Technical Field

The invention relates to articles for daily use, in particular to an inner core of a lock and an unlocking tool.

Background

WO 2008/034345 Al as prior art discloses a blade-twistable 360-degree anti-theft lock and an unlocking key, the anti-theft lock comprises a housing, a lock cylinder, a spring, a pin tumbler, a bushing, a locking catch key, unlocking blades and spacing blades, the unlocking blades are movably arranged in the lock cylinder at certain intervals, each unlocking blade is provided with an unlocking groove and a key hole, and the inner wall of the key hole is provided with a protrusion which can be matched with a tooth socket on the key. Under the unlocking state, the bulges in the key hole of each unlocking blade are arranged in a staggered way at a certain angle. The key body of the unlocking key is a cylinder with tooth grooves, and the tooth grooves are distributed in a curve section way around the circumferential surface of the key body. Wherein, the unlocking blade of the anti-theft lock head can be freely twisted. Because the blade of unblanking can freely twist reverse, all archs can distribute on whole circumference, and the lock core is after being inserted or the technique is unblanked by other keys, and the protruding rotation that probably appears blocks on the route of unblanking key insertion, leads to unblanking key unable smooth and easy to insert and influences the user and unblank normally.

Disclosure of Invention

The invention aims to provide an inner core of a lock, which is convenient for users to use normally on the premise of not reducing the safety.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides an inner core of lock, including core and blade, the core is equipped with the mounting groove that supplies unlocking means male eyelet and be used for installing the blade, the mounting groove communicates with the eyelet is crossing, the blade can be followed core circumference rotation in the mounting groove, the blade is equipped with the jack that supplies unlocking means to alternate, with unlocking means complex unblank protruding and be used for holding the recess of unblanking of lockpin, all jacks and eyelet axial alignment, unlocking means inserts and targets in place and makes all recesses axial alignments of unblanking, the lockpin falls into and unblanks the core in the recess of unblanking, be equipped with the spacing face that the rotation angle alpha that is used for restricting the blade in the mounting.

Furthermore, the limiting surface comprises a first limiting surface with two opposite surfaces arranged in parallel, and the blade is provided with a first matching surface used for abutting against and limiting the first limiting surface.

Furthermore, the limiting surfaces comprise two second limiting surfaces, and the blade is provided with a second matching surface used for abutting against and limiting the second limiting surfaces.

Further, the mounting groove penetrates to the outer peripheral side surface of the core, and the blade is inserted into the mounting groove from the outer peripheral side surface of the core.

Furthermore, the projection of the mounting groove on the cross section of the core body is in a T shape.

Furthermore, the inner wall of the jack is provided with a guide cambered surface, and the guide cambered surface rotates along with the unlocking tool after the unlocking tool is inserted into the jack.

Furthermore, the hole wall of the eyelet is provided with a guide groove for facilitating the insertion of an unlocking tool, and the guide groove is avoided by the rotation range of the unlocking protrusion.

After the technical scheme is adopted, the invention has the following advantages: firstly, the rotation angle alpha of the blade is not more than 180 degrees, the unlocking protrusion can only rotate in a half-cycle range at most along with the blade, and tooth sockets on the unlocking tool are generally arranged on a single surface or double surfaces, so that the unlocking protrusion of all the blades can only rotate on one side of the unlocking tool corresponding to one tooth socket, after the core body is inserted by other keys or unlocked by technology, the unlocking protrusion is still distributed on one side of the unlocking tool, and after a user inserts the unlocking tool into the inner core, the unlocking protrusion cannot be blocked on a path in which the unlocking tool is inserted, so that the unlocking tool is very convenient to use; secondly, the rotation angle alpha of blade is no more than 180, and the quantity of blade generally sets up more than 6, and the bellied rotation range of unblanking diminishes, looks up from the axial of core, and the arch of unblanking of keeping away from the eyelet entry can be blockked by the arch of unblanking that is close to the eyelet entry easily, and the inner core is when unblanking by the technique, and the person of unblanking is difficult to carry out the direct operation to the arch of unblanking of keeping away from the eyelet entry, greatly increased the degree of difficulty that the inner core was unblanked by the technique to the security of tool.

The invention also provides an unlocking tool which is used for unlocking the inner core of the lock and comprises a rod body, wherein the rod body is provided with flaring tooth sockets, two opposite side walls in the tooth sockets are provided with driving surfaces, the driving surfaces are inclined relative to the bottom surfaces of the tooth sockets, and the driving surfaces contact the unlocking bulges to enable the blades to rotate.

Furthermore, the entry of alveolus is loudspeaker form, and all the unblanking protrusions that this alveolus corresponds the drive all are located the movement track of alveolus entry.

After the technical scheme is adopted, the invention has the following advantages: because the axial of unlocking means along the core inserts the eyelet, and the blade is around unlocking means and make rotary motion, consequently set up the driving surface of slope and can be smoothly convert axial effort to circumference effort, make the blade rotatory smooth and easy, experience when the user inserts unlocking means is better.
