Embodiment 1

[0011] Example 1: Take three cipher circles as an example (1) During the installation process, the inner end of the pin shaft is put into the spring 2, and then into the pin shaft 9, and the positioning linkage rod 3 passes through the shell and the pin shaft 9 through the milling hole 10 Fixed connection, under the tension of the spring 2, the positioning linkage rod 3 is positioned as figure 1 In terms of position, at this time, each steel ball hole on the bolt shaft 9 is just aligned with each steel ball hole on the inner casing, and the steel ball 6 is put in from the steel ball hole of the inner casing, and the bottom of the steel ball 6 just falls on the bottom of the bolt shaft 9. In the steel ball hole, the top of the steel ball 6 is just flat with the outer wall of the inner casing 7 . (Steel ball diameter=inner sleeve wall thickness+bolt shaft steel ball hole depth), insert the first code ring 4 from the inner sleeve 7, the inner wall of the code ring 4 presses the ...

Embodiment 2

[0012] Embodiment 2: Assuming that with 5 or more cipher circles as an example, the specific implementation process of the present invention will be further described below in conjunction with the accompanying drawings:

[0013] (1) Installation process: same as embodiment 1.

[0014] (2) Use process: same as embodiment 1.

Abstract

The invention relate to a mechanical coded lock which is technically characterized in that a stud shaft is arranged in the center of a shell of the lock; a bayonet is arranged at the outer end of the stud shaft; a spring is arranged at the inner end of the stud shaft; the stud shaft is provided with three or more steel ball holes with equal distance in a group; two code rings and a code-correcting ring are arranged outside an inner sleeve tube; one code-correcting ring is arranged between the two code rings; the shell is also provided with a milling port; a positioning link rod drives the stud shaft to laterally translate under the action of external force; and since the mechanical coded lock achieves the on / off aims, the invention has the advantages of simple structure, low cost, convenient use and the like, and is suitable for bicycles, motorcycles, electric motor cars and other devices without fixed attachments.

Description

1. Technical field [0001] The invention relates to a lock set unlocked by a code, in particular to a rolling mechanical code lock unlocked by rotating a code circle. 2. Background technology [0002] At present, the known mechanical combination locks include key-type and dial-type locks, some of which have more complex structures; Body fittings are not applicable. 3. Contents of the invention [0003] In order to overcome the deficiencies of existing mechanical combination locks, the present invention provides a rolling type mechanical combination lock with simple structure, convenient use and low cost. [0004] The technical solution adopted by the present invention to solve the technical problem is: a rolling mechanical combination lock, which includes a shell, a spring, a positioning link, a code ring, a code change ring, steel balls, an inner sleeve, an outer sleeve, a bolt shaft, and a milling opening. , password circle steel ball hole and so on. It is characterize...
