Description

Code multidigit mechanical code lock

The utility model relates to a kind of engineering goods, relates in particular to a kind of code multidigit mechanical code lock that is used for door, window, reaches safety cabinet and so on.

At present, the coded lock of selling on the market, of a great variety, code and code are not arranged, code is locked most complex structure, and the cost height is difficult for promoting.

The purpose of this utility model provides a kind of simple in structure, and is cheap, easy to use, strong security deceive a yard multidigit mechanical code lock.

The technical solution of the utility model realizes in the following manner:

A kind of code multidigit mechanical code lock, it comprises lock body, one lock shaft is arranged, be placed in lock body with the lock body sliding-contact, lock shaft has interior wheel outward, interior wheel inwall has an axial keyway, having on the lock shaft can be by the key of keyway, being with foreign steamer, foreign steamer and interior wheel outside the interior wheel meshing by axial teeth groove is one, interior wheel, foreign steamer overcoat one adjusting ring, adjusting ring one side bag is buckled on the foreign steamer, positioning spline is arranged on the lock body, spring is arranged in the keyway, there is pellet shot from a slingshot on the top on the spring, wheel endwisely slipped with prevention in pellet shot from a slingshot held out against, and the writing of two rows from 1-10 numbers arranged on the foreign steamer.

Lock body is half Cylinder, and lock shaft is half Cylinder, and lock body, lock shaft are formed a Cylinder.

The interior wheel that is placed in outside lock shaft, the lock body is 1-l0, and the foreign steamer meshing with foreign steamer is 1-10.

Good effect of the present utility model is:

Simple in structure, volume is little, and is easy to use, and encode at any time, decode, antitheft, strong security, cost is low, is easy to promote.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation that partly cuts open of the present utility model.

Fig. 2 is the cross-sectional view of Fig. 1 along A-A direction.

By Fig. 1-Fig. 2 as can be seen, half garden post lock body 2 is arranged in the middle of the utility model, with lock body 2 sliding-contacts half Cylinder lock shaft 1 is arranged, lock body, lock shaft is formed a Cylinder, be placed in lock body 2, wheel 3 in one is arranged outside the lock shaft 1, interior wheel 3 inwalls have an axial keyway, the key that matches with keyway is arranged on the lock shaft 1, the interior wheel 3 outer foreign steamers 4 that are with, foreign steamer 3 is meshing by axial teeth groove with interior wheel 4 to be one, interior wheel 3, foreign steamer 4 overcoats one adjusting ring 6, adjusting ring 6 one side bags are buckled on the foreign steamer 4, take turns on 3 in opposite side is wrapped in, outside foreign steamer 4 is exposed to through adjusting ring, on the lock body 2 positioning spline is arranged, spring is arranged in the keyway, on the spring top have pellet shot from a slingshot, pellet shot from a slingshot hold out against in wheel 3 to stop it to endwisely slip, the writings of two rows from 1-10 numbers are arranged on the foreign steamer 4.As seen from Figure 1, being placed in lock shaft 1, lock body 2 outer interior wheels 3 is four, and the foreign steamer 4 meshing with foreign steamer 3 also is four; Interior wheel 3 sections are hilt shape, and when wheel 3 rotated in foreign steamer 4 drives, the key on the lock shaft 1 contacted with hilt.

During use, rotate foreign steamer 4 by predefined password, wheel 3 rotated in foreign steamer 4 drove, the keyway of wheel 3 inwalls is aimed at the key on the lock shaft in making, and then lock shaft can withdraw from by moving axially, and lock is promptly opened, as lock not being locked immediately, then can be rotated further foreign steamer 4, wheel 3 in driving upsets password in case there is the people to snatch password.When locking a door again, the keyway of wheel 3 was aimed at the key on the lock shaft in the password when opening rotated and makes, and at this moment, lock shaft can advance again, promptly pins.Rotate foreign steamer 4 then immediately, wheel 3 in driving makes that password is upset, key misplaces with keyway, does not know that in such cases the people of password just is difficult to open.

When the needs recompile, can promote adjusting ring 6, driving foreign steamer 4 moves axially, make foreign steamer 4 and interior wheel 3 separating tooth positions, rotate foreign steamer 4 then, meshing with interior wheel 3 again again after the number of the internal wheel key way on the foreign steamer is changed, the password when then unblanking obtains change, and the password after the change can be upset immediately in order to avoid give away secrets.
