Abstract

The utility model relates to a meshing type mechanical coded lock which is technically characterized in that a stud shaft is arranged in the center of a casing of the coded 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 (three or more) cold locking teeth are arranged on the stud shaft at equal intervals, a coded ring is arranged in the casing and corresponds to the cold locking teeth, a milling opening is also arranged on the casing, a positioning and interlocking rod penetrates through the casing through the milling opening and is fixedly connected with the stud shaft, and the positioning and interlocking rod drives the stud shaft to move left and right under the action of external force so that the cold locking teeth on the stud shaft are sleeved in the tooth hole of the coded ring to achieve the purpose of unlocking or locking. The utility model has simple structure, low cost and convenient use and is suitable for devices without a fixed attachment, such as bicycles, motorcycles, electric vehicles, and the like.

Description

Engagement type mechanical code lock

One, technical field

The utility model relates to a kind of lockset by unlock password, especially refers to the engagement type mechanical code lock by the mode release of rotation 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, engagement type mechanical code lock that cost is low.

The technical scheme that its technical problem that solves the utility model adopts is: engagement type mechanical code lock comprises: shell, the location trace, the password circle, the code-locked tooth, spring, stud shaft, mill mouth, formations such as password circle perforation, it is characterized in that: the shell center of coded lock is provided with stud shaft, but move left and right, the outer end of stud shaft is provided with bayonet socket, make coupled lock iron constitute the circular lock of a sealing, the inner of stud shaft is provided with spring, on stud shaft, be provided with one group three or many equidistant code-locked teeth, the password circle is located in the shell and the corresponding installation of code-locked tooth, the inboard of password circle is provided with perforation, between password circle and the stud shaft, leaving the gap between password circle and the code-locked tooth can rotate it just, on shell, establish one and mill mouth, the location trace mouthful passes shell and fixedlys connected with stud shaft by milling, prevent that stud shaft from rolling, the location trace drives stud shaft and does a left side under the effect of external force, right translation.Be carved with the password alignment line on the shell on coded lock both sides, behind password circle rotary alignment password, perforation is tackled every code-locked tooth on the accurate stud shaft in every password circle, this moment stud shaft the location trace drive under to left, code-locked tooth on the stud shaft is inserted in the perforation of password circle, as shown in Figure 2, reach the purpose of unblanking, unclamp the location trace, stud shaft moves right stud shaft under the effect of spring tension, at this moment, and the rotational password circle, password circle perforation and code-locked tooth are staggered, and lock is in closed condition.

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 that the device of no fixed attachments such as bicycle, electric motor car, mill holder car uses.

Four, description of drawings

Fig. 1 is an engagement mechanical code lock closed condition vertical section constructional drawing.

Fig. 2 is an engagement type mechanical code lock opening vertical section constructional drawing.

Fig. 3 is a password coil structures schematic diagram.

1. shells among the figure; 2. location trace; 3. password circle; 4. code-locked tooth; 5. stud shaft; 6. spring; 7. mill mouth; 8. password circle perforation.

Five, the specific embodiment

Embodiment 1: suppose that three password circles are example, below in conjunction with accompanying drawing the utility model specific implementation process is described further: (one) installation process: spring (6) is put in shell (1) the inner, stud shaft (5) passes every perforation (8) in the password circle successively and packs in the shell (1), it is fixing with stud shaft (5) that location trace (2) passes shell (1), location trace (2) left and right sides translation under the effect of spring (6) tension force.

(2) use: unlocking condition: the shell on coded lock both sides is carved with the password alignment line on (1), rotate by password circle (3), after aiming at password, perforation (8) should be aimed at every the code-locked tooth (4) on the stud shaft (5) in every password circle, stud shaft this moment (5) is inserted in the perforation of password circle the code-locked tooth on the stud shaft to left under the drive of location trace (2), reaches unlocking condition.(as Fig. 2) closed condition: unclamp location trace (2), stud shaft (5) is reset to Fig. 1 position under the effect of spring (6) tension force, and at this moment, rotational password circle (3) staggers password circle perforation (8) and code-locked tooth (4), and lock is in 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 stud shaft, be provided with more than one group equidistant code-locked tooth, password circle be considered as conflicting in this patent protection domain.

Claims

1, engagement type mechanical code lock, comprise shell (1), location trace (2), password circle (3), code-locked tooth (4), stud shaft (5), spring (6), interior perforation (7), the shell center that it is characterized in that coded lock is provided with stud shaft (5), the outer end of stud shaft is provided with bayonet socket, the inner of stud shaft (5) is provided with spring (6), on stud shaft (5), be provided with one group three or many equidistant code-locked teeth (4), password circle (3) is located in the shell (1) and the corresponding installation of code-locked tooth, also be provided with one and mill mouthful (7) on shell, location trace (2) mouthful passes shell (1) and fixedlys connected with stud shaft (5) by milling.

2, by the described engagement type mechanical code lock of claim 1, it is characterized in that described password coil structures password circle inboard is provided with interior perforation (7).
