The specific embodiment

A kind of arrangement of clutch of electronic lock, single piece is seen Fig. 1: comprise and isolate axle 1, lock body connecting axle 2 and interior handle connecting axle 5 are formed, it is characterized in that the cavity that lock body connecting axle 2 and interior handle connecting axle 5 are formed, built-in clutch coil axle 3 in chamber and connecting axle 4, see Fig. 2, in the rectangle blind hole of clutch coil axle 3 coil 6 is arranged, see Fig. 3, the hole 11 that coil mandrel 7 passes on clutch coil axle 3 walls is fixed in coil 6 central axiss, coil mandrel 7 two ends are built-in with lock pin 8,8 ', the lead-in wire of coil 6 is drawn from the deep-slotted chip breaker of clutch coil axle 3, the arcuate socket 10 of handle connecting axle 5 in passing.Straight pin 9 vertically is embedded in clutch coil axle 3 and fits in the plane of lock body connecting axle 2, and be higher than clutch coil axle 3 planes, exceed partly just in time consistent with arcuate socket 14 thickness of lock body connecting axle 2, when clutch coil axle 3 rotates, straight pin 9 is done spacing rotation for 14 li at the arcuate socket of lock body connecting axle 2, avoids fractureing when clutch coil axle 3 rotates from coil 6 lead-in wires that interior handle connecting axle 5 is drawn.Connecting axle 4 cylinder ends pass the center hole of clutch coil axle 3 and lock body connecting axle 2, insert in the square blind hole of isolating axle 1, and are outside by cross recessed countersunk head sscrew that lock body connecting axle 2 and interior handle connecting axle 5 is fastening.Outer handle directly is connected with isolation axle 1, can drive clutch coil axle 3 by the axle 4 that is rotationally connected and rotate in the arc spacing hole.

Above-mentioned coil mandrel 7 is a cylinder, its internal diameter is not for isometrical, and there is hole, big footpath at cylindrical two ends, and middle path is a through hole, this reducing through hole makes two ends lock pin conduct magnetism better, and hole, big footpath, the two ends of coil mandrel 7 13 is equipped with fixedly lock pin 8 and fixedly lock pin 8 ' respectively.

Above-mentioned lock pin 8 and 8 ' is the isometrical cylinder of magnetic, can be for various electromagnet, by coil power supply, its diameter is less than the hole, big footpath 13 of coil mandrel 7, lock pin 8 places in the hole in nearly clutch coil axle 3 centers of circle and is fixing, and it is fixing that lock pin 8 ' is arranged in another stomidium 13.

Above-mentioned lock body connecting axle 2 is a cylinder, tube end outside circle centre position has the equilateral four prisms cylinder of evagination, there is circular hole in the center of circle, and arcuate socket 14 is arranged diametrically, and straight pin 9 slides therein, barrel has screw hole on the cross section, the tube internal diameter matches with clutch coil axle 3 external diameters, has a rectangular channel 15 on the tube inwall, and is corresponding with lock pin 8 ', lock pin 8 ' ejects from coil mandrel 7 under "on" position, is limited between this rectangular channel 15 and the coil mandrel 7.

Above-mentioned clutch coil axle 3 is a cylinder, see Fig. 4, there is circular hole in the center of circle, and an overlapping rectangle blind hole 12, and its width equals bore dia, its shape is identical with connecting axle 4 end moment bodies, the square blind hole that internal coil 6 is arranged on diametric plane also has deep-slotted chip breaker, and an end is communicated with square blind hole, the diametric plane opposite side embeds straight pin 9, radially has the circular hole 11 that can put coil mandrel 7 perpendicular to the cylinder outer wall.

Above-mentioned connecting axle 4 profiles are the T-shape body, the perpendicular end of T-shape body is a cylinder, cylinder one end combines with the cuboid stage casing, the end of the other end is equilateral cylinder, match with the overlapping rectangle blind hole 12 in the center of circle in the cuboid of T-shape body end and the clutch coil axle 3, and penetrating path hole, the center of circle, equilateral cylinder inserts isolates in the axle 1 square blind hole, and cooperates with it.

Above-mentioned interior handle connecting axle 5 be equilateral cylindrical body with the disc housing shaft to combining, on the disc housing face arcuate socket 10 is arranged, be used for lead-in wire circle lead, and three Luo silk holes arranged, corresponding with three screw holes on lock body connecting axle 2 column sections.

In conjunction with Fig. 3 description status: when coil 6 is not switched on, the lock pin 8 and 8 ' at coil mandrel 7 two ends is in the attraction state, loose lock pin 8 ' places in the hole, big footpath 13 of coil mandrel 7 fully, clutch coil axle 3 spacing rotation in the cavity that lock body connecting axle 2 and interior handle connecting axle 5 are formed, isolation axle 1 one ends directly are connected the other end with outer handle and are connected with connecting axle 4, outer handle action, can only drive the 3 spacing rotations in cavity of clutch coil axle by connecting axle 4, the handle action also just can not be opened door lock in can not driving.

When coil 6 energisings, the lock pin 8 and 8 ' at coil mandrel 7 two ends is in the repulsion state, loose lock pin 8 ' ejects from the hole, big footpath 13 of coil mandrel 7, be stuck between the rectangular channel 15 of coil mandrel 7 and lock body connecting axle 2 inwalls, make clutch coil axle 3 along with lock body connecting axle 2 moves together, because lock body connecting axle 2 and interior handle connecting axle 5 are fixed by cross recessed countersunk head sscrew, clutch coil axle 3 will drive lock body connecting axle 2 with interior handle connecting axle 5 actions, is connected as a single entity.And the action of clutch coil axle 3 is to drive by connecting axle 4.At this moment the outer handle of action the time, drive a connecting axle 4 that is attached thereto by isolating axle 1, also just driven lock body connecting axle 2 and interior handle connecting axle 5 simultaneously, the interior handle of lock body links to each other with interior handle connecting axle 5, has also just driven interior handle, realizes unblanking.
