Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical lenses, in particular to a large-size high-uniformity optical lens based on vapor deposition technology. BACKGROUND

[0002] Optical lenses usually need to use vapor deposition technology for lens coating to make the lens work normally. The applicant found through retrieval that a multi-focal optical lens with application number 202422431881.4 includes a multi-focal lens body, a protective cover on the outer side of the multi-focal lens body, an outer shell threadedly connected to the bottom end of the protective cover, first sealing rings fixed in the protective cover and the outer shell, the multi-focal lens body between the two first sealing rings, a first stop block integrally formed on the outer wall of the protective cover, a connecting block in the first stop block, an insertion block integrally formed on the side of the connecting block away from the protective cover, a second stop block integrally formed on the outer wall of the outer shell, an insertion slot on the second stop block adapted to the insertion block, a pressure rod above the insertion block, a spring on the pressure rod, and the pressure rod penetrating through the first stop block and connected to the connecting block at the end close to the protective cover. However, the protective cover first sealing ring needs to be rotated during installation, which may cause friction on the lens and lead to the peeling of the lens surface coating. The spring is prone to fatigue due to long-term compression stress, and the insertion block and the insertion slot may fall off due to the increased gap after the spring force decays. Therefore, we propose a large-size high-uniformity optical lens based on vapor deposition technology. SUMMARY

[0003] The present application aims to provide a large-size high-uniformity optical lens based on vapor deposition technology.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solution: a large-size high-uniformity optical lens based on vapor deposition technology, including a protective cover installed on a lens body and a mounting seat, a positioning plate connected to the upper surface of the mounting seat, a limiting slot opened on the side surface of the mounting seat, a clamping slot opened in the mounting seat, a sliding slot and a positioning hole opened on the upper surface of the mounting seat, a positioning rod clamped in the positioning hole, the positioning rod connected to a rotating plate, and the rotating plate clamped in the protective cover.

[0012] As a further scheme of the present application: the clamping block, the clamping groove, the connecting plate, and the sliding groove form a "double-direction guiding-stable locking" linkage function: when the connecting plate slides along the arc ring sliding groove, the clamping block is driven to synchronously slide along the arc ring clamping groove, the arc ring structures of the sliding groove and the clamping groove are matched, precise guidance is provided for the rotation of the protective cover, and the lens body is prevented from being pressed due to deviation of the protective cover; when the protective cover is rotated to a preset position, the clamping block can be completely clamped into the arc ring groove of the clamping groove, and the "plate-groove + block-groove" double locking structure is formed by cooperation of the connecting plate and the sliding groove, so as to prevent the protective cover from being axially or radially loose during use, and to ensure the stability of the installation of the lens body.

[0013] As a further scheme of the present application: the limiting block, the elastic spring, the pull rod and the limiting groove form an "elastic locking-convenient unlocking" linkage function: the elastic spring always applies an elastic pushing force to the limiting block towards the limiting groove, when the protective cover is turned to the locked position, the limiting block can be automatically clamped into the limiting groove under the action of the elastic spring, realizing the rotational locking of the protective cover, and avoiding accidental rotation of the protective cover; when unlocking is needed, pulling the pull rod can drive the limiting block to compress the elastic spring and disengage from the limiting groove, the unlocking process does not need to disassemble other components, the operation is convenient, and the elastic return action of the elastic spring can ensure that the cooperation between the limiting block and the limiting groove is always tight, reducing the risk of locking failure caused by the gap.
