Abstract

The utility model belongs to a destruction-proof lock device. When the destruction-proof lock device is installed on the outer layer of a lock, the lock can not be opened under the condition of having a key without password, and the main body of the lock can not be destroyed. The structure of the principle is that the piece of the lock of the utility model can be opened by the button of the password; if the piece of the lock is not opened, the key can not be inserted into the hole of the lock, the purpose of unlocking can not be achieved, and even the piece of the lock is opened, because the utility model is also provided with a destruction-proof piece, the core of the lock can also not be drilled by tools such as an electric drill, etc. to achieve the purpose of unlocking.

Description

Destruction-proof lock device

The utility model belongs to a kind of anti-theft device.

At present the door lock that uses is of a great variety, but generally all arrests in the mode of traditional lock, or anti-broken lock poor effect or structure loaded down with trivial details, its result of use and function are not ideal enough.

The purpose of this utility model provides the anti-broken locking device anti-broken lock function, simple in structure that has that a kind of and common lock be used.

Major technique content of the present utility model is to comprise base plate and shell, it is characterized in that having on the base plate common lock lockhole, be installed with two parallel locking plate location-plates vertical on the base plate on the top of common lock lockhole with base plate, have 4-10 locking plate positioning port on two locking plate location-plates, pack in the locking plate positioning port and the identical locking plate of locking plate positioning port quantity, pass an anti-broken lock arm-tie in the locking plate endoporus, there is anti-broken lock arm-tie handle the upper end of anti-broken lock arm-tie, the both sides of anti-broken lock arm-tie all have the anti-broken lock arm-tie groove identical with locking plate quantity, the outside of one of them locking plate location-plate is equipped with locking plate location reset button, the outside of another locking plate location-plate is equipped with the locking plate location activation button identical with locking plate quantity, be fit into an anti-drilling fragmentation between the door of base plate and its base plate of installation etc., have the keyhole bigger slightly on this anti-drilling fragmentation than key size, the locking plate endoporus divides two kinds of forms, first kind of form is for when locking plate location reset button is pressed, anti-broken lock arm-tie is passed through smoothly, when second kind of form located activation button for correctly press locking plate by password, anti-broken lock arm-tie is passed through smoothly, and the quantitative proportion of two kinds of locking plates is determined when design.

Using method of the present utility model is:

At first press locking plate location reset button, correctly press locking plate location activation button by password again, anti-broken lock arm-tie groove and locking plate endoporus are separated, use anti-broken lock arm-tie handle will prevent brokenly that the lock arm-tie waltzs through locking plate and is pulled upwardly, make the common lock lockhole be exposed to the situation that to insert key by anti-drilling fragmentation; Generally speaking, if do not press locking plate location reset button,,, prevent that broken lock arm-tie can not pass through, and causes common lockhole to expose and make because first kind of locking plate do not reset even correctly press locking plate location activation button by password; If locking plate is located reset button to be pressed, but correctly do not press locking plate location activation button,, the common lock lockhole can not be come out, play the effect of anti-broken lock in any case be to make anti-broken lock arm-tie by its locking plate by password yet; In addition, even owing to preventing that broken lock arm-tie draws back, because also have an anti-drilling fragmentation, even with things such as electric drill brill at that time,, and the common lock lockhole is exposed outside it owing to anti-drilling fragmentation rotates with drill bit.

Even advantage of the present utility model is key, if be ignorant of the password of this device, its second kind of locking plate resetted, common lockhole is come out; Even know the password of this device, but first kind of locking plate resetted, can't make outside common lockhole is exposed to yet; Even above two kinds of situations all solve, if no key, desire is opened with bit drills, but because the anti-drilling fragmentation that makes with the drill bit rotation is arranged, and still can't break to lock and go into.

Now provide embodiment of the present utility model as follows in conjunction with the accompanying drawings:

The utility model mainly comprises locking plate location reset button 1, shell 2, first kind of locking plate 3, second kind of locking plate 4, locking plate location-plate 5, locking plate positioning port 6, anti-drilling fragmentation 7, anti-broken lock arm-tie 8, anti-broken lock arm-tie handle 9, anti-broken lock arm-tie groove 10, locking plate endoporus 11, locking plate location activation button 12, base plate 13 formations such as grade, wherein, have the common lock lockhole on the base plate 13, be installed with parallel two locking plate location-plates 5 vertical on the base plate 13 on the top of common lock lockhole with base plate 13, have 4-10 locking plate positioning port 6 on two locking plate location-plates 5, the two kind locking plates 3 identical of packing in the locking plate positioning port 6 with locking plate positioning port 6 quantity, 4, pass an anti-broken lock arm-tie 8 in the locking plate endoporus 11, there is anti-broken lock arm-tie handle 9 upper end of anti-broken lock arm-tie, the both sides of anti-broken lock arm-tie 8 all have and two kinds of locking plates 3, the anti-broken lock arm-tie groove 10 that 4 quantity are identical, the outside of one of them locking plate location-plate 5 is equipped with locking plate location reset button 1, the outside of another locking plate location-plate 5 is equipped with the locking plate location activation button 12 identical with locking plate quantity, between the door of base plate 13 and its base plate 13 of installation etc. an anti-drilling fragmentation 7 is installed, have the keyhole bigger slightly on this anti-drilling fragmentation 7 than key size, 11 fens two kinds of forms of locking plate endoporus, first kind for when locking plate location reset button 1 is pressed, anti-broken lock arm-tie 8 is passed through smoothly, second kind is when correctly pressing locking plate location activation button 12 by password, just can make anti-broken lock arm-tie 8 pass through two kinds of locking plates 3 smoothly, 4 quantitative proportion is determined when design.

Operating principle of the present utility model and using method are as follows:

At first press locking plate location reset button 1, correctly press locking plate location activation button 12 by password again, anti-broken lock arm-tie groove 10 is separated with locking plate endoporus 11, use anti-broken lock arm-tie handle 9 will prevent brokenly that lock arm-tie 8 waltzs through locking plate 3,4 and is pulled upwardly, make the common lock lockhole be exposed to the situation that to insert key by anti-drilling fragmentation 7; Generally speaking, if do not press locking plate location reset button 1,,, prevent that broken lock arm-tie 8 can not pass through, and causes common lockhole to come out and make because first kind of locking plate 3 do not reset even correctly press locking plate location activation button 12 by password; If locking plate is located reset button 1 to be pressed, but correctly do not press locking plate location activation button 12,, common lockhole can not be come out, play the effect of anti-broken lock in any case be to make anti-broken lock arm-tie 8 by its locking plate 4 by password yet; In addition, even,,,, and the common lock lockhole is come out owing to anti-drilling fragmentation 7 rotates with drill bit even at that time with things such as electric drill brill because also have an anti-drilling fragmentation 7 owing to preventing that breaking lock arm-tie 8 draws back.
