The specific embodiment

As shown in Fig. 1 ~ Figure 10, a kind of mechanical code lock, comprise face-piece 1 and drain pan 2, face-piece 1 is fixedly connected with drain pan 2, in the present embodiment, face-piece 1 and drain pan 2 are screwed connection, facilitate the dismounting of face-piece 1 and drain pan 2, face-piece 1 and the inner spatial accommodation that forms of drain pan 2, described spatial accommodation is provided with cover plate 9, wheel shaft 10, clutch block 7, briquetting 3, movable block 8, latch hook 14, the lock-opening closing mechanism of controlled lockmaking hook 14 foldings and the lock dog 24 that can order about lock-opening closing mechanism motion, lock dog 24 is fixedly connected with movable block 8, concrete, on case and bag, be equiped with slide fastener, when the case lid of case and bag and casing fasten, slide fastener stretches in latch hook 14 also locked, now case and bag are lockable, movable block 8 is slidably connected with cover plate 9, movable block 8 can slidably reciprocate along cover plate 9, described wheel shaft 10 outsides are arranged with successively and adjust code block 23 along axis, adjust code wheel 11 and back-moving spring 25, wheel shaft 10 is provided with slurcam 105, the two ends of back-moving spring 25 are supported respectively and are adjusted code wheel 11 and slurcam 105, slurcam 105 and movable block 8 are supported clutch block 7 respectively at homonymy, clutch block 7 is provided with the first straight inclined-plane 72, briquetting 3 is provided with the second straight inclined-plane 32 that can be slidably connected with the first straight inclined-plane 72, concrete, the motion process of brief description briquetting 3, while pressing briquetting 3, briquetting 3 moves downward, the straight inclined-plane 32 of in briquetting 3 second can apply a lateral force left to the first straight inclined-plane 72 of clutch block 7, this lateral force is ordered about clutch block 7 to left movement, the epimere part of clutch block 7 and hypomere partly promote respectively slurcam 105 and movable block 8 to left movement, because wheel shaft 10 is now pinned and can not move by password, slurcam 105 on wheel shaft 10 stops clutch block 7 to left movement, thereby movable block 8 also cannot be unblanked to order about lock-opening closing mechanism control latch hook 14 to left movement, the process of unblanking of brief description password, adjust code wheel 11 inner sides to be provided with the first projection 112, wheel shaft 10 be respectively equipped with the chute 108 that can slide for the first projection 112 and can with the draw-in groove 106 of the first protruding 112 clampings, described chute 108 forms an intersection 107 with draw-in groove 106, wherein, when the first projection 112 is positioned at chute 108, wheel shaft 10 can be free to slide vertically, wheel shaft 10 is in free state, when the first projection 112 is positioned at draw-in groove 106, wheel shaft 10 is locked, wheel shaft 10 can not be free to slide vertically, described tune code wheel 11 outer faces are arranged with cipher wheel 4, cipher wheel 4 inner sides are provided with slot 41, adjust code wheel 11 to be provided with second projection 111 that can be plugged in slot 41, concrete, adjust the slot 41 of the second projection 111 insertion cipher wheel 4 of code wheel 11, adjust code wheel 11 and cipher wheel 4 by the second projection 111 of arranging and slot 41 realize mutual circumferentially fixing and can be along the circumferential direction together with rotate, in cipher wheel 4, be provided with numeral, when latch hook 14 is locked, the first projection 112 of adjusting code wheel 11 inner sides to arrange is positioned at the draw-in groove 106 of wheel shaft 10, wheel shaft 10 is blocked and can not move freely by the first projection 112, while unblanking, by the password rotational password arranging, take turns 4 to tram, now adjust code wheel 11 also with cipher wheel 4, to rotate, the first projection 112 of adjusting code wheel 11 inner sides to arrange is turned to the position that crosses of chute 108 and draw-in groove 106, the first projection 112 can be slided along chute 108, thereby wheel shaft 10 vertically left and right is free to slide, when pressing clutch block 7, wheel shaft 10 slides left with clutch block 7 under the effect of slurcam 105, movable block 8 also slides left under the promotion of clutch block 7 hypomere parts, movable block 8 drives lock dog 24 to order about lock-opening closing mechanism control latch hook 14 and unblanks, thereby latch hook 14 is opened, unclamp briquetting 3, slurcam 105 promotes clutch block 7 and back moves under the effect of back-moving spring 25, wheel shaft 10 is back motion also, until the first projection 112 on tune code wheel 11 is positioned at the position that crosses of chute 108 and draw-in groove 106, rotational password wheel 4 is to other positions, cipher wheel 4 drives adjusts code wheel 11 to rotate, thereby the first projection 112 and draw-in groove 106 clampings, wheel shaft 10 is locked again, the alter operation process of brief description password, described spatial accommodation is also provided with adjusts code switch 5, adjust code switch 5 to be provided with the 3rd straight inclined-plane 51, adjust code block 23 to be provided with the 4th straight inclined-plane 231 that can be slidably connected with the 3rd straight inclined-plane 51, described face-piece 1 is provided with slide fastener jack 104, can distinguish accommodating cipher wheel 4, adjust the cipher wheel hole 102 of code switch 5 and briquetting 3, adjust code switch hole 103 and pressing hole 101, concrete, press and adjust code switch 5, adjust the 3rd straight inclined-plane 51 on code switch 5 to apply a thrust to the right to the 4th straight inclined-plane 231 of tune code block 23, this thrust to the right promotes to adjust code block 23 to slide to the right, adjust code block 23 also to promote to adjust code wheel 11 to slide to the right simultaneously, because the upper end of cipher wheel 4 is placed in cipher wheel hole 102, cipher wheel 4 axial restraints, while adjusting code wheel 11 to slide to the right, adjust the second projection 111 of setting on code wheel 11 from the interior disengaging of slot 41 of cipher wheel 4, now cipher wheel 4 can circumferentially be rotated again, user as required rotational password wheel 4 carries out the change of password, then unclamp and adjust code switch 5, adjust code wheel 11 back motion under the effect of back-moving spring 25, adjust the second projection 111 on code wheel 11 to insert again in the slot 41 of cipher wheel 4, cipher wheel 4 is fixed again at circumferencial direction, cipher wheel 4 can be rotated together with adjusting code wheel 11.By the briquetting 3 and the clutch block 7 that arrange, briquetting 3 and clutch block 7 are slidably connected by straight inclined-plane, press briquetting 3, clutch block 7 promotes lock dog 24 and controls unblanking of lock-opening closing mechanism under the effect on the straight inclined-plane cooperatively interacting, by the mode of pressing, realize unblanking of the utility model mechanical code lock, it is simple in
