Description

Mechanical adjustable puzzle lock for door

The utility model relates to a kind of lockset.

The building door lock is eliminated basically and is used padlock at present, and adopt good looking appearance, good tongue type or the spherical pin tumbler lock of pick-proof security personnel's performance, but this class lock also exists the not good enough shortcoming of secrecy, and particularly key easily passes into silence or loses, and often makes troubles to the user.And coded lock that need not be key operated only is used for strongbox now mostly, and because of its structure is complicated, cost is higher.

The purpose of this utility model provides a kind of simple in structure, and is easy to use, and the password that safety is attractive in appearance is opened door lock, and password can conversion.

Design scheme of the present utility model is: carrying out technological improvement on the basis of common tongue type or ball-type pin tumbler lock, mainly is to substitute key operated lock core with the password unlocking assembly.This password unlocking assembly is made of wheel, password foreign steamer and capping assembly in interior bar, interior rod sleeve, the password, interior bar is a stock, run through lock box and interior rod sleeve, on establish the finger of bar moment of torsion in the transmission that matches with dial in the lock box, with with the vertical pin of on same axis, arranging of cipher wheel number equal amount, fixedly connected with handle in the one or both ends of interior bar; Interior rod sleeve freely is placed on the interior bar, fixedlying connected with the cipher wheel capping in two ends, offers the axial long slot bore that the displacement of lever pin nail is slided in holding on the sleeve body and follow closely radical horizontal slotted eye that equate and vertical perforation with axial long slot bore with one group with interior lever pin; Interior lever pin nail passes the sleeve slotted eye and stretches in the concave ring slot of wheel in the password that is set on the interior rod sleeve, the cylindrical central sleeve hole periphery of wheel also offers the gap slot that passes through vertically for interior lever pin nail in the password, sets position spring marble and pellet shot from a slingshot groove in the two adjacent passwords on the wheel tread mutually; The wheel periphery all is covered with the password foreign steamer in each password, establish the DIP spring marble mutually on its inner and outer circumferential surfaces of dependence between the password foreign steamer is taken turns with password is interior and be connected as resilient engagement, be carved with on the password foreign steamer outer circumferential side and the corresponding number number of each DIP spring marble with the pellet shot from a slingshot groove.

Below in conjunction with accompanying drawing the utility model is elaborated.

Embodiment 1. a ball-types sign indicating number alive cipher door lock, its lock box assembly (13), dead bolt (12) adopt the structure of common door lock with knob; The interior bar (3) of password unlocking assembly is the stock that runs through interior rod sleeve (22) and lock box, fixedly connected with screw (2) with handle (1) in two ends, bar is provided with the vertical pin (21) more than three, and the finger (23) that matches with dial hole in the lock box; Interior rod sleeve (22) is provided with an axial long slot bore (14), with more than three with long slot bore (14) vertical and is connected the perforation horizontal slotted eye (15), the two ends of sleeve are provided with external screw thread, are connected with front and back capping (4), (6), (9) and fixing with screw (5), (10); The centre bore (24) of wheel (20) is slightly larger than the external diameter of interior rod sleeve (22) in the password, and can be by the gap slot (25) of interior lever pin nail (21) along radially extending of hole, in wheel one side go up set groove circle (26) can hold stretch in the interior lever pin nail (21) of wheel, set a position marble spring (16), pellet shot from a slingshot (17) and pellet shot from a slingshot groove (27) mutually on the two adjacent interior wheel planes, do elasticity activity cooperation with this; Password foreign steamer (8) can be made the ladder lasso that mutual cover is joined, its outer ring appearance is carved with 0～9 number, offer on the secondary loops and the corresponding pellet shot from a slingshot of each number hole, DIP pellet shot from a slingshot (18), spring (19) are housed in the pellet shot from a slingshot hole, protruding being exposed in the secondary loops of the part of pellet shot from a slingshot (18) shown, match with groove set on wheel (20) all sides in the password, make to become the elasticity activity to connect in the password between the foreign steamer.

During use, rotational password foreign steamer (8), wheel (20) is along with synchronous rotation in the password, make number required on each password foreign steamer aim at (7) on schedule, and composition predetermined cipher number, take turns (20) this moment in each password gap slot (25) constitutes axial passage and overlapping with the axial elongated slot (14) on the interior rod sleeve (22), promoting handle (1) outdoors inwards, each horizontal slotted eye (15) in each pin (21) on the interior bar is promptly aimed on the rod sleeve, at this moment rotate handle (1), finger (23) set on the interior bar is promptly stirred lock box dial (28), makes in the dead bolt (12) and contracts, and door is opened.The inside and outside dual fail-safe of this lock, in indoor group of following lock-button (11), then outdoor commentaries on classics also can't be opened the door to password; After the outdoor locking, indoor can't opening the door.

This lock can also arbitrarily be changed password.Make code component be in opening by the original code operation earlier during replacing, even interior bar (3) can axially move freely, at this moment change special caliper (29) and be close to preceding capping (4) and be stuck on the interior bar (3) with having certain thickness fixed password, interior bar (3) can not be rotated, push inward handle (1) and touch clamp (29), correct on interior lever pin nail this moment (21) and be arranged in password wheel gap slot (25), any rotational password foreign steamer (8), wheel (20) is then motionless in the password, so just can reconfigure the password number.

Embodiment 2. a tongue types sign indicating number alive cipher door lock, its lock box assembly (13), dead bolt (12) adopts the structure of common tongue type pin tumbler lock, foreign steamer (20) in the password of password unlocking assembly, (8) structure is identical with embodiment 1, bar (3) is such with the structure of interior rod sleeve (22) with assembling in it: an end of interior bar (3) is fixedlyed connected with handle (1), the other end is positioned at sleeve (22), offer axial long slot bore (14) and one group of vertical horizontal slotted eye (15) that connects and match on the sleeve (22) with vertical pin group on the interior bar with long slot bore (14), the finger of unblanking (23) also is housed in the sleeve (22), this finger (23) has a cylinder (32), extend the flat group of tongue (35) that matches with dial hole in the lock box on one end face of cylinder (32), in addition interior interior bar (3) end of end and sleeve (22) contacts, offer on the cylinder (32) one with just dialling tongue (35), the corresponding helicla flute in side (33), then be provided with the chute pin (30) that matches with helicla flute (33) on sleeve (22) inwall, stage clip (31) is equipped with at the sleeve two ends, (34).

Using method: by the password cipher wheel that takes a turn for the better, the gap slot (25) of the interior wheel of each password (20) promptly is arranged in axial passage and sleeve (22) straight groove hole (14) is overlapping, the horizontal slotted eye (15) that pin group in rotation handle (1) makes on the bar is left on the sleeve enters wheel gap slot passage in axial slots and the password, at this moment interior bar (3) is pushed ahead under the effect of stage clip (31), promote finger (23) simultaneously, finger (23) is along helicla flute (33) half-twist when advancing, dial 90 ° of twist lock box dial rotations so dial tongue (35), contract in the dead bolt, door is opened.This lock can access to your password equally and change special caliper (29) and change password at any time.

The utility model structure is simpler, and is easy to use, avoided the trouble of daily band key, and password is the sign indicating number of living that can change arbitrarily, the secrecy height.
