Abstract
A cipher lock has a rotary part extending outward to form a rotary axle with external spiral thread. The slotted rotary disk, fastening part and nut are installed to said rotary axle. It is an improvement on existing cipher lock for higher safety and reliability without additional cost.
Description
The present invention relates to a kind of coded lock.
Coded lock of the prior art, its rotary part have protruding of being convenient to catch, and the rotary disk that rotary part extends in the rotating shaft has only a groove, and rotary disk just fixes by the anterior bearing pin of rotating shaft is set.As can be seen, the coded lock of this kind structure is very dangerous.At first,, be easy to catch protruding,, can make that lock core mechanism is whole to pull out, do not have the due effect of lock as long as outwards pull at slightly with general apparatus commonly used; Secondly, has only a groove on the rotary disk, in rotating the rotary part process, once run into the moment of predetermined lockset position of coupler, faint sound can take place when being single groove on the rotary disk and locking bolt contraposition, and disk of this sound contraposition can only send a sound, concerning the veteran, promptly can lean on this sound that coded lock is opened.In addition, because existing password is locked in and is provided with the spring that is used to locate between rotary disk and the rotary part, this spring is subjected to high temperature easily to lose elasticity, makes the rotary disk dislocation, loses its due effect.
Task of the present invention provides a kind of safe and reliable coded lock, and solution sends the certainty sound in the check mark process and lock core is drawn out problem, can overcome above-mentioned weak point effectively.
The present invention includes a rotary part, this rotary part axially extends outward one and has externally threaded rotating shaft, the tumbler disc of peripheral trough of belt is installed on the axle, particularly only has a tumbler disc than deep trouth, each tumbler disc can be independent of other and by the rotary part adjustment; With one show and have the fastener that is used for fixing rotary part of character, its below is provided with a securing member, and this securing member also is provided with the internal thread that the external screw thread with above-mentioned rotating shaft is complementary; And nut that is arranged on above-mentioned rotating shaft front end.
Described tumbler disc can be provided with three, and each tumbler disc periphery is provided with rectangular channel or semi-circular groove equably, has only a darker groove in these grooves.
Described rotary part can be arranged to the geometrical body of cylinder or cone or other type.
Be provided with flexure strip between described securing member and its nearest tumbler disc.
Because the present invention adopts and is inconvenient to catch rotary part and securing member, and adopts helicitic texture between securing member and the rotating shaft, so lock core can not be pulled out by force, can improve the safety of lock; Rotary disk is provided with a plurality of grooves simultaneously, can send a plurality of sound in the rotary part rotation process, makes the people be difficult to judge which sound is the tram of lock; In addition, this kind lock is just to having the improvement of lock assembly now, so it does not increase cost, also easily in processing.
Below in conjunction with drawings and Examples the present invention is elaborated.
Accompanying drawing 1 is a cross-sectional view of the present invention;
Accompanying drawing 2 is structural representations of rotary disk among Fig. 1;
Accompanying drawing 3 is vertical views of Fig. 1.
Referring to Fig. 1, it comprises a rotary part 1, and this rotary part can be made into cylinder or cone.During installation, the surface that rotary part 1 end 11 is preferably exposed wing is slightly caught by other apparatus easily preventing.Rotary part 1 just in time can be entangled in fastener 2 middle parts, and rotary part can rotate within it.Rotary part 1 axially extends outward a rotating shaft 12, and this rotating shaft upper area and lower area all are provided with external screw thread 13 and 14, and top screw thread 13 is complementary with the internal thread of securing member 3, and lower thread 14 can be screwed a nut 7.When securing member 3 is screwed in the rotating shaft 12, with screw 4 it closely is connected with fastener 2, rotary part 1, fastener 2 and securing member 3 form a mobilizable integral body at this moment.61 of the upper baffle plates of the soffit of securing member 3 and rotary disk 6 are equipped with a flexure strip 5, in order to limit the position of rotary disk 6.
Rotary disk 6 can be provided with three, all is set with dividing plate 61 between wherein adjacent two rotary disks.Rotary disk 6 operating principles are same as the prior art, no longer elaborate here.Different is that rotary disk 6 peripheries are provided with a plurality of grooves 62, referring to Fig. 2, this groove can be arranged to rectangle or semicircle or other geometry, but a rectangular channel 63 darker than other groove 62 is all arranged on each rotary disk 6, promptly is lock-bit groove of the prior art.When the rectangular channel 63 on three rotary disks 6 all point-blank the time, coded lock promptly is opened.Because rotary disk 6 peripheries are provided with a plurality of equidistant grooves 62, so when rotating, can send a plurality of sound, make again the veteran also be difficult to judge the position which sound is dark rectangular channel 63, thus groove 62 set up the safety that can improve this coded lock greatly.
Referring to Fig. 3, it provides rotary part 1 and fastener 2 outer shape, and their external surface is provided with this scale and character, can determine the position of unblanking according to this degree and character.
