Abstract

The utility model provides a lock core structure with anti-drilling function, which comprises a lock body and a lock core arranged in the lock body; the lock body is sleeved with a shell; a cavity is formed by enclosing the shell, the lock cylinder and the lock body; an anti-drilling sheet which covers the lock hole of the lock cylinder is placed in the cavity; the drilling-resistant sheet can rotate in the cavity; the key end of the existing lock core extending out of the door body is protected through the anti-drilling piece, so that the condition that the lock body is opened due to the fact that the drill bit is damaged easily outside is avoided.

Description

Lock core structure with anti-drilling function

Technical Field

The utility model relates to a tool to lock technical field, concretely relates to lock core structure with prevent boring function.

Background

The lock comprises a lock body arranged on a door body and a lock cylinder structure penetrating through the door body, and the existing lock cylinder structure directly exposes the lock cylinder, so that a key can be conveniently inserted into the lock cylinder to match and then the lock cylinder is rotated, and the lock body is opened.

The lock core is directly exposed to the outside by the existing lock core structure, the lock body is easily opened after the lock core is damaged by directly passing through a drill bit outside, and the risk of damage exists.

Disclosure of Invention

Not enough to exist among the prior art, the utility model provides a lock core structure with prevent boring the function has solved the lock key end of current lock core and has directly exposed the problem of opening the tool to lock main part after receiving the drill bit destruction easily in the external world.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a lock core structure with a drilling-proof function comprises a lock body and a lock core arranged in the lock body; the lock body is sleeved with a shell;

a cavity is formed by enclosing the shell, the lock cylinder and the lock body;

an anti-drilling sheet which covers the lock hole of the lock cylinder is placed in the cavity;

the anti-drilling plate can rotate in the cavity.

Preferably, the anti-drilling sheet comprises a shell structure with an opening on one side and a columnar structure, and a limiting sheet fixedly connected to the edge of the opening of the shell structure;

the shell structure is provided with a key hole matched with the lock hole of the lock core.

Preferably, an annular side gap is formed between the lock core and the lock body;

and the limiting sheet is provided with a rotating ring which is in rotating fit with the annular side gap.

Preferably, the anti-drilling piece is of an integrated punch forming structure.

Preferably, the lock body is provided with two mounting holes for fixing the shell.

Compared with the prior art, the utility model discloses following beneficial effect has:

the anti-drilling piece is arranged in the cavity enclosed among the shell, the lock cylinder and the lock body, so that the anti-drilling piece can rotate in the cavity, and when the drill bit is damaged outside, the anti-drilling piece can rotate synchronously with the drill bit, so that the drill bit becomes an idle drill, and the situation that the drill bit further moves to damage the lock cylinder is avoided; simultaneously, can shelter from the backlash between lock core and the lock body through the effect of preventing the piece that bores, also can avoid the lock core to a certain extent by the condition of sled and destruction.

Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1, an embodiment of the present invention provides a lock cylinder structure with an anti-drilling function, including a lock body 1 and a lock cylinder 2 installed in the lock body 1; the lock body 1 and the lock cylinder 2 are both of the existing structure, the lock body 1 is sleeved with the shell 3, the lock body 1 is coated by the shell 3 and then can be adapted to a lock mounting structure, and the lock body 1 has a certain protection effect; after the shell 3 is installed, a cavity is enclosed among the shell 3, the lock cylinder 2 and the lock body 1, and the cavity is positioned outside the installation door body; in order to realize the drilling prevention of the lock cylinder 2, a drilling prevention piece 4 covering the lock hole of the lock cylinder 2 is placed in the cavity, and the drilling prevention piece 4 can rotate in the cavity; the anti-drilling plate 4 only can allow a key to pass through and shields the formed side gap; when the lock cylinder 2 is damaged through the drill bit outside, idle rotation is formed after the drill bit contacts the anti-drill sheet 4, the drill bit cannot be further damaged after idle rotation, and the anti-drill sheet 4 is made of a metal material with high strength and has a certain anti-damage effect.

As shown in fig. 3 and 4, the anti-drilling plate 4 includes a housing structure 41 with an opening on one side and a columnar structure, and a limiting plate 42 fixed to the edge of the opening of the housing structure 41, and the housing structure 41 is provided with a key hole 43 matching with the lock hole of the lock cylinder 2; the key can pass through the key hole 43 but cannot pass through the drill bit, the limiting piece 42 can be limited by the shell 3 after being placed in the cavity, and the whole anti-drilling piece 4 can form relative rotation on the shell 3 under the action of the limiting piece 42 and cannot slide out.

As shown in fig. 2, an annular backlash 5 is provided between the key cylinder 2 and the lock body 1, and in order to further play a role of positioning and guiding the rotation of the anti-drilling plate 4, a rotating ring 6 which is rotatably matched with the annular backlash 5 is provided on the limiting plate 42, and the positioning and rotating guiding effects are achieved through the relative rotation between the rotating ring 6 and the annular backlash 5.

In order to facilitate the processing and manufacturing of the whole anti-drilling plate 4, the anti-drilling plate 4 is of an integral punch forming structure.

As shown in fig. 2, two mounting holes 10 for fixing the housing 3 are formed in the lock body 1 for positioning and locking the housing 3 when the housing 3 is mounted.

After the structure of the lock core in the embodiment is improved, the anti-drilling piece 4 freely rotates in the cavity, so that when an external drill bit is damaged, the drill bit can idle, and the condition that the lock core 2 is damaged outside is avoided; simultaneously, the back is sheltered from with the sideshake between shell 3 and the lock body 1 to anti-drill piece 4, also can avoid the condition that lock core 2 was prized to a certain extent.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
