In the first clamping hole 621 , four radially concave and equiangular interlocking recesses 622 are provided on an outer ring surface 620 of the interlocking member 62 . On the induction part 63, there is a disc-shaped fastening part 631, and a sensing part 632 extending radially from the fastening part 631, and a second snap-fitting part 631 is provided on the fastening part 631 to engage with the lever part 612. hole 633 , and the sensing part 632 can be driven by the control rod 61 to move between the two sensing parts 51 , 52 .

The electric control device 7 is installed in the chamber 43 of the base 4, and it has a motor 71 providing power, a worm wheel 72 fixed on an axis of the motor 71, and an engaging gear 73 meshed with the worm wheel 72 .

The clutch device 8 is movably sleeved on the control rod part 612 of the control rod 61, and can transmit the power of the motor 71 to the control rod 61. The above-mentioned clutch device 8 has a positioning seat 81, and two positioning seats 81 are fixed on the base. The screw rod 82 on the two frame tubes 413 of the seat 4, a clutch seat 83, and four clutch units 84, wherein the positioning seat 81 has a disc-shaped body 811, and extends from the top of the body 811 for the screw rod 82 to pass through The two wings 812 of the body 811 define a circular perforation 814 by means of an inner ring surface 813, and four positioning recesses 815 recessed toward the outer ring surface of the body 811 are provided at equiangular positions on the inner ring surface 813.

The clutch seat 83 is also sleeved on the lever portion 612 of the lever 61. The above-mentioned clutch seat 83 has an engaging portion 831 meshing with the engagement gear 73, and a shaft protruding from the engaging portion 831 to the perforation 814 of the positioning seat 81. Tube portion 832, and a through hole 833 that runs through the engaging portion 831 and the shaft tube portion 832, wherein, the shaft tube portion 832 has an outer ring surface 834 that forms a distance between the inner ring surfaces 813 of the positioning seat 81, and the outer ring surface 834 on the outer ring Four equiangular installation slots 835 are radially recessed on the surface 834 , and each installation slot 835 includes an outer opening 836 , an inner opening 837 , and a shoulder 838 between them. And these clutch units 84 are respectively installed in each installation groove 835, and each clutch unit 84 all comprises a spring 841 and a positioning pin 842 abutting on the shoulder 838, wherein, the length of the positioning pin 842 is slightly longer than The installation groove 835 has a circular arc positioning end 843 protruding from the outer opening 836 and a linkage positioning end 844 protruding from the inner opening 837 to the through hole 833 .

As shown in Figures 2 and 3, after the electric lock 1 of this embodiment is installed, the sensing part 632 of the sensing piece 63 is located beside the photoelectric switch 51. Part 62 is arranged inside and outside, therefore, each mounting groove 835 on the clutch seat 83 will correspond radially to each positioning recess 815 on the positioning seat 81, and is pushed by each spring 841, and the circular arc positioning ends of these positioning pins 842 843 protrudes and is positioned in the positioning recess 815 of the positioning seat 81, and is located in an unlinked position.

When this embodiment is controlled by manual control, the rotary control part 611 of the control lever 61 is held by hand and rotated. When the control lever 61 rotates, the linkage piece 62 and the induction piece 63 which are matched with it will move without resistance. Rotate accordingly in the state, until the sensing portion 632 of the sensing piece 63 corresponds to another photoelectric switch 52, at this time, the clutch seat 83 is engaged with the positioning seat 81 and fixed without rotation by means of the support of each clutch unit 84 . That is to say, under the manual operation, each clutch unit 84 is located at the unlinked position.

As shown in Figures 4 and 5, when this embodiment is operated in an electronically controlled manner, first start the motor 71, and the motor 71 can drive the worm gear 72 and the connecting gear 73 to rotate, and when the connecting gear 73 rotates, it will drive the clutch seat of the clutch 83 rotates according to the set direction. When the clutch seat 83 rotates, the inner ring surface 813 of the positioning seat 81 protrudes from the positioning recess 815, and the positioning pin 842 will overcome the elastic force of the spring 841 and retract radially into the mounting groove 835. Because the length of the positioning pin 842 is slightly longer than The depth of the mounting groove 835 of the clutch seat 83, therefore, the interlocking positioning end 844 of the radially inwardly moving positioning pin 842 will stretch into the through hole 833, and be inserted into the interlocking recess 622 of the interlocking piece 62, and be in the interlocking position. In the moving position, since the linkage 62 is linked with the control lever 61 and the induction strip 63, it will drive the control lever 61 and the induction strip 63 to rotate until the induction part 632 on the induction strip 63 corresponds to another photoelectric switch 52. That is to say, the clutch device 8 of this embodiment only produces interlocking relationship when it is electronically controlled, and only the manual control device 6 rotates when it is manually controlled, so this embodiment has nothing to do with the clutch device 8 on the manual operation, so it is very labor-saving .

As shown in Figures 6 and 7, the second embodiment of the electric lock 1 of the present utility model includes not only a lock control device, a lock key device, and a door handle device not shown in the figure, but also includes: a base 4, two photoelectric switches 51, 52, the hand control device 6, the electric control device 7 and the clutch device 8, wherein the hand control device 6 also has a linked control lever 61, a link piece 62 and an induction plate 63, and one side of the link piece 62 Four interlocking recesses 622 are arranged at equal angles on the ring surface. The clutch device 8 also has a positioning seat 81, two screw rods 82 for fixing the positioning seat 81, a clutch seat 85 fitted with the positioning seat 81, and four clutch units 86, wherein the positioning seat 81 is the same as that of the first embodiment. Same, but there are four positioning recesses 815 arranged at equal angles, four installation grooves 851 are cut out on the clutch seat 85, and each installation groove 851 has a fixed part 852 and an outlet part 853 cut radially. and a connecting portion 854 connecting the two. The clutch unit 86 is an elastic shrapnel itself, and the above-mentioned clutch unit 86 has a fixed section 861 positioned on the fixed part 852, a moving section 862 that can move radially in the outlet part 853, and a moving section 862 connected to the moving section 862. And the elastic storage section 863 on the fixed section 861, wherein the moving section 862 further has a linkage positioning end 864 and a circular arc positioning end 865 which are far away from each other.

As shown in Figures 7 and 8, under normal conditions, the arc positioning ends 865 of the clutch units 86 will extend into the positioning recesses 815 of the positioning seat 81, and when the electric control device 7 drives the clutch seat 85 to rotate, it will be positioned. Pushing an inner ring surface 813 on the seat 81, the arc positioning ends 865 of the clutch units 86 will be pushed into the inner ring surface 813, and at this time, the linkage positioning ends 864 will protrude to each of the linkage parts 62. The recess 622 is linked, and thus the manual control device 6 is linked. When the control lever 61 is rotated in a manual operation, since the linkage positioning ends 864 of each clutch unit 86 retract into the outlet portion 853 of the clutch seat 83, the control lever 61 will only drive the linkage piece 62 and the sensing piece 63 rotations, like this, can make manual operation labor-saving.
