Abstract
The invention discloses a coaxial two-cylinder invisible lock which comprises an inner lock cylinder and an outer lock cylinder. The lock is characterized in that the outer lock cylinder is provided with a lock hole, a through hole is formed in the circle center of the lock hole, a poking block is arranged at the upper end of the through hole, a groove is formed in the connection portion of the inner lock cylinder and the outer lock cylinder and enables the inner lock cylinder and the outer lock cylinder to move oppositely, a sheet gear is arranged in a lock body of the inner lock cylinder, a cavity matched with the fixed end of the outer lock cylinder is formed in the upper portion of the sheet gear, an invisible spring is disposed between the groove and the cavity, and a notch capable of containing the invisible spring is formed in the outer lock cylinder. The lock has the advantages that compared with a coaxial two-cylinder lock in the prior art, the manufacturing technology is simpler, and the percent of pass of finished products is greatly increased.
Description
Technical field
the present invention relates to theftproof lock field, particularly relate to a kind of coaxial double-core concealed lock.
Background technology
Mechanical lock right and wrong life appliance usually, the kind of mechanical lock is very many, but whether the quality of theftproof performance is that evaluation one is locking bad important indicator.The mechanical lock of traditional structure, by the cooperation of the pellet in key and lock core, makes lock core and lock tube relatively rotate, then drives tongue switching trip to realize unblanking and locking by lock core.But above-mentioned burglarproof function of lockset is poor, as long as apply certain moment of torsion to lock core, then with specific instrument pressure pellet, can realize unblanking.Unblank for preventing techniques, mechanical lock is improved, in prior art, there is coaxial double-core lock, but it does manual work too complicated.
Summary of the invention
The present invention is a kind of coaxial double-core concealed lock provided for solving the too complicated problem of lockset manufacturing process.
The present invention is solved the problems of the technologies described above by following technological means: a kind of coaxial double-core concealed lock, comprise internal cylinder and outer lock core, it is characterized in that, described outer lock core has lockhole, the circle centre position of described lockhole is provided with through hole, described through hole upper end is provided with shifting block, the connecting portion of described internal cylinder and described outer lock core is provided with the groove making described internal cylinder and described outer lock core can realize relative motion, described internal cylinder lock body inside is provided with sheet tooth, described tooth top is provided with the cavity coordinating described outer lock core fixed end, invisible billiards is provided with between described groove and described cavity, described outer lock core is provided with the breach that can hold described invisible billiards.This patent is the improvement carried out according to the coaxial double-core aperture migration theftproof lock of prior art, the principle of this key operated coaxial double-core lock core is, when inserting key, handle is connected with the outer lock core of coaxial double-core lock core, after rotating thereupon, the invisible billiards of front lock core locking rear lock core is opened in the rear end of key, be rotated further, key rotates and forms wrong hole together with lock core, whole lock core is opened, in whole process, key and handle are in the state of relative motion, two institute holes of coaxial double-core lock core are also dislocation all the time, namely the button on handle opens, otherwise handle rotates together with key, coaxial double-core lock core can not produce tandem motion, namely dislocation can not be produced, this lock cannot be opened.When extracting key, micro-button pressed on lower handle, turning handle, latch on the key in rotation process under the action of the spring, find groove on the key and embed, completing the fixing of key and handle, again because the various pellets in coaxial double-core lock core comprise the squeezing action of invisible billiards, key automatic rotary extremely inserts the position of unblanking, and the lockhole of the two-phase lock core in coaxial double-core lock core merges again.The transmission effect being originally outer lock core and internal cylinder of this key unlocking, internal cylinder is motionless and outer lock core rotates, invisible billiards opens under the rotation of outer lock core, skilled unlocking can only insert outer lock core, but cannot invisible billiards be touched, and to lock supporting key after unlatching with this be all misplace with lockhole.
Open the key that above-mentioned coaxial double-core concealed lock coordinates, comprise key body, it is axis being parallel and two sections of straight rods of opposite end connection, the horizontal direction of handle inner is provided with the cavity that can hold key body, the longitudinal section that straight rod inserts the part of cavity is circular, handle is provided with the latch with slot fit perpendicular to the position of groove, described latch is connected with spring in turn, baffle plate and button, described button extends to described handle outer, the top and bottom of the tail end of handle are respectively provided with two cylinders, key body has the groove being combined with two cylinders in the part of handle inner, certainly latch is being installed additional on the key, it is connected with spring in turn, baffle plate and button, button extends to handle outer and is also fine.Before key drives, lock core rotates, and its motion at rear lock core can only be carried out in the groove of rear lock core, and key opens invisible billiards while minimum point turns to peak; When closing lockset, when a little back stirring key, when invisible billiards falls back to outer lock core, breach can realize extracting of key automatically.
As a further improvement on the present invention, described cavity is through hole shape.
As a further improvement on the present invention, described cavity is quarter circular arc.
As a further improvement on the present invention, described cavity is 1/2nd circular arcs.
Beneficial effect of the present invention: the coaxial double-core lock in (1) hinge structure of the present invention, manufacture craft is more simple, and product qualified rate significantly rises; (2) making of the sheet toothing hinge structure in internal cylinder of the present invention is more prone to, and performance does not subtract simultaneously; (3) the present invention is particularly suitable for disposable unblanking, as padlock, safe lock and motor vehicles lock, easy to operate; (4) lockhole after the improvement of outer lock core of the present invention is convenient to make; (5) shifting block on outer lock core of the present invention can make the suitable of key rotate counterclockwise, and can realize the multiple security of lockset; (6) invisible billiards of the present invention has anti-drilling function.
