Description

Technical Field

[0001] The utility model relates to the technical field of protection structures, in particular to a protection structure for a photoelectric detector. Background Art

[0002] At present, most of the existing photoelectric detectors have the advantage of accurate measurement. During use, they generally need to be carried to other places for testing. During the carrying process or use, they are prone to unstable holding, which may cause damage to the instrument due to falling and external force. Therefore, a protective structure for photoelectric detectors is proposed to solve the above-mentioned problems.

[0003] A protective structure for a photoelectric detector is disclosed in the Chinese utility model patent application disclosure CN 210981322 U. The device is provided with a refracting plate. When normal operation is required, the mirror cover on the right side is removed, so that light passes through a concave lens from the right side to reach the refracting plate, and the incoming optical fiber is refracted by the refracting plate and falls on the photoelectric detector through a glass guard plate, so that the photoelectric detector responds to complete normal work. By providing a protective shell and a protective pad, the photoelectric detector will not be damaged by side impact. However, the device needs to detect light in different directions during use, so it needs to be manually rotated, which wastes manpower and material resources and causes inconvenience in use.
