Abstract

The utility model relates to a rolling type mechanical coded lock which is technically characterized in that a stud shaft is arranged in the center of the casing 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, a group of steel ball holes (three or more) are arranged on the stud shaft at equal intervals, coded rings and code-changing rings are sleeved outside an inner sleeve pipe, one code-changing ring is installed between the two coded rings, a milling opening is also arranged on the casing, a positioning and interlocking rod drives the stud shaft to move left and right under the action of external force, and the rolling type mechanical coded lock can achieve purposes of opening and closing. The utility model has the advantages of simple structure, low cost, convenient use, and the like, and is suitable for devices without a fixed attachment, such as bicycles, motorcycles, electric vehicles, and the like.

Description

Rolling type mechanical coded lock

One, technical field

The utility model relates to a kind of lockset by unlock password, especially refers to rotate the rolling type mechanical coded lock of the mode release of password circle.

Two, background technology

At present, known mechanical code lock has by of bonding 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 utility model provides a kind of simple in structure, easy to use, rolling type mechanical coded lock that cost is low.

The technical scheme that its technical problem that solves the utility model adopts 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, make its corresponding lock iron constitute the lockset of a sealing, be 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 (as 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, mill mouthful length according to the required displacement decision of location trace, the location trace mouthful passes shell and stud shaft is connected and fixed by milling, 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 by graduation mark to change a yard purpose.

The beneficial effects of the utility model, 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 fixedlys connected with stud shaft (9) by milling mouthful (10), under the tension force effect of spring (2), location trace (3) is positioned at as on Fig. 1 position, align just with every steel ball hole on the inner sleeve in the steel ball hole that stud shaft this moment (9) is last every, steel ball (6) is put into from inner sleeve steel ball hole, just in time drop on bottom the steel ball (6) in the steel ball hole on the stud shaft (9), steel ball (6) top is just in time equal with inner sleeve (7) outer wall.(diameter of the steel ball two inner sleeves wall thickness+stud shaft steel ball hole depth), be inserted in first password circle (4) from inner sleeve (7), password circle (4) inwall is pushed down steel ball (6), steel ball (6) can not be moved, stud shaft (9) by steel ball (6) block can not about move, formation shuts state, be inserted in successively and change sign indicating number circle (5), changing sign indicating number circle (5) is fixed on the inner sleeve (7) with sieve bolt, 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: as 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.As Fig. 1 closed condition: unclamp location trace (3), stud shaft (9) is under the effect of spring (2) tension force, be reset to Fig. 3 state, rotational password circle (4), steel ball (6) just rolls out the inboard steel ball hole of password circle (11) and slips in the steel ball hole and the steel ball hole on the stud shaft on the inner sleeve, 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 the utility model specific implementation process 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 considered as that on stud shaft, is provided with more than one group equidistant code-locked tooth, password circle.
