Description
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, defending people's the security of the lives and property, safeguarding the stable purpose of society, nowadays, lockset has formed a very huge family, 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 in the market, in fact do not possess real anti-theft feature, 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, as the common door built-in lock, Door lock, cross door built-in lock etc., though their pattern, structure, big or small inequality, the principle of unblanking is identical.As the saying goes: " ten thousand become not 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 to be solved in the present invention 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 is achieved through the following technical solutions:
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, described lock core base body is provided with locking groove near key one end, be 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 described lock core hole, lock core shaft's one end is fixedlyed 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: described 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 mutually with the B locking groove; Be respectively arranged with A braking roll, B braking roll in A locking groove, the B locking groove, A braking roll, B braking roll are connected with the lock core base body by the interior spring that is provided with of A locking groove and B locking groove two-phase far-end respectively; Described 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:
Described 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 by being provided with on pin and the lock core base body; Be symmetrically arranged with the stop bayonet socket on the pin of described 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 described stop bayonet socket.
The present invention compared with prior art has following obvious advantage:
The present invention adopt " key is directly inserted key; the knob that is provided with on the rotation lock mandrel then; thus shrink dead bolt; open mechanical lock " the mode of unblanking, the lock core that has solved conventional lock is for circular, 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.
