Description

Swing type lock core lock

Technical field

The utility model relates to lockset, and being specially a kind of lock core can shuttle-type swing type lock core lock.

Background technology

At present, lockset commonly used is the rotary type cylinder lock, when the key of correspondence inserts in the lockhole of corresponding lockset, as shown in Figure 1a, pellet shot from a slingshot 11 in tooth on the key and the lock core contacts, make flat pellet shot from a slingshot and buckshot just be in the bonding surface place of lock core and lock body, rotational lock core 12 can drive corresponding mechanism, thereby lock is opened.

When the key of insertion lockhole was not corresponding with lockset, shown in Fig. 1 b, the bonding surface of lock core and lock body was lived by flat pellet shot from a slingshot or buckshot subcard, makes lock core 12 to rotate relative to lock body, then lock can not be opened.

But this kind lock is to be changed to reciprocating motion to rotatablely move, and then reaches switching purposes; But it also has certain limitation in some occasion, and such as not possessing in the mechanism that rotatablely moves at some, the lock of this kind rotary locking cylinder formula possibly can't be installed, after perhaps installing, move dumb, interlocking mechanism complexity, switch inconvenience.

The utility model content

The technical problem that the utility model solved is to provide a kind of swing type lock core tool, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solved realizes by the following technical solutions:

Swing type lock core lock, comprise lock body, be installed in the lock core in the lock body, offer keyhole on the described lock core, on described lock body and lock core, offer some corresponding pellets shot from a slingshot hole separately, in some pellets shot from a slingshot hole of described lock core, be equipped with highly different and expose buckshot of described keyhole, the flat pellet shot from a slingshot and the spring of setting height(from bottom) unanimity in some pellets shot from a slingshot hole of described lock body, it is characterized in that, be connected by a rotating shaft between described lock core and the lock body, described lock core rotates in lock body around described rotating shaft.

In order to limit the rotational angle of lock core, offering one on described lock body is the circular-arc locating hole in the center of circle with described rotating shaft, and described lock core is provided with an alignment pin that inserts in the described circular-arc locating hole.

In the utility model, the bottom in the pellet shot from a slingshot hole of described lock body covers by the cover plate that is fixed on the lock body.

In the utility model, the sub-head of described buckshot is a taper surface, and the bottom is the cylinder on a plane; Described flat pellet shot from a slingshot is that a upper and lower surface is the cylinder on plane,

On lock core of the present utility model, also be provided with in order to drive the dead bolt of lockset action.

Using method of the present utility model is as follows:

The key of correspondence is inserted in the lockhole of corresponding swing type lock core lock, each buckshot and pit on the key match, make each buckshot place the pellet shot from a slingshot hole of lock core fully, and flat pellet shot from a slingshot places the pellet shot from a slingshot hole of lock body fully, make the bonding surface of the peaceful pellet shot from a slingshot of buckshot just in time be in the bonding surface place between lock core and the lock body like this, the swing key drives the lock core swing, drive the lockset action by the dead bolt on the lock core, realize unblanking.The hunting range of alignment pin of the present utility model and locating hole restriction lock core.If the lockhole of key and swing type lock core lock is not at once, then as long as any one buckshot and pit on the key do not match, the bonding surface that so just has a peaceful pellet shot from a slingshot of any one group of buckshot is not just in time aimed at the bonding surface between lock core and the lock body, lock core is subjected to stopping of buckshot or flat pellet shot from a slingshot, just can't swing and realize unblanking.

Beneficial effect: the utility model is simple in structure, and it is convenient to open, the safety that has improved lockset.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5 swing type lock core lock comprises lock core 1, lock body 2, key 0, and present embodiment is the embodiment that corresponding key 0 inserts the lockhole of corresponding lockset lock core 1.

Lock core 1 is installed in the lock body 2, on lock core 1, offer keyhole 11, on lock body 2 and lock core 1, offer some corresponding pellets shot from a slingshot hole 12,21 separately, in some pellets shot from a slingshot hole 12 of lock core 1, be equipped with highly different and expose buckshot 61 of keyhole 11, the flat pellet shot from a slingshot 62 and the spring 63 of setting height(from bottom) unanimity in some pellets shot from a slingshot hole 21 of lock body 2, be connected by a rotating shaft 3 between lock core 1 and the lock body 2, lock core 13 rotates in lock body 2 around the shaft.Lock core 1 is placed in the lock body 2 for cuboid.In order to limit the rotational angle of lock core 1, offering one on lock body 1 is the circular-arc locating hole 4 in the center of circle with rotating shaft 3, and lock core 1 is provided with an alignment pin 5 that inserts in the circular-arc locating hole 4.The bottom in the pellet shot from a slingshot hole 21 of lock body 2 covers by the cover plate 7 that is fixed on the lock body 2.Buckshot 61 heads are a taper surface, and the bottom is the cylinder on a plane; Flat pellet shot from a slingshot 62 is that a upper and lower surface is the cylinder on plane.On lock core 1, also be provided with in order to drive the dead bolt 13 of lockset action.
