Abstract
The utility model belongs to the technical field of a radioactive measuring device and particularly relates to a fixing device for a photomultiplier tube of a plastic scintillator detector. A plastic scintillator is adhered to a light guide, and the size of the contacting end surface between the light guide and the plastic scintillator is consistent with that of the light output end surface of the plastic scintillator; the size of the other end surface of the light guide is the same as the inner diameter of a connection sleeve; the light guide is fixedly connected with the connection sleeve through threads; the connection sleeve is fixedly connected with a connection sheath through the threads; the photomultiplier tube is fixedly connected with a tube seat; the connection sheath is fixedly connected with a seat cap through a sheath cap; and a BNC (bayonet nut connector) socket is arranged on the seat cap. The key points of the fixing device are as follows: an oblique wall is arranged on the inner wall of the connection sheath, and a hoop is arranged at the position of the oblique wall; when the connection sheath is rotated, the connection sleeve pushes the hoop to slide and shrink along the oblique wall, so as to fix the photomultiplier tube. A rubber bushing arranged at the inner side of the hoop can protect the photomultiplier tube. The provided fixing device which adopts the above technical scheme has the advantages of being convenient to assemble/disassemble and not easily leaking light.
