The invention discloses a chain loose prevention device, comprising a chain, a pressing block, an upper shaft, a lower shaft, a support, a baffle plate, and a microswitch. The front side of the pressing block is pressed on a side of the chain. The front ends of the upper shaft and the lower shaft are respectively fixedly connected with the rear side of the pressing block. The baffle plate is fixed on the rear end of the upper shaft and the lower shaft. The support is installed on the upper shaft and the lower shaft, and can move front and back along the upper shaft and the lower shaft. The support is between the pressing block and the baffle plate. Compression springs are respectivey sleeved on the upper shaft and the lower shaft between the pressing block and the support. The microswitch is installed on the support and is below the baffle plate. The microswitch is connected in a power supply circuit of a mechanical parking device. The chain loose prevention device is reasonable in structure, and prevents a vehicle from falling and being damaged in a lifting process caused by faults of a chain of a mechanical parking device, so that the device ensures safe lifting of vehicles.
