Abstract
The invention discloses a kind of lock core prizing-proof cover, including the base plate being enclosed within lock core and being fixed on door skin, the cap with lock core end anastomosis that is fixed on base plate, cap is provided with rotary anti-drilling rotatable lamella, anti-drilling rotatable lamella is provided with the perforate corresponding with the keyhole on lock core, described base plate is provided with depressed part, match with the depressed part on described base plate in the bottom of described cap, and the surface of the bottom of cap flushes with the surface of described cap.The lock core prizing-proof cover more existing lock core prizing-proof cover tamper-resistant function of the present invention is greatly reinforced, and the lock core safety being furnished with lock core prizing-proof cover of the present invention is also greatly improved.
Description
Technical field
The invention belongs to lockset accessory, be specifically related to a kind of lock core prizing-proof cover.
Background technology
Mortise door lock is one of main lockset of antitheft door use.In order to prevent thief from stealing by destroying lock core enabling, generally at the outside of door leaf additionally mounted lock core prizing-proof cover, the end of lock core is covered.Existing lock core prizing-proof cover is as shown in Figure 1 and Figure 2, including the base plate 1 being enclosed within lock core 6 and being fixed on door skin A, the cap 2 being fixed on 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 the keyhole on lock core 6, is provided with the inner sleeve 4 of fixing rotatable lamella 3 in cap 2.Existing lock core prizing-proof cover there is problems of, and one is that cap 2 is connected with base plate 1 by rivet 5, has a step between bottom and the base plate 1 of cap 2, it is easy to utilizes this step to be fallen by cap 2 sled with instrument, reaches to destroy the purpose of lock core；Two is the perforate 301 that high intensity instrument can be used to insert rotatable lamella 3, and by rotatable lamella 3 spreading, lock core 6 is destroyed by the keyhole being further continued for inserting lock core 6.
Summary of the invention
It is an object of the invention to provide a kind of lock core prizing-proof cover being difficult to and being destroyed.
The technical scheme realizing the employing of foregoing invention mesh is as follows:
The lock core prizing-proof cover that the present invention provides, including the base plate being enclosed within lock core and being fixed on door skin, the cap with lock core end anastomosis that is fixed on base plate, cap is provided with rotary anti-drilling rotatable lamella, and anti-drilling rotatable lamella is provided with the perforate corresponding with the keyhole on lock core；Described base plate is provided with depressed part, matches with the depressed part on described base plate in the bottom of described cap, and the surface of the bottom of cap flushes with the surface of described base plate, is attached by screw between bottom and the base plate of cap.
Further technical scheme is to be positioned in described cap after described anti-drilling rotatable lamella and have additional another described anti-drilling rotatable lamella.
The lock core prizing-proof cover of the present invention, owing to matching with the depressed part on base plate in the bottom of cap, and the surface of the bottom of cap flushes with the surface of described base plate so that the bottom of cap and base plate do not have step, it is impossible to utilize this step to be fallen by cap sled with instrument.Have additional another anti-drilling rotatable lamella owing to being positioned in cap after described anti-drilling rotatable lamella again, add opposing instrument and destroyed the difficulty of lock core by keyhole.Therefore, the lock core prizing-proof cover of the present invention is greatly reinforced compared with the tamper-resistant function of prior art, and the lock core safety being furnished with lock core prizing-proof cover of the present invention is also greatly improved.
Below in conjunction with the accompanying drawings technical scheme is described further.

Detailed description of the invention
See Fig. 3 Fig. 6, the lock core prizing-proof cover that the present invention provides, including base plate 1 and with the cap 2 of lock core 6 end anastomosis, base plate 1 is provided with the installing hole 101 coincideing with lock core 6 profile, depressed part 102, the rivet hole 103 being connected with door skin A and the screw hole 104 being connected with cap 2, the bottom 201 of cap 2 is horizontal-extending shirt rim, the bottom 201 of cap 2 matches with the depressed part 102 on base plate 1, and its surface flushes with the surface of base plate 1, in cap 2 is provided with, the rotary anti-drilling rotatable lamella 3 ' of outer two panels, 3, the anti-drilling rotatable lamella 3 ' of two panels, the perforate 301 ' corresponding with the keyhole on lock core 6 it is respectively equipped with on 3, 301, it is provided with in cap 2 and prevents anti-drilling rotatable lamella 3 ', the inner sleeve 4 of 3 plaies.During installation, first the bottom 201 of cap 2 is put into the depressed part 102 on base plate 1, be screwed in through the screw hole 104 base plate 1 bottom cap 2 in the screw hole 202 on 201 from the inner face screw of base plate 1, cap 2 is fixed on base plate 1；Base plate 1 being enclosed within by installing hole 101 end of lock core 6 again, is fixed on door skin A by base plate 1 by rivet hole 103 rivet, lock core is protected by the end making cap 2 cover on lock core 6.
Cap 2 can use the size thicker than cap of the prior art, anti-drilling rotatable lamella 3 ', 3 can use high-strength material.Owing to not having step between bottom and the base plate 1 of cap 2, instrument is difficult to fall cap 2 sled.If one want to instrument inserts anti-drilling rotatable lamella 3 ', perforate 301 ' on 3,301 destroys lock cores 6, then cannot be able to realize because of the anti-drilling rotatable lamella 3 ' of two panels, the stop of 3.
