Description

Technical Field

[0001] This utility model relates to the field of lock cylinders, specifically an anti-drill lock cylinder. Background Technology

[0002] Double-lock locks are very common in daily life, consisting of an outer lock cylinder and an inner lock cylinder, which are installed on the inside and outside of the door respectively. With existing lock cylinder structures on the market, when a key is inserted into either the inner or outer lock cylinder, the key cannot be inserted into the other lock cylinder.

[0003] A Chinese patent application with application number CN202323621035.0 discloses a lock cylinder with a relatively cumbersome and complex unlocking structure that needs improvement. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-drill lock cylinder to solve the problems mentioned in the background art. It has the advantage of improving the connection relationship between the outer lock cylinder assembly, the dial wheel and the inner lock cylinder assembly to facilitate assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-drill lock cylinder, comprising a housing, an outer lock cylinder assembly, a dial, and an inner lock cylinder assembly located within the housing. The outer lock cylinder assembly includes an outer lock cylinder, a first slot is provided on one side of the outer lock cylinder, the outer lock cylinder is engaged with a first locking block through the first slot, the first locking block is integrally connected to a first locking ring, a second locking block is integrally connected to the end of the first locking ring away from the first locking block, the first locking ring is engaged with a first connecting ring through the second locking block, the first connecting ring is provided with a second slot engaged with the second locking block, a third locking block is integrally connected to the side of the first connecting ring, and the dial is provided with a third slot for accommodating the third locking block.

[0006] By adopting the above technical solution, the first slot rotates with the rotation of the outer lock cylinder, causing the first locking block to rotate, which in turn causes the first locking ring to rotate. The rotation of the first locking ring causes the second locking block to rotate, which in turn causes the first connecting ring, which is engaged with the second locking block, to rotate. The rotation of the first connecting ring causes the third locking block to rotate, which in turn causes the dial wheel, which is engaged with the third locking block, to rotate. The rotation of the dial wheel can drive the lock block to rotate.

[0007] It is worth noting that this solution improves the connection relationship between the outer lock cylinder assembly, the dial, and the inner lock cylinder assembly.

[0008] As a further embodiment of this utility model: the inner lock cylinder is provided with a fourth slot at one end of the dial, the fourth slot is engaged with a fourth block, the fourth block is integrally connected with a second ring, the second ring is provided with a fifth slot, the fifth slot is engaged with a fifth block, the fifth block is integrally connected with a second connecting ring, the side of the second connecting ring is integrally connected with a sixth block, and the third slot provided on the inner side of the dial is engaged with the sixth block.

[0009] By adopting the above technical solution, the fourth slot rotates with the rotation of the inner lock cylinder, which in turn drives the fourth locking block to rotate. The rotation of the fourth locking block drives the second locking ring to rotate, which in turn drives the fifth locking block to rotate. The rotation of the fifth locking block drives the second connecting ring to rotate, which in turn drives the sixth locking block to rotate. The rotation of the sixth locking block drives the dial wheel to rotate, which in turn drives the lock block to rotate.

[0010] As a further improvement of this utility model, a spring is provided between the first retaining ring and the second retaining ring.

[0011] By adopting the above technical solution, the spring is configured to allow the first retaining ring and the second retaining ring to move in a direction that moves away from each other.

[0012] As a further embodiment of this utility model: a groove is provided on the top of the shell, a reinforcing block is installed in the groove, the reinforcing block is connected to the shell by bolts, and the reinforcing block and the shell are connected by the same pin.

[0013] By adopting the above technical solution, the reinforcing block is placed in the groove and connected to the shell by bolts and pins to increase the strength of the shell.

[0014] As a further improvement of this utility model: a first limiting ring is provided between the outer locking cylinder and the dial wheel, and a second limiting ring is provided between the inner locking cylinder and the dial wheel.

[0015] By adopting the above technical solution, the setting of the first and second limiting rings reduces the wear between the outer locking cylinder, the inner locking cylinder, and the dial wheel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] As the outer lock cylinder rotates, the first locking slot causes the first locking block to rotate, which in turn causes the first locking ring to rotate. The rotation of the first locking ring causes the second locking block to rotate, which in turn causes the first connecting ring, which is engaged with the second locking block, to rotate. The rotation of the first connecting ring causes the third locking block to rotate, which in turn causes the dial wheel, which is engaged with the third locking block, to rotate. The rotation of the dial wheel causes the lock block to rotate.

[0018] It is worth noting that this solution improves the connection relationship between the outer lock cylinder assembly, the dial, and the inner lock cylinder assembly. Attached Figure Description
