Description of drawings
Shown in Figure 1, be the utility model sectional structure schematic diagram.
Shown in Figure 2, be the right view of Fig. 1.
The specific embodiment
Below, in conjunction with the accompanying drawings, the utility model is described in further detail.
In the right view of the structural representation of Fig. 1 and Fig. 2 as can be known, this lock core comprise lock core body 1, rotor cover 2, rotor 5, down pellet shot from a slingshot 11, middle pellet shot from a slingshot 14, go up pellet shot from a slingshot 15 and spring 17.Wherein, in Fig. 2, dialled key 10.Left end head at rotor cover 2 is provided with tabular shifting block 3, is used to stir dead bolt or snap close.The projection 7 of lock core body 1 left end inboard by several symmetries be located at groove 6 that rotor overlaps 2 left end corresponding position ring-types movingly, rotor cover 2 can be located in the lock core body 1, and can rotate 360 ° flexibly.In like manner, rotor overlaps the projection 8 of 2 endoporus left ends by several symmetries and the annular recess 9 that is located at rotor 5 left end corresponding positions movingly, rotor 5 can be located in the rotor cover 2, and can rotate 360 ° flexibly.This is the prior art common structure of lock core body and rotor.In the corresponding position of lock core body 1, rotor cover 2 and rotor 5, all corresponding several pellets shot from a slingshot hole that is provided with, each pellet shot from a slingshot hole can be divided and be set as columniform pellet shot from a slingshot hole 16, middle shell hole 13 and the lower marble hole 12 gone up.Wherein, the lower end in last pellet shot from a slingshot hole 16 is provided with pellet shot from a slingshot 15, and the upper end is provided with marble spring 17, and the upper port in last pellet shot from a slingshot hole 16 is provided with chock 18, prevents freely withdrawing from of spring 17.The equal in length of pellet shot from a slingshot 15 on each.Middle pellet shot from a slingshot hole 13 is the little down big shoulder hole of, wherein be provided with the cylindrical middle pellet shot from a slingshot 14 of respective steps, pellet shot from a slingshot 14 big or small cylinders length partly can be unequal in each, the total length of two parts also can be unequal, and extending to cover, the length of pellet shot from a slingshot 14 is provided with according to cooperating with the tooth of key 10 in each.The diameter of the small end head of the aperture of lower marble hole 12 and middle pellet shot from a slingshot 14 and following pellet shot from a slingshot 11 is corresponding, the equal in length of each time pellet shot from a slingshot 11 also equals the upper wall thickness of rotor, but, cooperating with the tooth depth of key 10 length low and middle pellet shot from a slingshot 14, its length of stretching out keyhole 4 can be different.Each upper, middle and lower pellet shot from a slingshot all can be gone here and there moving in its pellet shot from a slingshot hole, place.In Fig. 1, the key 10 of coupling is inserted in the keyhole 4.
