Description

Technical Field

[0001] The utility model relates to the technical field of infrared thermal imagers, and particularly relates to a housing of an infrared thermal imager. Background Art

[0002] An infrared thermal imager uses an infrared detector and an optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflects it onto the photosensitive element of the infrared detector, thereby obtaining an infrared thermal image. This thermal image corresponds to the thermal distribution field on the surface of the object. Generally speaking, an infrared thermal imager converts the invisible infrared energy emitted by an object into a visible thermal image.

[0003] In the prior art, the housing of an infrared thermal imager lacks a structural design specifically for fixing internal components, resulting in unstable installation of components. During use, loosening or displacement is likely to occur, affecting the normal working performance and accuracy of the instrument.

[0004] The traditional housing of an infrared thermal imager has the problem that the front cover and the rear cover are difficult to disassemble, which makes the installation, maintenance and replacement of internal components extremely difficult, increasing the maintenance cost and time. At the same time, for some parts that need to be frequently operated or connected to external devices, there is no convenient opening or movable structure, resulting in inconvenient operation.

[0005] The housing of the infrared thermal imager in the prior art has defects in structural strength and cannot effectively withstand external pressure and impact, easily causing damage to internal components. In addition, poor heat dissipation performance is also a common problem, which will cause the instrument to reduce its performance, shorten its service life or even malfunction due to overheating during operation.

[0006] The previous housing of an infrared thermal imager did not have a standardized size design, and the size differences of the housings of different manufacturers or models were relatively large, which made the compatibility of the products poor. Summary of the Utility Model
