The technical solution of the utility model is:: a kind of rolling-gate safety lock, comprise lock casket, lock core, dead bolt, driving gear, driven gear, lock core is connected with driving gear and passes and lock the casket base plate, the driven gear that turning cylinder is installed on the lock casket base plate meshes below driving gear and with driving gear, is provided with hinge on the left and right limit of driven gear and is connected with the horizontal dead bolt movable connecting rod that passes lock two sides, the left and right limit of casket groove.

The driven gear lower end is connected with the grip block of vertical dead bolt by hinge, connecting rod, upper and lower grip block is approximate rectangular, the centre is equipped with the vertical dead bolt of left and right symmetry, two dead bolt rotating shafts are fixed between upper and lower grip block, on the grip block of the upper and lower end between adjacent two dead bolts, respectively be fixed with spacing bearing pin, two dead bolt edges between two spacing bearing pins are equipped with back-moving spring, there is an add-in card that is connected as a single entity with it and has vertical chute in the upper right corner at following grip block, is set with a bearing pin that is fixed on the lock casket base plate in the groove.

The lock tube of lock core keyhole one end passes lock casket upper cover plate and is fixed on the limiting plate, limiting plate is fixed on the lock casket negative, the limiting plate left and right sides has the cross spacing groove, suit is fixed on the spacing bearing pin on the horizontal dead bolt connecting rod in the groove, lock core is connected with driving gear with shift fork by jump ring, and the increment in shift fork outer end and driving gear vertical moving tooth that makes progress cooperates.

On the lower side panel of the lock casket lower right corner, be equipped with by fairlead, push rod, the automatic mechanism for locking up that clamp and spring are formed, top stem casing is contained in the fairlead, there is boss the push rod upper end, clamp is fixed on the lock casket negative by rotating shaft, clamp upper end and left side respectively have one inwards with the outside plate that stretches out, there is a spring housing to be contained in the rotating shaft of clamp, both ends of the spring is clamped on the protruding plate of lock casket one side and clamp, when unblanking, the disjunctor add-in card lower end of grip block has a groove to cooperate end in contact on the protruding plate of clamp and the push rod with the clamp plate that stretches out inwards under the vertical dead bolt.

Laterally the movable connecting rod of dead bolt is two hinge bars, and horizontal dead bolt inserts in the doorframe of both sides or in the body of wall by hole or groove when locking, vertical dead bolt and surface-based snap fit.

Horizontal dead bolt first piece connecting rod hinged with driven gear can be the curved hinge bar.

Lock back side jug is connected with driving gear or driven gear.

The utility model beneficial effect: the left and right two horizontal dead bolts of (1) intrinsic safety full lock are connected with follower by hinge, and are simple in structure, adopt limiting plate mechanism, stuck phenomenon can not occur, easy for operation, flexibly.(2) safety is locked in vertical direction increases vertical dead bolt, and vertical dead bolt structure is ingenious, firm, strengthened the anti-theft security performance.(3) the safety lock construction is fairly simple, and cost is lower, promotion and implementation easily.
