Abstract: A shaft-grounding bearing protection device and a motor are provided. The shaft-grounding bearing protection device includes a device body of a ring shape, a side wall of the device body is provided with at least one mounting hole, the mounting hole is a first direction directing toward the center of the device body and radially penetrating through the device body; and a conductive fiber passing through the mounting hole provided on the device body, an extension direction of the conductive fiber is toward the center of the device body. When the conductive fiber passes through the mounting hole, a clamping force in a second direction of the mounting hole is adjusted to realize the crimping of the conductive fiber and the device body, and the second direction is perpendicular to the first direction.

Abstract: The present invention relates to a landing-door door lock device. The following problem is solved: the position of a lock ball of a general landing-door door lock device is not adjustable, and adjustment is complicated when there is a deviation between positions of the lock ball and a door knife.
