Abstract
The utility model discloses a burglar-proof puzzle lock, which is that an outermost puzzle disc (5) in a puzzle rotary disc assembly of the existing puzzle lock is made into a puzzle disc the diameter of which is larger than the diameters of other puzzle discs (6) or the contact surface of the puzzle disc of the puzzle rotary disc assembly and a lock tongue piece of a lock tongue assembly of the existing puzzle lock is made into an inclined surface which has a short inner part and a large outer part. The common purpose is that when the lock tongue piece of a lock tongue assembly is contacted with the outermost puzzle disc (5), the lock tongue piece is not contacted with the other puzzle discs (6). When a thief opens the lock, because the lock tongue piece is first inserted into a gap of the outermost puzzle disc, the puzzle disc is not rotated, the puzzle disc can not drive the rotation of the other puzzle discs, which makes the thief not hear the sounds of gap contact of the lock tongue piece and the other puzzle discs in order not to open the lock. Therefore, the utility model has the advantage of high burglar-proof performance.
Description
The utility model relates to a kind of coded lock, particularly puzzle theft-proof lock.
Existing coded lock comprises password rotating disk assembly, dead bolt assembly and lock body assembly, its open method is with key lock to be opened earlier, rotational password rotating disk assembly then, make the breach correspondence on each combination disk on the password rotating disk assembly, again by the handle drives dead bolt assembly on the dead bolt assembly, strike plate is retracted in the breach of all combination disk, door can be opened.The shortcoming that this coded lock exists is: when strike plate retreats, all simultaneously and each combination disk EDGE CONTACT.Because this defective, the robber can pull the dead bolt assembly with hand when the such coded lock of pirate of the open, make strike plate tightly touch the edge of each combination disk, the runner of rotational password rotating disk assembly then, and when carefully listening each combination disk to rotate, the abnormal sound when its breach contacts with strike plate, to judge the position of each combination disk breach, remember its corresponding password, can will lock pirate of the open, so, present this coded lock exists easy pirate of the open, the shortcoming that security performance is not high.
The purpose of this utility model provides a kind of strike plate that makes and contacts at first with outermost combination disk edge, extremely difficult pirate of the open, and the puzzle theft-proof lock that security performance is high is to solve the deficiencies in the prior art part.
In order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is: the diameter of the outermost a slice combination disk in the existing password lock cipher rotating disk assembly is greater than the diameter of other combination disk, when the strike plate of dead bolt assembly contacted with outermost a slice combination disk, strike plate did not contact with other combination disk.
Goal of the invention of the present utility model can also be to realize like this: the strike plate of existing coded lock dead bolt assembly is contacted the hypotenuse that one side is made interior short foreign minister with the combination disk of password rotating disk assembly, when the strike plate of dead bolt assembly contacted with outermost a slice combination disk, strike plate did not contact with other combination disk.
Because the structure design that the utility model adopted makes the strike plate of dead bolt assembly contact at first with outermost a slice combination disk, and does not contact with other combination disk.When rotational password rotating disk assembly, pull the dead bolt assembly simultaneously, like this, the strike plate of dead bolt assembly will be inserted in the breach of outermost a slice combination disk at first, outermost a slice combination disk can't be rotated further again, because other sheet combination disk all are to lean on the rotation of its outer a slice combination disk to drive its rotation, because of the effect of strike plate, outermost a slice combination disk can't be rotated, so other combination disk also can't be rotated.The robber because it can't hear the sound that strike plate contacts with other combination disk breach, also just can't judge other residing position of combination disk breach and corresponding passwords when this puzzle theft-proof lock of pirate of the open like this, thereby can't this lock of pirate of the open.Therefore the utility model compared with prior art has the high advantage of theftproof performance.
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
Further describe the utility model below in conjunction with accompanying drawing.
Embodiment 1: puzzle theft-proof lock as shown in Figure 1, comprise the password rotating disk assembly of existing password lock and the strike plate 1 of dead bolt assembly, password rotating disk assembly is by the rotating disk 3 of band rotating shaft 2, fixed cover 4 and 3-5 sheet combination disk constitute, be carved with scale on the rotating disk 3, rotating shaft 2 is inserted in the fixed cover 4, the end of rotating shaft 2 is fixed with outermost a slice combination disk 5, other each sheet combination disk 6 are installed on the fixed cover 4, and can on fixed cover 4, rotate, be equipped with breach 7 on combination disk 5 and other each sheet combination disk 6 and drive the driving lock shaft 8 that next combination disk is rotated, the diameter of combination disk 5 is greater than the diameter of other each sheet combination disk 6, when the strike plate 1 of dead bolt assembly contacted with last a slice combination disk 5, strike plate 1 did not contact with other combination disk 6.The diameter of other each sheet combination disk 6 can be the same, also can be different.
Embodiment 2: strike plate 1 contacts one side and is interior short foreign minister's hypotenuse with the combination disk 5,6 of password rotating disk assembly, and the diameter of combination disk 5 can be bigger than the diameter of other each sheet combination disk 6, also can be identical with the diameter of other each sheet combination disk 6.All the other are with embodiment 1.
Claims (5)
1, puzzle theft-proof lock, comprise the password rotating disk assembly of existing password lock and the strike plate (1) of dead bolt assembly, password rotating disk assembly is by the rotating disk (3) of band rotating shaft (2), fixed cover (4) and 3-5 sheet combination disk constitute, rotating disk is carved with scale on (3), rotating shaft (2) is inserted in the fixed cover (4), the end of rotating shaft (2) is fixed with outermost a slice combination disk (5), other each sheet combination disk (6) are installed in fixed cover (4) and go up also and can go up rotation at fixed cover (4), be equipped with breach (7) on combination disk (5) and other each sheet combination disk (6) and drive the driving bearing pin (8) that next combination disk is rotated, the strike plate (1) that it is characterized in that the dead bolt assembly inserts in the breach (7) of outermost a slice combination disk (5) behind the segment distance, just contacts with other combination disk (6).
