Abstract

The present invention relates to the field of imaging technology, in particular to a lens, comprising a lens barrel, the lens barrel includes a first barrel wall forming a light hole and a second barrel wall bent and extended from the first barrel wall, the The second cylinder wall includes an inner wall and an outer wall opposite to the inner wall, the outer wall is provided with a multi-thread thread structure, and the multi-thread thread structure includes at least a first thread and a second thread, and the thread lines of the second thread are set between two adjacent turns of the first thread. In the lens provided by the present invention, the multi-thread structure is provided on the outer wall of the lens barrel, so that the lead of the multi-thread structure is multiple times of the pitch. Obviously, with this structure, the multi-thread structure is faster than the single-thread structure. That is to say, the lens can be screwed into the body and tightened with only a small number of rotations. Similarly, when disassembling, the number of rotations of the lens with multi-thread thread structure is also relatively small, which can improve the efficiency of lens disassembly and assembly. .

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to a lens. Background technique [0002] With the development of science and technology, many electronic devices such as digital cameras and mobile phones have lenses. The lenses are generally mounted on the body of the electronic device through threads. The external threads of the existing lenses are generally single-thread threads. , because the lead and pitch of the single-thread thread are equal, it takes multiple turns to tighten the lens and the body, and it also needs to turn multiple turns to separate the lens from the body when disassembling the lens. Obviously, the structure of this single-thread thread leads to The disassembly and assembly efficiency of the lens is relatively low. Contents of the invention [0003] The present invention provides a lens capable of solving the above problems. [0004] The present invention provides a lens, which includes a lens barrel,...
