Description

Technical Field

[0001] This utility model relates to the field of sun protection testing instruments, and in particular to a fabric ultraviolet sun protection testing instrument with adjustable irradiation angle. Background Technology

[0002] With global warming and increasing ultraviolet radiation, people's demand for sun protection products is becoming more and more urgent. As textiles are items that come into direct contact with human skin in daily life, their sun protection performance has attracted much attention. Ultraviolet sun protection testers can comprehensively and accurately simulate ultraviolet radiation under actual use scenarios according to different testing needs, providing more reliable data support for the evaluation of fabric sun protection performance.

[0003] In the early days, the sun protection performance of fabrics was tested by directly exposing the fabric to sunlight and observing the difference in sunburn on human skin in areas covered and uncovered by the fabric to roughly judge the fabric's sun protection effect. However, this method was highly subjective, greatly affected by environmental factors, and could not accurately quantify the sun protection performance of the fabric. Gradually, some simple testing instruments emerged, but these instruments had limited functions and could not simulate ultraviolet radiation from different angles. In real life, the angle of sunlight is constantly changing, so the test results deviated from actual usage. Utility Model Content

[0010] The adjustment component includes a worm gear, which is disposed between two adjacent mounting blocks. One end of the worm gear is equipped with a motor, and the bottom surface of the motor is fixedly connected to the bottom surface of the inner wall of the housing.

[0011] As a further description of the above technical solution:
