Description
Technical Field
The invention relates to the technical field of metal lenses, in particular to a metal lens cover structure with multiple opening angles.
Background
The objective glass or ocular glass of various optical instruments (professional cameras, microscopes, telescopes, sighting telescope and the like) is exposed on one side, dust and water are easily attached to the objective glass or ocular glass, the dust and the water are attached to the lens glass to affect the observation of a user, and the glass is corroded or mildewed to affect the optical performance of the optical instruments in serious cases. These specialized optical instruments are therefore typically equipped with lens covers to provide everyday dust and water protection for the objective or eyepiece. The objective lens and the ocular lens of the white light sighting telescope are generally protected by a lens cover in a dustproof and waterproof way.
At present, the lens cover mainly has two types, namely a detachable type and a fixed type. The detachable lens cover has three structures: one is to cover the lens on the screw thread of the inner hole at the front end of the lens; the other lens cover is clamped in an inner hole at the front end of the lens by an elastic bayonet; the other type is that a plastic lens cover is sleeved on the excircle of the front end of the lens, the plastic lens cover is used on a white sighting telescope more frequently, and the plastic lens cover generally connects the objective lens cover and the eyepiece lens cover together by two elastic cords so as to ensure that the lens cover is tightly attached to the end surface of the lens to prevent dust and water. The detachable lens cover is inconvenient to disassemble and assemble due to the time, and the detachable lens cover needs to be stored in a certain place, so that the two defects are particularly remarkable for the white sighting telescope used in the field.
