The invention provides a quick-plug connector installation state inspection tool for a battery thermal management pipeline. The tool comprises a strip groove, an upper cover, a casing, a groove, a side cover, a storage battery, a touch switch 1, a touch switch 2 and a light emitting diode, wherein the upper cover is assembled on the upper end surface of the casing, the side cover is assembled on the right end surface of the casing, the strip groove is opened on the lower side of the inner surface of the casing, the touch switch 2 is assembled at the middle position of the inner side of the strip groove, the groove is formed in the lower side of the front end surface of the casing, the storage battery is assembled in the groove, the touch switch 1 is arranged on the right side of the innersurface of the casing, and the light emitting diode is assembled in the casing. The judgment of a reliable installation state of a quick-plug connector and a lock catch is implemented by using an inspection mode of a profile checking method, so that the defects can be timely inspected and immediately corrected, and the phenomenon that a power battery has various problems or even accidents in the subsequent assembly, experiments or applications can be avoided.
