Key and giant lock assembly based on same

Abstract

The invention discloses a key and a giant lock assembly based on the same. A giant lock (2) further comprises a lock unlocking post (6) and a lock unlocking pin (7), wherein the lock unlocking post (6) is arranged at the tail end of a lock cylinder (5) and coaxial with the lock cylinder (5); and one end of the lock unlocking pin (7) is connected with the lock unlocking post (6), and rotation of the lock unlocking post (6) enables the lock unlocking pin (7) to slide up and down. The other end of the lock unlocking pin (7) can be in limit fit with a lock pin groove (401) for achieving locking; a clearance is formed between the tail end of the lock cylinder (5) and the end, away from the lock unlocking pin (7), of the lock unlocking post (6); and one end of a key body (102) can penetrate through the lock cylinder (5) to be inserted into the lock unlocking post (6), so that the lock unlocking post (6) is driven to rotate, and the lock unlocking pin (7) is made to slide downwards until the limiting of the lock unlocking pin (7) and the lock pin groove (401) is released, so that the lock is unlocked. The key and the giant lock assembly based on the same have the advantage that the assembly is good in safety performance.

Description

technical field [0001] The invention relates to a combination of a key and a giant lock based on the key. Background technique [0002] Existing giant lock, its structure is basically the same as the disclosed lockset of the patent application document of 201210516880.9 as the patent No., concrete structure comprises lock case, and lock case is provided with lock bar hole and lock core hole, lock bar hole and lock The core holes are connected; the lock rod is arranged in the lock rod hole and can move along the lock rod hole. The lock rod is provided with a lock pin groove, and the lock core is arranged in the lock core hole. And at least one group of marble hole groups, the lock pin hole is equipped with a lock pin and a lock pin spring, the shape of the top of the lock pin matches the lock pin groove, the two ends of the lock pin spring are respectively connected with the lock pin and the inner wall of the lock pin hole, and the lock pin The hole is equipped with a lock p...

Problems solved by technology

[0004] Analysis of the above structure shows that the key in the lockset is inserted into the lock core of the lockset, and the lock pin can move up and down in the lock pin hole under the condition that the key matches the pin hole group, and the purpose of unlocking is achieved. In this type of lock, the key only needs to match the pinhole group in the lock cylinder to achieve the purpose of unlocking. In this way, with the help of unlocking guns, steel sheets, screwdrivers and other unlocking tools, it is easy to dial directly into the keyhole. Move or even destroy the pin in the lock cylinder, the lock can be forcibly opened in a short time, resulting in poor anti-theft performance
