Specific embodiment

With reference to the accompanying drawings and examples the present invention is further described.

Fig. 1 is the stereogram of coded lock of the present invention, and foot is code-disc 1, and it is circular thin slice, thickness 2 to 4mm it Between, upper surface is printed on the graduation mark of circumference uniform distribution, in the present embodiment by taking 24 lattice graduation marks as an example.It is knob 3 and lock on code-disc 1 Body 2.Lock body 2 is columned, and four legs 12 and the code-disc 1 of lock body 2 are fixed together by the screw at the back side of code-disc 1.Top The locking closure 4 in portion is rotated with lock body 2 by rotating shaft 5 and is connected.The inside of lock body 2 arranges rotatable cipher ring, the tenon 16 of locking closure 4 to Extend in lock body 2 and be engaged with cipher ring, active body is set on knob 2, arrange on cipher ring by kinetoplast, knob 3 is rotated and made Obtain active body to promote by kinetoplast, and then cipher ring is rotated, to block or discharge the tenon 16 of locking closure 4, so that locking closure 4 is pinned or solved Lock.In the present embodiment, active body and block is by kinetoplast；Active body and can also be tied using plate body or spheroid etc. by kinetoplast Structure.

Fig. 2 is the top view of coded lock of the present invention, it can be seen that lock body 2 has four legs 12.

In Fig. 3, uniform 2 to 8 blind holes of the lower circumference of knob 3 have a spring 6 and a steel in each blind hole Pearl 7.The corresponding pit 13 for being provided with a circle circumference uniform distribution on code-disc 1, quantity, position with code-disc 1 on graduation mark one Cause.When turning knob 3, steel ball 7 can allow user to produce pause and transition in rhythm or melody sense in the presence of spring 6, even if not seeing code-disc 1, make User can also perceive and oneself have rotated how many scales.Meanwhile, sound is always produced when steel ball 7 falls each pit 13, So increase the difficulty of irrelevant personnel's unblock.

As can be seen that the inside of lock body 2 has upper cipher ring 8 (i.e. first password ring), (i.e. second is close for middle cipher ring 9 in Fig. 4 Code ring).As shown in figure 5, cipher ring is a kind of split ring of c-type, similar to axle split washer.And corresponding in lock body 2 have Shallow grooves 15, cipher ring is arranged in groove 15, and each cipher ring can freely be rotated in lock body 2.On each cipher ring There is the waist-shaped hole 14 of circle distribution, on the angle and code-disc 1 between each two waist-shaped hole 14 between two neighboring graduation mark Angle is consistent.Also there is the waist-shaped hole 14 of circle distribution above knob 3.The purposes of waist-shaped hole 14 is to place block 10.

In Fig. 6, the inner ring of lock body 2 has circumferential groove 15, coordinates with upper cipher ring 8 and the gap of middle cipher ring 9, two passwords Ring both can be rotated freely because being c-type structure, therefore can be placed in the circumferential groove of lock body 2, and also ensuring that to take off Fall.

Fig. 7 is locking closure of the present invention 4, upper cipher ring 8, middle cipher ring 9, the sectional view of knob 3.Upper cipher ring 8 and middle password In shown position, the tenon 16 under the rotating shaft 5 of locking closure 4 is blocked ring 9 by two cipher rings, therefore locking closure 4 cannot be opened.And And as long as any one cipher ring has blocked tenon, locking closure 4 all cannot be opened.

Block 10 is all embedded on upper cipher ring 8, middle cipher ring 9 and knob 3.The block 10 of upper cipher ring 8 is stretched out in down Side, the upper and lower of middle cipher ring 9 has all stretched out block 10, and block 10 is stretched out in the top of knob 3.The block 10 of the top of knob 3 is with The block 10 of the lower section of cipher ring 9 is arranged on same circumferential position, block 10 and the lower section of upper cipher ring 8 of the top of middle cipher ring 9 Block be arranged on same circumferential position.When user's turn knob 3 is more than 1 circle, no matter which position middle cipher ring 9 is located at Put, the block 10 of the lower section of middle cipher ring 9 can mutually be touched with the block 10 of the top of knob 3, be screwed 3 drives and rotated together.When When middle cipher ring 9 rotates over a circle, cipher ring 8 no matter is gone up in which position, all can be by the block 10 of the top of middle cipher ring 9 It is rotated.

As shown in Fig. 5,7,8, side relative with c-type structural openings 19 on upper cipher ring 8 arranges gap 18, gap 18 with The coupler body 17 that the bottom of locking closure 4 is arranged is engaged, and coupler body 17 is relative with the position of the tenon 16 of locking closure 4.

Coupler body 17 is of an L-shaped structure, and the base cocker of L-type structure lives in the bottom surface of cipher ring 8.

4 times coupler bodies 17 plus a L-type of locking closure, when knob is to locked position, the tenon at the rotating shaft of locking closure 4 16 can block cipher ring 8, and the coupler body 17 under locking closure 4 can also block cipher ring 8, and such locking closure is difficult to be pried open. Upper cipher ring 8 is relative with opening 9 gap 18, when upper cipher ring 8 turns to open position, the alignment card of opening 19 Bamboo shoot 16, the alignment coupler body 17 of gap 18, coupler body 17 can not again block cipher ring 8.Now, locking closure can be what is be opened.So Just can will not be pried open with dual guarantee locking closure, be enhanced the security of locking closure.

According to such principle, when using, knob 3 is first rotated forward or inverted and initialized more than two circles.Knob 3 is now Cipher ring 8 can have been driven to rotate.According to the instruction of password, knob 3 first turns an angle, and allows the opening of cipher ring 8 Mouth targeted by the tenon 16 of the lower section of rotating shaft 5 of locking closure 4.Then knob 3 is inverted more than a circle, and the block 10 of the top of knob 3 is from another The block 10 of the lower section of middle cipher ring 9 is touched in side, then proceedes to rotating in same direction certain angle, makes the opening of middle cipher ring 9 also right The tenon 16 of quasi- locking closure 4.So, the opening of two cipher rings all targeted by tenon, and when opening locking closure 4, tenon is not obstructed Hinder, the gap 18 of upper cipher ring 8 targeted by the coupler body 17 of locking closure 4, and coupler body 17 is unobstructed, and locking closure 4 can be opened.

By taking an embodiment as an example, specific operation process is as follows：

There is 0 graduation indication to identify for reference on knob 3.User first turns clockwise more than 3 liang of circles of knob, allows Directly over 0 graduation indication on knob 3 is pointed to, that is, complete initialization.Now, under the block 10 on knob 3 and middle cipher ring 9 Block 10 is touched.The block 10 of the top of middle cipher ring 8 is touched with the block 10 under upper cipher ring 8.Then start input to set in advance Fixed password.If password is 8-26, first lap first turns clockwise 8 lattice, and knob 3 can drive cipher ring 8 to be rotated further At the opening of supreme cipher ring 8 and the tenon 16 of locking closure 4.Then the lattice of 3 rotate counterclockwise of knob 26, have to be larger than counterclockwise 24 lattice The reason for be the block 10 for needing the block 10 of knob 3 to touch from opposite side under middle cipher ring 9, can just drive its inverse time Pin rotates.And now, block 10 and the block 10 of the lower section of upper cipher ring 8 of the top of middle cipher ring 9 are to disengage.Knob 3 drives Middle cipher ring 9 turns to the tenon 16 of the opening alignment locking closure 4 of middle cipher ring 9.Now, the opening of two cipher rings all targeted by Tenon, the gap 18 of upper cipher ring 8 also targeted by the coupler body 17 of locking closure 4, and locking closure 4 can be opened.

In Fig. 9, a kind of double lockset, in the outer suit of lockset 11 coded lock as above, forms lock the dual of external lock and opens Lock mode.First coded lock must be opened with proper password, opening locking closure 4 can just see the lockset 11 of inside, use key operated lock Tool 11, and then open the door of rack or cabinet.
