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

Rolling type mechanical coded lock

One, technical field

The present invention relates to a kind of lockset, especially refer to rotate the rolling type mechanical coded lock of the mode release of password circle through unlock password.

Two, background technology

At present, known mechanical code lock has push-button type and dial type etc., and the structure that has is complicated; An end that must be fixed in the place device that has is applicable to devices such as door, case, cabinet, but it is inapplicable that wheel, steering wheel are not had the device of fixed attachments.

Three, summary of the invention

In order to overcome the deficiency of existing machinery coded lock, the present invention provides a kind of simple in structure, easy to use, rolling type mechanical coded lock that cost is low.

The technical solution adopted for the present invention to solve the technical problems is: it comprises rolling type mechanical coded lock shell, spring, location trace, password circle, changes a yard circle, steel ball, inner sleeve, outer tube, stud shaft, mills formations such as mouth, password circle steel ball hole.It is characterized in that in the lock shell, being provided with a stud shaft; But move left and right; The outer end of stud shaft is provided with bayonet socket, makes its corresponding lock iron constitute the lockset of a sealing, is provided with spring in the other end; Stud shaft is provided with one group three or many equidistant steel ball holes, hole depth+inner sleeve wall thickness=diameter of the steel ball; Password circle inboard is provided with a steel ball hole (like Fig. 4), password circle hole depth+inner sleeve thickness=diameter of the steel ball; The password circle with change yard snare outside inner sleeve, install one between two password circles and change the sign indicating number circle, outer tube is fixed on outside the inner sleeve; The password circle is that axle rotates with the inner sleeve; The password circle and change gapped between the sign indicating number circle, password circle and inner sleeve between matched in clearance it can be rotated, shell is provided with one and mills mouth, mills mouthful length according to the required displacement decision of location trace; The location trace passes shell and is connected with stud shaft and fixes through milling mouth; Prevent that stud shaft from rolling, the location trace drives stud shaft and does left and right sides translation under external force.In order to change the password needs, change the sign indicating number circle by adorning one in the middle of between per two password circles, change on the sign indicating number circle and be carved with the password alignment line; Changing the sign indicating number circle is fixed on the inner sleeve by a hook bolt; Can unclamp a hook bolt during Change Password, rotation changes the sign indicating number circle, moves to reach through graduation mark to change a yard purpose.

Beneficial effect of the present invention, simple in structure, easy to use, the password circle is done scale unit with millimeter, and password combination quantity is big, is applicable to the device of no fixed attachments such as bicycle, electric motor car, motorcycle.

Five, the specific embodiment

Embodiment 1: to suppose three password circles is that spring 2 is put in the inner of example () installation process stud shaft; Put into stud shaft 9 again; Location trace 3 passes shell and is fixedly connected with stud shaft 9 through milling mouthfuls 10, under the tension force effect of spring 2, locatees trace 3 and is positioned at as on Fig. 1 position; On the stud shaft 9 align with every steel ball hole on the inner sleeve just in every steel ball hole at this moment; Steel ball 6 is put into from inner sleeve steel ball hole, and steel ball 6 bottoms are just in time dropped in the steel ball hole on the stud shaft 9, and steel ball 6 tops are just in time equal with inner sleeve 7 outer walls.(diameter of the steel ball=inner sleeve wall thickness+stud shaft steel ball hole depth) is inserted in first password circle 4 from inner sleeve 7, and password circle 4 inwalls are pushed down steel ball 6; Steel ball 6 can not be moved, stud shaft 9 by steel ball 6 block can not about move, form to close the lock state; Be inserted in successively and change sign indicating number circle 5, change sign indicating number circle 5 usefulness and prop up sieve bolt and be fixed on the inner sleeve 7, be inserted in some groups of password circles 4 more successively; After changing sign indicating number circle 5, be inserted in outer tube 8 at last, outer tube 8 is fixed on the inner sleeve.(2) use: like Fig. 2 unlocking condition: behind password circle 4 rotary alignment passwords; Lock is in Fig. 3 state; Pulling location trace 3 is moved to the left, and steel ball 6 promptly slides in inner sleeve steel ball hole and the password circle steel ball hole 11, and stud shaft 9 can become unlocking condition to left.Like Fig. 1 closed condition: unclamp location trace 3; Stud shaft 9 is reset to Fig. 3 state under the effect of spring 2 tension force, rotational password circle 4; Steel ball 6 just rolls out in the steel ball hole of slipping on the inner sleeve in the inboard steel ball of password circle hole 11 and the steel ball hole on the stud shaft; Steel ball is pushed down in password circle inboard, makes the stud shaft can not translation, becomes closed condition.

Embodiment 2: suppose that with 5 or many password circles be example, below in conjunction with accompanying drawing practical implementation process of the present invention is described further:

(1) installation process: identical with embodiment 1.

(2) use: identical with embodiment 1.

All from now on this patent protection domains of conflicting that is regarded as that on stud shaft, is provided with more than one group equidistant code-locked tooth, password circle.
