Summary of the invention
The object of this invention is to provide a kind of lock core prizing-proof cover being difficult to be destroyed.
The technical scheme realizing the employing of foregoing invention order is as follows:
Lock core prizing-proof cover provided by the invention, comprise be enclosed within lock core and be fixed on base plate on door skin, be fixed on base plate with the cap of 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 the keyhole on lock core; Described base plate is provided with pilot hole with bayonet, the bottom of described cap is provided with outside chimb, described base plate is enclosed within described cap by described pilot hole, and to be matched with the chimb on the bottom of described cap by the bayonet socket on pilot hole cap fixed, the chimb on bottom described cap and being connected by screw between described base plate.
What be positioned at described anti-drilling rotatable lamella in described cap has additional anti-drilling rotatable lamella described in another below.
Described base plate is provided with the screw holding head of screw, and in described screw, interference fit is provided with block head by head of screw shutoff, and the surface of block head flushes with the surface of described base plate.
Described block head side is provided with sawtooth, and block head is by the screw interference fit on the sawtooth of side and described base plate.
Beneficial effect of the present invention: one is that base plate adopts bayonet socket to match with the bottom of cap, can eliminate the weak part between cap and base plate, is difficult to be fallen by cap sled with instrument; Two are and below have additional another anti-drilling rotatable lamella due to what be positioned at described anti-drilling rotatable lamella in cap, add opposing instrument destroys lock core difficulty by keyhole; Three is adopt block head to block screw, can prevent knockout screw from destroying lock core; Four is adopt to establish serrate block head can improve the effect of shutoff screw.Lock core prizing-proof cover of the present invention is strengthened greatly compared with the tamper-resistant function of prior art, and the safety of being furnished with the lock core of lock core prizing-proof cover of the present invention is also greatly improved.
Below in conjunction with accompanying drawing, technical scheme of the present invention is described further.

Detailed description of the invention
Embodiment 1
See Fig. 3---Fig. 4, lock core prizing-proof cover provided by the invention, comprise and being enclosed within lock core 6 and the base plate 1 be fixed on door skin A and the cap 2 with lock core 6 end anastomosis, 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 is respectively equipped with on 3, 301, be provided with in cap 2 and prevent anti-drilling rotatable lamella 3 ', the inner sleeve 4 of 3 plaies, base plate 1 is provided with the pilot hole of band bayonet socket 101, the bottom of described cap 2 is provided with outside chimb 201, base plate 1 is enclosed within cap 2 by pilot hole, and to be matched with the chimb 201 on bottom cap by the bayonet socket 101 on pilot hole cap 2 fixed, connected by screw 8 between chimb 201 on bottom cap 2 and base plate 1.During installation; first by the end covering on lock core 6 of cap 2; again base plate 1 is covered on cap 2, to be screwed on base plate 1 through door skin A with screw 8 from the fixed head 7 inside door skin A and cap 2 and base plate are fixed on door skin A, lock core 6 is protected.
Embodiment 2
See Fig. 5, in the present embodiment, described base plate 1 is provided with the screw of the head of screw 801 holding screw 8, in screw, interference fit is provided with block head 9 by dead for head of screw 801 shutoff, the surface of block head 9 flushes with the surface of base plate 1, as shown in Figure 6, Figure 7, the side of block head 9 is provided with sawtooth 901, and block head 9 is by the sawtooth 901 of side and the screw interference fit on described base plate 1.Because the sawtooth 303 on block head 3 adds the contact area with screw, block head 3 and the interference fit effect of screw can be improved, add the difficulty of dismounting block head 3 simultaneously.The edge of block head 9 is provided with the chamfering 902 of taper, facilitates block head 9 to enter in screw.
Cap 2 in the present invention can adopt the size thicker than cap of the prior art, and anti-drilling rotatable lamella 3 ', 3 can adopt high-strength material.Owing to not having weak part between cap 2 and base plate 1, instrument is difficult to cap 2 to prize.If want that the perforate 301,301 ' of being inserted on anti-drilling rotatable lamella 3,3 ' by instrument destroys lock core 6, then cannot be able to realize because of the stop of the anti-drilling rotatable lamella 3,3 ' of two panels.
