Abstract
The utility model discloses a protective lid for lock core, which is installed on the end faces of the cores of various built-in locks, comprising a protective scute and an inner baffle. The utility model is characterized in that a hole for mounting screw is arranged on the protective scute whose step hole has enough space to make the inner baffle rotate by 360 DEG freely. The utility model is suitable for matching with various existing built-in locks and drawer locks, the mechanical strength and the rotation of the inner baffle along the drilling direction are used for preventing the drilling, the impinging, and other manners from destroying the lock cores. The protective lid has the advantages of simple production and installation, low cost, and strong reliability.
Description
The utility model relates to a kind of lock core protective cover that protects scuta and interior plate washer composition, especially is installed in the lock core protective cover of various built-in lock core end faces.
Prevent that destroying lock core with the drilling mode is technology anxious to be developed, China's utility application discloses " a kind of protection type built-in lock " 902137212, the major technique characteristics are to install the protection scuta additional at the lock core end face, and inactive interior plate washer is housed in the stepped hole of protection scuta.The safeguard procedures of this patent application have certain effect, have weak point simultaneously: the protection scuta can only be sleeved on lock core end face annulus to be had on the built-in lock of special screw thread, and need to use cementing agent to fix, this not only makes lockmaking technology increase, install and change trouble, and promotes the use of and be greatly limited; The protection scuta tightly fastens interior plate washer, and interior plate washer can not rotate freely, and is difficult to effectively prevent the destruction of electric drill to lock core.
The purpose of this utility model is: a kind of lock core protective cover is provided, is fit to the existing various door built-in locks of adapted, drawer-lock, improve the lock core barrier propterty, particularly prevent the ability of drilling.
Goal of the invention of the present utility model is achieved like this: the lock core protective cover is made up of protection scuta and interior plate washer, on the protection scuta circular hole is arranged respectively, the plate washer hole, the lock core end-face hole forms continuous stepped hole, interior plate washer is circular, have the strip keyhole, it is characterized in that, the medial surface of protection scuta has screw hole, the diameter of interior plate washer is less than the diameter of baffle holes, Internal baffle thickness is less than the degree of depth of baffle holes, Internal baffle is contained in the baffle holes position on the protection scuta, before lock core protected cover screw and door combines the lock core end face that is fixedly mounted on built-in lock, Internal baffle can rotate freely by 360 degree.
The utility model has the advantages that: be provided with installation on the scuta in protection and make its mounting means radical change after with screw hole, all can be used from installing expand as on various existing door built-in lock drawer-locks at special built-in lock originally; The diameter of Internal baffle is less than the diameter of baffle holes, its thickness is less than the degree of depth of baffle holes, this structure can rotate freely baffle-plate-sleeve in Internal baffle hole and space that lock core end face capitiform becomes, the Internal baffle that hardness can reach RC40 is suffering the electric drill drilling not only to be difficult to bore bad, and Internal baffle more makes electric drill not play a role along with the rotation of electric drill rotation direction.The lock core protective cover can also effectively prevent with otherwise damage built-in locks such as impaction lock cores.The manufacturing of lock core protective cover, install all very easy.Protection is reliable, and cost of production is low, and it is very big to promote the use of potentiality.
Below in conjunction with accompanying drawing embodiment of the present utility model is further specified:
Fig. 1 protects the scuta sectional drawing
Fig. 2 Internal baffle side view
Fig. 3 Internal baffle front view
Fig. 4 lock core protective cover installation drawing (on steel casement door, installing) with F5-4 door built-in lock adapted
As seen from the figure, commercially available F4-5 security door built-in lock (9) welding is contained on the outer steel sheet (12) of steel protective door, and dead bolt (10) and dead bolt button (11) are in conjunction with shape.The lock core end face has been installed the lock core protective cover on (8); comprise in the lock core end-face hole (2) on the protection scuta (1) and be inserted in lock core end face (8); be inserted in Internal baffle (6) in the baffle holes (3) on the protection scuta (1); the utility model defines the real space that space that Internal baffle (6) occupies is not more than corresponding formation; if use electric drill by circular hole (4); when aiming at bar shaped keyhole (7) brill lock core; Internal baffle (6) is spent equidirectional rotation with brill; countervaling power; hardness reaches RC40 after Internal baffle being quenched in addition, has very protected lock core reliably.Shown among the figure that protection scuta (1) screws in screw hole (5) by three screws (13) and fixes.Except anti-drilling, the lock core protective cover has also obviously increased by one pair of armor to built-in lock, makes crashproof, pick-proof ability raising, can realize goal of the invention.The utility model is selected metal material for use, pass through the coating Quenching Treatment respectively, implementation process is comparatively easy, standard size according to door lock, drawer-lock, by produced in series, extensively be suitable for the built-in lock protection of various metals, nonmetal door or drawer, for attractive in appearance, also can be made into various kinds abnormity pattern, as square, prismatic, animals shaped etc.
