The utility model belongs to the technical field of radioactive measurement devices, and specifically relates to a plastic scintillator detector photomultiplier tube fixing device. The plastic scintillator is bonded to a light guide, and the end face of the light guide and the plastic scintillator is in contact with the light output end face of the plastic scintillator. The other end face of the light guide is made to have the same size as the inner diameter of the connecting sleeve. The light guide and the connecting sleeve are fixedly connected by threads. The connecting sleeve and the socket are fixedly connected by threads. The photomultiplier tube is fixedly connected to the tube base. The socket The sleeve is fixedly connected to the seat cap, and the seat cap is equipped with a BNC socket. The key is that the inner wall of the connector has an inclined wall, and the inclined wall is equipped with a clamp. When the connector is rotated, the connecting sleeve pushes the clamp along the inclined wall. Slide and tighten to secure the photomultiplier tube. There is a rubber bushing inside the clamp to protect the photomultiplier tube. The technical solution provided by the utility model has the advantages of easy installation and disassembly, and is not easy to leak light.
