Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a diaphragm spacer that is convenient for installation. Background Art

[0002] In the field of photography, the diaphragm is usually called the aperture and is an important part of a camera lens. By adjusting the size of the aperture, a photographer can control the exposure amount, and thus control the brightness and depth of field of a photo. The larger the aperture, the greater the flux of light passing through, the higher the brightness of the photo, and at the same time the depth of field becomes shallower, making the clarity of the foreground and background different, forming a unique artistic effect. On the contrary, the smaller the aperture, the smaller the flux of light passing through, the lower the brightness of the photo, and the depth of field will be deeper, making the clarity of the entire picture higher.

[0003] When assembling a lens, in order to improve the photographic effect, it is necessary to install spacers on each component during lens assembly so that when it functions, light will not escape from the gaps between each component and the lens barrel and affect the imaging effect of the camera.

[0004] However, when the existing diaphragm is assembled, different from the lens having a fixed installation position and occupied space, the thickness of the diaphragm itself plus the thickness of the spacer makes it necessary to keep the diaphragm and the lens parallel to each other and coaxial during the process of pushing the diaphragm, resulting in the defect of inconvenient installation of the diaphragm.

[0005] Based on this, the utility model designs a diaphragm spacer that is convenient for installation to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a diaphragm spacer that is convenient for installation to solve the above technical problems.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: including a mounting base and a sealing plate; a relief groove and a placement groove are provided on the mounting base, a through hole and a plug-in groove are provided on the mounting base, and a limiting plate is fixedly arranged on the through hole; a connecting block is fixedly arranged on the sealing plate, and a limiting block is fixedly arranged on the connecting block; when the limiting block passes through the through hole and is plugged into the plug-in groove, the limiting block abuts against the limiting plate; three limiting blocks are provided; a clamping groove is provided on the sealing plate, and multiple clamping grooves are provided.

[0008] By adopting the above technical solutions, after placing the mounting base in the lens, placing the diaphragm in the placement groove, and placing the diaphragm adjuster in the relief groove, and then plugging the cover plate onto the mounting base, the installation method of the diaphragm is simple.

[0009] Preferably, the mounting base includes a mounting base plate and a cover plate. The insertion slot is formed in the mounting base plate, and the through hole is formed in the cover plate. The mounting base plate is provided with insertion holes, and the cover plate is fixedly provided with insertion blocks. Three insertion blocks are inserted into the insertion holes.

[0010] By adopting the above technical solution, the mounting base is designed as a split type, which simplifies the production and processing technology of the mounting base.

[0011] Preferably, the limiting plate is provided with a limiting groove, and the limiting block is fixedly provided with a limiting convex block. When the limiting block is inserted into the insertion slot, the limiting convex block is placed in the limiting groove.

[0012] By adopting the above technical solution, when the limiting block is inserted into the insertion slot, the limiting convex block placed in the limiting groove can prevent the sealing plate from falling off during use.

[0013] In summary, the present application has the following beneficial technical effects: Through the split design of the mounting base, the processing difficulty of the mounting base is reduced. When assembling the diaphragm, first place the mounting base in the lens, then place the diaphragm in the placement groove, and place the diaphragm adjuster in the relief groove. Subsequently, insert the cover plate into the mounting base, which has the advantage of simplifying the diaphragm installation method. Description of the Drawings
