The invention discloses a hoisting detection device for an air conditioner indoor unit. The hoisting detection device comprises an upper sliding rail
assembly, connecting rods, a lower sliding rail
assembly and suspenders, wherein the upper sliding rail
assembly is arranged above the lower sliding rail assembly, upper sliding grooves are formed in the upper sliding rail assembly, upper sliding blocks are arranged in the upper sliding grooves, the upper end and the lower end of each connecting rod are connected with the corresponding upper sliding block and the lower sliding rail assembly respectively, lower sliding grooves are formed in the lower sliding rail assembly, lower sliding blocks are arranged in the lower sliding grooves, and the lower sliding blocks are connected with the upper ends of the suspenders respectively. According to the hoisting detection device for the air conditioner indoor unit, due to the fact that the upper sliding rail assembly and the lower sliding rail assembly are connected through the connecting rods, the separation distance between every two adjacent suspenders can be adjusted so that the hoisting detection device can be adaptive to the shapes and sizes of different air conditioner indoor units, and the hoisting detection device is simple in structure and low in cost.
