Sliding door stopper

Abstract

The invention relates to a sliding door stopper, comprising a drive unit, a front limit switch, a rear limit switch, a sliding unit, and an actuator assembly. The drive unit is connected to a gear. The sliding unit is connected to a stopper bar, a rack, a front actuator, and a rear actuator. The stopper bar is fixed to the end of the sliding unit. The drive mechanism causes the gears to rotate and move, causing the sliding part to slide, so that the stopper can move in or out of the guide groove of the sliding door mechanism. The front and rear limit switches can correspond to the front and rear actuator blocks, respectively. The sensor assembly includes a crank, a rotating shaft, a cam, and a rotating limit switch. The crank transmits motion to the rotating shaft. The cam is fixed on the rotating shaft. When the rotary switch detects the position of the camshaft, the drive mechanism will be activated to operate.
