AI Technical Summary

Technical Problem

The existing security lens cannot achieve true 4K image resolution when meeting the large zoom magnification, and the lens cover needs to be removed separately and is easily lost, making the operation cumbersome and less practical.

Method used

An ultra-high-definition resolution zoom lens is designed, which uses threaded connection between the lens holder and the lens cover. By rotating the lens cover, the baffle is pushed outward to achieve opening the cover, automatically reset when closing the cover, and using magnet bars and elastic rubber rings Ensure the occlusion effect and avoid the separate removal process of the lens cover.

Benefits of technology

It achieves the 4K ultra-high-definition resolution in 35X optical zoom, and simplifies the operation of the lens cover, avoids the cumbersomeness of the loss and disassembly process, and improves the efficiency and practicality of use.

Abstract

The utility model discloses an ultra-high-definition zoom lens, relates to the field of zoom lenses, solves the problems that an existing lens cover needs to be detached independently, is easy to lose, is tedious in operation and is lower in practicability, and adopts the following scheme: the ultra-high-definition zoom lens comprises a lens seat and a lens cover assembled on the front side of the lens seat; the outer end wall of the front side of the lens seat is provided with a screw thread part which rotates spirally, the inner side wall of the lens cover is provided with an inner screw groove which is matched with the specification of the lens cover, and the side edge part of the baffle plate is fixedly provided with a shaft seat which is provided with a shaft groove which is matched with the specification of the shaft column; a shaft column is fixedly installed on the inner side of the front end of the lens cover, and the lens cover is rotationally sleeved with a baffle through the shaft column. According to the ultra-high-definition zoom lens, through arrangement of the components on the lens cover, the inner sides of the baffle plates can be in contact with the end part of the lens barrel of the lens seat by rotating the lens cover, so that the two groups of baffle plates are propped outwards, and cover opening and cover closing can be realized by internally rotating the lens cover without independently disassembling the lens cover.
