Description
The present invention relates to a kind of theftproof lock, more particularly, it relates to close finger setting theftproof lock of a kind of spiral.
Background technology
The existing theftproof lock in market is arranged with sheet pin or pellet in lock core key hole slot.But every sheet pin is that isolation spaced apart becomes gapped, making key or stealing tool has advance and retreat to regulate gap and unblanks at key hole slot, especially present Che Shangyong lock, every sheet pin separates respectively arrangement and is seated on key tooth, unnecessary inclined-plane, one section, key tooth top, more convenient key or robber have the spacing of advance and retreat activity and operate and unblank, and also there is no positioner simultaneously.
Summary of the invention
Close finger setting theftproof lock of a kind of spiral, formed by lock body, lock core, sheet pin, spring, key etc., wherein: lock core keyhole forms the close film trap of screw type shape, and the bottom land of close film trap is concave edge, and described concave edge form sawtooth pattern shape by concave edge helical arrangement; Described lock core also has the close pin that is placed in close film trap, and described close pin edge be chimb, and described close sell and leans on close sell helical arrangement; Described lock body also has the chamber, interface of screw type, and the edge in chamber, described interface is sawtooth pattern shape, and chamber, described interface also has the close pin being located; Described lock core tail end also has locating slot, and described locating slot is also arranged by close film trap; Described locating slot also has the alignment pin being placed in, and described alignment pin also has plush copper, and described plush copper distribution is in keyhole; Described alignment pin also has re-entrant angle, and on described re-entrant angle towards keyhole; Described locating slot also has the spring leaf being placed in, and described spring leaf is by top alignment pin; Key top is salient angle, and described salient angle is to joining re-entrant angle; Described key is provided with the tooth that screw type is arranged, and described tooth is to joining close pin.
Advantage of the present invention:
1, lock core arranges the close film trap of sawtooth pattern shape, and the chimb of close pin is engaged in the concave edge of close film trap, makes mutually and the close pin leaning on located respectively the position of slip in close film trap.
2, sell and lean on close pin helical arrangement for close of lock core, make the tooth of key can not move forward and backward and regulate insurance tooth pitch the close pin of joining lock core phase and lean on.
3, in the locating slot of lock core, be provided with in the keyhole of alignment pin distribution in close pin, make key must inject keyhole top and strut alignment pin, and again limit positioning action, can not move forward and backward and regulate insurance tooth pitch.
4, there is the chamber, interface of screw type shape at shank, and chamber, interface be sawtooth pattern shape along limit, make mutually and the close pin leaning in place in the chamber, interface of sawtooth pattern shape and block lock core not move and cannot open lock respectively.
