Description

The direct insertion anti-theft lock of a kind of key

Technical field

The present invention relates to mechanical lock, be specifically related to the direct insertion anti-theft lock of a kind of key.

Background technology

Lockset is being brought into play the function of " taking into custody constraint " in human civilization society; Standard social action, is defending people's the security of the lives and property, is safeguarding the stable purpose of society; Nowadays at present; Lockset has formed a family that ten minutes is huge, and is constantly improving and update, and constantly develops to our needed directions such as " pick-proof, anti-drilling, shockproof, anti-saws ".

The mechanical lock of many types does not in fact possess real anti-theft feature in the market, in face of the higher stealer of technology; Two steel wires or several simple tools just can be opened these locks; Not because they have consummate technology and special unlocking tool, but because the lock core know-why and the structure of conventional lock are too single, simple, like the common door built-in lock; Door lock; Cross door built-in locks etc., though their pattern, structure, size are inequality, the principle of unblanking is identical.As the saying goes: " ten thousand become from wherein " why identical these locks principle of unblanking is, and the lock core that mainly is them is a circular object, and the person of unblanking adopts the mode of " looking for pellet shot from a slingshot ", and by getting rid of a pellet shot from a slingshot, rotary locking cylinder slowly can be opened lockset simultaneously.The people who learned physics knows to have only circular object freely to rotate, and object square, flat can not arbitrarily rotate.

Summary of the invention

The technical problem that the present invention will solve provides the direct insertion anti-theft lock of a kind of key, and lock core know-why, the frame for movement that this technical scheme has solved conventional lock is single, the problem of anti-theft feature difference.

The present invention realizes through following technical scheme:

The direct insertion anti-theft lock of a kind of key; Comprise the lock core base body that is provided with key, pellet shot from a slingshot hole, pellet shot from a slingshot, said lock core base body is provided with locking groove near key one end, is provided with braking roll in the locking groove; The opposite end is provided with lock core hole; Be provided with lock core shaft in the said lock core hole, lock core shaft's one end is fixedly connected with knob, and its opposite end is connected with dead bolt; The lock core base body is provided with the lock core cover, and during locked state, the stop bayonet socket that lock core puts blocks braking roll, and lock core cover inner face and lock core shaft's one side fit.

The further Technological improvement plan of the present invention is:

The direct insertion anti-theft lock of a kind of key according to claim 1; It is characterized in that: said locking groove comprises A locking groove, B locking groove; A locking groove, B locking groove are vertically " in-line " setting, and the A locking groove is connected with the pellet shot from a slingshot hole in the near-end with the B locking groove mutually; Be respectively arranged with A braking roll, B braking roll in A locking groove, the B locking groove, A braking roll, B braking roll respectively through A locking groove and B locking groove two mutually in the far-end spring of setting be connected with the lock core base body; Said lock core shaft two links are cylinder, and the cross section of mid portion is projected as semicircle or for rectangle or for prismatic, and to have a side at least be the plane.

The further Technological improvement plan of the present invention is:

Said lock core base body is symmetrically arranged with slot on the upper and lower end face, and the lock core cover is symmetrically arranged with pin on the upper and lower end face, and distance is greater than lock core shaft's Breadth Maximum between symmetrically arranged pin, and pin group number and groups of slots number are complementary; The slot coupling clamping of lock core cover through being provided with on pin and the lock core base body; Be symmetrically arranged with the stop bayonet socket on the pin of said lock core cover.

The further Technological improvement plan of the present invention is:

The wide braking roll diameter that is slightly larger than of the card of said stop bayonet socket.

The present invention compared with prior art has following obvious advantage:

The present invention adopts the mode of unblanking of " key directly being inserted key, the knob that is provided with on the rotary locking cylinder axle then, thereby contraction dead bolt; open mechanical lock ", and the lock core that has solved conventional lock is for circular, and the person of unblanking utilizes " looking for pellet shot from a slingshot " mode; By an eliminating pellet shot from a slingshot; While is rotary locking cylinder slowly, can open the lockset problem, for we provide a kind of mechanical mechanism more reasonable, compact, safe mechanical lock core.
