Abstract

The utility model discloses a change pellet shot from a slingshot lock core structure and private key thereof, it is including fixed solid lock spool, by in proper order with coaxial mode suit at the fixed epaxial key hole layer of solid lock, change and lock core shell outside interior, offered one to two helicla flute on the interior pore wall on key hole layer radially set up the pellet shot from a slingshot hole at the bottom of a plurality of helicla flutes that pass lock core shell, change and key hole layer in proper order on the lock core shell, downthehole tip pellet shot from a slingshot, middle pellet shot from a slingshot and the compression spring of having loaded in proper order of pellet shot from a slingshot, the tip end top of tip pellet shot from a slingshot is on the outer disc of fixed solid lock axle, compression spring is located the outer end of lock core shell and passes through the sprue encapsulation, the one end end wall that is located the lock body of change is connected with the spring bolt driving medium that is used for opening the spring bolt.

Description

A kind of change lock cylinder structure and private key thereof

Technical field

The utility model relates to and belongs to theftproof lock technical field, relates to a kind of change lock cylinder structure and private key thereof specifically.

Background technology

Along with technology development and the raising of technical opening cylinder lock, the theftproof performance of current cylinder lock does not but have raising, reason is since cylinder lock comes out, its agent structure: lock body shell+rotatable lock core+key=cylinder lock, over more than 160 year, never change, the intrinsic defect of this structure never fundamentally solves.Such as: pellet number very little, pellet is easily touched by foreign matter, key-type system too simply can be joined whenever and wherever possible, secret key amount is easily opened very little mutually, other type lock (light-operated, automatically controlled, magnetic control lock) that some protection level are high, performance is not very reliable (optical, electrical, magnetic can invisible disappearance), and expensive, instream factor is not high.Use on the market at most at present, the widest or cylinder lock, but its antitheft effect and not good.

Summary of the invention

The purpose of this utility model just in order to solve the problem existing for above-mentioned prior art, and provides a kind of change lock cylinder structure and the private key thereof that effectively can improve anti-theft function of cylinder lock ability.

The utility model realizes the technical scheme that above-mentioned purpose takes: a kind of change lock cylinder structure, and it comprises fixing solid lock shaft, by the key aperture layer be sleeved in coaxial mode successively outside interior on fixing solid lock shaft, change and lock core shell; The inner hole wall of described key aperture layer offers one to two helicla flute, on described lock core shell radial offer multiple successively through the marble hole at the bottom of helicla flute of lock core shell, change and key aperture layer, tip pellet, middle pellet and Compress Spring is filled with successively in described marble hole, the tip end of described tip pellet withstands on the periphery of fixing solid lock shaft, the outer end that described Compress Spring is positioned at lock core shell is encapsulated by sprue, and one end end wall being positioned at lock body of described change is connected with the dead bolt driving member for unlock deadbolt.

A kind of private key for opening described lock core structure, it comprises key bit that match with the helicla flute of key aperture layer, spiral tabular, the rear end of described key bit is fixed on the contiguous block of middle part in coaxial mode, and the outer end of described middle part contiguous block is connected with rotary handle; The periphery of described key bit is provided with the bullet groove matched with tip pellet when time in the helicla flute that key bit screws in key aperture layer completely, and the degree of depth of described bullet groove can make when corresponding tip pellet the short top of tip to tip pellet during bullet groove bottom land and middle pellet contact surface just in time with the contact surface coplanar of change and key aperture layer.

Use principle of the present utility model and beneficial effect as follows: fixing solid change lock core of the present utility model, general marble hole number can be 30-50, because lock core shell Area comparison is large, on it, the size and shape of marble hole can be different, the best arrangement mode of marble hole is radial lack of alignment, also can non-static fields lack of alignment (any direction).Marble hole direction is any, and number is many again, and size, shape can be different, again can the feature of lack of alignment, determines this kind of cylinder lock secret key amount inevitable very huge, greatly to being difficult to the imagination; The Compress Spring of pellet is arranged in lock body shell, and tip pellet (one end point one is held level with both hands) is arranged on by fixing solid lock shaft one end, and middle pellet is arranged on centre.When not inserting key, middle pellet to be advanced in change one section, so be just seized the rotation of change by Compress Spring; When inserting correct key, thickness bottom bullet groove corresponding is on the key compressed into middle pellet by tip pellet again in lock body shell, the thickness at the bottom of bullet groove corresponding on the key adds the length of tip pellet, when just equaling the degree of depth of pellet hole between change outer wall and fixing solid lock shaft outer wall, the tack of tip pellet is just positioned at the critical borderline of change and lock body shell, when the butt end of all tip pellets is positioned on this critical borderline, change just can have rotated, and then drives dead bolt driving member just lock can be opened; Certainly, can by the length of tip pellet from being made with long or unequal length, the degree of depth of bullet groove so on the key also can be identical or different; Helicla flute can be single-screw or double helix; The utility model replaces the keyhole of common spring lock by helicla flute, thus the marble amount that can arrange is increased, even if make stealer use the unlocking tools such as existing iron wire to be difficult to open when not knowing other specification data such as spiral fluted pitch, be equally also difficult to configure dedicated key; Thus the anti-theft capability of the utility model lock core is increased substantially; The utility model change lock core structure is simple, and anti-technical opening performance is very good.
