| description | The utility model discloses a domestic small elevator speed governor which comprises a rack (1), a rope wheel (2), a disc (3), a rotating shaft, a travel switch (4) electrically connected with a traction machine and an electromagnet (5) used for resetting the travel switch (4), the rope wheel (2) and the disc (3) are rotationally connected to the rack (1) through the rotating shaft, and when the speed governor is in a triggering state, the electromagnet (5) resets the travel switch (4). The disc (3) rotates to enable the side wall of the notch (3.1) to push the driving rod (8) so as to trigger the travel switch (4); and in a reset state, the electromagnet (5) drives the switch pulling plate (7) and pulls the driving rod (8) to reset the travel switch (4). The speed limiter of the household small elevator adopts an electromagnet structure to reset the travel switch through the linear telescopic motion of the piston rod, and is simple in structure and good in reliability.
