Abstract
The utility model discloses an anti- violence torsion anti-picking lock core, and the anti- violence torsion anti-picking lock core comprises a lock shell body and a lock core body, wherein the lock core body is arranged in a core chamber of the lock shell body. The middle portion of the core chamber is provided with a shaft chamber in a disconnecting and communicating mode. A cam shaft is arranged inside the shaft chamber, and the cam shaft is arranged on a shifting coupling of the lock core body. At least one end of the two ends of the lock shell body is provided with a separating lock shell, and the separating lock shell is separated from the lock shell body. A partial portion between the separating lock shell and the lock shell body is connected with a first copula. A separating groove is arranged around the first copula. By the adoption of the structure, the separating lock shell is arranged on the outer end portion of the lock shell body, and the separating lock shell is combined with the lock shell body through the partial portion, and the separating groove is arranged on the periphery of the copula to be a portion more fragile than a lock beam. When a thief picks and twists the lock with violence, the separating lock shell is damaged before the lock beam, and at the same time, the cam shaft can not be taken out, so the lock is still anti-theft.
Description
Technical field
The utility model relates to lock technology field, says that more specifically a kind of anti-violence reverses prizing-proof lock core.
Background technology
Lock core such as the ZL201120324977.0 record, comprises lock housing body and lock gall body, the lock gall body is arranged in the core chamber of lock housing body, core chamber middle part disconnects being communicated with and is provided with axocoel, is provided with camshaft in the axocoel, and camshaft is arranged on the connector on the lock gall body.
Burglar's violence picking lock in the middle of our daily life, often use very large external force twistlock shell body, and the lock housing body is because the middle part needs to vacate a part axocoel is set, so just fragile especially at the lock bridge place that connects axocoel two ends lock housing body, usually reverse through external force one, lock bridge just very easily is broken, thereby camshaft just can be removed, and lock just is opened.
The utility model content
The purpose of this utility model is the defective of unblanking after overcoming the prior art lock core is reversed by violence easily to provide a kind of simple in structure, easy to manufacture, safe anti-violence to reverse prizing-proof lock core.
In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of anti-violence reverses prizing-proof lock core, comprise lock housing body and lock gall body, the lock gall body is arranged in the core chamber of lock housing body, middle part, core chamber disconnects being communicated with and is provided with axocoel, be provided with camshaft in the axocoel, camshaft is arranged on the connector on the lock gall body; It is characterized in that one of them end in lock housing body two ends is provided with it is separated and separates lock housing, separate that the part is connected with junction surface one between lock housing and the lock housing body, junction surface one is circumferentially with separating tank.
Burglar's violence picking lock in the middle of our daily life, often use very large external force twistlock shell body, and the lock housing body is because the middle part needs to vacate a part axocoel is set, so just fragile especially at the lock bridge place that connects axocoel two ends lock housing body, usually reverse through external force one, lock bridge just very easily is broken, thereby camshaft just can be removed, and lock just is opened.
Therefore, the utility model is for above this situation, outboard end at the lock housing body arranges a separation lock housing, and combine with the lock housing body by local, in this periphery, junction surface, place separating tank is set and makes it become the part more fragile than lock bridge, when burglar's violence picking lock reversed, this separation lock housing had precedence over lock bridge and is destroyed, this moment, camshaft still can not be got out, and lock remains antitheft; In addition, separate lock housing and also be whole lock housing body expose security door outer part only arranged, it is destroyed, the burglar reverses origin of force without instrument again; But, because the lock gall body rotates with respect to the lock housing body, sustain damage reversing Shi Buhui, the user still can open lock by key.
As preferably, separate lock gall with adaptive on lock gall body respective ends, also being provided with it is separated of lock housing body, separate that the part is connected with junction surface two between lock gall and the lock gall body, junction surface two circumferentially also is provided with separating tank.
After the separation lock housing is destroyed, the burglar reverses origin of force without instrument again, this moment is because the lock gall body rotates with respect to the lock housing body, sustain damage reversing Shi Buhui, so the burglar might reverse origin of force as the next one with this barish lock gall body, still has the destroyed possibility of lock bridge, therefore more the way of insurance is the also supporting separation lock gall that arranges of lock gall body, and suitable with the lock housing body, convenient when processing like this.
As preferably, the lock housing body wherein an end be provided with it is separated and separate lock housing; Adaptive with the lock housing body, on lock gall body respective ends, also be provided with it is separated and separate lock gall.
One end only is set, and processing is simple, bothers less in the time of installation, need to select to have separating end in the security door outside.
As the alternative of such scheme, be provided with at lock housing body two ends with it is separated and separate lock housing; Adaptive with the lock housing body, on lock gall body two ends, also be provided with it is separated and separate lock gall.
Processing a trouble of bringing in more only is set, but need not to select the end when installing, arbitrarily install.
Beneficial effect: the utility model is for above this situation, outboard end at the lock housing body arranges a separation lock housing, and combine with the lock housing body by local, in this periphery, junction surface, place separating tank being set makes it become the part more fragile than lock bridge, when burglar's violence picking lock reverses, this separation lock housing has precedence over lock bridge and is destroyed, and this moment, camshaft still can not be got out, and lock remains antitheft; In addition, separate lock housing and also be whole lock housing body expose security door outer part only arranged, it is destroyed, the burglar reverses origin of force without instrument again; But, because the lock gall body rotates with respect to the lock housing body, sustain damage reversing Shi Buhui, the user still can open lock by key.
