In view of this, to the problems referred to above, propose a kind of reasonable in design and effectively improve the mutual padlock of tetrad group two-man act biplate of above-mentioned disappearance.
The utility model content
The purpose of the utility model is to provide tetrad group two-man act biplate mutual padlock, and the anti-pirate of the open performance that overcomes original lock is low, and lock core is connected insecure with lock body, and key and lock core cooperate uncompacted shortcoming.
In order to reach above-mentioned purpose, the utility model provides tetrad group two-man act biplate mutual padlock, comprise dead bolt that the inner lock core of lock body, lock body, lock core connect, with the axial corresponding key of keyhole; Said lock core is provided with four groups of locking plate grooves and spring groove, and every group of locking plate groove and spring groove are equipped with a pair of mutual padlock sheet and corresponding a pair of spring.
Said lock body front portion is provided with the location end face groove, and lock core end face platform is provided with locating piece, and said lock core afterbody is provided with dead bolt Ka Tai, and said lock core is axially arranged with keyhole; Bayonet socket is set on the dead bolt, and the bayonet socket upside is that dead bolt prolongs piece, and said dead bolt places on the dead bolt Ka Tai of lock core afterbody through bayonet socket.
Said lock body outside is provided with positioning table, and the lock body end face is provided with locating slot, and the lock body body is provided with one group of corresponding locking plate breach, and said locating piece places locating slot.
Also be with back-up ring on the said lock core, offer draw-in groove on this back-up ring circle wall, jump ring is housed in the draw-in groove.
Said key is two-sided flute profile, and the flank of tooth is provided with the table top with the lock core location.
Compared to prior art, the utility model can more effective anti-pirate of the open, has better solved the firmness of lock core, lock core, lock body and key cooperate closer.Tetrad group two-man act biplate button mutually is to adopt four groups whenever to be assembled with bipack-film and pair of interacting spring; Two-fold locking plate is under the interaction of spring; The key tooth that can link closely, key again can power transmission when stirring in spring and locking plate, make it stir flexibly and shrink.The bilateral tooth of key and bipack-film are under the cooperation of spring, and after locking plate folded, lock core just can rotate according to the orientation angle position.At this moment lock is opened, and locking plate opens when the breach of lock body, and two-sided eight locking plates block lock body simultaneously, and this moment, lock just pinned, and the mutual button of eight locking plates has just increased the anti-pirate of the open and the fastness of locking with opening mutually.The lock body upper surface groove directly locating piece cell body on lock core combines, and has increased the fastness of lock body and lock core, and the back-up ring internal diameter cooperates with whole lock core end face external diameter, and is all firm the connecting together of the whole series lock, firmer again.
