Referring to Fig. 2 and Fig. 3, solution of the present utility model also includes following content.Be stamped lock cap (26) in the front side of lock housing body (1), the front portion of lock cap (26) has one by last, following two dog screws (27,28) with its upward location cover plate (29) that is connected mutually, between last location cover plate (29) and lock cap (26), slide and be inserted with a upper lock tongue slurcam (30) that protrudes upward, upper lock tongue slurcam (30) has the vertical chute (31) that slides on the dog screw (27), the left side that has that is stacked in outside the lock cap (26), right two pusher arms (32,33) main slurcam (34), its underpart offers slurcam chute (35), have the main linkage pin displacement chute (36) of level on the lock cap (26), the main linkage pin (5) of aforementioned junction panel (4) is sliding to be inserted in main linkage pin displacement chute (36) and the slurcam chute (35), upper lock tongue slurcam (30) bottom has the groove that is meshed with left pusher arm (32), the top has the upper lock tongue connector (37) that can link to each other with external upper lock tongue, the top cunning of main slurcam (34) is inserted between location cover plate (29) and the lock cap (26), and the perforate on its top slides over down on the dog screw (28); Lock cap (26) bottom has a following location cover plate (39) that is connected mutually by dog screw (38) and its, the following dead bolt push pedal (40) of imbrication on lock cap (26) and main slurcam (34), its underpart cunning is inserted in down between location cover plate (39) and the lock cap (26), and have the chute (41) that slides on the dog screw (38), the top of following dead bolt slurcam (40) has the groove that is meshed with right pusher arm (33), and the bottom has the following dead bolt connector (42) that can link to each other with external dead bolt down.
Referring to Fig. 1 and Fig. 3.Lock core (18) adopts lock cylinder, also can adopt the shell fragment lock core, because of being prior art, so structure chart omits.Upper lock tongue connector (37) and following dead bolt connector (42) are Screw hole structure in an embodiment, so as respectively with external upper lock tongue and following dead bolt mutually screw thread spin, also can adopt other connected mode.Main dead bolt (3), oblique dead bolt (20) and rotary handle (23) are all made the structure that segmentation links to each other in an embodiment.
The utility model with said structure is loaded on lock on the door when concrete the use on request, upper lock tongue connector (37) and following dead bolt connector (42) is connected the upper lock tongue and the following dead bolt (its length is decided according to the concrete size of door) of strip respectively.After lock installs, two lock cores (18) and two rotary handles (23), the inside and outside both sides of separation door, the indoor and outdoor all can be operated.If main dead bolt (3) all contracted before this in lock housing body (1), promptly be in the state do not locked.Be inserted in lock core (18) and left-handed rotation with key (17) this moment, drive is stirred tongue (19) and is stirred main dead bolt buckling plate (9), overcome the pressure of button bit spring (13), make on the main dead bolt buckling plate (9) and move, button bit pin (12) leaves button bit groove (6), stir tongue (19) and enter DIP groove (7) on the main dead bolt (3) simultaneously, and when lock core (18) continues to anticlockwise, main dead bolt (3) is stirred one left, button bit pin (12) on buckling plate this moment (9) begins to enter second button bit groove (6) from first button bit groove (6) of main dead bolt (3), meanwhile, stir tongue (19) and leave DIP groove (7), buckling plate (9) is no longer stirred the pressure of tongue (19), so under the pressure of button bit spring (13), button bit pin (12) is pushed second button bit groove (6) of main dead bolt (3) fully, and main dead bolt (3) is locked, by lock state a little less than the lock state does not enter, the about 10mm of the degree of depth that main dead bolt (3) stretches out.
If continue (18) 180 ° of rotary locking cylinders with key (17), then repeat said process again, stir tongue (19) main dead bolt (3) is stirred one more left, button bit pin (12) pushes the 3rd button bit groove (6) from second button bit groove (6) of main dead bolt (3), main dead bolt (3) is locked, enter strong lock-bit state by weak lock-bit state, the weak lock-bit of the depth ratio that main dead bolt (3) stretches out goes out 10mm deeply.With key (17) rotary locking cylinder (18) to the right, just main dead bolt (3) can be returned to weak lock-bit and lock-bit not successively from strong lock-bit, its operating principle is identical with the situation that above-mentioned main dead bolt enters lock-bit.
Referring to figure one.Tiltedly dead bolt (20) is mainly used in the someone when being in, in the into manually opened usefulness of going out.The handle (23) that turns clockwise drives oblique dead bolt and opens plate (21) and rotate, and the head of drawing together of its protrusion drives an oblique dead bolt (20) and moves right, and withdraws from the doorframe lockhole, is in not lock-bit as main dead bolt this moment (3), and then door can freely be opened.When handle (23) when unclamping, because the effect of handle return spring (22) will open plate (21) forced back and reset, oblique dead bolt (20) also resets owing to the effect of back-moving spring (24) is pushed back the original place.And tiltedly dead bolt (20) can freely go out into activity when turning handle (23) not, thus utilizing the slip of its hypotenuse at closing time, can be automatically with oblique dead bolt (20) indentation, lock and automatically reset when entering frame hole.At main dead bolt (3) when being in strong lock-bit, stop that projection is locked with oblique dead bolt (20) on the junction panel (4), play the effect of the intensity of strengthening lock.
Referring to Fig. 2 and Fig. 3.When main dead bolt (3) when being in strong lock-bit, the main linkage pin (5) that connects together with it is in the Far Left of chute (36) that are shifted among Fig. 2, drive main slurcam (34) and clockwise rotate an angle, so a left side promotes swing arm (32) and right pusher arm (33) promotes upper lock tongue slurcam (30) and following dead bolt slurcam (40) respectively, they are moved respectively up and down, thereby promote the upper lock tongue and the following dead bolt that link to each other respectively with them, inject respectively doorframe on, following lockhole, this moment, slurcam (30) and slurcam (40) were in the position of highest and lowest respectively, promptly were to lock state by force.
When main dead bolt (3) is in weak lock-bit, main linkage pin (5) moves to the interposition of chute (36), make left pusher arm (32) and right pusher arm (33) be in left and right sides parallel position among Fig. 2, upper lock tongue and following dead bolt are pulled out a part from the last lockhole and the following lockhole of doorframe respectively, be in weak lock state.
When main dead bolt (3) when weak lock-bit retreats to not lock-bit, main linkage pin (5) moves to the rightmost of chute (36), drive main slurcam (34) and rotate counterclockwise an angle, so left pusher arm (32) and right pusher arm (33) promote upper lock tongue and following dead bolt respectively, make them respectively downwards and move up, all withdraw from the upper and lower lockhole of doorframe, be in not lock-bit state.
The utlity model has four dead bolts, and when being in strong lock position, tiltedly dead bolt also can be in locking state, the degree of depth that the master lock tongue is locked into is also dark than general lock, and this has just strengthened the security insurance reliability of this lock, effectively anti-prizing anti-toggle greatly. This lock is handsome in appearance, easy for installation, is applicable to that all kinds of building timbers and steel casement door use. Compare with theftproof lock of the same type, it is simple in structure, and cost is cheap, easily accepts for users.
