Problems solved by technology

[0003] In the above method, since the lens can rotate, there is usually at least a gap of about 0.05mm. However, if the camera is used on a vibrating platform, the contact between the rear contacts and the camera lens will not be very good, or even fail. Flange distance may vary slightly due to clearance
Some designers propose to use springs to eliminate the above gap, but the springs are not stable enough to ensure a tight fit

Abstract

A lens limiting assembly (100), used for limiting a lens (310) provided with a clamping body (314) outside. The lens limiting assembly (100) includes: an elastic element (10); a lens assembly ring (20), which is arranged on the elastic element (10); after the lens (310) is assembled into the lens assembly ring (20), the clamping body (314 ) is clamped below the elastic element (10); and the locking ring (30), when the locking ring (30) rotates in one direction, the locking ring (30) resists and compresses the elastic element (10), so that the elastic element (10) Press the locking body (314) of the lens to lock the lens (310).

Description

technical field [0001] The invention relates to a lens limiting assembly, a camera body with the lens limiting assembly, and a camera with the body. Background technique [0002] The camera includes a lens and a body, and the lens is fixed or detachably connected to the body. To ensure stable imaging, it is necessary to ensure that the flange distance from the lens to the image sensor is as accurate as possible, so that the imaging will be stable and clear. The assembly method of the existing camera lens is to rotate the lens onto the body of the camera, hook it by the lens assembly ring on the body, and then add a lens release button assembly at the lens assembly ring, insert it into the lens, and prevent the lens from fall off. [0003] In the above method, since the lens can rotate, there is usually at least a gap of about 0.05mm. However, if the camera is used on a vibrating platform, the contact between the rear contacts and the camera lens will not be very good, or e...
