Description

Technical Field

[0001] The utility model relates to the technical field of testers, in particular to a handheld anti-fall radiation measuring instrument. Background Art

[0002] The radiation meter is a new type of portable, intelligent xγ penetrating radiation dose rate meter. It is made of the latest powerful single-chip microcomputer technology and uses a semiconductor detection device. It has the characteristics of high sensitivity, easy operation, automatic display, data storage of high threshold historical values, etc. It can give the measurement results in real time and the cumulative dose received by an individual. It is widely used in geological surveys and explorations, radioactive waste repositories, industrial non-destructive testing, hospital γ knife treatment, isotope application, γ irradiation, hospital X-ray diagnosis, cobalt treatment, nuclear power plants and other radioactive places. For example, the patent with publication number CN219475843U discloses an anti-fall handheld nuclear radiation meter, including a measuring instrument body, a front side of the measuring instrument body is fixedly installed with an anti-fall column, a front side of the measuring instrument body is fixedly installed with an operation button, a bottom of the measuring instrument body is fixedly installed with a handle assembly, a back side of the handle assembly is fixedly installed with a counterweight hand guard, a back side of the measuring instrument body is fixedly installed with a buffer spring, and a protective plate is fixedly installed at one end of the buffer spring away from the measuring instrument body. The device has multiple anti-fall columns fixedly installed on the front of the measuring instrument body, and a counterweight guard fixedly installed on the back of the handle assembly. When the operator accidentally lets go of the handle and causes the measuring instrument to fall, the counterweight guard will not cause the heavier end of the measuring instrument body to hit the ground but will keep descending horizontally. At the same time, a protective plate and a buffer spring are installed on the back of the measuring instrument body to protect the measuring instrument. However, when the measuring instrument falls to the ground, although the measuring instrument will not fall directly on the ground, it will be subjected to a certain elastic force after falling, which may cause the measuring instrument to flip over, causing the front of the measuring instrument to directly contact the protrusion on the ground, thereby causing damage to the measuring instrument.

[0003] To this end, the utility model provides a handheld anti-fall radiation measuring instrument. Utility Model Content
