(3) installation screw (52,63) arranged up and down, fixing with screw (8).The panel (107) that control spring bolt mechanism parts are installed is arranged in the middle of the front and back lock box covers (98,94), lock box cover (94,98) is screwed on jam plate (83), dead bolt is equipped with in perforate on the panel of jam plate (83), the top is arc dead bolt (80), the below is Square lock bolt (75), and arc dead bolt (80) and Square lock bolt (75) can pull out or be pressed into inside and outside the stretching of the Kong Lineng of jam plate (83).Arc dead bolt (80) front is connected with brace (79), brace (79) has return axle bar (108), axle bar (108) is equipped with return spring (91), two of return springs, another is contained in return prerotation vane (87), has return spare fixed guide seat (90) to connect interlock between axle bar (108) and the return prerotation vane (87).The termination of prerotation vane (87) joins with the termination up and down of interlock switch block (86), the front Ji Zui kiss of the rear end plush copper of switch block (86) and rocking arm (82) is stung; shake the head in the square hole clutch contact of return axle bar (108) in the end of rocking arm (82); the chain shell of two tongues (77) is fixed on the back lock box cover (98) with screw (93); the chain bolt of two tongues (76) is adorned at its center; left side, locking bolt (76) upper end contacts chain bolt (76) lower end roof pressure Square lock bolt (75) end face with the ladder position clutch of axle bar (108).Return spring and return supplementary plate (95) are equipped with in the back of Square lock bolt (75), and (95) bottom surface roof pressure interlock switch block (74), interlock switch block (74) switch block alignment pin (73) the card shelves that links are controlled it and swung.Switch block (74) can about half rotation moving, tie rod holes (97) is arranged in the middle of the switch block (74).Cipher mechanism: password wheel shaft (14) is outer to be sheathed with that active card has retainer spring sheet (101) on the outer gear wheel that cipher wheel interlock cover (43), cover (43) outside are cipher wheel (38), cipher wheel (38), be used for dialling location usefulness when changeing the cipher wheel numerical selection, another termination of spring leaf (101) is solid on support (27), and support (27) outside is cipher wheel shell (25).Handle (17) rotary head is with handle Connection Block (22), and square hole (53) is arranged in the Connection Block (22).Manufacture a square bar (4) between the front and back outer lock shell connection square hole.

When installing and using, reveal will dig the hole groove of the suitable jam plate of packing into (83) earlier.With the jam plate (83) of lock box (99) by hole (100) with the solid side of screw at door, the front and back outer lock shell is connected, square bar (4) passes square hole (15,53), handle (17, the 54) linkage of outer lock shell then, the cross connecting rod hole (97) of the internal lock box in key hole (1) of front and back outer lock shell is to the hole (61) of back outer lock shell (3).Debugging B breaking piece (62) can be under the not right situation of password can controlling party dead bolt (75) free in and out, be about to behind moving 90 ° of connecting rod (11) revolution front and back outer lock shell (2,3) closed and try again, three times is adjustable right repeatedly.Cipher wheel interlock cover (43) same gyration under the situation of stirring cipher wheel (38), when cipher wheel interlock cover (43) forwards projection outside the core over against the pit position of cipher wheel support (27) to, rotatable lock core (37) drives cam (30), but must be under dialling to the password situation, otherwise password wheel shaft (14) and head part (44) all can not on move, cam (30) just can not rotate, even can't rotate together with key, lock core to cam (30).When lock core, key are moved on to the angle of extreme position together with cam rotation on making the password wheel shaft, can dial the commentaries on classics cipher wheel, but this moment, cipher wheel interlock cover did not rotate, can change unlocking cipher at any time like this.This function is a password control key function.When Square lock bolt (75) control link (11) drove interlock switch block (74), interlock switch block (74) overcame the elastic force of auxiliary guide spring (9), and Square lock bolt return supplementary plate (95) is moved, and Square lock bolt (75) is laterally moved, and reached the switch lock action.When Square lock bolt (75) when shifting out, then making the chain bolt of two tongues (76) overcome return spring (78) elastic force such as (important are owing to there is Square lock bolt that ramp effect power is arranged) moves up, locking bolt (76) just can block the ladder position, bottom side of arc dead bolt return axle bar (180), make arc dead bolt (80) can't move into (handle can't plate moving), reach the multiple insurance purpose of increase with this, that is to say Square lock bolt (75) when stretching out, arc dead bolt (80) also can't retraction.When Square lock bolt (75) retraction, the chain bolt of two tongues (76) slips over Square lock bolt (75) under spring (78) effect inclined-plane contracts downwards, just can't block the ladder position of arc dead bolt return axle bar (108), so just can make arc dead bolt (80) freely come in and go out, promptly the moving handle of plate can enter, stretch out by the moving arc dead bolt (80) of plate.Interlock switch block (74) is to go control to rotate by Square lock bolt control link (11) at the twisting key, interlock switch block (86) connects the square bar twisting by the moving altogether front and back of handle and rotates, thereby drive rocking arm (82) swing overcomes the elastic force of spring (91) makes arc dead bolt brace (79) enter in the lock box together with arc dead bolt (80), reach the purpose of unblanking, when insurance handle (69) forwards on the vertical direction, insurance head part (55) has withstood the gap position of locked spacer (49), the handle Connection Block that rotates together with locked spacer (49) can't rotate like this, also promptly handle can't be pulled, and this function plays outdoors that the people can't unblank.When the insurance handle turns over 180 ° during at hoodle (68) position fixing knob (69) again, insurance head part (55) eccentric wheel (58) that handle (69) drives that is not insured withstands, promptly insuring head part (55) contracts downwards under the elastic force effect of return spring (56), head part (55) leaves the gap position of locked spacer (49), locked spacer (49) can be pulled with Connection Block that changes and handle, reaches insurance purpose like this.
