Abstract

The invention provides a lens of improving focusing accuracy rates. The lens of improving the focusing accuracy rates comprises a lens cone fixing seat, a driving canister and an elastic component, wherein the lens cone fixing seat is provided with a hollow out part, and the hollow out part is provided with a first top abutted part, the first abutted part is provided with a connecting part. The driving canister is provided with a canister groove and a pair of focusing lens cones on the inner edge of the circumference wall, and a guiding part is arranged on the out edge of the circumference wall, and the guiding part is embedded into the canister groove so that the focusing lens cones can be arranged inside the driving canister in an axial movement and containing mode. A second top abutted part is arranged on the inner edge of the circumference wall. The elastic part is in a hollow ring-shaped structure and can be capable of stretching in an axial mode, and the elastic part is arranged between the lens cone fixing seat and the pair of the focusing lens cones. One end of the elastic part is abutted against the first top abutted part of the lens cone connecting seat, and the other end of the elastic part is abutted against the second top abutted part. The lens of improving the focusing accuracy rates and a photographic device thereof have the advantages of being capable of improving the focusing accuracy rates, reducing the phenomenon of shining, meanwhile simplifying assembly technological process.

Description

technical field [0001] The invention relates to a lens, in particular to a lens capable of improving focusing accuracy and a photographic device thereof. Background technique [0002] At present, most of the cameras on the market have the functions of zooming and focusing, and for most of the current cameras, the zooming or focusing of the lens is mostly used to set a barrel groove in one lens barrel, and to set a barrel groove in the other. The guide part is set outside the lens barrel to be embedded in the barrel groove, and through the rotation of the lens barrel or the other lens barrel, one of the lens barrels is displaced axially to achieve a change in the distance between the two lens barrels to complete zooming or focusing Actions. [0003] However, there is usually a backlash problem between the groove and the guide (eg, the width of the groove is greater than the width of the guide). As far as the assembly process is concerned, this backlash can make the assembly...
