Description
Technical field
The present invention relates to lock technology field, especially relate to a kind of 90 and spend the high strength pick-proof gear lock of unblanking.
Background technology
Often depend on the life-span of lock core and link thereof the application life of the lockset on security door.Concrete, common lockset comprises housing, in this housing, slides and is provided with the slide plate that can slide, the sidepiece of this slide plate is fixed with the dead bolt that can stretch out outside this housing, the avris of this slide plate is fixed with tooth bar.Simultaneously, in this housing, be fixed with plug body, this plug body has hollow cavity, the middle part of this hollow cavity has mating groove, and what this hollow cavity internal clearance coordinated is inserted with the lock core for inserting key, the middle part of this lock core is fixed with gear, and the external tooth of this gear is projecting inward from this mating groove, and this tooth bar and the engagement of this gear.,, after this lock core rotation of this key actuated, this tooth bar of this gear driven moves, and then, after this slide plate slides, realizes stretching out and retracting of this dead bolt.Wherein, gear used mostly is circular gear, thereby this mating groove must have enough degree of depth, to guarantee that the external tooth of this circular gear can be close to the rotation of 360 °, then guarantee that the dead bolt that the dead bolt stretching out is completely retracted completely or retract completely stretches out completely.Like this, certainly will cause this plug body narrower at the width at this mating groove place, intensity herein forms defect, and plug body is easy to fracture herein then, has finally reduced the application life of this lockset.
Summary of the invention
The object of this invention is to provide a kind of 90 and spend the high strength pick-proof gear lock of unblanking, the intensity that it has plug body is larger, thus the feature of growing the application life of lockset.
The technical solution adopted in the present invention is: 90 spend the high strength pick-proof gear lock of unblanking, comprise housing, in this housing, slide and be provided with the slide plate that can horizontally slip, the right side of this slide plate is fixed with the dead bolt that can stretch out outside this housing, the upside of this slide plate is fixed with tooth bar, simultaneously, the top that is positioned at this tooth bar in this housing is fixed with plug body, this plug body has hollow cavity, the middle part of this hollow cavity has the mating groove of lower openings, and what this hollow cavity internal clearance coordinated is inserted with lock core, the middle part of this lock core is fixed with gear, the external tooth of this gear is projecting inward from this mating groove, and this tooth bar and the engagement of this gear, described gear comprises circular axle center part and is positioned at the segment gear portion in this axle center part outer rim, the central angle alpha of this segment gear portion is: 90 °≤α≤180 °, simultaneously, the distance B at the upper side edge of this mating groove and the edge of this axle center part is: 0mm < D≤3mm, and, when this lock core carries out after 90 ° of rotations, this dead bolt stretches out or retracts and put in place.
The distance B at the upper side edge of described mating groove and the edge of this axle center part is: 1mm≤D≤2mm.
The advantage that the present invention has is: the intensity of plug body is larger, thereby the application life of lockset is longer.Of the present invention 90 spend the high strength pick-proof gear lock of unblanking by making can to open or close this lockset after the rotation smaller angle of gear, make this gear have segment gear portion and can meet the requirement of unblanking or locking.Like this, its degree of depth of closing groove can reduce as far as possible, thereby plug body can not reduced too much in the intensity at this mating groove place, has finally extended the application life of this plug body.

Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 to Fig. 7: 90 spend the high strength pick-proof gear lock of unblanking, and comprise housing 10.The interior slip of this housing 10 is provided with the slide plate 20 that can horizontally slip, and the right side of this slide plate 20 is fixed with the dead bolt 21 that can stretch out outside this housing 10, the upside of this slide plate 20 is fixed with tooth bar 22., this slide plate 20 reaches the object of locking after sliding and driving this dead bolt 21 to stretch out to the right.Otherwise, reach the object of unblanking when this slide plate 20 is moved to the left after this dead bolt 21 of drive is retracted.Simultaneously, the top that is positioned at this tooth bar 22 in this housing 10 is fixed with plug body 30, this plug body 30 has hollow cavity 31, and the middle part of this hollow cavity 31 has the mating groove 32 of lower openings, and this hollow cavity 31 internal clearances coordinate be inserted with the lock core 40 for inserting key., this lock core 40 of this key actuated rotates.The middle part of this lock core 40 is fixed with gear 41, and the external tooth of this gear 41 is projecting inward from this mating groove 32, and this tooth bar 22 engages with this gear 41.Obviously, the object of this mating groove 32 is that the external tooth of this gear 41 can protrude, and after these gear 41 rotations, makes this slide plate 20 produce mobile by this tooth bar 22.
Further say, this gear 41 comprises circular axle center part 411 and is positioned at the segment gear portion 412 in these axle center part 411 outer rims.That is the external tooth of this gear 41 is only arranged in a part of outer rim of this axle center part 411.And the central angle alpha of this segment gear portion 412 is: 90 °≤α≤180 °, the distance B at the edge of the upper side edge of this mating groove 32 and this axle center part 411 is: 0mm < D≤3mm.More excellent, the distance B at the edge of the upper side edge of this mating groove 32 and this axle center part 411 is: 1mm≤D≤2mm.That is, this segment gear portion 412 only can be no more than the rotation of 180 °, and the upper side edge of this mating groove 32 (i.e. the bottom of this mating groove 32) and the distance of this axle center part 411 are less.In other words, this plug body 30 is unlikely to too small at the width at these mating groove 32 places.And when this lock core 40 carries out after 90 ° of rotations, this dead bolt 21 stretches out or retracts and put in place.That is, by adjusting the stroke of this slide plate 20, this lock core 40 is carried out after 90 ° of rotations, this dead bolt 21 or be converted to complete retracted mode from stretching out state completely, or this dead bolt 21 is converted to from complete retracted mode the state that stretches out completely.Like this, 90 spend under the prerequisite of normal switch of the high strength pick-proof gear lock of unblanking not affecting this, the intensity of this plug body 30 is larger, and application life is longer then.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes manual of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
