model is a round turntable, on round turntable, be provided with arc-shaped slot, fixture on the dead bolt just is enclosed within the notch, the oblong dial rotation, dead bolt back and forth the running locking and unblank, with the matching used unlocking apparatus that also has anti-lock device and start this anti-lock device of this round turntable.
Described anti-lock device is compressing tablet and ripping bar that strip winding spring fixed axis rotates that the fixed axis of a strip winding spring rotates, and compressing tablet is stuck in bayonet socket on the round turntable and just can reaches and lock purpose.
Described unlocking apparatus be one be contained on the round turntable and with the secondary rotating disk of the coaxial rotation of round turntable.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1, structural representation of the present utility model.
The utility model comprises round turntable 1, on round turntable 1, be provided with three arc groove mouths 2,3,4, be provided with a dead bolt 5 in the front of round turntable, there is a fixture 6 just to be enclosed within the notch 2 on the dead bolt 5, reverse side at round turntable also is provided with dead bolt 7 and locking bar 8 in addition, fixture 9 on the dead bolt 7 just is enclosed within the notch 3,23 of fixtures on the locking bar 8 are enclosed within the notch 4, be provided with two dead bolts 24 on the left side of locking bar 8, dead bolt 24 flexibly connects by rotating shaft 25 with locking bar 8, dead bolt 24 self can rotate around fixed axis 26 in addition, also be provided with two dead bolts 27 in the top of locking bar 8, dead bolt 27 flexibly connects by rotating shaft 28 with locking bar 8, and dead bolt 27 self can rotate around fixed axis 29 in addition.Also be provided with a secondary rotating disk 10 on round turntable 1, there is a big breach 11 centre of this pair rotating disk 10, and the projection 12 in the middle of the round turntable 1 is just in breach 11 the insides.The edge of round turntable 11 is provided with bayonet socket 13,14, with round turntable 1 matching used anti-lock device, just be stuck in the bayonet socket 13, described anti-lock device is the ripping bar 18 that the fixed axis 17 of the compressing tablet 16 that rotates of the fixed axis 15 of a strip winding spring and a strip winding spring rotates, ripping bar 18 can be overlapping when rotating to a certain degree with compressing tablet 16, when rotating to a certain degree, also can separate, there is a bar 22 on the right of ripping bar 18 in addition, stop ripping bar when turning to bar, can not continue to turn clockwise, also has normal opening apparatus with round turntable 1 is matching used, so-called normal opening apparatus is meant when the state that dead bolt is in out, can make no longer the rebound device of locking of dead bolt, this normal opening apparatus just is stuck on the bayonet socket 14, described normal opening apparatus is the splay configuration card 20 that a strip winding spring fixed axis 19 rotates, and what open this normal opening apparatus is the pressure bar 21 of a band spring.Operating principle of the present utility model is as follows: when the utility model dead bolt is in closed condition (shown in Figure 1 be in closed condition for dead bolt).Compressing tablet 16 is stuck in the position of bayonet socket 13, and this moment, round turntable 1 can not counterclockwise rotate, and dead bolt can't be opened to have only with key and start, and the centre that key inserts secondary rotating disk 10 and round turntable 1 clockwise rotates earlier; When secondary rotating disk 10 forwards the position of compressing tablet 16 to, back down compressing tablet 16, compressing tablet 16 is done be rotated counterclockwise, leave bayonet socket 13, open and lock.When compressing tablet 16 rotate to ripping bar 18 above the time, can be blocked by ripping bar 18, no longer bounce-back, be rotated counterclockwise key this moment, and drive secondary rotating disk 10 and do and be rotated counterclockwise, when in the secondary rotating disk 10 with breach 11 rotate to round turntable 1 in the middle of projection 12 when colliding, can drive round turntable 1 is rotated counterclockwise, the round turntable that is rotated counterclockwise, driving dead bolt 5 under the effect of notch 2 moves right, driving dead bolt 7 under the effect of notch 3 moves up, under the effect of notch 4, drive locking bar 8 to the lower right to moving, dead bolt 5, dead bolt 7 leaves lock tube, can drive dead bolt 24 to the lower right again to the locking bar 8 that moves and clockwise rotate around fixed axis 26 and leave lock tube, and dead bolt 27 rotates counterclockwise around fixed axis 29 and leaves lock tube.When dead bolt 5,7,24,27 all leave lock tube when unblanking, bayonet socket 14 on the round turntable edge, just rotate to splay configuration card 20 places, and blocked bayonet socket 14 by card 20, round turntable 1 can not be done to turn clockwise, make dead bolt be in opening, have only this moment by hand push and press pressure bar 21 or ought be at closing time, when pressure bar 21 is collided with lock tube, pressure bar 21 moves right and orders about card 20 and be rotated counterclockwise and leave bayonet socket 14, when card 20 leaves bayonet socket 14, dead bolt 5,7 and locking bar 8 respectively under the effect of separately spring separately to negative side's running of unblanking opposite and drive round turntable and turn clockwise, dead bolt inserts the lock tube locking, dead bolt 5,7 and locking bar 8 also can rotate locking by key, can't be stuck in bayonet socket 13 on because compressing tablet 16 is blocked by ripping bar 18 this moment, has only by manual rotation ripping bar ripping bar is rotated counterclockwise, compressing tablet 16 separates with ripping bar 18, and under the effect of spring, turn clockwise and be stuck on the bayonet socket 13 and lock, the utility model is simple in structure, theftproof performance is good.
