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 security door use.In order to prevent that thief from being opened the door and being stolen by destruction lock core, conventionally installs in addition lock core prizing-proof cover in the outside of door leaf the end of lock core is covered.Existing lock core prizing-proof cover as shown in Figure 1 and Figure 2, comprise and be enclosed within on lock core 6 and be fixed on base plate 1 on door skin A, be fixed on the cap 2 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 keyhole on lock core 6, is provided with the fixedly inner sleeve 4 of rotatable lamella 3 in cap 2.The problem that existing lock core prizing-proof cover exists is, the one, and cap 2 is connected with base plate 1 by rivet 5, has a step between the bottom of cap 2 and base plate 1, is easy to utilize this step that cap 2 is prized with instrument, reaches the object of destruction lock core; The 2nd, the perforate 301 that can use high strength instrument to insert rotatable lamella 3, by rotatable lamella 3 spreadings, then the keyhole that continues to insert lock core 6 is by lock core 6 destructions.
Summary of the invention
The object of this invention is to provide a kind of destroyed lock core prizing-proof cover that is difficult to.
The technical scheme that realizes the employing of foregoing invention order is as follows:
Lock core prizing-proof cover provided by the invention, comprise and be enclosed within on lock core and be fixed on base plate on door skin, be fixed on base plate and 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 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 on described cap by described pilot hole, and match cap is fixed by the chimb on the bottom of the bayonet socket on pilot hole and described cap, between the chimb on described cap bottom and described base plate, by screw, connect.
What in described cap, be positioned at described anti-drilling rotatable lamella has additional below anti-drilling rotatable lamella described in another.
Described base plate is provided with the screw that holds head of screw, and in described screw, interference fit is provided with block head by head of screw shutoff, the surface of block head and the flush of described base plate.
Described block head side is provided with sawtooth, and block head is by the sawtooth of side and the screw interference fit on described base plate.
Beneficial effect of the present invention: the one, 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 instrument, cap be prized; The 2nd, due to what be positioned at described anti-drilling rotatable lamella in cap, below have additional another anti-drilling rotatable lamella again, increase opposing instrument and by keyhole, destroyed the difficulty of lock core; The 3rd, adopt block head to block screw, can prevent knockout screw destruction lock core; The 4th, adopt and establish the effect that serrate block head can improve 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.

The specific embodiment
Embodiment 1
See Fig. 3---Fig. 4, lock core prizing-proof cover provided by the invention, comprise be enclosed within on lock core 6 and be fixed on base plate 1 on door skin A and with the cap 2 of lock core 6 end anastomosis, in cap 2 is provided with, outer two rotary anti-drilling rotatable lamellas 3 ', 3, two anti-drilling rotatable lamellas 3 ', on 3, be respectively equipped with the perforate 301 corresponding with keyhole on lock core 6 ', 301, in cap 2, be provided with prevent anti-drilling rotatable lamella 3 ', the inner sleeve 4 of 3 plaies, base plate 1 is provided with the pilot hole with bayonet socket 101, the bottom of described cap 2 is provided with outside chimb 201, base plate 1 is enclosed within on cap 2 by pilot hole, and match cap 2 is fixing by the bayonet socket 101 on pilot hole with the chimb 201 on cap bottom, between chimb 201 on cap 2 bottoms and base plate 1, by screw 8, connect.During installation; first by the end that covers on lock core 6 of cap 2; again base plate 1 is covered on cap 2, from the fixed head 7 use screws 8 of door skin A the inside, through door skin A, be screwed on base plate 1 cap 2 and base plate are fixed on to door skin A above, 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 that holds screw 8, the interior interference fit of screw is provided with block head 9, and head of screw 801 shutoff are dead, the flush of the surface of block head 9 and 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 has increased the contact area with screw, can improve the interference fit effect of block head 3 and screw, increased 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, anti-drilling rotatable lamella 3 ', 3 can adopt high-strength material.Owing to there is no weak part between cap 2 and base plate 1, instrument is difficult to cap 2 sleds to fall.If want by instrument insert anti-drilling rotatable lamella 3,3 ' on perforate 301,301 ' destruction lock core 6, can because of two anti-drilling rotatable lamellas 3,3 ' stop and cannot realize.
