Abstract

The utility model relates to a technical field of security lock, in particular, is a new type security lock and key, including a shell, a bushing, a lock core, a spring and a marble, which is characterized in that the key slot built in the lock core is S-shape, the shell and bushing which are corresponding to the key slot are provided with marble holes in which the cylindrical marble, spring and spring pore plug are arranged. Compared with the current technology, the utility model changes the internal structure of traditional lock and designs the keyslot in the lock core as S-shape. Only when the key is inserted into the lock and becomes curved, can the lock be opened, which means skeleton key is no use, the safety coefficient is greatly improved. Furthermore, the utility model is simple in structure, low in cost and worth promoting.

Description

Novel anti-burglar lock and key

[technical field]

The utility model relates to the theftproof lock technical field, specifically a kind of novel anti-burglar lock and key.

[background technology]

Along with locking the growing of industry, the common theftproof lock with the direct insertion unlatching of key has of all kinds in the life now, as long as people use the key straight cutting that matches with this tapered end to go into lockhole, just can open this tapered end, adopt master key or iron wire to raise like this and stir pellet shot from a slingshot into lock core, just be easy to the lock milli is nondestructively opened, thereby cause the safety factor of this theftproof lock to reduce greatly.

[summary of the invention]

The purpose of this utility model be exactly to solve above-mentioned deficiency and provide a kind of more can safe and reliable novel anti-burglar lock and key.

For achieving the above object, the utility model proposes a kind of novel anti-burglar lock, comprise housing, sleeve, lock core, spring, pellet shot from a slingshot, the key that it is characterized in that lock core inside is the S type, with corresponding housing of key and sleeve on have the pellet shot from a slingshot hole, cylindrical billiard, spring and spring stopple are housed in the pellet shot from a slingshot hole; The key bit of described key is a flaky texture, key bit adopt intensity and toughness mutually and the metal material of depositing make.

The utility model is compared with prior art, changed the internal construction of traditional locks, the key of lock core inside is designed to the S type, key just can be opened lock after inserting and becoming case of bending in the lock, and this just means that also master key has lost effect, and safety factor improves greatly, in addition, the utility model is made simple, and cost is low, is worthy of popularization.
