Description

Lock core pick-proof lid
Technical field
The utility model belongs to the lockset accessory, is specifically related to a kind of lock core pick-proof lid.
Background technology
Mortise door lock is one of main lockset of security door use.In order to prevent that the thief from opening the door and steal by destroying lock core, lock core pick-proof lid is installed in addition in the outside of door leaf usually the end of lock core is covered.Existing lock core pick-proof lid as shown in Figure 1 and Figure 2, comprise and be enclosed within on the lock core 6 and be fixed on base plate 1 on the door skin A, be fixed on the cap 2 on the base plate 1, cap 2 is provided with rotary anti-drilling rotatable lamella 3, rotatable lamella 3 is provided with the perforate 301 corresponding with keyhole on the lock core 6, is provided with the fixedly interior cover 4 of rotatable lamella 3 in the cap 2.Existing lock core pick-proof covers the problem that exists, and the one, cap 2 is connected with base plate 1 by rivet 5, and a step is arranged between the bottom of cap 2 and the base plate 1, is easy to utilize this step that cap 2 sleds are fallen with instrument, reaches the purpose of destroying lock core; The 2nd, the perforate 301 that can use the high strength instrument to insert rotatable lamella 3 with rotatable lamella 3 spreadings, continues to insert the keyhole of lock core 6 again with lock core 6 destructions.
The utility model content
The purpose of this utility model provides a kind of ruined lock core pick-proof lid that is difficult to.
The technical scheme that realizes above-mentioned utility model order employing is as follows:
The lock core pick-proof lid that the utility model provides, comprise and be enclosed within on the lock core and be fixed on base plate on the door skin, be fixed on the base plate and the cap lock core end anastomosis, cap is provided with rotary anti-drilling rotatable lamella, and anti-drilling rotatable lamella is provided with the perforate corresponding with keyhole on the lock core; Described base plate is provided with depressed part, and match with depressed part on the described base plate in the bottom of described cap, and the flush of the surface of the bottom of cap and described base plate, connects by screw between the bottom of cap and the base plate.
Further technical scheme is that the back that is positioned at described anti-drilling rotatable lamella in the described cap has additional another described anti-drilling rotatable lamella.
Lock core pick-proof lid of the present utility model, owing to match with the depressed part on the base plate in the bottom of cap, and the surface of the bottom of cap and the flush of described base plate make the bottom of cap and base plate not have step, can't utilize this step that cap is prized with instrument.Have additional another anti-drilling rotatable lamella owing in cap, be positioned at the back of described anti-drilling rotatable lamella again, increased the difficulty of opposing instrument by keyhole destruction lock core.Therefore, lock core pick-proof lid of the present utility model is strengthened greatly than the tamper-resistant function of prior art, and the lock core safety of being furnished with the utility model lock core pick-proof lid also is greatly improved.
Below in conjunction with accompanying drawing the technical solution of the utility model is described further.
