Description

Technical Field

[0001] The utility model relates to the technology of helmet inspection and measurement, and specifically, to a multifunctional inspection and measurement tool for bulletproof helmets. Background Art

[0002] In today's security field, bulletproof helmets play a crucial role. To ensure that their quality and performance meet strict standards, precise measurement is an essential step.

[0003] Currently, for the measurement of the major axis, minor axis, and depth of bulletproof helmets, traditional measuring tools such as calipers, tape measures, and micrometers are mainly relied on. However, these measuring tools and methods have obvious defects. First, due to the diversity of measuring tools, it is difficult to unify the measurement standards, and different tools and operation methods will lead to differences in measurement results. For example, when using calipers for measurement, the selection of measurement points and the magnitude of the applied force may vary from person to person, thus affecting the measurement accuracy; when using a tape measure to measure a curved or irregular surface, it is prone to errors.

[0004] Furthermore, the problem of the brim height of the helmet also brings difficulties to the measurement. The presence of the brim will interfere with the line of sight, making it easy to have deviations in the readings. During the measurement process, it may be necessary to repeatedly adjust the measurement angle and position to obtain relatively accurate values, but this still cannot completely avoid errors.

[0005] It should be noted that the tolerance requirements for bulletproof helmets are usually within the range of ±2mm. This relatively small tolerance range makes it easy for small deviations in the measurement results to lead to the helmet being judged as unqualified from qualified, bringing great challenges to production and quality control.

[0006] In summary, there are many problems with the existing measuring tools in the measurement of multifunctional bulletproof helmets, which not only affect the measurement accuracy and efficiency but also are difficult to meet the strict quality control requirements. Therefore, it is imperative to develop a dedicated and multifunctional inspection and measurement tool. Content of the Utility Model
