Embodiment Construction

[0034] A mechanical tumbler combination lock cylinder and a key, including a lock cylinder and a key.

[0035] The lock cylinder is composed of an outer lock cylinder 1 and an inner lock cylinder 2 (the present invention mainly highlights the mechanical characteristics of the lock cylinder of the present invention, omitting the design of some parts of the lock cylinder, such as the axially fixed fastener of the inner lock cylinder and the rotation of the inner lock cylinder Limiting firmware), the middle part of the inner lock cylinder 2 has the movable unlocking key teeth insertion groove 8 of the inner lock cylinder and the fixed twisting key teeth insertion groove 9 of the inner lock cylinder, and the locking function of the lockset is realized by 3-10 sets of locking units 16.

[0036] The outer lock cylinder 1 of the lockset is equipped with an outer lock cylinder locking pin 12 inside; the inner lock cylinder 2 of the lockset is equipped with an inner lock cylinder lockin...

Abstract

The invention relates to a mechanical pin tumbler coded lock cylinder and a key, and relates to the technical field of mechanical pin tumbler coded locks. An ordinary pin tumbler lock is simple in structure and low in cost, but extremely poor in safety; although a complex lock has high safety, the structure is complicated and the cost is high; and the key teeth of an ordinary key are fixed, whichare easily copied maliciously. The invention designs a mechanical pin tumbler coded lock cylinder and a key. The invention has the following characteristics: theoretically, the lock encryption can berealized by any plurality of sets of encryption units, and a single set of encryption units can theoretically have any plurality of unlocking directions, so this lock can be synthesized into a lock ofany encryption level by changing the number of the sets of encryption units and the unlocking directions of the encryption units. The lock is simple in structure and low in cost, the technical realization and economical efficiency are good, the safety of the lock is extremely high, and even if the key is lost, the safety of the lock is not affected.

Description

Technical field [0001] The invention belongs to the technical field of mechanical pin combination locks. Background technique [0002] Locks are important equipment for people to protect property in daily life, and the importance of locks is self-evident. [0003] Ordinary tumbler locks are simple in structure and low in cost, but extremely poor in security; complex locks are highly secure, but complex in structure and high in cost; the key teeth of general keys are fixed key teeth, which are easy to be maliciously imitated, and the loss of the key is even more serious. Will greatly affect the security of the lock. Contents of the invention [0004] Due to the common problems of existing locksets that it is difficult to balance safety and economy, and the safety cost of losing the fixed key teeth is extremely high, the present invention designs a mechanical tumbler combination lock cylinder and key. [0005] The technical solution adopted by the present invention to real...
