Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing.
In Fig. 1~5：Key 1, lock body 2, screw thread 2-1, go material portion 2-2, housing 3, microswitch 4, lever shell fragment 4-1,
Terminal 5, wiring board 6, steady pin 7, torsion spring 8, spacer pin 9, lock core 10, Slave Block 10-1, locating slot 11, active fast 12, cell body
13。
A kind of elevator ultrathin power lock, including lock body 2, lock core 10, housing 3, lock core 10 are installed on lock body 2, lock body 2
Be connected with housing 3 by steady pin 7, elevator also included with ultrathin power lock torsion spring 8, wiring board 6, terminal 5, microswitch 4,
Key 1, spacer pin 9, steady pin 7, one end of torsion spring 8 are fixedly connected with lock core 10, and the other end of torsion spring 8 is fixed with lock body 2 to be connected
Connect, lock core 10 is flexibly connected with lock body 2, switch lock is realized in the rotation in lock body 2 of lock core 10.Lock body 2 is provided with spacer pin 9, lock core
10 are provided with locating slot 11, and locating slot 11 is the circular arc gap of 90 ° of angle, and spacer pin 9 is connected with locating slot 11, and the structure causes lock
Core 10 can carry out the rotation in the range of 90 degree clockwise, counterclockwise.One end of lock core 10 is another provided with actively fast 12, lock core 10
