The specific embodiment
Describe the present invention with reference to the accompanying drawings below, it is a kind of preferred embodiment in the numerous embodiments of the present invention.
Present embodiment provides a kind of two-bolt lock disc type three-dimensional coded lock, adopts driving disc spacing pressing rotary, can be to the safe door three-dimensional locking that other three sides can both locking except that hinge side, and the coded lock of rotating disc type coded lock and spoon dual independent protective of formula theftproof lock.
As shown in drawings, this two-bolt lock disc type three-dimensional mechanical code lock comprises a rotating disc type coded lock (1), a spoon formula theftproof lock (2), a multidirectional driving wheel (3), a driving gear (4), a tooth bar unlocking mechanism (5), three driven shaft mechanisms (6), five guide pin bushings (7), four latches (8), four return springs (9), a turning handle (10), supports the external door panel (11) of each assembly.Turning handle (10) connects multidirectional driving wheel (3) and driving gear (4), turning handle (10) is installed on the external door panel (11) of each assembly of supporting, coaxial fixing can the rotation in the same way of multidirectional driving wheel (3) and driving gear (4), the centre separates one with pad and keeps certain distance; When rotating with turning handle (10), multidirectional driving wheel (3) drives upper and lower side and left side driven shaft mechanism (6) motion, make the latch (8) that is threaded with driven shaft mechanism (6) flexible in vertical direction and horizontal direction, close open function thereby the national treasury door lock possesses three-dimensional; When rotating with turning handle (10), driving gear (4) drives tooth bar unlocking mechanism (5) move left and right in the horizontal direction, its parts coded lock dead bolt (5.2) and mechanical lock lock tube (5.3) are complementary with rotating disc type coded lock lock tongue slot (19) and spoon formula theftproof lock dead bolt (25) respectively, when rotating disc type coded lock (1) and a spoon formula theftproof lock (2) have a lock when not opening, the tooth bar unlocking mechanism then can not slide, and turning handle can't rotate.
Tooth bar unlocking mechanism (5) two ends sliding cylinders (5.4,5.5) pass guide pin bushing (7.4,7.5), and spacing and can be free movable at guide pin bushing by guide pin bushing, guide pin bushing (7.4,7.5) be fixed on the external door panel (11) of a supporting assembly.Tooth bar (5.1) on the tooth bar unlocking mechanism (5) is meshed with driving gear (4), coded lock dead bolt (5.2) on the tooth bar unlocking mechanism (5) is over against the central axis of rotating disk coded lock, when the lock tongue slot of each thumb wheel all forwarded the enable possition to, coded lock dead bolt (5.2) can pass lock tongue slot; When the lock tongue slot of one of them thumb wheel did not forward the enable possition to, coded lock dead bolt (5.2) is then blocked by thumb wheel can not pass lock tongue slot, and the tooth bar unlocking mechanism is by locking.Mechanical lock lock tube (5.3) on the tooth bar unlocking mechanism (5) be positioned at mechanical anti-theft lock dead bolt (25) directly over, when the rotary machine lock key, dead bolt (25) stretches out and just inserts in the mechanical lock lock tube (5.3), the tooth bar unlocking mechanism can't move left and right, by locking.
Shown in figure four, its coded lock dead bolt (5.2) of tooth bar unlocking mechanism (5) and mechanical lock lock tube (5.3) are an integral body, so rotating disc type coded lock (1) or spoon formula theftproof lock (2) all can locking tooth bar unlocking mechanisms (5), and separate, be independent of each other.Shown in figure five, be processed with three sliding-rail grooves (3.1) on the multidirectional driving wheel (3), sliding-rail groove (3.1) increases from sliding-rail groove (3.1) end to end gradually from the distance in multidirectional driving wheel (3) center of circle, at the stop place of sliding-rail groove the depression circular arc is arranged.Driven shaft mechanism (6) and multidirectional active (3) wheel link is a U type fork, has cylindrical hole on the fork, and the stud shaft that a diameter is housed is ￠ 10mm bearing passes the cylindrical hole on the fork, and is fixed by bolts in the sliding-rail groove (3.1) of multidirectional driving wheel (3).Driven shaft mechanism (6) is by spacing guide pin bushing (7) inboard, and spacing guide pin bushing is fixed on the external door panel (11) of each assembly of supporting.Shown in figure five, when multidirectional driving wheel (3) rotated, the bearing in the driven shaft mechanism rolled in sliding-rail groove, and the driven shaft of driven shaft mechanism moves back and forth in spacing guide pin bushing.So when multidirectional driving wheel (3) rotates, the motion down of upper end, lower end driven shaft mechanism in the vertical direction, national treasury door hinge offside driven shaft mechanism moves back and forth in the horizontal direction.Driven axle head axis direction has internal thread in driven shaft mechanism, matches with latch afterbody external screw thread.Lock pin extends the lock position under 90 ° of rotations of swing handle, bearing is positioned at the depression circular arc lowest part of multidirectional driving wheel sliding-rail groove.Interface place at driven shaft mechanism driven shaft and latch is equipped with spring, and the spring other end pushes up the external door panel sidepiece of a supporting assembly.Under the effect of spring force, contact is pushed mutually with the sliding-rail groove of multidirectional driving wheel by driven shaft mechanism, in multidirectional driving wheel and driven pulley mechanism kinematic process, is always the extruding contact condition, and it is smooth-going to move, and has eliminated the noise that causes because of drive gap.
This two-bolt lock disc type three-dimensional coded lock, at the national treasury outer side of door, turning handle (10), rotating disc type coded lock (1), spoon formula theftproof lock (2) can be equilateral triangle to be arranged or arranges arbitrarily by other requirements, can satisfy the operation requirement, can satisfy appearance looks elegant again.On thickness direction, because of rotating disc type coded lock (1), spoon formula theftproof lock (2), turning handle (10) dispersed placement, spatially there is not stack, so gross thickness is only big than its component thickness, can save a large amount of thickness space, thus the national treasury door can do thinner.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
