Problems solved by technology
Due to the simple structure, the interlocking property of the lock itself is poor, and it is easy to be opened by a master key, or it can be opened by a small destructive force from the outside, and the security of the lock is poor.
For safe deposit boxes used by banks to store valuables, the safety requirements are higher, and the existing commonly used mechanical locks can no longer meet the needs of its safety performance. Head mechanical lock is particularly urgent

The invention belongs to the technical field of door locks, and particularly discloses a double-end mechanical lock. The mechanical lock comprises a box body, a cap body and a bolt, wherein a master lockhole and an auxiliary lockhole are arranged from the cap body to the inside of the box body, a master key penetrates through the master lockhole, and an auxiliary key penetrates through an auxiliary lockhole; a long lock core which penetrates through the master lockhole is arranged in the master lockhole; a short lock core is arranged inside the auxiliary lockhole mounted in the cap body; and an interlocking device, which can unlock the bolt only by orderly opening the master key and the auxiliary key, is arranged in the box body. The double-end mechanical lock has the advantages of favorable interlocking performance, high anti-theft performance, and safe and reliable operation, realizes multiple-person checking management, and ensures high safety and anti-theft performance of the safety deposit boxes in the bank.
Description
technical field [0001] The invention belongs to the technical field of door locks, in particular to a double-head mechanical lock. Background technique [0002] The mechanical door locks currently used are all combined with a lock head and a lock cylinder, and are opened by a key. Due to the simple structure, the interlocking property of the lockset itself is poor, and it is very easy to be opened by a master key, or it can be opened by a small destructive force from the outside, and the security of the lockset is relatively poor. For safe deposit boxes used by banks to store valuables, the safety requirements are higher, and the existing commonly used mechanical locks can no longer meet the needs of its safety performance. Head mechanical locks are particularly urgent. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a double-headed mechanical lock, which has good interlocking performanc...
