The specific embodiment

For making content of the present utility model clearer, understandable,, the lock core with dust reduction capability of the present utility model is elaborated by specific embodiment below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, Fig. 3, the lock core with dust reduction capability in the present embodiment comprises core body 1, is arranged on dustproof door 2 on the core body 1, is arranged on the dust cap 4 on the dustproof door 2, and the lock housing 3 that core body 1 is coated, and the top of lock housing 3 also is provided with dustproof fence 5.Wherein, core body 1 middle part longitudinally is provided with keyhole 11, and core body 1 periphery is provided with a plurality of locking plates hole 12, is provided with two locking plates in each locking plate hole 12.

Wherein, dustproof door 2 comprises an

opposite house body

21,22, and with the back-moving spring 21a of door body 21 butts and the back-moving spring 22a of door body 22 butts.Referring to Fig. 2, Fig. 4, the below of door body 21 is provided with slide block 21b, and the below of door body 22 is provided with slide block 22b, referring to Fig. 3, relevant position on the core body 1 is provided with chute 1a, 1b, and slide block 21b stretches among the chute 1a and can slide in chute 1a, and slide block 22b stretches among the chute 1b and therein slidably.By on the door body, establishing slide block, chute is set on core body, by cooperating of slide block and chute, make the door body on core body, can stablize when mobile and carry out, be unlikely skew.Referring to Fig. 5, door body 21 and door body 22 sides adjacent are the inclined-plane, make to form a groove 2a when the two is docking together.When unblanking, key can act on this groove 2a, makes each inclined-plane be subjected to horizontal promotion component, makes door body 21 and door body 22 separate, and keyhole 11 is exposed.

Wherein, also be provided with a dust cap 4 on the dustproof door 2, referring to Fig. 6, the gusset body 42 that this dust cap 4 comprises lid 41 and is arranged on lid 41 belows, lid 41 is provided with keyhole 41a.Dust cap 4 covers on the dustproof door 2, and keyhole 41a makes the joint of an opposite house body expose.

Wherein, dustproof fence 5 comprises top cover with through hole and following the enclosing that is connected with the top cover edge.

Wherein, referring to Fig. 3, the bottom of core body 1 also is provided with a dedusting groove 13, these dedusting groove 13 1 ends and keyhole 11 conductings, the other end and outside conducting.This dedusting groove 13 is set, even make have dust to fall into keyhole, after key inserted in the keyhole, dust can enter into dedusting groove 13 from keyhole, then is discharged to the keyhole outside.

Lock core in the present embodiment with dust reduction capability, dustproof door is not when being subjected to external force, door contacts between the body, lockhole is hidden, in order to avoid the entering of dust, foreign matter, water, in the time will opening, only need key is inserted to dustproof door, the stressed back of door body naturally separately makes keyhole expose, key inserts in the keyhole, opens lock core; After key was extracted, the door body was got back to the origin-location under the effect of back-moving spring separately, and two door bodies dock once more, and keyhole is hidden.Lock core in the present embodiment with dust reduction capability, dustproof door is set can blocks dust, foreign matter, water enter in the keyhole, and open, simple to operate during closed dustproof door, need not to carry out extra action, therefore easy to use, can prolong application life of lock core.
