Description
Technical field
The utility model relates to a kind of lockset, relates in particular to a kind of high security lock core device.
Background technology
Lock core device of the prior art, comprise lock core body and lock core rotary body, lock core rotary body is arranged in lock core body and is rotatably assorted with lock core body, one side of lock core body is provided with circular hole in multiple lock core bodies, the lock core a rotating body circular hole that lock core rotary body is provided with a row and equates with lock core body inner circle hole number, in rotation process, lock core a rotating body circular hole can be corresponding one by one with circular hole in lock core body in lock core body for lock core rotary body.In lock core body, in circular hole, be provided with the interior pellet of buckshot, spring and lock core body, buckshot is fixed in the interior circular hole of lock core body and near port, and one end of spring is pressed on buckshot, and the other end of spring is pressed on the interior pellet of lock core body; In each lock core a rotating body circular hole, be provided with the lock core a rotating body pellet of different length.
The operating principle of this lock core device is: in the time that key does not insert lock core a rotating body, because pellet in the effect lock core body of spring moves downward in lock core a rotating body circular hole, until contact with lock core a rotating body pellet, by stuck relative lock core rotary body lock core body, lock core rotary body cannot rotate.Due to the control of length, in lock core body, a part for pellet is in lock core a rotating body circular hole, and a part in circular hole, reaches stuck effect in lock core body, and lock core rotary body cannot rotate, and reaches the effect of locking a door.In the time that key inserts lock core a rotating body, because height site on the key and the height of lock core a rotating body pellet are what prepare, in each lock core a rotating body pellet and each lock core body, pellet is (to be lock core body and lock core rotary body binding site) on same level line, lock core rotary body just can rotate so, reaches open door effect.
The equal and opposite in direction of pellet in all lock core bodies in lock core body of the prior art in circular hole, the length of buckshot and spring all equates, so the suffered dynamics of the interior pellet of lock core body, buckshot and spring too.Once be provided with on the key dynamics testing arrangement, just can record the length of all lock core a rotating body pellets at once, so just can allot the key opening the door at once; Setting pressure device on the key in addition, such as spring pressure device etc., equate with the pressure of the spring in circular hole in lock core body, the interior pellet of lock core body is on a horizon so, as long as at this time move up and down the pressure apparatus of a bit installing on the key to lock core body and lock core rotary body binding site, can reach open door effect, so this lock core device is dangerous.
Utility model content

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, high security lock core device, comprises lock core body 1 and lock core rotary body 2.Lock core rotary body 2 is arranged in lock core body 1 and is rotatably assorted with lock core body 1, and a side of lock core body 1 is provided with circular hole 3 in multiple lock core bodies, and in the present embodiment, a side of lock core body 1 is provided with circular hole 3 in three lock core bodies.The lock core a rotating body circular hole 4 that lock core rotary body 2 is provided with a row and equates with 3 quantity of circular hole in lock core body, also on lock core rotary body 2, be provided with three lock core a rotating body circular holes 4, lock core a rotating body circular hole 4 can be corresponding one by one with circular hole in lock core body 3 in the interior rotation process of lock core body 1 for lock core rotary body 2.In lock core body, in circular hole 3, be provided with pellet 7 in buckshot 5, spring 6 and lock core body, buckshot 5 is fixed on the interior also close port of circular hole 3 in lock core body, one end of spring 6 is pressed on buckshot 5, the other end of spring 6 is pressed on the interior pellet 7 of lock core body, and in lock core body, pellet 7 is slidably matched with the interior circular hole 3 of lock core body.In each lock core a rotating body circular hole 4, be provided with the lock core a rotating body pellet 8 of different length, lock core a rotating body pellet 8 is slidably matched with lock core a rotating body circular hole 4.Buckshot 5 in each lock core body in circular hole 3 in lock core body in the length in circular hole 3, lock core body the summation of the drift of the length of pellet 7 and spring 6 all unequal.
The overall length of buckshot 5 in each lock core body in circular hole 3, the interior pellet 7 of lock core body and spring 6 is all unequal, and its embodiment has multiple: embodiment one, the buckshot 5 length difference in circular hole 3 in lock core body in each lock core body in circular hole 3; Embodiment two, the length difference of pellet 7 in circular hole 3 internal lock core body in each lock core body; Embodiment three, the drift difference of the spring 6 in each lock core body in circular hole 3.
The diameter of lock core a rotating body pellet 8 is than the little 0.1～0.2mm of diameter of lock core a rotating body circular hole 4; In lock core body, the diameter of pellet 7 is than the little 0.1～0.2mm of the diameter of circular hole in lock core body 3, making has certain gap between circular hole 3 in pellet 7 and lock core body between lock core a rotating body pellet 8 and lock core a rotating body circular hole 4 and in lock core body, the pellet 7 interior slip of circular hole 3 in lock core body in lock core a rotating body circular hole 4 and in lock core body that is conducive to lock core a rotating body pellet 8.One end that in lock core body, pellet 7 is corresponding with lock core a rotating body pellet 8 and the two ends of lock core a rotating body pellet 8 arrange respectively the chamfering that R is 0.15～0.20mm, this chamfering is also conducive to lock core a rotating body pellet 8 in the 4 interior slips of lock core a rotating body circular hole, is also conducive to pellet 7 interior slip of circular hole 3 in lock core body in lock core body.
When key 9 inserts lock core rotary body 2 when interior, because the height site 10 on key 9 is what prepare with the height of lock core a rotating body pellet 8, in each lock core a rotating body pellet 8 and each lock core body, pellet 7 is on same level line (being lock core body and lock core rotary body binding site 11), lock core rotary body 2 just can rotate so, reaches open door effect.Due to buckshot 5 in circular hole 3 in each lock core body in lock core body in the length in circular hole 3, lock core body the summation of the drift of the length of pellet 7 and spring 6 all unequal, when key 9 inserts lock core rotary body 2 when interior, the power difference that spring 6 in lock core body 1 produces, even if be provided with dynamics testing arrangement on key 9, also cannot record the length of all lock core a rotating body pellets 7, also just cannot rely on other key to allot out this key, safety factor is higher.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
