The utility model relates to the technical field of inspection robots, in particular to an anti-collision indoor inspection
robot, which comprises a movable base, a monitoring head main body, a camera, a
camera module, a
camera module, a
camera module and a camera module, and is characterized in that the top surface of the movable base is provided with a monitoring head main body; a movable groove is formed in the side wall of the movable base, and an
insertion groove is formed in the bottom face of the movable groove. And a protection structure is installed on the movable base and comprises an annular plate, the annular plate is movably installed on the inner side of the movable groove, a
coil spring is fixedly connected to the inner wall of the annular plate, and an annular frame is rotatably installed on the outer wall of the annular plate through a bearing. The annular
coil spring is arranged on the inner side of the annular plate, and the
coil spring is sleeved on the inner side of the movable groove, so that when the annular plate moves at any angle in the plane direction on the inner side of the movable groove, the coil spring can be extruded, the coil spring is elastically deformed, the moving trend of the annular plate is slowed down, the action strength on the device can be reduced, and the service life of the device is prolonged. The use experience of the device is prolonged.
