Abstract

The utility model relates to an antitheft lock unit comprising a bolt, a bushing and a key. The bolt comprises a lock disc and a bolt body. The lock disc and the bolt body are coaxially fixed. Three sockets coaxial with the bolt body are evenly and radially arranged in the lock disc at intervals. The bolt is coaxially nested in the bushing. The key comprises a key disc and a key stem; the key stem and the key disc are coaxially fixed. The key disc is provided with three pawls matching with the sockets in the lock disc. The antitheft lock unit has clear structure; the key disc and the key are designed together to achieve locking and unlocking; the sockets in the lock disc can rotate only when bearing three-point stress; a gap for only the lock disc to rotate in is reserved between the lock disc and the bushing, mounting stability of the lock disc is greatly improved, clamping and rotating with other tools or extending other tools into the sockets for prying is avoided, and using safety is guaranteed.

Description

A kind of theftproof lock assembly

Technical field

The utility model belongs to anti-theft device field, especially a kind of theftproof lock assembly.

Background technology

The current demand along with production application; increasing special-shaped lock; the lock core that is the regular geometric shapes such as built-in square or triangle is widely used; but due to scientific and technological progress; the key of untiing above-mentioned lock core is easy to produce; also lose thus theftproof performance, thereby lost the protection to various function door and windows.

Summary of the invention

The purpose of this utility model is to overcome prior art deficiency, and the theftproof lock assembly of the high and easy operating of a kind of safety factor is provided.

The technical solution adopted in the utility model is:

A kind of theftproof lock assembly, comprises dead bolt, lock tube and key, and described dead bolt comprises lock collar and locking bolt, and lock collar and locking bolt are coaxially fixedly mounted with, and in lock collar, spaced radial is uniform is provided with 3 and the homoaxial socket of locking bolt, and described dead bolt coaxial package is in lock tube; Described key comprises key floppy disc and the shank of the key, and the shank of the key and key floppy disc are coaxially fixedly mounted with, on key floppy disc, be provided with 3 with 3 pusher dogs that socket mates in lock collar.

And, between the lock collar of described dead bolt and lock tube inwall, leave the running clearance of 0.2～0.3mm.

And three sockets in described lock collar are inscribed within lock collar.

And described the shank of the key bottom vertical is fixedly mounted with a horizontal driving lever.

Advantage and good effect that the utility model adopts are:

The utility model clear in structure, complete locking and open by the supporting design of lock collar and key, in lock collar, three sockets must meet at 3 and stressedly could realize rotation, and between lock collar and lock tube, only leave for lock collar rotate gap, greatly improve the installation stability of lock collar, avoid clamping to rotate or stretch into socket by other instruments prizing, thereby ensured safety in utilization.
