Description

A kind of double permulation lock and key

The utility model relates to lock and key.

Chinese patent discloses a kind of check mark car plate for No. 90227218.7, and it inserts a plate on car plate, makes number on the common face of car plate and plate, and then board face number is imperfect to extract plate out.Surround lock core because the structure of conventional lock is a lock body again, promptly embed the lock core of a column in the lock body, key hole is arranged on the lock core, insert the rotatable lock core of key and unblank.If with plate is made as one and key one side surface also need be made number,, obviously can't adopt the mode of rotational lock core of routine to unblank key so that plate and lock board surface can be together to form a kind of special symbol.

The purpose of the utility model is to provide a kind of key one side surface that makes can constitute a lock board with surface of lock body is common, and key should be to the number of the board of locking, again to the double permulation lock and the key of last code-locked (pellet shot from a slingshot).

Double permulation lock described in the utility model, lock core and lock body are arranged side by side, spring in the lock core side opening, pellet shot from a slingshot in pellet shot from a slingshot and the lock body side opening is corresponding one by one, lock core marble protrudes to snap under the spring force effect and makes the relative lock body of lock core can not parallel slip in the lock body opening, lock body one side has the key slot, lock spring can protrude to slot, lock core is parallel with locking bolt, concave station is arranged on the lock core, have annular groove on the locking bolt, adorn vertical pin between lock core and the locking bolt, pin two ends slyness, can snap in respectively in the annular groove of the concave station of lock core or locking bolt, an end of lock core stretches out outside the housing, other end dress stage clip is executed axial force to it, the locking external part shock mount of locking bolt, when being in locking state, locking bolt is oppressed this spring.

With the key that described double permulation lock is used, the plate as lock board ingredient is arranged, the plate surface can make or paste digital symbol, and the plate opposite side protrudes a code-locked bar, on the code-locked bar key bit is arranged.

When lock described in the utility model was in locking state and does not promptly insert key, it is not removable that the pellet shot from a slingshot of lock core blocks lock body, and locking bolt stretches out the spring that compresses its opposite, and the annular groove that pin snaps in locking bolt can not retreat it; Insert key when unblanking, the pellet shot from a slingshot of the code-locked bar promotion lock body of key pushes up back the pellet shot from a slingshot of lock core, make lock core and lock body constraint relief, stretch out housing one end at lock core then and push lock core, lock core is moved, when the concave station of lock core moves to the pin place, the slyness end of pin snaps in and has promptly removed the thrust of the pin other end to the locking bolt annular groove in the concave station, and locking bolt ejects backward under the effect of spring axial force over there and unblanks.If locking once more promotes the locking bolt reach, make annular groove be in the pin place, pin snaps in the thrust of annular groove releasing to the lock core concave station, and under the spring force effect, lock core retreats to the position of the relative lock spring of each pellet shot from a slingshot, extracts key out, and lock core can not displacement, i.e. locking.Described lock ﹠ key, its key inserts and aligns code-locked, and because of unblank to need not to reverse key by movable lock core, then a side of key can constitute the lock board jointly with surface of lock body, and is convenient on whole lock board symbol such as making number.

The front view of the described lock of Fig. 1;

Fig. 2 lock body backsight structural representation, locking state;

Fig. 3 is the A-A view of Fig. 2;

Fig. 4 is the unlocking condition of Fig. 2;

Fig. 5 is the elevation of Fig. 2;

Fig. 6 is the stereogram of key.

Lock body 5 is fixed in the housing 2, lock body one side and housing front are at same plane B, lock core 4 is arranged side by side with lock body, and spring 11, pellet shot from a slingshot 12 in the lock core side opening are corresponding one by one with the pellet shot from a slingshot 13 of lock body side opening, and lock core marble can protrude and snaps in the lock body side opening and make the lock core 4 can not slippage.Key slot 14 is opened in lock body 5 sides, and lock spring 13 can protrude in the groove 14.Lock core 4 is parallel with locking bolt 10, and concave station 3 is arranged on the lock core 4, open loop groove 9 on the locking bolt 10, pin 8 perpendicular between the two and the pin two ends can snap in respectively in concave station 3 or the annular groove 9, pin 8 can be the two ends slyness, but as shown in Figure 2, it is better that the pin two ends dispose ball 7 results of use respectively.One end of lock core 4 stretches out outside the housing 2, other end dress stage clip 1, and shock mount 15 in the housing 2 of locking bolt 10 external parts makes locking bolt oppress this spring 15 when locking state.Key is the code-locked bar 16 that plate 6 one sides have protrusion, has a plurality of depths not wait with lock spring 13 corresponding pits 17 on the code-locked bar and constitutes key bit.
