Embodiment Construction

[0013] Installation process: in figure 1 Among them, each code change ring 3 is inserted into the gear ring 2, (the password number and position are set before inserting) to form a code ring 1, and each code ring 1 is put into the code hole 6 on the shell 5 Inside, the lock shaft 11 passes through each combination circle 1 from left to right through the casing 5, and when passing through the combination circle 1, the angles of the two tooth holes 12 and 13 are adjusted by rolling through it, so that the two teeth in the gear ring 2 The holes 12, 13 are aligned with the two groups of password teeth 8, 9 on the lock shaft 11, and each of them is passed through in turn, and each password number aligned with the scale line 17 is remembered when passing through, that is, the password of this lock combination. Load onto positioning plate 4,18 on both sides at last, every positioning plate 4,18 is fixed with screw by screw hole 10, and installation is completed.

Abstract

The invention discloses a mechanical coded lock, which achieves the purpose of preventing technical unlocking through the designs of different heights and left-right staggering of code teeth, formation of a trap hole in a code hole and the like. In unlocking and locking states, a code ring can be rotated without reserving traces. Therefore, the mechanical coded lock has the advantages of good confidentiality, using convenience, simple structure and low manufacturing cost, and is suitable for theft-proof settings of bicycles, motorcycles, electric vehicles, theft-proof doors, garage doors and the like.

Description

technical field [0001] The invention relates to a lock set unlocked by a code, in particular to a mechanical code lock unlocked by rotating a code circle. Background technique [0002] At present, known mechanical coded locks include key-press type and coded locks that rotate coded circles by rollers. The structure of the key-type combination lock is complicated, and fingerprints will be left after each key is pressed, and the password is easily exposed. When the coded lock of rolling password circle type is in the unlocked state, the coded circle cannot be rotated, so the password is easy to be found by people when the lock is in the unlocked state, and the lock is easy to be opened technically. Contents of the invention [0003] In order to overcome the deficiencies of the existing mechanical combination locks, the present invention provides a mechanical combination lock with simple structure, convenient use, low cost and technically difficult opening. [0004] The tec...
