Background technology
Security door claims again anti-theft safety door, and it is with antitheft and safe performance.Lock on security door is divided into tri-grades of A, B, C conventionally, and mostly adopts lock cylinder, and the mutual opening rate of lock cylinder is higher, easily by lawless person's short time, is implemented to open, and makes security door lose original anti-theft function.
Summary of the invention
The deficiency existing for prior art, the utility model provide low, the antitheft coefficient of a kind of mutual opening rate high for the Anti-theft vane lock on security door.
For achieving the above object, the utility model provides following technical scheme: a kind of for the Anti-theft vane lock on security door, include housing, be installed on the latch bolt on housing, resistance tongue, the sliding panel being connected with resistance tongue, be located between latch bolt and sliding panel and the rotating shaft part of linkage latch bolt and sliding panel, described sliding panel place is provided with the lock core that can drive sliding panel slippage, it is characterized in that: described housing be positioned at sliding panel longitudinally a side be provided with key insertion hole, the side that sliding panel is positioned at key insertion hole is provided with some sawtooth, described lock core includes with the stacked setting of sliding panel and is articulated with at least a slice blade that can slide along housing on housing, the homonymy that is positioned at key insertion hole on the exterior contour of blade is provided with some external tooths, the axial end of blade is provided with the gear groove of some mutual conduction, sliding panel is provided with and extends in gear groove and can be along the limited block of each gear groove slippage.
Adopt technique scheme, lock core adopts blade construction, and blade is provided with the gear groove of several mutual conduction, with the sliding panel that is connected of resistance tongue be provided with can slippage in gear groove limited block, in use, key is inserted in housing by key insertion hole place, be provided with on the key with blade and sliding panel on the key tooth of sawtooth and external tooth adaptation, key revolves and turns around or semicircle can impel sliding panel to promote resistance tongue to move towards hull outside or internal implementation, limited block on sliding panel can be moved to by one of them gear groove of blade in another gear groove, because blade is at least a slice, mutual opening rate is low, and theftproof is good, and lawless person is difficult to adopt improper means that this type of lockset is opened.
The utility model is further set to: the installation place that housing is positioned at blade is provided with hinged pin, offers the chute with hinged pin adaptation on blade.
Adopt technique scheme, arrange so simple in structure, install and dismounting more for convenience.
The utility model is further set to: longitudinal two ends of housing cross section are respectively equipped with the latch being articulated and connected with sliding panel.
Adopt technique scheme, after arranging like this, resistance tongue also can impel latch to assist locking to the door body of security door in locking process, has improved theftproof performance.
The utility model is further set to: each gear groove on blade rectangular, between each gear groove, by being communicated with the vertically disposed link slot of gear groove, and the wall that each gear groove is connected with link slot is inclined to set.
Adopt technique scheme, it is convenient to hindering the locking of tongue or opening and implement to control to arrange like this, makes key more smooth and easy when opening.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1 a kind of for the Anti-theft vane lock on security door, include housing 1, be installed on the latch bolt 2 on housing 1, resistance tongue 3, the sliding panel 4 being connected with resistance tongue 3, be located between latch bolt 2 and sliding panel 4 and the rotating shaft part 7 of linkage latch bolt 2 and sliding panel 4, sliding panel 4 places are provided with the lock core 5 that can drive sliding panel 4 slippages, housing 1 be positioned at sliding panel 4 longitudinally a side be provided with key insertion hole 11, the side that sliding panel 4 is positioned at key insertion hole 11 is provided with some sawtooth 41, lock core 5 includes with the stacked setting of sliding panel 5 and is articulated with at least a slice blade 51 that can slide along housing 1 on housing 1, the homonymy that is positioned at key insertion hole 11 on the exterior contour of blade 51 is provided with some external tooths 511, the axial end of blade 51 is provided with the gear groove 512 of some mutual conduction, sliding panel 4 is provided with and extends in gear groove 512 and can be along the limited block 42 of each gear groove 512 slippages.In such scheme, lock core 5 adopts blade 51 structures, and blade 51 is provided with the gear groove 512 of several mutual conduction, with the sliding panel 4 that is connected of resistance tongue 3 be provided with can be in the 512 interior slippages of gear groove limited block 42, in use, key is inserted in housing 1 by key insertion hole 11 places, be provided with on the key with blade 51 and sliding panel 4 on the key tooth of sawtooth 41 and external tooth 511 adaptations, key revolves and turns around or semicircle can impel sliding panel 4 to promote resistance tongues 3 to move towards housing 1 outside or internal implementation, 42 of limited blocks on sliding panel 4 can be moved to by one of them gear groove 512 of blade 51 in another gear groove 512, because blade 51 is at least a slice, mutual opening rate is low, and theftproof is good, and lawless person is difficult to adopt improper means that this type of lockset is opened.
