The utility model also comprises a rotating wheel which coaxially arranged above the driven gears, and the driven gears are provided with a sector annular groove; the rotating wheel is connected with the main bolt through a connecting rod, and the rotating wheel is provided with a groove utilized to store the positioner roller; the upper driven gear is provided with a curve capable of pushing the positioner roller to leave the groove. The utility model has the advantages of small size, low cost and best design effect of driven gears.
Description
Technical field
The utility model belongs to field of lockset, particularly relates to a kind of lock that is exclusively used in security door.
Background technology
Safe-guard door lock is very high to the requirement of safety, and driving dead bolt with gear drive is a kind of ideal method.A kind of gear-driven safe-guard door lock is arranged on the overseas market, it has up and down two coaxial driven gears, also has gear on the tapered end, can and drive its rotation with driven gear engagement up and down, last driven gear wherein links to each other with main dead bolt by connecting rod, and following driven gear is controlled the motion of oblique tongue; Be provided with positioning roller in the lock and limit the track of its movement locus, have two grooves that match with positioning roller up and down on the driven gear, on the last driven gear and have a curve that positioning roller can be pushed away groove; When turning tapered end, driven gear rotates, and at first positioning roller is pushed away groove, and driven gear is rotated further, and last driven gear can spur main dead bolt, and driven gear was rotated further under main dead bolt put in place afterwards, can spur oblique tongue.This lock is controlled driven gear with tapered end, the pulling dead bolt, and transmission process is more direct.But there are two shortcomings in it, the one, the groove of ccontaining positioning roller all is located on the driven gear with the curve that pushes away positioning roller, as curve smoothing then positioning roller easily from groove, deviate from, positioning action is weakened, be difficult to more again positioning roller is pushed away from groove as curve, be difficult to the equalization point that finds to make the best of both worlds; The 2nd, under this structure, require driven gear and tapered end that certain gear ratio is arranged, and tapered end is because process relation, can not do very for a short time, the number of teeth of such two driven gears certainly will be more, and diameter is bigger, thereby cause the size of whole lock bigger, and cause that cost raises.
Summary of the invention
The technical problems to be solved in the utility model is that the size of safe-guard door lock is bigger, and a kind of small size, gear-driven safe-guard door lock cheaply are provided.
For this reason, the utility model has adopted following technical scheme: safe-guard door lock, comprise housing, tapered end, handle, main dead bolt, last driven gear, following driven gear and positioning roller, two driven gears are coaxial up and down, have driving gear on the tapered end, can and drive its rotation with the engagement of driven gear up and down, it also comprises a runner, places driven gear top and coaxial with driven gear, has the groove of fan annular on the driven gear; Runner links to each other with main dead bolt by connecting rod, and on the runner and be provided with the groove of ccontaining positioning roller, last driven gear is provided with the curve that positioning roller can be pushed away groove.
The utility model also can adopt further technical scheme: have the side connecting rod on the runner, link to each other with the secondary dead bolt that stretches out housing; Establish the shift fork of the oblique tongue motion of oblique tongue and control in the housing, have the projection that cooperates with this shift fork on the following driven gear, also have the pin that matches with this shift fork on the handle; The coaxial block that is pivoted with of handle can limit the motion of main dead bolt.
Be the sports limiting to positioning roller, the utility model can adopt two kinds of schemes: the backstay that is pivoted on the handle, and positioning roller places on the backstay; Or the track that limits the positioning roller movement locus is set on housing.
The utility model is controlled main dead bolt and secondary dead bolt with runner, above driven gear pushes away positioning roller, after function is separated, free transfer part branch is arranged on the driven gear, driven gear needn't be consistent with the desired gearratio of lockset with the gear ratio of tapered end, can reduce the number of teeth on the driven gear like this, and the diameter of driven gear and runner does not all need very big, the size of whole lock can be dwindled, and cost has also reduced; The groove of ccontaining positioning roller is located on the runner, and the curve that pushes away positioning roller is located on the driven gear, can not interact, and can design best effect.

Structural representation when Fig. 2 is the utility model blocking.
Fig. 3 is the part drawing of runner in the utility model.
Fig. 4 is a part drawing of going up driven gear in the utility model.
Fig. 5 is the part drawing of following driven gear in the utility model.
Preferred forms
Referring to Fig. 3.Runner 30 is provided with the groove 32,33 of two ccontaining rollers.
Referring to Fig. 4.Last driven gear 40 has the pin-and-hole 41 that can wear pin, can push away the curve 42,43 of roller, and the groove 44 of fan annular is provided with tooth 45 in its part outer rim.
Referring to Fig. 5.Following driven gear 50 has the projection 52 that cooperates with shift fork, and the groove 54 of fan annular is provided with tooth 55 in its part outer rim, and its number of teeth is more than the tooth on the last driven gear 45.
Referring to Fig. 1, Fig. 2.Safe-guard door lock comprises housing 1, tapered end 2, and handle 3, main dead bolt 4, tiltedly tongue 5 has runner 30, last driven gear 40, following driven gear 50, arranged in co-axial alignment from top to bottom in the housing; Have driving gear on the tapered end 2, can and drive its rotation with the engagement of driven gear up and down; Be pivoted with the backstay 6 of band positioning roller 7 on the handle, positioning roller 7 can match with the groove 32,33 on the runner, is placed in wherein.Runner 30 links to each other with main dead bolt 4 by connecting rod 9 by being arranged in the pin in the groove 44,54 again; Runner links to each other with secondary dead bolt 11 by side connecting rod 10 simultaneously.Also be provided with shift fork 13 in the housing, shift fork can be controlled the motion of oblique tongue, and the projection 52 on the following driven gear 50 matches with shift fork; Also have the pin 14 that matches with shift fork on the handle 3, the also coaxial block 15 that is pivoted of handle.
The utility model is when unblanking, turn tapered end 2 with key, gear promptly drives up and down, and driven gear 40,50 rotates, curve 42 on the last driven gear at first pushes away positioning roller 7 groove 32 of runner 30, runner 30 begins to rotate then, in the main dead bolt 4 withdrawal housings 1 of connecting rod 9 pullings, this moment, positioning roller 7 entered another groove 33 on the runner 30, made main dead bolt be fixed in opening; Continue to turn tapered end 2, because of the last driven gear number of teeth is less than driven gear down, driven gear 40 no longer rotates on this moment, tapered end 2 only meshes with following driven gear 50, and driven gear 50 is rotated further under driving, and its projection 52 catches on shift fork 13, stir in the oblique tongue 5 withdrawal housings 1, tiltedly tongue is opened; Also can turn handle 3, rotate shift fork, open oblique tongue 5 with pin 14.
The utility model is when locking, oppositely turn tapered end 2 with key, gear driven driven gear 40,50 up and down rotates, curve 43 on the last driven gear pushes away positioning roller 7 groove 33 of runner, runner 30 rotates then, by connecting rod 9 main dead bolt 4 is released housing, this moment, positioning roller 7 entered the groove 32 on the runner, and main dead bolt is fixed in blocking.Turn handle 3, block 15 can be gone to main dead bolt 4 times, main dead bolt can not be moved, play the effect of insurance.
