Abstract
The utility model provides a double locked spring lock which is characterized in that the utility model comprises a mechanical locked part and a magnetic locked part; the mechanical locked part is provided with an anti-theft false slot at the middle part of at least more than one spring in the lock, and the structure of the anti-theft false slot is the same as the structure of an annular groove used for unlocking the lock; a position approaching to the inner end surface of a lock body is provided with a magnetic lock position; a corresponding magnetic grain is arranged on a key. The utility model has the advantages that the theft degree is very difficult, and the utility model has the advantages of a mechanical lock and a magnetic lock. The utility model is a good anti-theft lock body.
Description
Technical field: the utility model relates to cylinder lock, particularly a kind of cylinder lock of double locking.
Background technology: existing cylinder lock has mechanical caging, and also having is magnetic lock by the magnetic locking." a kind of high anti-theft billiards tapered end " applied on December 22nd, 2002 as me of mechanical caging, its application number is: 200320123260.5; Magnetic locking as " a kind of magnetic cylinder lock ", its patent No. is " 00257628.7 ".Higher theftproof should be said or have to these two kinds of locks, in any case but, they still have certain defective, thus the mechanical instruments of being seen clearly in the lock by the people easily such as the available master key of locking mechanism, probe are opened lock.Magnetic lock then can overcome this defective of mechanical lock, and the locking mechanism in the lock is stashed, and makes the people can't see its interior structure, thereby is difficult to open with the instrument free call on sb. else's expense through illegal means.But also there is certain weakness in magnetic lock, when promptly the permanent magnet in locking meets high temperature, thereby is easy to take place the demagnetization phenomenon and loses magnetism lock body was lost efficacy.The people of pirate of the open lock can utilize this weakness of magnetic lock fully and easily lock be opened.
Summary of the invention: the purpose of this utility model is at above-mentioned two types lock, existing deficiency, and the cylinder lock that proposes a kind of comprehensively both advantages and complement one another and carry out double locking.
Can realize the purpose of this utility model by following technical proposals, a kind of cylinder lock of double locking, comprise key, lock body, the lock core and the locking that are located in the lock body are provided with, it is characterized in that: also be included in pellet shot from a slingshot at least one the above intermediate portion position of locking in being provided with except the annular groove that is provided with the usefulness of unblanking, also be provided with the antitheft false groove identical with this circular groove structure, be provided with a hole at the nearly inner face of lock body place and be built-in with a spring and irony pellet shot from a slingshot, match with this irony pellet shot from a slingshot, be provided with hole in the corresponding position of lock core and be built-in with the magnet that can move radially in the hole, fit over mutually with this magnet and to be furnished with corresponding magnetic grain on the key, the polarity that the magnetic grain is relative with magnet is identical.Locking also is provided with one in being provided with makes locking side column slide to the oblique mechanism of annular groove when making bias force mechanism that locking side column slides to latch recess and a rotational lock core, and its annular groove sidewall is straight, and with the locking side column plane parallel.
Effect of the present utility model is, very high theftproof is arranged, one has been established plural antitheft false groove on pellet shot from a slingshot, make theft pirate of the open lock body increase very big difficulty, its two hidden magnetic lock-bit setting is provided with defence line, second road for pirate of the open again, it three also has certain improvement on locking is provided with, these make this lock have higher theftproof performance than general theftproof lock.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings:
Accompanying drawing 1 is the utility model vertical structure sectional view;
Accompanying drawing 2 is the vertical structure sectional view of the utility model after rotating 90 ℃ on Fig. 1 basis;
Accompanying drawing 3 is mechanical locking part opening schematic diagram (laterally analysing and observe) in the utility model;
Accompanying drawing 4 is magnetic lock certain portions opening schematic diagram (vertically analysing and observe) in the utility model.
The specific embodiment: referring to accompanying drawing 1,2,3,4, in lock body 1, be provided with lock core 2, lock core 2 cylinders are provided with gathering sill vertically, space between it and lock body 1 inwall constitutes key hole, the gathering sill center distributes vertically the pellet shot from a slingshot hole of being made up of blind hole 3 is set, pellet shot from a slingshot hole 3 is vertical with gathering sill, inserting spring and pellet shot from a slingshot 5 successively in the pellet shot from a slingshot hole 3, pellet shot from a slingshot 5 surperficial middle parts are provided with annular groove 7, its cross section is " U " shape, recess sidewall is straight and with locking side column 8 plane parallel, latch recess 6 cross sectional shapes can " Λ " type, also be provided with antitheft false groove 14 on the surface of pellet shot from a slingshot 5, it is identical with annular groove 7 structures, the line of rabbet joint 4 is being set the position of 90 ℃ of phasic differences mutually with pellet shot from a slingshot hole 3 row, it slightly is longer than pellet shot from a slingshot hole row and communicates with it, lock body 1 inwall and the line of rabbet joint 4 correspondence positions are provided with arcuate bottom half slot formation latch recess 6 during locking states, the locking side column 8 of sheet is slidably disposed between the line of rabbet joint 4 and the latch recess 6, the line of rabbet joint 4 both end sides also respectively are provided with a back-moving spring storage chamber 10, it is built-in with back-moving spring 11, sheet locking side column 8 two ends are provided with horizontal lug 81, back-moving spring 11 is against lug 81 downsides and constitutes bias force mechanism, also be provided with two ball storage chambeies 12 at the line of rabbet joint 4 outer ledges, locking side column 8 correspondence positions are provided with complementary notch 13, ball 9 is inserted in the ball storage chamber 12 rotationally, ball 9 diameters and the latch recess 6 formation oblique mechanism that matches.On lock body 1, be provided with radially hole, built-in spring 19 and irony pellet shot from a slingshot 15, correspondingly with irony pellet shot from a slingshot 15 be provided with hole on lock core 2 it is built-in with the magnet 16 that can move radially, be provided with the magnetic grain 18 corresponding with magnet 16 on key 17, the polarity of their opposite ends is identical, promptly can be N, N or S, the S utmost point, when key 17 inserted, 18 pairs of magnets 16 of magnetic grain had a repulsive force, and it promotes irony pellet shot from a slingshot 15 and moves and holddown spring 14, irony pellet shot from a slingshot 15 breaks away from lock core 2, lock body breakdown.
