Novel PMT probe protection structure

Abstract

A novel PMT probe protection structure disclosed by the present invention comprises a fixed seat, a rotating shaft and springs, the two ends of the fixed seat are fixedly provided with fixing bolts, the two sides of the upper end of the fixed seat are provided with supporting columns, the outer sides of the supporting columns are fixedly provided with fixing rings, the upper ends of the supporting columns are connected with a T-shaped fixing ring, the inner side of the T-shaped fixing ring is provided with the rotating shaft, and a knob is arranged on the outer side of the T-shaped fixing ring. The protection structure of the PMT probe is provided with the springs, the springs are distributed on the inner side of a fixing cylinder in parallel, and the springs fixed between one side of a bottom plate and the bottom of the fixing cylinder provide elasticity for the bottom plate, so that PMT probes with different lengths can be installed on the inner side of the fixing cylinder, and the actual use effect of the protection structure of the PMT probe is greatly improved; and meanwhile, sliding blocks arranged on the two sides of the bottom plate in a matched mode guarantee the position accuracy of the bottom plate in the moving process, an anti-skid layer on the other side of the bottom plate and a soft layer on the inner side of the fixing cylinder can provide a good fixing and protecting effect for the PMT probe, and the service life of the PMT probe is prolonged.

Description

technical field [0001] The invention relates to the technical field of protection structures for PMT probes, in particular to a novel protection structure for PMT probes. Background technique [0002] The PMT probe is a vacuum electronic device that converts weak light signals into electrical signals. It can measure extremely weak radiation power with a wavelength of 200-1200 nanometers in low-level photometry and spectroscopy. The emergence of scintillation counters has expanded the application range of photomultiplier tubes. The development of laser detection instruments is closely related to the use of photomultiplier tubes as effective receivers. The launch and image transmission of TV movies are also inseparable from the PMT probe, and the protective structure of the PMT probe directly affects its actual use effect. [0003] The overall structure of the PMT probe protection structure on the market is not stable and firm enough, and it is easy to shake during actual u...

Problems solved by technology

[0004] The purpose of the present invention is to provide a protective structure of a novel PMT probe, to solve the problem that the overall structure of the PMT probe protective structure proposed in the above-mentioned background technology is not stable and firm enough, and it is easy to shake during actual use and affect the work of the PMT probe. At the same time, the protection structure cannot be adjusted according to the actual use environment, resulting in a small range of use of the protection structure and poor protection effect.
