Description

Technical Field

[0001] The utility model relates to the technical field of lens protection, in particular to a lens protection device for a measuring instrument. Background Art

[0002] The measuring instrument lens is an important component of the measuring instrument. It is used to magnify and focus the object to be measured for accurate measurement. The measuring instrument lens is generally composed of multiple lenses. The magnification and focusing distance can be changed by changing the distance between the lenses or replacing lenses with different focal lengths.

[0003] Different measuring instruments may require different types of lenses. However, most existing measuring instruments leave their lenses exposed during use, and some do not have specific protection for them. However, when not in use, they are easily damaged by collisions, and in severe cases, the internal part of the lens may be damaged, thereby reducing the safety protection of the device. In addition, the measuring instrument may always be affected by light during use, resulting in a significant impact on the lens, which will also reduce the measurement effect. Therefore, it is urgent to solve the above problems. Utility Model Content
