Abstract
The utility model relates to a blade type theft-proof lock which belongs to a special lock for strongboxes. The utility model comprises a lock shell, nuts, a set of lock sheets, a set of regulating sheets, a drilling preventing sheet, a lock core, a lock bar and a lock core fixing cap, wherein, the nuts match with turnbuckles in a screwed mode. The lock sheets and the regulating sheets are overlapped with each other in a staggered way and are arranged in the lock core. The drilling preventing sheet and the first regulating sheet are overlapped with each other and are arranged in the lock core. A positioning flange is arranged corresponding to a flange groove. The open end of the lock core is arranged inwards in the cylindrical cavity of the lock shell. The lock bar is positioned in the circular arc-shaped groove of a lock bar groove and the lock shell. The lock core fixing cap is positioned on the end of the lock core and is fixed with the lock shell by screws.

Besides, the utility model has the advantage of simple integral structure.
Description
The utility model discloses a kind of vane type theftproof lock, belong to the special lockset of safety cabinet.
The lockset of general insurance cabinet mostly is made of cylinder lock and dialing lock coupling.As the key operated lock of the usefulness of safety cabinet should have good anti-ly pull out, anti-saw, anti-drilling, pick-proof, anti-performance such as pound, yet cylinder lock is difficult to satisfy above-mentioned instructions for use because of its structural characteristics.For this reason, people become cylinder lock gradually and are the vane type theftproof lock, and the lock core of this lock can embody above-mentioned performance basically, thereby has certain anti-destructive and safety.But it is reasonable inadequately with cooperating of lock core that ubiquitous problem is a lock housing, and lock core is easily ejected from lock housing under the effect that is subjected to impact force backward, makes it lose due effect; And structure is all very complicated.
Task of the present utility model is to provide that a kind of lock core can not eject from lock housing backward because of external impacts, vane type theftproof lock simple in structure.
Task of the present utility model is finished like this, a kind of vane type theftproof lock, comprise: tool tubular cavity and arc groove 27 in one, outer tool spiral shell button 6, the lock housing 3 of top tool keyhole 25, one nut 7, one group of difference tool keyhole 21,19, recessed edge 17,20, locating flange 11,10 locking plate 12 and trimmer 9, one tool keyhole 23, the anti-drilling sheet 8 of recessed edge 24, one tool flange groove 13, the lock core 15 of a bolt groove 16 and an end opening, one bolt 14, one lock core locking cap 22, described nut 7 is joined with spiral shell button 6 spiral shells, one group of locking plate 12 and one group of trimmer 9 are a slice mutually every superimposed being placed in the lock core 15 in a slice ground, anti-drilling sheet 8 is located in the lock core 15 with first trimmer 9 with being superimposed, locating flange 11,10 corresponding to flange groove 13, lock core 15 openends are installed in the tubular cavity of lock housing 3 inwards, bolt 14 is positioned at the arc groove 27 of bolt groove 16 and lock housing 3, and it is solid that lock core locking cap 22 covers the terminal part and lock housing 3 spiral shells that place lock core 15.
The utility model has been owing to adopted said structure, and lock core 15 can be because of external impacts be ejected from the not end of lock housing 3, and this novel overall structure is comparatively simple.
Below in conjunction with accompanying drawing the utility model is further described below.
Fig. 1 is the utility model assembling assumption diagram.
Fig. 2 is cross section structure figure of the present utility model.
Fig. 3 is the structure chart that is used in key of the present utility model.
Fig. 4 is the structure chart of wherein a slice locking plate 12 of the present utility model.
Recessed edge 17 center lines on the every locking plate 12 of the present utility model and the angle α of locating flange 11 center lines increase progressively with 15 ° angle respectively, constitute one group of locking plate 12 that angle α has nothing in common with each other by this.If the angle α on first locking plate 12 is decided to be 135 °, angle α on all the other locking plates 12 is followed successively by 150 °, 165 °, 180 °, 195 °, 210 ° so, along with an amount of increase of locking plate 12 be aided with the angle factor and the setting of trimmer 9, make all corresponding the changing of quantity, angle of key tooth flower, thereby the tartar that can open key of the present utility model is difficult to duplicate, so key extremely difficulty duplicates, increased the safety of lock.
A locking closure 4 can be set up in the top of lock housing 3 of the present utility model, and keyhole 5 is arranged on it, and keyhole 5,25,23,19,21 is on the concentricity line.The effect of locking closure 4 not only can prevent dust, but also can play effects such as decoration.
When the utility model assembles, with used key is benchmark, select corresponding locking plate 12 and trimmer 9 for use by key tooth flower 2, after the cutting the face of cutting and match of the edge, location 18 that makes the keyhole 21 on each locking plate 12 and key tooth flower 2, the recessed edge 17 of all locking plates 12 is in same position, at this moment recessed edge 20 on recessed edge on the locking plate 12 17 and the trimmer 9 and the recessed edge on the anti-drilling sheet 8 24 form an axially groove of trend, and make this axially bolt groove 16 on groove alignment lock core 15 of trend and among the lock core 15 of packing into, locating flange 10 on trimmer 9 and the locking plate 12 like this, 11 all are arranged in flange groove 13.Take out key this moment, bolt 14 is inserted in bolt groove 16, and bolt groove 16 aimed at by the groove of recessed edge 24,20,17 formed axial trends the tubular cavity of the lock housing 3 of packing into, and it is solid with lock housing 3 spiral shells to be placed on the end of lock core 15 by lock core locking cap 22 at last.Trimmer 9 is one every a ground setting with locking plate 12, promptly by trimmer 9 each locking plate 12 is sandwiched in therebetween.Because every that cutting of key tooth flower 2 cut face width is narrow different, thereby the thickness of the locking plate 12 that matches with it also is not quite similar, so adjusted with the thickness variation of trimmer 9.
The utility model is to assemble like this on the safety cabinet, and realize its unlatching/locking, at first lock housing 3 is inserted from insuring in the prefabricated cashier's office in a shop locking shell hole, and the coronal-plane that makes the top of locking closure 4 and lock housing 3 is positioned at the outside of cabinet door, screw with nut 7 and spiral shell button 6 then, get final product until lock housing 3 is clamped on the cabinet door, at last lock core locking cap 22 is placed on the terminal of lock core 15 and is rotated with spiral shell button 6.During unlatching, hand is pinched the shank of the key 1, the spoon body of key is inserted to keyhole 5,25,23,19,21 also rotate, the edge, location 18 of each locking plate 12 is matched with key tooth flower 2, and recessed edge 17 on each locking plate 12 and the recessed edge 20 on each trimmer 9 and the recessed edge on the anti-drilling sheet 8 24 are overlapped, it is recessed edge 24,20,17 with lock core 15 on bolt groove 16 form a groove mutually, the arc groove 27 of bolt 14 this moment on the inwall of promotion lower edge, the edge of bolt groove 16 lock housing 3 done to slide counterclockwise, and clamp-oned in the described groove by wall by lock housing 3, thereby lock core 15 is free state.Be rotated further key, the backset that makes the pulling block 26 of lock core 15 ends stir the coded lock on the safety cabinet, lock promptly is unlocked; Reverse key and make recessed edge 24,20,17 return back to the coincidence position, key can take out.The key turns direction is opposite with opening direction during locking, make the recessed edge 20 mutual staggered positions on each locking plate 12, bolt 14 is released from described groove, and slips in the groove of bolt groove 16 and the arc groove 27 of lock housing 3, and pulling block 26 turns to and makes the backset of the coded lock on the safety cabinet sealed.
