Description

Multi-stage combined lock

The utility model relates to lock.

Existing lock is no matter be that bright lock or built-in lock are all opened different locks with different keys.This lock must be taken several keys with several locks, how has locked the trouble that just causes by bunch of keys.

Task of the present utility model provides a kind of combination lock, drives many locks belonging to me (comprising communal lock and special-purpose lock) with a key, reduce as far as possible people with the quantity of key, thereby reach purpose easily.

With the level Four combination lock is example, and the utility model comprises the increase and decrease pellet shot from a slingshot that lock cylinder 1, key 2, tapered end 3, increase and decrease pellet shot from a slingshot 4,5,6,7(can have quantity not wait according to the rank of combination lock), spring 8(only indicates an explanation), hat type pellet shot from a slingshot 9, fixedly pellet shot from a slingshot 10, tapered end pellet shot from a slingshot passage 11, lock cylinder pellet shot from a slingshot passage 12.Fixedly pellet shot from a slingshot is directly to contact with the tooth mouth of key, all changeless pellet shot from a slingshot in each lock in combination lock.The hat type pellet shot from a slingshot is a pellet shot from a slingshot that cap is arranged, and can not drop out the pellet shot from a slingshot passage of tapered end fully.Specification requirement of the present utility model is big unlike present universal latch specification, but the key of multistage combination lock will widen, and make key again energy is unimpeded in lock the pellet shot from a slingshot total length in the trajectory will enough be lacked.The pellet shot from a slingshot total length can't exceed the length of lock cylinder pellet shot from a slingshot passage sometimes for conforming with enough weak points, and makes the pellet shot from a slingshot forfeiture hinder the effect that lock cylinder rotates.The trajectory that the hat type pellet shot from a slingshot of for this reason packing in the tapered end trajectory of combination lock makes it not exclusively drop out tapered end is very important, and is different with present lock.The increase and decrease pellet shot from a slingshot is that the lock that has needs it in a cover combination lock, and the lock that has must remove it.

Operating principle of the present utility model is that example is described as follows with the level Four combination lock: it is crucial adding the increase and decrease pellet shot from a slingshot in the utility model.In the level Four combination lock, one-level lock (being the minimum lock of rank) need be established four increase and decrease pellets shot from a slingshot 4,5,6,7, reduce by an increase and decrease pellet shot from a slingshot 4 than the one-level lock in the secondary latch, simultaneously, on the basis of one-level key, the tooth mouth of the increase and decrease pellet shot from a slingshot 4 pairing secondary keys that cut improves than the tooth mouth of its corresponding one-level key, and the height of raising is the height of increase and decrease pellet shot from a slingshot 4.The secondary key can be opened secondary latch like this, also can drive the one-level lock, but the one-level key can not be opened secondary latch.

Three grades of locks reduce by two increase and decrease pellets shot from a slingshot 6,7 than secondary latch, simultaneously, on the basis of secondary key, the tooth mouth of increase and decrease pellet shot from a slingshot 6, the 7 pairing three grades of keys that cut improves than the tooth mouth of its corresponding one-level key, secondary key, and the height of raising is the height sum of increase and decrease pellet shot from a slingshot 6,7.Such three grades of keys can be driven one, two, three lock, and the I and II key is not driven three grades of locks.

The level Four lock lacks an increase and decrease pellet shot from a slingshot 5 than three grades of locks, increase an increase and decrease pellet shot from a slingshot 6 than three grades of locks simultaneously, simultaneously on the basis of three grades of keys, the increase and decrease pellet shot from a slingshot 5 pairing level Four key bit mouths that cut improve than the tooth mouth of one, two, three key of its correspondence, and the height of raising is the height of increase and decrease pellet shot from a slingshot 5.The level Four key can be driven the one, two, three, four lock like this, but one, two, three key can not be driven the level Four lock.

Increased increase and decrease pellet shot from a slingshot 6 again be in level Four lock in order to create three grades of keys arranged side by side again, second three grades of keys can only open one, two, the level Four lock, but can not drive three grades of locks.For distinguishing them, three grades of keys can driving three grades of locks are called three a level keys, three grades of keys can driving the level Four lock are called three b level keys.

Three b level keys are to change to some extent on the basis of level Four key, its tooth mouth that is not both increase and decrease pellet shot from a slingshot 6 pairing three b level keys descends than increase and decrease pellet shot from a slingshot 6 pairing level Four key bit mouths, the distance that descends is the height of increase and decrease pellet shot from a slingshot 6, such three b level keys can open one, two, the level Four lock, and can not drive three grades of locks.

The utility model is simple in structure, and is easy to manufacture, easy to use, security personnel's better performances.Promptly removed the trouble of people, solved the problem of several people's communal lock again well with special-purpose lock with bunch of keys.

It is example with the level Four combination lock that the utility model has following accompanying drawing).

Fig. 1 opens the sectional drawing of one-level lock for the one-level key.

Fig. 2 opens the sectional drawing of secondary latch for the secondary key.

Fig. 3 is the sectional drawing that three grades of keys are driven three grades of locks.

Fig. 4 opens the sectional drawing of level Four lock for the level Four key.

Fig. 5 is the sectional drawing that three b level keys are driven the level Four lock.

Below in conjunction with example and accompanying drawing the utility model is explained detailedly.

The utility model promptly is applicable to the lock of same specification, also is applicable to the lock of different size, and being locked in the manufacturing of same specification is very simple, can produce multistage combination lock easily as required.Now, select a cover level Four combination lock for use, the lock of existing same specification, the lock that different size is arranged again are that example is illustrated.

Shown in accompanying drawing, Fig. 1 is an access door built-in lock specification, partly form by L part and m, no matter the L part is that the specification or the specification of lock cylinder of tapered end all is present common access door built-in lock specification, but m partly has only the specification of tapered end identical with the specification of present being seen access door built-in lock, and the specification of lock cylinder is the specification (opening section that refers to bicycle lock) of present being seen cabinet door built-in lock, drawer built-in lock and bicycle lock.Fig. 2, Fig. 3, Fig. 4 are the specifications of now common cabinet door built-in lock, drawer built-in lock, bicycle lock, be that lock cylinder among m part lock cylinder among Fig. 1 and Fig. 2, Fig. 3, Fig. 4 is same specification, in order to connect them, just the tapered end of m part among Fig. 1 has been strengthened.

Among Fig. 1, the composition of one-level lock is: 6 in lock cylinder 1, key 2, tapered end 3, increase and decrease pellet shot from a slingshot 4,5,6,7,6 on spring, hat type pellet shot from a slingshot 6 (all in the pellet shot from a slingshot passage of tapered end), trajectory.In these 6 trajectories, tapered end trajectory diameter is bigger slightly than lock cylinder trajectory diameter, and the tapered end trajectory is bevel-type with section diameter that the lock cylinder trajectory soon contacts and dwindles, and is identical with lock cylinder trajectory diameter when arriving the edge.

The composition of secondary latch has deducted the L part in the one-level lock among Fig. 2, and the specification of m part tapered end also dwindles, but the lock cylinder specification is constant.In addition, removed increase and decrease pellet shot from a slingshot 4 in the secondary latch, for opening secondary latch, the increase and decrease pellet shot from a slingshot 4 pairing secondary key bit mouths that deduct have promoted, and the height of lifting is the height of increase and decrease pellet shot from a slingshot 4, when the secondary key is driven the one-level lock, increase and decrease pellet shot from a slingshot 4 is headed in the pellet shot from a slingshot passage of tapered end and open, and the one-level key can not head into pairing hat type pellet shot from a slingshot in the pellet shot from a slingshot passage of tapered end fully because of having deducted the height that increases and decreases pellet shot from a slingshot 4 when inserting in the secondary latch, also just can not open secondary latch.

Fig. 3 has deducted increase and decrease pellet shot from a slingshot 6,7 on the basis that three grades are locked in secondary latch, and makes increase and decrease pellet shot from a slingshot 6, the 7 pairing three a level key bit mouths that deduct improve the height of increase and decrease pellet shot from a slingshot 6,7 sums.Three a level keys are opened one-level when lock, increase and decrease pellet shot from a slingshot 4,6,7 is headed into fully in the pellet shot from a slingshot passage of tapered end and the one-level lock is opened; To increase and decrease pellet shot from a slingshot 6,7 when opening secondary latch heads into fully in the pellet shot from a slingshot passage of tapered end and secondary latch is opened.And the I and II key can not head into the hat type pellet shot from a slingshot in the pellet shot from a slingshot passage of tapered end when inserting in three grades of locks fully, does not also just drive three grades of locks.

Fig. 4, level Four is locked on the basis of three grades of locks has removed increase and decrease pellet shot from a slingshot 5, and has increased increase and decrease pellet shot from a slingshot 6 again, and the increase and decrease pellet shot from a slingshot 5 pairing level Four key bit mouths that deduct have been promoted, and highly is the height of increase and decrease pellet shot from a slingshot 5.The level Four key is opened one-level when lock, increase and decrease pellet shot from a slingshot 4,5,6,7 is headed into fully in the pellet shot from a slingshot passage of tapered end and opens; To increase and decrease pellet shot from a slingshot 5,6,7 when opening secondary latch heads into fully in the pellet shot from a slingshot passage of tapered end and opens; Open three grades of whens lock, will increase and decrease pellet shot from a slingshot 5, to head into tapered end pellet shot from a slingshot passage fully interior and open.And one, two, three key is not all driven the level Four lock.

Fig. 5, three b level keys are on the basis of level Four key, and increase and decrease pellet shot from a slingshot 6 pairing tooth mouths are descended, the distance of decline is the height of increase and decrease pellet shot from a slingshot 6.Three b level keys are opened one-level when lock, will increases and decreases pellet shot from a slingshot 4,5,7 and head into fully in the tapered end pellet shot from a slingshot passage and open, increase and decrease pellet shot from a slingshot 6 at this moment not headed in the tapered end pellet shot from a slingshot passage, and in lock cylinder; When opening secondary latch, increase and decrease pellet shot from a slingshot 5,7 is headed into fully in the tapered end pellet shot from a slingshot passage and is opened, and increase and decrease pellet shot from a slingshot 6 is stayed in the lock cylinder; Opening level Four when lock, increase and decrease pellet shot from a slingshot 6 is stayed in the lock cylinder, and corresponding hat type pellet shot from a slingshot is headed into fully in the pellet shot from a slingshot passage of tapered end and open; When three b level keys insert in three grades of locks, because of just not opening in the pellet shot from a slingshot passage that increase and decrease pellet shot from a slingshot 6, the 7 pairing hat type pellets shot from a slingshot that are removed can not be headed into fully tapered end.

In this example, can suppose to lock as the access door built-in lock with the one-level among Fig. 1, the secondary latch among Fig. 2 is as cabinet door built-in lock, and three grades of locks among Fig. 3 are as the drawer built-in lock, and the level Four lock among Fig. 4 is as bicycle lock.First people need drive a lock, and so, first people gets final product the one-level key by one; Second people need drive three locks, and so, second people only takes one three a level keys; Third people need drive four locks, and third people only takes one the level Four key.If second, the third two people need respectively have a special-purpose lock, so, second people can take one three a level keys, third people by one three b level keys.

Here be the example explanation with the level Four combination lock, in actual applications, people may use secondary combination lock, three grades of combination lock, also may use Pyatyi, six grades of combination lock, as long as required the quantity that increases and decreases pellet shot from a slingshot is controlled, just can create.No matter bright lock, built-in lock can.
