The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Embodiment:

As shown in Figure 1, Figure 2, Figure 3 shows, the present embodiment provides a kind of coded lock, comprises password box 1, movable pin key, fixation steel plate with holes, an installing plate and a cylinder plate 2, described movable pin key, fixation steel plate with holes, an installing plate and a cylinder plate 2 with holes are all placed in password box 1, the upper end of described password box 1 is provided with surface plate with holes 9, lower bottom is provided with non-porous pads base plate 10, described movable pin key divides effective key 7 and invalid key 15, said fixation steel plate with holes comprises all-pass orifice plate 3 and invalid key plunger ventilating hole plate 4, installing plate is arranged between all-pass orifice plate 3 and invalid key plunger ventilating hole plate 4, described password box 1 inner chamber is separated out a plurality of keyways 6 by polylith dividing plate 5 by all-pass orifice plate, effectively key 7 is arranged in keyway 6, the invalid key plunger ventilating hole plate 4 being positioned at the bottom of password box box is provided with the keyhole 8 of placing invalid key, described cylinder plate 2 is provided with all-pass hole 21 and hole slot 22, the two setting arranges by password facilities, described effective key 7 is positioned at hole slot 6, invalid key 7 is conflicted through all-pass hole 22 and non-porous pads base plate 10.

Described installing plate is for the U-shaped plate of portable coded lock or for two parallel levers (figure is all not shown) of fixed coded lock, by password box and elastic wire rope, formed for portable coded lock, for fixed coded lock, by password box, active plugboard, plugboard trough and the pull bar that is connected with active plugboard, formed; Be convenient to identification and surface plate 9 described in password be set be provided with the 91 minutes letter or numbers in indicator around, numeral is by 0 to 9 or 26 English alphabet, as seen from the figure, as " ABC0 " is a cryptographic key, need prompting simultaneously be occur arranging in password if there is 4 above-mentioned letter or numbers wherein one or more be all effective key, otherwise do not appear as invalid key, concrete password needs client oneself to arrange as required.
