Description
A kind of building door that is used for particularly is used in the novel theftproof lock of dual-handle on office and the family housing door.
Existing theftproof lock is opening the door or at closing time, key will turn around at least, even two circles, generally locks not have handle, uses inconveniently, lacks the stronger sense of security simultaneously.
The purpose of this utility model is that a kind of novel structure, good looking appearance, safe and reliable will be provided, and uses the more convenient theftproof lock that has the dual-handle novelty.
Realize the technical solution of the utility model: the utility model mainly is made up of lock shell (1) and inner key cylinder (3), link right handles (4) and left handle (23) on lock shell (1) top by sector gear (2), rotating right handles (4) or left handle (23) can both make the big plug (24) in sector gear (2) the drive pilot hole (K) put in, stretch out, in the big plug (24) stage clip (25) is housed, pin (26) and play the pin (30) of guide and limit effect, big plug (24) stretches out the location will location-plate (5) location, location-plate (5), torsion spring (22) is linked by pin (6), be fixed in the gearcase (20) of inner key cylinder (3) bottom stage clip (19) is housed, gear (7), positioning key (8) and knob (9), be equipped with respectively in lock shell (1) both sides, bottom and be with left driving lever (17), the left lock core (16) of key (12 left side) and have right driving lever (13), the right lock core (14) of key (12 right side), stage clip (27) is housed in the small plug (10) in the pilot hole (F) and plays the pin (28) of guide and limit effect, shift fork (11) is located by pin (15), rotor plate (18) is by pin (29) location, rotor plate (18), location-plate (5) is linked by connecting rod (21).Rotate left driving lever (17) or right driving lever (13) on left lock core (16) or the right lock core (14) with key (12 left side) or key (12 right side), shift fork (11) is rotated in small plug (10) the indentation pilot hole (F), tooth bar (G) driven gear (7) on the small plug (10) rotates, and by location, the location on the gear (7) strong (8), rotor plate (18) drivening rod (21) makes location-plate (5) throw off big plug (24), because the effect of stage clip (25) is in big plug (24) the indentation pilot hole (K).This moment, lock was all opened.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1: be the utility model outside partial sectional view.
Fig. 2: be the utility model inner key cylinder (3) partial sectional view.
Fig. 1, Fig. 2, the people enters when unblanking, key (12 left side) drives left driving lever (17) the direction rotation in paper on the left lock core (16), behind left driving lever (17) contact rotor plate (18), continue rotation, and make rotor plate (18) when pin (29) rotates to the certain angle position, because the effect of connecting rod (21), location-plate (5) is rotated around pin (6), when the projection (B) on the location-plate (5) is all deviate from the groove (C) of big plug (24) bottom, because of pin (30) is fixed on the inner key cylinder (3), therefore, stage clip (25) promotes pin (26) all indentations towards pilot hole (K) the right on the big plug (24), and the elongated slot (X) on the big plug (24) plays guiding and position-limiting action.Because big plug (24) top has tooth bar (D), when plug (24) is towards the indentation of pilot hole (K) the right greatly, drives sector gear (2) and rotate counterclockwise, at this moment, left handle (23) and right handles (4) are rotated an angle simultaneously.Key (12 left side) will continue rotation, and the left driving lever (17) on the left lock core (16) is pressing the lower platen (H) on the rotor plate (18) to rotate an angle again around pin (29).Fig. 2, top board (R) on the rotor plate (18) will press the pressing plate (S) on the shift fork (11) to clockwise rotate an angle around pin (15), make small plug (10) towards all indentations of pilot hole (F) the right, pin (28) is fixed on the inner key cylinder (3), and the elongated slot (E) on the small plug (10) plays guiding and position-limiting action.Because the top of small plug (10) has tooth bar (G), in the time of small plug (10) indentation pilot hole (F) the right, gear (7) in the driven gear box (20) rotates counterclockwise, because the effect of stage clip (19), when gear (7) when turning an angle, the positioning key (8) on the gear (7) just inserts in the locating hole (Y) on the gearcase (20).Small plug this moment (10) just can not freely stretch in pilot hole (F), and at this moment, lock is all opened, and key (12 left side) reposition is taken out, and pushes and enters house.
The people locks a door after entering house, hold right handles (4) when door is closed, Fig. 2, make right handles (4) when clockwise rotating, sector gear (2) drives big plug (24) when pilot hole (K) left side reaches to a certain degree, when just right handles (4) is basic vertical with ground, because the effect of torsion spring (22), location-plate (5) is upwards lifted, projection (B) on the location-plate (5) just inserts in the groove (C) of big plug (24) bottom, at this moment, big plug (24) just locks and can not freely stretch again.
If small plug (10) also will be locked, Fig. 1, press a lower knob (9) with finger, the locating hole (Y) on the gearcase (20) is just deviate from location on the gear (7) strong (8), because the effect of the interior stage clip of small plug (10) (27), small plug (10) is stretched out towards pilot hole (F) left side, and this moment, door all locked.
Only need lock small plug (10) in the house if the people advances, door is closed, press a lower knob (9) with finger, small plug (10) just stretches out to be locked.When the people goes out the house, Fig. 1, directly turning knob (9) small plug (10) is with regard in the indentation pilot hole (F), and door just can be opened.
People's action of going out to open the door is advanced the house inward with the people and is moved the same, before the people goes out the house, need press a lower knob (9) earlier, make small plug (10) stretch out pilot hole (F), because small plug (10) head (M) is the inclined-plane of about 45 degree, the people can directly hold left handle (23) without door is closed, at this moment, small plug (10) but on the automatic locking, rotate left handle (23) simultaneously, big plug (24) is stretched out to be locked, the action of locking a door in the follow-up house is the same, and at this moment, door just all locks safely and reliably.
The utility model novel structure, good looking appearance, generous is no more than half-turn with key and key turns angle in the time of only need opening the door, and is easy to use, sturdy and durable, safe and reliable, is specially adapted to various security doors made of iron.
