Abstract

The invention discloses a video camera to improve the convenience of camera lens adjustment. The camera includes: a lens movement assembly, a bracket fixed on the lens movement assembly, wherein: a lens movement assembly, including a lens, a focus adjustment ring and a zoom adjustment ring arranged on the lens, and a focus adjustment structure fixed on the focus adjustment ring, The zoom adjustment structure fixed on the zoom adjustment ring; the bracket is located between the focus adjustment ring and the zoom adjustment ring, including the focus adjustment lever and the zoom adjustment lever that are rotatably installed on the bracket, the focus locking structure and the zoom adjustment lever fixed on the bracket magnification locking structure; the focal length adjustment lever abuts against the focal length adjustment structure, and the rotation of the focal length adjustment lever drives the rotation of the focal length adjustment structure; the zoom adjustment lever abuts against the zoom adjustment structure, and the rotation of the zoom adjustment lever drives the rotation of the zoom adjustment structure; The locking structure is used to limit the focus distance adjustment lever after the adjustment of the focus adjustment lever is completed, and the zoom locking structure is used to limit the position of the zoom adjustment lever after the adjustment of the zoom adjustment lever is completed.

Description

technical field [0001] The invention relates to the technical field of camera equipment, in particular to a camera. Background technique [0002] The manual zoom lens is an economical zoom lens. Compared with the electric zoom lens, the overall cost is lower than that of the electric zoom lens due to the reduction of the motor and the corresponding drive circuit structure. [0003] In the existing scheme of adjusting the manual zoom lens inside the camera, it is necessary to open the camera body and manually rotate the zoom lever to adjust the focal length and focus. Larger adjustment window, a large adjustment window will seriously affect the dust-proof and water-repelling effect of the camera, and sometimes limited by the shape of the camera, the adjustment window cannot be enlarged. In this way, there are various schemes for adjusting the manual zoom lens outside the camera. [0004] At present, in the solution of adjusting the manual zoom lens outside the camera, the l...
