Abstract

The utility model relates to a keyboard numerical lock, which belongs to the improvement of the numerical lock. With the adoption of the key form appearance and modeling, the utility model not only does not need to be opened or closed by keys, but also can be conveniently opened and closed in the condition of any dull light (or in darkness). When opening or closing the lock, press the key to make the internal movable pin box do oriented movement, and pull the quick rod to rotate so as to ensure the opening and closing of the lock. The oriented movement of the movable pin box is determined by the key sequence arranged according to the mathematical logic of permutation and combination.

Description

Keyboard numerical lock

The utility model relates to a kind of lockset of novelty.

The present lockset used always of people, although form is varied, nothing more than 2 points: the one, with key operated lockset, people have the trouble of carrying key; The 2nd, with the lockset that logarithmic code is opened, this makes people at dim light or open the lockset trouble night.

Task of the present utility model provides a kind of lockset, neither need be with key operated, and the lockset that under any dim light condition, all can open easily.

Task of the present utility model is finished like this: as shown in Figure 1, watch from the outer of lockset, have only several buttons (being illustrated as six) and knob.Behind the button order button of predesignating of unblanking, the twisting knob can open the door.Close behind the door, according to predesignate shut button order button after, be about to the door lock jail.Its this duty is formed by following structure.As shown in Figure 2, Xiao's box of living is being arranged different Xiao alive 3 of several bevel directions for 2 li regularly, is with compression spring 5 on the button 4, and an end on Xiao inclined-plane of living is aimed at by the thin portion of the head end of button.When by certain button, the head end of button moves along Xiao inclined-plane of living, and Xiao Ze drive alive Xiao's box alive (or to the right) left moves.Xiao's bevel direction can be determined arbitrarily owing to live, and during by each button, the moving direction of Xiao's box of living is also just different.The suitable selection of Xiao's bevel direction alive, the efficient Xiao's box of the reflection arrangement of (or to the right) movement law left on button.The effect of compression spring is after making button lose external force, can automatic homing.As shown in Figure 3, the fulcrum that is the quick bar 6 of lever form is fixed on the lockset framework 1, and quick bar right-hand member head probes in the recess of lock pin 7, and the limit that the left end triangular facet is convex concave contacts with Xiao's box of living, and small extension spring 8 plays the positioning action of quick bar.When button moves Xiao's box alive, promote the protruding place on quick bar convex concave limit, quick bar is rotated, when Xiao's box of living is not mobile, the recess on then quick bar convex concave limit withstands on Xiao's box alive, exerts pressure by the small extension spring that is connected with quick bar, makes Xiao's box alive can not automatic rollback.Shown in Fig. 3,4, shift fork 9 is fixed on the tappet 10 that traverses lock pin, and knob 11 is fixed on an end of tappet, and the pillar 12 that is fixed on the lock pin by fork controls.Suit compression spring 14 on the through post 13, the one end inserts the left part of lock pin.Press button regularly, Xiao's box alive is moved to left, quick bar clockwise rotates, and after its right-hand member head withdrawed from the lock pin recess, the twisting knob drove pillar by shift fork, and lock pin is moved to the left, and withdraws from the lock box 15 of its head from doorframe, can open the door.When lock pin lost external force, the compression of through post was spring energized, and the lock pin head is probeed in the lock box, at this moment, pressed button regularly, and Xiao's box alive is moved to right, and quick bar then rotates counterclockwise, and the right-hand member head probes in the recess of lock pin, was about to the door lock jail.

Claims
