Description
Technical field
The present invention relates to a kind of theftproof lock, it relates to a kind of spiral acute angle positioned at intervals theftproof lock in particular.
Background technology
The existing theftproof lock in market, the groove of lock core keyhole is spiral-shaped or rectilinear form, and the angle of keyhole bottom land is right angle, facilitating various keys can inject keyhole unblanks, and the right angle of bottom land pairing key tooth is also right-angle side along limit, the groove of two above identical right-angle sides of keyhole, makes the identical right angle of key tooth arbitrarily inject the groove of direction over there along limit and unblanks.The pellet of existing various locks or lock pin or sheet pin are all that device is in the groove of lock core.And do not hide the hidden pellet of keeping away, making key inject keyhole all must be through pellet or lock pin or sheet pin, and there is intersegmental gap on the pellet on lock core top to interior top simultaneously, and the tooth of key is that arrange down on the slope of ining succession, a slope.Becoming key top has one section of unnecessary inclined-plane in space, keyhole top, to have can to contact the range regulation insurance tooth pitch that pellet or mortice lock do to move forward and backward and unblanks.Lock core has anti-drilling framework, and device is in the peripheral phase slots of lock core, also has the anti-drilling axostylus axostyle of middle device at keyhole, but there is no Anti-drilling device to peripheral centre in the middle of key, is that the favourable lead plug of thief destroys lock core.The patent No.: 200410070079009.2 lock core is with each monomer adhesive, pin, welding or other fixing means are in conjunction with lock core moulding, according to the shape of keyhole setting and so that the combination tape edge of monomer to be longitudinally set, and be to be slot at the external surface of mandrel or the inner surface machined grooves of core retainer plate, and on mandrel or core retainer plate, machined grooves is not closed the setting that tongue phase place coordinates, and plug face end and inner equal diameters, can prize the lock core of combination, large head shapes is not set on each monomer, the setting that other end does not have the phase place of little head shapes to coordinate, there is no the mode of the fixed structure of clear and definite certain effects, be less than the thickness of an inserting column with regard to the thickness of the mandrel bonding surface in the middle of two slots, and secure bond is not firm, making to be greater than the die inserting column of a times steals tool and can destroy mandrel, article two, the thickness of die inserting column more has the large dynamics doubly mandrel that gets worse to separate core retainer plate, make that thief is favourable must be become.
Summary of the invention
A kind of spiral acute angle positioned at intervals drill-preventive anti-theft lock, is made up of lock body, lock core, lock pin, spring, key etc., wherein: in lock core, at least form the acute angle groove of a screw type, and described acute angle groove spiral is 180 degree spirals; The interval tooth of shape screw type in a row at least on the key, and described interval tooth is respectively arranged with acute angle along limit, and spiral is 180 degree spirals; Described lock core also has the lockpin hole of shape screw type in a row, and described lockpin hole is separately positioned on the side of acute angle groove; And described lockpin hole offers respectively lock pin mouth, and described lock pin mouth and acute angle groove connect; And described lockpin hole also has the lock pin being placed in, and one of described lock pin is provided with the face that tiltedly touches; Described lock body also has the interface locking pin-and-hole of screw type, and described interface locking pin-and-hole also has the interface lock pin being placed in; In described lock core, at least form a spiral trapezoidal anti-boring, and described trapezoidal anti-boring is large oral pore by tail end direction, and described large oral pore dwindles gradually and extends the little oral pore that is trapezoidal anti-boring to plug face extreme direction; Described trapezoidal anti-boring also has the trapezoidal anti-drill string being placed in, and described trapezoidal anti-drill string is and has microcephaly, and described microcephaly Let and little oral pore, and little oral pore extends to large oral pore gradually, and described large oral pore is the major part that has trapezoidal anti-drill string; Described key rotates to be at acute angle groove has acute angle to enter side lock pin mouth along the interval tooth on limit, be and have the interval of positioned at intervals tooth in place at lockpin hole respectively, and acute angle is praised tiltedly tactile face of lock pin relative engagement, realization insurance tooth pitch along limit.
A manufacture method for spiral acute angle positioned at intervals drill-preventive anti-theft lock, wherein: aperture apparatus core retainer plate in lock body, and core retainer plate is path by keyhole face end, is large footpath by keyhole the inner; Described core retainer plate inwall be provided with cover groove and cover raised line, and described cover groove and cover raised line respectively one be cover vat, other end is cover sulculus; Described core retainer plate endoporus Let closes lock core, and described lock core is by multiple trapezoidal combinations, and outer wall of lock core is provided with core groove and core tongue, and described core groove and core tongue respectively one be core vat, other end is core sulculus; Described core retainer plate is provided with core retainer plate lockpin hole, and described core retainer plate lockpin hole and lockpin hole align.
Described trapezoidal anti-drill string is that No. 45 steel quench.
Advantage of the present invention:
1, keyhole is the groove of acute angle shape, and be spiral-shaped or rectilinear form, the key of non-acute angle shape can not inject keyhole, and the orientation difference of every acute angle groove, makes every row's tooth of key tooth can not exchange reeve acute angle groove and cannot regulate insurance sawtooth to unblank.
2, lockpin hole is arranged on the side of acute angle groove, and lockpin hole is that interval shape arranges the lock pin of isolating respectively isolated system, make that lock pin is hidden to be kept away at lockpin hole, the tooth of key is that interval independently arranges simultaneously, the key of non-interval shape, just can not touch lock pin at keyhole, stealing tool also cannot touch the lock pin of isolated system respectively simultaneously, and plays the anti-theft effect of location.
3, on core retainer plate inwall, be provided with cover groove and cover tongue, be provided with core groove and core tongue that relative Let closes in lock core periphery, and be respectively divided into respectively major part and microcephaly at two at cover groove and cover tongue and core groove and core tongue, and obtain lock core and be fixed on the strong effect of core retainer plate, make key or steal tool and rotate and can destroyed lock core at keyhole.
4, trapezoidal in lock core, for trapezoidal shape phase Let is combined in the endoporus of the trumpet type arranging in core retainer plate, is the little oral pore in trumpet type hole by the face end of keyhole, and blocks the large footpath of trapezoidal, and can not prize trapezoidal.
5, trapezoidal of lock core is easy to be processed into the keyhole of various shapes.
6, lock core setting has spiral-shaped anti-drill string; one of anti-drill string is large head shapes; other end is little head shapes; and Let is combined in the small bore end of the anti-boring of plug face extreme direction relatively; outwards do not moved and block inner major part; avoid anti-drill string not extracted to face end, and protection lock core is not destroyed by lead plug.
7, anti-drill string is set to trapezoidal shape, favourable in lock core stationary positioned.
8, the lock pin of cylinder lock pin-and-hole arranges the face that tiltedly touches, and the interval tooth of key is provided with acute angle hypotenuse and coordinates and tiltedly touch face and praise insurance tooth pitch, and the key of non-acute angle hypotenuse cannot be praised lock pin tooth pitch and can not be unblanked.
