Abstract
The utility model relates to a spring lock with two rows of springs. The utility model is characterized in that two rows of radial spring holes of a lock core are symmetrically arranged at the axial center line of the lock core, the central axis line of each spring hole is arranged on the axial plane of the same center of the lock core, two rows of spring holes on a lock head are separately and correspondingly matched with two rows of spring holes on the lock core, and the middle part of a double-surface teeth key which is matched with the spring lock is provided with a longitudinal positioning slot. The utility model has the advantages of reasonable structure, high cipher-key quantity, convenient operation and good theft-proof and confidential performance.
Description
The utility model belongs to lock technology field.
Cylinder lock commonly used at present is single-row billiard tapered end and single cog key, because the restriction of tapered end length, pellet shot from a slingshot hole and marble amount just are restricted, thereby affect the further raising of the antitheft security performance of cylinder lock.The patent No. is the patent of CN87200441, has proposed the design of " two sides teeth key and double cylinder lock ", has so just increased the pellet shot from a slingshot hole of cylinder lock exponentially, thereby has improved the secret key amount of cylinder lock greatly, has improved the secrecy of cylinder lock.
But this design structurally remains in some shortcomings, for example: its double cog key cross section one-tenth "
" shape, the spoon face does not have locating slot, opens and uses inconvenience, and the lock core center line is all departed from the double pellet shot from a slingshot hole of lock core, causes pellet shot from a slingshot hole processing difficulties, and tolerance is big, is prone to the unlatching resistance and rolls phenomenon, and the straight door span of lock core is big, is unfavorable for antitheft.
It is big that the purpose of this utility model provides a kind of secret key amount, and double pellet shot from a slingshot hole is provided with rationally, open easy to use, the double ball lock head and the key thereof that maintain secrecy, theftproof performance are good.
The technical solution that realizes above-mentioned purpose is: offer two and arrange radially pellet shot from a slingshot hole on lock core, and make two to arrange the longitudinal center line that pellet shot from a slingshot hole radially is symmetrical in lock core, the central axis in each pellet shot from a slingshot hole is positioned on the same center axial plane of lock core; Offer two row's pellet shot from a slingshot holes on the tapered end equally, with corresponding the coincideing in two row's pellet shot from a slingshot holes of lock core; The set denticle in key both sides matches with two pellets shot from a slingshot of arranging in the pellet shot from a slingshot holes of lock core respectively, and the key middle part is provided with the locating slot of being convenient to open guidance.
Accompanying drawing 1 is a general structure schematic diagram of the present utility model.
Accompanying drawing 2 is a tapered end, two row's pellet shot from a slingshot hole layout view of lock core.
Accompanying drawing 3 is a double cog Key structure schematic diagram.
The utility model is elaborated with embodiment below in conjunction with accompanying drawing.
Offer two row pellet shot from a slingshot holes (3) respectively in the radially both sides of lock core (1) and tapered end (2), every row establishes 4 holes, and two rows are totally 8 holes.The central axis in each pellet shot from a slingshot hole (3) all is positioned on the same center axial plane of lock core and tapered end, the machining that helps the pellet shot from a slingshot hole like this, help improving the quality of fit of pellet shot from a slingshot hole and pellet shot from a slingshot, avoid producing opening to hinder and roll phenomenon, when helping lock core (1) simultaneously and packing tapered end (2) into, corresponding the coincideing in its two rows pellet shot from a slingshot hole.The difference setting-in also is equipped with spring (4) by the different differential pellet shot from a slingshot (5) of certain collocation in each pellet shot from a slingshot hole in the tapered end pellet shot from a slingshot hole.6 grades of pellet shot from a slingshot in the present embodiment (5) employings are differential, and the different key bit amounts of cylinder lock can reach 6 like this
8, and effectively the secret key amount substantially exceeds the secret key amount standard of national regulation more than 120,000.Be provided with longitudinal register groove (7) in the double cog key (6), its both sides denticle (8) matches with two pellets shot from a slingshot of arranging in the pellet shot from a slingshot holes (5) of lock core (1) respectively, the cross section one-tenth of key body "
" shape, this structure makes the straight door span of lock core key slotted eye corresponding with it less, helps preventing that the sled to lock from dialling destruction.
The utility model is rational in infrastructure, and secret key amount height is opened easy to usely, and antitheft security performance is good.
Claims (1)
1, a kind of cylinder lock with double pellet shot from a slingshot, comprise the lock core (1) and tapered end (2) that are provided with double pellet shot from a slingshot hole, and the key that matches (6), it is characterized in that the double radially pellet shot from a slingshot hole of lock core (1) is symmetrical in the longitudinal center line of lock core (1), and the central axis in each pellet shot from a slingshot hole is positioned on the same center axial plane of lock core (1), on the tapered end (2) two row pellet shot from a slingshot hole is corresponding identical with two row's pellet shot from a slingshot holes on the lock core (1) respectively, arrange the double cog key (6) that the pellet shot from a slingshot (5) in the pellet shot from a slingshot holes matches with two of lock core (1), its middle part is provided with longitudinal register groove (7).
