Description

Multidimensional vane type tapered end

Technical field

The utility model relates to a kind of safe-guard door lock tapered end, relates in particular to a kind of vaned tapered end that assembles in the tapered end lock core.

Background technology

China's utility model patent (application number: disclose a kind of vane type tapered end 201120128903.X), comprise tapered end and lock core, be provided with lock core hole in the tapered end, lock core is inserted in the lock core hole rotationally, lock core inside is axially arranged with keyhole along it, the edge is provided with some container cavities perpendicular to the lock core axial direction in lock core, be provided with mobilizable blade in the container cavity, container cavity communicates with keyhole, the lock core hole inwall be provided with for blade on the set convex body draw-in groove of clamping mutually, described keyhole is the open slot that is formed on the lock core, and the aperture position of this open slot is positioned on the outer peripheral face of lock core.Keyhole in the lock core in this tapered end is convenient to processing and machining accuracy height.

Blade in this tapered end becomes single and occurs, and its anti-technical unlocking performance is relatively poor relatively.

Summary of the invention

For overcoming above-mentioned defective, the utility model technical issues that need to address are: a kind of multidimensional vane type tapered end is provided, and the anti-technical unlocking performance of this tapered end is good.

For solveing the technical problem, the technical solution of the utility model: a kind of multidimensional vane type tapered end, the lock pipe that comprises hollow, be provided with lock core rotationally in the lock pipe, the edge is provided with some penetrating open-works that are used for the assembling blade perpendicular to axis direction in lock core, inner peripheral surface at the lock pipe is provided with draw-in groove, be provided with keyhole in the lock core, it is characterized in that: in each open-work, all be provided with two blades versatilely, be equipped with outstanding little convex body on the blade towards the both ends of open-work oral area, little convex body is used for being connected in the draw-in groove, is provided with a little spring corresponding to a slice blade in lock core, and the elastic force of two suffered springs of blade in open-work is opposite; Blade is provided with the ridge that extend in the keyhole.After in keyhole, inserting key, ridge on chute on the key or the Qu Bianyu blade contacts, position or the size of ridge on the different open-work intra vanes on blade separately generally has difference, chute on the key or the trend on bent limit are corresponding with these difference, after the key insertion puts in place, and make the position of blade in lock core be in not stop that on the state that lock core rotates, namely the little convex body on the blade is thrown off mutually with the draw-in groove on the lock pipe inner peripheral surface in lock tube.If transfer to key, under the effect of little spring, the little convex body on the blade reaches the outside of open-work oral area, and these little convex bodys can be connected in the draw-in groove and limit lock core rotation in the lock pipe.

Described blade is equipped with two little convex bodys that arrange at interval towards the both ends of open-work oral area, described draw-in groove is four.

Described blade is provided with through hole, and described ridge is positioned at through hole.

Described ridge is dihedral.

Be provided with some spring eyes that communicate with open-work in lock core, spring eye is parallel with open-work.

The beneficial effects of the utility model are: because two blades all are set in each open-work in tapered end, and the direction that these two blades are subjected to spring force is opposite, when realizing that tapered end carried out technical unlocking, need stir to both sides respectively two blades in the same open-work, and the space of keyhole itself is limited, open-work is a plurality of in addition, and this has increased the tapered end difficulty of technical opening, thereby can effectively improve the anti-technical unlocking effect of tapered end.The multidimensional blade is that the two ends that are embodied in blade are provided with little convex body, even the same end of blade arranges a plurality of little convex bodys.Adopt multidimensional blade construction form, the structure of two blades in the same open-work can be identical, and just opposite on assembly direction, the otherness that this has reduced lock core intra vane structure has made things convenient for the assembling to blade.

The specific embodiment

See among the figure that the structure of the utility model multidimensional vane type tapered end comprises the lock pipe 4 of hollow, be provided with lock core 1 rotationally in the lock pipe 4, be axially arranged with keyhole 6 along it in the lock core 1.Except several pellets shot from a slingshot are set, also be provided with some blades 5 in the lock core 1.Specifically be, be provided with some penetrating open-works 2 in lock core 1, these open-works 2 are perpendicular to lock core 1 axis.Be equipped with blade 5 in the open-work 2 movably, in lock core 1, be provided with the little spring 7 that acts on the blade 5, under the effect of little spring 7 elastic force, the extended outside to open-work 2 oral areas, the end of blade 5, the set little convex body 13 in blade 5 ends can be connected in the draw-in groove 9 set on lock pipe 4 inner peripheral surfaces, and draw-in groove 9 extends axially along lock core 1.Be equipped with the ridge 8 that can extend in the keyhole 6 on the every blade 5, these ridges 8 are used for and the chute or the bent limit that are inserted on keyhole 6 keys 10 contact.
